The Democrats’ Green New Deal calls for a fully renewable electric power grid. Regardless of the economic or political challenges of bringing this about, it is likely technologically impossible.
An electric power grid involves second-by-second balancing between generated supply and consumer demand. In the case of a sudden imbalance—such as from the loss of a generator’s output—all the remaining generators on the grid instantaneously pool together. Each one pitches in a small part of the required power to make up for the lost generator fast enough to keep supply and demand balanced.
This doesn’t work for wind and solar because you can’t spontaneously increase wind or sunshine. Hydro power is limited and unevenly distributed around the country. And for safety reasons, nuclear power—even if the Green New Dealers accepted it—can’t be cranked up to neutralize imbalances. Nor can consumer demand be suddenly reduced enough.
Fossil-fuel turbines, by contrast, very naturally compensate for sudden supply outages. The inertia of the spinning mass of rotors provides the extra energy needed to compensate for the loss for the first few seconds. (Wind-rotor inertia is too short-lived.) Meanwhile the generators’ on-line reserve capacity kicks in, giving a rapid boost in power output to prevent the turbines from slowing down. That substitute power, called “governor response,” lasts as long as 15 minutes. During that time a single replacement generator ramps up to compensate entirely for the loss. All the turbines on the grid are thereby restored to their original speed, and the governor response is rearmed for the next disturbance.
An all-renewables grid would require prohibitively expensive battery storage to compensate for sudden power losses. Even with batteries, the lost power would have to be fed through “inverters”

I think the Energizer Bunny knows more about the grid than Ocasio-Cortez.
It’s my understanding that the utilities have to take special measures to deal with these kinds of factors when the greenies sponsor their stupid “Earth Hour” in the Spring.
I learned all this in college from a visit to a coal fired plant.
People are generally clueless about where electricity comes from and how it works.
It just doesn’t suddenly appear in those little holes in your wall.
Minor problem. Candles and woodstoves.
Does her renewable energy ideas include extending Daylight Savings Time several more hours to gather more sunlight?
Perhaps huge electric fans blowing on the Wind Turbines during slack times.
Yeah, that’ll work!
Sandy Maduro Cortex.
I’ve been saying since day one of the Green New Deal that anyone pushing it is as clueless about thermodynamics as they are economics, and that implementation would take us back many decades in living standards - to the 1930s and the Great Depression.
The ants in my kitchen know more about the electric grid than the Cortez nimrod.
Next you'll be telling us there are no fairies.
The average Democrat voter actually thinks this. Years ago I had a conversation with a wind power person whom till this day I'm convinced was serious when he said that in times of low wind he could always run his windmills with fans.
I knew of a cat that found out more after it climbed through a bottom vent into a switchgear cabinet. Same with a rat that climbed into a meter base w/o out the cover.
I'll bet that the lesson didn't do the cat any good. I'm still betting on the ants as knowing more because they're still alive.
21 Feb: Reuters: U.S. judge dismisses boys’ lawsuit against Trump climate rollbacks
by Jonathan Stempel
A federal judge has dismissed a lawsuit by two Pennsylvania boys and an environmental group seeking to stop U.S. President Donald Trump from rolling back regulations addressing climate change, saying the court does not have power to tell the White House what to do.
Disagreeing with a judge overseeing a similar case in Oregon, U.S. District Judge Paul Diamond in Philadelphia ruled on Tuesday that the Constitution does not guarantee what the boys and the Clean Air Council called a due process right to a “life-sustaining climate system.” ...

Another example of the wisdom of children. I think that a large percentage of the Democrat base has the mentality and intellect of 10 year olds irrespective of their actual age.
The only renewable energy source are trees. You cut one down for fuel, you plant two more. Now if we could capture the methane from cow farts that might be a renewable fuel source. Cow eats grass, farts, cow eats more grass, farts again.

21 Feb: BBC: Climate change: Ban gas grid for new homes ‘in six years’
By Roger Harrabin
In cities, new housing estates and flats should be kept warm by networks of hot water, says the report.
The water could be heated by waste heat from industry.
An alternative approach is to use heat pumps, which draw warmth from the sea or lakes; or burn gas from waste.
The report, from the independent Committee on Climate Change, recommends these changes are made to new homes at first because it’s much more economical that way. They say it costs £4,800 to install low-carbon heating in a new home, but £26,300 in an existing house.
What’s more, these systems will only work if homes are insulated to the highest standards so they need little heating…
The chair of the Committee, Lord Deben, is being investigated by the Lords Standards Committee to see if he has breached rules by not declaring income from firms that benefit from pro-active climate policies. Lord Deben says he has followed advice on the rules.

20 Feb: GWPF: from WaPo: White House Readies Panel To Assess If Climate Change Poses A National Security Threat
The proposed Presidential Committee on Climate Security is being spearheaded by William Happer, a National Security Council senior director.
The White House is working to assemble a panel to assess whether climate change poses a national security threat, according to documents obtained by The Washington Post, a conclusion that federal intelligence agencies have affirmed several times since President Trump took office.
The proposed Presidential Committee on Climate Security, which would be established by executive order, is being spearheaded by William Happerr, a National Security Council senior director. Happer, an emeritus professor of physics at Princeton University, has said that carbon emissions linked to climate change should be viewed as an asset rather than a pollutant...

“Nor can consumer demand be suddenly reduced enough.”
He misses the point that one purpose of the ‘NGD’ is the reduction of consumer demand to levels that renewables can support.
For example, The ‘NGD’ will transform housing from suburban separate family to high rise condos of limited size.
“It’s my understanding that the utilities have to take special measures to deal with these kinds of factors when the greenies sponsor their stupid “Earth Hour” in the Spring.”
I had no idea that FReepers who claim to turn on all their lights during “earth hour” were actually performing a useful public service!
