There are several ways that total underground working gas capacity may be measured. The Energy Information Administration (EIA) estimated in mid 2006 that, after adjustment for operational considerations that hinder the attainment of full storage at all fields simultaneously, a likely practical estimate for maximum industry-wide working gas capacity is roughly 3.6 Tcf. However, based on design capacity estimates, U.S. working gas capacity was 4.01 Tcf as of the end of 2005.

In 2006, the U.S. consumed nearly 22 trillion cubic feet (Tcf) of natural gas by the following seven natural gas end users:

Natural gas is primarily methane, which is a major greenhouse gas. Methane is emitted directly to the atmosphere from sources such as leaks in natural gas wells and pipelines and is produced in landfills, sewage treatment facilities and livestock operations. Other major greenhouse gases, carbon dioxide and nitrous oxides are produced when natural gas is burned for heating and electric power production.

Answer: If you have more music in iTunes than you can fit to Zune, you can choose to update selected playlists only or update manually. With the first option, only the tracks in the selected playlists (rather than the entire music library) are downloaded to Zune when you connect. With the manual update option, you manage what goes into your Zune by dragging and dropping selected songs or playlists into Zune.

EIA does not collect daily spot price information, but instead relies on a private vendor. EIA publishes daily spot prices for the Henry Hub, Transco Zone 6 NY, Chicago, and an average for selected California locations on a weekly basis and these can be found in the Natural Gas Weekly Update (NGWU). A time series of the daily spot price data for these locations and all others in the Lower 48 States are available from the data vendor, Intelligence Press, Inc.

EIA provides international natural gas prices for selected countries by sector (electric generation, household, industry).

In 2005, there were 18.2 trillion cubic feet (Tcf) of dry natural gas produced in the U.S. The top producing states are:

Residential consumers in some States have the opportunity to choose their supplier for the natural gas itself. Suppliers are either the local distribution company or approved gas marketers. Regardless of supplier, the local distribution company continues to provide local transportation and distribution services. Learn More: To find out more about States that have "customer choice" programs, see Natural Gas Residential Choice Programs. Yes.

U.S. residential natural gas prices are projected to average $13.52 per thousand cubic feet (Mcf) this winter , 6.3 percent higher than last winter’s price of $12.36 per Mcf.

Numerous underlying factors affect natural gas prices. Depending on the factor-for example, production, imports, demand, oil prices, and natural gas inventories -- each can apply either upward pressure () or downward pressure () or neutral pressure on prices (). Increasing Production - Total domestic production of dry natural gas is projected to increase 1.4 percent in 2007 and is expected to increase an additional 1.3 percent in 2008.

In 2005, nearly 58 percent of all households (residential sector) used natural gas as their primary heating fuel accounting for about 22 percent of total natural gas consumed in the United States.

The entry of CNG vehicles into garages and similar areas is regulated in an Informational Document of the Ministry of Transport of the Czech Republic, in Article 61(d) and (e): d) it is prohibited to enter closed warehouse, garage and similar areas where the entry of vehicles propelled by CNG or LPG is not expressly permitted, e) before a vehicle enters a repair workshop or communal garage, the responsible member of staff at this structure must be informed that the vehicle is run on CNG or LPG.

ANSWER: Natural gas and propane prices have shot up recently as well. And remember, in most states where oil has a significant market share, oil has been cheaper than gas for nine of the past 10 years.**

Under gas transportation, you will have the option of purchasing your supplies from Columbia Gas or from an alternative gas supplier. Columbia will continue to deliver the natural gas to your facility, but the purchase function will be handled by the company of your choice. This method of natural gas purchasing is similar to the telecommunications industry where you choose a long distance provider.

Natural gas may be stored in a number of different ways. It is most commonly stored underground under pressure in three types of facilities. The most commonly used in California are depleted reservoirs in oil and/or gas fields because they are more available. Aquifers and salt cavern formations are also used under certain conditions. The characteristics and economics of each type of storage site will dictate its suitability for use.

