As US Electricity Use Stalls, Utilities Scramble Household use to expand just 0.7% per year: feds By Matt Cantor, Newser User Posted Jan 3, 2013 6:12 AM CST 38 comments Comments In this Aug. 25, 2011 file photo, an attorney holds an Apple iPad, left, and a Samsung Galaxy Tab 10.1.

In the middle of the 20th century, electricity use grew about 8% yearly; now, it's set to expand just 0.6% per year for industry and 0.7% per year for homes through 2040, according to federal assessments. Electricity use was once considered a good measure of economic growth—but perhaps not so anymore, particularly as manufacturers build devices that use less energy, the Wall Street Journal notes. That leaves utility companies in a bind as they rush to reorganize their finances. Fearing a credit downgrade, Exelon is cutting spending on nuclear and renewable projects by some $1 billion each. And a number of companies are turning their focus from their unregulated operations to their more-profitable regulated efforts, like power transmission. Among the new strategies: investment in new high-voltage power lines, encouraged by regulators as a means of revamping the US power grid. "They don't see any light at the end of the tunnel and are making adjustments," says a consultant.
