Jevons Paradox tells us that embracing fracking to reduce coal emissions isn't enough, because any gains in lowering emissions will be offset by people burning more oil. There's a lot of underserved demand for energy, so gradual increases in efficiency (or, in this case, per-watt emissions) do not actually reduce total consumption.

Unless your plan to reduce emissions by embracing fracking comes with laws to restrict consumption - like, the kind of laws you'd have the villain in an Ayn Rand novel pass - then all you will do is increase emissions.

Of course, deliberately enforcing energy poverty is a bad idea and most[0] environmentalists aren't in favor of it. The reason why activists push renewables so hard is because the externalities on those are way better. i.e. pollution will not 'catch up' on solar and wind nearly as quickly, if at all, because solar panels don't emit anything when you're harvesting energy with them.

Also, solar is really, really cheap. It's pretty hard to argue against an energy source that gives you energy too cheap to meter, even if it's only during the day.
