根据联邦能源监管委员会（FERC）发布的数据，可再生能源（太阳能，风能，水电）在2020年的前九个月在2020年的前九个月中占据了新的美国电气发电能力。合并后，他们占今年前四分之三的新公用事业规模的16,886兆瓦的近三分之二或约64.1％。

FERC的最新每月“Energy Infrastructure Update”报告（到2020年9月30日至9月30日）还显示，天然气的总计为35.8％，即总计6,039兆瓦，煤炭的20兆瓦和“其他”来源的5兆瓦。自今年年初以来，核电，石油或地热能就没有增加新的能力。

在整个夏季，全部2,976兆瓦的新发电能力均由太阳能（1,484 MW），Wind（1,468 MW）和水电（24 MW）提供。仅在9月，所有新的美国电气发电能力都归因于两个新的“风”（159兆瓦）和五个太阳能单元（36兆瓦）。

现在，可再生能源占该国可用总安装能力的23.3％，并继续扩大其对煤炭的领先地位（20.0％）。现在，风和太阳能的发电能力已超过美国总数的13.3％以上，其中不包括分布式或屋顶太阳能。

For perspective, five years ago, FERC reported that installed renewable energy generating capacity was 17.4% of the nation’s total with wind at 5.9% (now 9.2%) and solar at 1.1% (now 4.1%). By comparison, in August 2015, coal’s share was 26.6% (now 20%), nuclear was 9.2% (now 8.7%) and oil was 3.9% (now 3.3%). Only natural gas has shown any growth among non-renewable sources, expanding from a 42.8% share five years ago to 44.5% today.

In addition, FERC data suggests that renewables’ share of generating capacity is on track to increase significantly over the next three years by September 2023. “High probability” generation capacity additions for wind, minus anticipated retirements, reflect a projected net increase of 27,324 MW while solar is expected to grow by 32,801 MW. By comparison, net growth for natural gas will be only 20,872 MW. Thus, wind and solar combined are forecast to provide nearly three times as much new generating capacity as natural gas over the next three years.

煤炭和石油的产生能力预计将分别下降22,346兆瓦和5,023兆瓦。FERC在未来三年内没有新的煤炭能力，只有6兆瓦的新石油产能。同样，核能预计将下降4,990兆瓦，占其目前运营能力的近5％。

In total, the mix of all renewables will add more than 61,400 MW of net new generating capacity to the nation’s total by September 2023, while the net new capacity from natural gas, coal, oil and nuclear power is projected to drop by almost 11,500 MW.

If these numbers hold, over the next three years, renewable energy generating capacity should account for more than a quarter of the nation’s total available installed generating capacity, increasing from 23.3% currently to 27.2% three years hence. Meanwhile, coal’s share will drop to 17.5% 20%, nuclear to 7.9% from 8.7%, and oil to 2.8% from 3.3%. Natural gas’s share will dip to 44.4%, compared to 44.5% now.

在过去的20个月中，FERC在每月的“基础设施”报告中定期增加其可再生能源预测。FERC在2019年3月的报告中提供了第一个这样的预测 - 预测在未来三年内增加了24,560兆瓦的风和12,048兆瓦的太阳能。在其最新报告中，这些预测在未来三年内已增长到27,324兆瓦的新风能和32,801兆瓦的新太阳能。

“不再有任何疑问that renewable energy sources are already replacing coal, oil and nuclear power while nipping at the heels of natural gas,” said Ken Bossong, executive director of the SUN DAY Campaign. “In light of campaign promises made by President-elect Biden, this trend should not only continue but greatly accelerate in the years to come.”
