New international research has found that rooftop solar could meet around two-thirds of global electricity demand.

According to the study, a theoretical maximum of 19,500 TWh of electricity could be generated by rooftop photovoltaics (RPV) each year if every suitable roof was equipped with solar. Combined with load shifting and battery-electric storage, this would be enough to meet 65 per cent of current global electricity consumption.
