• 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.

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.

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.

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

Answer:

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.

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

ADVANTAGES

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.

DISADVANTAGES

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.

• 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

• 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.

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!

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. .

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:

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!

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.

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.
