There's something kind of thrilling about hearing a staid, major, heavy-hitting think tank executive with a massive budget go visionary on what it'll take to beat this whole climate change situation into shape:

"Here is what we know.  First, we know that we need a low-carbon economy by mid-century.   Second, we know that it will take a new industrial revolution to get there, and that low-carbon energy technologies will play a critical role in that revolution.  And, third, we know that all signs indicate that we cannot and will not achieve a low-carbon economy if we continue on a “business-as-usual” path. ...

"I believe we need to be thinking about four major issues as we map our path to a low-carbon future.  The first of these is technology development—in other words, how to spark an energy technology revolution."
