NOTE
RENEWABLE ANDNON RENEWABLE ENERGY
Renewable Energy
Renewable energy refers to energy derived from natural resources that are replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. These energy sources are abundant and environmentally sustainable.
Renewable Energy Examples: Solar Energy, Wind Energy, Hydropower, Biomass Energy, Geothermal Energy
Renewable Energy Uses
- Renewable energy is used for electricity generation, heating, cooling, transportation, and various industrial and commercial applications.
- It offers clean, sustainable alternatives to fossil fuels, reduces greenhouse gas emissions, mitigates climate change, and promotes energy security and independence.
Renewable Energy Misuse
- Despite its environmental benefits, renewable energy deployment may face challenges such as intermittency (e.g., solar and wind power), land use conflicts, and high initial investment costs.
- Improperly planned renewable energy projects can have negative environmental impacts, such as habitat disruption, biodiversity loss, and landscape changes.
Non-Renewable Energy
Non-renewable energy refers to energy derived from finite resources that cannot be replenished within a human timeframe, such as fossil fuels (coal, oil, natural gas) and nuclear fuels (uranium). Once these resources are depleted, they cannot be replaced.
Non-Renewable Energy Examples:
- Fossil Fuels: Coal, oil, and natural gas extracted from the Earth's crust and burned to produce electricity, heat, and transportation fuels.
- Nuclear Energy: Harnessing energy from nuclear reactions in uranium or plutonium to generate electricity in nuclear power plants.
Non-Renewable Energy Uses
- Non-renewable energy sources are used extensively for electricity generation, transportation, industrial processes, and heating in homes and buildings.
- They provide reliable and high-density energy sources that have fueled economic growth and technological advancement.
Non-Renewable Energy Misuse
- Non-renewable energy sources are finite and contribute to environmental degradation, air and water pollution, and greenhouse gas emissions, leading to climate change.
- Dependence on non-renewable energy sources poses risks of resource depletion, price volatility, geopolitical tensions, and energy insecurity.
How energy generation affects quality of life
Energy generation significantly impacts quality of life in several ways:
- Reliable energy sources enable access to necessities like clean water, heating, cooling, and lighting, improving living conditions and health outcomes.
- Energy generation fuels industries, businesses, and transportation, driving economic growth and creating job opportunities, thus enhancing standards of living.
- Clean and sustainable energy sources reduce air and water pollution, mitigating health risks and promoting a safer environment for communities.
- Electricity powers educational institutions, facilitates online learning, and supports communication technologies, enabling access to information and connectivity worldwide.
- Efficient energy systems power transportation networks, enabling mobility and access to goods and services, which are essential for economic and social activities.
EVALUATION: 1. Differentiate between renewable and nonrenewable energy
- Identify 4 uses and Misuse of renewable and nonrenewable energy
- Describe how energy generation affects quality of life
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the students positively
