in my opinion the issue we have isnt generating electricity but storing it. The methods we use at the moment are incredibly wasteful and inefficient, I truly believe that the only way out of this mess we are in energy wise, is to move away from fossil fuels all together and to move onto something along the lines of the Hydrogen fuel cell. Its clean and cheap to run, the only issue is that the demand for it isnt big enough for there to be a market shift.
We have the technology already, the Honda Clarity is already in existence, it runs completely on Hydrogen slush, the only byproduct is WATER. the issue is that the hydrogen is made at the moment with electricity generated by coal fired power stations. we should be pumping every available penny into this technology and better ways to turn sporadic production (Wind, Wave, Hydro electric) into usable energy (i would say use this to produce hydrogen slush which can then be stored until needed, pretty efficient huh?)
Just my 2 cents
