Well, let's talk about climate change.
Now, people think,
"Hey, aren't we getting the solar panels and windmills
to be a lot less expensive?
And isn't that helping reduce greenhouse gases?”
And the answer is, absolutely.
But, there's a lot more to do
than just taking electricity to zero emissions.
There's a variety of things
that generate greenhouse gases.
We have a lot of sectors of the economy,
like manufacturing, that are emitting greenhouse gases
that aren't talked about as much.
Manufacturing.
Everything we make even a cute little squishy like this,
that's emitting 21% of the greenhouse gases.
The number of buildings in the world
is going to double by 2060.
It’s like we're going to build a new New York City
every month for the next 40 years.
It’s a gigantic amount of materials.
Steel, cement, wood, all emitting greenhouse gases.
We’re going to have to figure out
how to make all these things in a different way.
And so, we’re going to need a lot of change,
a lot of innovation,
to bring the emissions
from all those areas down to zero.
