People are not spending all the money they save on gas.

Consumers, in the U.S. at least, are acting cautiously with the savings they're getting at the gas pump, as the memory of the recent great recession is still fresh in their mind.

Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can't buy alcohol at drive-through facilities.

What is the purpose of California's rule about alcohol display in gas stations

Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards while still curbing the emissions of the heat-trapping gases.

How emissions of heat-trapping gases can be reduced on a global scale

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

They can easily switch to natural gas

A study by the University of Manchester calculated the emissions of CO2—the main greenhouse gas responsible for climate change—at every stage of microwaves, from manufacture to waste disposal.

It is profitable to drill to depths more than 1,000 feet for oil and gas extraction, but only recently in California has it become profitable to pump water from this depth.

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

The recent discovery of the giant Zohr gas field off the Egyptian coast will eventually have impact on pricing in the Mediterranean region and Europe, and there is significant development potential in many other places, notably Argentina.

The North American shale gas boom has resulted in record low prices there.

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.

Pricing carbon proves the most economical way to reduce greenhouse gas emissions.

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

Nations from around the world have gathered in Paris for the United Nations Climate Change Conference, COP 21, with the goal of a universal and potentially legally-binding agreement on reducing greenhouse gas emissions.

Greenhouse gas emissions, if not properly dealt with, will pose endless risks for mankind.

Failure to address comprehensively the problem of greenhouse gas emissions, however, exposes all generations, present and future, to incalculable risks.

Coal and natural gas are mainly used for electricity generation, whereas oil is used mostly to power transportation, yet the prices of all these energy sources are linked.

As a country's wealth grows, so do its greenhouse gas emissions.

To be sure, the battery still has a long way to go before the nightly recharge completely replaces the weekly trip to the gas station.

Fewer than 4% of countries are responsible for more than half of the world's greenhouse gas emissions.

Developed nations such as Australia, the United States, Canada, and European countries are essentially climate free-riders: causing the majority of the problems through high greenhouse gas emissions, while incurring few of the costs such as climate change's impact on food and water.

Antarctica's mineral, oil and gas wealth are a longer-term prize.

And while assessments vary widely, geologists estimate that Antarctica holds at least 36 billion barrels of oil and natural gas.

According to geologists' estimates, Antarctica has enormous reserves of oil and natural gas.

It’s no accident that most gas station shave convenience stores attached.

The Conservatives plan to adopt this strategy by making utility companies print the average local electricity and gas usage on people's bills.

That’s energy in all forms--oil, gas, coal, nuclear, solar and even wind power.

Indeed, on a global scale, fertiliser manufacturing consumes about 3-5% of the world's annual natural gas supply.

Short-term oil shortage drove American consumers to wait in long lines at gas pumps.

Left alone, it was assumed, the world's rain forests would not only flourish but might even rescue us from disaster by absorbing the excess carbon dioxide and other planet-warming greenhouse gases.

billion metric tons of carbon into the atmosphere each year - making forests the leading source of greenhouse gases

More than paradise lost, a perishing rain forest could trigger a domino effect - sending winds and rains kilometers off course and loading the skies with even greater levels of greenhouse gases - that will be felt far beyond the Amazon basin.

Each burning season in the Amazon, fires deliberately set by frontier settlers and developers hurl up almost half a billion metric tons of carbon a year, placing Brazil among the top five contributors to greenhouse gases in the world

The author argues that the rising carbon levels in rain forests may turn them into a major source of greenhouse gases.

turn them into a major source of greenhouse gases

What makes Brazil one of the world's top five contributors to greenhouse gases?

In face of global warming, much effort has been focused on reducing greenhouse gas emissions through a variety of strategies.

But what do you do with the gas once you've captured it

Dakota Gasification of North Dakota captures CO2 at a plant that converts coal into synthetic natural gas.

It then ships the gas 200 miles by pipeline to Canada, where it is pumped underground in oil recovery operations

Some propose storing the CO2 in coal mines or liquid storage in the ocean, Shell favors storing CO2 in deep geological structures such as saline(鹽的) formations and exhausted oil and gas fields that exist throughout the world.

For a start, all animals, such as cows, pigs and sheep, always gas limed methane, which is the second most common green house gas after carbon dioxide.

Methane has become the chief source of greenhouse gas.

Developed nations such as Australia, the United States, Canada, and European countries are essentially climate "free-riders": causing the majority of the problems through high greenhouse gas emissions, while incurring few of the costs such as climate chan

Fewer than 4% of countries are responsible for more than half of the world's greenhouse gas emissions.

Heating this chemical compound drives off carbon dioxide gas, leaving calcium oxide.

It stands in sharp contrast to Sanchez, this other gadget, a gas powered flame we killer, invented in 1997.

Sommerkorn says a plan to reduce greenhouse gas emissions blamed for global warming needs to come out of the Copenhagen Climate Change Summit in December.

The gas can be stored under pressure in a tank.

To be sure, the battery still has a long way to go before the nightly recharge completely replaces the weekly trip to the gas station.

To recover the energy, the gas is fed back over the calcium oxide.

According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions more than doubling during the 1992 to 2007 window.

Environmental protection agency notes that most waste is dangerous in that "the production, distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas release".

Gas emissions have been effectively reduced in developed countries.

In 1997, the Kyoto Protocol explained our role in the earth's changing atmosphere and set international limits for gas emissions from 2008 to 2012.

It flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air.

Just how bad was it? The neighbors came out of their houses to see if we had a gas leak!

The effect is so powerful that scientists speak of songbirds and seabirds being"captured"by searchlights on land or by the light from gas flares on marine oil platforms.

While fossil fuels – coal, oil, gas – still generate roughly 85 percent of the world's energy supply, it's clearer than ever that the future belongs to renewable sources such as wind and solar.
