I wanted to share how a company shutdown can save a company energy. At Yahoo!, during the holiday week last year, there was a holiday shutdown where employees were encouraged to either take the week off or work from home. The offices operated minimally for those who did go into the office. Yahoo! also gave away 2,000 CFLs in the lobbies of the Sunnyvale and Mission College campuses. The shutdown resulted in a 107,000 kilowatt hours decrease of energy consumption which equates to a savings of 73,000 pounds of CO2 and also equates to $12,000 in estimated savings.
