風力の発電能力、初めて原発抜く コスト減、普及後押し

世界の風力発電施設の発電能力は今年、4億キロワットを超え、原発を初めて上回ることがわかった。発電コストが大幅に下がり、普及を後押ししている。今月の国連気候変動会議(COP21)で採択された「パリ協定」に基づき各国は温暖化対策として再生可能エネルギーを増やす方針を示しており、風力発電もさらに拡大しそうだ。

風が吹く時にだけ発電する風力は稼働率が30%程度で、80%近い原発に比べ実際の発電量は約3分の1程度とみられる。ただ、世界風力エネルギー協会(WWEA)は、風力の発電能力が2030年には20億キロワットに達すると見込む。いまの傾向が続けば、発電量でも風力が原発を超える可能性がある。

WWEAの6月末時点の集計で風力の発電能力は3億9293万キロワット。風力発電の専門誌「ウィンドパワーマンスリー」が27日に発表した今年末時点の見通しでは、4億1496万キロワットに達するという。一方、世界原子力協会によると、原発は12月1日時点で3億8225万キロワットとなっている。

FELDHEIM, GERMANY - JUNE 20: Michael Knape, mayor of Treuenbrietzen, which also includes the village of Feldheim, poses for a portrait in a field of barley on June 20, 2011 in Feldheim, Germany. Feldheim recently won recognition from the state of Brandenburg for becoming exclusively reliant on alternative energy sources for its energy needs. It produces electricity and heat at a biogas facility and also draws electricity from nearby wind and solar farms operated by renewable energy supplier Energiequelle GmbH.
