Power to the People: An Overview of Community Energy

FEB 2ND 2024
Worldwide, citizen-led renewable energy initiatives are paving the way towards a just transition and resilient energy systems. This article provides an overview of community energy, outlining the benefits, obstacles, and way forward for grassroots efforts to implement the renewable energy transition. The renewable energy transition calls to mind sprawling solar arrays, offshore wind farms, and policymakers setting net-zero targets at global conferences. Nevertheless, a less-known yet equally important approach to a clean energy future exists.Community energy – also referred to as “local energy communities” or “renewable energy communities” – refers to locally based, small-scale renewable energy projects that are set up, owned by, and in service of different types of communities, from neighborhoods and cooperatives to nonprofits and small businesses.

Worldwide, advocates of these projects work for a renewable energy transition powered by people – where citizens invest in locally based, collectively owned renewable energy projects such as rooftop solar, local wind turbines and hydropower plants. Energy produced by these projects can be used to power everything from homes and schools to businesses and public buildings.

Projects vary in how they function, who they serve, and their relationship to main electricity grids. But by enabling people to be both energy producers and consumers – or “prosumers” – community energy has the potential to accelerate a just transition and create resilient energy systems.

An Introduction

The concept of community-led energy projects is not new – in the 19th and early 20th centuries, energy cooperatives in the US and Europe electrified rural areas. Community energy projects for the renewable energy transition, however, are a recent phenomenon.

Europe’s early efforts to transition to renewable energy in the 1980s were driven by community-owned wind farms, notably in Germany and Denmark. Initiatives increased with environmental awareness. A 2023 study revealed a rise in community energy in Europe over the past two decades in line with “collective action for the low carbon transition.” As of 2020-21, there were around 2 million people involved in 23,000 community energy projects across 30 European countries.

The European Union (EU) sees it as a key part of Europe’s energy future. In 2019 an EU directive defined and enabled “citizen energy communities”, while a 2020 report by the European Commission anticipates that 45% of Europe’s renewable energy will be community-owned by 2050.

While Europe leads the community energy revolution, examples of citizen-led renewable energy projects can be found across the world; from Revolu Solar, a non-profit installing community-owned solar in Brazil’s favelas, to the Barr River Hydro Scheme, which delivers 100% community-owned hydropower to 1,000 homes in Scotland.

Working for a Just Transition

From enforced blackouts and runaway energy bills to wildfires and explosions caused by faulty transmission lines – global energy markets and the utility-led energy model have historically prioritised profit over people. Community energy offers an alternative energy system that serves and supports citizens in the transition to renewables.

As community-owned energy projects are protected from volatile global energy markets, prosumers are not held to market prices and can receive lower energy bills. During the recent Europe-wide energy crisis, it was reported that some European community energy users paid half the amount in energy bills as customers who received their electricity from commercial utilities.

And many projects choose to reinvest their profits back into the communities they serve, creating a regenerative energy economy. For example, UK-based organisation Energy Garden uses revenue from their community-owned solar projects in London to run environmental internships and youth education programmes.

Community energy organisations serve as powerful community advocates when corporation-led renewable energy projects come into a neighbourhood. The community organisation UPROSE established the first cooperatively owned solar project in New York City, Sunset Park Solar. As the Norwegian energy company Equinor sites an offshore wind facility near Sunset Park, UPROSE is working to ensure the community is not left behind and has a stake in the future renewable energy economy through providing education and jobs training in offshore wind.

Projects can also be a tool to encourage local support for the energy transition. A report by the Institute for Local Self-Reliance references a 2011 study that found “45% of residents of a German town home to community-owned wind turbines had a positive opinion of future local wind development, compared to only 16% in another town with a wind project owned largely by outside entities.”

By fostering citizen support, community energy accelerates the switch to renewables while paving the way toward an energy future that everyone is on board with.

Resilient Energy Systems 

These community-led projects offer a solution to one of the biggest roadblocks on the path to net-zero – electricity grids.

