Can solar be the ultimate energy source on Earth?

Electricity can also be produced directly from sunlight byWhere's my solar power missing? photovoltaic (PV) cells, which use the photoelectric effect. The international space station and most satellites are powered by PV cells. In 2005, Germany & Japan each had approximately 1400 MW of installed PV capacity both off -and on grid. Since 2006, PV electricity in Italy has been cheaper than retail grid electricity at 21.08 €-cents per kWh and costs the same as grid electricity in Hawaii & other islands, where diesel fuel is used for electricity.

Like the wind energy market, the solar energy market too is growing rapidly. According to MARKET BUZZ 2007: Annual World Solar Photovoltaic Industry Report, the 2006 growth rate for PV alone was 19% while installed PV capacity increased 42% in 2005. This will certainly attract additional investment, which will lower solar energy costs. And like wind energy, solar energy produces no pollution and has no adverse environmental effects. Makes one think that British Petroleum was onto something in changing its name to BP, Beyond Petroleum.
