R And NR

Renewable Resources

• Definition: Renewable resources are resources that can be replenished naturally over a short period of time. Once they are used, they can be replaced quickly.
  • Examples:
  • Solar Energy: Energy from the sun that can be used to generate electricity or heat.
  • Wind Energy: Energy generated from wind through turbines.
  • Hydropower: Energy from flowing water, often used in dams.
  • Biomass: Organic materials, like plants and animal waste, that can be burned for energy or converted into fuels.

Non-Renewable Resources

• Definition: Non-renewable resources are resources that cannot be replaced quickly. Once they are used up, they may take millions of years to form again, if at all.
  • Examples:
  • Fossil Fuels: Includes coal, oil, and natural gas, which are formed from ancient plants and animals over millions of years.
  • Nuclear Energy: Energy produced from uranium, a mineral that is not renewable.

Key Differences

• Renewable resources can be replaced quickly, while non-renewable resources take a very long time to form or cannot be replaced at all.
• Renewable resources are generally more environmentally friendly, as they tend to produce less pollution compared to non-renewable resources.

Importance of Conservation

• It's important to conserve non-renewable resources because they are limited. Using more renewable resources can help reduce our reliance on non-renewable ones, leading to a healthier planet and more sustainable future.
