EARTH’S NATURAL RESOURCE S How do we humans destroy natural resources?  Natural Resources  Are materials that can be used to support life  Provide energy for living things to work as well as for machines to run or operate  Supplied by sun or Earth’s natural processes.  Only sunlight comes from the outside.  Plants and algae (producers) need sunlight to make food.  Sunlight produces heat that moves the wind onto the surface of Earth and drives waves and currents in the sea and the ocean.  Sunlight is harnessed to generate electricity. ENERG Y Where do other forms of it come from? The diagram shows the different sources of energy in the Philippines and the percentage of each source. Guide Questions 1. What are the different sources of electricity in the Philippines? 2. What is the main source of energy in Luzon, Visayas and Mindanao and what is the percentage? 3. Based on the diagram, what can you say about the sources of  Sources Of Energy RENEWABL NON- E RENEWABLE  Geothermal Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the Some of the operational geothermal power plants in the Philippines are: Tiwi Geothermal Plan in Maibarara Geothermal Plan Tiwi, Albay in Sto. Tomas, Batangas  Makban Geothermal Power Plant, Philippines  HYDROELECTRIC  Hydroelectricpower(hydropower) is derived from the energy of falling or moving water to generate electricity. Among purposes, water is widely used to produce electricity.  Hydropower is a proven, mature, predictable, and price competitive technology. A number of-on- and off-grid hydropower plants have been built throughout the country, including impounding dams and run-off-river types.  Impounding Dams are able to supply energy during peak and off-peak hours while run-off-river types supply electricity whenever capable, depending on the volume of water that is discharged from the watersheds.  A turbine converts kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy fro the turbines into electrical energy. The generator power stepped up to a higher voltage from Some of the operational hydroelectric power plants in the Philippines are: Magat Hydroelectri c Power Plant Ramon, Isabela, Philippines Binga Dam in Itogon, Benguet Wind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can convert mechanical power into electricity. Wind turbines harness the power of the wind and use it to generate electricity. When the wind blows, the blades are Some of the operational wind energy in the Philippines are: Bangui Wind Farm, Bangui, Ilocos Norte Caparispisan Wind Farm Pagudpud, Ilocos Norte, Philippines  Solar Energy Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or A photovoltaic (PV) cell, commonly called a solar cell, is a non-mechanical device that converts sunlight directly into electricity.  Photovoltaicpanels are installed for the conversion of thermal energy into electricity, while solar panels convert solar radiation into heat. This is why these solutions do not compete with each other. Instead, they may complement each other.  Solar PV (photovoltaic) panels, most commonly installed on rooftops, turn sunlight into electricity without producing carbon emissions. This can be used to power your home, heat your water or be stored in a battery for later use. Some of the operational solar power plants in the Philippines are: Calatagan Solar Powe Plant Calatagan, Batangas Solar Farm in Cadiz City, Negros Occidental Electrochemical(Batter ies) Some of the fossil fuels power plant found in the Philippines are: Coal Sual Power Plant, Pangasinan, Philippines  SPC Cebu Diesel Power Plant, Cebu City  Natural Gas/Ilijan Combined- Cycle Power Plant, Batangas City Bataan Nuclear Power Plant  Activity Time Directions: 1. I will divide the group into 3 groups. 2. In your group, assign a leader, a presenter, a writer, a material manager, and a timekeeper. 3. Each group will prepare materials that will be used in writing your activity. 4. You are only given 10 minutes to prepare the activity and then present it to the class. Group 1- Table Summary Group 2- Construct a Venn Diagram Group 3- Create an Acrostic Poem How can we conserve energy?
