Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [1].
There are 6,923 trillion cubic feet (Tcf) of proven gas reserves in the world as of 2017. The world has proven reserves equivalent to 52.3 times its annual consumption. This means it has about 52 years of gas left (at current consumption levels and excluding unproven reserves).
But natural gas has dirty secrets that news—and energy—consumers ought to hear. Natural gas is mostly methane (CH4), a super-potent greenhouse gas, which traps 86 times as much heat as CO2 over a 20-year period. And even over the course of a century it is still far more damaging than carbon dioxide.
When methane is produced from non-fossil sources such as food and green waste , it can literally take carbon out of the air. However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change.
When natural gas is burned completely, only water and carbon dioxide are produced. Neither is toxic. But when the mixture of fuel and oxygen is out of balance, carbon monoxide may be produced. It is a deadly poison.
Natural gas produces less pollution and greenhouse gases than its counterparts, according to the Center for Liquefied Natural Gas. For example, when natural gas is burned, it produces 45 percent less carbon dioxide than coal, 30 percent less than oil and 15 percent less than wood.
Natural gas is the cleanest fossil fuel. When burned, natural gasproduces about 45 percent less carbon dioxide than coal, about 30 percent less than oil, and about 15 percent less than wood. Natural gas is extremely efficient when it combusts, producing heat, water vapor and carbon dioxide.
On a global level, gas is also safer than heating oil for the planet because natural gas sends 25 percent less carbon dioxide into the atmosphere than oil.

Natural Gas Emits Carbon Dioxide: One of the biggest disadvantage of natural gas is that it emits carbon dioxide which is bad for our atmosphere. Constant introduction of carbon dioxide into our atmosphere will lead to climate change and also global warming.
Natural Gas Liquids and Petrochemicals. Methane - One carbon atom; chemical formula CH4. The principal use of methane is as a fuel. The natural gas that is delivered to your home is almost pure methane.
natural gas cost comparison. If the natural gas cost is $15.00 per 1,000 cubic feet, the same $15.00 will purchase around one million BTUs, this is the equivalent of slightly over 11.20 gallons of propane. If propane costs $2.50 per gallon, in this example, natural gas is the cheaper alternative.

Natural gas is produced in 32 states. The top producing states are Texas, Oklahoma, New Mexico, Wyoming, and Louisiana, which produce more than 50 percent of U.S. natural gas. These are the areas of the United States and Canada where natural gas formations are found.
In general, combustion is the reaction with dioxygen. Oxygen gas is the oxidant and is generally reduced to oxides…whereas the fuel is formally oxidized… Hydrocarbons provide a rich source of examples for combustion. Complete combustion leads to the generation of carbon dioxide and water…
Natural gas is a relatively clean burning fossil fuel
Burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) than burning coal or petroleum products to produce an equal amount of energy.Natural gas emits less carbon dioxide than coal and other fossil fuels. This has led to widespread support for replacing other fossil fuels with methane, the main component of natural gas. There's only one catch—methane is actually a far more potent greenhouse gas than carbon dioxide.
It is 34 times more potent than carbon dioxide at trapping heat. An estimated one to nine percent of all natural gas produced escapes into the atmosphere, equivalent to the global warming emissions from 35 – 314 typical-sized coal power plants (600 megawatts).
When fossil fuels are burned, oxygen combines with carbon to form CO2 and with hydrogen to form water (H2O). These reactions release heat, which we use for energy. The amount of CO2 produced depends on the carbon content of the fuel, and the amount of heat produced depends on the carbon and hydrogen content.
Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [1].
Pounds of CO2 emitted per million British thermal units (Btu) of energy for various fuels
| Coal (anthracite) | 228.6 |
|---|
| Diesel fuel and heating oil | 161.3 |
| Gasoline (without ethanol) | 157.2 |
| Propane | 139.0 |
| Natural gas | 117.0 |
Therefore one gallon of gasoline produces about 217.5 moles of water. Each mole of water has a weight of 18 grams. So the burning of one gallon of gasoline produces 3,914.6 grams of water. This is equal to 8.6 pounds of water, which has a volume of 1.033 gallons.
Natural gas is often praised as a clean energy alternative. It burns more cleanly than other fossil fuels, emitting lower levels of harmful emissions such as carbon monoxide, carbon dioxide and nitrous oxides. It produces less greenhouse gases than other fossil fuels do.
Combustion of natural gas is the chemical reaction of oxygen with a combustible material which produces heat. There are three requirements for combustion. If one of these three components is missing, combustion cannot occur. Oxygen.
Natural gas is often praised as a clean energy alternative. It burns more cleanly than other fossil fuels, emitting lower levels of harmful emissions such as carbon monoxide, carbon dioxide and nitrous oxides. It produces less greenhouse gases than other fossil fuels do.
Natural gas is most commonly extracted by drilling vertically from the Earth's surface. From a single vertical drill, the well is limited to the gas reserves it encounters.
