Bringing Décor to Life with Photosynthetic Furniture
Say goodbye to the houseplants you keep forgetting to water, and embrace a new trend: decorative, functional microorganisms. Innovations in industrial and architectural design might soon bring photosynthesis into your home in a completely new […]
Could our Future World be Made of CO2 from Air?
Researchers at George Washington University in Washington, DC have devised a way to pull CO2 out of air and turn the carbon into carbon nanofibers, the wonder material that now makes racing bikes and other high […]
Hillary Clinton’s Presidential Campaign Pushes Ambitious Green Energy Goals
Hillary Clinton has made renewable energy a big part of her election platform, and has some very ambitious plans to reshape the energy landscape of the United States. As the 2016 election season approaches and the […]
Solar Desalination to Ramp up in California
For making steam, solar thermal is already cheaper than fossil fuels. Desalination puts this cheap steam tech to great use. An innovative solar project in California will clean agricultural water through solar distillation, using the sun’s […]
Australia’s Prime Minister Cuts Funding for Wind Power
Australia’s Prime Minister, Tony Abbott, doesn’t like wind turbines. He has made dramatic cuts in government subsidies for wind farms, in a move that’s sure to hold back Australia’s renewable energy sector. Tony Abbott has […]
White House Initiative Brings More Solar Power to Low-Income Communities

From Coal to the Cloud: Google “Upcycles” Defunct Power Plant Into its Newest Data Center
Anyone with scissors, thread, and access to a craft website can upcycle old t-shirts into tote bags, but it takes a multinational corporation like Google to upcycle a decommissioned coal power plant into a data […]
Free Solar Power in California: Thanks, Cap-and-Trade!
California’s cap-and-trade program brings in money when carbon allowances are auctioned. A lot of money – about $1.49 billion in the current fiscal year alone, the state said last week. The law requires that “the state […]
Akon’s ‘Solar Academy’ Aims to Light Up Africa
There are some who argue that Africa needs fossil-fuel-generated power in order to boost standards of living and end the deprivation that afflicts too many. Just can’t do without it. But Akon is taking a different approach […]
Community Solar Spreading the PV Goodness
The story of rooftop solar power in recent years is one of challenges conquered. Panels too pricey? Scaled up production (in China, mainly) took care of that. System capital costs still too high? New finance models, […]
China Solar Power Surges: Leaves Entire World Behind
China issued an update on its solar progress this week and made every other solar-seeking country around the world feel kind of pathetic. The National Energy Board said 5.04 GW was installed in the first quarter […]
Putting a Price on Carbon: A Tough, But Necessary, Nut to Crack
Carbon dioxide exacts a cost, that much we know. It’s when we try to take the logical next step – putting a price on carbon – that things get complicated. The issue is in the […]
All Signs Point to Solar Power Juggernaut Rolling On
It’s not a contest. Renewable energy is no zero-sum game (or doesn’t have to be, at least), and according to the experts, all of it and then some will be needed to keep global temperatures […]
