Renewable energy is energy from a source that nature maintains in a constant supply over time. In contrast, the supply of fossil sources of energy such as oil, natural gas or coal becomes less and less as these energy sources are used. The sun is a constant natural source of heat and light. Sunlight can be converted to electricity.
Solar energy is energy that comes directly from the sun.
I want more information. Biomass is a source of renewable energy because the natural process of photosynthesis constantly produces new organic matter in the growth of trees and plants. Photosynthesis stores the sun's energy in organic matter. That energy is released when biomass is used to make heat, electricity or liquid fuels. I want more information.
