Renewable Energy
Renewable energy is obtained from virtually inexhaustible natural sources. These sources regenerate naturally or have immense energy reserves. They are categorized into clean and polluting sources.
Clean sources include:
- Blue energy (fresh and saltwater bodies)
- Wind power
- Geothermal energy
- Hydropower (rivers and streams)
- Tidal power (seas and oceans)
- Solar energy
- Wave energy
Hydropower
Hydropower utilizes water falling from a height to move turbines. It requires reservoirs, dams, and channels. Hydropower harnesses the energy of moving water.
Radioactive Waste
Radioactive wastes contain radioactive elements with no practical use. They are byproducts of nuclear processes, fuel processing, and medical applications.
Radioactive contamination results from the dispersion of radioactive materials from accidents, usage, or disposal.
Nuclear Energy
Nuclear energy is released during nuclear reactions. It is used for power generation, thermal and mechanical applications, and has both peaceful and military uses.
