This form of energy has been used by humans for thousands of … Biomass energy is a relatively clean, renewable energy source involving the use of organic matter which collected energy from the Sun and converted it into chemical energy when it was alive. Disadvantages of Biomass Energy. Various Advantages and Disadvantages of Biomass Energy Biomass occurs in the form of living or recently living plants and waste. Is Not Very Efficient Compared To Fossil Fuels. Expensive; Though, biomass energy is relatively cheap, its processing to usable forms is quite expensive. 1. Most biomass energy is sourced from plants which have gathered energy from the Sun through the process of photosynthesis. natural organic matter that can be burned directly or converted to other forms of fuel and is used often for lighting For instance, biomass energy requires more workers for the planting and harvesting of the crops resulting to additional expenses.
