Study Notes
Wind Energy
- Generates power by converting kinetic energy of moving air into mechanical energy using turbines.
Hydropower
- Energy derived from the movement of water, supplied by rivers or dams.
- Benefits include being renewable and reducing greenhouse gas emissions.
- Major disadvantage: interferes with aquatic ecosystems.
Solar Energy
- Energy sourced from the Sun.
Biomass Energy
- Derived from organic materials used as fuel.
- Benefits include renewable nature and waste reduction.
Heat Energy
- Flows due to differences in temperature, establishing a thermal equilibrium.
Geothermal Energy
- Utilizes heat from the Earth's interior.
- Benefits include high efficiency and low environmental impact.
- Major disadvantage: location-dependent availability.
Tidal/Wave Energy
- Generates power by harnessing the kinetic energy of moving water to drive turbines.
Nuclear Energy
- Energy released through nuclear fission or fusion.
- Considered non-renewable due to reliance on finite uranium resources.
Building Energy Rating (BER)
- Assesses the energy efficiency of buildings.
- The BER rating provides insights into energy consumption and sustainability.
Environmental Benefits of Renewable Energy
- Renewable energy sources reduce greenhouse gas emissions and overall pollution compared to non-renewable sources.
