1. The thermal insulation material. 36% of the world's energy consumption on the housing of heating and cooling. Switzerland and Germany built residential energy consumption "zero", according to the example room with new materials and new methods for heating and cooling, energy saving potential and immeasurable.

2. Change the light bulb. 20% of the world's electricity consumption on the lighting, 40% of the electricity is an old-fashioned incandescent bulbs consume. Under the condition of the same amount of light, energy-saving fluorescent lamp not only save energy than incandescent bulbs 75% to 80%, and the service life is reached 10 times of the latter.

3. Improve the household heat exchanger. Water heater, heater, and air conditioning energy efficiency is very poor, these only some of the real heat exchanger for the consumption of energy is used to regulate the temperature. Heat pump will change this situation. Heat pump available heat from the air or geothermal for outdoor building heating or cooling, almost no traditional energy consumption.

4. Factory equipment energy consumption. Energy all over the world about 1/3 is consumed by the industrial sector, industrial sector, has a great potential for energy saving. For example, in the last century since the 80 s, Japan's mitsubishi heavy industry companies to use steel furnace waste heat power generation, saving energy more than 70%.

5. Driving cars environmental protection and energy saving. A quarter of the world's energy for transportation, including annual produce two-thirds of the oil. Some energy saving measures in the field of transportation simply don't have to spend money, for example, keep tires properly inflated can improve energy efficiency by 6%. In addition, a petrol-electric hybrid vehicles environmentally friendly vehicles under the same fuel consumption, 20% more mileage than conventional cars.

6. Improve the refrigerator energy saving effect. More than half of household electricity used in household appliances, 1/5 of the world's carbon dioxide emissions is caused by household electricity. Since the 1980 s, manufacturers have the white home appliance such as a refrigerator energy efficiency increases by about 70%, but there is still room for improvement in this area.

7. Try to solve energy saving investment costs. Energy service companies can be energy-saving equipment needed for the modification fee, and then from the customer to save the cost of the tax credit. California, for example, some energy companies by offering additional discounts for energy-saving consumer, successfully reduced the peak electricity demand, is expected to save large amount of cost of the expansion of the power plant.

Hundred million source for industrial equipment such as plastic machine, drying machine, extrusion machines, injection molding machine, vulcanizing machine design efficient insulation solutions, such as professional aiming at the defects of traditional injection molding machine high power consumption, servo transformation efficiency can reach 30%, 60%, let you more power saving money, but also more market competitiveness.
