Combined heat and power, or CHP, continues to be one of those great ideas that can’t seem to get traction. In fact, the technology has lost ground, according to a recent energy efficiency report. The American Council for an Energy-Efficient Economy found that CHP installations fell 1.5 percent at industrial facilities from 2010 to 2011 in the July 2, 2013 …

For over 100 years we have relied on oil as a cheap, energy dense and portable form of power. Many advances such as plastics, ink, medicine, fertilizer, crayons, bubble gum, soup, glass and tires are heavily dependent on cheap oil. There is only a finite supply of oil in the world, and demand is increasing as the third world industrializes. …

Eric Parish asked: As our population grows and the earth’s resources are strained like never before, many people have questions about geothermal systems but are not sure about some very fundamental concerns.  Hopefully, this brief article can open your eyes to the potential of geothermal system.

Even as Congress failed to take major action on climate and energy legislation in 2010, states across the United States achieved major new strides in energy efficiency, according to the 2010 State Energy Efficiency Scorecard from the nonprofit and independent American Council for an Energy-Efficient Economy (ACEEE).

Cap and trade Cap and trade is a regulatory system that sets a government limit on overall emissions of pollutants like the warmth-trapping gases scientists have linked to international warming — the “cap.” Every company gets a bound amount of credits or permits, beyond which companies cannot emit a lot of pollution. It then permits utilities, makers and different emitters …
