1030-1060 BTU/cf 1 gal (US) = 0.133 cf (cubic foot) 1 cf = 7.48 gal converting units, 138 - 142 BTU/gal X 600 ( the approximate volume change from liquid to gas = 84,000 BTU/galhttp://www.retailenergy.com/hybrid/Liquified%20Natural%20Gas.htm The previous answer neglected to account for the difference in the BTU/vol of methane as a liquid vs the BTU/vol of methane as a gas
Many powders and solids can be melted (liquefied) by heat. For instance, sugar and butter is often melted in cooking.
A watt is a unit of power (Joules/second: energy / time). I guess it depends on what method you are using to get energy out of the water, as to how much energy is in it.
It would seem that for many people, the fact that an energy source is "natural" is not the only criterion to select an energy source.
Natural gas has many advantages but one of them is, It produces big amounts of energy, but lower levels of many air pollutants that coal or oil. One disadvantage of natural gas is that it is highly flammable. Hope I helped!

Liquefied petroleum gas has 49 megajoules of energy per kilogram.
97 cubic feet of natural gas will make 1 liquid gallon.
One gallon of kerosene will produce 134,000 BTUs of energy when burned.
Many powders and solids can be melted (liquefied) by heat. For instance, sugar and butter is often melted in cooking.
The energy content in fuels is often measured in BTU (British Thermal Units). I'm assuming that you're talking about compressed natural gas, as in the form that is used in some cars like the Honda Civic GX. One gallon of compressed natural gas contains 138,700 BTU. One gallon of gasoline contains 125,000 BTU. [http://www.bts.gov/publications/national_transportation_statistics/2002/html/table_04_06.html]
It comes from the suns energy
60% * 500 = 300three hundred gallons (of liquid - the gas before being liquefied - takes up MUCH more volume)

It will vary somewhat with the composition of the natural gas, but roughly 133 cubic ft of natural gas has the same heat value as 1 gallon of #2 heating oil. Minutes do not enter into the calculation