Last year, an analysis by the International Energy Agency (IEA) found that global electricity grids are in urgent need of upgrades to support the transition. According to the study, 80 million kilometres of electricity grids will need to be added or refurbished by 2040 – the equivalent of doubling the global grid. This will be a long and costly process with investments in grid infrastructure required to double to more than US$600 billion a year.

Many citizen-led energy projects operate on decentralised, local energy generation models that do not require vast networks of transmission lines. Distributed Energy Resources (DERs) such as rooftop solar allow citizens to generate energy near the site of use. Multiple DERs can be aggregated to form a community microgrid, which can operate in “island mode”, enabling communities to access renewable energy without the need to wait for grid upgrades.

An additional benefit of community-based energy generation is a safer and more reliable energy system. Adding more local, decentralised projects into the mix takes pressure off electricity grids, helping to prevent power outages, wildfires, and other challenges faced by overloaded grids.

Lastly, community energy can provide an alternative source of power when disaster strikes.

When Puerto Rico was hit by Hurricane Maria in 2017 and Hurricane Fiona in 2022, the electricity grid failed, leaving millions without power. But a few homes and businesses in the Castañer region were able to keep their lights on, powered by a micro-grid set up by The Cooperativa Hidroeléctrica de la Montaña, Puerto Rico’s first renewable energy cooperative.

Following the devastating hurricanes, Puerto Ricans began working to bring more decentralised, community-owned energy into the mix. Last year, Adjuntas, a town in the mountains of Puerto Rico, completed a cooperatively-owned solar microgrid with the capacity to power the community of 17,600 – an example of how these projects can be a powerful tool for creating both resilient communities and energy systems.

Obstacles to Community Energy

Despite the benefits these initiatives are showing in the transition to renewables, many obstacles stand in the way.

Worldwide, government approaches to the energy transition prioritise the build-out of utility-scale renewable energy projects. But support of community energy does not always translate into action.

For instance, while the UK’s Net Zero Strategy outlines the benefits of these projects, the organisation Community Energy England criticised the strategy for failing to provide practical measures supporting citizen-led renewable energy initiatives.

In an energy market dominated by corporations working on a top-down, centralised energy system, community energy projects also struggle with everything from accessing finance to invest in initiatives, to navigating the complex legal and bureaucratic processes involved in setting up projects and connecting them to the grid.

Even Europe’s energy market has become less favourable to such projects in recent years, with the removal of policies and subsidies incentivising them.

A 2020 report by Trade Unions for Energy Democracy found that the end of the Feed-in Tariff (FiT) subsidy has led community energy projects across Europe into “a pattern of decline.”

What’s more, these projects can face direct opposition from utilities seeking to protect their profit and dominant position in the market. Recent plans for a community solar program in California, a leader in solar in the US, have been opposed by the state’s three main energy utilities. Activists say this is just the most recent development in a decade-long campaign waged by utilities to block community energy in the state.

Community energy also faces social obstacles. Most people encounter energy as a service delivered by utilities, rather than something they are actively involved in, and awareness of community energy schemes is generally low. For example, a 2023 poll commissioned by the Bristol Energy Cooperative found that only 1% of respondents feel well informed on community energy. For these projects to play an impactful role in the energy transition, there needs to be more education and awareness so people can identify and set up initiatives to bring local, renewable energy into their communities.

Towards Energy Democracy

Energy Democracy, a grassroots movement working for equitable, community owned energy to play a central role in the transition, has emerged as a response to these obstacles.

The Climate Justice Alliance defines the movement’s goal as a “shift from the corporate, centralised fossil fuel economy to one that is governed by communities, is designed on the principle of no harm to the environment, supports local economies, and contributes to the health and well-being for all peoples.”

Energy Democracy activists work toward this goal through advocating for policy enabling citizen-owned renewable energy and have so far achieved some impressive wins.

The California Environmental Justice Alliance, a coalition of grassroots organisations working for Energy Democracy, set up the Solar on Multifamily Affordable Housing Program, which provides up to US$1 billion for rooftop solar on low-income households in the state. Similarly, the UK Energy Democracy campaign group Power for People successfully lobbied for a £10 million (US$12.7 million) fund to set up community energy projects across the country.

