Nissan Motor (NASDAQOTH:NSANY) is considering boosting production of the all-electric Leaf sedan after cutting prices earlier this year to more deftly reach a mass audience. Now General Motors' (NYSE:GM) Cadillac arm is releasing a high-end ELR EV to rival Tesla Motors (NASDAQ:TSLA). At the end of the day, more EV's mean more choices for consumers, and that's a good thing for a sector badly in need of competition and infrastructure. It's the latter I believe holds much portfolio promise and has me interested in the rebranding of NRG Energy's (NYSE:NRG) eVgo subsidiary which is developing further access to EV charging infrastructure. Other names investors may want to consider are PPL Electric (NYSE: PPL), a company with a relationship with GM on research, Duke Energy (NYSE:DUK), which is working on wireless charging technology, and DTE Energy (NYSE: DTE), which is exploring ways EV's will affect the grid.
