Excitons Observed in Action for the First Time

April 19, 2014 by Energy @ MIT

Solar Tech Advancements

A quasiparticle called an exciton — responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits — has been understood theoretically for decades. But exciton movement within materials has never been directly observed.[read more]

The EPA Gives Us 25 Ways to Limit Climate Change

April 19, 2014 by Sarah Battaglia

The earth is getting warmer. There’s no doubt about that. The average temperature of our planet rose 1.4°F over the last 100 years, and is expected to continue on that path over the next 100 years. Some are even predicting an increase by as much as 11.5°F.[read more]

Loan Guarantees Are Back: DOE Targets 'Catalytic' Grid Integration Technology

Efficiency and Competitiveness

United States Representative Matt Cartwright recently introduced the Job Creation through Energy Efficient Manufacturing Act (H.R. 4162), which would encourage the use of energy efficient technologies in the manufacturing sector of the economy.[read more]

German Demand Response: Almost Ready for Prime Time

April 16, 2014 by Katherine Tweed

When the wind blows and the sun shines in Germany, electricity prices in the country plummet. Natural gas peaker plants are not needed, as the peaks are erased and they cannot compete with renewables. But the grid still needs a lot of balancing resources during times that renewables dominate.[read more]

Renewables and Nuclear Cooperation

Nuclear power and variable renewable energy sources like wind and solar power “don’t play well together.” The more I think about this, however, the more I’m convinced that the accepted wisdom that renewables and nuclear mix like oil and water is true only up to a point.[read more]

Emissions Mitigation

Today we see a huge focus on renewable energy and energy efficiency as solutions for reducing CO2 emissions and therefore addressing the climate issue. Yet such a strategy may not deliver the outcome people expect and might even add to the problem, particularly in the case of efficiency.[read more]

Solar Energy, Sky Cameras, and Hard Math: A New Way to Integrate PV on the Grid

April 14, 2014 by Jeff St. John

Sky Cameras and the Grid

Insanely complex math, and never enough data -- that’s the conundrum in trying to model the ebb and flow of solar power and energy storage on the grid edge. Large-scale transmission systems are well modeled. But the majority of the grid below the substation provides little to work with.[read more]

To assess the re-emergence of climate change as a topic of intense public discussion, I sat down with Eric Maltzer, who for four years worked on clean energy and global climate policy at the US State Department. Our hour-long conversation covers a wide range of topics.[read more]

Catalyzing the Climate Change Conversation with Eye-Catching Headlines

April 14, 2014 by Jenny Tang

The latest IPCC report has been covered by US and international media, and in the major media the story has achieved powerful headlines. Thus, the intensity of the media coverage begs the question – what has changed? Why has this report gained so much traction where previous reports failed?[read more]
