How Many More Coal Ash Spills?

dan-river-coal-ash-ponds

What is the largest type of trash produced in the U.S.? It’s not whatever you’re thinking, most likely. It’s coal ash. Burning coal produces more than 100 million metric tons of coal ash per year—the gray or black sooty aftermath of our fossil fuel habit. Even though a good chunk of it is turned into [...]

BEIJING—A Chinese high speed train whispers into the station, before finally engaging the brakes and coming to a stop with a sound like the tinkling of breaking glass. Five years ago, such trains hardly existed. In the span of one Communist-style planning period, China has built a high-speed train network that now crosses the entire [...]

Want to know what climate change really means to people? Emily Hinshelwood found out in a most unusual way. For days on end the Welsh poet and writer walked the 121-mile train route known as the Heart of Wales Line and asked every single person she met the same three questions: What images come to [...]

“All of the Above” Energy Means More Fracking, Renewables, Nukes and Clean Coal

ernest-moniz

There is no technical issue with fracking, the controversial technique of fracturing shale rock with high-pressure, chemically treated water to release natural gas. But there is clearly a political one, judging by the multiple interruptions to a talk at Columbia University by new Secretary of Energy Ernest J. Moniz. The affable former M.I.T. professor and [...]

Does Increased Energy Efficiency Just Spark Us to Use More?

chevy-volt-fuel-economy-sticker

Last year, the U.S. raised its fuel economy standards for cars and trucks for the first time in decades. By 2025, the fuel efficiency of vehicles will be required to double. As a result, oil consumption is predicted to fall and—given that the U.S. remains the world’s largest consumer of oil—global crude prices might fall [...]

What Will It Take to Solve Climate Change?

australia-weather-map-with-new-high-temp-color

Australia had to add a new color to its weather maps this week. Meteorologists used royal purple to denote an off-the-charts high temperature of 50 degrees Celsius (122 degrees Fahrenheit), part of an unprecedented heat wave and ongoing wildfires occurring down under this month. On the other side of the globe, 2012 proved the hottest [...]

Last summer at the Rocky Mountain Test Facility in Wyoming, Lawrence Livermore National Laboratory (LLNL) scientists tested the practical potential of large-scale coal gasification facilities in a series of field experiments. This technology is considered a promising component of future “clean coal” power plants with their ability to capture and sequester carbon dioxide emissions. Photo [...]

Don’t just blame the EPA – coal exports are down, too

coalbarge_seine_385

It’s important to understand that not all of the bad news for the coal industry is coming by way of the EPA. While the CO2 limits for new coal and gas plants complicates domestic power generation, the global market for U.S. coal is softening. Up until several months ago, many people (myself included) were expecting [...]
