Forests have been providing us with energy since the beginning of time. For thousands of years, Man used wood from the trees of the forests for cooking and heating. Coal that is used for burning also comes from our forests, for coal is actually ancient forests that have decomposed under enormous pressure through the ages.
Forest are an important source of bio-energy. Bio-energy is energy, such as electrical or thermal energy, produced using biomass or organic matter. The main sources of biomass are wastes from crops, natural and plantation forests. Biomass power plant burn wood wastes from sawmills and logging operations to generate electricity.
Unlike oil, coal and gas, bio-energy is a renewable energy made out of biological material that can be harvested gain and again.
