The Electricity Bill That Made Me Think Differently
January 2023, Dublin. Another email from the energy provider. Rates going up. Again.
Paid it. Moved on. As you do.
Then a conversation with a friend from Germany changed things. He mentioned that his town has a solar cooperative — a group of local people who pool money together to install solar panels on public buildings. The cooperative sells the electricity. The members get a share of the profit.
“Wait,” I said. “You can just… invest in solar panels? Like buying a small piece of them?”
“Yes,” he said. “And the government pays extra for green energy. It’s not life-changing money. But it’s something real.”
That conversation sent me researching for weeks. And what I found was surprising: across Europe, normal people — renters, workers, immigrants, people with a few hundred euros saved — are already investing in renewable energy and earning real returns from it.
This article explains exactly how. What the options are, how each one works, how much you can realistically earn, and where to start if you have never invested in anything before.
What Is Small-Scale Renewable Energy Investing?
Renewable energy investing, at the small scale, means putting a relatively small amount of money — sometimes as little as €50 — into a project that generates clean electricity. In return, you receive a share of the income that project produces over time.
The energy itself might come from solar panels on a school rooftop, a wind turbine in a rural area, or a community solar farm. You are not running these projects. You are one of many small investors who helped fund them, and you earn a proportional return while the project generates and sells electricity.
This is different from buying shares in a large energy company on the stock market. In that model, you have no idea what your money is actually financing. With cooperative and crowdfunding investments in renewable energy, you can often see exactly which panels or turbines your money helped build.
The concept is not new in Europe — it has been growing steadily for over a decade — but the digital platforms that make it accessible to beginners are relatively recent, and many people still do not know these options exist.
How Does It Work? The Four Main Models
There are four main ways to participate as a small investor. Each suits a different situation and level of commitment.
1. Energy Cooperatives
An energy cooperative is a group of local people — often in the same town or region — who pool their money to fund a renewable energy project together.
How it works:
- You buy shares in the cooperative, typically €100 to €500 per share
- The cooperative uses that money to build or fund a project — usually solar panels on public buildings, local wind turbines, or community energy systems
- The project sells electricity to the grid or local users
- Profits are distributed to members as dividends, proportional to how many shares you hold
Typical returns: 3–6% per year
Best for: People who want to be part of something local and community-driven, not just a financial return
To find cooperatives in your area, search “energy cooperative” plus your country name. Many have public websites and open membership periods. Some are regional, some are national, and the quality varies — researching the cooperative’s track record before buying shares is important.
2. Rooftop Solar Panels on Your Own Home
If you own your home — or rent with your landlord’s permission — installing solar panels on your roof is one of the most direct forms of renewable energy investment available.
How it works:
- You pay to have solar panels installed on your property
- The panels generate electricity during daylight hours
- You use that electricity yourself, which reduces your bill
- Any electricity your panels generate that you do not use gets sent back to the grid
- Your energy provider pays you for that surplus electricity at a rate called a “feed-in tariff”
- Over time, the combination of lower bills and income from surplus electricity pays back the installation cost and then generates profit
Typical installation cost: €5,000–€10,000 depending on system size and country
Typical returns: 4–7% per year, over a 20-year system lifespan
What the research says: A study across five EU countries — Spain, Italy, Greece, France, and Austria — confirmed that solar panel investments are profitable in all of those locations. Greece came out strongest due to high feed-in tariffs and plentiful sunlight. Austria was the weakest performer due to lower solar yields and fewer government incentives. Southern European locations generally recover their investment in 10–15 years; central European locations typically take 12–18 years.
Best for: Homeowners who can absorb the upfront cost and want a long-term, reliable return
3. Crowdfunding Platforms for Renewable Projects
This is the most accessible option for complete beginners and people without large savings. Crowdfunding platforms let you invest small amounts — sometimes starting at €50 — into specific renewable energy projects across Europe.
How it works:
- You create an account on a crowdfunding platform
- You browse available projects — each listing shows what the project is, where it is located, the expected return, the duration, and the risk level
- You invest your chosen amount into one or more projects
- The project is built and begins generating electricity
- You receive interest payments over the project’s lifetime, typically 3–10 years
- At the end, your original investment is returned
Typical returns: 5–9% per year, depending on project and risk level
Best for: Beginners who want to start small, people who do not own property, and anyone who wants to invest across multiple projects rather than committing to one large outlay

4. Community Wind Projects
Similar to energy cooperatives but focused specifically on wind energy. A community group develops a wind turbine project in their region, and local people can invest to become part-owners.
How it works:
- A community organisation or developer raises funds from local investors (typically €500–€5,000 minimum)
- A wind turbine or small wind farm is built
- The turbine sells electricity, and investors receive a share of the income
Best for: People with a few thousand euros to invest who want a longer-term, larger-scale commitment to a specific project
These are less accessible than crowdfunding platforms and often require more research to find, but they exist across Northern and Western Europe — particularly in Germany, Denmark, the Netherlands, and increasingly in Eastern European countries where renewable capacity is being expanded.
Why It Is Worth Considering
There are several real reasons why small-scale renewable energy investing deserves attention — and a few honest caveats worth knowing upfront.
