Schwarzenegger touts green technology -- on Twitter

California Gov. Arnold Schwarzenegger (R) showed off his green thumb on Twitter Thursday.

Arnold's official account tweeted a picture of him inspecting a hydrogen-powered locomotive: - Here I am inspecting BNSF's new Hydrogen locomotive. Very powerful and very clean!

The timing of the tweet could not be more apt; President Barack Obama touted clean energy jobs as part of his State of the Union address Wednesday night.

To give Schwarzenegger credit, he has long pushed green initiatives in California.
