What is the concept of a kilowatt-hour? How do thermal power, photovoltaic and wind power generate one kilowatt-hour of electricity?
Have you been traveling recently? Did you see wind turbines and photovoltaic power generation equipment along the way?
Electricity is inseparable everywhere in life.
Do you really understand "one kilowatt-hour" since you are the one who uses electricity every day?
One kilowatt-hour of electricity is not a word on the watt-hour meter, nor is it an electricity bill of 0.5 yuan(Chinese market price).
One kilowatt-hour (1KW h) is a unit of energy instead of the power unit (KW) we usually see.
1 kWh = 1 kW X 1 hour = 1000 watts X 1 hour
Simply put, a kilowatt-hour of electricity is the electrical energy consumed by an electrical appliance with a power of 1000W for 1 hour.
How is one kilowatt of electricity produced?
Depending on the energy used, there are usually thermal power generation, wind power generation, photovoltaic power generation, nuclear power generation, and hydropower generation.
Thermal power generation burns coal. To generate one kilowatt-hour of electricity, it consumes 310 grams of coal and 4 liters of purified water, 190 grams of diesel and 59 grams of natural gas, which produces 160 grams of carbon dioxide, 272 grams of carbon dust, 6.2 grams of sulfur dioxide, and 15 grams of carbon oxides. Hydroelectric power generation is not so polluting, but only 630 cubic meters of water can produce one kilowatt-hour of electricity; a 400-watt photovoltaic panel can produce one kilowatt-hour of electricity when exposed to the sun for 2.5 hours; wind power generation, a 2MW wind turbine, when the rated speed rotates for 3.5 seconds , it generates 1.94 kWh of electricity, which means that the fan can generate one kWh of electricity when it rotates for half a revolution.
The effect of one kilowatt of electricity is beyond your imagination! Don't look at the price of one kilowatt-hour electricity is not high, but it can do a lot of things, countless overtime late at night, one kilowatt-hour electricity will accompany you with a desk lamp, which can light up you for 40 hours; when you are killing time with your phone, at that time, the router was silently supported for 10 days to ensure you a continuous high-quality network; for you as a foodie, a 66-watt refrigerator was run for 15 hours to ensure you eat fresh ingredients; One kilowatt of electricity can also support the air conditioner to provide you with 1.5 hours of cooling in the hot summer; when you are unwell with a cold, one kilowatt of electricity can boil 8 kilograms of water; support you when playing games and reading novels; one degree of electricity gives you your mobile phone fully charged more than 100 times, and you no longer have to be afraid to appear when you are playing with your mobile phone: "Your battery is insufficient"... Isn't it shocking?
China Gwell is professional for making EVA/POE solar cell encapsulation film production line. The solar film is widely used in the PV(photovoltaic) module. After elven years' development, the machine has been upgraded to a higher level. When it was in the early 2010, the main weakness of the Chinese EVA film machine was its line speed. At that time, the line speed was only 3 meters per minute. And now in 2021, the line speed can reach to 13-15 meters per minute. If you want to know more information about the machine model and its price, please feel free to contact us.
