If hybrid wind/gas electric grids work, if they are profitable, more will be built and the overall consumption of natural gas will increase.
There are billions of people on this planet who haven't yet been invited to participate in the affluent high energy industrial consumer economy.
As an affluent person it's immoral to say I get to burn the gas, but you don't.
My own electricity comes from Pacific Gas and Electric. PG&E's greenhouse gas emissions are in the low range for the industrial world. Yeah, 24% is nuclear.
Furthermore, PG&E rates our household a "smile" emoji 
for energy efficiency, that in spite of the 24/7 pumps of our water garden. (The water for these gardens is waste from our reverse osmosis system... we are totally first world affluent in some ways. I like to watch birds and fish. Occasionally birds eat the fish, but more often it's raccoons.) I guess the LED lighting and my disdain for central heating and cooling make up for the energy used by the pumps. But I'll never convince my wife we could live without the refrigerator, even though I've lived without one for long periods myself, as a kid and young adult.
Another way of reducing one's environmental footprint is to avoid meat, but we're total hypocrites about that because we have animal shelter rescue dog family and don't expect them to be vegetarians.
