Geometry was the first exciting course I remember.

Switching to light-coloured roofs and roadways would have the equivalent effect on greenhouse gas emissions to taking one billion cars off the road for eleven years.

What the American family does not want is to pay an increasing fraction of their budget, their precious dollars, for energy costs.

As the saying goes, the Stone Age did not end because we ran out of stones; we transitioned to better solutions. The same opportunity lies before us with energy efficiency and clean energy.

I think the Caribbean countries face rising oceans and they face increase in the severity of hurricanes. This is something that is very, very scary to all of us. The island states in the world represent - I remember this number - one-half of 1 percent of the carbon emissions in the world. And they will - some of them will disappear.

A cap and trade bill will likely increase the costs of electricity. . . . These costs will be passed on to the consumers.

We should look at considering duties that would offset that cost.
