As the world continues to make a serious push of the adaptation of clean, long-lasting energy, new data from the Carbon Disclosure Project (CDP) indicates that many cities around the world are supporting the idea.
The CDP report indicates that forty-three cities, from Reykjavik (Iceland) to Addis Ababa (Ethiopia) are currently powered 100 percent by renewable energy, including hydropower, geothermal, solar, or wind.
Brazil, with its extensive dam system, has more than 40 cities on the list, nearly half of which are 100 percent powered by hydro.
Burlington, Vermont is the only U.S. city powered entirely by renewables, using a combination of hydro, wind, solar, and biomass.
Seattle is next, with renewables generating 94 percent of its electricity, followed by Eugene, Oregon at 89 percent and Aspen, Colorado at 74 percent.
CDP attributed the increase in cities’ renewable energy usage to both more municipalities sending data to the organization, as well as a global shift toward less carbon-intensive energy sources.
“Cities are responsible for 70 percent of energy-related CO2 emissions,” said Kyra Appleby, CDP’s director of cities.
“Reassuringly, our data shows much commitment and ambition. Cities not only want to shift to renewable energy but, most importantly, they can.”
But Brazil has been cautioned on the dangers of over-reliance on hydropower.
“We’ve seen the production of electricity from hydropower drop drastically from one year to the next due to drought in some Latin American regions,” she said.
“Cities in the developing world, especially in Latin America, are beginning to understand the need for diverse energy for truly sustainable power generation that truly considers the local environment and population.”
