Social criticism gets more and more difficult, as the subject matter gets more and more unreal. Getting unreal is how criticism is evaded. The more unreal, the more impossible criticism becomes.
For this reason, social fantasies are going off the charts. A group of connected fantasies are being contrived around global warming, renewable energy, carbon free electric vehicles, self-driving vehicles and going to Mars.
To criticize such fantasies requires mowing down a lot of developed verbiage. Doing so is not allowed. All criticism must be superficial and trivial.
The problem is that the contrivers get by with it. Significant social criticism is not being allowed, while contrivers get more and more unreal.
The specific examples of how this works are very clear. Renewable energy is a contrived absurdity, as demonstrated in Europe, where Germany is building new coal plants, and England is building a new nuclear reactor, because their economies cannot survive more renewables. They have 25% renewables (15% solar and wind), while the price of their electricity is 8 to 10 times what it costs with coal.
Solar energy can never be relevant on a large scale for two major reasons. One: Solar will never be used on a significant scale outside southwestern US, where there is low overcast and bad weather. Two: Six hours per day of high intensity radiation (one fourth of the time) will never be significant. Backup systems gain almost nothing but more expense from solar disruption for six hours per day.
Increasing the time by turning with the sun increase the required surface area proportionately, while less light gets through the longer path through the atmosphere.
Wind power has similar problems. Wind can stop blowing for days at a time. A backup system of 100% is required. Having that system sit around unused is extremely wasteful. Wind changes so fast that backup systems need to be always on.
Transmission lines are required for wind and utility-scale solar. Transmission lines generally cost as much or more than the production costs for the energy, and they lose energy along the lines.
For short lines, a minimum of 20% loss is built in; for longer lines it is 50%. The reason is because there is resistance in the metal which creates heat as a loss of energy. To reduce the resistance by half requires twice as much metal. To reduce loss from 20% to 10% would require two lines instead of one. To reduce loss on long lines from 50% to 25% would require two long lines instead of one.
This is why there is a shortage of transmission lines in the US. The distances that must be covered are too large. It's a losing battle between energy loss and massive lines. It doesn't pay. Explanations of Energy Efficiency
The metals which make transmission lines expensive are refined with coke, which comes from coal.
Energy storage systems which convert to other forms of energy lose about 60% transforming in, and another 60% transforming back to electricity. Salvaging 40% of 40% is 16% recoverable.
Environmental damage and human disturbance are usually unacceptable for both solar and wind energy, even on a small scale. Scaling up would be prohibitive.
Solar and wind run into a barrier around 15% of electrical power, because electrical systems cannot tolerate more than 15% fluctuations, and backup systems are not perfect enough to remove fluctuations. No one can get past the 15% barrier with solar and wind combined beyond obfuscation over numbers and diversions.
The 36% wind energy in Iowa is not an exception. The lines are connected to a larger area which reduces the real average, while much of the energy goes into ethanol production. With only 5.6% of the electrical generation from natural gas, what does Iowa do when the wind stops? It shows that the wind energy which is used for normal electrical purposes is a small part of the surrounding systems which it is integrated intocertainly a lot less than 15%.
