Energy originates from many resources, including fossil fuels and renewables. It’s crucial to know the difference between different energy sources, mainly because at some point fossil fuels will go out, and some other source of energy will have to replace them. The good news is that many different types of renewable and alternative energies exist, and the most have the potential to provide a cleaner replacement for fossil fuels.

Renewable energy sources replenish at a rate faster than they are used, and are regularly available. For example solar energy, the wind energy, geothermal energy, and biomass.

Solar powered energy harvests the Sun’s sun rays using collector panels, creating electricity in a process that requires both an actual and chemical reaction. Solar power vegetation may consist of a single rooftop to a significant solar farmville farm in the desert. Many homes use pv systems to generate hot water and supplement their electricity. Geothermal energy comes from the heat of Earth’s core, generating steam that hard drives turbines at ability stations. Biomass is a alternative energy source that uses living or just lately useless organic substances to generate electrical power, heat, and fuel. This is often done by growing dedicated vegetation or through the use of agricultural plant residues and other waste avenues. Lastly, marine energy systems like influx and tidal generators take advantage of the power of the sea to generate electric power at a dam or near the jaws of large bodies of water.

The problem with these and other nonrenewable energy sources is that they sometimes cause harm to the environment or people health. The burning of Canada’s boreal forest for the purpose of oil exploration is a crystal clear example; and coal and oil burning releases green house gases that contribute to climatic change. The good news is that a mix of renewable and alternative energy sources could substitute fossil fuels, which includes nuclear vitality, biofuels, and carbon-emission-free hydrogen fuel cells.
