Geothermal systems: system types, applicability and environmental impacts

Geothermal energy is often overlooked during discussions of green and sustainable energy sources. But due recent advances in technology and the rising cost of other energy sources, research now shows that geothermal systems may be one of the most cost-effective and environmentally friendly options. This paper discusses the technology of geothermal energy for heating and cooling buildings, its cost advantages, and its environmental effects (positive and negative). Based on research by Bruce L. Cutright.
