Study Notes
Energy Resources
- Energy resources are materials or elements used to produce energy, such as heat, electricity, or mechanical energy.
- Sources are categorized as renewable or nonrenewable.
Types of Energy Resources
- Renewable: Naturally replenishing sources like the sun, wind, and water. They are sustainable and do not deplete over time.
- Nonrenewable: Sources with a finite amount of resources that will run out or cannot be replenished within human timescales. Fossil fuels (coal, petroleum, and natural gas) are examples.
Renewable Energy
- Derived from naturally replenishing sources (sun, wind, water).
- Sustainable, reducing pollution and greenhouse gas emissions.
Solar Energy
- Description: Converts sunlight into electricity using photovoltaic cells in solar panels.
- Advantages: Abundant, environmentally friendly, low maintenance after installation.
- Disadvantages: High installation costs, energy production depends on weather and daylight.
Wind Energy
- Description: Generated by converting kinetic energy of moving air into electricity using wind turbines.
- Advantages: Sustainable, cost-effective in windy areas, no direct emissions.
- Disadvantages: Turbines can be noisy, require specific locations, and may impact bird and bat populations.
Hydroelectric Energy
- Description: Uses flowing or falling water, often through dams, to generate electricity.
- Advantages: Reliable and renewable energy source; helps with water storage and irrigation.
- Disadvantages: Expensive to build dams, can displace communities, and disrupt aquatic ecosystems.
Geothermal Energy
- Description: Heat energy from the Earth, using reservoirs of hot water below the surface.
- Advantages: Renewable, comes from the Earth's mantle.
- Disadvantages: High upfront costs (megawatt capacity plants cost ~$2-$7 million).
Biomass
- Description: Renewable energy source from plants and algae; Trees, crops, and municipal waste are consistently available.
- Advantages: Zero carbon footprint; lower net carbon dioxide emissions than coal and gas.
- Disadvantages: Expensive to gather, transport, and store; large land requirements for production facilities.
Nonrenewable Energy
- Limited sources that will eventually run out.
- Primarily fossil fuels (coal, petroleum, and natural gas).
- Carbon is the primary element in fossil fuels.
Fossil Fuels
- Description: Energy sources from ancient plants and animals.
- Advantages: High energy density; efficient for power generation.
- Disadvantages: Cannot be replenished; depletion over time; release of carbon dioxide and other greenhouse gases, contributing to climate change.
Nuclear Energy
- Description: Released from the atomic nucleus (fission or fusion).
- Advantages: Low carbon footprint; reliable energy source.
- Disadvantages: Risk of accidents (e.g., Chernobyl, Fukushima); radioactive waste disposal (long-term hazard).
