Environmental Impact of Energy Communities

Energy communities are no longer a futuristic concept - they're already transforming our environmental impact today. Across Europe, citizens are organizing to produce and share renewable energy, creating a movement that's changing both our relationship with the environment and with energy itself.

🌍 Measurable Environmental Transformation

In 2024, the development of energy communities across Europe demonstrates their concrete environmental effectiveness. Spain now counts 556 communities (+44% in one year), Belgium mobilizes €445 million in citizen investments for offshore wind, and France develops 385 community solar installations. These numbers aren't just statistics - they represent thousands of tons of CO₂ avoided each year.

Direct Environmental Benefits

Each MWh produced by an energy community avoids the emission of 440 to 960 kg of CO₂ compared to fossil fuels. To put this in perspective, an average family joining an energy community reduces their carbon footprint by 1.3 to 3.8 tons of CO₂ per year - equivalent to taking a car off the road for 5,000 to 15,000 kilometers.

But the impact goes far beyond simple energy substitution. Energy communities also eliminate transmission losses that represent 7 to 10% of electricity in centralized grids. When solar panels on a roof directly power neighboring houses, this energy travels just a few meters instead of hundreds of kilometers.

⚡ WeSmart: Supporting Green Technology Solutions

WeSmart develops digital tools that help these communities measure and optimize their environmental impact. Our digital platform for energy communities supports groups of motivated citizens in creating true virtual power plants, optimizing production, consumption, and energy sharing in real time.

The LECaaS Project: Innovation for the Environment

As part of our research programs, our LECaaS (Local Energy Communities as a Service) project, developed in partnership with the University of Mons and Multitel, contributes to improving the environmental efficiency of energy communities. This platform uses digital twins and artificial intelligence to:

• Optimize self-consumption: Maximize local use of produced energy, reducing transport needs
• Predict and smooth demand: Avoid consumption peaks that require polluting backup plants
• Integrate smart storage: Coordinate batteries and electric vehicles to stabilize the grid
• Simulate impacts: Virtually test different scenarios before deployment to maximize environmental benefits

Concrete Results in the Field

Our solutions deployed in European energy communities help achieve 23 to 55% reductions in consumption peaks, depending on urban density. This optimization helps avoid reliance on "peaker plants" - inefficient and polluting gas turbines that only operate during high-demand hours.

🔌 Grid Benefits: Less Investment, More Efficiency

Significant Infrastructure Savings

Energy communities generate considerable investment savings for grid operators. When consumption peaks drop by 23 to 55%, utilities can defer or cancel costly investments:

• No need for new high-voltage lines (cost: €1-3 million/km)
• Deferred transformer upgrades (€500,000 to €2 million per substation)
• Avoided distribution network reinforcements

A single 100-household community can avoid €500,000 to €1 million in grid investment over 10 years.

Enhanced Grid Stability

Our technologies integrate advanced grid services that enhance stability:

• Frequency regulation: Community batteries respond in milliseconds to imbalances
• Voltage support: Smart inverters maintain electrical quality
• Islanding capability: Microgrids continue operating even during general outages

These services, traditionally provided by expensive fossil fuel plants, are now delivered by decentralized renewable installations.

🔋 Beyond CO₂: A Global Environmental Impact

Water Resource Preservation

Community renewable energy consumes less than 1 liter of water per MWh (only for panel cleaning), compared to 500 to 800 liters per MWh for coal and gas plants. This difference becomes crucial in the context of growing water stress.

Air Quality Improvement

Each renewable kWh eliminates local emissions of fine particles, nitrogen oxides, and sulfur that poison urban air. The WHO estimates that 99% of the global population breathes insufficient quality air - energy communities directly contribute to improving this situation.

Biodiversity and Territories

Unlike centralized energy infrastructure that fragments ecosystems, community installations integrate harmoniously into territories. Agrivoltaics, for example, combines electricity production and agriculture, sometimes even creating favorable conditions for crops through partial shading.

🚨 Lessons from the April 2025 Iberian Blackout

On April 28, 2025, 60 million people in Spain and Portugal lost electricity for up to 16 hours. This historic blackout revealed the weaknesses of centralized grids facing energy transition, but also the crucial importance of energy communities for resilience.

Why Energy Communities Would Have Made the Difference

Technical analysis of the blackout shows that grid-forming inverters and distributed storage - standard technologies in modern energy communities - could have prevented or limited the outage. Microgrids with islanding capability allow communities to continue functioning even when the main grid collapses.

WeSmart integrates these resilience technologies into its energy management solutions, helping to create energy communities that don't just reduce emissions, but also strengthen territorial energy security.

🌱 Examples of Successful Energy Communities

Belgium: Eeklo, Energy Autonomy Model

This municipality of 21,500 inhabitants generates 130% of its electricity needs through its community wind turbines, operated with tools similar to our Nexgen platform. Result: bills 40% cheaper and 61,000 tons of CO₂ avoided per year. The social innovation? 750 vulnerable households own pre-financed shares, transforming energy transition into a tool for social justice.

France: Village Power Plants

This network of 385 solar installations spread across 59 municipalities produces 7 GWh per year thanks to €12 million in citizen investments. These projects, managed with digital solutions similar to ours, demonstrate that a centralized platform can effectively coordinate hundreds of distributed installations.

Spain: Som Energia, Cooperative Giant

With its 85,000 members, this cooperative avoids hundreds of thousands of tons of CO₂ annually while proving that an energy company can be democratic (one member = one vote) and accessible (€100 social share). Their model inspires our solutions for large groups.

Pilot Project: Le Cailar (France)

In partnership with Sween, we're deploying our first complete French energy community in Le Cailar, with real-time data acquisition and intelligent energy flow optimization.

🚀 The Future with WeSmart: Supporting Environmental Impact

Our approach at WeSmart is pragmatic: help energy communities develop efficiently. Our digital tools help eliminate the technical barriers that historically limited these initiatives to technology pioneers.

Our "as a Service" Platform

Rather than forcing each community to reinvent the wheel, WeSmart offers a suite of standardized tools but customizable:

• Energy simulation and optimization
• Automated flow management
• Billing and benefit distribution
• Intuitive citizen interface
• Real-time environmental monitoring

Measure to Progress

Our dashboards allow members to track in real time their personal and collective environmental impact. Concretely seeing the tons of CO₂ avoided, liters of water saved, and reduction in energy bills creates a virtuous circle of citizen engagement.

🎯 Significant Transformation Potential

Current European energy communities still represent only a fraction of their potential. If 20% of Europeans joined such initiatives by 2030, we could avoid 6.4 million tons of CO₂ per year - equivalent to removing 25.6 million cars from circulation.

WeSmart supports this transition by making the creation and management of energy communities more accessible. Our mission: enable every European citizen to actively contribute to our continent's decarbonization, while reducing their bills and strengthening their territory's resilience. Grid benefits represent an important dividend: every euro invested in energy communities avoids €3 to €5 in traditional grid investments, creating a positive spiral where energy transition rhymes with infrastructure savings.

The environmental impact of energy communities is no longer a promise - it's a measurable reality that WeSmart helps optimize every day. Because the energy transition will be citizen-led or it won't happen at all.
