Energy Resources
- Consumption: using a resource for energy or other purposes.
- Natural resources: raw materials found in the air, water, or land, including minerals, fuels, climate, vegetation, and soil that humans can use.
- Sustainable development: improving people's lives without wasting resources or harming the environment.
Types of Energy Resources
Non-Renewable Resources
- Are finite, meaning they will eventually run out.
- Examples:
- Fossil fuels (coal, gas)
- Minerals
- Nuclear Energy
Renewable Resources
- Can be used over and over again.
- Examples:
- Solar power
- Geothermal energy (using heat from the earth's core)
- Wind power
- Water (hydro-electric) power
- Also includes: trees, clean water, fish, wildlife, and soil.
Factors Affecting Resource Demand
- Population growth: more people means more energy used.
- Economic development: as countries develop, they build more factories, homes, shops, etc., requiring more energy and resources.
- Increasing wealth: as countries get richer, they consume more energy and resources.
- Technological advances: new technologies require energy and resources.
Interesting Facts
- Fuelwood (wood used for energy) provides 35% of developing countries' energy needs.
