What are natural resources?
Any form of substance in nature that is not man-made and can meet the needs of human life and production can be called natural resources, which form the basis of human survival. Such as solar radiation, atmosphere, water, organisms, earth, various minerals and energies, etc. are all natural resources.
2. Types of natural resources
Human life is closely linked to natural resources. Daily needs, transportation, and industrial development all depend on natural resources to run smoothly or more conveniently. For ease of management and use, they can be divided into the following categories:
1. Inexhaustible Resources: Resources that will not be reduced due to human use. These resources are in stable supply and abundant. . Such as the enesolar power, wind power, tidal power, global water resources, atmosphere and climate, etc.
2. Non-renewable resources: These resources are limited in quantity and will disappear once exhausted. Such as minerals, oil, natural gas and other fossil fuels.
3. Renewable Resources: Resources that can be regenerated or recycled. Such as water, soil, biological resources.
Understanding energy
1. In addition to their direct use, natural resources can also be converted into electricity or electricity for use.
For example: electric lighting, using gasoline as fuel for cars and motorcycles.
2. Taiwan Electric Power Company uses hydropower, fuel oil, coal, gas and nuclear power to generate electricity. Among them, non-renewable resources represent 87% and natural resourcess renewable 13%. Reserves of natural resources such as oil, coal and uranium mines are limited and may be exhausted.
3. Oil is a widely used resource and is expected to be exhausted in less than a century. We must save energy and develop new energy sources.
4. Natural resources that can be used to generate electricity include: solar energy, biomass energy, hydropower, wind energy, tides, geothermal energy, ocean, etc. . For example: solar water heaters, solar street lights, hydropower, wind power.
