According to an article at CleanTechnica's website, Google.org, the philanthropic arm of Google, has invested close 10 million dollars into Geothermal. This investment is supposed to help progress the use of Geothermal energy, among other things. Geothermal uses the heat under the earth's surface to spin turbines to create energy (electricity for the grid). Geothermal plants run continuously and if built correctly, seem to be renewable.
If a geothermal plant has a larger capacity than what the geothermal location can supply eventually the geothermal plant's energy production capacity will decrease. Eventually if things are unchanged the geothermal plant can cease to produce energy due to the geothermal location not being able to replenish the heat within geothermal formation. If, however, the plant lowers it's production levels or stop operating for a time it is possible for the geothermal formation to replenish itself.
With the attention and funding from a company like Google, geothermal energy might be given a little extra boost. Geothermal is a promising resource that if used correctly could offer many lasting benefits.
