Re: “Comment period ends on controversial environmental assessment of hog farm near Buffalo River

Just a note in passing, Cargill sold their pork operations to JBS.

Re: “The messy Clean Line issue

"Isn't there enough solar energy in Tennessee, Alabama. Georgia & the rest of the TVA to power all of their energy needs?"

Of course not, or nobody could make a buck moving wind power there.

We need both widely distributed solar and concentrated wind to avoid extermination of a lot more than just Prairie chickens and bats. Unabated global warming is a impending disaster that must be addressed as quickly and broadly as possible.

Re: “Gov. Asa Hutchinson: Syrian refugees unwelcome in Arkansas

Hutchinson? Is that some kind of Scandinavian name? Aren't they socialists? I bet he is from an immigrant family. Next thing you know he'll have eating Lutefisk and listen to ABBA.

Re: “The messy Clean Line issue

Not to split hairs, but proper knowledge of the subject is important if for the sake of a rational argument. The average area needed for wind turbines is of the order of about 85 acres per megawatt, not 25.

I know details are a bitch, but when talking about energy they are important.

Look, I'm a big fan of solar, I am a net exporter of electrical energy from my PV array. But the capacity factor for solar is on the order of .2. Wind in the midwest is over .5. For solar to be useful it need more backing and or a massively larger gird (transmission lines) to get power from hither to yon.

And solar is difuse. Most single family homes in Ar consume over 1000 kWh/month. To power just one home would require about 1200 sq ft of unshaded south facing roof.

We need an array of sustainable energy sources and midwestern wind with the attendant transmission is part of our future.

Re: “The messy Clean Line issue

Problem bear, the project in NW Arkansas will NEVER come to fruition. It is a scam by a flim flam man. It is physically impossible. Here are the details: they propose to use an as yet unbuilt turbine with a cross sectional area of about 20 ft. They say that they can generate 1 megawatt in a 17 mph wind. At best they might get 5 kW, 1/200th of what they claim. they are using this to hustle money from investors. [ a little scientific knowledge goes a long way]

We (the AR Sierra Club ExComm) have discussed it but we haven't taken a position as it is an non-starter.

Re: “The messy Clean Line issue

Fossil fuel industries through their front groups are definitely anti-wind. If in fact expansion of the production and delivery of wind power caused an increase in carbon emissions from fossil fuels one would think they would be for wind expansion - they're not.…

Re: “The messy Clean Line issue

That's rich, I give you a link to a report by the National Renewable Energy Laboratory (NREL) and you counter with a link to wikipedia?

Within the confines of the study, wind can be dispatchable and thereby stabilize the grid. Midwestern wind is reaching 50%+ capacity factor or more currently and with the development of grid scale batteries will require no backup.

I find it telling that you condemn wind due to its intermittentcy, and counter with solar as a solution that is even more intermittent. And even solar will require transmission/distribution network to get power to those who don't have access to the sun. Not everybody lives in a single family home without any trees.

If the construction of the line really would cause an increase in carbon emissions, the coal industry would be supportive of wind - it is clearly not.

In conclusion , knock of the ad hominem stuff. Make your argument without saying what you think I know or what you think are the motives or knowledge base is for the Sierra Club.
