據OE網站7月13日報道，根據國際可再生能源機構（IRENA）的一份報告顯示，去年新增的近三分之二或163吉瓦可再生發電裝機容量比G20國家最便宜的燃煤發電廠成本低。

據報告稱，與2020年相比，去年陸上風力發電成本下降了15%，海上風力發電成本下降了13%，太陽能光伏發電成本下降了13%。

煤炭和天然氣的價格在過去一年里飛漲，給工業、企業和消費者帶來了壓力。尤其是歐洲天然氣價格大幅上漲。

IRENA表示，歐洲高企的天然氣價格將使歐洲新一代天然氣發電在其使用壽命內變得越來越不經濟。

據報告稱，今年，現有天然氣發電廠的燃料和碳許可成本可能比2021年投入使用的新太陽能光伏和陸上風能的壽命成本平均高出4到6倍。

今年1月到5月之間，太陽能和風能發電可能為歐洲節省了約500億美元的化石燃料進口成本。

該報告稱，并非所有材料成本的增加都已轉嫁到設備價格和項目成本上。如果原材料成本居高不下，今年的價格壓力將更加明顯。

Two-thirds of New Renewable Power Cheaper than Coal in 2021 - IRENA

Almost two-thirds or 163 gigawatts (GW) of new renewable power capacity added last year had lower costs than the cheapest coal-fired power plants in G20 countries, a report by the International Renewable Energy Agency (IRENA) showed.

Last year, the cost of electricity from onshore wind fell by 15%, offshore wind fell by 13% and solar photovoltaic (PV) fell by 13% compared to 2020, the report said.

"Renewables are by far the cheapest form of power today," said Francesco La Camera, director general of IRENA. "Renewable power frees economies from volatile fossil fuel prices and imports, curbs energy costs and enhances market resilience, even more so if today’s energy crunch continues."

Prices of coal and natural gas have rocketed over the past year, putting a strain on industries, businesses and consumers. European gas prices have spiked in particular.

IRENA said high European gas prices will make new gas-fired generation in Europe increasingly uneconomic over its lifetime.

Fuel and carbon permit costs for existing gas plants might average four to six times more this year than the lifetime cost of new solar PV and onshore wind commissioned in 2021, the report said.

Between January and May this year, the generation of solar and wind power might have saved around $50 billion in fossil fuel import costs in Europe.

The report said not all material cost increases have been passed onto equipment prices and project costs yet. If material costs remain elevated, price pressures this year will be more pronounced.
