The source of fuel crude oil.

This is called energy density.

This stove burns oil.

This stove uses kerosene.

Petrol is no longer a cheap fuel.

This heating system burns oil.

The white lines are what's called an advance fuel cycle, where you reprocess.

Petroleum was replacing coal as fuel.

Every time you do so, some of the energy contained in the original fuel is lost.

I need fuel.

Primary fuel?

Fuel supply?

Our fuel.

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

Mine fuel

Primary fuel 2893 KRG.

What is he saying about the fuel?

Fuel cells.

When this happens, they're compressed under tons of pressure, and turned into carbon based fossil fuels

And then it makes natural gas, which then goes back into the city to power the fuel for the cooking for the city.

The global economy currently depends on endless growth, demanding an increasing supply of cheap energy.

Jet fuel.

Long lived nuclear waste that has to be kept out of the biosphere for over a quarter of a million years.

I spent it of food and eatables.

The thread that links them all our addiction to carbon based fuels,

Rp7 rocket fuel burns at 5.000 degrees.

Fuel, Skripach, fuel...

It's chemically fueled.

Fuelinjected.

But I'm not really concerned about the fuel.

In this kind of reactor, you can't do that.

Fossil fuels are needed for farming equipment, transportation, refrigeration, packaging in plastic, and cooking.

We've talked about the soil erosion.

As the pressure grew, so did the heat, until a chemical reaction transformed the organics into hydrocarbon fossil fuels

I made a promise that the next time I would fly around the world, it would be with no fuel, independent from fossil energies, in order to be safe, not to be threatened by the fuel gauge.

I can't give you a fuel injection.

Drop the fuel tanks and pull up!

Fill her up.

Like those cars that run on corn.

We're losing fuel.

We have a fuel leak!

It's like Michigan... hardcore propellant.

I was, you can see there, pulling two sledges.

If you wanted to read in 1875 at night, you needed to have an oil or a gas lamp.

Due to the shortages of such basic commodities as fuel, food and drinking water.