The Energy Democracy movement also works to increase awareness about these projects. In 2022, the Energy Democracy Project, more than 30 Energy Democracy organisations across the US launched the Reimagined Energy For Our Communities (REFOCUS) campaign to share stories of everyday citizens taking control of their energy systems. By showing the possibilities of citizen-led energy initiatives, the REFOCUS campaign empowers communities to take the energy transition into their own hands.

Conclusion

The ways in which the energy transition impacts people are increasingly being recognised. A chapter of the IEA’s World Energy Outlook 2023 report was dedicated to “[s]ecure and people-centred energy transitions”, addressing the need for energy access, affordability, and employment in the transition to renewables.

As the social challenges associated with energy transition are considered, community energy must stay part of the conversation and recognised for the solutions it provides. Despite the manifold obstacles these projects face, there are also encouraging signs – last year, the IEA hosted a webinar with global leaders in the community energy space and published an article outlining its benefits.

To harness these benefits, governments and markets need to support and facilitate community energy initiatives and organisations through policy and investment. Simultaneously, society needs to recognise and amplify the voices and actions of Energy Democracy activists and similar movements to bring about a clean and equitable energy future.

Expectations vs reality: The truth about architecture as a career

A realistically impregnated Opinion of  published in Building Design compares expectations vs reality in truth concerning architecture as a career in the UK. Would it be the same elsewhere, say in the MENA region?

Expectations vs reality: The truth about architecture as a career

 

There is a huge mismatch between how the architectural profession is perceived and the reality, writes Aylin Round

Having been involved with the UK architectural sector for many years, I am fully aware of the challenges professionals face, such as low pay, unpaid overtime, student debts, cost of living, and more. However, I wondered what outsiders thought of the architectural profession. Is it valued or not? There’s only one way to find out.

So, I started asking my friends and family, “How much do you think an architect earns in the UK?” To my surprise, the usual response was in the range of around £70k-£80k per year, indicating they perceive it as a valued and well-paid profession.

However, once I told them the truth – that in reality, an architect earns on average £37,000 per year – they nearly fell off their chairs. They looked at me in disbelief and said, “Don’t architects study for seven years? Why are they being paid so little? How is that even possible?”.

It made me wonder: Why do people outside the industry often value the profession more highly than the industry itself? How is there such a gap between expectations and reality in salaries? How can we improve or, even better, solve these issues?

From experience, I am aware that many architectural professionals blame the low fee structures and the practice of undercutting each other to win projects. When I posed these questions to my LinkedIn network, it became clear that low fees were only the tip of the iceberg.

Modern procurement routes limit the architect’s role, university courses focus too much on conceptual design rather than teaching project management and construction, and senior staff resist adopting agile methodologies and new technology. All this alongside grueling long hours and practices offering to do free work.

The fact that Part 1s are being paid close to the National Minimum Wage, combined with the rising cost of living and increasing student fees, is mind-boggling to me

Adding to the pile of unrealistic deadlines, poor management, increasing workload, and unpaid overtime, it’s evident that the ones who suffer through these poor decisions are the employees.

When staff want to prioritise a healthy work-life balance, it is seen as laziness and a lack of passion. Staying late is considered a badge of honour. This couldn’t be further from the truth.

In my opinion, if practice owners/directors properly manage incoming workload, submit fee proposals that make a profit, stop doing free work, negotiate realistic deadlines, and don’t guilt-trip their staff into staying late most nights (mostly unpaid overtime due to budget constraints), practices would do far better and could pay their staff higher salaries.

This raises another interesting point: Should universities equip every student in the architectural sector with fundamental business management skills?

Imagine a profession where everyone in a practice understands the basics, from strategic to financial and organisational management skills. Wouldn’t this help to showcase the value everyone brings to a business and demonstrate how even the smallest changes can make a practice more profitable?

>> Also read: Architectural graduates can earn more at McDonald’s. That’s bad for diversity and the profession

This brings me to my next question: Why does the architectural industry not have fee guidelines? As I recently learned, if every practice agrees on a minimum fee percentage, it’s classed as price-fixing and a criminal offense (whoopsie-daisy). Would creating fee guidelines be a step in the right direction?

