A study prepared for New York City Mayor's Office of Long-Term Planning and Sustainability finds gas provides 57% of NYC's energy. www.nyc.gov/html/om/pdf/2012/icf_natural_gas_study.pdf at page 2. NYC is much more dependent on gas than the rest of the country. In fact, NYC gets twice as much of its total energy from gas as America does (gas accounts for about 28% of America's total energy).
The study further concludes that gas provides substantial climate benefits, compared to coal or oil. Specifically, the study concludes that gas on a life cycle basis emits 36% to 47% less carbon than coal and 20% less carbon than heating oil. The study was done by ICF International.
And thanks to shale gas production, gas right now is available for bargain basement prices, reducing the energy expenditures of New Yorkers by about $1,500 per year, when compared to 2008 gas and wholesale electricity pricing.
Compared to coal and oil, gas provides more of NYC's energy, is cleaner, and today cheaper. All that makes New York City better economically and environmentally for all its residents and visitors.
