A Tale of Two Cities: How San Francisco and Burlington Are Shaping America's Low-Carbon Future
By Kyra Appleby
President Trump's commitment to pull out of the Paris agreement signaled what appeared to be the worst of times for a transition to a low-carbon future in the United States. But actions being taken by a significant number of cities could instead make it the best of times for renewable energy in America.
Cities both in the U.S. and around the world are increasingly setting low-carbon goals and implementing local policies that recognize sustainability investment as essential to new markets, jobs and creating attractive places to live, work and do business.
New research released last month by CDP, a U.K.-based charity that runs the global disclosure system for businesses and governments, showed more than 100 global cities that report that they are getting at least 70 percent of their electricity from renewable sources.

In the U.S., 58 cities and towns have now committed to transition to 100 percent clean, renewable energy, including big cities like Atlanta and San Diego. Earlier this year, U.S. municipalities Denton, Texas and St. Louis Park, Minnesota, became the latest communities to establish 100 percent renewable energy goals.
In June 2017 the U.S. Conference of Mayors, representing 250 U.S. mayors, resolved to support the procurement of 100 percent renewable energy for cities by 2035.
Burlington's Bold Breakaway
Burlington, Vermont is one of the first U.S. cities to report to CDP that it sources 100 percent of its electricity from renewable sources.
Burlington began its transition to a net-zero economy back in 1978 when it replaced its coal plant with a 50-MW generating station powered on biomass. The next step was harnessing wind and solar power through the construction of a 10-MW wind farm and the installation of rooftop solar PVs on high schools, the airport and the electric department. In 2014, when citizens voted to approve a $12 million bond in 2014 for the city's energy department to purchase the 7.4-MW Winooski Hydroelectric Plant, Burlington's transformation to 100 percent renewable energy was complete.
The city's shift to green energy has also helped its residents, not raising electricity rates in eight years. And seizing the opportunity to turn Burlington into a center of innovation, the city has continued its progressive push by investing in charging stations for electric vehicles and developing plans to pipe steam from the biomass plant to heat downtown homes.
Solar San Francisco
Three thousand miles away on America's west coast, San Francisco is trailblazing the path in solar power—driven by economic reality. Last year, municipal leaders took the bold move to become the first American city to mandate solar roofs on most new construction. Under the legislation, all new buildings under 10 stories must have solar PV or solar thermal panels installed on at least 15 percent of their roof space. Consequently, the city now boasts more than 15-MW of solar PV.
With an electricity mix of 34 percent renewable energy, San Francisco still has a long way to go to reach its ambitious target of 100 percent by 2030. But the wheels are clearly in motion to scale-up solar power, with the city serving as a shining example of the power of solar.
Unsubsidized renewables were the cheapest source of electricity in 30 countries last year according to the World Economic Forum. With renewables predicted to be consistently more cost effective than fossil fuels globally by 2020, the rate at which cities around the world follow San Francisco's lead is likely to pick up pace.
Cities as the Battleground
Cities are vital to the transition to a low-carbon economy. Cities are home to half the world's population and are expanding rapidly. In the U.S. alone, over 80 percent of the population lives in urban areas. Meanwhile, cities around the globe are responsible for over 70 percent of energy-related carbon emissions.
As cities expand, they need to ensure that the new infrastructure they put in place is fit for a low-carbon economy. Public-private partnerships will be crucial to transitioning to green energy, particularly with the propensity for deficits in public finance.
The good news is that CDP's data shows that globally, cities are moving in the right direction in engaging with the private sector. In 2016, we collected data from 570 cities around the world and found that municipalities highlighted a total of 720 climate-related projects suitable for private sector investment, worth a combined $26 billion. One year later, that figure had ballooned to 1,045 projects and more than $52 billion.
Much of the drive behind city climate action and reporting comes from the 7,000+ mayors signed up to the Global Covenant of Mayors for Climate and Energy who have pledged to act on climate change.
Despite the prospect of the American withdrawal from the Paris agreement, cities in the U.S. and around the world are still putting ambitious plans in place to harness the power of clean electricity. Cities not only want to shift to renewable energy, but most importantly, they can. We urge all cities to disclose to us, work together to meet the goals of the Paris agreement and prioritize the development of ambitious renewable energy procurement strategies.

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

Kokia drynarioides is a small but significant flowering tree endemic to Hawaii's dry forests. Native Hawaiians used its large, scarlet flowers to make lei. Its sap was used as dye for ropes and nets. Its bark was used medicinally to treat thrush.
States that invest heavily in renewable energy will generate billions of dollars in health benefits in the next decade instead of spending billions to take care of people getting sick from air pollution caused by burning fossil fuels, according to a new study from MIT and reported on by The Verge.
Hawaii's Kilauea volcano could be gearing up for an eruption after a pond of water was discovered inside its summit crater for the first time in recorded history, according to the AP.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.
Humanity faced its hottest month in at least 140 years in July, the US National Oceanic and Atmospheric Administration (NOAA) said on Thursday. The finding confirms similar analysis provided by its EU counterparts.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.
It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
