20 years ago, who is going to lobby for electrical cars or solar power? They aren't financially profitable.

We already are. At the national level, there is a High Speed Rail lobby group http://www.ushsr.com/

At the local level, it is up to you. In my city of Pittsburgh, we are removing parking and expanding transit access and bike lane coverage. But there is still a lot to be done, so I am advocating for change by participating in groups and contacting my city councilman.
