What are the advantages and disadvantages of natural gas for our planet?

  • Natural gas (largely methane) burns more cleanly than the other fossil fuels (45% less carbon dioxide emitted than coal and 30% less than oil)
  • It is easily transported via pipelines and fairly easily using tankers (land and sea)
  • It can be piped into homes to provide heating and cooking and to run a variety of appliances.
  • Where homes are not piped, it can be supplied in small tanks.
  • It can be used as a fuel for vehicles (cars, trucks and jet engines) where it is cleaner than gasoline or diesel.
  • It is used to produce ammonia for fertilizers, and hydrogen, as well as in the production of some plastics and paints.
  • It's relatively abundant, clean burning and seems easy to distribute.
  • It's also lighter than air, so if there is a leak it will tend to dissipate, unlike propane, which is heavier than air and pools into explosive pockets.
  • It can be used for heating, cooking, hot water, clothes dryer, backup generator power, and so forth.
  • Some places will supply it to your house by way of underground pipes.
  • Natural gas is more economical than electricity,
  • it is faster when used in cooking and water heating and most gas appliances are cheaper than electrical ones.
  • Gas appliances also do not create unhealthy electrical fields in your house.
  • Even though it is cleaner than coal and oil, it still contributes a large amount of carbon dioxide to greenhouse gases.
  • By itself natural gas is mostly methane, which is 21 times more dangerous for greenhouse warming than carbon dioxide so any leakage of the gas (from animals, landfills, melting tundra, etc) contributes strongly to greenhouse emissions.
  • If your house is not properly insulated it can be very expensive.
  • It can leak, potentially causing an explosion.
A:1. Natural gas use requires a separate and special plumbing system inside structures.

2. Natural gas is colorless, tasteless, AND IS ODORLESS IF IT IS NATURAL, requiring the addition of an odorant [one or more of several "Mercaptans"] to allow olfactory detection [smell] of leaks.

3. When gas from an underground leak travels great distances [underground], the odorant can be "scrubbed out" of the gas, thereby rendering it again ODORLESS, and therefore a severe explosion and fire hazard.

4. Being a fossil fuel, it is carbon based, and its byproducts of combustion include carbon compounds [such as carbon dioxide and/or monoxide] which contribute to the environmentally damaging "greenhouse effect."


One disadvantage is that burning it creates CO2 emissions (although not as much as oil or coal), and CO2 is a greenhouse gas. Natural gas itself is actually a very strong greenhouse gas also (much more than CO2 in fact). Another disadvantage is that it can leak and cause fires and/or explosions.

A:As noted above, Natural Gas is a fossil fuel. I am skeptical of calculations that it produces less carbon dioxide than other fossil fuels, although it does burn cleanly and efficiently.

In some places, Natural Gas is considered a waste gas, and excess methane is just burnt in the atmosphere without using any of the energy it carries. For efficiency, we should be utilizing all of our fossil fuel hydrocarbons.

Some communities are now investing in recovering natural gas from garbage dumps and farming for energy production. There is more of this that we could be doing.

As far as fueling automobiles with either Compressed Natural Gas (CNG) or Liquid Natural Gas (LNG), the refueling process is slow (slower than using propane), and high pressures are required. And there are dangers of carrying around CNG or LNG tanks in vehicles.

A:If we are to believe scientists concerning global warming, we need to look at the two products here. Natural gas is mostly methane (as previously pointed out). Natural gas also escapes into our air naturally. Methane is many times more of a forcing agent in terms of green house effect. Converting methane into Carbon dioxide (a less substantial green house gas) would reduce our overall forcing in terms of real forcing.

There are several advantages to using compressed natural gas (CNG) to power vehicles. First, it is the cleanest burning fuel available. This reduces harmful emissions, which helps air quality. Secondly, there is an abundance of natural gas right below our feet. Increasing the production of natural gas would make the US less reliant on foreign sources for its energy, which would also help its national security. Third, as a result of the abundance of natural gas, it is much cheaper than diesel or gasoline. There are many areas throughout the US where natural gas is close to or less than $2 per gallon.
A: The gas orduces lots of energy and is easy to transport using pipelines.

