清洁能源正席卷美国. 2020年，美国产生了 几乎是可再生能源的四倍 从2011年的太阳和风开始 风能和太阳能现在提供了全国11%的电力. 能源效率的进展, 电动汽车, 电池存储, electric home heating and other technologies mean that it is now more possible than ever to envision a future powered by 可再生能源.
The recent growth of 可再生能源 in the United States is no accident - it’s the result of strong leadership by key states, 以及联邦政策的支持. “2021年可再生能源的崛起” tracks the growth and improvement of clean energy technologies over the last decade and makes the case for a bold commitment to a clean energy future.
The data story below shows how the nation has set - and exceeded - increasingly ambitious goals for 可再生能源.
The last decade has seen rapid growth in the key technologies needed to power America with clean, 可再生能源.
太阳能: 美国的太阳能发电量是2011年的23倍, 足够为1200万普通美国家庭供电.
风能: America has nearly tripled the amount of 风 power it produces since 2011, 足够为3100万家庭供电.
能源效率: 全美的电力效率项目.S. saved over 17% more energy in 2019 than in 2011, as states ramped up their investments in efficiency. 2018年，这些项目节省的电力足够2个以上.500万个家庭.
电动汽车: In 2011, just over 16,000 battery and plug-in hybrid 电动汽车 had been sold in the U.S. 截至2020年12月，这一数字增长了100倍，达到近1人.700万辆汽车. By mid-2021, cumulative plug-in electric vehicle sales had surpassed 2 million.
电池存储: 到2020年，美国将成为世界上最大的石油生产国.S. 有超过1.7 GW of battery energy storage—a critical technology to unlock America’s vast clean energy potential. The nation’s 电池存储 capacity grew more than 18-fold from 2011 to 2020 and grew by 67% in 2020 alone.
热泵: The efficiency of electric heat pumps has improved to the point where they are now an attractive and realistic option for heating and cooling homes across the country. 在2015年，12%的美国人.S. 使用热泵供暖的家庭，十年前只有8%. 从美国进口的高效空气源热泵.S. manufacturers nearly doubled between 2011 and 2020, increasing by 10% in 2020 alone.
清洁能源在美国的快速增长.S. has been driven in large part by ambitious state 可再生能源 targets, as well as clean energy tax credits and other supportive policies adopted at the state and federal levels. Nine states—accounting for one-fifth of the nation’s power consumption—have committed to getting 100% of their electricity from carbon-free sources such as 风 and solar power, 还有近200个城镇.

2011年至2020年, 风, solar and geothermal power production increased at an average rate of 15% per year. 如果同样的增长率继续下去, America could meet all of its electricity needs with 可再生能源 by 2035.
Rapid improvements in technology are making it possible for America to tap even more of the nation’s vast clean energy potential:
In 2019, the average capacity of a newly installed 风 turbine was 42% greater than one installed in 2010.
The median new residential solar panel installed in 2019 was around 37% more efficient than one installed in 2010.
The median range of a new electric vehicle more than tripled between 2011 and 2020—with the median new EV now able to travel more than 250 miles on a single charge.
Even as clean energy technologies have been improving, prices have been falling dramatically.
2010年至2018年, the cost of distributed solar photovoltaic systems fell by 71% and the cost of utility-scale systems fell by 80-82%.
同期，陆上风力发电的成本下降了66%.
Extremely efficient LED light bulbs cost over $40 a piece just over a decade ago, but technology improvements mean that they now cost less than $2 per bulb.
进一步大幅降低成本是有可能的:例如，美国石油公司(u.s. oil corp .，简称:美国石油公司).S. 能源部的目标是降低电网规模的成本, 长期储能技术将在十年内达到90%或更多.
美国.S. 是否应该渴望满足所有的能源需求——电力需求, 交通和工业与清洁, 可再生能源, 并制定相应的政策和项目来实现这一目标.
美国拥有巨大的清洁能源潜力. 50个州 has the potential to generate as much power as it currently uses with either 风 or solar energy. 过渡到清洁, 可再生能源 is not only necessary to prevent the worst impacts of global warming, 但它也可以预防 有害空气污染 that threatens our health and reduce environmental threats from extracting, 加工和运输化石燃料.
打造一个100%可再生能源的未来, state and federal officials should adopt bold 可再生能源 goals and put in place the supportive policies needed to meet them. 具体地说,政策制定者应该:
Set 100% 可再生能源 targets as well as specific targets for key technologies such as solar power, 海上风力能源, 和能源存储.
为采用可再生能源建立强有力的激励措施, including extension and expansion of federal tax credits that have helped fuel the growth of clean energy.
确保公用事业法规支持可再生能源的发展, including through policies like “net metering” that compensate owners of 可再生能源 systems fairly for the energy they supply to the grid.
Encourage the transition to 电动汽车 and buildings through strong “clean cars” standards and improved building codes.
Increase investment in energy efficiency programs and set strong building energy codes and efficiency standards for appliances.
