Russia: "The most promising way of getting energy in future is from the earth’s interior (geothermal energy)"

Drilling for promising renewable energy sources to cost $30 mln, says expert (TASS)

Drilling a well 10 kilometers deep for geothermal power plants, which are viewed as promising renewable energy sources for the future, is estimated to come to about 2 bln rubles ($30.6 mln), Russian Academy of Sciences Member Sergei Alekseenko said at a TASS press conference on Tuesday.

"The most promising way of getting energy in future is from the earth’s interior (geothermal energy). However, there is one problem - the drilling price. If we build a geothermal plant, then [drilling to the depth] of 10 km, for example, costs about 2 bln rubles ($30.6 mln). If you miss the mark and drill to an improper point, then you will lose that 2 bln rubles. So, scientific engineering studies and new drilling methods are needed here," the researcher stressed.

"Solar energy and definitely geothermal energy are among the most promising areas in this sphere. Not thermal pools that are small in numbers but namely the heat of the deep layers of the earth. The latter area should be invested in heavily by now," Alekseenko said.
