Common Dreams reports

More than 100 cities across the globe are now mostly powered by renewable energy, a number that has more than doubled over the past three years, according to a review of environmental data collected from entities worldwide.

The new analysis, a tally of information collected by the U.K.-based group CDP [Carbon Disclosure Project] and released [February 27], accounts for towns and cities that get at least 70 percent of their electricity from renewable sources such as wind and solar. In addition to publishing its complete list, the group created an interactive map that features key details about some municipalities' transitions.

While only four U.S. cities made the list--Aspen, Colorado; Burlington, Vermont; Eugene, Oregon; and Seattle, Washington--the group says 58 localities in the United States have committed to a full transition. Among the largest cities on CDP's list are Auckland, New Zealand; Nairobi, Kenya; Oslo, Norway; and Vancouver, Canada. Forty-seven of the cities listed are located in Brazil. More than 40 cities--from Burlington to Reykjavik, Iceland to Basel, Switzerland--are fully powered by renewables.

[...] The new data reflects the rapidly growing trend to commit to a renewable energy transition at a local level. CDP noted in a statement that Tuesday's analysis "comes on the same day the UK100 network of local government leaders announce that over 80 UK towns and cities have committed to 100 percent clean energy by 2050, including Manchester, Birmingham, Newcastle, Glasgow, and 16 London boroughs".

    I was particularly surprised to see only three Norwegian cities on this list; the entire nation of Norway ought to be included.
    From the fine Wiki: [wikipedia.org]

    Norway is known for its particular expertise in the development of efficient, environment-friendly hydroelectric power plants. Calls to power Norway principally through hydropower emerged as early as 1892, coming in the form a letter by the former Prime Minister Gunnar Knutsen to parliament. Ninety percent of hydropower capacity is publicly owned and distributed across municipalities, counties, and states. Nationwide installed capacity of hydropower amounted to 33.8 GW in 2015. The maximum working volume of hydrologic storage power plants is 85 TWh, whereas the average seasonal cycle is 42 terawatt-hours (TWh). In 2015, hydroelectricity generated 144 TWh and accounted for 97.9% of the national electricity demand.

    (emphasis added)

    This article is based on a tally made by the CDP [cdp.net] (a British group that compiles a collection of self-reported environmental data), and it explicitly says it includes hydro as a renewable source, so what gives? Maybe they are only listing cities that give them an report? That's one heck of a selection bias in the data set...
