Aspen, Colorado swaps coal for wind to become 3rd city to run solely on renewable energy

Fossil fuel dependency is now a thing of the past for this municipality on Colorado's Western Slope. Aspen has just announced that it's only the third city to kick the habit and is fully reliant on renewable energy sources. Earlier this month, the Aspen Times reported that the city had reached the landmark after it signed a contract with electrical energy provider Municipal Energy Agency of Nebraska. As part of this process Aspen swapped coal for wind power to make up for the non-renewable energy deficit with its energy also coming from hydroelectric, solar, and geothermal. Prior to this, Aspen had been running on an estimated 75 to 80 percent renewables. The feat was also able to be realized due to the recent drop in solar energy prices. In fact, the cost of solar energy is predicted to fall further still, dropping below $0.50 per watt in the next few years. Solar energy is not alone in this trend. In what's a good economic indicator of renewable energy's growing popularity, wind power is also much cheaper than it was just a decade ago. This trend toward renewables was likely aided by Obama's carbon regulations which made renewable energy alternatives increasingly competitive against fossil fuel sources such as coal. According to ThinkProgress, "already, more than one-third of American coal plants have been shuttered in the past six years, and the new carbon rules make it quite possible that no new coal plants will ever be built in the United States." “It was a very forward-thinking goal and truly remarkable achievement,” Aspen's Utilities & Environmental Initiatives Director David Hornbacher said. “This means we are powered by the forces of nature, predominately water and wind with a touch of solar and landfill gas. We’ve demonstrated that it is possible. Realistically, we hope we can inspire others to achieve these higher goals” Renewable energy has long since been on Aspen's agenda going back to the 1980s with the Reudi and Maroon Creek hydroelectric projects. Highlighting the accomplishment, former Project Coordinator Will Dolan said Aspen only began working toward its goal of 100 percent renewable energy about a decade ago. Beating Aspen to the 100 percent renewable landmark were Burlington, Vermont and Greensburg, Kansas.

New SimCity “Green Utopias” Offer Futuristic Glimpse of Imagined Cities

In 50 to 75 years, SimCity, the virtual city-building game just about every architect or planner has played around with at some point, imagines an average metropolis taking two routes—a sustainability-based, green utopia or a money-driven, oil-dependent corruption—and gives players the tools to construct these futures. Slated for release in the United States on November 13th, Cities of Tomorrow, the new SimCity expansion pack, allows players to engage in futuristic urban planning using imagined versions of current technology. Elevated Maglev trains transport passengers high above congested vehicle traffic; drones deliver packages and prevent neighborhood crime; high-rise “MegaTowers” become mixed-use complexes with customizable retail, residential, education, and solar energy plant levels. However, PSFK reports that unlike previous editions of the game, the Cities of Tomorrow expansion requires its virtual city planners to consider the tradeoffs of their architecture and urban construction efforts. Source and type of energy for power will determine the government and pollution level of each town and consumerism and lure of cheap labor can overcome clean, sustainable methods for maintenance of each urban environment.
