Quick Facts

Quick Global Warming Facts


The following contain rough, rule of thumb approximations as of 2018.


Natural gas saves 45% in CO2 emissions over coal per BTU.
Natural gas saves 25% in CO2 emissions over petroleum per BTU.

1 kwh = 3412 BTUs
1 quad = 29.3 gWh


U.S. Emissions

Emissions from fossil fuels = 5,000 MMTs  (million metric tons)

Fossil Fuels in the U.S.

Coal
13.3 Quads consumed
Converting to Nat. Gas:  Saves 10% of emissions

Petroleum
36.9 Quads consumed
Converting to Nat. Gas:  Saves 12% of emissions

Natural Gas (NG)
31 Quads consumed
Increase roughly matches coal decline


Energy used in the U.S.

32,700,000,000.000,000 BTUs / yr used  (32.7 Quads)
68,500,000,000,000,000 BTUs / yr wasted
101,200,000,000,000,000 BTUs / yr consumed  (101.2 Quads)

81.2 Quads of fossil fuels consumed
(16% from coal, 45% from petroleum)
Using NG instead of coal saves 


Electricity
12,900,000,000,000 BTUs / yr  generated in electricity
4,400,000,000,000 kWh / yr  generated
3,950,000,000,000 kWh / yr of electricity used
10% generated power wasted
Consumes 90% of coal
Consumes 35% of natural gas
National average electricity :  1.18  GHG/kWh


Transportation
Requires 6 Quads/yr = 2,000,000,000,000 kWh generated / yr
Uses 70% of petroleum consumed
Consumes 20% of all energy used

Gasoline  1 gal = 33.41 kWh


Gas car             23.4  mi/gal  (2016 avg)  11,824 mi/yr
Hybrid car         44.4
EV                   104 mi/gal eq  = 0.32  kWhr/mi




Industry
Consumes 25% of petroleum
Consumes 35% of natural gas
Consumes 10% of coal
Consumes 25% of electricity
Consumes 40% of all energy used