The returns beat most bank accounts. In an era when European savings accounts offer 1–3% annually (if that), a 5–8% return from a crowdfunding project is meaningfully better. Your money is actually working.
Europe is making this category grow. The EU’s commitment to 45% renewable energy by 2030 is not just a political statement — it means ongoing government support, subsidies, and incentives for renewable projects. This creates a more stable environment for these investments than many other sectors.
The entry point is low. You do not need to be wealthy to start. A €50 or €100 investment in a crowdfunding project is a real way to begin. This makes renewable energy investing accessible to people who have never invested in anything before.
The platforms are regulated. The established platforms operating in Europe are subject to financial regulation in their home countries. Enerfip, for example, is approved by the AMF, the French financial markets authority. This does not eliminate risk, but it provides a level of oversight that informal investments do not have.
It is long-term and relatively predictable. Unlike stock market investments that fluctuate daily, a solar farm project produces electricity at a predictable rate and sells it at a contracted price. The returns are not exciting, but they are more consistent.
The honest caveat: This is not a fast way to make money, and it is not risk-free. Projects can face delays. Regulations can change. Platforms can fail. The appropriate approach is small, diversified positions across multiple projects — not a single large bet.
Step-by-Step: How to Start
Step 1 — Decide Which Model Fits Your Situation
Answer three questions:
Do you own your home? If yes, rooftop solar is worth researching seriously. If you rent, your options are cooperatives, crowdfunding, and community wind.
How much can you invest right now? If it is under €500, crowdfunding platforms are the right starting point. If you have €1,000 or more and want a community connection, look into cooperatives. If you have €5,000+ and a long time horizon, wind projects become an option.
Do you want local involvement or purely financial returns? Cooperatives and community wind projects often have member meetings, local impact reports, and a tangible community connection. Crowdfunding platforms are more transactional — you invest, you wait, you earn. Both are valid; it depends on what matters to you.
Step 2 — Research the Options in Your Country
The availability of options, the level of government support, and the typical returns vary significantly between European countries. Here is a quick
overview:
- Greece and Spain: Strong solar conditions, relatively generous feed-in tariffs, and growing crowdfunding markets make these among the most profitable countries for solar investment
- Italy: A mature market with established platforms like Ener2Crowd and a long tradition of energy cooperatives
- France: Strong crowdfunding sector led by Enerfip, which has been operating since 2014
- Germany: Deep cooperative tradition; some of the most organised community energy structures in Europe
- Netherlands: Mature crowdfunding market with several platforms; strong government support for renewables
- Eastern Europe: Smaller market currently but growing, partly driven by EU investment programmes targeting less developed regions
For your specific country, search for “energy cooperative” or “green energy crowdfunding” plus your country name. Join local Facebook groups or expat forums and ask what others are using — this often surfaces options that are not well-known outside local communities.
Step 3 — Choose a Platform and Browse Projects
For most beginners, the best first step is creating an account on one of the established crowdfunding platforms — Enerfip or Ener2Crowd are good starting points depending on where you are in Europe.
Once inside, look at the available projects. Each listing will show:
- What the project is — a solar farm, a community energy system, an efficiency project
- Where it is located — country and region
- The expected return — expressed as a percentage per year
- The duration — how many years until your money is returned
- The risk rating — the platform’s assessment of how likely the project is to deliver as promised
- How much is already funded — a project that is 90% funded by other investors is generally lower risk than one just starting to raise money
Read two or three project descriptions carefully before deciding anything. The goal at this stage is understanding, not commitment.
Step 4 — Understand the Key Numbers
Before you invest a single euro, make sure you understand these figures for any project you are considering:
Expected annual return: This is the percentage you earn per year. A 6% return on €500 is €30 per year. On €1,000, it is €60.
Project duration: Renewable energy projects typically run for 5 to 20 years. A crowdfunding project might ask you to commit your money for 3 to 7 years. Make sure you are comfortable not having access to that money for that period.
Platform fees: The return advertised is usually before platform fees. Read the fee structure carefully. A 7% return with a 2% annual fee is effectively 5%.
What happens if the project underperforms: Understand what protections exist. Some projects are backed by guarantees from the developer; others are not. The risk rating should reflect this.
Tax obligations: Investment income from these platforms is taxable in most European countries. The platform will usually provide a statement of earnings for tax purposes, but it is your responsibility to declare it. If you are unsure, a quick question to an accountant in your country is worth the cost.
Step 5 — Start Small and Diversify
Your first investment should be small enough that losing it entirely would not hurt you financially. Not because you expect to lose it — established platforms with regulated projects are generally reliable — but because starting small removes the emotional pressure that leads to bad decisions.
Invest €100 or €200 in one project. Wait for the first payment. Understand how the process works in practice. Then, if you are comfortable, add more — ideally across different projects, different technologies, and if possible, different platforms.
A simple diversification approach for a €1,000 total investment:
- €300 in two or three solar projects on Enerfip
- €300 in two or three Italian projects on Ener2Crowd
- €200 in a local cooperative if one is available in your area
- €200 held back to add to whichever performs best after six months
This spreads your risk without requiring you to understand dozens of different projects at once.
