In a report released today World Wildlife Fund (WWF), reporting at The World Future Energy Summit says it's research shows that not only is 100% renewal energy doable worldwide by 2050 but if necessary it could be accomplished using Solar alone.

Abu Dhabi, UAE- A new report released on the sidelines of the World Future Energy Summit here today, shows that even if all electricity is to be generated through renewable energy (RE) sources, and with solar photovoltaics (PV) alone, it would take up only an insignificant amount of total land area, contrary to common perception.

”Research has found that PV power plants provide considerable environmental benefits, including a low carbon footprint and a short energy pay-back time.

Replacing existing grid electricity with PV arrays significantly reduces greenhouse gas and heavy metal emissions as well water usage,” says Lettemieke Mulder, First Solar vice president for Sustainability.

This is important and shows that renewal energy can have a small land footprint.  An increasingly crucial value as the world population increases.
