Life was very small for most people.

Production was centralized in assembly plants.

Now, I want you to just look really close up onto what's happened there.

So, no surprise, there's lots and lots of waste. What you want to do is improve productivity with which we use energy.

So what I'm telling you about is a system of integrated activities.

Education six, seven, eight percent of the economy and growing.

A global crisis in agriculture.

It will stop because of the end of trade resources.

And so that the cost of goods is literally how much did it cost to buy the metal and the paint and provide the electricity to make those 3 million worth of widgets.

Then hear this, please.

And China does play a big role in it.

Well, our heat was was not adding kinetic energy to the system.

So this is when we're at this thing right here.

This is 200 years of history, and for 200 years we've been systematically decarbonizing our energy system.

So the idea that we can smoothly transition to a highly efficient, solar powered, knowledge based economy transformed by science and technology so that nine billion people can live in 2050 a life of abundance and digital downloads is a delusion.

We'd have a water treatment system treating wastewater, turning that into fresh water and generating energy from the solids using just plants and micro organisms.

lighting can be changed without destroying the sense of realism. Rather than

Unlike an aircraft carrier or an atomic bomb, you don't need a massive manufacturing system to build robotics.

And it's important to note that it's not just the stars who are benefiting because you can see the best, everyone can learn.

I learnt many things here.

Mass production?

Portugal was 45 percent renewable powered,

We're really excited to be partnering with Duke

Now, in order to do this, we need the right kind of language.

All right.

Gross National Product is not the same as Net National Product.

For every calorie of food that we consume here in Britain today, 10 calories are taken to produce it.

And now comes the so called Renewable energy evolution.

So, what we call this is a silicon cottage industry.

GDP says look, if it was produced inside the country, we don't care who it's been produced by.

Alex Hi, I'm Alex. I just wanted to say,

In Europe, France that heavily depends on nuclear power generation,

And then on the horizontal axis quantity, produced.

Why didn't they put it into production?

So countries like Australia, Russia, Libya, Kazakhstan, could be our best friends for renewable production.

We should pursue more energy efficient lifestyles, absolutely. How far can we go, though?

which I find is somewhat ironic.

They laughed more than you guys are. (Laughter)

And, In the end, that actually leads to inflation.

So more people, eating more stuff, and richer stuff, and of course having an energy crisis at the same time, where we have to replace oil with other energy sources that will ultimately have to include some kinds of biofuels and bio energy sources.

linear by cyclical fossil fuel energy by renewable energy, sunlight wasteful by waste free and abusive by benign and labor productivity by resource productivity.

Renewable or recyclable materials are 25 percent of the total, and growing rapidly.

And this is an ongoing research. This is not rocket science.

Now let's say I can take this 20 thread and I'll stay with white I can take this 20 thread and I could throw in some more labor

25 percent just like 25 percent emissions today comes from cars 25 percent of their energy for the entire industrial world in the U.K. came from a source of energy that was immoral human slaves.
