Bill Gates didn’t mince words last night when sharing with the IHS CERAWeek crowd his thoughts about public support for basic scientific research in the United States.

China will reduce the nation’s carbon emissions and energy use per unit of gross domestic product (GDP) by at least 3.7% this year and perform trials for a carbon-trading program, China’s National Development and Reform Commission (NDRC), said in a report on Tuesday. The country would also make "greater efforts to conserve energy" and "reduce the discharge of major pollutants," it’s top economic planner said.

Energy demand in Mexico, according to the Secretary of Energy (SENER), will increase by approximately 4% each year for the next ten years, and with it the potential for private sector growth in the industry. Download the report.

Mercury emissions from power plants in 137 United Nations member countries could be subject to strict controls and reductions if an international treaty is signed by participating nations this October.

Four bouts of dense smog described as the worst air pollution in recent memory enveloped more than half of China in January, from the Beijing-Tianjin-Hebei triangle in the north of the country to Nanjing in the south, via the central city of Wuhan.

Feedwater heaters are used to preheat boiler feedwater by condensing steam extracted from several stages of the steam turbine. Feedwater heaters enhance the thermal efficiency of the power plant by reducing the amount of fuel burned in the boiler to produce a specified power. At the same time, the steam energy extracted from the turbine by the feedwater heater helps to reduce the rate of energy rejection to the environment via the condenser.

The use of low-grade coal is becoming synonymous with circulating fluidized bed (CFB) power plants. Although CFB technology may often be a better choice than pulverized coal technology, that is not always the case. Owners and developers need to consider several technical and economic factors before making this decision.

Steam turbine blade cracking often suggests the need for an upgraded blade design. Follow the process of reversing engineering a failed blade to produce a more reliable and efficient design.

A modified settlement reached between American Electric Power (AEP), a coalition of citizen groups, and the Environmental Protection Agency (EPA) on Monday will allow the utility to install less expensive pollution controls on a coal-fired power plant if it ceases coal combustion by 2015 at three aging power plants in Indiana, Ohio, and Kentucky.

The Advanced Research Projects Agency-Energy (ARPA-E) may be the most important federal agency many in the power industry have never heard of. Whatever generation technology you are associated with, ARPA-E’s work will affect its future.
