Pros and Cons of Natural Gas
Natural gas is one of our most important energy sources in our current times.
It is used for many crucial purposes, including energy production and heating.
Even though natural gas has many upsides, there are also many problems related to it.
In this article, the pros and cons of natural gas are examined in detail.

Natural gas has been a quite important energy source over many decades. Thus, it can be regarded to be a quite mature technology that had been optimized over many years. Due to this optimization and maturation process, it can be considered to be one of the most established power sources we as humanity know at a global scale.
Major global source of energy
Since natural gas can be extracted and used in many countries all over the globe, the use of natural gas for energy and heating purposes has become quite popular over time.
The technology and the use of natural gas in the energy production process can be regarded to be relatively safe. Even though there had been a few incidents over time, the use of natural gas has not been responsible for too many fatalities.
Compared to accidents in nuclear power plants where large areas of land will be contaminated with radioactive materials and thousands of people may die from the consequences, natural gas can be considered to be rather safe.
Due to its maturity and the overall acceptance throughout many industries, natural gas can also be seen as a quite reliable power source.
There had been not too many problems in the supply chain related to natural gas over time and there is no reason to believe that this may change in the near future.
Not dependent on weather conditions
Another advantage of natural gas is that power production with gas is independent of outside weather conditions. Compared to alternative energies like wind or solar energy, energy production with natural gas does not need sunlight or wind in order to work.
Thus, natural gas is a quite stable power source, which could be used as a complement to alternative energies until humanity is able to supply enough energy solely by using alternative energies.
Abundant energy source
Even though natural gas is a finite resource, there is still plenty of gas available, which may last many decades or even centuries until it is entirely depleted.
Therefore, in the short run, natural gas will continue to be an important power source until humanity is able to fully replace fossil through renewable energy sources.
Cleaner than other fossil fuels
Although the use of natural gas implies the emission of significant greenhouse gases into the atmosphere, it is considered to be less harmful compared to the use of other fossil fuels like coal or oil.
Thus, if you still want to use fossil fuels for heating or energy purposes, you should go for natural gas instead of coal or oil in order to improve your ecological footprint. However, even better would be to switch to green energies instead.
Less harmful waste by-products than other fossil fuels
While the combustion of other fossil fuels like coal implies the production of harmful by-products, the use of natural gas does not. Therefore, also in terms of waste disposal and hazardous waste production, natural gas can be considered to be eco-friendlier compared to other fossil energy sources.
Natural gas can be accessed in many countries
Since there are natural gas deposits in many countries worldwide, natural gas is a quite popular energy source. Even though the access to natural gas may be harder in poor developing countries since their technological progress is lagging, once those countries become more developed, there would be plenty of natural gas deposits left to access.
Can be used for fertilizer production
While natural gas is quite prominent for energy production and heating purposes, components from natural gas can also be used for fertilizer production.
Hence, natural gas may also be quite beneficial for agricultural purposes, even though fertilizers should not be excessively used since this may lead to serious soil and groundwater pollution.
Existing optimized infrastructure around gas
Since natural gas has been used for many years as primary energy source, there is a huge and optimized infrastructure around this kind of energy. This includes the mining, transportation, processing and energy production in a quite efficient manner.
Many companies and whole industries rely on natural gas as primary energy source, which makes it crucial in the short run to ensure our industrial energy supply.
Efficient energy source
The use of natural gas can also be considered to be quite efficient compared to most alternative energies. Thus, even though natural gas has many problems, it will still play an important role for many years until the energy transition process has been finished.
Can be used for a variety of different purposes
Since natural gas is not only useful in the energy production and heating industry, but may also be used for agricultural processes as well as for many other devices, it is quite versatile and flexible. Therefore, the use of natural gas is quite popular among homeowners as well as in industrial processes.
Cheaper compared to other fossil fuels
Compared to energy production with oil, natural gas is often much cheaper regarding the unit price for energy. Thus, not only from an environmental, but also from an economic perspective might it be senseful to switch from oil to gas heating.
However, switching to green energies like solar power would be even better in order to improve your ecological footprint.
There are plenty of employees in the gas sector right now. In order to ensure or even create more jobs in this industry, it is crucial that natural gas continues to be an important energy source in the future.
However, it should be mentioned that workers in the gas industry might also be able to work in the renewable energies sector if they get proper training.
Thus, the safety of jobs in the natural gas sector should be a rather weak argument for the maintenance of this technology.
Important complement in the energy transition process
Even though natural gas might not have a bright future in the long run, it is still quite important as a complement in the transition process from fossil to renewable energies in order to ensure the energy supply of millions of people worldwide.
Cons of Natural Gas
- Greenhouse gas emissions and global warming
- Natural gas as non-renewable resource
- Air pollution
- Acid rain
- Ozone depletion
- Destruction of habitats through mining
- Biodiversity loss
- Fracking for gas may lead to earthquakes
- Water and soil pollution from fracking
- Dependence on other countries
- Dependence on world market prices for gas
- Transportation of gas may be dangerous
- Initial costs for construction of pipelines is quite high
- High initial costs for homeowners
- Leaks are hard to detect
- Only little room for improvements
Greenhouse gas emissions and global warming
One major problem of natural gas is that it implies the emission of significant greenhouse gases into our atmosphere. Even though the level of greenhouse gas emissions is lower compared to other fossil fuels like coal or oil, it is still much higher compared to many alternative energies.
