Fossil fuels receive 250 different kinds of subsidies
Even though renewables get federal subsidies for research and development, they’re still at a disadvantage when competing with fossil fuels, because fossil fuels receive even more subsidies. We basically all knew that already, but few of us realized it was quite this bad. Turns out fossil fuels get 250 different kinds of subsidies, and they’re getting more all the time.

Decor that helps you feel good about your power source
These adhesive decals stick to any flat surface and are even PVC-free! Why opt for green energy if you can't remind yourself and your guests about it every time you turn on the light? I'm serious. h/t CleanTechnica

Map shows when rooftop solar will be cheaper than grid electricity
What happens if and when current subsidies for solar panels are phased out? Doesn't matter — the cost of solar photovoltaics continues to fall even as the cost of grid electricity continues to rise, which means eventually the two trends will meet and it will make more sense to put panels on your roof than […]

Bigger subsidies make bigger solar a bad bet
This post originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. Americans seem unable to resist big things, and solar power plants are no exception. There may be no reasoning with an affinity for all things “super sized,” but the economics of large scale solar projects (and […]

Harnessing the sun’s energy for water and space heating
Rooftop solar systems provide a simple, low-cost way to heat water and space.Photo: London PermacultureCross-posted from Earth Policy Institute. The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic panels that convert solar radiation into electricity, these “solar thermal collectors” use the sun’s energy […]

America must not back down on sustainable energy
Clockwise from top left: Sens. John Kerry, Sheldon Whitehouse, Barbara Boxer, and Bernie Sanders.If you read just the headlines these days, you might think renewable energy in America is going the way of Solyndra. Don’t take our word for it: A recent headline from Fox News declared “ENTIRE Solar Industry on Brink of Collapse.” We […]

Fundamental breakthrough could double electricity from solar panels
It is a truth often repeated that fundamental physical limits mean solar panels can never capture and transform more than about 31 percent of the sun's energy. But Xiaoyang Zhu at the University of Texas apparently just did the impossible, and in a most spectacular fashion: He found a way to increase the efficiency of […]

21st Century Activism: Why big business doesn’t always have to be the bad guy
Today is a great day for the future of the IT sector. Over the past few years, we’ve campaigned hard against Facebook to get them to commit to clean energy – specifically, we wanted them to change their siting policy-the decisions that they make about how to power their massive football-stadium-sized data centers. When […]

Facebook and coal are no longer in a relationship
Until recently, Facebook had an "it's complicated" relationship with coal; an April 2011 Greenpeace report found that 53.2 percent of the company's electricity use was coal-generated. Now, the company is pledging to move away from dirty fuel and work towards powering its operations, including energy-suck data centers, using renewable energy. And they're helping to spread […]
