One of the arguments people use against natural gas is that it could aggravate the greenhouse effect, and concerns about climate change might be holding back its mass consumption. Apparently methane is about twenty times worst than carbon dioxide once in the atmosphere, so leaks would be a problem.

However I don't really buy that argument. The problem is only with direct leaks, and I don't think gas leaks are any worst than oil tankers leaking into the ocean. Wind and solar energy are interesting alternatives to oil, but they will clearly never be able to supply more than a small fraction of our energy needs. Natural gas seems like a great solution right now. Probably we will need to see another bubble in oil prices and fears about consumption being greater than supply before we start using more gas.
