A Wind blows across a hill, has done since time inmomorial, that wind is part of the global weather system, so someone comes along and builds a wind farm on the hill, most of the energy is removed from the wind, what effect does that have on the global weather system?
Wave power, many years ago it was demonstrated that wave farms caused or increased costal erosion at a point some distance from the “farm”.
Geothermal, taking heat from the earths crust, what will be the long term effect of this accelerated cooling?
Solar, the production cost of photovoltaic cells has been questioned elswhere but what about heat extraction. placing large solar powered boilers in the desert may seem like a good idea but what are the effects on the flora, fauna and geology of removing that heat source?
maybe the sun will go out before the effects are apreciable but has anyone ever done any reasearch in to the down side of “green” energy?
