Under this program, eligible projects may be financed at 0% interest. The "loan" is paid back through the customer's PG&E bill: with the reduced energy savings at least offsetting the loan repayment cost. Once the loan is paid off, the savings are...

The Energy Department today announced a new partnership between the Department's Challenge Home program and Passive House Institute US (PHIUS) on a voluntary certification process for homes that are so energy-efficient, they can offset most or al...

American Electric Power annouced that it is expanding its use of large-scale battery technology on its electricity grid by installing six megawatts of sodium sulfur (NAS®) batteries for storage of electricity to enhance reliability, allow for continued load growth, provide support for weak sub-transmission systems, avoid equipment overload and to offset intermittent wind power. AEP will be adding stationary sodium sulfur (NAS®) battery technology in its West Virginia and Ohio service territories next year. The company will also work with wind developers to identify a third location for NAS battery deployment ...to help offset the intermittent nature of wind generation.

The 15,200 megawatts of new wind turbines installed worldwide last year will generate enough clean electricity annually to offset the carbon dioxide emissions of 23 average-sized U.S. coal-fired power plants, according to a new Vital Signs Update from the Worldwatch Institute.[1] The 43 million tons of carbon dioxide displaced in 2006 is equivalent to the emissions of 7,200 megawatts of coal-fired power plants, or nearly 8 million passenger cars.

According to researchers from the Carnegie Institution, the University of California, Merced and Stanford University, converting biomass to electricity delivers 80% more miles per acre of crops and doubles the potential for greenhouse gas offsets.

Chemical reactions that pull carbon dioxide out of the atmosphere and store it in the form of solid rock inside geological formations could offset billions of tons of carbon-dioxide emissions each year

A recent study by Logan group at Penn State University also demonstrated similar findings in that the energy contained in hydrogen gas not only can offset the energy used for the desalination process but has surplus that can be used for downstream processing.

Several years ago even the mobile phones were very expensive, not to mention computers and airplane flights.

The example of mobile phones is of little relevance here, because cost reduction is driven by the scaling laws of microelectronics. However, the reducing cost of flights - in a way the ultimate energy application - offer a good benchmark. What will happen to flights though if commodity and energy prices go up in the long run?

Yet another story of apples and oranges.
