How much energy is left on the earth 15, how much energy is left on the earth

oil for about 50 years; The mineral deposit is about 120 years old; Water for about 100 years.

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.

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

How much energy does the earth have? Yes: How much energy does the Ground Mask Fiber Laughing Ball have?

The average amount of heat transferred from the Earth's interior is seconds per square centimeter, and based on the number of seconds in a year and the total surface area of the Earth, it can be calculated that the amount of heat transferred from the Earth's interior by heat conduction should be in the number of calories or joules in a year.

The most abundant energy resource on earth is solar energy. Solar energy is a renewable energy source, which is caused by the fusion of hydrogen atoms in the sun's interior to release a huge amount of nuclear energy, which produces a shortage of radiation energy from the sun. The earth's wind, water, ocean temperature difference energy, wave energy and biomass energy are all higher than the sun, so the scope of solar energy in the broad sense is very large.

Solar energy is the energy produced by the continuous process of nuclear fusion reactions inside the sun. The average intensity of solar radiation in the Earth's orbit is.

The Earth receives up to 173,000 tw of solar radiation energy. That is, the energy of the sun shining on the earth every second is equivalent to 5 million tons of coal, and the energy that hits the earth every second is coke and pink.

Solar energy in the narrow sense is limited to the direct conversion of solar radiation energy into photothermal, photoelectric and photochemical energy.

The earth's resources and energy are mainly taken from coal, oil and natural gas.

At present, there are 1 trillion barrels of proven usable oil reserves on the planet, which can be used for 45 to 50 years; 120 trillion cubic meters of natural gas, which can be used for 50 60 years; 1 trillion tons of coal, which can be used for 200 220 years. The world's proven reserves of major metallic and non-metallic mineral resources are 145 billion tons. Among them, aluminum can guarantee about 222 years, copper 33 years, lead 18 years, mercury 43 years, nickel 51 years, zinc 20 years, iron ore 161 years.

These energy sources can be used for a long time, don't worry, although the loss of resources is more serious now, but human beings are also constantly exploring new energy.
