Renewable resources: solar energy, geothermal energy, hydropower, wind energy, marine energy; mineral resources; petroleum resources; natural gas ; Nuclear fuel.
Renewable resources refer to resources that can continue to be used after being developed and used by humans, or that can be regenerated in a short period of time, or that can be recycled. It is a type of natural resource that can be repeatedly formed in a certain cycle after use, consumption, transformation, combustion, disposal, etc., which has the characteristics of self-renewal and recovery and can be used continuously. renewable resources, It is a clean energy that strengthens construction and promotes use in sustainable development.
Non-renewable resources refer to natural resources thati cannot be regenerated for a long time after human development and use. It mainly refers to various minerals, rocks and fossil fuels found in nature, such as peat, coal, oil, natural gas, metallic minerals, non-metallic minerals, etc.
Which of the following are renewable resources ( ) A. Oil, natural gas, solar energy B. Forest, wind energy, land C. Hydro energy
Renewable resources are as follows:
1.
It comes directly from solar radiation, mainly providing heat and electricity.
2. Bioenergy.
Green plants convert solar energy into chemical energy through photosynthesis, which is stored in the body. It can flow in one direction along the food chain and is ultimately converted into energythermal and lost by combustion. and anaerobic fermentation to obtain biogas.
3. Wind energy.
Energy is provided by solar radiation. The difference in atmospheric pressure caused by unequal cold and heat causes horizontal movement of air. Wind formation mainly obtains energy from wind turbines.
4. Water energy.
The energy provided by solar radiation creates a water cycle. Warm, moist ocean air rises when heated, and solar energy is converted to potential energy when precipitation forms over high mountains. flows downward and the potential energy is converted into kinetic energy. It is the energy of water, which mainly obtains energy through hydroelectric generators.
5. Ocean energy.
The energy contained in the movement of sea water, including tides, waves, ocean currentsques, etc., is also inexhaustible. Tidal energy comes primarily from the gravity of celestial bodies such as the moon and sun, and energy from ocean waves and currents. It is affected by wind and mainly produces electricity thanks to the kinetic energy of the tides.
6. Geothermal energy.
It comes from the decay of radioactive elements inside the earth and can be used for geothermal energy production and heating.
7. Hydrogen energy.
Obtain energy through combustion or fuel cells.
8. Nuclear energy.
Obtain energy from nuclear power plants.
The concept of renewable resources:
Resources that are regenerated and updated through natural processes and therefore used repeatedly by humans are called renewable resources. They are also called resourcesrenewable resources, such as plants, microorganisms, degradable plastic bags, water resources, geothermal resources and various natural biomes, forests and. meadows, aquatic life, etc.
Renewable natural resources can continue to regenerate and renew themselves, multiply and grow, maintain or increase their reserves, and rely on sources to regenerate under conditions specific temporal and spatial nature at this stage. Non-fossil energy mainly refers to natural energy sources such as wind energy, solar energy, hydropower, geothermal energy and marine energy.
Why is solar energy classified as a renewable energy source? Will solar energy ever run out?
| A. Oil, natural gas and solar energy are non-renewable resources. This therefore does not answernot in the sense of the question. B. Forests, wind energy and land are all renewable resources. So correct. C. Hydroelectricity, geothermal energy and coal are non-renewable resources. So this doesn't answer the meaning of the question. D. Gold, silver, copper and iron are all minerals and non-renewable resources. So this doesn't answer the meaning of the question. Then choose: B |
I may know this friend's question. Will the sun burn forever and bring energy to humanity? A hundred years, a hundred million years, is that okay? Can this last 100 million years? Can this last 10 billion years? Of course not. Because the lifespan of the sun is 10 billion years, 5 billion years have passed. That's only 5 billion years away. Of course, humans cannot regenerate their energyie before 10 billion years.
But it is indeed a delicate question. In today's popular words, it is "Jingfeng".
The renewable energy we are talking about now simply means that it will not run out at any predictable time. Renewable energy refers to non-fossil energy such as wind energy, solar energy, hydropower, geothermal energy and ocean energy. It is an inexhaustible source of energy. Compared to inexhaustible renewable energy sources, it is less harmful to the environment. or The harm is very low, the resources are widely distributed, and they are suitable for local development and use. Therefore, Pacific Energy belongs to renewable energy.
Renewable energy includes solar energy, hydropower, wind energy, biomass energy, wave energy, tidal energy, the energy of differentocean temperature, geothermal energy, etc.
Can be played repeatedly in nature. It is an infinite source of energy that can be automatically regenerated without human intervention, as opposed to an infinite source of non-renewable energy.
This world is only relatively "eternal", nothing is eternal.
The universe also has a lifespan. We now know his date of birth. Once, about tens of billions of years ago, some people said that the empty talk about the time of his death was reasonable and that there was no unified view. Every morning the sun rises in the east and every evening the sun sets in the west. This continuous generation has been going on for billions of years, giving birth to life and human beings, and now there is no sign that it is not continuing. AlsoSolar energy is a huge source of renewable energy.
The sun frees 3.78x10 26J of energy in space every second. Earth divides that scoop by 1/2.2 billion to get 1.72x10 17J, or about 1,300 watts of light per square meter, and the total. The quantity reaches 48 billion degrees. This is the total development of the Three Gorges Dam of 15 million, or the energy of more than 3,000 Hiroshima atomic bombs per second. This energy occurs every moment of the day, and even on cloudy days, this energy radiates. over the clouds. If the sun didn't blow up the earth with this sneeze, this light would continue. This won't change for at least 100 million years.