From discussions with professionals worldwide, I know this is not just a UK problem. With the rising cost of living, registration fees, and stagnating salaries, it makes you wonder when enough is enough, and if we will see real changes happening.

The fact is that there is a lot of misinformation and a lack of transparency, and I anticipate that more people will leave the profession and take on Project Management/Design Manager roles as these offer better salaries. The fact that Part 1s are being paid close to the National Minimum Wage, combined with the rising cost of living and increasing student fees, is mind-boggling to me.

It is clear that the expectation vs reality of the architecture profession are two different stories. Given the increasing cost of studying architecture and the stagnation of salaries, it is becoming increasingly unviable as a career choice and students are not aware of this. To improve the situation for the current and future workforce, we need to raise awareness of the issues and come up with solutions.

Protecting buildings, power plants and bridges with metamaterials

Pioneering research projects have demonstrated how Protecting buildings, power plants and bridges with metamaterials against any possible earthquakes is not a fantasy but a good reality.  Here is CORDIS elaborating on how metamaterials can help.

Protecting buildings, power plants and bridges with metamaterials

Pioneering research projects have demonstrated how metamaterials can be used to protect the built environment against ground-based vibrations.
INDUSTRIAL TECHNOLOGIES

 

We know that earthquakes, caused by disturbances that occur far below the ground due to the movement of tectonic plates, can wreak havoc on the surface. But ground-borne vibrations can also be caused by other sources, including passing cars and trains as well as construction and mining operations. “Depending on the intensity, resonating features and proximity of the source, all these vibrations can have significant impacts on the built environment,” says INSPIRE project coordinator Marianna Loli from Grid Engineers in Greece. “These impacts can range from noise disturbance to life-threatening collapses of buildings and infrastructure, with far-reaching consequences for society and the economy.”

Innovative solutions using metamaterials

The main objective of the INSPIRE project, which was coordinated by the National Technical University of Athens in Greece and supported by the Marie Skłodowska-Curie Actions programme, was to design innovative solutions to better protect the built environment from hazardous ground vibrations. These solutions were developed using metamaterials. “Metamaterials are engineered materials that do not exist in nature but can be manufactured to demonstrate exceptional properties,” explains Loli. “This might include the ability to redirect seismic waves to mitigate structural shaking.” The project built on a growing body of scientific evidence that suggests that metamaterials have the potential to enhance the resilience of buildings, bridges and other critical infrastructure during earthquakes. They might also provide superior noise isolation capabilities, thus improving urban living conditions.

Making use of cutting-edge technologies

New concepts were developed through a pioneering training programme that brought together eight European universities and 11 industry leaders. A total of 15 doctoral researchers were then selected through a highly competitive process, from over 100 candidates from around the world. “Through their 3-year-long PhD programmes, the researchers investigated a wide range of anti-vibration metamaterial concepts,” notes Loli. “These included below-ground constructions to act as shields with dispersive, filtering and waveguiding properties, novel damping devices and passive vibration absorbers, and engineered gravel materials that can protect pipelines.” Other innovations investigated included vibration-control devices customised to optimise the seismic response of bridges, and rail-engineering solutions for controlling train-induced vibration to minimise noise in urban areas. Another researcher looked into acoustic surfaces and dynamic vibration absorbers, tailored for low-frequency sound isolation. In developing their ideas, the researchers made use of cutting-edge technologies such as 3D printing, as well as advanced numerical simulations facilitated by supercomputers. These technologies were employed to optimise designs and demonstrate the effectiveness of the proposed solutions.

Safety and liveability of the built environment

The INSPIRE project successfully showed how metamaterials can be used to enhance the safety and liveability of the built environment. “The feasibility of the proposed designs was demonstrated through advanced analytical simulations and small-scale experimental campaigns,” remarks Loli. The project has also delivered a diverse toolkit of algorithms, numerical methods and processing tools, which can be used by researchers involved in similar projects in the future. Next steps towards market uptake of the solutions include large-scale pilot testing and further optimisation of designs. “End users could be the seismic isolation market, companies that promote R&D in the field of structural protection, public sector departments and construction companies,” says Loli. “We think that INSPIRE’s results can also contribute to improving professional guidelines for seismic design.”

