Ion engines can make much more efficient use of propellant than existing chemical rockets.

And one of the things that we need to do is, not only fix the fuel efficiency of our vehicles and make them much more efficient, but we also need to fix the economy in general.

Increase in price of petrol.

(c) More efficient trade negotiations.

Fuel efficiency standards for automobiles were legislated, and car producers implemented them.

World market prices of fossil fuels will simply be lower than they otherwise would be such that total consumption of fossil and bio fuels rises by the extra production of bio fuel.

Because fuel cells are about twice as efficient as internal combustion engines, the effective cost per unit of distance would be about half that.

The gas tax should be raised , not lowered.

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

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.

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

The Division will consider how to further enhance efficient planning and early implementation of mandates.

Instead, we should focus on inventing new, more efficient green technologies to outcompete fossil fuels.

Regulatory policy can increase the efficiency of appliances, housing, and machinery.

But carmakers think fuel cells are the better, more efficient, silent, clean power source for transportation.

As of 2014, twenty million liters of fuel is trafficked out of Iran every day despite increased domestic fuel prices caused by the Iranian targeted subsidy plan.

(f) Increased efficiency and effectiveness of the Inter Agency Committee on Women and Gender Equality.

Some bio fuels are far more cost effective and energy efficient than others, and different bio fuel stocks have very different opportunity costs for food agriculture (sugar has not experienced any significant price increase).

Agriculture is already responding positively to climate change mitigation through substitution of fossil fuels, continued energy efficiency and carbon sequestration.

Within a thirty four hour period in May 2001, six fuel distributors considerably increased their sale prices of fuel by almost the same amount within the whole national network of petrol stations.

Perhaps the single most promising development in terms of energy efficiency is plug in hybrid technology for automobiles, which may be able to triple the fuel efficiency of new automobiles within the next decade.

Carbon emissions can be reduced through increasing the use of wood (which is a renewable resource), either for durable wood products or for biofuel, in place of fossil fuels.

In order for the whole planet to make a sustainable shift away from fossil fuels, we need to make low carbon energy both cheaper and more efficient.

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

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.

(b) To help improve the efficiency and effectiveness of the respective secretariats in achieving the legislative mandates and the mission objectives established for the organizations

Within the framework of the Nuclear Suppliers Group, Switzerland participates actively in discussions aimed at improving the regime's efficiency.

As well as entailing greater operational efficiency, coordination also meant increasing the coherence of development policies and priorities.

For the less qualified in Western Europe, a decrease in employment will be inevitable, because the scope for wage fluctuation is limited by collective agreements and by the minimum wage levels that the welfare state sets through wage replacement benefits and legal minimum wages.

The review of Iraq's missile projects demonstrates that liquid propellant missiles are the most likely candidates for modification aiming at the extension of the range of a missile through a payload reduction and increase of fuel capacity.

In addition, enhanced HFC 134a systems were being developed to help with energy efficiency and reduce emissions.

It is hoped that the suggested approach would result in increased efficiency and quality of the review with minimal burden on Parties and the secretariat.

But increasing energy access is not only about supplying better, more efficient cooking stoves or light bulbs.

Already, hybrid automobiles, which combine gasoline and battery power, can roughly double fuel efficiency, cutting carbon dioxide emissions by half.

Encouraging investments in renewable energy and increased energy efficiency will have the added benefit of boosting long term self reliance and resilience against the volatility of fossil fuel prices.

Fuel efficiencies in the automotive sector have increased by more than 60 in the past three decades, while overall wealth produced per unit of energy has doubled during the same period.

The protests started after the Palestinian Authority declared an increase of about 8 in fuel and petrol prices in the West Bank, starting from the beginning of September.

In 1977, the US created the Department of Energy (DOE) a year later, it enacted the National Energy Act, which employed tools like industrial regulation and tax incentives to promote fuel efficiency and renewable energy.

Business led innovation and market based solutions can drive a decisive global shift from crippling fossil fuel dependency to more efficient renewable energy systems.

The programme also aims to increase resource efficiency and better management by introducing the concept of cleaner production in participating industrial companies and to strengthen the capacity of local partners.

Provision of education to girls and women at all levels on water issues can promote more efficient water use and water resource management.

According to them, they cause of the protests in Myanmar He said that the fuel hike in July was only the catalyst for something else which has been simmering below the surface among the Burmese people.

And the cozy candles that many participants will light, which seem so natural and environmentally friendly, are still fossil fuels and almost 100 times less efficient than incandescent light bulbs.

To avoid such an outcome, Brazil s leaders must increase the efficiency of government spending and use the freed up resources to clear infrastructure bottlenecks.

Advancing cost effectiveness and market penetration of sustainable energy systems will require technical research aimed at improved energy conversion techniques, supply structures and end user technologies, as well as non technical research into a wide array of related social, political and economic issues.
