I have this question for some time, I am not too sure current price of natural gas between North American and European. By the way, why do they use cubic meter instead mmbtu? This is very confusing to figure out the difference between prices. 1 NG contract = 10,000 mmBtu = 27,777.78 cubic meter (I use 1 cubic meter = 36,000 Btu) if Russian is selling $235 per 1000 cubic meter to some country, which makes 1 NG contract only cost $6527.78 ( 27,777.78 / 1000 x 235). and even if Russian is selling $480 per 1000 cubic meter to Germany, which is making like 1 NG contract only worth about $13,333. Why Russian gas is much cheaper than North American? or did I get my number wrong somewhere?
