What is the concept of one kilowatt hour of electricity? How to generate one kilowatt hour of electricity?

People's daily lives are inseparable from electricity. You who use electricity every day, do you really understand one kilowatt hour of electricity?

1. What is the concept of one kilowatt hour of electricity?

One kilowatt hour of electricity is not a word on the meter, nor is it 0.5 yuan. One kilowatt hour (1 kW·h) is an energy unit, not the power unit (kW) we usually see.

1 kilowatt hour = 1 kilowatt hour = 1 kilowatt × 1 hour = 1000 watts × 1 hour

Simply put, one kilowatt hour of electricity is the energy consumed by an electrical appliance with a power of 1000W working for 1 hour.

2. How is one kilowatt hour of electricity generated?

Depending on the energy used, there are usually thermal power generation, wind power generation, photovoltaic power generation, nuclear power generation, hydropower generation, etc.

Thermal power generation burns coal, which requires 310 grams of coal and 4 liters of net, 190 grams of diesel and 59 grams of natural gas, producing 160 grams of carbon dioxide, 272 grams of carbon dust, 6.2 grams of sulfur dioxide, and 15 grams of carbon oxides. One kilowatt hour of electricity.

Hydroelectric power doesn’t pollute as much. However, 630 cubic meters of water can produce one kilowatt hour of electricity. A 250-watt photovoltaic panel in photovoltaic power generation can produce one kilowatt hour of electricity in the equivalent of 4 hours in the sun. A 2MW wind turbine in wind power generation can rotate once at rated speed, 3.5 It generates about 1.94 kilowatt-hours of electricity per second, which means that the fan can generate one kilowatt-hour of electricity when it rotates half a circle.

3. What exactly can one kilowatt hour of electricity do?

The effect of one kilowatt hour of electricity is beyond your imagination! Even though the price of one kilowatt hour of electricity is not high, it can do a lot of things.
