There is a climate crisis. We need to stop using fossil fuels, like oil and gas. The European Space Agency (ESA) has started a project to test giant solar farms in space. The ESA hopes to send energy wirelessly from space into people's homes. A spokesperson said one solar-farm satellite could make the same amount of electricity as a power station. The ESA wants to put many of these farms in orbit. They could cut our use of fossil fuels and end energy shortages.

The ESA project is called Solaris. The ESA wants "a clean and secure energy future". It said solar power from space could be very helpful. It said we needed to become carbon-neutral, and change the way we produce energy. It said we needed to cut the use of fossil fuels. It added that solar farms could "solve a lot of problems". The farms will be around 1.7 km long. This is bigger than the International Space Station, which is 110 m long.
