The BIGGEST problem with clean energy

Clean energy is a bogus idea. Because of two factors. 1 3 blade wind mills are for show the Netherlands uses 200+ year old wind mills to stop sinking below the waves and no one uses that to power anything. 2 solar cells are highly toxic to produce and produce as much voltage as 2 water batteries of aluminum and copper (the amps though is low (water battery) unless you use activated carbon). It would be simpler to use sterling engines, spring engines, steam engines using lead batteries, steam engines using solar or even wood, sail powered vehicles, vacuum trams, self pumping trams and depth pressure generating devices.
