Saving electricity is extremely important primarily from the perspective of environmental protection. Keep in mind that you’re one out of hundreds of thousands of people who need electricityelectricityelectricity. Therefore, it’s necessary to ensure that there’s enough electricity for everyone. When you save electricity, there’s no need to generate it in increasingly larger volumes, thus leading to lesser pollution of our environment. Lower power consumption leads to lower electricity bills, which means that you’re saving both money and electricity. There are many ways to save electricity. For instance, you can use energy‑saving light bulbs. You also should unplug your devices, so that they don’t remain in idle mode and take proper care of your household appliances.

Energy‑efficient use of electrical devices
Important!

It’s worth to use energy‑saving light bulbs wherever they are on for many hours. If the source of light is turned on and off frequently (e.g. in the bathroom), an energy‑saving light bulb may become worn down before it pays for itself.
