Investors and players in the energy business often focus on the flashiest technologies, ranging from highly visible solar and wind in the generation sector to next-generation smart meters monitoring usage on the customer level.
Geothermal is often the “forgotten renewable.” While some countries and regions are able to access large-scale geothermal power production, the use of distributed geothermal to regulate temperatures and limit the extremes of air-conditioning or heating use could promote huge efficiencies in energy use across the entire US.
Part of the series of “101″ introductions to energy from the US Department of Energy, this video, like its predecessors, has something to teach even the energy expert for whom geothermal may not be a focus.
For those interested in the basics of solar, check out another video in the DOE “Energy 101″ series on solar photovoltaic technology.
While initial construction costs and hassle for geothermal pipes appear daunting, even in this video intended to promote them, more historical data showing how long it takes for the energy savings to offset the construction costs could promote more widespread installation of geothermal.
Already, some companies are using underground cavities to cool hot air at data centers, and the use of geothermal could spread further to less-obviously energy intensive structures as energy prices rise amid strained supply and ceaseless demand growth.
