geothermal energy

Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The Geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%).[1][2] The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. The adjective geothermal originates from the Greek roots Î³Î· (ge), meaning earth, and Î¸ÎµÏÎ¼Î¿Ï (thermos), meaning hot.

A recent study of gargantuan proportions estimated that the technical potential of photovoltaic cells and concentrated solar power (CSP) in the United States, at today’s level of research and with today’s possibilities, is enough to generate about 400,000 TWh of energy annually, significantly more than any other renewable energy source. The study The National Energy [...]

Iceland is definitely one weird country; it is extremely rich in geothermal and volcanic energy, and has access to a significant quantity of fish, but other than that, resources are extremely scarce. At the end of 2008, the economy collapsed, with all major banks going bankrupt. Since then, they have been desperately trying to rise [...]
