Tiny Pacific Island Becomes The First Completely Solar-Powered Nation

Think a completely renewable-energy-based society is a pipe dream? Tiny Tokelau will no longer rely on imported diesel, instead switching over to solar panels and coconut-based biofuel. Fiji, the Cook Islands, Samoa, and Tuvalu plan to follow suit in the next decade. Voice Of America reports:

The remote islands of Tokelau have become the first territory in the world to be powered by the sun, officials say. The move is expected to save money and ease the environmental burden of relying on imported fossil fuels.

“The Tokelau Renewable Energy Project is a world first. Tokelau’s three main atolls now have enough solar capacity, on average, to meet electricity needs,” said New Zealand’s foreign affairs minister Murray McCully in a statement. “Until now, Tokelau has been 100 percent dependent upon diesel for electricity generation, with heavy economic and environmental costs.”

The island nations of Samoa and Tuvalu are aiming to get all of their electricity from renewable sources by 2020.

Sweet, Sweet Diesel: Sugar Can Be Used to Create Fuel

Looks like we may soon look to sugar as a new fuel source. Think it’ll make your car hyper, too?

Via e! Science News:

A long-abandoned fermentation process once used to turn starch into explosives can be used to produce renewable diesel fuel to replace the fossil fuels now used in transportation, University of California, Berkeley, scientists have discovered. Campus chemists and chemical engineers teamed up to produce diesel fuel from the products of a bacterial fermentation discovered nearly 100 years ago by the first president of Israel, chemist Chaim Weizmann. The retooled process produces a mix of products that contain more energy per gallon than ethanol that is used today in transportation fuels and could be commercialized within 5-10 years.

While the fuel’s cost is still higher than diesel or gasoline made from fossil fuels, the scientists said the process would drastically reduce greenhouse gas emissions from transportation, one of the major contributors to global climate change.