Since greenhouse gas emissions contribute to global warming, we as a global society should reduce the use of natural gas as primary energy source in order to limit the increase in air and water temperature.
Natural gas as non-renewable resource
Gas is also a finite resource that can also be considered to be non-renewable since the formation of natural gas usually takes millions of years. Thus, even though there is plenty of natural gas left at the current point in time, we as humanity will run out of this resource.
If we haven’t made the transition to renewable energies until this time is reached, we will be in serious trouble since our energy supply might be threatened. Fortunately, countries all over the world put significant efforts in the transition to renewable energies.
Thus, it is estimated that in a few decades, we will be able to meet the majority of our energy demand through the use of renewable resources and natural gas will lose its importance as primary power source.
In the combustion process of gas for energy production, our air is polluted with significant amounts of harmful gases and other toxic components. In turn, this may lead to serious health issues, especially for people living in regions with low air quality and high levels of emissions.
The emission of harmful gases also implies the formation of acid rain. Depending on the severity of emissions, acid rain can lead to serious local environmental issues.
For instance, since plants are usually quite sensitive to the acidity levels of the soil, crop yields may significantly decrease due to acid rain, which may lead to serious levels of poverty and starvation, especially in poor developing countries in which the local population relies on crop yields as a primary food source.
Components in the emissions from natural gas energy production may also contribute to the depletion of the ozone layer. The ozone layer protects not only humans, but also our flora and fauna from excessive radiation. If this layer becomes depleted, serious health issues like cancer may become much more common over time.
Destruction of habitats through mining
Since natural gas has been extracted out of the ground through mining or fracking processes, large areas of land have to be used and processed.
In turn, this may lead to serious habitat destruction since many animals will lose their home and may be forced to relocate. Many plants in the affected regions may also die off.
The destruction of natural habitats through human intervention that is implied by the extraction of natural gas also implies a significant loss of biodiversity. Many plants may not be able to adapt to these new conditions and may suffer from a serious decrease in population.
Moreover, since many animals will lose their natural living conditions, they may also become endangered or even extinct.
Fracking for gas may lead to earthquakes
Even though it has not been proven yet, fracking in the context of the extraction of natural gas is also considered to be able to cause earthquakes.
Hence, the extraction of natural gas may indirectly cause the death of many people and may also destroy important infrastructure of several sorts.
Water and soil pollution from fracking
The fracking process is considered to be quite harmful to our environment. Critics of this technique often point out that it may lead to serious pollution levels.
Since plenty of chemicals are used in the fracking process, it can lead to serious water contamination and soil pollution, which in turn will significantly hurt the local flora and fauna and may also contaminate our groundwater.
Dependence on other countries
Countries that do not have plenty of natural gas deposits may rely on other countries in order to be supplied with sufficient natural gas.
However, this economic dependence also often implies a political dependence, which may often result in rather unfavorable outcomes for the country that is dependent on a specific resource.
Thus, by using renewable alternative energies instead, countries could lower their level of dependence on other countries and therefore increase their political freedom.
Dependence on world market prices for gas
The dependence on fossil fuels like natural gas also implies the dependence on world market prices for those resources. Therefore, countries which still rely on natural gas as primary energy source in the future may get in serious trouble if the world market prices for gas increase dramatically. Hence, switching from fossil to renewable energies might be a good idea also in an economic and political context.
Transportation of gas may be dangerous
There might also be issues related to the transportation process of natural gas. Since gas is highly flammable, transportation accidents may lead to serious explosions and may lead to injuries or even to the death of a number of people.
Initial costs for construction of pipelines is quite high
Even though the unit price for energy from gas is rather low, the initial construction costs for gas pipelines can be quite high. Thus, the overall costs that are implied in the production and distribution chain may be significantly higher than most people might expect.
High initial costs for homeowners
Moreover, also the initial installation costs for homeowners related to natural gas heating might be significant. It can cost up to 30,000 USD to buy and install a natural gas heating system.
Therefore, this money might be better invested in alternative green energies like solar power since natural gas might lose its importance in the long run.
Leaks are hard to detect
Since natural gas is odorless and invisible, it is quite hard to detect leaks. Thus, most of the leaks are only detected once its too late and explosions have taken place. This makes natural gas quite dangerous, especially for people who are not experienced in the handling of this resource.
Even though the number of accidents related to the use of gas heating or energy production is rather low, there are still some people dying from those accidents every year.
Thus, switching from fossil fuels like gas to safer technologies like solar power would not only be beneficial for our environment, it might also increase your overall safety level.
Only little room for improvements
In contrast to many alternative energies which have still huge potential for technological advancements, the technologies related to natural gas are quite mature and only have little room for improvements in efficiency.
Hence, at one point in time, natural gas may lose its importance due to efficiency improvements related to other alternative energies.
