Energy officials from the US and China signed a memorandum of understanding today to improve industrial energy efficiency, Bloomberg reported. Under the agreement, the US will send officials to China to train local authorities in identifying wasted energy and installing energy-saving systems before the end of the year. Encouraging China to adopt energy-saving technologies may cut global warming pollution and provide a sales opportunity for American makers of efficient equipment such as motors and boilers, said Karen Harbert, assistant secretary for policy and international affairs at the US Department of Energy. US government reports show that China will consume more energy than the US by 2030.
