Solar energy is a ______ energy source (optional “renewable” or “non-renewable”). At present, public

(1) Solar energy can be obtained continuously from nature and is a renewable energy source;

(2) During the day, solar energy is converted into electrical energy in addition to normal use, in excess. energy is stored inside the battery, running lights and lights shine at night. The energy conversion in this process is as follows: solar energy is converted into electrical energy; excess energy is stored in the battery, which is the conversion of electrical energy into chemical energy at night, the battery is used to power traffic lights and lighting; , which is the conversion of chemical energy into electrical energy.

So the answer is: renewable chemical energy; electric energy.

The sun is the “mother energy” of humanity, and solar energy belongs to ______ (fill in “can” or “cannot”) energiesrenewable. Xiao Ming's solar water heater every day

For people on Earth, solar energy should be classified as a "renewable energy source" because compared to the lifespan human, the time it takes for solar energy to emit energy is approximately infinite. But in fact, for the sun itself, the energy emitted by the sun has a certain limit.

The energy emitted by the sun is obtained through the nucleation reaction on the surface of the sun. is a chemical that can release a large amount of energy. The current hydrogen bomb relies on the nucleation reaction to release the energy contained in the material. The nucleation reaction requires raw materials, particularly relatively small atoms (such as hydrogen atoms). At high temperature and high pressure, the molecular movement is so violent that the collision and fusion phase of atomic nuclei occurs. In thisprocess, the total mass of the material is reduced and the reduced mass is converted to energy and released. E=M*C*C

Since the raw materials for the polynuclear reaction on the sun are limited, so the nucleation reaction on the sun will stop one day, but that day is very far away . According to contemporary physicists' estimates, solar energy will be exhausted in about 5 billion years...

But 5 billion years is so far away... So, from one From a human point of view, it is correct to say that solar energy is a renewable energy source...

From a cosmic point of view, it is correct to say that solar energy is a non-renewable resource.. Haha

There is There is no link. The above is all I learned in high school.. I am still confident in my knowledge.. Haha

Solar energy is primary energy or secondary energy?

< p>(1) Solar energy can be obtained continuously atfrom the sun and can be reused, and it is a renewable energy source;

(2) As the question says, the solar radiation energy obtained by Xiao Ming's solar water daily heating is E=6.3×107J,

(3) The solar cells we use convert solar energy into electrical energy and achieve photoelectric conversion

So the answer is: Yes; strong>Primary energy.

Solar energy is a renewable energy source and is an indispensable part of human life

Solar energy is a renewable energy source. kind of renewable energy, which refers to thermal radiation energy from the sun. Its main manifestation is often called solar rays, it is generally used to generate electricity or provide energy for water heaters. , it mainly used the heat provided by solar radiation to survive, and since ancient times, humans also know how to use sunlight to dry objects and use it as a method of making food, such as making salt and dry salted fish.

As for primary energy, it refers to unmodified energy obtained from nature or energy converted and directly used, such as raw coal, crude oil, natural gas, hydropower, eo energylink, solar energy, ocean energy. tidal energy, geothermal energy, natural uranium ore, etc.

Disposable energy is divided into renewable energy and non-renewable energy. The first refers to natural energy that can be produced repeatedly. including solar energy, wind energy, tidal energy, geothermal energy, etc. The latter is less used and mainly concerns various types of fossil and nuclear fuels, essential for life
