I prefer Nobel price scientists, physicists among them, as compared to what Gov can say.
Soalr is good up to and below 200°F, afterwards costs climb exponentially. How does one transport some heat at any distance ?
Heating homes above the 45° parallel, in winter is a no winner as the sun is hardly above the horizon even at noon and the cross section of atmosphere is damaging. Solar house heating in non economical, and won't be, unless you get fuel around 100$/barrel,and steady.
Projections of the cost per Kw of windfarms will stay high and above that of Nuke even twenty years from now, (and counting the cost of dismantling the nuke plants every forty years or so). Geothermal is a few miles form the source, maximum. Waste burning and recycling is a "hobby", if one considers the total energy balance involved.
Coal, oil, gas, candels and uranium, that what we are stuck with. In our lifetime at least. So make your choice : invest in NE Alaska. |
