Hi,
It depends on the type of greenhouse you have the crop you are cultivating in it right now. If its a fully high cost greenhouse where you have humidifiers and sprinklers, fan and pad system, misting and a temperate crop or nursery inside. You will need electricity most of the time to keep temperature under control. If its a low cost or medium cost polyhouse electricity is not required on a conntinuous basis.