D: It produces more pollution than oil and if it leaks natural gas can cause a big explosion and/or fire


Advantages of natural gas:

- It is a very clean burning fuel

- There is an abundance of it throughout the world - the U.S. has the 6th largest reserve of natural gas in the world

- It is about half the price of gasoline

- It can be used in vehicles and is very efficient

- It is used to heat most homes

- It is easy to recover it from shale

Disadvantages of natural gas:

- There are only about 1,000 fueling stations across the U.S. open to the public

- There aren't very many cars that use it yet
One advantage of natural gas is its abundance in the U.S. Our country has the 6th largest natural gas reserve in the world. Natural gas also has the advantage of being the cleanest burning fuel available.
its renewable!!

it can help keep other gases from the destroying the atmosphere(good for the enviornment)

and it also made vampires decay in the caves back then so there arent any more alive...(or are there?)
Also natural gas is used for fuel... and other things that have to use power
Natural gas is a carbon fuel so burning it generates the greenhouse gas carbon dioxide. However this produces less carbon dioxide than the same amount of energy from burning oil or coal, so natural gas is slightly cleaner than other fossil fuels.

How many kilos of natural gas are in a therm?

1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg

What are the advantages and disadvantages of biogas?

Biogas is methane collected in a power plant from decomposing animal manure and organic matter, which is sometimes grown specially for this purpose.


  1. Firstly, I would like to say that biogas is not a thing to throw away just like that. because, having it will remove the fear that the world will one day face shortage crisis of natural gas. And Government will spend less for imported gas.
  2. Secondly, biogas will encourage majority participation in the natural resources trade, that is, there would no longer be a CARTEL comprising of few nations who control the prices of natural gas, in a monopolistic manner.
  3. Thirdly, biogas would remove this attitude of some nations in the world today, who engage in the practice of using natural gas to sign agreements to assist the other in time of war, and get a certain percentages of this resources as the benefit.
  4. Fourthly, biogas will enable majority of communities in different countries, to participate actively in the power sector, since these raw materials would be extracted from these communities in various countries of the world. And thereby encourage rapid development from the Rural Areas in various countries of the world.
  5. Fifth, biogas will encourage large production output, and less production cost, due to the fact that we would no longer need to, for instance, go far to order for the resources needed for production, and no TIME WASTAGE, but limited time, due to the fact that everything would become within reach. Furthermore, INFLATION would be completely reduced to the ground, since we would now have enough resources to set a balance in prices of goods and production cost.
  6. Sixth, biogas would bring about JOBs CREATION, and encourages new inventions like chemical experiments, Agricultural development and methods of improving large scale farming. Then, more industries would be created, and a new improved living would be experienced by low income earners in the populace, and this would reduce urban congestion in most countries.


To mention but few;

  1. Biogas would encourage deflation of goods prices, due to many producers, and surplus goods availability to the populace.
  2. biogas will bring about high corruption level, from the top to the lowest level in the public.
  3. pollution would be on the increase both sound, air, and water pollution. due to many industrial waste materials in the society.
  4. There would be FOOD SHORTAGE, in the countries in the world, especially those nations with limited land for food production. And since BIOGAS would involve using raw materials from both cash crops and otherwise. And the fact that not all the nations in the world, have land for farming activities e.g, The nations living on Islands, and others in the deserts. this sets of nations would be denied the necessary means of survival.
A:Advantages of biogas
  • Use as a renewable fuel
  • No additional greenhouse gas emissions (it removes and then releases the same amount of carbon dioxide)
  • Waste is disposed of at the same time and in the same operation
  • Consumes methane that might otherwise leak into the atmosphere and increase the greenhouse effect
  • Biogas can also be used on a small scale, eg a pig farm
Disadvantages of biogas
  • The main disadvantage is the loss of the organic waste for compost or fertiliser
  • Very limited in the quantity of electricity it can produce on the global scale
  • There is little or no control on the rate of gas production, although the gas can, to some extent be stored and used as required.

Why is natural gas so easy to set a light?

Natural gas does not have many carbon atoms in its chain, so there is more than enough oxygen in the surrounding air to burn it. When compared to a long chain hydrocarbon like diesel, which will never burn completely with the normal amounts of oxygen in the air mixture surrounding it, natural gas can be identified as easily flammable as it does not give out a lot of smoke due to incomplete combustion.

Natural Gas

What will happen when natural gas is burned?

There are three possible answers to this question:

1. We will have to wait until scientists create a new type of fuel other than fossil fuel.

2. We may never be able to drive again

3. Nothing as scientists may have created a new fuel

Word equation for the combustion of natural gas?

Natural gas + Oxygen -> Carbon dioxide + Water

eg: CH4 + 2O2 -> CO2 + 2H2O

Where complete combustion of methane (CH4, a natural gas) is achieved.

