New Kind of "Tandem" Solar Cell Developed

March 28, 2015 by Energy @ MIT

Solar Cell Invention

Researchers have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations.[read more]

Emerging Technologies Can Pave the Way for Time-Variant Electricity Pricing

March 27, 2015 by EDF Energy Exchange

Variable Electricity Pricing and Tech

The amount of energy we use at any given time is constantly changing. Lights are switched on and off by time of day, appliances operate based on the season. In order to meet our dynamic energy demands, our system has to have the infrastructure and resources in place to respond when needed.[read more]

March 27, 2015 by Deborah Lawrence

We have all heard of the “shale revolution." It has been touted as the energy panacea of our time. Given the extreme hype, one would expect that such enthusiasm would translate into above average share performance for shale operators. This has not been the case.[read more]

U.S. Biodiesel and Renewable Diesel Imports Decline 36% in 2014

March 27, 2015 by U.S. EIA: Today in Energy

U.S. Fuel Imports

After reaching record levels in 2013, U.S. imports of biomass-based diesel fuel (both biodiesel and renewable diesel) fell 36%, to 333 million gallons in 2014. Uncertainty surrounding Renewable Fuel Standard targets and the absence of a late-year influx of volumes from Argentina were two main factors in this decline.[read more]

The Secret to Cost Effective Energy Storage

March 27, 2015 by Nigel Morris

I am as optimistic as anyone about energy storage and try as I may I can’t (in my own head) separate the growth in electric vehicle sales and the inevitable flood of lower cost energy storage for stationary applications. There are deep and close connections that will flow both ways.[read more]
