One office building contains only incandescent lights The building next door contains only fluorescent lights Predict which building has higher energy bills Explain your answer?
The building with incandescent lights will likely have higher energy bills because incandescent lights are less energy-efficient than fluorescent lights. Fluorescent lights use less energy to produce the same amount of light, making them more cost-effective in the long run.
What kind of energy of energy does a night light use?
A night light typically uses electrical energy to power the light bulb or LED inside it. Some night lights may also use battery power, which can be rechargeable or disposable.

To reduce energy use and costs, it's best to unplug these devices when not in use.
Does photosythesis occur at night?
Photosynthesis requires energy from light. If there is no light there can be no photosynthesis. Photosynthesis doesn't occur in the dark. You could use electric lights to simulate daylight and make plants photosynthesise during the night time.
