I think that enough institutional and retail investors have foresworn oil and gas companies for non-economic reasons that they will have excess returns going forward. I intend to benefit from this -- one simple way is to invest in the XLE ETF. Since hydrocarbons make our comfortable modern lifestyles possible, I have no qualms in investing the companies that produce them. Studies have found that global warming may cause a loss of 5% of GDP by 2100. That is about 2-3 years normal economic growth and can easily be managed.
