But that potential pales beside the never-ending demand for crop-based fuels.

A fourth of this year's U.S. grain harvest will go to fuel cars.

As part of its 30 Ways in 30 Days program, It's asking communities across the country to help the more than 200 food banks and 61,000 agencies in its network provide low-income individuals and families with the fuel they need to survive.

Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments.

Already there are many alternative fuel vehicles on the market, powered by anything from solar power to natural gas.

But as we all know, of all these alternative fuel vehicles, the most practical are electric vehicles

Solutions to global fuel shortage.

He has got to save on fuel bills

The fuel price has skyrocketed.

Bringing back unneeded equipment would have used up precious resources such as fuel.

During 26 vigorous exercise, our muscles tire as they run out of fuel and build up waste products.

The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to survive on smaller budgets.

The extensive data sources, combined with computer simulations, created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel emissions.

Unfortunately, the current low prices for oil, gas, and coal may provide little incentive for research to find even cheaper substitutes for those fuels.

There is strong evidence that both innovation and adoption of cleaner technology are strongly encouraged by higher fossil fuel prices.

The same is true for new technologies for alleviating fossil fuel emissions.

The current low fossil fuel price environment will thus certainly delay the energy transition from fossil fuel to clean energy sources.

The International Monetary Fund calculates that countries can generate substantial fiscal revenues by eliminating fossil fuel subsidies and levying carbon charges that capture the domestic damage caused by emissions.

Renewables account for only a small share of global primary energy consumption, which is still dominated by fossil fuels—30% each for coal and oil, 25% for natural gas.

Progress in the development of renewables could be fragile, however, if fossil fuel prices remain low for long.

Notwithstanding important recent progress in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in, and adoption of, cleaner energy technologies.

Natural gas and coal—also fossil fuels—have similarly seen price declines that look to be long-lived.

It is urgent for governments to increase the cost of using fossil fuels to an appropriate level to lessen the catastrophic effects of climate change.

If not corrected by the appropriate carbon price, low fossil fuel prices are not accurately signaling to markets the true social profitability of clean energy.

Higher fossil fuel prices prove to be conducive to innovation and application of cleaner technologyIf fossil fuel prices remain low for a long time, it may lead to higher emissions of greenhouse gases.

Fossil fuels remain the major source of primary energy consumption in today's world.

Fossil fuel prices are likely to stay low for long.

Even major fossil fuel exporting countries have great potential to develop renewable energies.

Even Africa and the Middle East, home to economies that are heavily dependent on fossil fuel exports, have enormous potential to develop renewables.

Direct subsidies to research and development have been adopted by some governments but are a poor substitute for a carbon price: they do only part of the job, leaving in place market incentives to over-use fossil fuels and thereby add to the stock of atmospheric greenhouse gases without regard to the collateral costs.

But renewable energy will have to displace fossil fuels to a much greater extent in the future to avoid unacceptable climate risks.

Today's battery breakthroughs come as the world looks to expand modern energy access to the billion or so people without it, while also cutting back on fuels that warm the planet.

They fueled a lot of controversy.

In other words, a few countries are benefiting enormously from the consumption of fossil fuels, while at the same time contributing disproportionately to the global burden of climate change.

His attitude to state intervention has looked confused ever since his bizarre 2006 lament that chocolate oranges placed seductively at supermarket checkouts fueled obesity.

The major components of our energy systems, such as fuel production, refining, electrical generation and distribution, are costly installation that have lengthy life spans.

Viewed from scientists’ standpoint, allthe energy contained in fuel either now or in the future becomes heat.

Providing powerful hand-held devices is sure to fuel debates over the role of technology in higher education.

Even Africa and the middle East, home to economies that are heavily dependent on fossil fuel exports, have enormous potential to develop renewables.

In the past 12 months, Nigeria has suffered from a shrinking economy, a sliding currency, and a prolonged fuel shortage.

Many European countries have been making the shift to electric vehicles and Germany has just stated that they plan to ban the sale of vehicles using gasoline and diesel as fuel by 2030.

They also, however, use far more natural resources—fuel, water all those baths and golf courses and building materials.

They are used to fuel cement ovens.

with the proceeds pooled, can help to extend opportunities and fuel community spirit.

Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean's appearance.

It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.

Research suggests warm colors fuel our appetites.

The efforts to fuel the growth of phytoplankton.

Here was abundant fuel and lumber.

It takes more upkeep, burns more fuel and is slow off the starting line because it depends on learning—a gradual process—instead of instinct.

There are reports that some military aircraft flew in formation when they were low on fuel during the Second World War, but Dr. lissaman says they are unsubstantiated.

They found that the aircraft consumed as much as 15% less fuel.

You'd think this might fuel the efficiency mind-set, but in fact, Eberle notes, such ritualistic behavior helps us "step outside time's flow" into "soul time".
