What Is Energy? Energy is the ability to do work. Solar energy comes from the Sun. It's a silent source of energy, because it makes no sound. There is also energy that comes from wind and water. Did you know that energy can come from people, too?When you pedal a bike, you produce energy. You use your legs to push the pedals. Your energy is transferred to the bike. This shift of power or energy makes the bike move. Now imagine riding your bike to create enough power to run a computer. Some students at one school did just that! They hopped on bikes connected to generators and pedaled in place. Soon they were producing electricity. This energy is needed to run their laptop computers.
