In Whitehead’s process ontology, we can think of the experiential ground of reality as an eternal pulse whereby what is objectively public in one moment becomes subjectively prehended in the next, and whereby the subject that emerges from its feelings then perishes into public expression as an object (or “superject”) aiming for novelty. There is a rhythm of Being between object and subject, not an ontological division. This rhythm powers the creative growth of the universe from one occasion of experience to the next. This is the Whiteheadian mantra: “The many become one and are increased by one.” - Matthew Segall

Without Love there is no Truth. And True Truth is always Loving. There is no dichotomy between these terms but only seamless integration. This is the premier centering focus of a Processual Theology of Love. - R.E. Slater


Note: Generally I do not respond to commentary. I may read the comments but wish to reserve my time to write (or write from the comments I read).

So We're On the Same Page With One Another re Green Infrastructure, Green Energy & Green Tech

So We're On the Same Page With One Another
re Green Infrastructure, Green Energy & Green Tech

As a bible/theology/philosophic-theology site let us not forget that God is interested in ALL of his creation and not simply the homonid species alone. If we think of the Genesis Eden or the book of Revelation's thought of the "lion laying down with the lamb" there are many illustrations in the bible that any responsible theology should also include as a major section devoted to humanity living in rhythm and balance with earth's many disparate environments. Let us call such a study an "ecological theology" or "eco-theology" for short.

Here at Relevancy22 there have been many articles speaking to our concern of people of all faiths - including the Christian faith - learning to live not only with one another but with the earth in all its forms. My fav term-to-date describing such an arrangement is learning to build a socially and ecological just "cosmo-ecological civilizations" where cosmo = cosmic... or cosmopolitan... but "cosmopolitan" speaks only to "urbanized human societies" whereas "cosmic environmentalism" speaks to ALL of creation "both on the earth and in the heavens" along with humanity.

Since there are many good environmentally responsible sites speaking to rethinking our role on this earth - and since it is unnecessary for me to recapsulate these sites in some form of "sanctified" Christian-speak language - I will simply lay out three necessary forms of eco-socieities we must think about to get from where we are to where we should be heading:

  • Green Infrastructure
  • Green Energy
  • Green Tech

Moreover, it should not be necessary to state the obvious - that we, in our human societies, cannot accomplish such things if we cannot live in peace with one another. Earth is filled with multiethnic and religious cultures. Consequently, we as nation-states must learn to live in peace and goodwill with one another. Finding the best in one another and learning to work out the differences between one another.

If we cannot share earth's resources with one another in a responsible and fair manner, then neither may we expect to accomplish global eco-societies with one another when we're fighting with each other for water, land, and space. Amen? Yes, Amen.

PS - I snuck in a very important bible lesson here without saying the word God, love, or bible. Did you notice??  :)

What does the Greek word Allelon mean? "One another." The phrase "one another" is derived from the Greek word allelon which means "one another, each other; mutually, reciprocally." It occurs 100 times in the New Testament. Here's a complete list from Strong's Concordance. If anyone ever asks you what's the most important word in the bible, perhaps, allelon might be a grand reply and WHY you think it is an essential doctrine in the world of God's love - and supposedly, in the church's language -  which nowadays I hear very little about in the storm of individual rights, state's rights, and the church's right. In this life, while we live together with "ONE ANOTHER" there is no I in We, and no We's without communities of I's. - res

What is Green Infrastructure?

Runoff from stormwater continues to be a major cause of water pollution in urban areas. It carries trash, bacteria, heavy metals, and other pollutants through storm sewers into local waterways. Heavy rainstorms can cause flooding that damages property and infrastructure.

Historically, communities have used gray infrastructure—systems of gutters, pipes, and tunnels—to move stormwater away from where we live to treatment plants or straight to local water bodies.  The gray infrastructure in many areas is aging, and its existing capacity to manage large volumes of stormwater is decreasing in areas across the country. To meet this challenge, many communities are installing green infrastructure systems to bolster their capacity to manage stormwater. By doing so, communities are becoming more resilient and achieving environmental, social and economic benefits.

