PART 1: READING

Read the text carefully then do the activities. Alternative energy encompasses all those things that do not consume fossil fuel. They are widely available and environment friendly. They cause little or almost no pollution. Some examples of alternative energies include solar, wind, biomass, hydro-electric and geothermal energies. In this lecture, we will talk about this last example.

‘Geo’ means Earth and ‘thermal’ means energy. Geothermal energy means energy drawn or harnessed from beneath the earth. It is completely clean and renewable. The earth contains a molten rock called magma. Heat is continuously produced from there. Below, 10,000 meters the temperature is so high, that it can be used to boil water. The boiling water then produces steam which is captured by geothermal heat pumps. The steam turns the turbines which in turn activates generators. Geothermal energy produces no pollution, reduces our alliance on fossil fuels. It also results in significant cost savings as no fuel is required to harness energy from beneath the earth

Geothermal energy can be found anywhere on the earth. Most countries tap this energy to generate electricity, using thermal mass flowmeters, and power millions of homes. The United States produces more Geothermal electricity than any other country in the world.
