NOTE

RENEWABLE AND NON-RENEWABLE RESOURCES

1. Renewable Resources: Renewable resources are derived from naturally replenishing sources like sunlight, wind, and hydropower. It offers a sustainable and environmentally friendly alternative to conventional fossil fuels, helping reduce carbon emissions and combat climate change.

Examples of renewable resources includes:

  1. Solar Energy: Harvested through solar panels to generate electricity.
  2. Wind Energy: Utilizes the kinetic energy of the wind to produce power via wind turbines.
  3. Hydropower: Captures the energy of flowing water, commonly through dams or water turbines.
  4. Biomass: Uses organic materials like wood, crop residues, and waste to generate energy.
  5. Geothermal Energy: Taps into the Earth's internal heat for heating or electricity generation..

Advantages of Renewable resources

  1. Sustainability: Can be replenished naturally, promoting long-term availability.
  2. Environmentally Friendly: Typically have lower environmental impact and greenhouse gas emissions.
  3. Diverse Sources: Various types like solar, wind, and hydropower provide versatility in energy production.

Disadvantages of nonrenewable resources

  1. Intermittency: Reliance on weather conditions for some sources like solar and wind can lead to intermittency.
  2. Initial Costs: Installation of renewable energy systems often requires higher upfront investment.
  3. Land Use: Large-scale renewable projects may necessitate significant land use, impacting ecosystem

2. Non-Renewable Resources: Nonrenewable resources are finite substances, such as fossil fuels (coal, oil, and natural gas), that cannot be replaced on a human timescale. Their extraction and use contribute to environmental challenges like pollution and climate change. As these resources are limited, there's a growing emphasis on transitioning to sustainable alternatives to ensure long-term energy security and reduce environmental impact.

Examples of non-renewable resources are:

I. Fossil Fuels:

   - Coal: Mined for electricity generation and industrial processes.

   - Oil: Extracted for various purposes, including transportation and the production of plastics.

   - Natural Gas: Used for heating, electricity generation, and as a fuel source.

II. Minerals:

   - Metallic Minerals: Such as iron, copper, and aluminum used in construction and manufacturing.

   - Non-metallic Minerals: Like salt, gypsum, and diamonds, used for various industrial applications.

III. Nuclear Fuels:

   - Uranium: Used in nuclear power plants for electricity generation.

Advantages of nonrenewable resources

  1. Energy Density: Fossil fuels, especially, possess high energy density, providing efficient energy output.
  2. Infrastructure: Well-established infrastructure for extraction, refinement, and distribution of nonrenewable resources.
  3. Consistency: Nonrenewable sources provide a consistent and reliable energy supply.

Disadvantages of nonrenewable resources

  1. Depletion: Finite nature leads to resource depletion, raising concerns about long-term availability.
  2. Environmental Impact: Extraction, processing, and combustion contribute to pollution and climate change.
  3. Geopolitical Issues: Dependency on certain regions for nonrenewable resources can lead to geopolitical tensions.

EVALUATION: 1. Differentiate between renewable and nonrenewable resources.

  1. Give 3 examples each of renewable and nonrenewable resources.
  2. Mention 3 advantages and 3 disadvantages of renewable resources.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
