Is Natural Gas Renewable or Nonrenewable – The Verdict

Natural Gas

As one of the primary fuels powering our homes, industries, and electricity generation, the nature of natural gas—whether it can be considered a part of our sustainable energy future or a relic of our fossil-fuel dependent past—has profound implications.

The classification of natural gas as a renewable or nonrenewable resource is a topic of significant debate and importance. Both sides of the argument come with solid claims for their theories. Today, we would like to discuss this subject in a greater detail.

Key Takeaways:

  • Despite different theories, natural gas is classified as nonrenewable.
  • Natural gas cannot sustainably meet long-term energy needs.
  • The extraction process poses significant environmental risks.

Is Natural Gas Renewable?

Is Natural Gas Renewable

Natural gas is not a renewable resource. It is primarily composed of methane, and is a topic of debate when discussing renewable versus nonrenewable resources.

The main reason for it to be considered like this is its formation from organic matter over millions of years, making its replenishment rate significantly slower than its consumption rate.

Type of Methane Source Renewable or Nonrenewable Environmental Impact
Traditional Methane Fossil Deposits Nonrenewable High (Extraction and use lead to significant environmental degradation)
Biogenic Methane Landfills, Agricultural Settings Potentially Renewable Mixed (Contributes to greenhouse gas emissions, but renewable aspect offers potential for sustainable use)

Renewable vs. Nonrenewable Energy Sources

Renewable energy sources

The distinction between renewable and nonrenewable energy sources is crucial in understanding our impact on the environment and how we can sustainably power our future. Renewable energy sources, such as wind, sunlight, and water, are characterized by their ability to naturally replenish.

These sources are virtually inexhaustible and can be utilized repeatedly, making them a cornerstone for sustainable energy policies. In contrast, nonrenewable energy sources, including natural gas, coal, and oil, originate from finite resources that took millions of years to form.

Energy Source Type Characteristics
Solar Renewable Derived from sunlight, inexhaustible, and clean.
Wind Renewable Generated from wind, sustainable, and emits no greenhouse gases during operation.
Hydroelectric Renewable Produced by moving water, renewable, and capable of generating large amounts of electricity.
Natural Gas Nonrenewable Extracted from beneath the Earth’s surface, finite, and emits CO2 when burned.
Coal Nonrenewable Mined from the Earth, abundant but finite, and highly polluting.
Oil Nonrenewable Drilled from underground reservoirs, finite, and used for transportation and heating.


Once consumed, these cannot be replenished within a human timeframe, leading to depletion and various environmental concerns. The key difference lies in the sustainability and environmental impact of these resources, with renewable sources offering a path towards a cleaner, more sustainable energy future.

Environmental Impact of Natural Gas

Environmental Impact of Natural Gas

The environmental footprint of natural gas, while less pronounced than other fossil fuels, still poses significant challenges and concerns. The process of extracting natural gas, particularly through hydraulic fracturing or “fracking,” has been linked to various environmental issues.

This method involves injecting high-pressure fluid into shale beds to release gas, which can lead to water contamination through the leakage of fracking fluids into groundwater. The disruption of land for natural gas extraction can lead to habitat destruction, affecting local wildlife and ecosystems.

The seismic activity associated with fracking has also been implicated in causing earthquakes in areas previously considered geologically stable. Methane, the primary component of natural gas, is a potent greenhouse gas with a global warming potential many times greater than that of carbon dioxide over a 100-year period.

Methane leaks from pipelines, natural gas wells, and other infrastructure are a significant source of greenhouse gas emissions, undermining the potential climate benefits of switching from coal to natural gas.

These leaks not only contribute to climate change but also represent a loss of a valuable energy resource. When combusted, natural gas does produce fewer pollutants than coal or oil, including lower levels of sulfur dioxide, particulate matter, and nitrogen oxides, which are beneficial for air quality.

The Future of Natural Gas

The Future of Natural Gas

The future of natural gas is at a pivotal crossroads as the global community intensifies its search for sustainable energy solutions. Amidst this search, Renewable Natural Gas (RNG) is a beacon of potential, offering a pathway to mitigate some of the environmental detriments traditionally associated with natural gas.

RNG, derived from the decomposition of organic waste in landfills, agricultural processes, and wastewater treatment plants, represents a circular approach to energy production, transforming waste into power and significantly reducing methane emissions—a potent greenhouse gas.

Including RNG into the existing natural gas infrastructure could seamlessly transition the energy sector towards more sustainable practices without the need for extensive new pipelines or technologies. This compatibility with current systems makes it an attractive option for immediate reductions in greenhouse gas emissions, aligning with global climate goals.

The scalability of RNG production and its capacity to fulfill the burgeoning global energy demand pose significant hurdles. The current production levels of RNG are insufficient to replace conventional natural gas entirely, necessitating continued innovation and investment in this area.


What will replace natural gas?

Renewable energy sources like solar, wind, and hydroelectric power are poised to replace natural gas. Advances in battery storage and green hydrogen technology also offer promising alternatives for heating and electricity generation.

How much CO2 is in natural gas?

Burning natural gas releases about 0.2 kilograms of CO2 per kilowatt-hour (kWh) of electricity generated, making it cleaner than coal but still a significant source of carbon emissions.

What is the cleanest energy source?

Solar and wind energy are considered the cleanest sources of power due to their minimal environmental impact, lack of greenhouse gas emissions during operation, and sustainable nature.

Is natural gas ever liquid?

Yes, natural gas can be cooled to a liquid state at about -162 degrees Celsius (-260 degrees Fahrenheit) to become Liquefied Natural Gas (LNG), which is easier to store and transport over long distances.

The Bottom Line

While natural gas plays a significant role in the current energy landscape, its classification as a nonrenewable resource and its environmental impact highlight the urgency for a transition to renewable energy sources.

The exploration of renewable aspects, such as biogenic methane, offers potential yet does not negate the environmental challenges posed by traditional natural gas extraction and use.
