Biomass is organic material which has stored sunlight in the form of chemical energy. Biomass fuels include wood, straw, manure, sugarcane and products from agriculture. It is a renewable energy srouce because the energy it contains comes from the sun.
Types of biomass
There are 2 possibilities
1) Growing plants specifically for energy use.
Energy crops or power crops are grown on farms in large quantities. Trees, grasees and other crops such as corn are used for energy. Since crops must be replanted every year, they need a lot of fertilizers, water, pesticides.... Corn provedes most fo the liquid fuel from biomass in the USA
The Biofuels policies pursued by rich countries are pushing millions of people in the developing world into poverty and increasing carbon emission, thereby negating the climate change mitigation program says an Oxfam study.
Quoting world bank estimates, the studies say the price of food has increased by 83% in the last three years, which is disastrous for the world’s poor people. The lives of about 290 million people are immediately threatened because of food crisis and about 100 million people have already fallen into poverty as a result.
About 30 million people across the world have been dragged into poverty in the last three year.
Today’s Biofuels are not solving the climate or fuel crisis but are instead contributing to food insecurity and inflation
