Much of the energy we use today came origanally from the sun.explain?

Answer 1

Plants and many bacteria, use the sunlight to make food. They then eventually go up the food chain to us, and thus we get the energy to move around or even walk. We have to get the energy from these guys because we don'r get our energy from the sun.

Also, pretty much all the things we burn as fuel (gasoline, wood, charcoal, coal, natural gas, etc) originally came from plant sources, which as stated above got their energy from the sun (sometimes millions of years ago). Burning them releases the stored energy.

Answer 2

The sun is the ultimate source of energy for most living organisms and processes on Earth. Solar energy is converted through photosynthesis into chemical energy in plants, which is then consumed by animals. Fossil fuels, such as coal, oil, and natural gas, are also derived from organic matter that originally obtained its energy from the sun millions of years ago.
