New device, announced at Mobile World Congress in Barcelona, will include a 50% reduction in standby energy consumption + description of solar powered phone by Samsung

So reduction in standby power is likely to lower the peak.

"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.

The bad news: organisations in the UK are wasting as much as £300 million a year by keeping idle computers switched on at night, according to a report conducted by Harris Interactive® on behalf of 1E and the Alliance to Save Energy. The good news: British organisations are much better at conserving computer energy than are their counterparts in the US. Concerns about the environment inspire 27 percent of UK workers to power down their computers at the end of the workday, according to the report. In the US, only 10 percent cited such concerns. If all the 17 million computer-using workers in the UK would power down at night, they could reduce the nation's yearly carbon dioxide emissions by about 1.3 million tonnes - about as much as is produced by 245,000 cars.

Increasing the amount of wind energy contributed to the electricity grid will not require large numbers of conventional coal- and gas-fired power plants to be kept on standby, according to a technical report published today. The report, commissioned by environmental groups including Greenpeace and Friends of the Earth, found that the UK's grid could cope with the variable energy input generated from wind farms.
