Portugal was 45 percent renewable powered,

And now comes the so called Renewable energy evolution.

We're really excited to be partnering with Duke

I've got a hydro conversion at a watermill that I own.

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

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

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

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

We must develop renewable energy sources.

Remember where we are, 1.25 watts per square meter, wind farms 2.5, solar parks about five.

For each of the past four years half of the world's new generating capacity has been renewable, mainly lately in developing countries.

Rechargeable

So here's a summary so far

This was from Nature magazine.

We want to match the hour by hour power supply.

(Laughter)

They have flown in the past, but without saving capabilities, without batteries.

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

The beauty of hydrogen is it can come from so many different sources it can come from fossil fuels, it can come from any way that you can create electricity, including renewables.

Do you know, they only invested 0.2 percent of revenues in R amp D?

The last three of the five, I've grouped together.

We just flush all this water down the lavatory, it's terrible.

We can look at some of the data.

Traditionally utilities build a lot of giant coal and nuclear plants and a bunch of big gas plants and maybe a little bit of efficiency renewables.

But we want to make the energy use as small as possible.

Location of the playable item

Of course, other metrics matter, too, and nuclear power has all sorts of popularity problems.

And, ultimately, the arithmetic problem isn't going to go away.

They all have a small power per unit area, and we have to live with that fact.

If we take a look at electricity, currently, renewable energy only accounts for 3.2 of the total energy generation.

lags behind the sustainable energy development, while countries like Denmark that doesn't own a nuclear power plant are advanced in widespread use of renewable energy.

In 2010, renewables other than big hydro, particularly wind and solar cells, got 151 billion dollars of private investment, and they actually surpassed the total installed capacity of nuclear power in the world by adding 60 billion watts in that one year.

And it's how all of Europe can shift to renewable electricity.

Electric cars can be recharged at home.

There's a slight possibility of a recurrence.

The global economy grows exponentially, at about 3 a year, consuming increasing amounts of non renewable fuels, minerals and metals, as well as renewable resources

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.

The last person who was in favor made the premise that we don't have enough alternative renewable resources.

Ray Kurzweil and all the other talks we know that the stick is going up exponentially.

Well, I think out ahead of us a few decades is peak gas, and beyond that, peak renewables.

Hourly simulations show that largely or wholly renewable grids can deliver highly reliable power when they're forecasted, integrated and diversified by both type and location.

So let me run you through a few ideas.

Renewables is one of the leading ideas for how we could get off our 90 percent fossil fuel habit.

So just looking at this heart,

Because then renewables such as wind and solar come out from the wings, here to center stage.
