It is also critical for the government and other regulatory offices to work with the private sector in the development and introduction of more efficient technology, so that a path can be constructed that slows down and eventually stops the growth in greenhouse gas emissions, while providing a reliable, affordable supply of energy.
Therefore, technology-oriented research and development strategy is essential if a less carbon-intensive future is to be realized.
“Geothermal resources have been known since the dawn of mankind, when
natural hot springs were first used for cooking.” The use of geothermal energy has
recently become increasingly popular due to its many advantages. Geothermal energy
uses earth’s natural energy to heat and cool. There is no emission of pollution. This
system is safe and can replace the conventional methods of heating and cooling. For this
reason, geothermal energy will help keep the earth clean and healthy. “Though the
number of geothermal systems sold today is still less than 1% of the domestic heating
market, sales for fall 1997 through spring 1998 were up nearly 22% from the year
before”. Geothermal energy can also be used to generate electricity, which is so
widely used in our society.
“Electricity is actually generated from geothermal energy by harnessing steam power. Large volumes of thermal water are brought to the surface through production wells, which are drilled into the upwelling plume of the natural hydrothermal convection system. The water is under high pressure since it is coming up from depths of 1 to 4 km. A well 25 cm. in diameter at the bottom can produce 200,000 to 800,000kg/hr of geothermal water and steam. Between five and ten of these production wells, depending on temperature, will generate enough steam for a power plant producing 55MW of electricity, which is typical single-plant size.”
