Coal is a fossil fuel.

Powered by fossil fuel derived energy.

Modern cities are fossil fuel dependent.

Modern cities are fossil fuel dependent.

Fossil fuel prices shot through the roof.

Let's look first at the burning fossil fuels, either burning coal or burning natural gas.

CA But natural gas is a fossil fuel.

Of the fire (kept burning) with fuel,

CA Most of American electricity comes from burning fossil fuels.

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.

We have the reckless burning of fossil fuels along with other greenhouse gasses, so called,

There is no burning of the fuel in the centre of the planet.

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

And you can see that it's a lot cleaner burning of a cooking fuel.

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.

Your car won't go forever unless the engine keeps burning fuel to drive and consuming energy

Fuel, Skripach, fuel...

And all the burning of oil and coal and gas, all the fossil fuels, have changed the atmosphere greatly.

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.

And what's more, this guy doesn't need a wire connected all the way back to a power station burning fossil fuels.

The biggest single cause of global warming, along with deforestation, which is 20 percent of it, is the burning of fossil fuels.

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.

If the dark energy remains around, the stars around us will use up their nuclear fuel, they will stop burning.

language was fossil metaphor.

This shows that the effect of the Sun's variations on climate is overwhelmed by the increasing greenhouse gasses, mainly from burning fossil fuels.

Well, in the long term, it's absolutely certain that present methods can't because they're so entirely dependant on energy, on fossil fuel energy.

Following the invention of fossil fuel derived fertilisers and pesticides there were massive improvements in food production, allowing for increases in human population.

Throughout this journey, we have also discovered our passion for science, and are currently continuing research on other fossil fuel chemicals in university.
