Abandoned Solar Energy Project Highlights Pitfalls of Tax Uncertainty

October 20, 2014 by Tom Carlson

Solar and Tax Risk

In the latest evidence of the need for stable federal tax policy, a major solar project in California was abandoned in part due to uncertainty around whether the project would be placed in service in time to qualify for the investment tax credit, which expires at the end of 2016.[read more]

Defense and Climate Risk

The Department of Defense released its 2014 Climate Change Adaption Roadmap on Monday, outlining how the U.S. military plans to adapt to the impacts of climate change. For the first time, the Pentagon discusses climate change as an immediate risk.[read more]

Innovation Needed for Gas to Bridge to Somewhere

October 20, 2014 by Alex Trembath

Natural Gas and the Future of Energy

A new research letter in Nature concludes that natural gas will not “discernibly reduce fossil fuel CO2 emissions.” The paper models a scenario in which the US shale gas revolution is scaled globally. While natural gas displaces higher-carbon coal-fired power, zero-carbon power like nuclear and solar are also displaced.[read more]

How Microsynchrophasors Could Keep Solar-Saturated Grids Stable

Solar Energy and Stable Grids

The electricity from rooftop solar PV is very different from conventional electricity. It sags and surges in response to the pattern of clouds crossing overhead, and is also provided by lots of inverters, which create electrical conditions very different from the alternating current supplied by big spinning generators.[read more]

Georgia Is the Latest State to Procure Dirt-Cheap Solar Power

Comparing Capacity

Capacity comparisons look great in that they can make it appear that vast amounts of renewable energy is entering the energy mix when that is not the case. Renewable energy will undoubtedly have its day, but a generation or two will likely have to pass before we can note its significant impact.[read more]
