Natural gas, the overlooked alternative to oil

Natural gas reserves

Total - 135,119,592,390,000 cubic feet (source)

Natural gas consumption

Total - 1,482,830,070,000 cubic feet (source)

If we continue to use natural gas at the same rate
as we use it today, the United States has about a
50-year supply of natural gas, though another 200
years of additional gas supplies could be produced
if people are willing to pay more for the gas
they use.

Compared with oil at more than US$60 a barrel,
an energy-equivalent amount of gas costs in the
region of only $20. Experts predict that gas,
which was once considered a wasteful by-product
of oil exploration, will turn into the No 1
fossil fuel. Vying for gas resources are the
world's top guzzlers of energy, the United
States, Europe, China and India.

Propane conversions should give the planet some
breathing room while looking for the ultimate
energy source.