After stating what precisely is meant by 'natural gas' (could be methane o.s.e.) then, in words, it could be something like:

"One mole of the natural gas 'methane' reacts with two moles of oxygen to form one mole of carbon dioxide and two moles of water"

Well, a simple chemical notation is easier and less ambiguous!

Is natural gas a renewable resource?

Natural gas, methane, the fossil fuel, is NOT a renewable resource.

Natural gas, methane, produced from pig manure and rotting vegetation and collected from landfills IS a renewable resource.

It cannot be renewed from its original source as fossil fuel. Much of the natural gas we are burning now formed in deposits buried during the Devonian period, 300 million years ago. It is possible natural gas could form in as little as 50 million years.

None of the fossil fuels are considered to be renewable in that sense. But, since natural gas is primarily methane, and methane is readily available and obtainable from renewable sources other than gas wells drilled into conventional underground reservoirs, it can be considered renewable.

Methane can be derived from organic matter undergoing decomposition. For example in many parts of India, methane is generated through decomposition of both human and livestock feces, gathered and used as cooking gas. Methane can be recovered from organic matter decomposing in land fills and through processing of animal waste. .

How do you identify natural gas contamination of water wells?

In addition to having the water chemically tested - the easiest way would be turn on a spigot (preferably an outside one) and then hold a lighted match near it. If a flame lights where the water spout is, that's pretty good proof.

What are the pros and cons of an electric heat pump versus a natural gas pool heater?

An electric heat pump needs heat available to pump. If it is 30 degrees outside, heating a spa to 102 or so, may be impossible unless the heater has some type of alternative heat source. A properly sized, gas fired heater can take care of a larger range of heating needs. A combination heat pump and natural gas heater, probably with a controller, really makes the issue more difficult, expensive, and would require a lot of study for efficient, cost effective operation. Bottom line: In really mild climates a heat pump might do the job. In cooler climates the gas heater rules. And where a wide range of temperatures and high heat demand is wanted by the customer, a gas heater is the only way to go. A backup heat pump may take years to payout. HM Louisiana

How do you hook up a natural gas appliance?

It is easiest if the gas line and the electrical outlet are already set up in your home. At that point, it is easy to set up the appliance.

When hooking up a new or used gas appliance it is required that you use a new gas line. I always try to use a flexible line and make sure it is extra long so the appliance can be moved in and out. Shut the gas off at the valve and remove old gas line and replace with a new one. They do have different sizes, so you can take the old one to your nearest home depot type store to ensure the correct size. They also have the needed fittings to do most jobs,always use thread compound on the joints and check for gas leaks when done with soapy water..Good Luck.

Consult with a legally licensed gas fitter/plumber. If you do it and something goes awry you will not be covered by your home insurance and you really don't want it to happen now do you. Best it be legal and done rite...

Burning coal usually produces more soot than burning natural gas or petroleum products because coal?

Basically, it is extremely difficult to get solids to burn. It is even somewhat difficult to get liquids to burn! Gasses burn. Heat turns liquids or solids to gasses and then they burn. In a car engine, fuel injectors turn the gasoline into a fine spray which quickly evaporates into a gas. It then burns.

Coal does not burn. A fire heats coal. Then coal gives off gasses. The gasses burn. Then the coal gets hotter. As the coal gets hotter, some of the carbon in the coal turns to gaseous carbon, some of the carbon does not, those flakes of carbon become soot. The carbon gas burns. Some stuff simply is left.

Where does natural gas get its energy?

It gets its gas from being pressed under the ground for thousands of years and gets burned into gasoline.

How long before the world's supply of fossil fuels such as coal oil and natural gas - are estimated to run out?

To understand the issue more fully you need to understand 'Peak Oil', the point when oil production reaches its maximum and after which it goes into irreversible decline. Although this is roughly halfway through all reserves, after this point oil becomes increasingly expensive and difficult to extract. Since demand for oil will outstrip supply the price will drastically increase after the peak and have huge effects on oil dependent industries: transport, agriculture, manufacturing, the military, medicine and many more.

Many people think the Peak is imminent (within 10 years) or has already happened. Coal reserves can be expected to peak later, in the next 20 - 50 years, but as the world's population keeps growing and consumption of fossil fuels increases (despite the known effects to the climate), it is difficult to predict. Of crucial importance is the fact that the development of alternative, renewable energy sources (wind, solar, nuclear fusion) are reliant on oil use.


Oil in about 50 years. Natural gas in about 70 yrs and coal in about 250 yrs.

