Gameday Recycling Tops ACC for Waste Minimization

Georgia Tech is a consistent leader in campus environmentalism, most recently ranking first in the Atlantic Coast Conference for Waste Minimization in the 2013 Game Day Challenge.

Harvesting Electricity: Triboelectric Generators Capture Wasted Power

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work.

PACE Awards Name Tech State Employer of the Year

Georgia Tech Parking and Transportation Services was honored this week with a PACE Award, winning the Government Champions/State Employer category for its efforts toward creating sustainable and alternative transportation options for campus.

As many on campus know, Georgia Tech offers a variety of commute options and incentives, including a bus and trolley system around campus, connectivity to the Midtown MARTA station, discounted or free Zipcar and carpool matching systems, and a pre-tax payroll deduction option for monthly MARTA passes.   

School of Architecture to use funding from Alcoa Foundation, gift from Resource Furniture to investigate Net Zero Energy housing in studio.

Students in Georgia Tech’s School of Architecture will be researching zero energy housing concepts in studio over the next year thanks to $133,000 worth of funding sponsored by Alcoa Foundation and Architecture for Humanity and a $25,000 contribution from NY-based furniture solutions company Resource Furniture.

School of City and Regional Planning chair appointed to United Nations expert group on urban planning

Bruce Stiftel, chair of the School of City and Regional Planning, was recently appointed to a United Nations (U.N.) expert group set up to advise U.N.-Habitat on the content of new international guidelines for urban and territorial planning intended for adoption by UN member states at the Habitat III gathering in 2016. 

Building the Future Power Grid: Researchers Tackle Energy Challenges with Technology Development and Policy Analysis

On a warm afternoon in August 2003, a high-voltage power line in a rural area of Ohio brushed against some untrimmed trees, tripping a relay that turned off the power it was carrying.  As system operators tried to understand what was happening, three other lines sagged into trees and were also shut down, forcing other power lines to shoulder the extra burden until they also tripped off, starting a cascade of failures throughout southeastern Canada and eight northeaster U.S. states.

Carbon-Neutral Energy Solutions Lab Unlocks the Potential of Clean Energy

In the past two years, the price of solar panels has dropped about 80 percent. Yet electricity from solar panels is still too expensive to compete with power from fossil fuels because the cost of all the other components and activities involved in installation— hardware, labor, permitting and inspection — hasn’t seen a comparable decline. This problem is among those being addressed at the recently-opened Carbon-Neutral Energy Solutions (CNES) Laboratory at the Georgia Institute of Technology.

Campus Encouraged to Take Two-Wheeled Transport during Bike Week

For the third time in as many years, Georgia Tech Bike Week is rolling through campus with events and competitions designed to encourage more people to bike on and around campus.

Design 2014 Earth Day T-Shirt, Win $500

At the 2014 Earth Day celebration, hundreds of people will receive T-shirts that they'll wear on campus for years to come — and they could be sporting your design.

The Earth Day planning committee is holding a design contest for this year's T-shirt around the theme "Green is Global." The winning designer will earn $500. 

Diesel or Electric? Study Offers Advice for Owners of Urban Delivery Truck Fleets

For owners of delivery truck fleets who may be trying to decide between electric or diesel vehicles, researchers at the Georgia Institute of Technology are offering some advice: comparisons of the energy consumption, greenhouse gas emissions and total cost of ownership for the medium-duty vehicles.

The advantages of electric versus diesel depend largely on how the trucks will be used – the frequency of stops and average speeds – and the source of electricity for charging batteries. In city driving with frequent stops, the electric trucks clearly outperform diesel vehicles.
