No, it doesn't; it just has to cost less, overall. Efficiency is only a weak proxy for cost.

- clomond 5y ago*unless we are talking about energy systems and therefore VARIABLE costs matter significantly.
- mrpopo 5y agoNot if you want to consider environmental impact. The petrol in the ground is free, sunlight is free, biodiversity is free. The cost is only a human factor. Higher efficiency on the other hand usually means lower resource consumption.
- johnchristopher 5y agoWhy is that downvoted ? You might have the cheapest energy source, if it's not efficient enough to meet demand without ruining the environment for humans then it's not good. A weak proxy for cost ? Or a strong one for survival ? A cheaper steel bike is less efficient than an expensive carbon fiber bike when your goal is to get to the mountain top before the flood submerges the valley.
- wiz21c 5y agoAnd cost is sure not a proxy for efficiency.
