The world in a climate crisis. We need to how we get our power. This means we to end the use of fossil fuels, like oil and gas. The European Space Agency (ESA) has on work that could millions of homes with clean energy. It has approved a three-year project to test huge solar farms in space. ESA engineers hope to energy wirelessly from space into people's homes. Testing will place over three years. An ESA spokesperson said one solar-farm satellite could the same amount of electricity as a power station on Earth. She that the aim is to have many of these giant satellites in orbit. They could cut our use of fossil fuels and energy shortages.

The ESA project is Solaris. The ESA states on its website that it to create "a clean and secure energy future for European citizens". Josef Aschbacher, the director-general of the ESA, told the BBC that solar power from space could of "enormous" help. He said: "We need to into carbon-neutral economies and therefore change the way we energy. We especially need to reduce the fossil fuel part of our energy production." He added: "If you can it from space, and I'm 'if we could,' because we not there yet, this would be absolutely fantastic. It would a lot of problems." The satellites will around 1.7 km long. The International Space Station is 110 m in length.
