Battery prices need to come down even further, but electric vehicle (EV) growth is encouraging. I still see some geographical risks associated to weather that could impact EV range performance, but new technologies are starting to lessen those fears. Tesla (TSLA 4.96%) has done an amazing job in the past year of exceeding forecasts and creating market awareness. However, more than ever management needs focus and execution to justify the stock's valuation amid increased competition. 

The Toyota (TM -3.23%) Prius recently saw a price reduction, and that may very well spill over to General Motors' (GM 1.20%) hybrid Chevy Volt. At the end of the day, I'm more encouraged by hybrids over the pure EV but do believe a mix of autos is really in consumers' best interests.
