This is from real data in California,

Let's go more nuclear,

I don't think so. I don't think even close.

So and then when you compare the lifetime emissions of these various energy forms, nuclear is about even with solar and wind, and ahead of solar oh, I'm sorry with hydro and wind, and ahead of solar.

So the other thing is, we don't need nuclear energy.

And that changes everything.

Wind takes about two to five years on average, same as concentrated solar and photovoltaics.

So my premise here is that nuclear energy puts out more carbon dioxide, puts out more air pollutants, enhances mortality more and takes longer to put up than real renewable energy systems, namely wind, solar, geothermal power, hydro tidal wave power.

Saul Griffith did the numbers and figured out what would it take to get 13 clean terawatts of energy from wind, solar and biofuels, and that area would be roughly the size of the United States, an area he refers to as Renewistan.

I would love to have something in the fourth place here, but in terms of constant, clean, scalable energy, solar and wind and the other renewables aren't there yet because they're inconstant.

Solar Winds

So we've analyzed the hour by hour power demand and supply,

Richard Heinberg kindly agreed to talk to me via the internet.

pennsylvania's exercising leadership on solar power and wind power.

Setup Solar Wind

The sun sends out light.

She dreamt of blue skies, soft breeze and sunshine.

I love being around these big wind generators.

Yeah. I believe we don't really appreciate what we have, and I only speak for myself.

So in the environment that we grew up in, the light comes from the sun and the sun is above.

(Laughter)

Did you see the glare?

MICHAEL We're losing the light!

The sun gives light and heat.

I've got data to back up all these assertions, by the way.

This makes a Hydrogen economy unlikely.

We can do the same for geothermal energy and solar power.

That is a named consequence of geoengineering.

When sunshine leaves.

This has to be a bridge to the point where you can get to wind, to the point where you can get to solar, to the point where you can get to nuclear and hopefully you won't build the next nuclear plant on a beautiful seashore next to an earthquake fault.

But better what is more important is that they would have to concentrate sunlight.

So when you add up the greenhouse gases in the lifetime of these various energy sources, nuclear is down there with wind and hydro, below solar and way below, obviously, all the fossil fuels.

We're often told though that only coal and nuclear plants can keep the lights on, because they're 24 7, whereas wind and solar power are variable, and hence supposedly unreliable.

Miami, Florida.

I love renewables. But I'm also pro arithmetic. (Laughter)

When sunshine returns.

Sunny as in the sun and sunshine.

It's probably good assumption, that the halo of the milky way doesn't rotate very much and sun goes around the galactic center.

If you go to nuclear, you do get a big reduction, but it's not as much as with wind and concentrated solar.

Most people choose to lease.

All you can see is a little bit of erosion down here.

So all the light in this area from the sun and the moon is what you see on the screen right here.

In fact, every region of the country could do this.

As of 2007, there are only about 4 square miles.

In the summer when the Sun is higher in the sky, the rays from the Sun are dissipated by less atmosphere.
