Which of the following technologies would be improved by being made more efficient?Check all of the boxes that apply.

Efficiency means getting the same useful result while using fewer resources, or getting more useful output from the same resources. Longer-lasting batteries, cheaper-to-build wind turbines and solar panels, and crops needing less pesticide protection all improve resource use or reduce costs. Power plants that burn energy faster would use fuel more quickly, not necessarily produce energy more efficiently.
