It is true that energy with our current technology cannot be produced with absolutely zero emission, and so we must seek ways to minimize the effects on the environment to a sustainable level.
The degree of environmental damage varies depending on the method being used, but most of them involve carbon emission that contribute to climate change over a long period of time. The business involved all have some sort of regulations in place effective or not, and with public acknowledgement they have to be conscious of what they do, unlike fracking. (you don't see power plants dumping nuclear waste out in the open, they do it behind the scenes)
The problem with fracking is that they literally pump millions of gallons of water mixed with hazardous chemicals underground, and if you pump water underground, there's no way you'll be recovering 100% of it back. So where does all the unrecoverable used water go? They flow to the underground streams and come back up through evaporation, rivers, plant life, and wells.
A shocking thing that you will see in the film is what they do with the recovered part of the used water, they unload them in "pits" and use sprinklers to spread them into the air as smaller particles to make them evaporate faster. It's also very disturbing that this not only adds damage to the air, but those vapors could potentially be carried by the wind, spreading to other areas where people live.
Solar panels and wind turbines are long term investments, while they are costly and are not zero emission, they can reduce the overall level of carbon emission in the future. They are also not the only alternative "sustainable" energy out there, there are others that we can tap into with further technological advancement. Such as lightning harvesting/emulating and revamping the methods to harness heat from nuclear reactions.
I'm not trying to say that natural gas is should not be considered as an alternative energy source, it's just that the current methods being used cause so much damage that it needs to be stopped. The problem now is that a lot of people in the U.S. does not even know these details due to low publicity and misleading information from companies.
Unless more people educate themselves of the dangers of hydraulic fracturing, there won't be a big enough force to make companies to rethink their actions.