Basically, green infrastructure filters and absorbs stormwater where it falls. In 2019, Congress enacted the Water Infrastructure Improvement Actwhich defines green infrastructure as "the range of measures that use plant or soil systems, permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspirate stormwater and reduce flows to sewer systems or to surface waters."

Green infrastructure elements can be woven into a community at several scales. Examples at the urban scale could include a rain barrel up against a house, a row of trees along a major city street, or greening an alleyway. Neighborhood scale green infrastructure could include acres of open park space outside a city center, planting rain gardens or constructing a wetland near a residential housing complex. At the landscape or watershed scale, examples could include protecting large open natural spaces, riparian areas, wetlands or greening steep hillsides. When green infrastructure systems are installed throughout a community, city or across a regional watershed, they can provide cleaner air and water as well as significant value for the community with flood protection, diverse habitat, and beautiful green spaces.

What is Green Energy?

Green energy is any energy type that is generated from natural resources, such as sunlight, wind or water. It often comes from renewable energy sources although there are some differences between renewable and green energy, which we will explore, below.

The key with these energy resources are that they don’t harm the environment through factors such as releasing greenhouse gases into the atmosphere.

How Does it Work?

As a source of energy, green energy often comes from renewable energy technologies such as solar energy, wind power, geothermal energy, biomass and hydroelectric power. Each of these technologies works in different ways, whether that is by taking power from the sun, as with solar panels, or using wind turbines or the flow of water to generate energy.

What Does it Mean?

In order to be deemed green energy, a resource cannot produce pollution, such as is found with fossil fuels. This means that not all sources used by the renewable energy industry are green. For example, power generation that burns organic material from sustainable forests may be renewable, but it is not necessarily green, due to the CO2 produced by the burning process itself. 

Green energy sources are usually naturally replenished, as opposed to fossil fuel sources like natural gas or coal, which can take millions of years to develop. Green sources also often avoid mining or drilling operations that can be damaging to eco-systems.

Types of Green Energy

The main sources are wind energy, solar power and hydroelectric power (including tidal energy, which uses ocean energy from the tides in the sea). Solar and wind power are able to be produced on a small scale at people’s homes or alternatively, they can be generated on a larger, industrial scale.

The six most common forms are as follows:

1. Solar Power

This common renewable, green energy source is usually produced using photovoltaic cells that capture sunlight and turn it into electricity. Solar power is also used to heat buildings and for hot water as well as for cooking and lighting. Solar power has now become affordable enough to be used for domestic purposes including garden lighting, although it is also used on a larger scale to power entire neighbourhoods.

2. Wind Power

Particularly suited to offshore and higher altitude sites, wind energy uses the power of the flow of air around the world to push turbines that then generate electricity.

3. Hydropower

Also known as hydroelectric power, this type of green energy uses the flow of water in rivers, streams, dams or elsewhere to produce energy. Hydropower can even work on a small scale using the flow of water through pipes in the home or can come from evaporation, rainfall or the tides in the oceans.

Exactly how ‘green’ the following three types of green energy are is dependent on how they are created…

4. Geothermal Energy

This type of green power uses thermal energy that has been stored just under the earth’s crust. While this resource requires drilling to access, thereby calling the environmental impact into question, it is a huge resource once tapped into. Geothermal energy has been used for bathing in hot springs for thousands of years and this same resource can be used for steam to turn turbines and generate electricity. The energy stored under the United States alone is enough to produce 10 times as much electricity as coal currently can. While some nations, such as Iceland, have easy-to-access geothermal resources, it is a resource that is reliant on location for ease of use, and to be fully ‘green’ the drilling procedures need to be closely monitored.

