The sun is a major energy source. We harness this endless solar energy source with solar panels. Studies show that we get more energy from the sun in an hour than the energy used by the world in a year1. 

Solar panels are made from silicon and other materials that can transform sunlight into electricity. They can power homes, schools, and communities. Solar power is an excellent example of sustainable development because it provides safe energy consumption. 

It doesn't release carbon emissions like when we harness energy from fossil fuels. Renewable energy sources don't cause air pollution, thus saving the environment and promoting energy efficiency.
