The sun.
Fossil fuels, dams, and windmills all tap into different sources of energy that ultimately come from the sun. Fossil fuels come from the remains of plants and animals that have been dead and fossilized for millions of years. The energy from the sun that was used to create these fossils is now being released as we burn fossil fuels.
Dams store energy from the sun in the form of water. When the water is released, it can be used to generate electricity. Windmills harness the energy of the sun in the form of wind. The wind turns the blades of the windmill, which in turn generates electricity.

Q: What is the ultimate source of energy from fossil fuels?
A: Fossil fuels are formed from the remains of living organisms. Over millions of years, these remains are subjected to heat and pressure, which transforms them into fossil fuels. The energy in fossil fuels comes from the sun. Plants use sunlight to convert carbon dioxide and water into the chemical energy that they need to grow. When animals eat plants, they convert some of that chemical energy into heat and mechanical energy. When fossil fuels are burned, they release the heat and mechanical energy that was originally stored in them.
