Many solar farm designers didn’t plan for the high grasses that would grow up and block precious sunlight from solar panels. The solution? Solar sheep! Here’s an eco-business that’s new, different, and in demand.
A new French start-up, NewWind, is making wind power beautiful! Their new Wind Tree offers almost a hundred mini-windmills on an apparatus designed to look like a tree. Due to the light construction of the “leaves,” the Wind Tree generates power at wind speeds as low as 4.4 miles per hour! This translates into sustained […]
I’ve written in the past about the fact that 100% of the world could be powered from clean, renewable energy. But to get to that 100% target, you need a lot of small 100% targets (i.e. 100% renewable energy for Scotland, for Tokelau, etc.). A report just out yesterday from the Institute for Energy and Environmental Research finds that Minnesota could easily go 100% renewable. Not only that, though — it could use 100% local clean power from solar and wind energy. That’s exciting.
We are inundated daily with so much bleak information about petroleum, as well as the many environmental problems and wars associated with oil, that it is a relief to read some positive energy news. Some creative thinkers are already devising much more sustainable technologies for our future.
This week the prestigious Lemelson-MIT award was given to Miles C. Barr, a scientist and “pay it forward” advocate, for his work developing an inexpensive process that can print photovoltaic solar cells on common items, like paper, fabric and ordinary construction materials.
When officials from AORA cut the blue ribbon to launch the Tulip CSP system in desert country north of Almeria, Spain, I was able to sit with Pinchas Doron, PhD, the AORA Solar chief technology officer, to learn more of this innovative hybrid system. What follows is a condensed version of that interview.
Superfund sites, landfills and depleted mines don’t exactly bring to mind renewable energy opportunities. And yet the U.S. Environmental Protection Agency thinks there might just be, in the midst of all the industrial waste, pollution, and environmental neglect being cleaned up at these sites, a green opportunity — a renewable energy opportunity.
Not quite Scotland’s goal of 100% renewable energy by 2025, but still a highly ambitious one (relative to other countries), Denmark’s newest renewable energy target proposals aim to have wind supplying it with half of its electricity by 2020, and renewable energy supplying it with ALL of its energy by 2050. And all of its power and heat would come from renewables by 2035.
South Korea is a definite cleantech leader. Its cleantech investments per GDP are many, many times more than the US’, or any other country’s I’m aware of. Check out the graphics below on percentage of countries’ stimulus packages that went towards green technology — South Korea is the last pie.
Today instead of asking how to get rid of waste, many are asking how they might put parts of the waste stream to better use, like making their own fertilizer and gas, for instance.
Scenes from the Seattle Moving Planet “Rally to Move Beyond Fossil Fuels” held at South Lake Union Park, Saturday, September 24, 2011 and organized by 350.org.
What’s it like to live in an Ecovillage? Find out in this first post of a series on Dancing Rabbit Ecovillage.
Talk about landing the Holy Grail of solar power. Santa Monica startup SolarReserve locked in $737 million in guaranteed loans from the U.S. Department of Energy last Thursday for its highly innovative solar energy plant.
Google’s product portfolio has now expanded from search engine power to solar power.
The results of a recent survey by Sun Connect, an Australian solar power installation company, show that rising electricity bills have a major influence on homeowner’s decisions to go solar. Respondents pointed to high electricity bills, anticipated electricity price rises, and pain caused by high power costs, as significant areas of concern. In fact, when […]
