Traditional use of biomass is more than its use in modern application.In the developed world biomass is again becoming important for applications such as combined heat and power generation.In addition,biomass energy is gaining significance as a source of clean heat for domestic heating and community heating applications.In fact in countries like Finland.USA and Sweden the per capita biomass energy used is higher than it is in India.China or in Asia.
Geothermal Energy
We live between two great sources of energy,the hot rocks beneath the surface of the earth and the sun in the sky.Our ancestors knew che value of geothermal energy;they bathed and cooked in hot springs.Today we have recognized that this resource has potential for much broader application.
The core of the earth is very hot and it is possible to make use of this geothermal energy.These are areas where there are volcanoes.hot springs,and geysers,and methane under the water in the oceans and seas. n some countries,such as in the USA water is pumped from underground hot water deposits and used to heat peoples houses.
The utilization of geothermal energy for the production of electricity dates back to the early part of the twentieth century.For 50 years the generation of electricity from geothermal energy was confined to Italy and interest in this technology was slow co spread elsewhere.In 1943 the use of geothermal hot water was pioneered in lceland.
