Al Gore today recommends once again higher taxes and a higher carbon price to cut CO2 emissions. He wants to tax the poor off the roads and let them stay cold in winter. Rather like Maria Antoinette, he would probbaly say "let them walk and wear thicker woolies". There is no mention of incentives and technology, the magic weapons in the battle to reduce our dependence on burning carbon.
Meanwhile, the UK government has decided to take another tilt at windmills. Urging more renewables (a good thing), they are ordering many more wind farms (a more questionable thing). I hope it is windy on Christmas day when we all want to cook our turkeys. It would not be good being told by the electricity industry in 2020 we will have to wait for a windy day to have Christmas lunch.
The government should also audit the carbon needed to make the wind turbines, install them, maintain them and replace broken parts. They should then add in all the carbon expanded to make stand-by plants for days when it is not windy. Then they might see that "wind wind" is not always "win win".