5. Biomass

This renewable resource also needs to be carefully managed in order to be truly labelled as a ‘green energy’ source. Biomass power plants use wood waste, sawdust and combustible organic agricultural waste to create energy. While the burning of these materials releases greenhouse gas these emissions are still far lower than those from petroleum-based fuels.

6. Biofuels

Rather than burning biomass as mentioned above, these organic materials can be transformed into fuel such as ethanol and biodiesel. Having supplied just 2.7% of the world’s fuel for transport in 2010, the biofuels are estimated to have the capacity to meet over 25% of global transportation fuel demand by 2050.

Why It Is Important?

Green energy is important for the environment as it replaces the negative effects of fossil fuels with more environmentally-friendly alternatives. Derived from natural resources, green energy is also often renewable and clean, meaning that they emit no or few greenhouse gases and are often readily available.

Even when the full life cycle of a green energy source is taken into consideration, they release far less greenhouse gases than fossil fuels, as well as few or low levels of air pollutants. This is not just good for the planet but is also better for the health of people and animals that have to breathe the air.

Green energy can also lead to stable energy prices as these sources are often produced locally and are not as affected by geopolitical crisis, price spikes or supply chain disruptions. The economic benefits also include job creation in building the facilities that often serve the communities where the workers are employed. Renewable energy saw the creation of 11 million jobs worldwide in 2018, with this number set to grow as we strive to meet targets such as net zero.

Due to the local nature of energy production through sources like solar and wind power, the energy infrastructure is more flexible and less dependent on centralised sources that can lead to disruption as well as being less resilient to weather related climate change.

Green energy also represents a low cost solution for the energy needs of many parts of the world. This will only improve as costs continue to fall, further increasing the accessibility of green energy, especially in the developing world.


There are plenty of examples of green energy in use today, from energy production through to thermal heating for buildings, off-highway and transport. Many industries are investigating green solutions and here are a few examples:

1. Heating and Cooling in Buildings

Green energy solutions are being used for buildings ranging from large office blocks to people’s homes. These include solar water heaters, biomass fuelled boilers and direct heat from geothermal, as well as cooling systems powered by renewable sources.

2. Industrial Processes

Renewable heat for industrial processes can be run using biomass or renewable electricity. Hydrogen is now a large provider of renewable energy for the cement, iron, steel and chemical industries.

3. Transport

Sustainable biofuels and renewable electricity are growing in use for transportation across multiple industry sectors. Automotive is an obvious example as electrification advances to replace fossil fuels, but aerospace and construction are other areas that are actively investigating electrification.

Can It Replace Fossil Fuels?

Green energy has the capacity to replace fossil fuels in the future, however it may require varied production from different means to achieve this. Geothermal, for example, is particularly effective in places where this resource is easy to tap into, while wind energy or solar power may be better suited to other geographic locations.

However, by bringing together multiple green energy sources to meet our needs, and with the advancements that are being made with regards to production and development of these resources, there is every reason to believe that fossil fuels could be phased out.

We are still some years away from this happening, but the fact remains that this is necessary to reduce climate change, improve the environment and move to a more sustainable future.

Can It Be Economically Viable?

Understanding the economic viability of green energy requires a comparison with fossil fuels. The fact is that as easily-reached fossil resources begin to run out, the cost of this type of energy will only increase with scarcity.

At the same time as fossil fuels become more expensive, the cost of greener energy sources is falling. Other factors also work in favour of green energy, such as the ability to produce relatively inexpensive localised energy solutions, such as solar farms. The interest, investment and development of green energy solutions is bringing costs down as we continue to build up our knowledge and are able to build on past breakthroughs.

As a result, green energy can not only become economically viable but also the preferred option.

Which Type Is The Most Efficient?

Efficiency in green energy is slightly dependent on location as, if you have the right conditions, such as frequent and strong sunlight, it is easy to create a fast and efficient energy solution.

