Does turning off the lights really save energy?

Energy saving is certain, but it doesn't necessarily have any effect, because there are too many electrical appliances used in our daily life, and if we talk about energy consumption, lights are only a small part of it.

The reason why the lamp lights up is based on the loss of current, which is the utilization of energy. If the lamp is not on, it can naturally be made to glow with less electricity, which can naturally save energy. However, because the lamps used in our daily life are not the kind of products with particularly high energy consumption, turning off the lights casually, although it has the effect of energy saving, is also minimal.

However, there is a saying that flies are small pieces of meat, which may be a bit disgusting, but the truth is correct. If we turn off the lights 1000 times to save one degree of electricity, then the number of times people need to turn off the lights in this life is far from being calculated in thousands. So if you form a habit and accumulate it over time, it will naturally help to save energy.

If you really save energy, there are many other ways besides turning off the lights. For example, electric water heaters used at home, the average family may also use hot water at night. For office workers, if the water heater burns all day, repeated heating will inevitably lead to a waste of energy, so it is also energy-saving to turn off the water heater when not in use.

When working in the unit, turning off the computer, printer and copier after work every day is more energy-saving than standby power consumption for one night.

Energy saving should be an idea, not necessarily called energy saving. Washing hands with a washbasin is better than washing hands with tap water. Saving water is as energy-saving as saving electricity. So if you want, life is full of small details that can save energy.
