Renewable Energy

1. Relating to the generation of electricity from the movement of water, typically using dams and turbines.
5. The ability to meet the needs of the present without compromising the ability of future generations to meet their own needs, a core principle guiding the development and use of renewable energy sources.
7. The natural movement of air, harnessed by wind turbines to generate wind energy or wind power.
10. Relating to the heat energy stored beneath the Earth's surface, harnessed for electricity generation or heating systems.
11. The movement of energy through a body of water, often used to generate electricity through wave energy converters.
12. Fuels derived from organic matter, such as ethanol from corn or biodiesel from vegetable oils, used as alternatives to traditional fossil fuels.

2. The ratio of useful energy output to the total energy input in a system, a key factor in maximizing the benefits of renewable energy technologies.
3. Relating to the natural rise and fall of sea levels caused by the gravitational forces of the moon and sun, harnessed for generating electricity.
4. A clean and versatile energy carrier that can be produced from various renewable sources, used in fuel cells to generate electricity or as a fuel for vehicles.
6. Organic materials, such as wood, agricultural residues, or animal waste, used as a renewable energy source through processes like combustion or fermentation.
8. Relating to or derived from the sun, such as solar energy which is harnessed through solar panels to generate electricity.
9. Energy sources that are naturally replenished on a human timescale, such as sunlight, wind, and water.