However, to truly compare different energy types it is necessary to analyse the full life cycle of an energy source. This includes assessing the energy used to create the green energy resource, working out how much energy can be translated into electricity and any environmental clearing that was required to create the energy solution. Of course, environmental damage would prevent a source truly being ‘green,’ but when all of these factors are combined it creates what is known as a ‘Levelised Energy Cost’ (LEC).

Currently, wind farms are seen as the most efficient source of green energy as it requires less refining and processing than the production of, for example, solar panels. Advances in composites technology and testing has helped improve the life-span and therefore the LEC of wind turbines. However, the same can be said of solar panels, which are also seeing a great deal of development.

Green energy solutions also have the benefit of not needing much additional energy expenditure after they have been built, since they tend to use a readily renewable source of power, such as the wind. In fact, the total efficiency of usable energy for coal is just 29% of its original energy value, while wind power offers a 1164% return on its original energy input.

Renewable energy sources are currently ranked as follows in efficiency (although this may change as developments continue):
  1. Wind Power
  2. Geothermal
  3. Hydropower
  4. Nuclear
  5. Solar Power 

How Can it Help the Environment?

Green energy provides real benefits for the environment since the power comes from natural resources such as sunlight, wind and water. Constantly replenished, these energy sources are the direct opposite of the unsustainable, carbon emitting fossil fuels that have powered us for over a century.

Creating energy with a zero carbon footprint is a great stride to a more environmentally friendly future. If we can use it to meet our power, industrial and transportation needs, we will be able to greatly reduce our impact on the environment.

Green Energy vs Clean Energy vs Renewable Energy – What is the Difference?

As we touched upon earlier, there is a difference between green, clean and renewable energy. This is slightly confused by people often using these terms interchangeably, but while a resource can be all of these things at once, it may also be, for example, renewable but not green or clean (such as with some forms of biomass energy).

Green energy is that which comes from natural sources, such as the sun. Clean energy are those types which do not release pollutants into the air, and renewable energy comes from sources that are constantly being replenished, such as hydropower, wind power or solar energy.  

Renewable energy is often seen as being the same, but there is still some debate around this. For example, can a hydroelectric dam which may divert waterways and impact the local environment really be called ‘green?’

However, a source such as wind power is renewable, green and clean – since it comes from an environmentally-friendly, self-replenishing and non-polluting source.


Green energy looks set to be part of the future of the world, offering a cleaner alternative to many of today’s energy sources. Readily replenished, these energy sources are not just good for the environment, but are also leading to job creation and look set to become economically viable as developments continue.

The fact is that fossil fuels need to become a thing of the past as they do not provide a sustainable solution to our energy needs. By developing a variety of green energy solutions we can create a totally sustainable future for our energy provision, without damaging the world we all live on.

What is Green Technology in 2022?
The Greentech, Climate Tech & Cleantech Guide

GREENTECH LINK           Reading Time - 16 min

Green technology in 2022 is the intersection of much new terminology and a wide range of innovative solutions around energy production, pollution reduction, and climate change reversal. Here we offer a Complete Guide to Greentech – new environmental technology including Climate Tech, Cleantech and everything in between.

Consumer awareness of human impact on the planet is on the rise, with it green technology is growing, adapting and developing. Following on from last year’s COP26 event in Glasgow, 2022 is set to be a year of extensive greentech growth and development after numerous government committments. This is in addition to the many recent documentaries, television programmes by David Attenborough, protests from Extinction Rebellion and multiple speeches by Greta Thunberg, which have placed the issues of climate change and the environment in front of the consumer.

Joe Biden has taken office as President of the United States and has made many public statements that his term will see the US pursue a strong green agenda.

Everything from fashion to energy consumption will be impacted by government there and worldwide, and personal goals to tackle the pressing threat of environmental problems. Therefore, being aware of key terms and developments will keep you ahead of the trends as we embrace a greener lifestyle.

To stay ahead of recent trends and developments, we will be taking an in-depth look at green technology in 2022. This article outlines what green technology is, some key terms and their definitions, developments in greentech, types of technologies being developed, and leading companies within each type.

