August 27, 2011 - After a three year hiatus, the CARMA global power plant emissions database is now undergoing a major upgrade. We are presently compiling a range of new datasets and revamping techniques for estimating the emissions and electricity production of the world's power plants.

For the time being, there will be no change to the data on the site, which remains unchanged from the CARMA 2.0 release in August, 2008. Our hope is to make the upgraded database public within six months.

Check back with the CARMA blog for updates as the new database comes together.

The airwaves have recently been filled with advertisements heralding a plethora of clean energy technologies. GE promoted its smart grid technologies in a Wizard of Oz-themed Super Bowl ad. Vestas, the largest wind turbine manufacturer in the world, has branded itself No. 1 in Modern Energy. Various groups have designed commercials touting the potential of "clean coal," including a GE ad featuring models-turned-miners (tagline: "Harnessing the power of coal is looking more beautiful every day."). And environmental groups have struck back against the branding of coal as "clean" with satirical advertisements (tagline: "Clean coal harnesses the awesome power of the word ‘clean!’". In this maelstrom of marketing, who can say which clean energy technology is best?

Nearly two years after the U.S. Supreme Court ordered the Environmental Protection Agency (EPA) to determine whether greenhouse gases (GHGs) pose a threat to peoples’ health or welfare – the first step toward regulation -- the EPA this week issued a draft rule on a national GHG registry:

On March 2, thousands of people are expected to engage in mass civil disobedience at the coal-fired Capitol Power Plant in Washington, DC. The protest, which is expected to include NASA climate scientist Jim Hanson, author Wendell Barry, and environmentalist Bill McKibben is timed to coincide with the final day of PowerShift09, a four-day "National Youth Summit" that aims to bring 10,000 students to Washington to lobby for action on climate change.

December 17, 2008 - Browsing power plant emissions just got easier, thanks to a new version of CARMA that you can explore using Google Earth. According to Google's site, "Google Earth lets you fly anywhere on Earth to view satellite imagery, maps, terrain, 3D buildings and even explore galaxies in the Sky." This bird's-eye view is great for comparing emissions from different countries and gives you a unique perspective of how the power sector looks worldwide. Plus, it's much cooler than tables of data!
