Heat and light from the sun are the biggest renewable energy source on our planet. Solar energy is everywhere and we can use it thanks to solar systems, which convert it to electrical and thermal energy, so that we canprovide light and heat to our homes, or get sanitary water. Solar power plants generate electricity, while solar collectors heat space and water. It would be too much, however, to expect from the sun to provide us with free energy all year round. It’s gone at night, when it’s cloudy, and during the winter, so energy has to be collected and stored in collectors and batteries, but these are not inexhaustible either, so we have to have back-up sources, too.
