New Biofuel Approach

Yeast is commonly used to transform corn and other plant materials into biofuels such as ethanol. However, large concentrations of ethanol can be toxic to yeast, which has limited the production capacity of many yeast strains used in industry.[read more]

Lasers, Circuit Boards, and a $30 Gizmo: Innovative Solutions to the Methane Problem

September 20, 2014 by EDF Energy Exchange

Methane Problems and Solutions

The technologies we see today didn’t all start out in the forms we’re used to. The phones we carry in our pockets used to weigh pounds, not ounces. Fast forward and now we're looking at a drunk-driver-and-alcohol sensor that was converted into a methane leak detector.[read more]

Technology Advances Wind Energy Development

September 18, 2014 by Dan Liggett

Wind Energy and Tech

There have been significant improvements of late to equipment used to produce energy from wind. Towers are taller. Rotor diameters and blades are longer. Gearboxes, generators and bearings are more reliable. Onboard sensors are more effective at measuring and recording data.[read more]

Advanced Energy Technology of the Week: District Energy

September 12, 2014 by Matt Stanberry

District Energy

District energy systems produce steam, hot water, and/or chilled water at central plants and, through a network of insulated pipes (often underground), distribute the steam or water to multiple buildings. District energy plants often include power generation, typically CHP, which further increases overall efficiency.[read more]

Advanced Energy Technology of the Week: Demand Response

Demand Response Tech

Demand Response is a mechanism that allows utilities to provide customers with information and incentives that encourage customers to reduce energy usage at specific times of the day or year. This gives customers more control over their energy usage and costs.[read more]

Advanced Energy Technology of the Week: Efficient Building Insulation

August 14, 2014 by Matt Stanberry

Building Insulation and Loss Prevention

One key building material that greatly impacts the efficiency of a building is insulation. Up to 45% of a building’s heat can be lost through the roof. The effectiveness of insulation can be determined by its thermal resistance, represented by R-value.[read more]

Technologies Meld As History Repeats Itself

December 10, 2013 by Christine Hertzog

The Smart Grid is often described as bi-directional energy and information flows, enabled by a convergence of information technologies with operational technologies. That’s all true, but the word convergence is getting frayed from overuse, and for the latest trend, it’s not quite the right word.[read more]

Innovative Solutions Target the Energy/Water Nexus

December 3, 2013 by Christine Hertzog

My Thanksgiving list put contemporary entrepreneurs at the top. Their efforts are paying off in the improvements in renewable energy harvesting technologies, increasing the range of cost-effective energy storage technologies, and addressing important environmental and social issues.[read more]

Big Bets in Energy Technology From "Beyond Petroleum"

October 31, 2013 by Rod Adams

BP and Energy Technology

As an energy industry observer with a long memory, I was somewhat bemused by a recent interview aired on Platts Energy Week. Bill Loveless sat down with David Eyton, BP’s head of technology, to talk about the exciting new technologies that his company is developing.[read more]

What could generate a standing room only crowd in an upscale hotel in Menlo Park? Talk about the past, present, and future of energy consumption data, which is tremendously enabled by Smart Grid technologies.[read more]

The Ethanol Urban Myth

June 23, 2010 by Jane Van Ryan

Last weekend I was having a very pleasant conversation with my neighbors when the subject turned to the oil spill and the need for alternative energy. One neighbor said, "The oil companies don't want us to use alternative energy so they've bought all of the best technologies." You've probably heard that old saw. It's one of several "...[read more]

How Energy Efficiency Will Put Us On The Moon

October 8, 2009 by Peter Troast

A recent column from Thomas Friedman drew a lot of attention, declaring as it did that 1) clean energy is the Sputnik of our era, 2) China is overtaking us in what Friedman calls "E.T." (energy technology) investment, and 3) if we neglect to realize the importance of E.T., we can kiss our global leadership hat goodbye.  ...[read more]

The Energy Technology Olympics

July 6, 2009 by Jake de Grazia

One thing that consistently made me uncomfortable when I lived in China was everyday nationalism. And one thing that consistently makes me uncomfortable now that I live in the USA again is everyday nationalism.Community-level cultural solidarity I feel. Planet-scale compassion I feel. Drawing boundaries between Americans and Chinese and...[read more]