Ancient cities provide key datasets for urban planning, policy and . . .

The key word here is Anthropocene and The Middle East with its antecedent start of civilised life as we know is the region to help in understanding not only all matters of geological and climatic balances on the planet but down-to-earth past and present conflicts in the area. So how come  Ancient cities provide key datasets for urban planning, policy and predictions in the Anthropocene?

Ancient cities provide key datasets for urban planning, policy and predictions in the Anthropocene

Cities play a key role in climate change and biodiversity and are one of the most recognizable features of the Anthropocene. They also accelerate innovation and shape social networks, while perpetuating and intensifying inequalities. Today over half of all humanity lives in cities, a threshold which will rise to nearly 70% by the mid-21st century. Yet despite their importance for the Anthropocene, cities are not a recent phenomenon.

In a new study published in Nature Cities, an interdisciplinary team of authors from the Max Planck Institute of Geoanthropology argue that the history of urbanism provides an important resource for understanding where our contemporary urban challenges come from, as well as how we might begin to address them. The paper highlights the ways in which new methodologies are changing our understanding of past cities and providing a reference for urban societies navigating the intensifying climatic extremes of the 21st century.

These methods range from remote sensing techniques like LiDAR, which are documenting cities in places where urban life was once considered impossible, to biomolecular approaches like isotope analysis, which can provide insights into how cities have shaped different organisms and influenced human mobility and connectivity through time. Meanwhile, the study of sediment cores and can show how cities have placed adaptive pressures on different landscapes and —as they still do today.

As understanding of humanity’s influence on the Earth system grows, urbanism is increasingly considered one of the most impactful forms of land use. In this new study, the authors also highlight how multidisciplinary approaches, including Earth system modeling, are revealing the impacts that ancient and historical forms of urbanism had on land use, and, critically, how they compare to the impacts of urban areas today.

Throughout the paper, the authors emphasize that the past does not just provide anecdotal insights, but rather numerical datasets of things like road lengths, building types, population sizes, , environmental impacts, and more. With advances in computational archaeology, this opens up the possibility of quantifying similarities and differences in urban pathways across space and time, directly linking the past to the present.

By reviewing diverse examples from around the world ranging from medieval Constantinople (now Istanbul) to 9th century Baghdad, from Great Zimbabwe to Greater Angkor in Cambodia, this new study highlights the potential of new methodological approaches to reveal historical legacies and predict trajectories of urbanism in the Anthropocene epoch.

 

Unlocking more sustainable futures with green chemistry

Unlocking more sustainable futures with green chemistry is an article that was researched and written by Isabel Williams, a former Masters Student at Oxford University’s Department of Biology.
But achieving SDGs by generalising what is proposed remains to be seen.

Using chemistry to help reach sustainability goals is becoming an increasingly attractive research area. From solving global plastic pollution to improving the performance of rechargeable batteries found in electric cars, ‘green chemistry’ is a truly promising topic.

This article was researched and written by Isabel Williams, a former Masters Student at Oxford University’s Department of Biology.

Tackling the plastic pollution problem

We are all too aware of the global plastic problem. Plastics are unsustainably produced, made, and disposed of, with the material found in the ocean, in landfills, on beaches, and even in the Antarctic. Researchers at the University of Oxford are applying innovative techniques to help tackle this problem.

But why is plastic such a problematic material? To find out why and to begin to tackle these problems, one needs to look at the material’s chemistry.

Plastics are made from synthetic ‘polymers’. Polymers are made from small molecular building blocks, called ‘monomers’, forming a large molecule resembling beads on a string. In plastics, these monomers are usually derived from non-renewable sources such as petrochemicals, making the production of plastic polymers highly unsustainable since they rely on fossil fuels. Additionally, due to the strong bonds between their monomers, synthetic polymers can persist and pollute the environment for hundreds of years before breaking down.

