Boris Johnson infamously once wrote that wind power can barely “pull the skin off a rice pudding.” At the time of writing, his perspective has changed, and speaking as Prime Minister of the United Kingdom he is suggesting that every home might be powered by wind turbines by the year 2030. There remains much work to be done to realize such visions, which are widespread among other leaders looking for renewable, sustainable, and zero-carbon energy sources in the face of climate change and uncertain fossil fuel security in coming years.
