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...

You've purchased a new energy-efficient washing machine and refrigerator. So, will your utility bill reflect a huge savings?The easy answer is: It depends. It depends on the size and age of the appliance you're replacing, as well as your definiti...

"CarbonCulture is a new initiative started by More Associates for organisations that want to get really good at saving energy and carbon. Structured as a social enterprise, CarbonCulture exists to help all its members find the best 'moves' they can make to save energy and carbon. CarbonCulture will spread that knowledge amongst the membership so we can all get better at saving as quickly and as cheaply as possible. We've been working for some time with pioneers DECC and Defra to design strategies to achieve initial savings." http://www.carbonculture.net/orgs/decc http://www.carbonculture.net/orgs/dcms http://www.carbonculture.net/orgs/cabinet-office http://www.carbonculture.net/orgs/defra http://www.carbonculture.net/orgs/fco http://www.carbonculture.net/orgs/hmrc http://www.carbonculture.net/orgs/hm-treasury

Energy-saving tips from a random source. Recently, there have been a few posts on the subject.

By Jorge Moreno, Environmental and Building Technologies, Frost & Sullivan With more end users focusing on reducing energy costs, energy-saving water-to-water heat pump (WTWHP) chillers are being deployed to reduce a facility's utility bills. A WTWHP chiller is a water-cooled chiller that is designed to produce hot water at a specified temperature. The use of a WTWHP chiller is very similar to a conventional centrifugal chiller except for the fact that it uses two compressors, slightly different piping configurations, and more advanced controls in order to balance cooling and heating loads. In a conventional chiller, cold water is produced for comfort cooling, and the hot water that is extracted from the refrigeration process goes into a cooling tower and is released into the atmosphere. In a WTWHP chiller, this hot water is captured and relocated to a second heating stage, where the temperature is raised and the water is used as a heating source for a building's heating requirements. The key strength of WTWHP chillers is the high coefficient of performance (COP) that translates into significant energy savings and a shorter payback period. On the other hand, the key weakness is that it can only provide such benefits in a narrow range of applications primarily due to its coincident need for cooling and heating requirements throughout the year to ensure efficiency. A coincident need means that the application demands sizable water heating load along with the typical high cooling requirements in summer, and a sizable chilled water load along with the typical heating requirements during winter. Cooling output is directly dependent on the demand for heating, and vice versa. Consequently, in the absence of sufficient heating requirements, there is only a limited amount of cooling that can be produced. Any excess heating or cooling cannot be stored and hence, it is critical to align the cooling with the expected heating requirements. Coincidentally, in the absence of suf

The Tokyo Metropolitan Government (TMG) announced on May 14, 2012, that it has formulated a policy for promoting energy conservation and management, titled "Toward a Smart Energy City Beyond Power-Saving" (unofficial translation). In addition to i...

"Personal computers in enterprise environments save energy and money by "sleep-working," thanks to new software called SleepServer created by computer scientists from the University of California, San Diego. Sleep-working enterprise PCs are accessible via remote connections and maintain their presence on voice over IP, instant messaging, and peer-to-peer networks even though the PCs are in low-power sleep mode. SleepServer can reduce energy consumption on enterprise PCs previously running 24/7 by an average of 60 percent, according to a new peer-reviewed study presented by UC San Diego computer scientists on June 24 at the 2010 USENIX Annual Technical Conference in Boston.

Despite what marketers of products such as bamboo cutting boards and vegan silk gowns would have us believe, helping the planet doesn't require forking over your paycheck. It's really about conserving, not consuming -- so going green should also save you some.
