Study Notes
Renewable Energy Availability
- Geothermal energy is a renewable source that is available anytime as it relies on the constant heat from the Earth.
Solar-Dependent Renewable Energy Sources
- Solar energy, which harnesses sunlight, is the primary renewable energy source dependent on the sun.
- Solar power is generated through photovoltaic cells or solar thermal systems that convert sunlight into electricity or heat.
Nuclear Energy Store
- The store of nuclear energy is found in the nucleus of atoms, where energy is released through nuclear fission or fusion processes.
Efficiency in Energy Transfer
- Efficiency measures the ratio of useful output energy to input energy in a machine, indicating how effectively a machine converts energy from one form to another.
Generation of Solar Energy
- Solar energy is generated by converting sunlight into electricity using solar panels or concentrating solar power systems.
Wind Energy Generation
- The wind turns turbines to generate energy, which is then converted into electrical power.
Hydro Energy Generation
- Hydro power uses moving water, waves, and tides to generate electricity through various methods like dams or tidal energy systems.
Geothermal Power Source
- Geothermal power is created by water being heated when pumped through hot rocks underground, utilizing the Earth's internal heat for energy production.
