The U.S. Department of Energy''s Office of Energy Efficiency and Renewable Energy (EERE) has three core divisions: Renewable Energy, Sustainable Transportation and Fuels, and Buildings and Industry. The Renewable Energy pillar comprises four technology offices: Geothermal Technologies Office. Solar Energy Technologies Office.
In addition, the carbon footprint of a geothermal power plant is low. While there is some pollution associated with geothermal energy, this is relatively minimal when compared to fossil fuels. 2. Renewable. Geothermal energy is a source of renewable energy that will last until the Earth is destroyed by the sun in around 5 billion years.
In contrast, renewable energy sources accounted for nearly 20 percent of global energy consumption at the beginning of the 21st century, largely from traditional uses of biomass such as wood for heating and cooking 2015 about 16 percent of the world''s total electricity came from large hydroelectric power plants, whereas other types of …
Renewable energy actually is the cheapest power option in most parts of the world today. Prices for renewable energy technologies are dropping rapidly. The cost of electricity from solar power ...
Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly ...
The future of geothermal energy. Geothermal energy has the potential to play a significant role in moving the United States (and other regions of the world) toward a cleaner, more sustainable energy system. It is one of the few renewable energy technologies that can supply continuous, baseload power.
Geothermal energy is heat that is generated within Earth. (Geo means "earth," and thermal means "heat" in Greek.)It is a renewable resource that can be harvested for human use. About 2,900 kilometers (1,800 miles) below Earth''s crust, or surface, is the hottest part of our planet: the core.A small portion of the core''s heat comes …
4 min read. Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth''s internal heat. This …
"Geothermal is a triple resource: an energy source for heating, cooling, and power; a storage resource; and a mineral resource," said Amanda Kolker, geothermal laboratory program manager at the National Renewable Energy Laboratory (NREL). "The Earth itself has the potential to address a variety of hurdles in the transition to a clean ...

Geothermal energy is considered to be sustainable because the heat extracted is so small compared to the Earth''s heat content, which is approximately 100 billion times 2010 worldwide annual energy consumption. Earth''s heat flows are not in equilibrium; the planet is cooling on geologic timescales. Anthropic heat extraction typically does not accelerate the cooling process.
