Home Energy Use and Savings

Today’s consumers have more tools at their disposal than ever for reducing consumption, managing energy, and generating power. New residential-focused technologies, cost reductions, and business models are creating opportunities for advanced energy companies while saving money for homeowners.[read more]

Advanced Energy Technology of the Week: Offshore Wind Power

March 6, 2015 by Maria Robinson

Offshore Wind

Offshore wind turbines are located on bodies of water where there is access to stronger wind resources than are typically available on land. These turbines convert the kinetic energy of the wind to electricity with no greenhouse gas emissions. Generally, these turbines are fixed directly to the sea floor.[read more]

Beyond Technology Tribalism

Tribalism is the biggest problem with clean energy debates today. Support for one tech is interpreted as opposition to another, and attempts to grapple with any tech’s challenges are dismissed as trolling. Getting past this requires honest engagement on the promises and perils of different technological pathways.[read more]

Utility-Scale Solar

Solar PV has driven large expansions in U.S. utility-scale solar power installations over the last decade, such that solar was the second largest source of new electric capacity added in 2013. Nearly 2,900 MW of new utility-scale solar was installed in 2013, a 58% increase from 2012.[read more]

Tonio Buonassisi Seeks to Make Solar Cells Competitive

January 15, 2015 by Energy @ MIT

Solar Cells and Market Competitiveness

One day, as he was riding home from high school in São Paulo, Tonio Buonassisi looked out the bus window at the city’s long lines of traffic, and its smoggy haze. It was then he realized that there had to be better ways for people to produce and use energy, and that he wanted to try to do something about it.[read more]

Solar Energy Absorber Tech

The key to creating a material that would be ideal for converting solar energy to heat is tuning the material’s spectrum of absorption just right: It should absorb virtually all wavelengths of light that reach Earth’s surface from the sun — but not much of the rest of the spectrum.[read more]

High-Flying Turbine Produces More Power

May 16, 2014 by Energy @ MIT

Airborne Wind Energy Turbine

For Altaeros Energies, the sky’s the limit when it comes to wind power. Founded by Ben Glass and Adam Rein, Altaeros has developed the first commercial airborne wind turbine, using a helium-filled shell to float as high as a skyscraper and capture the stronger, steadier winds available at that altitude.[read more]

Straight Talk About Radical Climate Change, And How To Stop It