Step 6 — Track Your Investments
Keep a simple record. A spreadsheet with these columns is enough:
- Project name and platform
- Amount invested
- Start date
- Expected annual return
- Payment schedule (some pay quarterly, some annually, some at the end)
- Actual payments received
- Date investment is due to be returned
Check it every three months. This keeps you aware of what is performing as expected and what might need attention.
Tips to Do Better and Avoid Costly Mistakes
Mistakes That Catch Beginners Out
Expecting quick returns. Renewable energy projects are built on physical infrastructure. They take time to construct, connect to the grid, and start generating income. A project with a 6% annual return pays that return from the moment it is operational — but that might be six months or a year after you invest. Read the timeline carefully before committing.
Ignoring platform fees. The headline return figure on many platforms is before fees. A 7% return with a 1.5% annual platform fee is effectively 5.5%. This is still good, but the difference matters over several years. Read the full fee structure before investing.
Putting everything into one project. One investor who put €5,000 into a single wind project found that project delayed by two years due to permitting issues. His money was tied up and unavailable for that entire period. Diversification across multiple projects and platforms protects against this kind of single-project risk.
Forgetting about taxes. In most European countries, investment income is taxable. The platforms provide annual earnings statements, but you are responsible for declaring the income. Keep records from the beginning and build the tax obligation into your return calculations.
Not checking whether the platform is regulated. Not all platforms operating in Europe are properly regulated. Before creating an account or depositing money, check whether the platform is authorised by a recognised financial authority in its home country. This information should be clearly stated on their website.
Investing based on green enthusiasm alone. The environmental benefits of these investments are real and meaningful. But financial decisions still need to be based on financial criteria. Evaluate the return, the risk, the duration, and the platform quality — then also feel good about the environmental impact.
Tips to Improve Your Results
Look for government subsidies before investing in home solar. Many European countries and regional governments offer grants, tax credits, or low-interest loans for residential solar installations. These can significantly reduce the upfront cost and improve the overall return. Check your national government’s energy website and your regional authority’s website before getting any solar quotes.
Watch for bonus interest promotions on crowdfunding platforms. Platforms occasionally offer higher rates on new project launches or on projects that are close to their funding target. Signing up for platform emails means you will see these when they appear.
Reinvest your earnings rather than withdrawing. In the early stages especially, the amounts earned per year are small. Keeping that money on the platform and directing it into new projects compounds your returns over time — the same principle as compound interest, but applied to renewable energy returns.
Join the communities around these platforms. Enerfip and Ener2Crowd both have active investor communities — forums, newsletters, and social media groups. These surfaces useful information about project quality, platform updates, and what other investors are experiencing. It is one of the best ways to learn faster.
Think in five-year windows, not months. The returns from renewable energy investing accumulate slowly but steadily. An investor who started with €1,000 at 6% and reinvested all earnings for five years would have approximately €1,338 — a €338 gain without doing anything after the initial investment. The longer the horizon, the more meaningful the compounding becomes.
What the Future Looks Like for Small Investors
The broader context for this type of investing is positive. Europe’s energy transition is accelerating, and small investors are increasingly included in that shift.
The EU is actively promoting “energy communities” — formal structures that allow groups of citizens to invest in, manage, and benefit from renewable energy projects together. These are being supported by regulatory frameworks that make it easier to set them up and easier for individuals to join them.
Crowdfunding platforms are expanding their reach across borders. Enerfip, which started in France, now operates in Spain, Italy, and the Netherlands. As platforms grow and compete, the quality of projects and the terms for investors tend to improve.
The European Investment Bank and major financial institutions are channelling billions into renewable energy infrastructure. Much of this supports the same technologies that small investors are funding through cooperatives and crowdfunding platforms — meaning the overall ecosystem is growing and becoming more stable.
This does not guarantee that any individual investment will perform as expected. But it does suggest that the market for this type of investing in Europe is becoming deeper, more regulated, and more accessible — which benefits small investors who are willing to start learning now.
And Now, What To Do Next?
Renewable energy investing is not a fast income source. It will not replace your salary or fund your retirement in two years.
What it is, for the right person, is a way to put savings to work at returns significantly better than a bank account, in projects you can see and understand, with a real-world impact you can point to.
The starting point is simpler than most people expect. Create an account on Enerfip or Ener2Crowd. Browse the available projects. Invest €100 or €200 in one that makes sense to you. Track what happens over the following months.
That first small investment teaches you more than hours of reading. You learn how the platform works, how payments arrive, what the statements look like, and how it feels to have money working in something concrete.
Then, if it makes sense for your situation, you add more. Slowly. Across multiple projects.
Here is where to begin this week:
- Choose one platform — Enerfip if you are in France, Spain, Italy, or the Netherlands; Ener2Crowd if you are in Italy; search for local cooperatives if you prefer a community model
- Browse five to ten project listings and read the details on at least two of them fully
- Invest a small amount — €50 to €200 — in one project that you understand
- Set a calendar reminder for three months from now to check on it
- Decide then whether to add more
Your money is sitting somewhere right now. The question is whether it is earning anything meaningful while it waits.
