美国EPA能源明星新闻

The U.S. Environmental Protection Agency (EPA) announced today that 70 manufacturing plants have achieved Energy Star certification for their superior energy performance in 2014. Together, these manufacturing plants saved a record amount of energy, cut their energy bills by $725 million, and reduced greenhouse gas emissions by more than 8 million metric tons — equivalent to the annual total energy use of more than 650,000 households.
