Future Cities Need 'Intelligent' Local Energy Systems

November 28, 2014 by Sophie Curtis

Urban Energy Systems

In cities we are faced with systems of multiple spatial as well as temporal scales. Slowly changing urban infrastructure systems are required to react to sometimes rapid societal changes. In addition cities bring together a large variety of different stakeholders their own specific viewpoints.[read more]

Does Texas Need a Carbon Tax to Meet EPA Climate Rules?

November 27, 2014 by Katherine Tweed

The Texas grid has (mostly) kept the lights on despite having minimal reserve margins for years. But if ERCOT, which operates the state’s grid, implements the U.S. Environmental Protection Agency’s proposed Clean Power Plan to cut carbon dioxide emissions, it will reduce grid reliability in the state even further.[read more]

Solar Install Pricing Drop

Between 2012 and 2013, global investment in climate change mitigation and adaptation dropped $28 billion. When scientists say we need a dramatic surge in zero-carbon energy sources, the drop seems like bad news. It's certainly not good by climate action standards. But it's not as bad as it sounds either.[read more]
