Renewable resources are natural resources that can be replenished or regenerated naturally over relatively short periods of time, making them sustainable for long-term use. These resources are contrasted with non-renewable resources, such as fossil fuels, which take millions of years to form and are depleted faster than they can be naturally replaced.

Here several types of Renewable Resources:

Types of Renewable Resources

1. Solar Energy
   • Source: The sun.
   • How It Works: Solar panels convert sunlight directly into electricity using photovoltaic cells, or solar thermal systems concentrate sunlight to produce heat for electricity generation.
2. Wind Energy
   • Source: Wind.
   • How It Works: Wind turbines convert wind's kinetic energy into mechanical power, which is then converted into electricity by a generator.
3. Hydropower
   • Source: Flowing water.
   • How It Works: Dams or run-of-the-river systems use the energy of flowing or falling water to turn turbines connected to generators, producing electricity.
4. Biomass
   • Source: Organic materials (plant and animal waste).
   • How It Works: Biomass can be burned directly for heat or converted into biofuels (like ethanol and biodiesel) or biogas through various processes (e.g., fermentation, anaerobic digestion).
5. Geothermal Energy
   • Source: Heat from the Earth's interior.
   • How It Works: Geothermal plants use steam produced from reservoirs of hot water found below the Earth's surface to generate electricity or provide direct heating.
6. Tidal and Wave Energy
   • Source: Ocean tides and waves.
   • How It Works: Tidal energy exploits the rise and fall of sea levels, while wave energy harnesses the energy of surface waves, both of which can be converted into electricity using various technologies.

The number of solar panels required for a typical house depends on several factors, including the household's energy consumption, the location's solar irradiance, the efficiency of the solar panels, and the available roof space.
