Advanced inverters can continue to operate and even assist in smoothing out an increasingly variable grid

Advanced inverters, or smart inverters, are sophisticated versions of the devices long used to convert the direct current output of solar panels into the alternating current used by consumers across the electrical grid. Whereas traditional inverters are programmed to shut off during disturbances on the electrical grid, advanced inverters can continue to operate and even assist in smoothing out an …

One-way car-sharing saves money, GHG, and takes 7-11 vehicles off the road for each shared one

A recent study done by researchers at University of California-Berkeley has answered several questions many have had since car-sharing began: Does car sharing increase or decrease driving? What is the effect on overall VMT, vehicle ownership, and GHG emissions among car-sharing members? The researchers used data from car2go in five North American cities—Calgary, San Diego, Seattle, Vancouver, and Washington, D.C.—and …

New research on the cost-effectiveness of additional bicycle infrastructure

A recently published study sheds new light on the importance of the built environment in influencing bicycle commuting and the resulting impacts on greenhouse gas emissions.  The researchers first gathered household travel survey data for the years 1998, 2003, and 2008 for residents of Montreal. They then generated neighborhood typologies, dividing the city of Montreal into a 500-meter grid and …
