Cities can drive better economic growth while also reducing climate risk. They are at the forefront of the fight to protect the climate and eradicate poverty, and are often trailblazers in a world in which nation states typically move more slowly to address global challenges. These are the crucial conclusions from a series of studies released this week by the Global Commission on the Economy and Climate, which draws from examples worldwide, including cities as diverse as Lima, Peru and Leeds, UK.
The future is tough to predict. The International Energy Agency recently came out with its World Energy Outlook 2014, a comprehensive analysis of global energy demand and the underlying supply mix through 2040. Along with BP’s annual forecast, it is one of the most authoritative documents of i
In America’s low-carbon future, most cars will run on electricity, carbon dioxide will be stored underground, and homes and buildings will be hyper-efficient, guzzling less energy even as the population grows. This is the vision of a new analysis that maps how the United States can drastically curb its greenhouse gas emissions by 2050. TheRead More
By Justmeans by RP Siegel SOURCE: Justmeans DESCRIPTION: We have seen impressive growth in renewables over the past several years, but much of that growth is based on the somewhat shaky foundation of continuing subsidies. So argues Eduardo Porter in the New York Times. Porter points out that while wind power added 13 GW ofRead More
As I was recently dulling blades while chopping switchgrass for some experiments, I started thinking whether the “high yield perennial grasses on marginal land” paradigm makes any sense for biofuels. There are many positives about using perennial grasses. They are low maintenance, high y
While many are prophesizing the Environmental Protection Agency’s Clean Power Plan (CPP) as doomsday for the electricity sector, Texas utilities are telling a different story. The CPP will limit – for the first time ever – carbon emissions from existing power plants. One utility in particular, CPS Energy in San Antonio, “has already embraced aRead More
Creating a sustainable long-term distributed photovoltaic (DPV) market will require aligning the interests of utilities, solar companies, technology providers, and customers. Read our latest report diving deep into how this can be done.
Solar and energy storage will increasingly be integrated together at commercial sites, homes and microgrids. But to be honest, they are an odd couple with very different personalities. Solar is passive: solar modules are typically planted in a fixed position to generate power for 20 or 30 years. You
Brazil’s Jaguari reservoir has fallen to its lowest level ever, laying bare measurement posts that jut from exposed earth like a line of dominoes. The nation’s two biggest cities are fighting for what little water is left.
It’s been widely publicized that the cost of residential solar electric systems in the United States is falling faster than ever before. This downward pricing trend is projected to continue through 2016 and then stabilize, according to a September 2014 report compiled by researchers