There are no transportation natural gas pipelines in the City of Bedford. There are numerous lines in Bedford that distribute gas which is suitable for home use.

underground storage tank or underground storage tank system means one or more stationary devices, including any connected underground pipes, designed to contain an accumulation of petroleum, of which the volume, including the volume of underground pipes, is 10% or more beneath the surface of the grade. DEC's definition is essentially the same as EPA's, although Alaska does not include tanks that store Hazardous Waste. Please see regulations governing UST's (18 AAC 78) for more information.

No. Natural gas is a commodity and its price is determined by the market, based on several factors. When Nicor Gas buys gas on your behalf and delivers it to your home, we charge you exactly what we paid for it-we are not allowed to mark it up, by regulation of the Illinois Commerce Commission. The cost of natural gas makes up about 75-80 percent of your bill. The delivery charge makes up about 10-15 percent, and taxes make up the remaining 5-10 percent.

Answer: Natural gas is a lighter gas than propane. Liquid propane gas contains 2,500 BTUs per cubic foot, while natural gas contains 1000 BTUs per cubic foot. It takes twice as much natural gas to reach the same BTU rate as propane. Natural gas enters your home through a pipeline from a local supplier and propane is stored in a tank.

When entering into a purchase agreement and capacity is an issue, there are a number of alternatives that may enable the transaction to proceed even though capacity is in some doubt. These include - Joint ownership or tenancy with someone who does have capacity. Note that in the case of joint ownership the person does not have to live in the property so for example another member of the family can jointly own with a disabled relative.

The portion of the nameplate capacity that has natural gas listed as its primary fuel by NERC region is as follows:

The greenhouse gas estimates presented here are full fuel-cycle estimates, combining the three major greenhouse gases emitted by motor vehicles: Full fuel-cycle estimates include all steps in the use of a fuel, from production and refining to distribution and final use. This gives a more complete picture of the climate change impacts of using a particular fuel. Some greenhouse gases have greater impacts on climate than others.

Currently, cavern air storage is in use in two other CAES locations: a 110 MW facility in Alabama and a 290 MW facility in Germany. Using similar storage methods, natural gas is stored underground in many locations around the world, including several locations in Iowa.

Heating oil companies that offer tank protection do not cover the cost of cleanups which may be related to pre-existing tank or oil leaks which are found when a homeowner converts to gas. The entire cleanup cost may not be covered by tank protection. Sellers and potential home buyers should be aware and correct problems with the oil tank to avoid any concerns regarding liability and avoid the possibility of a delay in closing.

One word - LEAKS! Florida’s groundwater is at or near land surface in many areas of the state. Even when ground water lies deeper beneath the surface, Florida’s porous limestone rock and sandy soils allow easy percolation of leaked or spilled contamination into the aquifer. Also, because of the generally high water table, many tanks and their piping are buried in damp soils or even in the groundwater. This promotes corrosion.

Natural gas is one of the safest forms of energy available. Because natural gas is 40% lighter than air, it will dissipate harmlessly into the air in the unlikely event of leak. Heritage Gas adds an odor, similar to the smell of a skunk or rotten eggs, to natural gas so that you’ll quickly know if there’s a problem. This allows even the smallest leaks to be detected, thus enabling repair situations to be identified immediately….your nose is your natural gas leak detector.

Heritage Gas is responsible for the local distribution of natural gas from the main pipeline to the meter at your home or business. You will have the option to purchase natural gas from us and in the future a gas marketer licensed by the Nova Scotia Utility and Review Board.

As long as your supplier arranges delivery from the well to our distribution lines, we will deliver it to you from there. It will not affect Columbia. In fact, we want you to have the choice of purchasing your gas from other sources. There is no profit for us in the cost of gas. That cost is simply passed along to the customer dollar-for-dollar. Our income is derived from the delivery of gas to our customers, and that is not affected by who supplies the gas.

Converting natural gas to a liquid reduces its volume by about 600 to 1, which means one LNG tanker can transport enough LNG to equal 600 tanker ships carrying natural gas. Liquefying natural gas makes it feasible to transport natural gas by tanker and to store it in preparation for re-gasification and delivery to markets.
