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.
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
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.
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.
