A New Dawn for Energy Efficiency Financing

September 16, 2015 by Clare Taylor

Energy Efficiency Financing

Energy efficiency remains one of the most stubborn energy transition challenges. The money is on the table, but the market is yet to take off. Now a ground-breaking project is developing standardized processes for bankable projects on a massive scale. Is investor confidence the key to unlocking the world’s ‘first fuel’?[read more]

US Energy Future - Energy Efficiency, Wind, Solar and Nuclear Energy

August 27, 2015 by Willem Post

The U.S. could achieve a 50% reduction of primary energy via energy efficiency measures, and build-outs of wind and solar systems, so that the energy available to provide for the residential, commercial, industrial, and transportation energy requirements remains nearly unchanged.[read more]

Energy Efficiency: The Building Block for Clean Power Plan Compliance

August 11, 2015 by NRDC Switchboard

One change between the proposed version of the Clean Power Plan rule and the final version, released last Monday, was the removal of energy efficiency as a "building block." The emissions-reducing impact of energy efficiency programs was not factored into final power plant carbon pollution limits.[read more]

UN Sustainable Energy Goals Falling "Substantially Short"

May 22, 2015 by Katherine Tweed

Energy Transition and Developing Economies

Although renewable energy is the fastest-growing portion of new electricity generation in many countries, its rate of growth is still not fast enough to meet the UN goals and unseat legacy sources of generation, primarily coal.[read more]

Untapped Incentives for Energy Efficiency Projects

December 24, 2014 by EDF Energy Exchange

Energy Project Incentives and Support

As an EDF Climate Corps fellow back in 2013, one task that was of particular interest to me was figuring out how to help my host organization fund, in whole or in part, its efficiency upgrades. In my research, the most unique funding source I found was the energy efficiency forward capacity market.[read more]

Is Small-Scale GTL the Next Big Thing?

November 7, 2014 by Edward Dodge

Small-Scale GTL Growth?


Converting natural gas to liquid fuels using Fischer-Tropsch conversion is not a new idea but it has always required very large and expensive production facilities. Now Velocys is bringing to market new technology for small-scale GTL production at a fraction of the capital costs of traditional plants.[read more]

Why Having A Realistic View of Energy Efficiency Matters to Climate Change

Energy Efficiency and Climate Change

In response to our New York Times op-ed about the limits of energy efficiency and the furious reaction to it from some quarters, Andy Revkin asks whether we can find room for agreement on the rebound effect. And to some degree we already have.[read more]


Will LEDs Trigger Rebound Effects? Examining the Key Evidence

November 3, 2014 by Jesse Jenkins

Rob Day argues that the rebounds in energy demand triggered by energy efficient lighting have been overblown. This rebuttal sets the record straight, and does so by exploring the key evidence in the debate over the magnitude of rebound effects.[read more]

Is Energy Efficiency a Good Thing Even with Rebound?

October 28, 2014 by Gernot Wagner

Efficiency and the Rebound Effect

Lighting is highly critical to our livelihoods. Humans have been using lighting technology since long before the advent of industrialization. For many centuries, this lighting was extremely inefficient, with over 95% of the energy consumed wasted as heat.[read more]

International Scorecard Highlights Room for Improvement in Energy Efficiency

July 27, 2014 by NRDC Switchboard

International Energy Efficiency

A recent scan of energy efficiency in 16 nations showed that all fall short of their potential. But the collective wisdom among these countries offers a path forward. Following close upon their World Cup win in Brazil, Germany also comes in first in the latest International Energy Efficiency Scorecard.[read more]

Steam from the Sun

July 22, 2014 by Energy @ MIT

Steam and New Materials

A new and innovative material structure developed at MIT generates steam by soaking up the sun. The structure, which consists of a layer of graphite flakes and an underlying carbon foam, is a porous, insulating material structure that floats on water.[read more]

A New Way to Harness Waste Heat

May 22, 2014 by Energy @ MIT

Saving Waste Heat

Vast amounts of excess heat are generated by industrial processes and by electric power plants; researchers around the world have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused on thermoelectric devices.[read more]

An Energy Efficiency Parable

May 21, 2014 by Catherine Wolfram

Energy Efficiency Challenges

Here’s a story that captures a lot of the challenges, organizational and technical, that we face as we try to implement and improve energy efficiency. Spoiler alert: it doesn’t exactly have a happy ending, but I’m certainly holding out hope for a sequel to the story.[read more]

Leadership for Energy Efficiency

November 25, 2013 by Sadhbh Ní Hógáin

Efficiency Leadership

In conversation, Rod Janssen, long-term consultant to the European Council for an Energy Efficient Economy (eceee) talks about the Recast EPBD, low energy buildings, and the important need for true strong leadership on energy efficiency.[read more]

Are Solar Panels Facing the Wrong Direction?

November 16, 2013 by Katherine Tweed

Solar Panels and Efficiency

West-facing rooftop solar panels produced 49 percent more electricity during peak demand compared to south-facing panels, according to a new study. The research is the first of its kind to evaluate the energy production of solar panels oriented in different directions.[read more]
