Almost all forms of energy that we use come, directly or indirectly, from the sun. Explain how solar energy from the sun is converted into the form in each of the energy source listed below: 1)Fossil fuels: 2)Hydroelectric: 3)Wind:

Fossil Fuels

Photosynthesis is also responsible for all of the fossil fuels on Earth. Scientists estimate that about 3 billion years ago, the first autotrophs evolved in aquatic settings. Sunlight allowed plant life to thrive and evolve. After the autotrophs died, they decomposed and shifted deeper into the Earth, sometimes thousands of meters. This process continued for millions of years.

Under intense pressure and high temperatures, these remains became what we know as fossil fuels. Microorganisms became petroleum, natural gas, and coal.
