You have a better chance of hitting a hole in one, page-8

If some one came to me with a proposal to supply power to my business for the 20 years, but it was only effective for 8 hours a day and dropped dramatically when there was cloud cover and the back system only worked when the wind was blowing, and they had no commercial answer for storage, then I would show them the door. How has such an inadequate system got so much support? We will have to spend a lot of money some day correcting this mistake.