What is Greentech?

Greentech is often split into two areas that are referred to as climate tech and cleantech. Between them, their technologies look to deal with existing and future damage to the environment caused by humans, as well as reducing or eliminating sources of further damage from our energy production and pollution.

Although there is current speculation around the use of these terms and whether there are better alternatives out there, we will be referring to each technology as a section within these two areas.

Clean Energy Ventures defines climate tech as “expressly concerned with the mitigation of greenhouse gas emissions” and cleantech as focusing on humanity’s impact on the environment.

Climate tech has a focus on greenhouse gas emissions so therefore includes sectors such as carbon capture and afforestation. The focus of these sectors is to reduce the severity of greenhouse gas emissions, either through trapping the already existing gases or considering how greenhouse gases can be reduced moving forward.

We can define this area by considering whether the sector considers its impact on the planet beyond greenhouse gas emissions, if there is little consideration or this has been considered but the impact on greenhouse gas emissions is greater then the main goal of the company or project sits within climate tech.

Cleantech looks at cleaning humanity’s impact from the environment. This includes areas like pollution and air quality as well as recycling and waste management.

These sectors don’t necessarily consider the impact of this work on emissions but know that the work will impact and reduce humanity’s impact on the wider environment. For example, recycling and waste management may require vehicles or machines that emit greenhouse gases but the impact on human waste seeping into oceans or waterways is reduced, therefore its focus is cleantech.

Greentech in 2022

Within the two areas of climate tech and clean tech, we find a whole host of sectors that focus on certain aspects of business and society that make up the landscape of greentech in 2022. Some of these sectors solely occupy climate tech or cleantech, others overlap and look at both areas in order to create change in society.

For example, clean energy is concerned with mitigating greenhouse gas emissions while also reducing human impact on the environment through the extraction of resources to be used for creating energy.

Though the terms are sometimes used interchangeably, they do not mean the same thing. The two areas share similar ideas but the overall goals they are working towards are different. Some companies and sectors may overlap in their actions and ideas but returning to the main goal of their actions is the best way to understand what area they belong within. Placing green technologies within the two areas allows us a better understanding of the goals driving those technologies and the key focus of companies who work within that sector, defining every action they take in order to ensure effectiveness and efficiency.

Below you’ll find a useful diagram from Clean Energy Ventures that outlines many of the green technology sectors that are explored throughout this article, and highlights the intersection and difference between cleantech and climate tech:

Cleantech vs Climate Tech Diagram by Clean Energy Ventures

What is climate tech?

Climate tech is green technology that focuses on the reduction and mitigation of the effect of greenhouse gas emissions. This includes both reducing the greenhouse gases currently being produced, capturing or removing the greenhouse gases that are currently in our atmosphere and reducing the greenhouse gases that will be emitted in the future.

Carbon Capture

Carbon dioxide is the main gas contributing to global heating, therefore the thinking behind carbon capture involves catching the carbon at the source of it being created and then piping it to a place where it can be stored or used. It can be used as the carbon dioxide for things like carbonating drinks but can also be used to create hydrogen which can be used in factories as a clean-burning fuel. According to the IEA, carbon capture could reduce global carbon dioxide emissions by 70% (The Guardian, 2020).

Carbon capture allows manufacturers to avoid expense in adapting to run on clean energy and the technology already exists in order to get carbon capture projects up and running. It also opens up new business opportunities in creating hydrogen which could then be sold on as fuel.

Developments around new environmental technology in 2022 include efforts by the UK National Grid who have already set up a large carbon capture project in the Yorkshire and Humber region, and are now looking to continue developing on this work with their partners Drax and Equinor. The project could see the Humber become the world’s first net zero carbon region. For this project, the carbon is taken from industrial factories in this region and piped into storage in the North Sea.

