Two economics of energy conservation

Shivering in the cold, the first thought is to keep warm, but the cost of heating makes them less wealthy people were forced to adopt a "green" heating. That's what Mr. Dreyfuse, executive director of the New York Connell society, recently delivered to his family in a workshop that he taught the energy saving and money saving skills to the poor.

He said that heating and air conditioning accounted for 42% of household energy consumption, such as computers and other household appliances accounted for 28%, hot water systems accounted for 14%. He tried to correct the misconception that when it comes to energy conservation, the idea is to replace incandescent lamps with energy-saving lamps. But this does not have much effect, the total household electricity consumption has not been reduced, because the lamp accounted for only 10% of the total energy consumption of the whole family". He gave for people on the economic accounts calculations, if you use the cotton plug to open the door and windows, less wear more clothes before you go to bed or go out and don't forget to switch off the heating device, so you can save $more than 1 thousand a year.

This is to save money, is the poor economics, but it is hard to say is energy-saving. If you wear three sweaters to keep out the cold, you'll only be saving energy for the rest of your life. Energy saving means less without reducing the quality of life of the energy, which requires the inventor and manufacturer can provide a large number of energy-saving products to the market, the price must be lower than the traditional product, otherwise it is energy saving, but no money.

Just explain the poor economics to the poor in the weevers, New York Fort Frank village and city officials are considering traffic lights in the village by the incandescent lamp replaced LED (light emitting diode) lamp, because the lamp is much brighter than incandescent bulbs (20 watts equivalent to 100 watts), longer life (the difference a few months and a few years), so it can save a lot of money for the municipal. There are other benefits, such as the reduction of the number of bulbs, the corresponding reduction of the lift car attendance and traffic jams, which are the city and the public to save money.

With the aid of different weevers, Frank village and city officials about Mr Gore's followers, require the use of energy-saving products in the premise of reducing the quality of life, even if such product price is much more expensive than traditional products anyway. Considering that the LED light is brighter and more colorful than the incandescent light, it can be said that the quality of life is improved.

However, the city of Fort Frank village officials in their proposal is not listed a lot of reasons to save money? Indeed, but any achievement projects are built on the replacement effect rather than the replacement cost accounting, so Frank village and city officials forgot LED lamp and incandescent lamp to tell the public the same brightness difference. As a good thing, I found such a price from elsewhere: LED lamp prices more expensive than incandescent lamps, several light emitting diodes and a price will be the price of incandescent lamps, but usually each LED signal required by the 300 to 500 diodes. In other words, buy a LED lamp, equal to buy one hundred incandescent lamp.

In addition, the production of hundreds of diodes must be much higher than the production of an incandescent lamp. However, the production of this kind of small electronic products, such as diodes, has been transferred to the poor countries of the third world, which consumes a large amount of energy in order to reduce the consumption of energy. Connell fraternity weevers and Frank village and city officials representing different economics, economics of the former is poor and poor areas, the latter is rich and rich in economics.
