Overall Efficiency | EGEE 102: Energy Conservation and …

So that means the overall efficiency is 1.5 divided by 100. Both are BTUs here. So the overall efficiency is only 1.5%. That is pathetically low. Which means to use 1.5 units of light, we are taking from Mother Earth 100 units. And along the way, we are dumping about 98.5 units of energy during various steps of conversion processes, and we''re ...

1.5: Power, Energy and Efficiency

Generally speaking, the higher the efficiency, the better. This implies less waste. In other words, if a system is 30% efficient, then 70% of the input power is wasted, whereas if a system is 99% efficient, then only 1% of the input power is wasted. The concept is
