Energy Sources Summary

Renewable and Non-renewable Energy Sources

• Natural Resources: Materials from nature used to support life and economic gain. Examples include minerals, forests, water, and fertile land.

Key Concepts

• Energy Forms:

  • Renewable: Constantly replenished (e.g., solar, wind, hydropower).

  • Solar Energy: From the sun, used for electricity and heating. Example: Calatagan Solar Farm in the Philippines (63.3 MW).

  • Wind Energy: Generated by air movement (e.g., Bangui Wind Farm with 20 turbines, 1.65 MW each).

  • Hydropower: Electricity from moving water (e.g., Magat Dam).

  • Geothermal Energy: Heat from the Earth; the Philippines is second in production worldwide (e.g., Tongonan Geothermal Power Station).

  • Biomass: Energy from plant materials; San Carlos BioPower generates 20 MW.

  • Non-renewable: Finite resources leading to pollution and environmental threats.

  • Coal: Black/brown rock used for heat and electricity, non-renewable.

  • Oil/Petroleum: Thick liquid for fuel production.

  • Natural Gas: Formed under heat/pressure, found in rock layers.

  • Nuclear Energy: Power from atomic fission/fusion, can provide significant energy.

  • Peat: Organic material used as fuel found in wetlands.

Impact on the Environment

• Renewable sources reduce greenhouse gas emissions and combat climate change.

• Non-renewable sources contribute to pollution and environmental degradation.

Conclusion

• The transition to renewable energy is crucial for preserving the environment and ensuring sustainable energy for the future.

• Personal energy choices can impact the planet positively.

Energy Saving Tips

• Turn off lights when leaving a room.

• Use energy-efficient appliances.

• Consider renewable energy sources like solar panels.
