Trends in the Development and Utilization of Geothermal Energy for Electricity

Abstract

Worldwide, the electric energy industry is undergoing major changes.

Increasing populations and increased per capita consumption of electricity are straining the power generation capabilities of many countries. Shortages of traditional fossil fuels, or at least permanent price rises in those fuels, are forecast beginning in the near future. Already this is affecting some developing countries. A growing concern for our environment is limiting the use of certain hydrocarbon, nuclear and even hydro fuels. Economists ponder the impact of these factors both on national economies and on the quality of individual life.

One result of this situation has been a renewed interest in the non-traditional fuels, the so-called green or renewable energy. This paper briefly examines five trends that have emerged in recent years relative to the development and utilization of geothermal electricity, and offers a provisional estimate of their significance.
