Copenhagen to be 1st Carbon Neutral City by 2025 and Other Wind Energy Good News Stories

Juan Cole

Wind power is falling rapidly in cost, with turbines becoming bigger and more efficient.

Nice article. I just want to point out for those that don’t realize - the numbers than Juan Cole is reporting are for peak power - not average power produced over a year. Wind power was a huge surprise to me as I thought Solar power was going to save us when I was a kid. But if you look at renewable energy plans for the US (e.g. @PaulSwanee1 pointed me to one I like a lot, but the full text is quite long - I’m not even remotely through it - the summary at https://www.vox.com/2015/6/9/8748081/us-100-percent-renewable-energy is an easy read - they also have a list of renewable energy articles which I’ll probably check out at https://www.vox.com/renewable-energy) you will see very large numbers for on-shore + off-shore wind. In the linked article, they make up a full 50% of produced power or about 0.8 TW. This number is power averaged over the year.

If you look at https://en.wikipedia.org/wiki/Wind_power_in_India, you will see India does have 34 GW peak power installed and as they get 52,666 GWh over a year out, the average power = 52,666/(24*365) = 6 GW (or a capacity factor of 17%).

What! No California cities on the top of the list? We are laggards once again.
I thought there was a state /city in the southwest that was on their way also.

People continue to think it’s the production of electricity that is the big threat,
but it’s cars, trucks, air travel, shipping and wars that are the main culprits.
Stop shopping, stay home, and grow a garden if your local climate isn’t already ruined.

Copenhagen is about 3 miles across, so bicycling might be fine. It also has a population of about 600,000. Their main economy is tourism and commerce same goes for the whole of Denmark, with no major industry to speak of. It’s kinda easy to be “carbon neutral”. Same like Costa Rica.
