In fact, the electrical energy has already been sent, and it is wasted when it is not used. The sentence itself is not rigorous, because the generation of electricity and the consumption of electricity are carried out simultaneously and balance each other. The problem is that the grid doesn't want the load to fluctuate so much that if everyone doesn't use electricity for one hour, those generators will run idle, wasting energy.
If the machine is stopped and turned on, the waste is even greater and the safety of the grid is affected.
First of all, one of the most basic characteristics of "electricity" is that electricity cannot be stored, and the production and use of electrical energy are carried out at the same time! In other words, the electricity you are using is being produced by the generator at the same time.
We have learned physics in middle school, the "power frequency" of China's power grid is 50 Hz, for a power grid system, the user's electricity we call "electricity load" (unit MW), power generation of power plants we call "power generation load" (unit MW), only when all the electricity load of a power grid = all power generation load, the power grid can maintain power frequency operation, then the power grid is safe.
Yes, this is a very demanding condition, and in reality, the job of some people is to constantly monitor the power load of the power grid to adjust the power generation load of the generator so that the two are equal. So, why is it said that "the earth turns off the lights for an hour" is a huge safety hazard for the power grid? Hypothesis 1, in this hour, many lights are turned off, which will cause the huge electricity load to disappear suddenly, and the electricity load is not equal to the power generation load, then the part of the people I mentioned above will be busy adjusting the power generation load.
In addition, when I write this thing, it is definitely not that I do not support energy conservation, on the contrary, I am a staunch supporter of low-carbon and energy-saving life. If you really want to save energy, environmental protection, and live a low-carbon life, I suggest: participate less in this kind of showmanship-based activities, deepen the concept of energy conservation into daily life, turn off unnecessary lights for a long time, reduce energy consumption, reduce carbon emissions, and give the earth a tomorrow!

This is because a lot of electricity is consumed when the equipment in the power station is restarted.
-
Because power generation and consumption are carried out simultaneously and in balance with each other. The problem is that the grid doesn't want large fluctuations in load.
-
The amount of power that is operating normally is less than the amount of power when it is restarted.
-
Because it will consume a lot of power when it is restarted later.
-
Because restarting an appliance consumes a lot of electricity.
-
Many energy machines are no longer functional, which also causes electricity to be wasted.
-
When the power is turned off, the power consumption will be even more.
-
Restarting the switch multiple times is power-intensive.

If Earth Hour is a waste of electricity, then we usually don't need to save electricity, because the working hours of the generator set of the power bureau are certain, and it is the same whether it is turned off or not, just turn on the lights 24 hours a day, I don't know who said such a fallacy.
Actually, it has nothing to do with the total amount of the generator, but everyone turns off the lights at the same time, and turning on the lights at the same time may overload the generator, understand? For example, putting 10 catties of things on a person 3 times is the same concept as putting 30 catties of something on a person at a time? If you put too much at once, you will definitely not be able to stand it.
-
Starting from small things, why can't you save electricity by turning off the lights for an hour?
Because the working hours of the generator set of the power bureau are certain, turning off the lights to save electricity by themselves will cause a waste of electricity", which is pure nonsense. The lights-out activities of some large electricity consumers, such as large shopping malls and landmark buildings in the city, will be notified and approved in advance, and the power plant and power grid will make timely load dispatching and adjustment according to these.
If you want to save electricity, I suggest you stop the phone report, the content is too nonsense.

Turn off the lights, of course. Provincial opening and attendance customs. That's it.
Like your computer monitor. The power can be set to turn off for 5 minutes. This will turn off the monitor after 5 minutes away from the computer.
And when you come back later. Move the mouse. The computer will turn on the monitor on its own.
This is a small detail of power saving. Even if a computer's monitor is 100W (in fact, the color display is about 90W), then 1 hour is oh...
-
It can be said that turning off the lights for an hour is just an appearance, and we use so many electricity resources in a year, and it is completely useless not to use it for an hour today.
Saving electricity still depends on your own consciousness, such as turning off the lights at ordinary times.
Save a little, we only have one earth.

