The image most people have in their minds when they think of wind turbines are the big, white horizontal-axis wind turbines with their massive blades spinning slowly on a wind-swept plain. But the clean energy revolution–if, in fact, it is a revolution–has room for more than just one design of wind turbine.
A reader points out that in talking about utility scale solar, only mature technologies are used — usually 20 to 30 years mature or more. He observes how long it’s taken PV to be seriously considered for plants over 10mW. But he goes on to talk about the Stirling Dish System, noticing that the system holds the efficiency world record for sun to grid electricity at 31.5%, and has (more…)
In a move that combines California environmentalism with aid to communities in need, the state has taken $3.2 billion from the California Solar Initiative (CSI) to fund solar panels on low-income housing.
Aurora Algae, formerly Aurora Biofuels, earlier this week introduced what the company says is the industry’s first photosynthetic algae-based platform for the production of sustainable products in the fuel as well as pharmaceutical, nutritional supplement and aquaculture markets. The announcement marks Aurora Algae’s transition from pilot technology development (more…)
Last week was an eventful one in venture capital clean tech funding, especially for California-based Solaria, Solazyme and Calisolar. Here’s a closer look at each of them, and what to look out for in the near future.

As of the summer of 2010, the landscape for the wind industry has changed dramatically from last year, when the U.S. set a record by installing over 10 GW in a single year and claiming the title of the world’s top wind power producer for the second year in a row.
According to recent statistics provided by (more…)
Again East Coast states have won disproportionate recognition in a national analysis of energy efficiency programs, this time from the well-respected American Council for an Energy-Efficient Economy.
ACEEE named five of the best state-led efficiency programs in a report issued Wednesday. Three of the five awards went (more…)
Everyone’s heard of solar, wind, and hydro power, but that hasn’t stopped alternative energy researchers from thinking (way) outside the box for more ways to produce heat and electricity.
Even though the world is still trying to wrap its head around the fact we don’t need oil, coal, or gas to stay warm, light up cities, and power our vehicles, many are looking (more…)
