Tokelau, a small island nation, is officially becoming the first habited place on Earth to completely rely upon solar for its energy needs. Tokelau is a tiny group of coral islands that have up to now used diesel fuel for the daily needs of its roughly 1,400 residents. Within the next few weeks, the nation will make the historic switch to solar.
Back in 1990, inventor Lonnie Johnson (pictured) revolutionized America's suburbs when the first Super Soaker was sold. Now, Johnson could be ready to deliver another gift to the masses: an energy converter that could double the efficiency of solar power, and make it a truly viable source of renewable energy.
A company called Ocean Power Technologies has come up with a tidal power generation in a familiar shape: a buoy. Now, after months in the water, the PowerBuoys have been hooked up to the energy grid, making them America's first tidal energy generators.
Idaho Governor C. L. "Butch" Otter kicked off a groundbreaking ceremony on Tuesday, signing a turbine blade that would be part of the state's proposed 183-megawatt wind farm. That's a heck of a lot of renewable energy — enough to power 40,000 homes, in fact.
You want to be eco-friendly, sure, but that doesn't mean you want to ugly up the roof of your house with a bunch of solar panels. That's why this solar glass is pretty great.
