Advice 1: How to determine the power consumption

Consumption of electricity is affected by many factors. Most energy is usually spent on lighting, so measures to reduce the expenditure of electricity it is better to start in this category.
How to determine the power consumption
To determine the consumption of electricity, it is sufficient to use the formula:W = P·t·T where:W – the consumption of electricity in kWh;P is the power consumed by the power consumers (the electric device) in kW;t – time end user on the day in hours;T – number of days of operation of the end user.
In turn, the power consumption is calculated by the formula:P = robs·K, where:robs – total installed capacity;K is the factor of demand. The value of the coefficient will be based on the number of consumers, volume of download. It can be taken from reference material.
So, we can conclude that the consumption of electricity is directly affected by two factors: the capacity of the device and time of use. For consumers of electricity is not only an economic necessity but also a product which can and should save. This will not only help to save money for other needs, but neither more nor less – to save the planet from destruction of resources. After all, to power station generated electricity, we must burn certain amount of fuel or wood.
Unfortunately, to calculate self-consumption of household electricity with great precision is very difficult, because some devices have different functions during which they consume different amount of energy. For example, the work cycle of the washing machine includes a set of water, heat, washing, drying etc. So the figures are approximate. In order to achieve a certain precision, the use of automatic calculation system of electricity, to put it simply, counters.
Energopotreblenii appliance is, of course, a refrigerator. It usually runs for days and consumes at least 30% of all electricity. More modest in comparison with him are washing machine, vacuum cleaner, iron, etc. when Buying a new electrical appliance, you should immediately see its power consumption. Typically, the "tricked" technique, the more it consumes. To inform buyers of technical equipment are divided into classes of energy efficiency: A, B, C, D, E, F and G. the Most economical technique belongs to class A, B and C.
Often consumers efficient use of appliances, but forget about the other absorber of electricity – light bulb. Do not leave the light where it is not needed, and the light bulb is the best replacement for energy saving. They are much more expensive than usual, but its durability will pay for energy costs.

Advice 2: What is the power consumption PC

Electricity consumption is one of the most important settings that you should pay attention to when choosing and buying a personal computer. It depends on the computer capacity and the load on it.
What is the power consumption PC
The power consumption PC is directly connected with the power components included in the PC, as well as the degree of congestion of different software. Thus it turns out that, for example, if you buy a powerful power supply, it will consume much more electricity. It is worth remembering that the more processes will be running on the computer, the more will be consumed in the power supply, respectively, and electricity will be consumed much more. Much more importance is the purpose of running processes, that is, if you just work in the browser, the electricity will be consumed much less, and if you play games or work with demanding graphics applications, then more. The result is that all three of these factors (power supply, number and complexity of processes) directly affect the energy consumption.

Electricity consumption by the computer

Standard office system unit with operating office applications mainly consumes from 250 to 350 watts per hour. A more powerful computer that is running graphics applications and games, respectively, will consume more electricity, for an average of 450 watts per hour. Do not forget about the input devices and output information, which also consume electricity. Modern monitors today use 60 to 100 watt/hour. As for printers and other peripherals, they consume about 10% of the electricity, so they use about 16-17 watt.

The average cost

If you expect the average cost of electricity consumed by personal computer per month, it is enough to multiply the cost for 30 days. For example, if we take the maximum cost of one kilowatt-hour at the Moscow rates, it turns out, about of 3.80 rubles. Thus it appears that if you use a standard office computer to the limit for the entire month and the consumption of electricity from 250-350 watt/hour cost per month 950-1330 rubles (if to use the computer more than 8 hours daily, every month). Gaming computer, respectively, will consume much more electricity, therefore, and money to use such a device to spend more. Of course, the final quantity of electricity consumed depends on how much time you will use the computer and under what conditions.