The solution: replacing plastics with ‘greener’ polymers

Whilst efforts to reduce plastic usage and increase recycling can go a long way, it is unlikely that we can eliminate plastics entirely, particularly for uses that have food safety or human hygiene concerns. Many everyday items contain plastic polymers – including shopping bags, paint, electric car batteries, clothing, teabags, and takeaway coffee cups. But if we are not able to completely eliminate plastics, can they be replaced with a greener, more sustainable version?

Researchers at the University of Oxford’s Department of Chemistry are utilising a green chemistry approach to tackle plastic pollution. The aim? To phase out existing polymers and plastics and replace them with greener, more sustainable alternatives.

One avenue being explored is the production of polymers from renewable, bio-derived materials, rather than petrochemicals. Dr Matilde Concilio, a Postdoctoral Research Associate in Professor Charlotte Williams’ laboratory, works on making bio-derived polymers from commercially available resources. By using chemicals already commercialised, safety-checked, and approved, the hope is that any products or processes developed in this way will be swiftly accepted and adopted by industry. With bio-derived plastics accounting for only 1.5% of global plastic production in 2021, there is enormous potential for these materials to upscale and ultimately replace their less-sustainable competitors.

I’m convinced that polymers are the future, but only if you do it in a sustainable way.

 

Dr Matilde Concilio, Department of Chemistry

Dr Concilio’s bio-derived polymers are not only made from renewable sources but are also more sustainable from a processing standpoint. Usually, monomers need to be purified many times to achieve a high-quality final product. This is both energetically costly and expensive.

‘So, to make it more sustainable, what I’m trying to do is use monomers that don’t need to be purified’ Dr Concilio explains. This way, less energy, time, and money are spent on the polymerisation process.

Key to the development and uptake of these new polymers is ensuring that their material properties are as good as, if not better than, current petrochemically-derived options. This is essential if these new materials are to be adopted at scale within plastics industries.

Ultimately, what we want to do is phase out [the current plastics], so that our plastics, which we’re quite heavily reliant on as a society, come from renewable sources.

 

Dr Gregory Sulley, Department of Chemistry

‘One of the main targets for us is to try and property-match to the incumbent materials,’ says Dr Gregory Sulley, another Postdoctoral Research Associate in Professor Charlotte Williams’ laboratory. ‘Ultimately, what we want to do is phase out [the current plastics], so that our plastics, which we are quite heavily reliant on as a society, come from renewable sources.’

With continued work and collaboration, hopefully, sustainable plastics will go on to replace their more unsustainable alternatives, making plastic pollution a problem of the past. With any luck, the sight of plastic in our landfills, oceans, and beaches will soon be a distant memory.

Tailor-made polymers for energy storage solutions:

Similar green chemistry approaches are being applied to solve problems in energy storage. For instance, rechargeable batteries require their components to be in contact with one another to function. However, this is complicated by the fact that some of the components change volume as the battery is charged and discharged. With these batteries used in electric cars, solar panels, and wind turbines, overcoming this problem is a huge priority to help reach Net Zero emission targets.

So, how do you solve this problem? Enter polymers.

Dr Georgina Gregory, a Royal Society Dorothy Hodgkin Fellow, also works on bio-derived polymers. Dr Gregory was formerly a Postdoctoral Research Associate in Professor Charlotte Williams’ laboratory, like Dr Concilio and Dr Sulley, but now has progressed to lead a lab group of her own. What unites these three researchers, other than their shared history with the ‘Polymer Magician’ Professor Williams, is their ability to produce bespoke polymers designed for a specific application.

This application-driven design is integral to Dr Gregory’s work to improve the design of polymers so that they can overcome the current limitations of rechargeable batteries.

‘The polymer, in some respects, comes in as a way of holding it all together’ Dr Gregory explains. This means the polymer needs to be:

  1. Adhesive: to stick everything together in the battery;
  2. Slightly flexible: to accommodate the changes in volume;
  3. Ionically conductive: the polymer needs to allow ions (electrically charged atoms) to flow through the battery.

With these three properties in mind, the researchers set out to precisely design a polymer for use in batteries. By specifically selecting building blocks possessing these properties, and utilising their ability to tightly control the polymerisation process, they were able to tailor the product to the problem.
