"Truthland" - Energy In Depth reveals the truth about "Gasland"

Natural gas is a clean, abundant and domestic energy source that holds vast potential to promote cleaner air, grow local economies and enhance energy security in the United States. National Fuel and the natural gas community are committed to the safe and responsible development of this energy source. The film "Gasland" has numerous misleading and factual errors. Energy In Depth, a project of the Independent Petroleum Association of America, reveals the truth behind the controversial movie, "Gasland." Click here to view the movie "Truthland."

Natural Gas: Earth and Sky Friendly

Natural gas – the ultimate “alternative” fuel of the future? Yes, the same natural gas first commercially used in the United States in western New York in the early 19th century. When it comes to dealing with issues surrounding pollution and the environment, carbon management and energy security, natural gas is part of the solution, not part of the problem. Yes, natural gas is a “fossil fuel.” But natural gas is far more environmentally attractive than oil, coal, and electricity produced with fossil fuels. Of the major sources of energy in the United States, natural gas is the cleanest, most efficient, cost effective, and abundant, producing less pollution and fewer greenhouse gasses than its counterparts.

Fewer Greenhouse Gas Emissions:

The primary byproducts of burning natural gas are carbon dioxide and water. But natural gas produces LESS carbon dioxide than other commonly used energy sources. According to the federal Energy Information Administration (EIA), natural gas emits 45 percent LESS CO2 than electricity and nearly 30 percent LESS CO2 than fuel oil. In fact, the U.S. is now a world leader in carbon reductions. As acknowledged by the chief economist for the International Energy Agency, the replacement of coal by shale gas was a key factor driving the carbon emission reductions in the U.S.


Natural gas generates less sulfur dioxide (a cause of acid rain), less nitrogen oxides (that can produce smog) and less particulate matter than oil or coal, which is primarily used for electric generation. The cleanliness of gas means that not only does it produce less pollution, but also environmental controls on gas equipment are usually much less expensive than for other fuels. Additionally, technological progress allows cleaner energy production today than in the past. Natural gas use means cleaner air whether used for home space heating, water heating, cooking, clothes drying, and in the case of natural gas vehicles, cars, trucks, buses, and commercial and industrial processes.

More Efficient:

Natural gas appliances are more energy efficient than their electric counterparts, and natural gas users thus conserve energy resources and reduce greenhouse gas emissions. According to the American Gas Association (AGA), while the number of natural gas residential customers increased 71 percent since 1970, the average customer today uses 40 percent less natural gas than they did 40 years ago. By using energy wisely, weatherizing homes, using energy-efficient appliances and installing programmable thermostats, customers reduce greenhouse gas emissions.

Clean Electricity:

Electricity demand is still growing to light our homes and businesses as well as power computers and other electronic devices. Clean-burning natural gas is used to generate an increasing amount of electricity, providing over one-fourth of our nation's electricity in 2013. As older, coal-burning electric generation facilities are phased out for environmental reasons, the nation is relying more on natural gas to reduce pollution and total greenhouse gases produced by electric generation.

Site vs. Source Emissions:

When talking clean and efficient, many people mistakenly think electricity. But how is that electricity generated? When considering all the energy waste in electric generation (the full-fuel cycle), the Gas Technology Institute states that only 32 percent ultimately makes it to the end user. The overall efficiency of natural gas is 92 percent! The highly esteemed National Academies (of Science, of Engineering, Institute of Medicine and the National Research Council) recommended that the Department of Energy (DOE) should consider changing its measurement of appliance energy efficiency to one based on the full-fuel cycle. This more accurate measurement would provide consumers with more complete information on energy use and environmental impacts. For this reason, the EPA uses source energy in calculating the ENERGY STAR performance rating for buildings, designed to improve building efficiency and reduce carbon emissions nationally.

Lower Costs:

Natural gas costs less to use than other major home energy sources. That's according to the DOE Office of Energy Efficiency and Renewable Energy. According to the DOE, the equivalent amount of electricity costs families roughly four times as much on average as natural gas. Natural gas also costs less than heating oil and propane. The least expensive way to heat a home is with a high-efficiency natural gas furnace.

Energy Secure and Abundant:

Natural gas supplies America with more than one-fourth of its total energy consumed and according to the EIA, natural gas consumption will grow more than 23 percent by the year 2040. Unlike oil, which is largely imported, over 99 percent of the United States' natural gas supply comes from North America, 89 percent from the U.S. itself. And in its 2012 supply assessment, the Potential Gas Committee estimated future U.S. gas supply at over 2,688 trillion cubic feet, more than 100 years of America's natural gas supply needs. This increase is largely due to new technologies that are able to unlock newly discovered reserves such as natural gas from shale formations in the Appalachian basin, as well as in the Mid-Continent, Gulf Coast and Rocky Mountain areas.

Natural Gas – Your Most Energy Efficient Choice:

In the coming years, America faces significant energy challenges. Although there are renewable forms of energy on the horizon that show promise, according to the EIA, solar and wind-generated renewable power made up approximately five percent of our nation's energy supply in 2013. Total renewables including hydropower brings the amount of renewable power to 13 percent. Until other alternatives can be produced abundantly and cost-effectively, natural gas, first used commercially in 1821 in western New York, will continue to be the miracle fuel of the future that is available today.
