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]

How Apple Became One of the Greenest Companies in America

In Obama's America, according to conservatives, utilities are forced to consume expensive green energy mandated by the government. But in an ideal conservative America utilities would procure the cheapest and most reliable resource to deliver value to consumers. Those worlds have officially collided.[read more]

Life-Cycle Study Confirms Global Environmental Benefit of Low-Carbon Energy Technologies

October 16, 2014 by Roman Kilisek

Low-Carbon Tech Benefits

A new study examines the environmental impacts and resource requirements of large-scale global implementation of a variety of low-carbon power generation tech as backbone of a new low-carbon power supply infrastructure. Basically, this research goes one step further than previous life-cycle assessments.[read more]

​In Defense of LEDs: Why the Rebound Effect for Solid-State Lighting May Be Overblown

October 16, 2014 by Rob Day

Energy Efficiency and Rebound Effects

LED lighting is one powerful tool for addressing climate change. And the people working hard to accelerate adoption of LED lighting should be very proud of what they are doing. We can do even more, too. But to say that LEDs are "unlikely" to make a positive impact on climate change is just not true.[read more]

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]
