13. 13. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Effect of fossil fuel The combustion of fossil fuels leads to the release of pollution into the atmosphere. They are causes of the global warming. Greenhouse gas emissions result from fossil fuel-based electricity generation.
14. 14. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Nuclear Fuels The other form of non- renewable resource used to produce energy, nuclear fuels, is primarily obtained through the mining and refining of uranium ore. Uranium is a naturally occurring element found within the Earth's core.
15. 15. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose The Philippines has large reserves of many natural resources. these are oil, natural gas and coal. Other sources of energy that can be harnessed include geothermal energy and hydroelectricity.
16. 16. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Oil barrels The Philippines' proven oil deposits currently stand at 138 million barrels. Natural gas flame Natural gas deposits in the Philippines are located offshore, above the country's deep- sea oil reserves. The Philippines possesses 3.9 trillion cubic feet of natural gas reserves.
17. 17. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Coal mining The Philippines holds 260 million short tons of usable coal reserves. While it has recently increased extraction, consumption still far outpaces production, forcing the country to rely on imports to meet demand.
18. 18. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Other sources of energy Geothermal Energy Currently, the Philippines is the second highest producer of geothermal energy. The government has set a goal to surpass the United States as the highest producer in the world.
19. 19. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose THE PRODUCTION OF GEOTHERMAL ENERGY In the Philippines geothermal energy already provides 27% of the country's total electricity production generated in power plants. Geothermal power plants are on the islands Luzon, Negros, Mindanao and Leyte. Power plant in Tongonan, region Ormoc City, Leyte (Picture: PNOC)
20. 20. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Hydroelectricity Hydroelectricity centers in the Philippines generate 2,900 megawatts of electricity, which is 19 percent of the country's total electricity consumption. The rate of production has remained constant for decades, but there are plans to introduce more hydroelectric centers.

23. 23. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Hydroelectricity is the term referring to electricity generated by hydropower. The production of electrical power through the use of the gravitational force of falling or flowing water.
24. 24. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose The heat inside the Earth produces steam and hot water that can be used to power generators and produce electricity, or for other applications such as home heating and power generation for industry.
25. 25. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose The sun is our most powerful source of energy. Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic, concentrated solar power, solar architecture and artificial photosynthesis.
26. 26. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Wind energy is captured by wind turbines and used to generate electricity. As offshore wind speeds average ~90% greater than that of land, so offshore resources can contribute substantially more energy than land stationed turbines.
27. 27. Nat. Sci. 4- Environmental Science/ECOLOGY Prepared by: Bryan F. Mose Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-derived materials which are specifically called lignocellulosic biomass. biomass includes plant or animal matter that can be converted into fibers or other industrial chemicals, including biofuels.
