There's tons of major, <b>major</b> problems with so-called 'renewable' energy sources (I'm no proponent of coal/hydrocarbons, mind you).<br>Solar panels are made of hundreds of extremely toxic materials.  They're toxic to manufacture, and horrible to dispose of because most of those materials cannot efficiently be recovered once the solar cell no longer has the conversion efficiency to be cost effective.<br>Likewise with wind towers - discounting the fact that they're bird-thwacking eye sores nobody wants on their horizons (any more than they want nuclear cooling towers) - by the time they're manufactured, transported, erected, and put into service the energy savings are difficult to recoup because their life spans are no better than current solar panels.<br><br>But things like salt reactors can be made small, safe, efficient, and out of sight - no cooling towers required.  And considerably cheaper than both huge unsightly wind farms, solar farms, and full scale nuclear plants.  Also, if for some reason the cooling (power generation) system should fail there's no runaway reaction... the whole process simply crashes and the molten salt cools into a solid.  Yeah, a radioactive solid, but it's contained, can be safely cordoned off, buried, or even started back up once the failure is repaired (if it can be).<br>Unfortunately the corporate power industry wants to keep that technology out of sight - it's too efficient, creating cheaper energy so they could not fleece everyone as much (though they would certainly try and, in America, succeed).
