Cleantechnica has heartening news from the Bloomberg New Energy Finance report.  Battery prices for electric vehicles, a key factor thus far in keeping electric cars more expensive to buy than smoggier alternatives, are dropping, and somewhat quickly. “According to an April 2012 Bloomberg New Energy Finance report, the average price of batteries used in electric vehicles dropped 14% from Q1 2011 to Q1 2012. ‘The average price of an EV battery at the end of Q1 2012 was $689 per kilowatt hour, compared to $800 per kilowatt hour in 2011, according to that report. “Compared to 2009, prices were down approximately 30%. “By 2030, BNEF projects battery prices will fall to $150/kWh (in 2012 dollars).” The report explains, “Electric vehicles such as the Mitsubishi Motor …
