How much energy is on the planet What is the energy on the planet?

Nature is extremely rich in energy. Gale carries tremendous energy and sweeps across the land; The waves rushed to the shore in a torrential manner. Scientists estimate that there is about 1,000 times more wind energy on Earth than the total amount of coal burned in the world. It's a pity that humans haven't used much yet.

The water flow also has a lot of energy. When a flood comes, it can tear down and submerge villages. People build various water conservancy projects, not only to prevent water disasters, but also to use the flow of water to serve the people. According to the survey, most of the world's hydropower resources are still unused.

Coal is the most commonly used energy source in China. China's proven coal reserves are 650 billion tons. Giving priority to coal mining and letting the "black gold" sleeping underground serve mankind is an important guarantee for the victory of the "four modernizations" construction.

Oil and gas are currently important energy sources in the world. China's sedimentary rocks that can be used for oil and gas are 4.2 million square kilometers on land and 1.3 million square kilometers on the coastal continental shelf, with an estimated total reserve of 300.16 billion 100.1 billion tons. At present, only a few billion tons have been proven, so there is a great prospect for development.

Wind energy, water flow energy, fuel energy, etc., are all converted from solar radiation energy. When sunlight hits plants, plants absorb solar energy, convert it into chemical energy, and store it in plants. Both coal and oil evolved from ancient organisms.

Therefore, it can be said that solar energy is the main energy source for human beings and the earth, and some people estimate that if a desert area with a length of 300 kilometers and a width of 100 kilometers receives all the solar energy received in a year, it can meet the world's current energy needs in a year!

There is also a huge amount of energy stored in the interior of the earth. In 1883, Krakatoa volcano in Indonesia erupted, sending ash to an altitude of 27 kilometers. This is a release of energy from the Earth's interior, much more powerful than an atomic bomb.

The energy released by the big ** is even more amazing: the energy released by a seven-level ** is about 2 1015 joules, which is equivalent to more than 550 million kilowatt-hours of electricity, and the energy released by the largest ** is equivalent to the work of a 1 million kilowatt power plant.

The total amount of electricity generated in 20 or 30 years!

There is also a lot of heat and atomic energy stored in the interior of the earth, and a lot of energy is stored in the sea. In short, the earth is rich in energy, waiting for us to exploit it.

Don't worry about energy depletion, if you have solar energy, you won't run out of energy.

Just as many Western countries now use solar power generation in their homes, and almost no electricity bills are paid, this should be a trend.

In addition, coal and oil will be used up, but they still have to be used, and there will be natural gas when they are used up, otherwise there will be geothermal, tidal energy, don't worry about pulling.

Coal is only enough for 95 years.

But perhaps something that could replace coal was already being worked out at that time.

But it's better to save it.

There's a lot more.

The teacher said (maybe he was lying to us).

Wait for the Earth to become a white dwarf.

It's hard to say this question, but it depends on human self-discipline.

Solar radiation is the main source of energy for the survival of life on earth. It is also the main energy source for the progress of human society.

It's not hard to understand why creatures collapse to survive, right? Without the sun, the food and drink are gone, the people are gone, and everything is dead.

Energy for Human Society:

Wind energy (wind power): This is caused by the sun's heating of the ground and indirectly heating the air to make it flow.

Hydroelectric power: It is still the energy of the sun that is absorbed by the atmosphere and the water is turned into steam to move to the upstream rainfall.

Fossil fuels: Coal and oil are produced by ancient organisms absorbing solar energy and then burying them underground.

Non-solar: Geothermal, mainly due to the heat generated by the decay of the Earth's own radioactive elements. Accounts for a very small part.

Nuclear energy, the energy produced by the fusion of heavy elements and hydrogen, is directly used by humans. The share is also smaller. France, which has the largest number of nuclear power generation, accounts for 12% of the country's electricity generation

I think the main energy source on earth should be solar energy; Part of the energy on the ephemeral branch ball is from celestial bodies other than the earth, the other part is the energy contained in the earth itself, and the other part is the energy surplus that the earth interacts with other celestial bodies and then produces a surplus of energy.

The main energy source is coal; It is produced by the continuous precipitation of the corpses of ancient creatures or rivers.

Oil, which is currently the most important energy source on the earth, is not clear about its formation, but may be related to the movement of the earth's crust.

Solar energy is the most abundant energy resource on earth.

Solar energy is almost not limited by geography, and it is easy to collect, can be directly developed and utilized, does not need to open pants for mining and transportation, and will not pollute the environment, which is one of the cleanest energy sources and the largest energy that can be developed in the world today. In the case of fossil fuels are decreasing, as an emerging renewable energy source, solar energy has become an important part of human energy use and is constantly developing.

Solar energy refers to the pure energy generated by the fusion of hydrogen atoms in the sun and hydrogen helium to release a huge amount of nuclear energy, which is used to generate electricity or power water heaters in modern times, and most of the energy required by human beings comes directly or indirectly from the sun.

The most abundant energy resource on earth is solar energy. Solar energy is not only one of the cleanest sources of energy, but also the largest energy source that can be developed in the world today. Solar energy is a renewable energy source derived from solar radiation energy, which can be directly developed and utilized without geographical restrictions.

Currently, solar energy is mainly used to generate electricity or to provide energy for water heaters. The vast majority of the energy required by human beings comes directly or indirectly from the sun.

Solar Pros:

1. Universal: The sun shines on the earth, there is no geographical limit, no matter land or sea, no matter mountains or islands, it is everywhere, it can be directly developed and utilized, easy to collect, and there is no need for mining and transportation.

2. Harmless: The development and utilization of solar energy will not pollute the environment, it is one of the most clean energy, and this is extremely valuable in today's increasingly serious environmental pollution.

3. Enormous: The solar radiation energy that reaches the earth's surface every year is equivalent to about 130 trillion tons of coal, and its total amount is the largest energy source that can be developed in the world today.

4. Long-term: According to the estimation of the rate of nuclear energy produced by the sun, the storage of hydrogen is enough to last tens of billions of years, and the deficit blind life of the earth is about billions of years, in this sense, it can be said that the energy of the sun is inexhaustible.

Most of the energy on the earth is the sun, and only the sun can provide all kinds of energy for the growth of all things.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets, asteroids, meteors, comets, outer Neptune objects, and interstellar dust in the Taizheng Nai Yang system all revolve around the Sun, and the Sun revolves around the center of the Milky Way.
