Alex,
It is not that solar power and wind power are not viable.
It is that both have an efficiency of about 25% and electricity cannot be stored. So when the Sun shines and the Wind blows power is made. Problem is that the grids can take the power but not at peak times in daylight. The grids are handling what these handle and an excess cannot be handled.
So at night the Sun does not shine and generally the wind does not blow.
So if you can figure a way to handle that then you win. Then these will be viable.
Power systems need/require continuity and a thing called turn up and turn down fast. Coal/gas/nuclear/water plants do that.
And that is the problem!
So to have 'environmentalists' get on the file of Solar and Wind is to say they don't have a clue as to how things work.
Nothing wrong with being green. Everything wrong with not knowing what the greenie is talking about. And that is dangerous as most people have no clue. Al Gore anyone?
