> [@Stranger\_On\_A\_Train](#): > > There will always remain deposits of ‘fossil fuels’ (and we have many decades of known natural gas reserves that could be extracted at a sufficiently high marginal cost) but when the energy cost of extracting the fuel exceeds what it can actually provide, the only reason to justify it is to maintain the existing infrastructure by subsidizing extraction through using other sources of energy, and in fact that is already happening for offshore oil, where wave energy [is being used to extract oil and gas](https://www.netzerotc.com/case-studies/harnessing-wave-energy-to-produce-power-for-oil-and-gas-installations/) which really isn’t cost effective otherwise. An argument of “we’ll stop extracting fossil fuels when it costs more energy than we’re getting from it” is not, in fact, reinforced by an example of us continuing to extract fossil fuels even when it costs more energy than we’re getting from it. --- _[View the full topic](https://boards.straightdope.com/t/global-warming/1024461)._
