Of course, something silly is your only answer. Typical MAGAt.

My response is just geared to the dipshit I'm talking to.

Coal-fired power plants typically operate at 32–35% efficiency, with modern supercritical and ultra-supercritical plants reaching up to 45–48%.

Typical​

Traditional coal-fired power plants convert the chemical energy in coal into electricity through a series of energy transformations: chemical → thermal → mechanical → electrical energy. Most conventional plants operate at 32–35% efficiency, meaning that roughly two-thirds of the energy in coal is lost as heat during the process.

Advanced​

Efficiency improves significantly with supercritical and ultra-supercritical technologies. Supercritical plants operate at higher steam pressures (around 220 bar) and temperatures (600/600 °C), achieving efficiencies of up to 42%, while ultra-supercritical plants can reach 45–48% efficiency due to even higher operating pressures and temperatures. Integrated Gasification Combined Cycle (IGCC) plants, which convert coal into syngas and use combined cycle generation, can also achieve higher efficiency, though at greater cost.

Factors​

Several factors influence coal plant efficiency:

• Steam temperature and pressure: Higher superheat and reheat temperatures improve thermal efficiency.

• Coal quality: High-calorific-value coal with low ash and sulfur content enhances energy output and reduces residue buildup.
  
  1
• Maintenance and operation: Regular inspections, servicing, and predictive maintenance help maintain optimal performance.

• Emission controls: Installing scrubbers, electrostatic precipitators, and selective catalytic reduction systems can slightly reduce efficiency but are necessary for regulatory compliance.

Practical​

While coal plants are less efficient than modern natural gas combined cycle plants (up to 60% efficiency), they remain a significant source of electricity worldwide. Efficiency improvements not only reduce fuel consumption and operational costs but also lower greenhouse gas emissions per unit of electricity generated.

In summary, coal-fired power plant efficiency ranges from 32% in conventional plants to nearly 48% in ultra-supercritical designs, with performance influenced by technology, fuel quality, and operational practices.

I agree, the iron-water batteries have very low efficiency.

And all that charging electricity is electricity that would not be generated otherwise. But go ahead, demonstrate your love for high electrical bills from gas, coal, and nuclear generation.

Right, your expensive, intermittent "green" power sources generate very expensive power that wouldn't otherwise be generated.
At a high cost.
On the positive side, they'll lose half their power charging up your brilliant iron-water batteries.
