Turn off the lights as you move from room to room. Install thermal motion sensors that will turn off the lights for you.
Use local lighting: spotlights, floor lamps, sconces. For example, in order not to turn on the main light sources every time, it is better to install LED strip lighting in the room.
Remember that cleanliness is the key to saving money. Dirty windows and dusty ceiling lights reduce the level of illumination in the room by up to 35%.
When repairing, keep in mind that light walls and furniture will reflect up to 80% of the luminous flux, and dark ones — only about 12%.
Replace incandescent bulbs with energy-saving and LED ones. Replacing only one lamp will save about 1,000 rubles a year.

For example, let's take Moscow — let's assume that 1 kWh in the capital costs 5.38 rubles. Imagine that three light bulbs are lit in three apartments for eight hours a day: LED, energy-saving and incandescent. For a more objective picture, we will choose lamps of such power that they give approximately the same level of illumination. And that's what we'll get.

Lamp type	LED	Energy-saving	Incandescent
Power consumption, kW	0,013	0,025	0,1
Lamp life, hours	50 000	8 000	1 000
Lamp cost, rub.	248	200	11
Cost per hour of operation Cost per hour of operation = tariff × power + lamp cost ⁄ resource , rub.	0,0749	0,1595	0,549
Hourly savings Hourly savings = incandescent lamp operating cost − the cost of operating the lamp being compared , rub.	0,4741	0,3895	—
Payback period Payback period in hours = (lamp cost − incandescent lamp cost) ⁄ hourly savings , hours	499,89	485,24	—
Payback period Payback period in days = payback period in hours ⁄ 8 , days	62,49	60,65	—
Annual savings Annual savings = (8 × 365 − payback period in hours) × hourly savings , rub.	1147,37	948,34	—

It turns out that in two months one energy—saving lamp will allow you to save 40 kopecks hourly, and 10 bulbs - 4 rubles.

Use electrical appliances correctly

In the absence of a two—tariff electricity meter, turn off all non-basic electrical appliances overnight, and chargers - after the equipment is fully recharged.
The refrigerator must be defrosted regularly if it does not have a special No Frost system. Make sure that the device is as far away from the heating appliances as possible and natural ventilation of the rear wall is provided. Put only the cooled dishes in it!
Monitor the performance of the burners of the electric stove and put only the right-sized dishes with a flat bottom on them.
Cover pots and pans with lids: they reduce heat loss by almost three times.
Try not to overload the washing machine (excessive loading increases electricity consumption by up to 10%) and use an average temperature regime. Washing at 30 degrees consumes 35% less energy than washing at 40 degrees.
Use an electric kettle instead of an electric stove to heat up the water. It will be much more economical this way. Boil only the volume of liquid that is needed at the moment.
Regularly clean the fans and filters of the air conditioner.
Things that require a low temperature regime, iron after turning off the iron.
Do not leave appliances, including microwaves, televisions, computers, scanners, printers, modems, in standby mode. This will save more than 200 kW per year.
Use electrical outlets with a timer.

Buy energy-saving household appliances

All electrical appliances are marked with Latin letters from A+++ to G. Choose equipment with a low energy consumption class, labeled A and B.
Buy appliances that use the latest energy-saving technologies. For example, induction cooktops are becoming increasingly popular, heating only the bottom of the dishes and not wasting energy. The efficiency of such plates reaches 95%!

Install a two-tariff counter

A two-tariff meter allows you to save at night. Such meters are beneficial to those who can use energy—intensive household appliances: a dishwasher and washing machine, a bread maker - from 23.00 to 7.00. On average, the meter pays for itself in a year.

Don't waste heat

Instead of a traditional heater, use an air conditioner configured for heating mode. If the manufacturer allows it, of course. Many air conditioners cannot be used at subzero temperatures.
The infrared heater is more economical than the others by 30-80%.
If electric batteries are installed in the house, try to keep them clean so that the dust does not absorb some of the heat, and you do not have to increase the temperature regime.
Using a water heater, reduce the water heating temperature.
Replace the storage water heater with a flow-through one. This way you will not waste electricity on constantly maintaining a certain water temperature.
Heat the water only if necessary. Disconnect the boiler from the mains when you leave home and at night.
Once every three months, clean the water heater from scale, which increases electricity consumption by 15-20%.
- Disconnect the device from the mains and turn off the water supply.
- Drain the water completely.
- Remove the boiler cover, carefully disconnect the wires and unscrew the thermal relay.
- Unscrew the nuts holding the flange. Push the flange up, turn it and pull it out.
- Now you can clean the heating element with a metal brush. A solution of acetic acid and hot water (1 : 5) will also help to get rid of plaque. Just put the heater in it for 30 minutes and make sure that the sealing rubber does not come into contact with acid.
