Can We Have Some EV Sanity?

December 7, 2013 by Lou Grinzo

Finally, at long last, there’s word that Nissan might give Leaf buyers an option about battery size. Instead of trying to guess which one battery size will make your EV product offering the most profitable, why not give the customer at least two options, as Tesla does?[read more]

August 30, 2013 by Tina Casey

GE Flow Battery

We were just fooling around with the notion that new fuel cell technology could shake up the electric vehicle market when GE creates an alternative: a flow battery combined with a fuel cell to push EV range up to the Department of Energy’s goal of 240 miles and more.[read more]

Energy storage can contribute to the smart grid by facilitating integration of renewable sources and provision of important ancillary services. At the same time, energy storage cannot really be exploited to its fullest potential without a smart grid infrastructure capable of managing bidirectional energy flows. Because of that reciprocal...[read more]

Do electric cars really save carbon emissions?

July 18, 2012 by David Thorpe

Smart grids, together with electric vehicles, will enable their owners to sell power back to the grid, make money for themselves, and help keep the network from overloading. But research shows that the cost of reducing carbon emissions this way is high compared to other methods. Smart grids will be essential to the mass public uptake...[read more]

Why Use Rooftop Solar Panels to Power Your Electric Vehicle?

June 28, 2012 by Chip Gaul

Solar cells stand to place an increasingly prominent role in augmenting the practicality of electric cars.  In theory, the idea of using solar panels to charge electric cars seems a perfect combination. The sun is the planet’s greatest source of free energy and anyone with the capacity to harness it is at an advantage. The reality...[read more]

How to Leverage Data to Increase Clean Tech Sales

In last month’s post “How to Grow Electric Vehicle Sales”, I discussed the importance of understanding your target customers so you can successfully market your new clean tech product or service. For instance, the people who brought the early Toyota Prius - typically middle aged, upper middle class, highly educated, environmentalists –...[read more]

It's the Battery Costs, Stupid!

May 9, 2011 by James Greenberger

The recent run up of gas prices certainly makes electric vehicles potentially more attractive to consumers. But counting on high gas prices alone to promote electrification is not a good bet. Consumers have many options to reduce gas expense—buying fuel-efficient four cylinder cars being an obvious and inexpensive one. To capture the automobile consumer and break the stranglehold of petroleum on the U.S. economy, the price of electric vehicles must be brought sharply down. And there is only one way to do that: By reducing the cost of the advanced batteries that power them.[read more]

National Strategy For Electric Vehicles Should Focus on Secondary Battery Use

October 24, 2010 by James Greenberger

The high cost of advanced batteries is the elephant in the PEV room. Focusing solely on battery research and manufacturing capacity isn’t a strategy; it is just hope. A sound strategy must focus on promoting secondary commercial markets for advanced automotive batteries.[read more]

Volvo and Mack Produce a Powerful Alternative

February 5, 2010 by Mike Smith

When you enter the Washington, DC convention center at this year’s RETECH show, continuing today, one is confronted by a nearly 28,000-ton truck of magnificent proportions. It is over 11feet high standing at the first booth in the hall.   The familiar Mack Truck Bulldog greets you upfront on the hood. The big, blue behemoth is an...[read more]

Killing the Electric Car Again — Part 1

March 13, 2008 by Joseph Romm

If you’ve seen the movie Who Killed the Electric Car? (which is ranked #8 at Netflix in documentary rentals), then you know the EV story up to 2003. What you might not know is that one of the players in the movie, the California Air Resources Board (CARB), looks like it is up to no good again. In killing Battery Electric Vehicles (BEVs)...[read more]
