It's impossible to give a definitive answer to that question. Have we invested in geothermic research? Yes. Do we have programs which partially promote it? Yes. Why have governments over the years not invested more in geothermics? I think it's due to history and to market conditions. It's a combination of all these elements.
I agree with your basic principle that this type of energy has potential. It's certainly a message we will remember and I will convey it to Mr. Lang.
