Shorting the Grid: The hidden fragility of our power grid

 If you are video oriented to the link which is a review of the documentary "Juice", it contains links to the excellent documentary.

I'll make the obvious points that people have been so brainwashed they forget: 

  • The sun only shines by day, and sometimes it is cloudy.
  • To produce solid power, wind turbines need winds of 12-25 MPH to be efficient producers, at around 55 MPH, they have to set blades to protect themselves from damage and can produce no power. (blizzards in cold climates often exceed that when the power is needed most)
  • We need constant, cheap, reliable power to operate our society. Renewables miss all three. 
  • Since renewables are unreliable, they must be backed up with instantly available power. Translation, every watt of "green" energy has to be backed up by coal, natural gas or nuclear. No current or foreseeable battery backup is useful for grid level energy.
The preferred backup is Natural Gas (NG). Unfortunately, building new pipelines has been blocked because environmentalists want ZERO use of fossil fuel, When the weather gets cold, the demand for NG goes up enough that power plants can't get it. 

One of the most efficient power plants on earth is a Combined Cycle Gas Turbine (CCGT). When you run such a machine steadily in baseload operation, it can turn about 60% of the energy in the gas into electric energy. In contrast, a simple gas turbine will turn about 40% of the energy in the fuel into electricity.

That is great news (although still not good enough for the Greens that want ZERO emissions). However, given that current incentives are forcing wind/solar backed up with NG (the book explains how subsidies create this problem). 

Something you will likely not hear in mass media is: 

Emissions can also increase with the increased use of renewables. Backing up renewables can cause inefficient operation of fossil plants, leading to an increase of emissions on the grid. In other words, as renewables increase, emissions can also increase.

 To get the 60% efficiency of a CCGT, it has to be HOT. The efficiency comes from the exhaust heating a boiler for a steam generator. This is even worse for coal. The plant has to be run at a lower (inefficient) output to do a "hot switch" when its power is required, 

Much of the time, a "green grid" is dirtier than a scrubbed coal CCGT powered grid, because since the renewables are not stable, the scenario can be likened to you driving your car between being shut off, and then mashing the gas to the floor to go to maximum speed, your mileage will vary (down), and your emissions will increase, 

Why are the rich and powerful so excited about wind? Here is Warren Buffet on the issue: 

"I will do anything that is basically covered by the law to reduce Berkshire’s tax rate,” Buffet told an audience in Omaha, Nebraska, recently. “For example, on wind energy, we get a tax credit if we build a lot of wind farms. That’s the only reason to build them. They don’t make sense without the tax credit.”

The rich get richer from tax credits, while the poor get poorer from higher energy costs. As the grid becomes increasingly fragile, the poor also get to live and die in cold darkness. 

The obvious answer to this is nuclear, and if any of the supposed "greens" in power actually believed that Climate Change was a near term "crisis", they would be pushing building nuclear power in a way that would make them at least as much money as the current "renewable" wealth generator for the billionaires. 

Our elites care about their wealth and false "virtue". The fact that the collateral damage is high energy prices that the middle and lower classes can't bear and rolling blackouts or worse for the "deplorables" is not a concern for the Davos folks. 

They know all this; they just want to make sure you don't!
