New Energy Star criteria for washing machines, CFLs
By July 1, 2009, all qualifying Energy Star washing machines will have to be at least 43% more efficient than the current federal energy efficiency standards and have a maximum water factor (WF) of 7.5; that is, each load will use 7.5 gallons of water per cubic foot of capacity.
By January 1, 2011, all Energy Star washing machines will be 59% more efficient than mandated energy standards and will have a maximum WF of 6.0. The 2011 criteria are expected to save consumers $120 million on annual utility bills while saving 11.2 billion gallons of water and 659 million kilowatt hours of electricity.
Energy Star is a joint program of DOE and the U.S. Environmental Protection Agency.
To meet the new Energy Star criteria, compact fluorescent lamps must be low in mercury while meeting more stringent color requirements.
The DOE also announced more stringent Energy Star requirements for compact fluorescent light bulbs (CFLs.) As of November 2008, CFLs must be tested by an independent third party, and as of December 2, 2008, all Energy Star CFLs will be required to contain less than 5 milligrams of mercury per bulb and to meet more stringent lamp color requirements.
CFLs with reflectors, such as spotlights, will have to meet new high-heat testing requirements. The criteria will also be expanded to include CFLs with a smaller screw-in base, called a "candelabra" base.

Electricity demand set to reduce if UK workforce self-isolates
LONDON - National Grid ESO is predicting a reduction in electricity demand in the case of the coronavirus spread prompting a lockdown across the country.
Its analysis shows the reduction in commercial and industrial use would outweigh an upsurge in domestic demand.
The prediction was included in an update from the Energy Networks Association (ENA), in which it sought to reassure the public that contingency plans are in place to ensure services are unaffected by the coronavirus spread.
The body, which represents the UK's electricity and gas network companies, said "robust measures" had been put in place to protect control rooms and contact…
