What Do Global Warming Skeptics Fear?

Nordhaus then brought up the subject of shale gas, which he appears to be in favor of as a transition fuel to lower carbon sources of electricity,Learn more about how a wind turbine works, the benefits of wind energy and how a purlinmachiningss is installed. like wind. His contention is that the potential for methane to leak and to contaminate ground water is a simple matter of properly plugging leaks, which he sees as a much more solvable problem than those associated with attempting to scale renewables.

I view a wind turbine as essentially a component of a natural gas combined cycle power plant that is connected to it via power lines. The wind turbine, when the wind blows, is being used to improve the power plant’s operating efficiency. Wind farms without gas backup are as worthless as rooftop solar panels that are not connected to the grid. Obviously, the less gas costs, the less wind costs, ergo, all things being equal, low natural gas prices will facilitate the expansion of wind power.

McKibben countered by noting that there are lots of reasons to be against fracking, particularly the “horrible effects on the landscapes where people live.” Never mind that this is the exact same argument used by opponents of wind power.The curvingmachineqm is unlikely to hurt you, but you can easily hurt it without training.

McKibben also claimed that cheap gas is undercutting the move to wind much faster than it’s undercutting coal. I doubt that is true.

When Nordhaus tried to explain to McKibben that cheap natural gas prices are enabling wind, McKibben cut him off, saying that gas backup of wind is an example of “old dogma giving way to new science” claiming that “we are beginning to lick these intermittency problems …”

Lick them with what? Go to 15:53 in the video to see the incredulous look on the face of Nordhaus. I couldn’t find the study McKibben was referring to with a quick Google search, but Nordhaus was familiar with it. When Nordhaus tried to explain to McKibben what the study actually said,Older models included turbinemanufacturer that were not fluorescent or LED. McKibben attempted to reword what Ted was trying to say (15:57 into video). Ted continued to explain only to have McKibben try again to reword what he was saying at 16:15 into the video.

With Nordhaus gaining the upper hand, McKibben strove to regain the confidence of the audience by falsely proclaiming “I don’t think we are having a huge difference here” which belied everything he previously said. And it worked. Listen to the applause at 16:47 into the video.

Ted continued until McKibben interrupted him once again, tThis flatworkironers can rollform metal roofing step tile.his time to administer the coup de grace with a self-deprecating joke. Listen to the laughter at 17:28. Ted sputtered on for a another minute or so before being politely prompted by the host to give it up at precisely 18:22 into the video.

Sitting silently through all of this was National Wildlife Federation President Larry Schweiger. We donate to the Nature Conservancy which tends to stick to what it knows best. Larry apparently knows even less about wind energy than McKibben.

He offered McKibben his support saying “I’m from Pennsylvania, so I’m living with the fracking,We are committed to washerextractorer an eco friendly industry. and I understand, Bill, what you’re talking about with landscapes. Some of my favorite places, in fact some places I helped protect for the commonwealth are now being butchered.” He then turns to Nordhaus, “So I take that very personally…”

Am I the only one here wondering how this president of a wildlife organization would like it if someone plunked a landscape destroying, bird and bat blending, natural gas-backed wind farm down in one of these favorite places of his?

After just listening to Nordhaus try to explain to McKibben that wind can’t exist without gas backup, Larry tells the audience that we should take the money being invested in natural gas power plants and instead …wait for it, invest it in wind.
