Many of us living in Massachusetts travel for recreation: skiing in New Hampshire, a summer’s weekend down at the Cape, a camping trip in Amherst woods or even the two-hundred-mile trip from Boston to New York City. For drivers of electric vehicles, these trips averaging eighty to a hundred miles can be daunting.
Most electric vehicles are limited by the charge in their batteries and can only go sixty to a hundred miles on a single charge, depending on traffic and driving habits. Standard battery charging times of six to eight hours don’t cut it. For these long trips, drivers need powerful charging stations that can recharge a car’s battery quickly, ideally within the time of a lunch break or even a bathroom break.
EEA Secretary Rick Sullivan, UMass Amherst Chancellor Kumble Subbaswamy and other campus officials in early February marked the installation of the first public level three electric vehicle charger in Massachusetts at UMass Amherst. Level three chargers, also known as DC fast chargers, operate at 480 volts and can charge electric cars much faster than most existing chargers – up to an 80% charge in less than thirty minutes for a Nissan Leaf. Most of the currently available electric charging stations that you might see at parking lots are level two chargers that operate at 240 volts and take nearly a full work day to fully charge a car. There aren’t many DC fast chargers on the road; these are much more expensive to purchase and install than the regular level two 240-volt chargers.
To help with the installation costs, the Department of Energy Resources (DOER) obtained a grant for installing public DC fast chargers. The Congestion Mitigation and Air Quality (CMAQ) Improvement Program sponsored by the U.S. Department of Transportation’s Federal Highway Administration provides funding for transportation projects aimed at providing clean air and reducing traffic. With more public DC fast chargers available, electric vehicle drivers can drive further and use their electric vehicles for long road-trips, reducing emissions. DOER’s Clean Cities Coalition program plans to fund more level three chargers, extending the range of more electric vehicles in Massachusetts.
The Amherst DC fast charger was obtained through a partnership with Nissan USA. Drivers with a membership to Chargepoint, a national system of charging stations for electric vehicles, will be able to access the Amherst DC fast charger for about $3 a charge, according to Bill Watts of Transportation Services at UMass Amherst. Currently, Nissan Leafs (Leaves?) and the Mitsubishi i-Miev are the only electric vehicles in the U.S. that can use the type of fast charger installed at UMass, but other electric vehicle models are expected to join the Leafs and i-Mievs in fast charging within the next year with the use of an adapter.

Comparing Homes – Energy-Saving Enters the Equation posted on Aug 28
Until recently, there was no way to easily figure energy efficiency into a home buying decision. Enter HomeMPG, a Massachusetts energy-saving initiative to pilot an energy performance score (EPS) in residential homes. This “asset” rating that’s analogous to a car’s MPG rating. Behavior is taken out of the equation so that any home’s energy use can be compared to any other home, allowing for an apples-to-apples comparison.
Massachusetts Milestone: 15,000 Solar Installations posted on Aug 25
Massachusetts has just surpassed an exciting milestone of 15,000 solar photovoltaic (PV) installations, proving that solar energy has become a smart, popular choice here. In fact, as of August 21, there were 15,762 systems installed across Massachusetts, a twenty-fold increase from 2007 when Governor Deval …Continue Reading Massachusetts Milestone: 15,000 Solar Installations