The “storage” is a porous rock under the seabed which is injected with liquid carbon dioxide. Alongside this project, Phillips 66, Uniper and Vitol have proposed the Humber Zero decarbonisation project, placing the UK as global leaders of carbon capture technology alongside Scandinavia and the United States.

Finally, a UN report has recently called for an increase in the use of carbon capture in order to drastically combat climate change, identifying key barriers to the development of this technology. The future looks promising for carbon capture, especially for UK businesses who may benefit from world-first net zero manufacturing.


Afforestation is the creation or establishment of a forest where there was previously no tree cover. This action aids carbon capture but the trees also reduce carbon dioxide levels and add more oxygen into the atmosphere, helping to reduce greenhouse gas emissions.

A number of government and non-government organisations partake in planting trees to offset their carbon emissions, including government goals to achieve within a set time as part of the action to tackle climate change. There is also scope to use other technologies within afforestation plans to speed up the process and some businesses build tree-planting into their product as a benefit to the eco-conscious consumer.

Symbiosis Investimentos is a Brazilian privately owned investment company that transforms degraded areas into established forests by restoring native species, working within the timber industry to improve quality of wood and quality of the planet.


Agtech is short for agricultural technology and includes a whole range of companies that support the agriculture industry to become greener. From smart robots that gather data from crops to reducing livestock manure through LIvestock Water Recycling (LWR), this sector encompasses a range of innovative technological developments to improve efficiency of agriculture and mitigate greenhouse gases.

As outlined by Deloitte (2016), agriculture businesses are having to be more open to innovation and change in order to keep up with the changes in the market. Their report also predicts that start-ups and innovators will seek to disrupt the industry through the introduction of new technology.

Future Growing LLC is an industry-leader in Agtech through the development of the aeroponic growing process which removes the need for soil when growing herb crops and places these crops in vertical towers, instead of into long rows in the ground.


Commonly referred to as climate engineering, geo engineering is a large-scale intervention in the climate system of the Earth. Within this sector, there are a number of subcategories such as solar radiation management and carbon dioxide removal. Climate engineering looks predominantly to environmental modelling to present solutions to current problems placing much of the work in this area as theoretical and difficult to action in the short-term.

Projects can be expensive and risky but given the current climate emergency, could provide a breakthrough to complement the work of other sectors.

The Climeworks’ direct air capture technology allows the company to suck carbon dioxide straight from the air with a similar route for the carbon dioxide as carbon capture, storing it below ground. This is an expensive process and will not be enough to solve climate change alone.

Alongside this work, there is a solar geoengineering research project run by Harvard University (Voosen, 2020) that hopes to use particles in the atmosphere to block the sun’s rays and therefore prevent the warming of the Earth.

The project has made progress using models and theories and is now looking to release a balloon into the atmosphere, release chalky particles and then monitor what happens.

Climeworks is one of the companies profiled on the Elevate Green website, which looks at products, services and projects that will help to reduce the environmental impact of industry, protect nature, or actively reverse the negative impacts we have already had on our environment and the global climate.

What is cleantech?

Cleantech is green technology that increases the performance, productivity or efficiency of production while reducing the impact on the environment. The technology may focus on the impact on a particular environmental element, such as water or air, that would normally be subjected to chemicals or pollutants as part of the production process. Some of these technologies might impact or influence your day-to-day life without you even realising.

Clean Water

Water is essential for human life yet universal access to clean water is not available. Innovative technologies for clean water allow communities across the world to thrive and grow, promoting the growth of families, businesses and education in places where this wasn’t possible before. On top of this, as the global population grows and industries use more and more water for manufacturing, having enough clean water for everyone is a rising concern.

Supporting businesses to clean and re-use water creates a cycle where new water does not need to enter the process, allowing that water to be used elsewhere in the community.

Innovative Water Technologies developed water filtration systems that were portable, solar and wind powered and reliable, providing 20,000 litres of clean water every day for 10 years or more. The Lifestraw is another portable technology that filters water as you drink, providing much-needed water access during emergencies where clean water might not be readily available.

