Rep. Edward Markey ends this hearing by suggesting that oil companies spend 10 percent of their profits on renewable energy research. Not sure, no time to watch all 2+ hours right now, but this might be the April hearing where I heard the oil execs all state they were planning for oil to be the dominant source of U.S. energy until my kids are almost my age.

Michael Raupach told listeners at a climate change conference yesterday that Australia could go solar by 2030.

Maybe it's -- not all, but partly -- a matter of wanting to.

Me? I don't really think banking on the oil companies to fund any extensive purposeful research that runs counter to their immediate business interests is a realistic expectation.
