Where are the electric cars?

As we pollute the environment what has happened to all the research about electric cars? Have all the patents been gobbled up by corporations interested in making more money on polluting oil and gas as well as forcing higher costs and taxes on the consumer?

Also, why are there no solar panels on aircraft? These can be added to the fusilage without affecting areodynamics much and would provide extra energy to power the craft when in flight during the day and during take off / landing under clear skies.
