“Does her renewable energy ideas include extending Daylight Savings Time several more hours to gather more sunlight?”
good idea ... my tomato plants could benefit from the extra hours of sunlight as well ...
“Next you’ll be telling us there are no fairies.”
As you become more technically adept you stop believing in faries, but start wondering if gremlins exist.
On another thread someone used the term “weather dependent energy”, that pretty well sums up wind and solar.
They want to base our power grid on it, makes no sense at all.
You’re being completely unreasonable.
You are expecting people who have no sense at all to make sense!
I haven’t looked into the GND at any depth but I do remember seeing something about the elimiation of fossil fuels. The next paragraph was saying something about building infrastructure, such as roads, bridges, airports, etc.
If you eliminate the fossil fuels, you don’t need that infrastructure, because nobody is going any farther than they can walk or ride a bike (or maybe ride a horse or a dogsled). At least until they starve to death since no food can be transported.
You're absolutely right. Power generation is a complex industry. At any given time the linked section of the grid is generating close* to exactly what the consumers are using. this is done by using hydro and nuclear as base load generation, coal as medium term throttle generation and using combustion turbines as quick ramp up generation. Even throttling fossil has drawbacks because when you throttle a generator you change the heat pattern in the turbine section and this puts stress on the blades and the shaft. Remember that these turbines have to turn exactly at 3600 RPM to keep the 18,000 volt 60 cycle AC 3 phase output in sync with the rest of the grid. if you have a sudden increase or decrease in demand the amount of steam (and hence energy) flowing to the turbine has to change too which is why the heat pattern changes when you throttle even though the generators are spinning at the same speed.
Now suppose Kongress has enough fools who think they can repeal the laws of thermodynamics to inflict the immense expense of converting a significant portion of the grid to solar. And cloudy weather such as we've had in Ga for the last month repeatedly moves in across your solar arrays. the backup coal systems have to throttle up (and you don't do this from a cold start - it takes 24 hours or more to cold start a big generator) your fossil/coal plants are going to stress their 8 figure turbines repeatedly and sooner rather than later they're going to fail - hopefully not catastrophically
*It would be exact except there are capacitors in the system to balance out the inductive load to keep the voltage/amperage phase relationship from going to far out and they have a tiny bit of storage capacity.
Base load is the minimum level of electricity demand required over a period of 24 hours. It is needed to provide power to components that keep running at all times (also referred as continuous load).
Peak load is the time of high demand. These peaking demands are often for only shorter durations. A Peak Load system needs to generate electricity almost instantly.
So what is the 'Green Energy' plan to prove a reliable, low cost Base Load Generator?
And what is the 'Green Energy' plan to prove a reliable, instantaneously Peak Load Generator?
Currently none of the 'Green Energy' proposals fit the needs for either generation system.
We dream the impossible dream...
Up your @$$ we intend it to ream...
Could we collect the farts and hot air from liberals?
The liberals would have to be imprisoned to allow collection of this new green source of energy. If I contact AOC, she will most likely want to imprison conservatives instead. But conservatives have significantly less hot air compared to liberals which significantly reduce the amount of energy gained! /sarc
I think you are giving them too much credit. After all, the plastic straw ban is based off a “research” paper written by a 9-year old. This is not a joke.
Missing from the Green New Deal is how food will be produced without internal combustion powered farm machinery to plant, harvest and transport agricultural products to market. Reverting to the horse or oxen powered agriculture of 150 years ago has a problem...these critters like cows are flatulent. I doubt AOC has ever seen a farm.
Excellent article, based on real science.
There’s a joke in there..
What did socialists and greenies use before candles and woodstoves?
Electricity.
It works exactly the same as an air conditioner (an air conditioner is a heat pump)except the cold side is on the outside and the hot side on the inside.
It’s spelled “Rolling Blackout.”
A heat pump uses energy to reverse local entropy. The heat is in the air/water. I remember for water its one calorie to raise 1 gm of water 1deg C. So if you have a kilogram of water at 40C you have 40,000 calories of heat (energy) that you can extract before the water freezes at zero C. If you use a heat pump to get that energy from that kg and transfer it to half a kg of water then theoretically you could get that half kg to 80 degrees. Of course there are losses and inefficiencies, but concentrating the energy via a heat pump uses less energy than just heating the half kg with your energy source. This only works well when youre not trying to heat pump between extremes. About 20C is about the best you can do in reality and still come out ahead. Thats why heat pumps work ok in FL TX AZ etc., but not in MI MA Y etc.
