GE's bet on natural gas, renewable energy pays off

This attempt for power generation efficiency is a wager on the estimate of long term availability of low cost natural gas. Unfortunately it is a losing bet for fighting climate change that even Obama now is willing to take. The sources of the natural gas are shown to have environmental issues in addition to the carbon from burning the fuel. From the GE corporate perspective it will provide profits supplying technology to an international market. The higher the profits the less likely needed efforts will be made to reduce carbon, only reduce the rate of production. And that is not likely to be as much as suggested as world power loads are increasing.

However it's going to take a couple of decades at least to build out the renewable energy infrastructure and in the mean time natural gas is a better alternative than coal.
