Solar power is attractive because it is plentiful but there are many problems to be overcome before it can power the world. This project is dedicated to reporting progress but
Conservation and efficiency is the answer, at least until an affordable
photovoltaic cell is developed. If Arizona was covered with 10% efficient solar
panels, it could provide the 100 quadrillion BTUs that the USA uses every year.

The race is not over however! See Pyron Solar Power and a new World Record of 40% efficiency has been established in USA also ENECO Solar who claim 38%. Possibly the cheapness of Nanosolar printed foils may outway the efficiency of other products.
Systems in which the sun heats water to generate electricity are developing fast by the Spanish company Acciona Energy and they now plan a 200 MW plant in Nevada which will pay for itself in 10 years.
One of the major problems is that heavy night demand does not co-incide with day time supply (see Electricity Stored ). This is overcome in George Monbiot's thinking of a direct current supergrid which covers several time zones and blends wind power and solar with some storage capacity.
