How to Determine Energy Consumption

How to Determine Energy Consumption
Many factors affect electricity consumption. Most of the energy is usually spent on the operation of lighting fixtures, so it is better to start measures to reduce the consumption of electricity in this category.
Instructions
Step 1
It is enough to use the following formula to determine power consumption: W = P t T, where: W - kWh power consumption; P is the power consumed in kW by the electric receiver (electrical storage); t is the number of hours per day of work electric receiver; T is the number of working days of the power receiver.
Step 2
In turn, the power consumption is calculated according to the following formula: P = Ptot · K, where: Ptot - total installed power; K - demand coefficient. The value of the coefficient is obtained on the basis of the number of electricity consumers, the volume of load. It can be found in the directory.
Step 3
Thus, we can conclude that two factors directly affect the amount of electricity consumed: the power of the device and the time of its use. For consumers, electricity is not only an economic necessity, but also a commodity that can be saved and should be saved. Not only will this help save money for other needs, but it will also be more or less - it will save the planet from being depleted of resources. In fact, in order for a power plant to generate electricity, you need to burn a certain amount of fuel or firewood.
Step 4
Unfortunately, it is very difficult to calculate household electricity consumption with great accuracy on its own, as some devices have different functions, during which different energy is consumed. For example, the cycle of a washing machine includes pumping water, heating it, washing, drying, and so on. Therefore, the numbers are approximate. To achieve a certain accuracy, automatic electricity metering systems, in other words, meters are used.
Step 5
The most energy-intensive home appliance is, of course, the refrigerator. It usually runs all day and consumes at least 30 percent of all electricity. A simpler washing machine, vacuum cleaner, iron, etc. compared to it. When buying a new electrical appliance, you need to know immediately how much power it is consuming. In general, the more complex the technique, the more it consumes. Technical devices for customer management are divided into energy efficiency classes: A, B, C, D, E, F and G. The most economical equipment belongs to classes A, B and C.
Step 6
Often consumers use appliances sparingly, but forget about another energy-absorbing medium - the light bulb. You should not leave light where it is not needed and it is better to replace the lamps with energy-saving lamps. They are more expensive than usual, but their durability covers energy costs.
