A big slice of President Barack Obama’s $825 billion stimulus package for the United States includes a boost to renewable energy, “weatherizing” a million homes, and upgrading the country’s inefficient electricity grid. Such investments could generate an estimated five million “green-collar” jobs, provide a shot in the arm for the construction and engineering industries, and get America back into the equally serious business of combating climate change and achieving energy security.
奥巴马总统价值八千二百五十亿美元的经济刺激计划中有一大部分包括大力提高可再生能源，给一百万房屋改进取暖御寒性能并且改进美国低效率的电网系统。这些投资可以产生大约五百万“绿领”工作，给建筑和工程产业注入一剂强心针并且把美国带回到气候变化以及实现能源安全的同样重要的任务上来。
