Study Notes
- Renewable energy is derived from limitless natural sources
- Examples include the sun, wind, water force, and Earth's internal heat
- Renewable energy sources naturally replenish, ensuring they don't deplete
Solar Energy
- Solar energy originates from the sun, reaching Earth as light and heat
- Solar panels capture sunlight and convert it into thermal energy for uses such as heating water
Eolic Energy
- Eolic energy harnesses the power of air movement or wind
- Windmills convert wind into electrical energy
Tidal Wave Energy
- This energy is created by the motion of sea waves or the fluctuation of tides
Hydraulic Energy
- Hydraulic energy is produced from stored water in reservoirs or artificial lakes
- In a dam, water falls from a height and flows through a hydroelectric factory
- Here the water's force is converted into electrical energy
Geothermal Energy
- Geothermal energy is generated from the heat stored within the Earth
- It can be used for heating or generating electricity
Advantages of Renewable Energies
- Renewable energies are environmentally friendly, emitting no CO2 or greenhouse gases
- These energies are limitless as they come from naturally replenishing resources
- Renewable energies are safer for health because they don't produce toxic residues
Disadvantages of Renewable Energies
- Renewable energy resources are not universally available
- Countries with shorter daylight hours cannot produce as much solar energy
- Renewable energy availability can be unpredictable
- It depends on natural phenomena that cannot always be accurately predicted, such as rainfall
Transition to Renewable Energies
- Accelerating the shift to renewable energies is vital
- This is necessary to achieve global energy objectives and protect the environment
