How to Power 100 Percent of the World's Electricity by Solar

Renewable Energy

World Wildlife Federation

A new report released on the sidelines of the World Future Energy Summit 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.

The report, Solar PV Atlas: solar power in harmony with nature, shows through seven cases—six countries and one region—less than 1 percent of the total land mass would be required to meet 100 percent of projected electricity demand in 2050, if generating electricity only with solar PV .

World Wildlife Fund (WWF) teamed up with First Solar, 3TIER and Fresh Generation to develop the report. It looks at Indonesia, Madagascar, Mexico, Morocco, South Africa, Turkey and the Indian state of Madhya Pradesh.

The regions represent diverse geographies, demographics, natural environments, economies and political structures. They receive different but good average levels of sunshine, and all show vast potential for widespread development of solar PV, a well-established, commercially available and reliable technology today.

The report illustrates that PV technology, when well-planned, does not conflict with conservation goals and clarifies that no country or region must choose between solar PV and space for humans and nature.

"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 new report supports WWF’s vision of 100 perecent RE by 2050. “We are actively promoting investments and measures in renewable energy technologies that help to make this happen,” according to Jean-Philippe Denruyter, WWF’s manager Global Renewable Energy Policy.

“As climate change increasingly threatens people and the natural world, it is more important than ever to work for the rapid and wide-scale adoption of well sited, responsibly operated renewable energy power facilities. Environmental protection and renewable energy can and are developing in parallel,” says Samantha Smith, leader of the WWF’s Global Climate & Energy Initiative.

On July 8, President Trump hosted a White House event to unabashedly tout his truly abysmal environmental record. The following day, coincidentally, marked the one-year anniversary of Andrew Wheeler at the helm of the U.S. Environmental Protection Agency (EPA), first as acting administrator and then as administrator after the Senate confirmed him in late February.

World hunger is on the rise for the third consecutive year after decades of decline, a new United Nations (UN) report says. The climate crisis ranks alongside conflict as the top cause of food shortages that force more than 821 million people worldwide to experience chronic hunger. That number includes more than 150 million children whose growth is stunted due to a lack of food.

Because extreme heat is one of the deadliest weather hazards we currently face, Union of Concerned Scientist's Killer Heat Report for the U.S. is the most important document I have read. It is a veritable wake up call for all of us. It is timely, eye-opening, transparent and factual and it deals with the stark reality of our future if we do not make changes quickly (think yesterday). It is important to ensure that we all understand it. Here are 10 terms that really help drive home the messages in the heat report and help us understand the ramifications of inaction.

Kyle Rosenblad was hiking a steep mountain on the island of Maui in the summer of 2015 when he noticed a ruggedly beautiful tree species scattered around the landscape. Curious, and wondering what they were, he took some photographs and showed them to a friend. They were Bermuda cedars, a species native to the island of Bermuda, first planted on Maui in the early 1900s.

You may know that many conventional oat cereals contain troubling amounts of the carcinogenic pesticide glyphosate. But another toxic pesticide may be contaminating your kids' breakfast. A new study by the Organic Center shows that almost 60 percent of the non-organic milk sampled contains residues of chlorpyrifos, a pesticide scientists say is unsafe at any concentration.
