Study Notes
- Energy is a force that makes things function, providing light, heat, and movement.
Renewable Energy Sources
- Renewable energy sources are inexhaustible resources.
- The sun provides solar energy, supplying light, heat, and enabling plant growth for food.
- Wind is a renewable energy source; wind turbines generate electricity, known as wind energy, named after the Greek god of winds, Eolo.
- Water's movement generates hydroelectric energy in hydroelectric plants through river currents and waterfalls.
Non-Renewable Energy Sources
- Non-renewable energy sources are finite and exhaustible.
- Petroleum, found underground, makes fuels like gasoline, but its overuse is depleting reserves.
- Coal and gas, used for heating, are also non-renewable, diminishing, and environmentally polluting.
Environmental Responsibility
- Renewable energies are environmentally friendly, so caring for the planet involves saving light and water to reduce pollution.
