Photovoltaic energy (PV) is the primadonna of renewable energy technology. Currently, it only generates just a small part of total renewable energy supply, less than wind, hydro power or biomass. But it also bears by far the biggest potential - larger than that of all other renewable energy sources, larger than anything to which fossil fuels and nuclear power could ever aspire. Photovoltaics are the most promising of all energy technologies, giving us the best option to overcome global energy crises.
