Powered by fossil fuel derived energy.

That beam emits high energy microwaves

Blame high fuel costs, blame insurance premiums, blame technology.

Nano engineered fuel cells could provide the energy where it's needed.

So much more energy can be stored with fuel than with batteries.

Fuel, Skripach, fuel...

Thanks to High Commander Anna's gift of Blue Energy...

The fuel shortage awoke the country to the need for developing atomic energy.

less than one percent of the fuel energy ends up moving the driver.

Here, quite a high rate, 23 of the total energy is generated by natural energy.

How much energy did the neutron have that you smack the nuclear fuel with?

Thermodynamics typically gives us about 30 percent of the energy when we burn fuel.

They couldn't use high pressure reactors. They couldn't use complicated solid fuel reactors.

If you use more energy to get the fuel than is contained in the fuel, it's not worth the effort to get it.

Fuel the Jet, Fuel the Jet.

After all, the energy content of antimatter is a billion times higher than conventional fuel.

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.

It needs help from the high energy rays of the sun.

The teacher was running around, and the energy level was high.

But they're also materials with very high energy and very high greenhouse gas emissions in their process.

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.

It's the same energy question that you're looking at today, but it's different sources of fuel.

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

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

I don't mention the high energy efficiency of these LED light bulbs.

It's the high energy state, or the transition state of the reaction.

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

Mine fuel

Primary fuel?

Fuel report.

Fuel supply?

Jet fuel.

Our fuel.

Fuel cells.

Fuel... power...

Our sweet tooth is an evolved and instinctual preference for high energy food.

So we embarked upon the reinvention around an electrochemical engine, the fuel cell, hydrogen as the energy carrier.

I need fuel.

No fuel injection?

I require fuel.

We're losing fuel.

How much fuel?

Fuel the jet.

Unconventional natural gas is controversial, as it needs high energy prices to be profitable.
