尽管风电和太阳能装机容量持续增长，中国新能源电力浪费现象却在恶化。1根据报告，2016年近50亿千瓦时风电被弃用，占风电总发电量的17%，较上年上升2个百分点。1西北地区约20%的太阳能电力也遭浪费。1
新能源发电能力的扩张与利用率的下滑形成鲜明对比。1煤炭约占能源消费结构的72%，而风电和太阳能仅占能源生产总体的4.9%。1中国工程院院士刘吉臻指出，新能源电力浪费是风资源分布不均和电网系统不完善的结果，并建议应该建造更多输电线路以更好地利用发电。1为扭转局面，有建议称新能源项目不应在弃风率超10%或弃光率超5%的地区获批。1
China's wind and solar capacity continued to expand in 2016, yet the problem of curtailed power generation intensified, according to a report. Nearly 5 billion kilowatt-hours of wind power went unused, representing 17% of total wind electricity generation—a 2 percentage point increase from the previous year 1. In northwestern regions, approximately 20% of solar power was wasted 1.
The root causes of this inefficiency stem from uneven distribution of wind resources and inadequate grid infrastructure, including insufficient transmission and distribution facilities 1. Despite these challenges, coal remains the dominant energy source, accounting for approximately 72% of energy consumption 1, while wind and solar together comprise only 4.9% of total energy production 1. According to Liu Jizhen, an academician at the Chinese Academy of Engineering, "the waste of new energy power results from uneven wind resource distribution and imperfect power grid systems; more transmission lines should be constructed to better utilize generation capacity" 1.
To address the issue, the report recommends that new energy projects should not be approved in regions where wind power curtailment exceeds 10% or solar curtailment surpasses 5% 1.
