Poland, like many East European nations, relies heavily on coal. Approximately 90 percent of the country’s electricity comes from coal. Worse yet, over two thirds of Poland’s coal-fired plants are over 30 years old and thus highly inefficient.
This means Polish citizens breathe the second (more…)

What the Sierra Club has done with its “Beyond Coal” campaign is pretty impressive, making a huge swath of the American public aware of the health and environmental issues associated with coal-fired power plants – not only their CO2 emissions, but also their heavy metals, SOx, NOx, etc. It’s really one of the most effective public education efforts I can (more…)

A red alert has been issued for several cities in northern China including Changchun and Harbin. A red alert is the highest level on the four-tiered alert system and is defined as serious air pollution for three consecutive days. According to Xinhuanet News, “the density of PM 2.5 — airborne particles measuring less than 2.5 microns in diameter, (more…)

Occasionally I hear that the Chinese government is very concerned about keeping its huge population content – or at least sufficiently calm that the people don’t riot in the streets. I don’t really understand this, as the government hasn’t been particularly afraid of rounding up protesters and putting bullets through their heads. (more…)

One of the U.S.’s largest electric utilities has agreed to close three coal-fired power plants in the Midwest, the latest sign of how the U.S.’s electricity supply is shifting away from coal to natural gas and renewable energy.
American Electric Power (AEP) will shut down the three plants in Indiana, Ohio and Kentucky by 2015 — retiring a total of 2,011 megawatts of coal-burning (more…)

Coal is somewhat notorious for not being the cleanest of fuels. Similarly all combustion systems release a good deal of carbon dioxide. A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale. (more…)

Here’s an article by Peter Lehner, Executive Director of the Natural Resources Defense Council (NRDC), who writes on the levels of air pollution in Beijing, which last week reached a level of 755–on a scale of 0 to 500 (the scale on which our Environmental Protection Agency here in the U.S. rates anything over 300 as “hazardous.”) The Internet is littered with (more…)

Coal could rival oil as the world’s largest energy source within five years as consumption continues to climb in most regions of the world, a trend that could have profound effects on the climate, the International Energy Agency (IEA) says.
While coal consumption is expected to decline in the (more…)

Here’s an overly simplistic article that questions the validity of electric vehicles as “green” transportation, suggesting that charging EVs can require more coal to be burned. I note the comment: “I power my electric car totally from solar PV panels. This article should be citing coal-fired power plants, not electric cars.” He has an excellent point, but, since most EV (more…)

A decline in U.S. carbon emissions in recent years is unlikely to continue over the long term unless there is a significant shift in how the nation produces and uses its energy, according to a new analysis.
While several factors have triggered a 9 percent decline in annual carbon emissions in the U.S. (more…)
