Nissan Motor (NSANY -0.24%) 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' (GM +0.44%) Cadillac arm is releasing a high-end ELR EV to rival Tesla Motors (TSLA +0.68%). 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 (NRG +5.42%) eVgo subsidiary which is developing further access to EV charging infrastructure. Other names investors may want to consider are PPL Electric (PPL +0.95%), a company with a relationship with GM on research, Duke Energy (DUK +0.42%), which is working on wireless charging technology, and DTE Energy (DTE +0.94%), which is exploring ways EV's will affect the grid.
