Coal is a fossil fuel.

Powered by fossil fuel derived energy.

Modern cities are fossil fuel dependent.

Modern cities are fossil fuel dependent.

The world runs on fossil fuel.

Fuel... power...

Fossil fuel prices shot through the roof.

CA But natural gas is a fossil fuel.

But all of these advances rely on abundant fossil fuel.

And thirdly, changing from a fossil fuel economy to a solar economy.

Well, let's say your energy's not coming from the consumption of fossil fuel.

One is by drudgery and the other is by chucking fossil fuel at it.

The military power of this world depends on fuel.

Aside from transport, cars, trucks and airplanes, agriculture is the most fossil fuel intensive industry.

But for my part, weaning this farm off fossil fuel is all I can do.

One unit like this is an energy unit of fossil fuel oil, coal or gas.

About 7 calories of fossil fuel energy are used to produce 1 calorie of food.

Besides fossil fuel decline, there are several threats to the current system of food production

Fossil fuel usage is down 60 percent per unit of production, due to efficiencies in renewables.

All the farms I know, including organic ones, are utterly dependent on fossil fuel, particularly oil.

Nitrogen run off by fossil fuel based fertilisers poisons rivers and seas, creating enormous dead zones.

As most power is generated from fossil fuels, this is not a solution.

Fuel, Skripach, fuel...

It's for power generation, transportation, it's peaking fuel, it's all those.

There are other options for generating power as well, which don't involve fossil fuels.

Fossil record study?

I don't think most people have given it much thought how much fossil fuel goes into our everyday food.

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

If we started today, 10 years from now, at the end of this window of opportunity, those fuel efficient cars will reduce our fossil fuel needs by four percent.

We use in the industrial world about ten calories of fossil fuel energy for every calorie of food we produce.

Which is an amazing fossil fuel savings, if we were to just put that on the edge of a wing.

Fuel the Jet, Fuel the Jet.

language was fossil metaphor.

Mine fuel

Primary fuel?

Fuel report.

Fuel supply?

Jet fuel.

Our fuel.

Fuel cells.

Even the latest technologies, like GM crops, regardless of the other arguments, are as utterly dependent on fossil fuel as any other.

The only reason modern agriculture can get away with killing the life in the soil is through another use of fossil fuel.

So in a sense this is an absolute zero carbon, zero fossil fuel electric mile at two cents a mile by 2020.

He is a living fossil!

To replace the 10 terawatts the world currently generates from fossil fuels, would require 10,000 nuclear power plants.