A:At current consumption and the population growth, scientists have determined that the oil supplies will run out in 500 years. A:Our coal will run out in about 40-50 years at the rate we are going at, according to scientists. If we use less coal and more renewable sources, it is sure it will last much longer, but the high demand for coal in industry is always rising as our world modernizes. A:it takes 500-1000 years A:pessimistically 30-40 years, optimistically ~100


Get real people. We have only been using oil for a little over a hundred years in any real capacity. If we have already reached peak production, and usage is increasing every day, than we are in trouble. Cant be too many years left!

Natural Gas

How do you convert a stove from propane to natural gas?

Answer 1Due to differences between natural gas and propane, they require differing amounts of gas supplied to the burner. This is controlled by the size of the opening where the gas goes into the burner. The mechanism for control is called an "ORIFICE," which usually is made of brass, and looks like a short, fat bolt, with a tiny hole at the center of the bolt head. The difference between the orifices for each gas is accomplished simply by varying the size of that hole.

There is a conversion kit that you can buy at the hardware store. It is fairly simple to do.

Typically it involves switching out orifices, which look like a short bolt with a hole in the middle. Take out the old, put in the new.

Answer 2I don't understand what you mean by "stove." If you refer to a space heater with ONE BURNER AND ONE CONTROL VALVE, then you only have to change ONE ORIFICE. BUT, if your are refering to a kitchen range or cookstove, then you will have to replace the orifice IN EACH BURNER, INCLUDING THE OVEN(S).

To make the conversion, you must install the proper sized orifice for the gas you will be using in the heater or stove. For the sake of simplicity, the following directions are for a single burner space heater. For a multi-burner heater, or a cook stove, make the change at each burner. To change an orifice:

1. Turn off the gas supply STOP valve [valve at the wall, to which the flexible metal gas line ("hose") is attached].

2. Disconnect the flexible gas line from heater inlet [usually on the ON-OFF control valve on the heater].

3. With an adjustable wrench, or an open end wrench, remove [counterclockwise] the heater's control valve. Located on the end opposite from where the gas line was attached, is the orifice [it looks like a brass pipe plug (hex head) with a small hole in the center of the hex head]. It is the size of this hole which determines the rate of gas flow.

4. Two wrenches will be required for this step. Using one wrench on the hex head of the orifice, and another wrench on the hex shoulder of the control valve, unscrew [counterclockwise] and remove the orifice from the valve. I recommend that ANY time you disassemble threaded devices, that you use a wire brush to CLEAN ALL THREADS, which will make reassembly easier.

5. Although not required by Code, apply three or four turns of TEFLON thread seal tape to the "NEW" orifice threads.

6. Carefully by hand, so as NOT to crossthread, screw the new orifice into the valve body as far as possible.

7. Again using two wrenches, tighten the orifice into the valve body, clean the threads of the valve body, and apply a few turns of Teflon tape to those threads.

8. Fully hand thread the valve body back into the cast iron burner, and tighten with a wrench being careful, near the end, to stop when the control valve hand lever is on top.

9. Clean the hose coupling nipple threads on the valve and reconnect the metal "hose" [NO tape is required on these coupling threads].

10. Prepare a "test" solution of a few drops of liquid dishwashing detergent in about half a cup of water. With a paintbrush, whip solution into a bubbly "froth."

11. Turn gas ON at the wall stop, and OFF at the heater control valve, and "paint" the soap froth onto all joints.

12. Watch for new/"growing" bubbles for a few minutes. If bubbles form, you have a leak, and must retighten the joint, or install Teflon tape. If there is NO CHANGE in the bubble layer, the joints are tight and the heater is ready to use.

Answer 3

Most new stoves have both orifices in the control valve. It is a matter of making sure you have the correct one in place. The gases have a different density which results in a different mass of gas being supplied to the burners.

How is natural gas formed?

_">Geologists view crude oil and natural gas as the product of compression and heating of ancient organic materials over geological time. Formation of petroleum occurs from hydrocarbon pyrolysis, in a variety of mostly endothermic reactions at high temperature and/or pressure.Today's oil formed from the preserved remains of algae which had settled to a sea or lake bottom in large quantities under anoxic conditions (the remains of prehistoric terrestrial plants, on the other hand, tended to form coal). Over geological time the organic matter mixed with mud, and was buried under heavy layers of sediment resulting in high levels of heat and pressure (known as diagenesis). This caused the organic matter to chemically change, first into a waxy material known as kerogen which is found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis. In English terms, it's pushed down by pressure, getting every last ounce of everything squeezed out.
