Photo credit: ACS Nano That’s the name researchers at the University of Notre Dame have given to their solar paint that uses nanoparticles to generate electricity. “We want to do something transformative, to move beyond current silicon-based solar technology,” says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an [...] BP Plc, Europe’s second-largest oil company, will shut its solar power unit and quit the business entirely after 40 years because it’s become unprofitable. They are staying in wind and biofuels though. Solar has become cut-throat competitive as prices keep dropping. Click to open PDF Desertec is a set of plans for a massive network of solar and wind farms stretching across the MENA region and intended to connect to Europe via high voltage direct current transmission cables (which are supposed to only lose 3% of their electricity per 1000km, or 620 miles) This mammoth [...] Stored energy is the ability to take generated electricity and store in a form where it can be used later, on-demand, as needed. This is especially important for renewable energy. Wind and solar plants need to be able to store power for use when the wind has stopped blowing or when the sun isn’t [...] Kenya ad for ToughStuff solar. Their small solar panels recharge cell phone, portable radios, and lights. CleanTechnica has more. BrightSource Energy, the California solar power plant builder, largely backed by President John F. Kennedy’s nephew, Robert Kennedy Jr., was granted a 1.4 billion dollar bailout through a loan guarantee issued by a former employee-turned Department of Energy official . solarpros.com The California Public Utilities Commission has apparently never met a renewable energy project it didn’t want to approve. Further, it seemingly cares little about trifles like price and the effect of sharply steeper electricity prices on California ratepayers. Electricity is what keeps everything going, and higher power prices will certainly have an unwelcome [...] green.blogs.nytimes.com Installations of rooftop solar in California are booming, even in the middle of a nasty recession. The state just reached 1000 MW (1 GW) installed statewide, with 205 MW of that in 2011 alone. This cumulative total is more than all but a few countries. Primary among the reasons are the rapidly falling [...] Solar-Powered Landfills from Energy NOW on Vimeo. A massive membrane with solar panels covers a landfill. You can walk on the panels without harming them. Output is 1 MW, enough for 224 homes. (crossposted from AZIVN) In an effort to speed development of solar power in the West, the U.S. Department of the Interior has proposed 17 sites as meeting multiple criteria, in hopes that developers will build grid-scale solar projects on them. Finding sites for big solar can be problematic. They can require thousands of acres [...] |  | ||||
