Cities and States Lead on Climate Change

IOWA CITY — THE wind turbines that rise out of the cornfields here reminded me on a recent drive of one postelection truth, even in the red state of Iowa.
As President-elect Donald J. Trump considers whether to break the United States commitment to the Paris climate accord, the rise of clean energy across the heartland is already too well entrenched to be reversed.
By 2020, thanks to MidAmerican Energy’s planned $3.6 billion addition to its enormous wind turbine operations, 85 percent of its Iowa customers will be electrified by clean energy. Meanwhile, Moxie Solar, named the fastest-growing local business by The Corridor Business Journal of Iowa, is installing solar panels on my house, and is part of a solar industry that now employs 200,000 nationwide.
Doomsday scenarios about the climate have abounded in the aftermath of the November election. But responsibility for effectively reining in carbon emissions also rests with business, and with the nation’s cities and states. Those are the battlegrounds. Worldwide, cities produce as much as 70 percent of greenhouse gas emissions.
Many of the planet’s cities lie along the coasts and are threatened by slowly rising seas. Seventy percent of those cities are already dealing with extreme weather like drought and flooding. Add in aging infrastructure and waves of migrants and it is obvious that city planners, mayors and governors have had to re-envision how their cities generate energy and provide food and transportation.
“The concept of a regenerative city could indeed become a new vision for cities,” the Germany-based World Future Council reported recently. “It stands for cities that not only minimize negative impact but can actually have a positive, beneficial role to play within the natural ecosystem from which they depend. Cities have to constantly regenerate the resources they absorb.”
This idea won broad support at a recent gathering of city leaders from around the world in Quito, Ecuador, hosted by the United Nations. The Habitat III conference approved a “new urban agenda” that urges cities to adapt to climate change but minimize their harm to the environment and move to sustainable economies.
In a changing climate, these approaches make sense. As Michael Bloomberg, the former mayor of New York, told the Chinese General Chamber of Commerce recently, “Cities, businesses and citizens will continue reducing emissions, because they have concluded — just as China has — that doing so is in their own self-interest.”
With or without significant federal support, reducing greenhouse gas emissions will require major private investment, as it has here in Iowa, and ambitious private-public initiatives from mayors and governors. We need to activate a new era of “regenerative” cities and states.
California’s recent move to reduce its carbon emissions by 40 percent below 1990 levels by 2030 is a hopeful shift that other cities and states should emulate. This would involve setting high benchmarks for developing green enterprise zones, renewable energy, cultivating food locally, restoring biodiversity, planting more trees and emphasizing walkability, low-carbon transportation and zero waste.
Following this regenerative approach, the Australian city of Adelaide reduced its carbon emissions by 20 percent from 2007 to 2013, even as the population grew by 27 percent and the economy increased by 28 percent. The city experienced a boom in green jobs, the development of walkable neighborhoods powered by solar energy, the conversion of urban waste to compost and a revamped local food industry. The city also planted three million trees to absorb carbon dioxide.
Over 10,000 climate initiatives are underway in cities worldwide, according to the C40 Cities Climate Leadership Group, which represents 80 major cities. In nearby Des Moines, for instance, Mayor Frank Cownie recently committed the city to reducing its energy consumption 50 percent by 2030 and becoming “carbon neutral” by 2050.
Initiatives like those have become a “fill the potholes” reality for many mayors, regardless of political games in Washington. In San Diego, the Republican mayor, Kevin Faulconer, helped to push through a climate action plan that commits the city to 100 percent renewable energy by 2035. Other cities are following his lead.
“Dull, inert cities, it is true, do contain the seeds of their own destruction and little else,” the urban visionary Jane Jacobs wrote. “But lively, diverse, intense cities contain the seeds of their own regeneration, with energy enough to carry over for problems and needs outside themselves.”
In an age of climate change, and a possible shift in the federal government’s priority on climate action, never have those words been truer.

7.5 MW Wind Turbine Construction (Video)
Article by Jake Richardson, Clean Technology, February 17, 2016
If you have any interest in wind turbines, you might enjoy this 3-minute 42-second video showing a huge 7.58 MW Enercon E126 being assembled. The first images are of the enormous circular concrete foundation, which weighs about 2,500 tons, according to text below the video.
These initial shots are informative in that they show some human figures on and near it, which provides a sense of scale. You can also see a number of steel structures that look something like an internal frame. The technology used throughout the video is present here too – very long cranes, sometimes it appears with extensions.
Drone shots are used quite a bit in the video and at about 18 seconds there is a very impressive rotating, rising shot. If you want to more closely examine details in the various construction shots, you can expand the video to the largest size and stop it to look within them. This might be worth doing because in some shots there is a lot of equipment.
You can see why drones with cameras were necessary: the wind turbine’s height is about 650 feet with a rotor diameter of 443 feet. Placing the hub at over 400 feet seems particularly precarious, and watching the workers do it with precision is very impressive.
Considering that wind turbines need to be located in areas with sufficient winds to turn the blades and generate electricity, it almost doesn’t seem possible that extremely long crane arms could be maneuvered so precisely to put all the turbine pieces in place to create the whole structure, but the workers do it.
At about 3:18 there is another scale shot, where you see humans standing and walking on one blade which is on the ground.
The video’s title says the turbine is the most powerful in the world, but that seems to be untrue.
There is a 10 MW offshore turbine and Vestas has an 8 MW turbine.
The video might have been made before these two larger ones became available though. Nevertheless, the video is fascinating to watch if for no other reason than to see humans pulling off what appears to be nearly impossible.
