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

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.

CA But natural gas is a fossil fuel.

But all of these advances rely on abundant fossil fuel.

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

A lot of environmentalists who are always trying to drive us towards using less energy, because all that energy's coming from the consumption of fossil fuel.

Small cars are very economical because of their low fuel consumption.

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

As long as industrial nations consume energy and developing countries increase their fossil fuel consumption, the concentration of greenhouse gases in the atmosphere will continue to rise

So, let's compare the fuel consumption of a plane with a car.

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

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.

If you just plot how much fuel we've got left, in units of present world consumption.

Fuel, Skripach, fuel...

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.

We're actually measuring its oxygen consumption, its energy consumption.

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.

language was fossil metaphor.

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.

And clearly, with what's going on with fossil fuel usage, or when as the fossil fuel is going away, as oil hits its peak oil, you know, we really have to start thinking about whether or not we should, or could, be moving food 1,500 miles before we eat it.

But instead of placing a rising fee on carbon emissions to make fossil fuels pay their true cost to society, our governments are forcing the public to subsidize fossil fuels by 400 to 500 billion dollars per year worldwide, thus encouraging extraction of every fossil fuel mountaintop removal,

Mine fuel

linear by cyclical fossil fuel energy by renewable energy, sunlight wasteful by waste free and abusive by benign and labor productivity by resource productivity.

So, up here in the mountains, there's no need for sacks of fossil fuel derived nutrients, it's all done by nature nitrate, potash, phosphate.

Power Consumption self powered

I want pure consumption.