Recycling and Waste

What we do with our waste matters. Whether it is household waste or manufacturing waste, for a long time we were just dumping waste into the ground or the ocean and we have now realised that eventually, the space will run out.

On top of that, the waste will poison our sources and make growing food or finding clean water more difficult. Recycling programmes have been rolled out globally, with governments changing their approaches to waste and changing behaviours of entire nations in the process.

Most recently, plastic recycling has come to the forefront of this sector. Plastics are hard to recycle due to them being mixed with other things in the production process and therefore becoming hard to separate and take back to its original form.

Unlike something like glass which can simply be melted down and reformed several times over its lifetime. PureCycle aims to reduce plastic waste through research and development of the recycling process to create pure recycled polypropylene that can be used in an endless loop.

Air quality and Pollution

Air quality impacts health. It’s as simple as that. Poor air quality will impact people living and working in that area, causing the development of new and underlying illnesses and making existing illnesses worse.

On top of people, air quality impacts the growth of wildlife and nature, impacting the ability of trees to photosynthesise and respire and therefore affecting the homes and lives of wildlife.

The UK government has researched into air pollution and its impacts on people, creating a specific website to track air pollution across the UK. The use of data to create real time images and forecast future pollution is a way to support those whose health may be impacted in times of peak air pollution, choosing to avoid certain times and areas for being outside.

On top of this, the UK now has years of data tracking air quality and pollution across the entire country, which can be drawn upon to create technological developments that can help to find a resolution.

Cleantech and Climate tech

Where cleantech and climate tech overlap, we find sectors that permeate every aspect of society and our existence. Everything from moving goods around the world to the careful choice of energy providers by businesses and consumers.

From a business perspective, these sectors are at the forefront of the green technology impact on how a business looks to grow and develop in the future. These sectors also provide interesting approaches and insights on how consumers and businesses can impact the environment through small changes in behaviours and choices.

Clean Energy

Clean energy is probably the most well-known environmental industry, from wind farms to solar panels. Clean energy is technology that creates energy from renewable, zero emission sources. These are probably the most familiar technologies to us out of all green technologies.

Many companies in this sector are thriving through businesses and consumers demanding access to green energy, supported by the emergence of a number of challenger energy providers who can offer green energy at a competitive rate and have enjoyed rapid growth.

One of the most recent developments in clean energy is floating solar panels which removes the use of soil while still allowing the capture of energy from the sun. This is a promising growth trend for this sector and has been widely tested in Japan, China and Southeast Asia, countries which will need this adaptation in order to cope with their lack of accessible land. Water-based panels also improve the performance of panels as the water and winds cool the cells.

The use of renewable hydrogen opens up a new opportunity for businesses, set to grow to a size similar to the oil and gas industry with much lower rates of emissions, there is a lot of potential here that has been grasped by industry experts.

Over 10 countries are currently competing to be world leaders, and Air Liquide is one company who has recently announced plans to introduce 200 hydrogen filling stations across the US by 2025.

With so much clean energy already present in our lives, this sector presents many promising opportunities for development, whether that be in wind, turbo, geothermal, solar or somewhere else. The technology is accessible with lots of work already completed which allows new innovators room to adapt, develop and grow the already-existing technology.

Emerging Trends #5: CleanTech and Climate Tech
Mar 20, 2020

Built Environment

When referring to built environment, we mean buildings and human structures. The adoption of green technology in construction helps to increase the efficiency of the building in staying warm or cool, using water effectively and ensuring that your building materials have a low impact on the environment.

From simple things such as green insulation made from recycled materials to electrochromic smart class that electrically charges windows to change the amount of solar radiation they reflect, the choices range wildly between simple solution and ultra-technological design.

Biotecture is a company that designs and builds living walls made from plants for community and work spaces, reconnecting people with nature in their everyday spaces. The company can create both interior and exterior living walls that provide a calming feel to any space.

