Understanding Power, Energy, and Efficiency in Electric Circuits
Power efficiency is typically measured as a ratio or percentage of output power to input power. It''s calculated using the formula: Efficiency = (Output Power / Input Power) × 100%. For example, if a motor draws 1000 watts of electrical power and produces 850 watts of mechanical power, its efficiency would be (850 / 1000) × 100% = 85%.
If efficiency were the only thing that mattered, a 100% shift to battery-powered vehicles and power generation would be called for with few questions asked. But, as already noted, decisions around energy procurement and production entail many additional factors and batteries do not make sense in all use cases.
