A traffic light timing study is under way, and new plans could be implemented early this year, city officials said in December.

Oak Ridge Today asked about the signal timing project during a December interview with Oak Ridge Electric Director Jack Suggs and Jon van Eek, power utilization program supervisor in the Oak Ridge Electric Department. That interview focused on radar-based traffic detectors at six intersections in Oak Ridge.

The City of Oak Ridge announced in September 2014 that it had been awarded a Tennessee Department of Transportation grant for $237,500 for a signal timing optimization project.

Suggs and van Eek said the timing study is under way, and they hope to have new plans implemented after January 1, 2016. The plan is to move the maximum number of cars in all directions and to move the maximum number of vehicles, Suggs said. [Read more…]

Oak Ridge has been recognized as a Green Power Community of the Year by the U.S. Environmental Protection Agency.

Oak Ridge is one of only two cities to receive the award. The other is Medford, Oregon.

Oak Ridge is one of 19 Green Power Partners and four suppliers from across the country receiving Green Leadership Awards given each year by the EPA. Awardees are recognized for their achievements in advancing the nation’s renewable energy market and reducing greenhouse gas emissions fueling climate change, a press release said.

The 2014 Green Power Leadership Awards will be presented on Wednesday, December 3, at the annual Renewable Energy Markets Conference in Sacramento, California. [Read more…]

EQAB Climate Action Plan: Oak Ridge reduces emissions, electrical use

The first progress report for Oak Ridge’s Climate Action Plan said greenhouse gas emissions associated with energy use in city buildings are down and so is the annual electrical consumption for the average household.

Traffic signals use about 60 percent less electricity because of LED bulbs, and Oak Ridge has finished a home energy retrofit demonstration project that could be used as a model in the city, the report said.

Meanwhile, Oak Ridge has been recognized as a renewable energy leader by the Tennessee Valley Authority and is the first Green Power Community in Tennessee and in part of the Southeast. [Read more…]

Grant for signal optimization

The City of Oak Ridge has been awarded a Tennessee Department of Transportation grant for $237,500 for a signal timing optimization project, and TDOT Commissioner John Schroer recently presented the award to Mayor Pro Tem Jane Miller in Nashville.

The signal timing optimization grant is funded by the Congestion Mitigation and Air Quality Improvement Program, or CMAQ, which supports transportation projects that reduce air emissions from on-road sources and non-road sources, as well as projects that reduce traffic congestion, a press release said.

“The city is pleased to receive this grant which will significantly enhance air quality and reduce congested roadways,” Oak Ridge City Engineer Steve Byrd said in the press release.

The signal timing optimization project will target 26 traffic signals on Illinois Avenue, Oak Ridge Turnpike, and Lafayette Drive. The program will synchronize these lights in order to improve traffic flow, reduce congestion and vehicle idling, and decrease commuter travel time. [Read more…]

Featured at Obama speech, Sleek SuperTruck saves fuel, money

Tractor-trailer prototype uses probe developed by ORNL for better gas mileage, cleaner exhaust

It’s a sleek, aerodynamic freight-hauling machine. With its wide tires, rounded edges, and body parts that hug the ground, this million-dollar prototype looks like it could be at home on a race track.

It’s already achieved celebrity status, serving as the backdrop for President Barack Obama during a February speech on greenhouse gas emissions and fuel efficiency standards.

But the SuperTruck is more likely to end up hauling meat and potatoes from Boise to Boston.

The fuel-efficient SuperTruck, the result of a four-year collaboration between the trucking industry and the federal government, made a pit stop at Oak Ridge National Laboratory on Tuesday.

Still, researchers have reason to celebrate. On Tuesday, they said the high-tech tractor-trailer has increased fuel efficiency by 75 percent. Fully loaded, the SuperTruck can drive 10.7 miles on a gallon of gas. That compares to an industry average of 5.8 to 6.5 miles per gallon.

“This is a really big deal,” said Claus Daniel, deputy director of sustainable transportation projects at Oak Ridge National Laboratory, where the SuperTruck made a pit stop on Tuesday.

It’s the result of a collaboration between the trucking industry and the U.S. Department of Energy. It’s not clear how soon the new technologies tested in the Cummins/Peterbilt tractor-trailer, which was built in Denton, Texas, will show up on the nation’s highways. [Read more…]

Vertimass licenses ORNL biofuel-to-hydrocarbon conversion technology

Vertimass LLC has licensed an ORNL technology that converts ethanol into a hydrocarbon blend-stock for use in transportation fuels. ORNL inventors (from left) Chaitanya Narula, Brian Davison, and Martin Keller display the technology with Vertimass chairman William Shopoff.

Vertimass LLC, a California-based start-up company, has licensed an Oak Ridge National Laboratory technology that directly converts ethanol into a hydrocarbon blend-stock for use in transportation fuels.

The ORNL technology offers a new pathway to biomass-derived renewable fuels that can lower greenhouse gas emissions and decrease U.S. reliance on foreign sources of oil.

“Vertimass is very pleased to be partnering with ORNL to commercialize this revolutionary technology that can broaden the market for alternative fuels, ” said Vertimass chairman William Shopoff. “We have assembled a team of industry and technology leaders, including Dr. Charles Wyman, our president and CEO, who will take this novel catalyst from the lab to the marketplace. We see this technology as a significant step in moving the United States toward energy independence.”

The technology developed by ORNL’s Chaitanya Narula, Brian Davison and Associate Laboratory Director Martin Keller uses an inexpensive zeolite catalyst to transform ethanol into hydrocarbon blend-stock. The resulting liquid can be blended at various concentrations into gasoline, diesel, and jet fuels without negatively affecting engine performance. After mixing with petroleum-derived fuels, the blend-stock does not require modifications to the existing distribution infrastructure. [Read more…]

‘Do the math’ about fossil fuels, global warming, activist says

Bill McKibben

Since April 21, environmental activist Bill McKibben’s “Do the Math” movie has been shown around the nation and world. Its message is that catastrophic climate change looms large this century if fossil fuel use is not restricted.

In Oak Ridge, the movie has been shown several times at First Presbyterian Church, which is sponsoring McKibben’s lecture on Sunday, Aug. 18, at 7 p.m. at the Oak Ridge High School Performing Arts Center. The movie can be downloaded from McKibben’s grassroots organization www.350.org.

The author of two classics of environmental literature, “The End of Nature,” and “Eaarth: Making a Life on a Tough New Planet,” McKibben had the movie made after 350.org’s successful “Do the Math” tour of cities last fall. “Global Warming’s Terrifying New Math,” McKibben’s article a year ago in Rolling Stone magazine, inspired the tour.
