For four key technologies -- wind, PV, LEDs and batteries for electric vehicles -- in
each case there will be essentially a cost metric and it goes down, and there's a deployment
metric and it goes up very, very fast.
The most capacity deployed last year was wind. Solar -- a similar kind of story. LEDs, the
story is tremendous cost reduction with $100 lifetime savings for one bulb. The fact is
we made 100,000 electric vehicle sales this year. We really are developing some of the
zero-carbon technologies that are going to be part of the future.
