Natural Gas Substitution for Coal Keeps Reducing Emissions

Natural gas substitution for coal in electric power generation has consistently reduced carbon emissions on that score, making it the best of all tools.

The Energy Information Administration (EIA) keep count and the score on carbon emissions from electric power generation just keeps getting better. Why? Because natural gas substitution for coal in the electric power sector is sill taking place, reducing emissions associated with coal. EIA, in fact, tells us “Total energy-related CO2 emissions fell in 2016 and are projected to fall in 2017 and rise in 2018, based on EIA’s latest Short-Term Energy Outlook projection.”

Yesterday’s Today In Energy post at EIA spells it out:

In the United States, about 90% of coal is consumed in the electric power sector. Among the top 10 states with the largest coal emissions reductions in 2015, the electric power sector’s share of coal consumption ranged from 98% in Texas to 76% in Pennsylvania, based on data from EIA’s State Energy Data System. In 2015, Illinois had the largest decline in industrial coal consumption, followed by Alabama and Indiana.

Changes in the electric power sector accounted for most of the decline in coal emissions in 2015. Power plant operators reduced generation from existing coal-fired units in response to competition from lower-priced natural gas. In addition, nearly 15 gigawatts (GW) of coal-fired electric generating capacity were retired in 2015, or about two-thirds of all retired capacity that year, based on data in EIA’s annual survey of electric generators. Many of those retirement decisions were likely affected by compliance deadlines associated with the Environmental Protection Agency’s Mercury and Air Toxics Standards rule, which had an initial compliance date of April 2015.

Natural gas substitution for coal is vividly evident in this EIA chart:

Here’s what’s happened, according to EIA:

Most of the 2015 decrease in coal-fired electricity generation was replaced with increases in natural gas-fired generation. For the entire United States in 2015, coal-fired generation fell 15%, by 228 billion kilowatthours, and natural gas increased 20%, by 204 billion kilowatthours, relative to the previous year. The natural gas fleet was being used more often, and the utilization rate of natural gas combined-cycle generators exceeded that of coal generators for the first time in 2015.

Importantly, the decrease in coal-related CO2 emissions in 2015 were far greater than the increase in CO2 emissions associated with that natural gas consumption. Coal-related CO2 emissions across all sectors decreased 231 million metric tons from 2014 levels, in fact, while natural gas-related CO2 emissions across all sectors increased a mere 43 million metric tons.

The 199 million metric tons difference represents a huge net decline in carbon emissions. Moreover, “because natural gas is less carbon intensive than coal, about 80% more energy was provided by the natural gas (28.2 quadrillion British thermal units) consumed in 2015, compared with coal (15.5 quadrillion British thermal units).”

These are the key facts to know for anyone who truly wants to do something about carbon emissions. Natural gas substitution for coal is the answer. It’s the only thing making a meaningful difference, in fact, which is why Germany’s Energiewende is accomplishing so little at such great cost. Natural gas is simply getting it done here in the U.S. with no fanfare and no massive subsidies while also reviving the rural economies of places like Southwest and Northwest Pennsylvania, Ohio and Texas.

  1. Anti-natural gas activists should take notice of this. Worldwide CO2 emissions increased in 2017 due to the increased use of coal in China. China is importing natural gas in an effort to reduce the emissions from coal, since that is the fastest way to bring down atmospheric pollution and maintain electric power output. Wind and solar will contribute to reduced emissions, but will take much longer to implement and become consistently reliable.

  2. Make way for 100% renewable energy;

    See what Georgetown, Texas has accomplished.
    Georgetown, Texas leads the Nation in being 100% Renewable..
    Wind and Solar.
    Municipal building in Georgetown, Texas has the roof covered in solar panels.
    Wow, what an example for the Nation.
    Red, conservative and Republican and into 100% renewables.
    50,000 population and they decided it was the best choice…

    • Relatively poor example, Vera ‘s been mislead by some promotional cock and bull, in fact to say it is completely 100% Renewable is misleading especially when the mayor has trouble cracking the numbers on the origin of the supposed 100% renewable resource, please take it with a grain of salt..

  3. No city anywhere can achieve 100% renewable energy factoring based on a intermitted, unreliable, energy resource, just not economy globally can survive with-in the parameters of Renewable energy, what is evolving is common sense with-in the Green’s that renewables alone for carbon emission reduction comes at a cost of Trillions with no attainable benefits.Government policy globally is moving towards Hydro. Geothermal. Natural Gas..CNG, in fact the farming sector will move more towards organic natural gas as their principle weapon in emission carbon reduction,CNG being the principle transportation method in the agricultural sectors
