America’s Department of Energy is investing $3.9bn in ‘smart grid’ technology, aimed at making power transmission around the country more flexible.
Steven Chu, the US Energy Secretary said the funds would help create a system to allocate electricity more efficiently. This will done through improved power lines by allowing batteries in hybrid cars to feed back into the grid when needed.
“Right now, the way we distribute energy, it’s like plumbing – it’s down the hill:’ he told reporters recently. When asked about people objecting to high-voltage power lines being built near their homes as part of a smart grid, Chu said he would appeal to US national interests.