Earth Hour is an important strategy for China's sustainable development, and China is now in the primary stage of socialism and will remain so for a long time. Earth Hour is good for the development of our country. It is not that there is a causal relationship in the power plant.
There is a connection between Earth Hour and a low-carbon economy. As we all know, in May 2010, the World Expo will be held in Shanghai, China. Moreover, the World Expo is intrinsically linked to the low-carbon economy and Earth Hour.
In short: Earth Hour is conducive to the implementation of our sustainable development strategy and to the economic development of our country.

In the face of the impact of global natural disasters, an hour of lights out around the world can save a lot of resources, and it will also reduce carbon dioxide emissions and reduce the occurrence of natural disasters.

This movement should be supported, but what I am depressed about is why it was started by the Americans, who heard that the Americans are the largest per capita resource consumers in the world.

Give Mother Earth an hour off!
Maybe you haven't looked at the stars in a long time!
Just today......

If the Americans put it forward, then they will carry it out themselves.

What is the significance of Earth Hour? When the lights were turned off around the world, the world became like this.

The proportion of civil electricity in the total power generation is not large, and the major power consumers are mainly industrial electricity; In addition, the power generation of the power plant is not fixed, but can be adjusted according to the demand of the grid by shutting down some of the units. To sum up, the activity of turning off the lights for one hour can indeed save some energy, but it will have a certain impact on the power grid, and it is a test of the power grid regulation ability.
-
The earth turns off the lights for an hour, just the lights out, not the power out. Lights off for an hour can save a lot of electricity, and its role is also to warn people to save electricity and be green and environmentally friendly. However, the electricity consumption in factories, hospitals and other places is normal, and the power plant will deliberately reduce the power generation before the power outage, that is, to ensure the normal use of electricity, but not too much waste.
-
This is also a very outrageous question!
-
Earth Hour does not have any effect on the power plant, and the power plant cannot be stopped for a moment!
Today's power plants are very large, and once they stop working, it will take several days to return to normal.
There is no way to stop working for 1 hour.
-
Of course not.
The lighting is just a drop in the bucket.

First of all, because it's a hypothesis. "If" here means hypothetical. For grammatic reasons, if it is deleted, then it becomes a description.
Second, there is no such thing as not being able to delete the "if". After deletion, the whole sentence still has a hypothetical tone, but it is not straightforward.

This is the theory of scientists, but in reality it is impossible, at least not in the near future, or if there is more investment and less income.

Maybe you don't know, maybe there are some things that can't be changed, right?

You may be wondering, we can see the news about global warming almost every day, countless experts and scholars are shouting that the greenhouse effect is causing global warming of the earth, but this winter is very cold, the two major cold waves have even been named "overlord" and "emperor", many places in China have also set the lowest temperature since the temperature record, and in early January, the central and eastern parts of Inner Mongolia even had a low temperature of minus 52. So why is there such a cold winter in the context of global warming? This may be a question that everyone is very confused. >>>More
Because the vertical stability of the earth's gravity is generally recognized in our daily life, the earth's natural force, that is, the earth's gravity, is commonly known as the "earth's fixed gravity" (also to distinguish particle microgravity). The theory of studying the meaning, function, laws and characteristics of "the earth's natural force, that is, the earth's fixed gravity", is the "earth's fixed gravity", referred to as "the earth's gravity", which is the earth's natural force generated by the earth's material mass as a whole, that is, the earth's gravity, which occurs in and to the center of the sphere, also known as the spherical gravity. The natural force of the earth, that is, the energy of the earth's body (earth) and the earth's outer space (sky) reached by the earth's gravitational force, condenses in the direction of the earth's core, and this cohesion is carried out in a vertical downward way to stabilize the energy of the things it reaches. >>>More
