Earth's Oldest Energy Sources

One of Earth’s oldest energy sources can also be one of the accommodating to our environment. Biomass is any organic or natural substance that is on Earth like wood, crops, agricultural products, landfill gas and biogas, biofuels, animal waste, vegetables, and seaweed. For many years, people have used burned wood to generate their homes and use it to make their food. Biomass gets all its energy from the Sun. All organic substances have stored energy, also known as potential energy, from the Sun. We use biomass to make energy in many different ways. For example there is fermentation, which is the creation of alcohol from a plant but sometimes only taken from the starch. When burning biomass we can convert it from waste-to-energy to make steam
