Although it was far from his focal point, President Bush did touch on "clean energy" in his last State of the Union address Monday evening.

He called for the pioneering efforts of the cleantech industry to help the country curb its dependence on oil and in turn boost its energy security, pointing to technologies like nuclear power, batteries and renewable fuels.

And then he moved on to the one real piece of greentech news.

"Let us create a new international clean-technology fund, which will help developing nations like India and China make greater use of clean energy sources," he said.

It sound good, but from details on the White House's Web site, it amounts to $2 billion spread out over three years. That's not huge, considering the U.S. government has committed nearly $18 billion to the research, development and adoption of clean technologies during Bush's presidency, according to the same site.

Here's a visual aid to help put the announcement in perspective of some of the other commitments governments and companies have made to combat climate change (scroll down):

Countries and companies back cleantech in the billions. But the city of Abu Dhabi shows a certain fortitude in how much it's willing to support the sector.
