Geothermal Energy—Clean Power from the Earth's Heat

By Groat, Charles G.

Description
Excerpt: Foreword: One of the greatest challenges of the 21st century is the production of sufficient energy to power the economies of both the developed and developing world. Fossil fuels—coal, oil, and natural gas—will continue to supply most energy through at least the first half of the century. However, declining reserves of fossil fuels, increased demand, and environmental constraints will challenge human ingenuity in providing alternative sources of energy. Alternative technologies that employ the Sun’s energy (solar-electric and wind power) are advancing rapidly and provide electrical power at costs that are approaching those of conventional technologies.
