Environmental Cost Makes Wind Cheaper Than Coal in Europe | MIT Technology Review

24Paźdź14

Surprisingly, solar power fared poorly in the analysis, costing far more than wind power and nearly the same as nuclear power. The reason, says Gardiner, is that many of world’s solar panels are manufactured in China, where electricity is very carbon-intensive. The depletion of metal resources also represents a larger cost for solar than wind, she says. Gardiner notes, however, that solar technology is still improving and may be more cost-effective today than it was in 2012, the year used for the study.

According to the Ecofys analysis, new coal and natural gas plants in the E.U. have levelized costs of just over €50 ($64) (in 2012 euros) per megawatt-hour (assuming they are running at maximum capacity); onshore wind is around €80 ($102) per megawatt-hour; utility scale solar PV is about €100 ($127); nuclear power is around €90 ($115); and hydropower is as cheap as €10.

The chart below shows the estimated environmental cost for several technologies, per megawatt-hour.
