The U.S. is adding more than 2,250 MW of new renewable energy capacity each month, both utility scale and small-scale, as states reduce barriers and industry adds new technologies, according to a just released analysis of government data—with solar power particularly showing growth and growing pains.

根据联邦能源监管委员会和美国能源信息机构数据的审查，在2021年的前10个月增加了超过18,255兆瓦的新公用事业量表可再生能力，而小型项目则增加了去年的5,100兆瓦。新利18备用网址1月4日发布。

非营利性研究小组执行董事Ken Bossong说：“在未来三年中，可再生能源应从今天的大约四分之一的发电能力扩展到至少30％甚至更多。”

Solar energy added 9,604 MW in the first 10 months of 2021 and wind added 8,580 MW, with growth significantly higher than the first 10 months of 2020, FERC said in a Dec. 20 update. Hydropower, geothermal and biomass added an additional 71 MW during the same time period.

FERC说，新的天然气燃气产能增加了3,549兆瓦，而煤炭则增加了11兆瓦，燃油量增加了19兆瓦。

在2021年的前10个月中，太阳能发电率上升了约28％，在2020年同一时期大约有11％。

fercalso estimated the amount of wind and solar generation in the pipeline through 2024—deeming as “high probability" the addition of 52,692 MW of solar and 23,180 MW of wind.

能源信息局预计，仅在2022年就将增加约20,000兆瓦的新太阳能。

但是，在部署太阳能以实现雄心勃勃的碳减少目标方面，各州仍然有颠簸。

Massachusetts in 2020 had high hopes of adding 3,200 MW of solar capacity to meet its climate goals by financially supporting small projects, but progress was mired in bureaucracy, say critics.

The state Dept. of Public Utilities on Dec. 30 cleared the way for faster project approval of solar capacity needed for Massachusetts to meet its goal to halve greenhouse gas emissions by 2030, the agency said. It needs to add 7,000 MW of clean energy to meet the goal.

国家能源与环境事务执行办公室的发言人说，该机构命令设定了“一条跑道，以支持太阳能的两倍”。

Advocates say delayed rooftop and small-scale solar projects can start claiming incentive awards by mid-January.

About 3.4 GW of solar, ranging from massive grid-scale projects to smaller distributed arrays, was generating power in Massachusetts as of third quarter 2021. Under the state's "most likely" capacity forecast for 2030, about 7 GW of new clean electricity will need to be built there, of which the expanded solar incentive program will deliver 3.2 GW.

加利福尼亚has had major success in adding solar generation under its net metering program that requires utilities to pay customers for excess power they generated and sent back into the grid.

但是，随着公用事业的越来越多的推动力，说非极性客户不公平地补贴太阳能客户的电网成本，州公用事业委员会提出了终止其声称“不成比例损害”低收入纳税人的计划。新利18备用官网登录

Instead, it would offer payments to customers who add storage to their solar systems for excess capacity they generate in daytime for use at night. The new program would reduce demand for fossil fuel-generated power needed for homes and businesses during the peak evening time.

这项修订是由前专员玛莎·古兹曼（Martha Guzman Aceves）提出的，他于12月由乔·拜登（Joe Biden）总统提名，领导旧金山的美国环境保护局地区。

The proposal also creates a $600 million fund to support clean energy and energy storage programs for low-income residents.

即便如此，太阳能产业协会等太阳能公司和行业倡导团体表示，该提案下的成本较高将损害该州的太阳能增长，从而延长客户通过较低的电费赚取初始投资所需的时间。新利18备用官网登录塞亚（Seia）称这种新方法将造成“该国最高的太阳税，并破坏该州的清洁能源遗产”。

An agency vote is expected at the end of January.

同时，技术发展旨在降低部署成本。新利18备用官网登录官员们说，国家可再生能源实验室和桑迪亚国家实验室正在开发一项技术，该技术可以促进美国太阳能电池板制造业对中国进口的竞争立场。

Early next year “perovskite cells” will be deployed at Sandia’s solar testing site, to demonstrate in a field setting their touted improved ability to convert solar energy to power over typical photovoltaic silicon cells. Until now, the new cells have been subject to laboratory tests only.

此外，据该公司称，由巨型沥青屋顶木瓦公司GAF制造的一个新的太阳能屋顶瓷砖称为Timberline Solar，将太阳能技术纳入了标准的屋面材料和程序中。

“Timberline Solar installs like a regular roof, with only a nail gun required,” GAF says, adding that installation requires traditional roofing crews and supplies. The product is available in certain U.S. locations for the home construction market.
