After several false starts, 2010 finally could be the year when smart meters go global. The technology, which lets energy companies and consumers more closely monitor their electricity consumption, has many champions. The U.S. government has earmarked $4.5 billion from the stimulus package to subsidize the rollout of smart meters nationwide. European Union politicians are pushing hard to connect 80% of the region’s homes and businesses to smart meters by 2020. Even emerging giants like India and China aim to install the technology in new buildings.
