To put it into a simple form renewable energy is energy that is collected from renewable resources which naturally replenishes such as solar energy, wind energy, hydroelectricity energy. Now hence, all fossil fuels are nonrenewable for example nuclear energy is not considered as a renewable source of energy because in order to make nuclear power uranium is needed and uranium is not replenishable on human scale.
However in this paper we are going to focus mainly on the biomass energy that comes from plants and animals. These natural resources contain stored energy which is absorbed by the plants, the energy absorbed is process known as the photosynthesis. When biomass is consumed the chemical energy in biomass is released as heat, it can be burned directly immediately or converted into liquid biofuels that ultimately burned as fuels. Here are some examples of biomass and their uses for energy:
- Wood processing wastes burned to produce heat within the industries and even to produce electricity.
- Agricultural wastes like I have mentioned earlier they are burned and converted into liquid biofuels.
- Food and wood wastes in garbage also burned to generate electricity in power plants or converted to biogas which eventually can be burned as fuel.
Biomass can be converted into other forms of energy too, but burning is the only way to extract useable forms of energy such as methane gas or transportation fuels like ethanol and biodiesel. Another example is crops like corn and sugar cane grown in places like Brazil, India, and Texas these are fermented to produce fuel ethanol for use in vehicles.
To wrap this up let’s state some of the facts of the importance of the biomass energy. Biomass energy is a clean, renewable, reliable source of replenishable energy that could drastically improve our environment, economy and energy security. Not only that it also generates way less air emission than fossil fuels and reduces the amount of wastes sent to landfills and especially decreases dependency on foreign countries for oil.
