The initial design failed to meet the Boeing required specific fuel consumption (SFC).

JF Over on the left hand side, you will notice fuel consumption decreasing as the rocket takes off.

Indeed, the government indicates that it may begin rationing gasoline.

This resulted in reduced fuel consumption and less environmental impact.

But the rampant consumption of sugar that marks this time of year is nothing to celebrate.

For example, now is the time to begin reducing US oil demand through improved fuel economy standards and or progressive increases in fuel taxes.

One country is supporting the introduction of techniques to alleviate the consumption of wood for heating and construction.

Together the improvements provided a 1.2 improvement to the Trent 700's specific fuel consumption.

A carbon tax has also been proposed as a method to reduce consumption of fossil fuels.

The atmosphere is filling with greenhouse gases from heavy use of fossil fuels.

The challenge is to enable freedom of mobility while reducing the consumption of fossil fuels.

In these Parties, changing consumer behaviour was envisaged as a way to reduce fuel consumption from transport and reduce emissions.

They buy more fuel efficient cars and appliances, insulate their homes, and sometimes even use public transportation.

Countries like his own were the victims of the world's short sighted drive to burn more and more fossil fuels.

Diversity in modes of transportation Sustainable transportation emphasizes the use of a diversity of fuel efficient transportation vehicles in order to reduce greenhouse emissions and diversity fuel demand.

The US will not solve its energy security problem until it gets better at fuel economy, possibly by a combination of technology, gasoline taxes, and regulations.

Resources and consumables the possibility of monitoring resources using electricity, water and fuel oil consumption is being considered as an aid to verification.

For example, while Americans could have supported more aggressive fuel economy standards or increased federal taxes on energy, they didn t.

2007 Gasoline Rationing Plan in Iran was launched by president Mahmoud Ahmadinejad's cabinet to reduce that country's fuel consumption.

Furthermore, national strategies must be established to improve fuel consumption and energy efficiency and to promote cleaner production schemes in industry

Brazil is leading the way with a high consumption level of ethanol and the great success of flexi fuel cars.

This will surely involve sharp cuts in the consumption of fossil fuels, bolstered by taxes and other restrictions.

Specifications In February 2013, Volkswagen announced that it expected the XL1 to achieve a fuel economy of and emissions of 21 g km of .

Positive developments were also noted with regard to the use of alternative energy systems, such as wind and solar, that help reduce fuel consumption.

In the US, progress is somewhat more decentralized, though new national policies have been adopted, including Corporate Average Fuel Economy (CAFE) standards for automobiles.

The end result is a car capable of producing less than 100g km of CO2 with a stated fuel economy of 74.3 mpg (3.8 l 100 km) on a combined cycle.

Hybrid vehicles, which use an internal combustion engine combined with an electric engine to achieve better fuel efficiency than a regular combustion engine, are already common.

Re balancing the economy from gas guzzling to energy saving and from private to public consumption is bound to alter the goal of economic policy.

Rather than acknowledge that high fuel prices are the best way to inspire energy conservation and innovation, the Bush administration has instituted huge subsidies to American farmers to grow grains for bio fuel production.

(b) Efficient use of process heat and steam reduces industrial fuel consumption resulting in productivity increases, lower energy bills and improved industrial competitiveness

Vivid images have stuck in people s minds from that episode long lines of cars at gas stations, people riding bicycles to work, gasless Sundays and other rationing schemes.

In terms of total lifecycle costs, these vehicles are three to six times more energy efficient than their petroleum counterparts.

Oil price rises from 2003 have been linked to a decline in per capita fuel use for private vehicle travel in the USA, Britain and Australia.

A narrow focus on, say, developing better batteries, improving fuel efficiency, or making automobile production more sustainable is inadequate to catalyze the needed transformation.

This will reduce the world price of these fuels, inducing other countries to consume even more than they otherwise would.

No till or minimum tillage agriculture is also less labour intensive, as it reduces wear and tear on machinery and reduces fuel consumption.

In addition, the environmental and national security arguments in favor of discouraging fossil fuel consumption work better if the increase in energy prices is phased in gradually.

The holiday season that is now upon us is a time for festivity, and usually of overeating. But the rampant consumption of sugar that marks this time of year is nothing to celebrate.

For example, the World Bank claims that in order to be green, we need to take into account that consuming fossil fuels will deprive future generations of those resources.

According to Jordan, the damage to rangelands and loss of rangeland productivity and wildlife habitats were the result of severe overgrazing by the livestock of the refugees, vehicular traffic and the excessive use of plants for fuel by the refugees in the Jordanian Badia.

But rapid urbanization is driving up industrial fossil fuel consumption and household water consumption, and is increasing demand for food in areas where arable land is scarce.

With greater investments, it will be possible to raise farm yields, lower energy use to heat and cool buildings, achieve greater fuel efficiency for cars, and more.

The rich world should commit to financing a massive program of technology development renewable energy, fuel efficient cars, and green buildings and to a program of technology transfer to developing countries.

Over exploitation of living marine resources through excessive fishing continues to be of grave concern to the international community.

Both may be necessary, because, while average fuel economy has made slight gains in recent years, the longer distances that people are traveling have offset any improvement.
