Ever get a case of the yawns while sitting at your desk? Silly question – of course you do! Usually, we figure we need another cup of coffee. That jolt of caffeine might help… but opening a nearby window or stepping outside for a breath of fresh air might also wake you up: poor indoor […]

Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back slightly as the economy recovered. But shifting market conditions, pollution regulations, and changing behaviors are also behind the decline.
A recent scholarly paper decided to tackle the problem of the emissions of wind power, wishing to quantify the actual emissions so as to make accurate comparisons between wind power and other sources of electrical power generations.

Earth Policy Institute: The End of an Era — Closing the Door on Building New Coal-fired Power Plants in America
By Jonathan G. Dorn Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been canceled or postponed in the United States—59 in 2007, 24 in 2008, and at least 12 in the first […]
The G20 Global Summit, which will take place in the UK in April, stands to be an important factor in determining China’s stance on climate change commitments as Copenhagen draws near. First, this meeting will provide the US and China a chance to meet behind the scenes, for the first time since Hillary Clinton visited […]
By Lester R. Brown As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere […]
Editor’s note: Many thanks to Dr. John at Flopping Aces for bringing this 6-year-old-post back into our “Popular Right Now” column for a few minutes. I hope he’s given himself a good pat on the back for his snarky observation; I hope you’ll read just a bit more than he obviously did…. it’s a short post, […]
Quicker-melting snow cover will allow forests to encroach on meadows and, ironically, eventually aid in cooling the planet. Regina Rochefort, a National Park Service science adviser at Mount Rainier, said the meadows surrounding the famous peak have been shrinking because of less snowfall and shorter periods of snow cover. In the past, the snow has […]
A North American organization of energy experts issued a report that found that building more green buildings is the best way to cut carbon dioxide emissions (CO2), one of the major contributors to global warming. In fact, green buildings could cut emissions more deeply, quickly and more cheaply than any other global warming mitigation effort. […]
Spurred by looming federal policy on CO2 emissions, many banks are exploring how to mitigate their financial risk as much as possible. This week, Citigroup, Morgan Stanley, and JP Morgan announced guidelines to help them determine whether to lend money to projects that emit a lot of carbon dioxide (CO2) – like coal-fired power plants. […]
Florida Governor Charlie Crist (R) signed an executive order last summer to develop a carbon market in the state, and has been making other good strides in the renewable energy department. Now, the governor, lawmakers, and Florida-based companies are debating the two main methods of carbon control: A carbon tax or a cap-and-trade system. A […]
The end of 2007 brought with it news of cleantech developments for 2008 and beyond. Here are a few that I found most interesting. Do any sound promising to you? Fuel Cubes A Minnesota company called Renewafuel has developed a biomass briquette that is similar in size and moisture content to coal, produces a consistent […]