They have created work for Centrica, Heathrow Airport, Smeg stores and other spaces, making a stand-out impact on visitors and workers who regularly use these spaces. By introducing plants, the interior air quality is improved and the actions taking place within the space improve too.


Transport encompasses public and personal transport as well as the transportation of goods around the world. In the clean tech sector, the main discussion is currently around the use of cars, electric cars and charging stations for electric cars.

Governments are placing bans on the creation of new petrol and diesel cars to accelerate the industry’s development and the public’s uptake of electric vehicles, making developments in this area crucial to car manufacturers and the success of electric vehicles with the public.

AFC energy recently unveiled a new hydrogen-powered rapid charger to support the introduction of electric vehicles and improve options of charging vehicles efficiently. The charger, called CH2ARGE, sees compressed hydrogen delivered to on-site units that use the gas to generate electricity, stored in a 40kW battery which can then be used to rapidly charge an electric vehicle.

Supply Chain

Environmentally friendly practices can be implemented at almost every stage of the supply chain. From packaging options to transporting goods, companies can choose green solutions to help decrease the environmental impact of their business and products. These options are becoming more popular due to being cost-effective and planet-friendly.

Examples of green technology in the supply chain may be ethical sourcing, closed-loop manufacturing and reducing fuel emissions. Consumers are becoming more invested in the impact their purchase may have on the planet so will carefully research a company’s supply chain before considering buying.

Greenpeace have created a report which documents the progress made by industries and companies globally – Destination Zero. The report also highlights barriers and makes suggestions for how these could be overcome in the future, challenging the global market to do better and strive for further progress.

With relation to drinks, Good Things Brewing Company, based in Sussex, UK, has recently unveiled a closed-loop brewery and implements several green options within their supply chain, such as using cans instead of bottles as they are lighter to transport and using a fleet of electric vehicles to deliver their products.

The closed-loop brewery means they keep their sources within the loop of their brewery, treating waste on site and using the water elsewhere in the business as well as creating their own energy through photovoltaic panels.

The future of green technology

As the market of green technology grows there are new opportunities for businesses and governments to fund prospective projects and ideas that may grow into a world-saving technology. As climate change and environmental issues have been carefully portrayed as societal, governmental and individual issues, the general public are looking for ways to support and promote products and practices that are friendly to the planet.

Investing is becoming a popular way to save and grow money towards financial goals and through the development of investing platforms and the prominence and access of finance education on social media platforms, more people are considering investing their money in order to make it grow.

With this readily available information and climate issues at the forefront of society, green investing (or ESG investing) is gaining traction with investors around the world. The coronavirus pandemic has intensified discussions about the interconnectedness of finances and green technology, resulting in key trends in climate change and social unrest emerging as areas important to investors.

What is ESG Investing?

ESG stands for Environmental, Social and Governance. These are non-financial factors that can be selected when you choose to invest your money. These factors are not mandatory but companies are increasingly disclosing information linked to their sustainability.

There is also demand from investors for these factors which is, in turn, influencing companies to disclose and ensure they look good to secure investors’ wealth.

It is key to know that there are no ESG standards that companies have to follow, therefore there is not one list for comparing. ESG factors link and can be hard to classify in one area and the factors can often be measured but sometimes do not have a monetary value.

ESG investing is similar to Socially Responsible Investing (SRI) but they are not the same. SRI has a process of screening with a specific set of criteria whereas ESG looks for a broader sense of value.

In Summary

Cleantech and climate tech are amazing areas of technology and innovation, offering up opportunities to support businesses, agriculture, health and future generations.

Green technology has seen real ebbs and flows in public interest and government support, but in 2022 it looks like green technology is only going to rise and rise through government targets to reduce the climate’s temperature growth and through the empowerment of individuals looking to invest their money where it will make an environmental and social impact to support generations to come.
