Tämä on 74219841498. kerta kun sanon sen täällä: Geotermisella energialla saadaan niin paljon sähköä kuin vain ikinä tarvitaan.
Ei muuta.
http://physics.ucsd.edu/do-the-math/2012/01/warm-and-fuzzy-on-geothermal/Clearly, geothermal energy works well in select locations (geological hotspots). But it’s too puny to provide a significant share of our electricity, and direct thermal use requires substantial underground volumes/areas to mitigate depletion. All this on top of requirements to place lots of tubing infrastructure kilometers deep in the rock (do I hear EROEI whimpering?). Even dropping concerns about depletion, the practical/economic challenges do not favor extraction of geothermal heat on a large scale. So geothermal is not giving me that warm, fuzzy feeling I seek. It’s certainly not riding to the rescue of the imminent liquid fuels crunch.
