There are large quantities of coal mine water in Pennsylvania—much more than could be used in the coming decade for hydraulic fracturing. Researchers and operators will need to further explore quantity and quality needs to confirm whether coal mine drainage sources represent a viable, large-scale alternative to fresh water.
CUBE 2.0, an update of the 2010 release of the 1.0 version, allows users to estimate the "farm-to-gate" greenhouse gas emissions of biomass feedstocks for energy production, as well as the uncertainty in these emissions.
Coal-fired electricity generating units (EGUs) provide about 46 percent of the electricity generated in the U.S., yet most of the existing coal-fired electricity fleet is 25–45 years old. Can the industry maintain the capability to design, construct, and operate coal-fired EGUs within reasonable cost, schedule, performance, environmental, and quality expectations?
Biomass is an increasingly important source of electricity, heat, and liquid fuel. One near-term option for using it to generate electricity is to cofire biomass in coal-fired electricity plants. Factors to consider are plant-site modifications, changes in operations, costs, and logistical issues with delivering biomass to the plant.
Achieving the potential economic and national security benefits offered by alternative fuels requires that their domestic production must be an appreciable fraction of domestic demand for liquid fuels. Alternative fuels derived from oil shale and coal have the potential to meet that important criterion.
Stories discuss gays in the military, police recruitment, home health care, breast cancer, health insurance exchanges, alternative fuels, refinery taxes, alcohol prices, outer space debris, mental illness, diplomatic trends, and health care costs.
To combat climate change, the British government has thus far valued the cost of carbon emissions based on how much people should pay, rather than how much they are willing to pay, or the value they place on carbon emissions reduction. An analysis of a series of RAND Europe studies suggests there is an opportunity for a large consumer surplus — a social benefit — by introducing a carbon tax to pay for the damages caused by carbon emissions.
If the U.S. military increases its use of alternative fuels, there will be no direct benefit to the nation's armed forces. It makes more sense for the military to direct its efforts toward using energy more efficiently.
A proposed 15-cents-a-gallon gas tax is worth a second look. Among various painful options put forward in the Deficit Reduction Commission's draft report, this tax hike may be well justified, writes Martin Wachs.
Features discuss energy strategies for Israel, the economic recession, and Iran's leadership; other items discuss the KC-10 fleet, air pollution and hospital costs, no-fault insurance, silica litigation, poverty reduction, and political polarization.
Israel must control future electricity demand. It can build a secure energy infrastructure in which natural gas provides up to 40 percent of electric power generation but only by taking measures to limit supply disruptions.
