Step-by-step explanation:
Almost all the energy used on Earth ultimately comes from the Sun. The Sun's energy is captured by plants through photosynthesis, which converts solar energy into chemical energy stored in organic molecules. The organic molecules produced by plants, such as carbohydrates, fats, and proteins, are then consumed by animals, which use the stored energy to fuel their own biological processes.
Fossil fuels, such as coal, oil, and natural gas, are also derived from ancient organic matter that was formed from the remains of plants and animals that lived millions of years ago. These fossil fuels are essentially stored solar energy that can be extracted and burned to release energy in the form of heat and electricity.
So, in short, the energy that powers almost everything on Earth is ultimately derived from the Sun.
