2013년 2월 1일, 스티븐 추 장관이 미국 에너지부 직원들에게 보낸 편지 중 에너지 효율에 대해서:
Our ability to find and extract fossil fuels continues to improve, and economically recoverable reservoirs around the world are likely to keep pace with the rising demand for decades. As the saying goes, the Stone Age did not end because we ran out of stones; we transitioned to better solutions.
The same opportunity lies before us with energy efficiency and clean energy. The cost of renewable energy is rapidly becoming competitive with other sources of energy, and the Department has played a significant role in accelerating the transition to affordable, accessible and sustainable energy.
Ultimately we have a moral responsibility to the most innocent victims of adverse climate change. Those who will suffer the most are the people who are the most innocent: the world’s poorest citizens and those yet to be born. There is an ancient Native American saying: “We do not inherit the land from our ancestors, we borrow it from our children.” A few short decades later, we don’t want our children to ask, “What were our parents thinking? Didn’t they care about us?”
The Department played the crucial role in launching the Clean Energy Ministerial, in which more than 20 countries with more than 80% of the world’s GDP come together not to argue, but to share best practices. We are working to improve energy efficiency, speed the spread of renewable power and mobilize talent from around the world to advance the clean energy revolution.
