German climatologist and geophysicist who, in 1915, published as expanded version of his 1912 book The Origin of Continents and Oceans. This work was one of the first to suggest continental drift and plate tectonics. He suggested that a supercontinent he called Pangaea had existed in the past, broke up starting 200 million years ago, and that the pieces drifted to their present positions.
Geothermal heating system price varies depending on the type of loop system, usually either vertical or horizontal. On average, a typical home of 2500 square feet, with a heating load of 60,000 BTU and a cooling load of 60,000 BTU will cost between $20,000 to $25,000 to install.
Renewable Energy Vermont estimates the cost of the above ground geothermal components at $3,800 to $5,000 per ton of capacity at the time of publication, plus $1,500 to $2,000 per ton for the underground portion of a typical geothermal system.hile geothermal heating and cooling costs several times more than other technologies, these systems pay for themselves in energy savings in 5 to 10 years, according to the U.S. Department of Energy.
