Natural Gas vs. Coal and Renewables
Issues such as emission potential, efficiency, costs, and long-term sustainability come into consideration when comparing natural gas to coal and renewable energy sources.
- Emissions: It generates 50-60 percent less carbon dioxide for every unit of energy when combusted, compared to coal. There are also much lower levels of sulfur dioxide, nitrogen oxides, and other harmful pollutants released during its burn. Still, though cleaner, the natural gas is a fossil fuel and is thus causing greenhouse gas emissions, mainly methane leaks during extraction and transportation. Wind and solar, by contrast, are not emission sources during their operations and are therefore most environmentally benign.
- Energy Efficiency: Coal-fired power plants commonly work at thermal efficiencies of somewhere between 33-40 percent, whereas the modern natural gas plants can go to around 60 percent, or higher, utilizing combined cycle technology. Renewables like wind and solar do not have the thermal conversion step; rather, they directly collect energy from the environment. Their efficiencies are often influenced by geography and weather conditions.
- Cost: Natural gas is usually cheaper than coal, given its abundance and low operational cost advantages, especially in countries with good-quality infrastructure for extraction and distribution. Then again, the renewables, while eventually the future, are now fast closing in on that. There has been a tremendous cost decline for wind energy and solar PV within the last ten years, where in many parts of the world, they are more competitive than coal and natural gas.
- Sustainability: Natural gas is more a dogmatic bridge toward a low-carbon future, and it is still neither renewable nor limitless. Coal continues to decrease in use because it is a primary contributor to climate change and the least sustainable alternative. Meanwhile, renewables such as solar, wind, and hydro provide an unlimited and sustainable option, almost completely in line with the ultimate climate goals.
In an evolving energy space increasingly dominated by renewable energy sources, ever-improving technological advances and policy incentives have put renewables within the realm of strength alternative sources for energy sustainability. However, natural gas stands its ground as a pathway during the transition imparting a reliable, cleaner alternative to coal and supporting grid stability along with intermittent wind and solar sources.
