There are many ways to reduce your carbon footprint. You can buy an electric car, install solar panels, replace your heating system with a heat pump, use less energy, drive less or simply consume less.
Some of these can make a big difference, but they can also cost a lot of money. Electric vehicles can substantially reduce lifecycle emissions compared with combustion-engine cars, but buying a new car is still a major financial commitment. The IEA compares EV lifecycle emissions here.
Rooftop solar can reduce the emissions connected with the electricity you use, but it normally requires a suitable roof, an installer, electrical work and local approvals. Renters and people living in apartments may not have access to their own roof at all. The U.S. Department of Energy explains the practical requirements for rooftop solar.
Heat pumps can also cut household energy use and emissions. The IEA says modern heat pumps can be three to five times more energy efficient than natural-gas boilers, but installing one is still a significant home improvement. Read the IEA heat-pump guidance.
Other changes cost little or nothing. Driving less, walking or cycling more, reducing food waste and using less energy can all lower emissions while often saving money. The EPA lists practical low-cost actions individuals can take. These are sensible things to do wherever possible.
What if reducing your carbon footprint could also earn you money?
This is where Sunbucks is different. Instead of simply spending money to reduce or offset your carbon footprint, you can buy an individually identified solar cell from just €2. The cell forms part of a real operating solar installation and can be rented back to Sunbucks under a rental agreement.
While your solar cell contributes to renewable electricity generation, you also earn rental fees from it. Your rental begins accumulating in your Sunbucks dashboard from the moment you purchase the cell, according to the rental agreement. To understand the model in more detail, see The Sunbucks Solar Cell Rental Model.
So Sunbucks gives you the opportunity to support lower-carbon electricity generation while earning rental income at the same time. That is the win-win.
The solar project is already operating
Sunbucks does not crowdfund future solar installations. The project is funded, built and brought into operation before selected solar cells are made available on the platform. The distinction is explained in Is Sunbucks.com Legitimate?.
You are therefore not paying into a proposed project and waiting for it to be constructed. You are buying an identified solar cell associated with an operating renewable-energy installation. If you want the simple technical explanation of what you actually own, read What Is a Solar Cell?.
There is also no large minimum purchase. You can start with one solar cell from €2 and add more over time whenever you choose, subject to availability. This also makes solar participation possible for people who cannot install panels themselves; see Can I Earn Money from Solar Without a Roof?.
How many Sunbucks cells could offset my carbon footprint?
In our earlier article, Individual Carbon Footprint: How Solar Cells Can Create a Lifetime Offset, we used an estimated impact of approximately 9.5 kg CO₂e avoided per Sunbucks solar cell per year, based on the published project assumptions used in that article.
Using the same country comparison and average annual CO₂ emissions per person, the approximate number of Sunbucks solar cells needed to match those annual emissions would look like this. For broader country emissions data, see Our World in Data - CO₂ emissions per capita.
| Country | CO₂ per person/year | Approx. Sunbucks cells |
|---|---|---|
| Canada | 14.87 tons | 1,565 |
| Australia | 14.43 tons | 1,519 |
| United States | 13.59 tons | 1,431 |
| Germany | 7.03 tons | 740 |
| Netherlands | 6.84 tons | 720 |
| Ireland | 6.47 tons | 681 |
| Italy | 5.10 tons | 537 |
| Spain | 4.75 tons | 500 |
| United Kingdom | 4.25 tons | 447 |
| France | 4.12 t | 434 |
These are approximate calculations based on national average emissions and the Sunbucks estimate used in the earlier article. They are not individual carbon audits or certified carbon credits.
The important point is that you do not have to buy hundreds of cells at once. Whether the estimate for your country is around 400 cells or more than 1,500, you can start with one cell for €2 and gradually add more. As your number of cells grows, so does the estimated renewable-energy impact associated with them, while the cells can also continue earning rental fees under the rental agreement.
Reduce your carbon footprint and earn at the same time
Buying an EV, installing rooftop solar or fitting a heat pump can all help reduce emissions, but they usually require a significant financial commitment. Sunbucks offers a much smaller starting point: you can start from €2, participate in real solar generation and earn rental fees from the solar cell you own.
That makes Sunbucks different from simply paying for a carbon offset. You own an identified solar cell associated with renewable-energy generation, and that same cell can provide rental income. The broader idea of opening solar participation to more people is explained in Democratizing Solar.
Of course, Sunbucks should not be an excuse to waste energy. Using less electricity, driving less and reducing unnecessary consumption should always come first. But for emissions that are harder to avoid, solar generation gives you another practical way to act.
So what's the cheapest way to reduce my carbon footprint?
Start with the things that cost nothing: use less energy, waste less and drive less where possible. After that, many of the biggest steps can become expensive. Electric cars, rooftop solar and heat pumps can all cost thousands.
With Sunbucks, you can start with one solar cell from just €2, support real renewable-energy generation and earn rental fees from the same cell at the same time. You can then add more whenever you choose and gradually increase the renewable-energy impact associated with your solar cells.
Help reduce your carbon footprint while earning from the Sun. That is the Sunbucks win-win.
FAQ
What is the cheapest way to reduce my carbon footprint?
Some carbon reductions cost nothing, such as using less energy, driving less and reducing waste. Sunbucks provides another option by allowing you to participate in solar generation from just €2.
Can I earn money while reducing my carbon footprint?
Yes. Sunbucks solar cells can be rented back to Sunbucks under a rental agreement. While the cells participate in renewable-energy generation, you receive rental fees according to that agreement.
How much CO₂ does one Sunbucks solar cell avoid?
The earlier Sunbucks carbon-footprint article used an estimate of approximately 9.5 kg CO₂e avoided per solar cell per year, based on its published project assumptions.
How many Sunbucks cells would I need?
It depends on the emissions associated with your country and lifestyle. Using the earlier country comparison, the examples above range from approximately 434 cells in France to 1,565 cells in Canada.
