FAQ

What is a one-time energy

Primary energy, also known as natural energy, refers to the use of natural resources that have not been changed or changed. Such as coal, crude oil, natural gas, water, wind energy, solar energy, ocean energy, tidal energy, geothermal energy, natural uranium, etc.. Primary energy is divided into renewable energy and non renewable energy, the former refers to the repeated generation of natural energy, the latter with a little less, mainly all kinds of fossil fuels, nuclear fuel.

What is the difference between energy star and DLC

TUV authorized testing laboratoryThe government finds that the public service platform of small and medium-sized enterprise product testingChina, Hongkong, Australia and other lamps energy efficiency accreditation record LaboratoryLED lamps can provide a comprehensive test items: light distribution curve, UV value, light intensity spatial distribution, illumination, LM-80 lumen maintenance rate test

Which products need to be marked energy efficiency logo

As the first step in the construction of China's energy efficiency labeling system, household refrigerators and room air conditioner energy efficiency labeling system was officially implemented in March 1, 2005. According to the first batch of energy efficiency labeling product catalogue and related requirements, since March 1, 2005, every household air-conditioning and refrigerator production, sale, import Chinese must be labeled "Chinese energy label" label, no logo products will be allowed to market sales.

Mainly for PetroChina, Sinopec, the state-owned monopoly enterprises to discuss

Energy is the material basis of human activities. In a sense, the development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy technologies. In today's world, the development of energy, energy and the environment, is the world, the whole human concern, but also an important issue of China's social and economic development.

What are the new energy sources?

Microbial fermentation: many countries rich in sugar cane, sugar beet, cassava and other world, the use of microbial fermentation, can be made into alcohol, alcohol has complete combustion, high efficiency, no pollution, can be obtained by the "ethanol gasoline" diluted gasoline and alcohol rich raw materials, low cost. According to reports, Brazil has modified ethanol gasoline or alcohol fueled cars up to hundreds of thousands of vehicles, reducing the air pollution. In addition, the use of microorganisms to produce hydrogen, in order to open up new ways of energy.

What is the classification of energy?
