Across the U.S., researchers, startup companies and investors are exploring the potential of creating large amounts of green, renewable fuel from the humblest of sources: algae.

If you think the energy/food potential for hemp is underutilized, wait’ll you get a gander at algae. This little microorganism really packs a punch.

According to The Book of General Ignorance: Everything You Think You Know is Wrong (2006, Harmony Books) (I highly recommend it, by the way — it’s packed with fascinating information and weird insights), algae breathes out more oxygen than all the world’s land-based plants and trees combined. Certain types of algae also deliver a whopping amount of protein and nutrients per farmed acre (20 times more than soy beans, in the case of spirulina).

The inspiration in their case: an avalanche that severed the hydroelectric power lines serving the remote Alaska capital, cutting off about 80 percent of the city’s available electricity.

Texas comes out on top in the American Wind Energy Association’s (AWEA) 2007 rankings of wind energy leaders, not only in its overall total number of wind turbines but in the amount of new capacity added last year.

Texas wind turbines generated 4,446 megawatts of energy in 2007 — enough to power nearly 1.2 million homes. The state added 1,618 megawatts of new wind power capacity last year, more than double the amount of second-place Colorado.

The Florida Solar Energy Center (FSEC) and Washington State University are both developing regional centers to promote energy-efficient technology and “beyond-code” construction.

Both of the “regional building technology application centers” are being funded by a multi-million-dollar grant from the U.S. Department of Energy.
