Wind, photovoltaic power generation cost is lower than coal financial risk in up to 74% of U. S. coal plants

Kroll spoke highly of the people in the pursuit of electric cars. But, he says, it is important to to renewable energy power. Kroll said that in the short term, car & other; Electric & throughout; Is essential for improving air quality and human health, in the long run, it also is quite important for the fight against climate change impacts.

solar photovoltaic net news: according to the VCE ( 充满活力的清洁能源) The data of the company, in 2018 the United States most of the coal-fired power plants running cost between $33 $111 / mw ( Regardless of the cost of investment) ； The leveling of 2018 solar pv costs ( Considering investment, operational full life cycle cost) At $28 - Between $52 / MWH, and the cost of wind level must change interval ( On the basis of different site resources quality) , between $88 to $13 / mw.

(35 miles of the coal power plant 56 km) Cost of wind power leveling of the photovoltaic (pv) compared with coal-fired power plants running cost, to measure the financial risk of the coal-fired power plants. In particular, has the following four kinds of situations:

1) If the wind power leveling of photovoltaic power generation cost is more than 25% higher than the cost of coal-fired power plants running, so no financial risk can be concluded that coal power plants ( 被视为无风险) ；

　　2） If the wind power leveling of photovoltaic power generation cost than the cost of coal-fired power plants running higher than 0 25%, then can be concluded that coal power plant have a potential financial risks ( 潜在的风险) ；

　　3） If the wind power leveling of photovoltaic power generation cost than the cost of coal-fired power plants run less than 0 25%, then can be concluded that coal power plants with financial risk, 在风险) ；

　　4） If wind power leveling of photovoltaic power generation cost than the cost of coal-fired power plants running low 25% or less, so can maintain coal-fired power plants have substantial financial risk of ( 大幅的风险) 。

in the United States, there are 210, 2018. 842 gigawatts of coal plants in a risky situation, accounted for 74% of the existing coal plants; And there are 93. 812 gigawatts of coal plants in substantial risk; There are 246 to 2025, American coal plants. 306 gw ( Almost all U. S. coal installed) Will be in the presence of risk; And there are 140. 073 gw at substantial risk.

although the analysis will be near coal factory and a purely economic comparison on the wind and solar power, but the results do not necessarily indicate cheap renewable energy can replace coal, also need to consider the impact on the power grid, power supply reliability and shut down the cost of coal-fired power plants and other factors.
