- There is no doubt that wind power reduces CO2 emissions

This was written by Kristoffer Rypdal in a contribution to the debate in the VG newspaper on 24 October. Dr. Rypdal is a professor with the UiT – Norway's Arctic University and of the opinion that Hogne Hongset presented erroneous, flimsy and unserious claims in his article in VG two days earlier.

It was the government's decision to shelve the national wind power framework that was the precursor to the articles. Dr. Rypdal points out that Mr. Hongset is making false claims when he asserts that reduced emissions in Germany in recent years are due to the replacement of coal with gas and that this was caused by increased quota prices. Mr. Hongset also claimed that wind power had not contributed to the decline, because the growth of newly installed wind power had been lower in 2017 and 2018 than in the preceding years.

Dr. Rypdal refers to BP Statistical Review of World Energy, which looks at primary energy consumption of oil, gas, coal, solar and wind power: oil has declined from 119 to 113, gas from 77 to 76, coal from 71 to 66, solar power has increased from 9 to 10 and wind power from 23 to 25. With this in mind, Dr. Rypdal demonstrates that the decline in coal consumption may be explained by increased wind power production. “Since coal power plants has an efficiency factor of only forty percent, two Mtoe from wind will produce just as much electric power as the five Mtoe from coal”, he writes, and continues: “Half the emission declines are due to reduced oil consumption, whereas the other half may be attributed to increased wind power production”.
