Energy-saving lamps profitably or not

Our country is fast strides towards a market economy. Each year, electricity prices will rise and approach the world (25-30 cents per kWh). In such circumstances we will have to address the issue of energy savings.

Main ways to save in the apartments is the use of energy efficient appliances (Class A), heaters with high efficiency, saving the world, the use of dvuhtarifnyh counters, etc.

Below is a comparative survey of energy saving lamps and ordinary in the infrared. Shooting made thermal imager NEC 7102 made in Japan.
Numeral 1 denotes an incandescent lamp 100 watts. Its temperature is about 120 degrees Celsius.
Numeral 2 denotes an incandescent lamp 25 watts. Its temperature is about 50 degrees Celsius.
Numeral 3 denotes saving lamp 20W. Its temperature is about 50 degrees Celsius.
Numeral 4 denotes saving lamp 11W. Its temperature is about 50 degrees Celsius.
Incandescent at 25 W (№ 2), and energy-saving lamps (№ 3,4) have approximately odinkovuyu temperature, but low-light bulbs illuminate the room much better. Incandescent 100 watt lights in the room as well as energy-saving lamps at 20 watts, but its temperature by more than 2 times higher. Thus, only part of the energy is lost, wasted in heating the air.

Consider the application of energy-saving bulbs to save electricity. Let's try защита дома от плесени to answer the following question: Is it advantageous to use the data for the lamp current tariffs for electricity.

Baseline data:
Electricity prices now 1.3 rubles per kWh. Each subsequent year, the price will rise by 15%.
The average time of energy-saving lamp 4000-6000 hours. Take, for calculating 4000 hours.
The average time of a standard lamp 1000 hours.
Every day, the lamp burned for about 3 hours. In the year of 1000 hours of lamp is lit, thus sparing lamp will last for four years. During this time, we will burn four conventional lamps.
Let's look at the savings chetyrehrozhkovoy chandelier with 4 lights.

When world prices for electricity savings of much more. For example, at a price of 5.6 € / kWh (20 cents), the fee for ordinary lamps will be 7168 rubles for saving 2330. Savings 4830 rubles.

You choose to save or not. But even if the energy-saving lamp fails before (if it is Chinese), the saved money can buy many of these lamps.
The basic principle of choice

A. Do not believe the inscription on the box that replaces 11 W 60 W, etc. (Especially for inexpensive Chinese lamps). Buy the lamp more power. Ie, if you replace the conventional lamp 80 watts do not take saving lamp 20 W, take a 23 or 26 watts (in any case, it concerns the Chinese lamps).
Two. Do not change the bulb where they should often include off, or where there are very rarely included light (bath, toilet).
Three. General Electric is always better to space resanta and the like.

I was on staff at WED Enterprises (Now Disney Imagineering), as a disability accessibility expert. Born and lived in Anaheim, worked out of Burbank and at Disneyland Park. I also went over all of the Walt Disney World blueprints to find problems related to accessability issues, and went to Florida quite often to make sure corrections to the blueprints were made. I also worked with EuroDisney and Tokyo Disneyland before my retirement as an advisor.
