Explanations of Energy Loss

 

About 70-90% of the energy in electricity is lost to heat—that is, while the system was designed for toasters. When fake renewables get relevant, 95% of energy will be lost to heat. Electricity Is The Problem

Transmission lines have a built-in loss for the purpose of reducing the number of lines. Long lines have 50% loss built in, and short lines 20%.

Electrical resistance in lines creates heat as lost energy. The smaller the wires, the more the resistance. Large wires have less resistance and less energy loss. But large wires are more expensive and take up more space. And diameter is not optional, as strength of the metal must define the size.

Two feet lose twice as much energy as one foot. So long lines lose more energy than short lines.

With overhead wires in transmission lines, the strength to weight ratio for the metal is important. This means there is an optimum size for the wires based upon the strength of the metal and how close together the towers are. If more energy must flow, additional lines have to be constructed, because the wire size cannot be changed from optimum.

Therefore, if the built-in loss for long transmission lines is reduced from 50% to 25%, the number of transmission lines would have to be doubled. Doubling the lines would be very expense and damaging to the environment.

If less energy is put through a line, there will be less loss. It's like a drop cord in a house. A lot of current will cause it to heat up. Less current through the same wire will lose less energy. Therefore, the operators can send less energy through a line, if they want less loss. But long lines are more expensive than the source of the electricity. So demanding lines are loaded down, which usually means operators will send through enough energy to result in 50% loss for long lines.

Higher voltage will push more energy through a line with less loss. But voltage is a given with limitations, which changes none of the rest of these concerns. The loss due to heat is proportional to the amperage.

Hot Wires

Wires Heating

Increased current through a wire causes the wire to heat and voltage to drop across the wire. With a 120 volt supply, there will be less voltage available due to wire loss.

Ohm's law says, volts equal amps times ohms. V=AR

An unnamed law says watts of energy equal volts times amps. W=VA

If then, 30 amps of current goes through a one ohm wire, the voltage across the wire is 30 volts, while the end use has only 90 volts available. The wire is like an electric heater which produces 900 watts of heat.
 
To reduce energy loss in a transmission line, the amperage would have to be reduced. But then, less energy flows through the line. So engineers pick a value for energy loss based upon how much metal someone wants to pay for.

For short lines they say, let's lose 20% of the energy in the line. For long lines, they say, we better lose 50% of the energy in the line, or someone will be paying for more metal than they can afford.

Resistance

(proportionalities, not real numbers)

Wasted energy as heat is proportional to the ohms of resistance. Fewer ohms requires more wire. Twice as much wire produces half as much heat.
 
Energy Lost Getting To Consumers

Electrical generators salvage a maximum of 40% of the energy that goes into them. Short transmission lines have 20% loss built in, long lines have 50%. High voltage transformers have 90% efficiency, household level transformers have 50% efficiency, medium level transformers would be 50-70% efficiency.

The result for long lines is 0.40 x 0.50 x 0.90 x 0.70 = 12.6% energy recovered, 87.4% lost.

For short lines: 0.40 x 0.80 x 0.90 x 0.70 = 20.2% energy recovered, 79.8% lost.

There is a lot of variation in systems, but most are worse than these figures, not better.

So-called renewable energy as wind and solar does not have the original 40% loss in the generator, but those sources waste a large amount of their energy in back-up systems and require longer lines, which again translates into about 90% loss before getting to consumers.

After getting to consumers, there are additional losses.

This extreme inefficiency due to energy lost to heat was tolerated in the past, because a little bit of electricity was needed for special purposes such as toasters and water heaters. Affluent persons used more electricity, while the lower classes skimped.

So incompetent persons such as greens assumed energy could be converted into electricity for transportation not knowing how wasteful electrical energy is. Then incompetent scientists and bureaucrats assumed electric motors were getting 96% efficiency, while it is 25% or less, and they led greens to assume electric vehicles are more efficient than gas powered vehicles, which is not true.
