However, the main substitutes to oil face their own decline rates.

Many believe that the crisis can be prevented through conservation, technology, smart growth, recycling, electric cars and hybrids, substitution, or voting.

Many economists believe that the free market will substitute one energy source with another through technological innovation.

We've got a lot of work to do.

Now there's no question about it at all we will only solve the problem of replacing fossil fuels with technology.

He told us that Brazil's government mandated that every gasoline station in the country would carry ethanol.

They went out into the field to answer a particular question.

They are also limited to sunny climates, requiring large amounts of electricity to be transmitted over long distances.

like fishermen and ships and such things, but hey, we're talking about biofuels, and we know the importance of potentially getting an alternative liquid fuel.

I mean global warming certainly is a massive threat to mankind and we are putting a lot of time and energy into,

Let's say we converted all the vehicles in the United States to battery electric vehicles, hydrogen fuel cell vehicles or flex fuel vehicles run on E85.

This car runs on alcohol.

And so we thought perhaps there might be a better way to come up with an alternative cooking fuel.

Well, the fuel consumption is proportional to the drag force.

The car consumes a lot of fuel.

I need fuel.

Primary fuel?

Fuel supply?

Our fuel.

They now have 29,000 ethanol pumps this versus 700 in the U.S., and a paltry two in California and in three years their new car fleet has gone from four percent to 85 percent flex fuel.

Mine fuel

Primary fuel 2893 KRG.

What is he saying about the fuel?

Fuel cells.

The result is planes are 300 times

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

So, the idea is that if we fly around the world in a solar powered airplane, using absolutely no fuel, nobody ever could say in the future that it's impossible to do it for cars, for heating systems, for computers, and so on and so on.

The source of fuel crude oil.

Jet fuel.

The car ran out of gas before reaching the city.

Fuel economy is a big advantage of this car.

It's as if you have two fuel gauges on your car.

Rp7 rocket fuel burns at 5.000 degrees.

Other renewables only generate 2.5 .

General Electric natural gas turbine, you'll get about 60 percent efficiency.

Fuel, Skripach, fuel...

It's chemically fueled.

Fuelinjected.
