MALE SPEAKER: I'd like to welcome Phil Warburg back

to Google to talk about his book called "Harness the Sun".

He was here earlier to talk about "Harvest the Wind"

As you see he's very interested in alternative energy

and why it's the future of energy in the United States.

like the invited Phil up to talk to us about his new book.

PHILIP WARBURG: It's great to be back at Google

about technological transformation than Google.

I want to start by asking how many of you

OK, and I want to see those hands together.

So that really says something to me about solar power today.

And that is that it's really become part of our lives

whether we've invested in it individually

or whether we're part of a broader community that

has decided that solar is a worthwhile investment.

And by worthwhile I mean a number of things.

For some people, that is simply lowering their electric bills

now and thinking about future fuel prices and stability

going forward in terms of their electric bills.

For some, there's satisfaction in trimming

by generating at least part, or a substantial part of,

in taking charge of at least some of the power

is one that I found particularly intriguing

to different people about their own commitment

to be avid solar proponents-- he wrote a wonderful blurb

on the back of my book-- former Head of the Energy and Commerce

Sea solar as part of broader panoply of necessary

the overwhelming challenge of climate change.

for solar power among at least a contingent of very

People like former congressman Barry Goldwater Jr.,

for a number of years, he now is the chair

of something called TUSK-- Tell Utilities

And what that group does is it's a representation of homeowners

and business owners who want to generate solar

on their properties and who want fair compensation

for the surplus power that they generate and they are fighting

major utilities, such as Arizona Public Service, which

wants to cut back on the net metering benefits that

are provided to solar homeowners and solar business owners.

the gaping political chasm that exists in America today,

but at least it's a sign that there is a common language

that we can talk across the political spectrum

in looking at some of our renewable energy opportunities.

Back in 2012 when I was just wrapping up my book on wind

And my kind of flip and dismissive comment at the time

was that if I ever wrote a book about solar,

And the reason I said that was because at the time,

it just struck me that solar was pricing itself out

of the market and was not on the verge of becoming a mainstream

Thankfully, and fairly quickly, I was proven wrong.

of residential and utility-scale solar came down about 46%.

as in commercial and public building related solar,

So a very dramatic drop in a very short period of time.

And another powerful indicator of just where solar is today

can be found in the first half of this year's new generation

Solar, during the first half of this year,

accounted for 39% of all new power generation capacity

looking at 75% of our new electric generating capacity

in the first half of this year coming from renewable sources.

as the cheaper, more convenient, accessible options--
