Study Notes
- Core concepts covered include natural vs human-made resources, renewable vs non-renewable resources, and various energy sources.
Natural and Human-Made Resources
- Natural resources occur naturally in the environment.
- Examples of natural resources are air, water, and soil.
- Human-made resources are created or altered by humans from natural resources.
- Examples of human-made resources are paper, plastic, and buildings.
Renewable and Non-Renewable Resources
- Renewable resources are naturally replenished, so they don’t run out.
- Examples of renewable resources are solar and wind energy.
- Non-renewable resources can be depleted.
- Examples of non-renewable resources are fossil fuels and nuclear energy.
Energy Sources and Electricity Generation
- Solar energy employs PV panels to convert sunlight to electricity.
- Wind energy uses wind to turn blades, spinning a generator.
- Biomass involves burning biomass to create steam, which spins turbines connected to power generators.
- Natural gas is used for heating, cooking, and hot water.
- Oil is burned in boilers to produce heat.
- Hydro electricity uses the power of flowing water to feed into an electrical grid.
- Ocean energy harnesses energy from waves, tides, and currents.
- Coal is burned to heat water, creating steam that spins turbines connected to power generators.
- Geothermal energy uses heat from the earth.
Renewable vs Non-Renewable Identification
- Solar energy is renewable.
- Wind energy is renewable.
- Biomass is renewable.
- Natural gas is non-renewable.
- Oil is non-renewable.
- Hydro electricity is renewable.
- Energy from the ocean is renewable.
- Coal is non-renewable.
- Geothermal energy is renewable.
Advantages and Disadvantages of Energy Sources
Solar Energy
- Advantage: Renewable, cost-saving, reduces carbon footprint.
- Disadvantage: High initial costs, energy production depends on weather (sunshine).
Wind Energy
- Advantage: Renewable, clean, cost-effective.
- Disadvantage: Visual and noise pollution, high initial cost.
Biomass
- Advantage: Renewable, readily available, reduces landfill waste.
- Disadvantage: High costs, lots of land needed, environmental impacts.
Natural Gas
- Disadvantage: Non-renewable resource that produces greenhouse gas emissions.
- Advantage: Lots of natural gas
Oil
- Advantage: Easy to transport, used in a lot of infrastructure and vehicles.
- Disadvantage: Non-renewable, pollution.
Hydro Electricity
- Advantage: Renewable, clean.
- Disadvantage: High Initial Costs
Energy from the Ocean
- Advantage: Renewable, cost
- Disadvantage: Environmental impact
Coal
- Advantage: Relatively cheap.
- Disadvantage: Non-renewable, environmental impact, health risks, air pollution, danger to miners.
Geothermal Energy
- Advantage: Renewable, low carbon footprint.
- Disadvantage: High upfront costs, location-dependent (resources are not found everywhere).
