Opening Most Sacred Heart of Jesus Prayer Have Mercy on us Most Sacred Heart of Jesus We trust in you Most Sacred Heart of Jesus Make our Hearts like unto yours AMEN What is Energy? It is simply define as the capacity to do work while resource is a general term referring to any item which is used for a specific purpose. NONRENEWABLE RESOURCES RENEWABLE RESOURCES  NON-RENEWABLE RESOURCES Non-renewable resources cannot be replenished or regenerated on a human time scale. This energy are nuclear and fossil fuels (coal, oil, and gas).  Nuclear Energy Both fission and fusion create a heat energy called nuclear energy.  EXAMPLE OF NON- RENEWABLE RESOURCES  Fossil Fuels Fossil fuels -- including coal, oil and natural gas -- are drilled or mined before being burned to produce electricity, or refined for use as fuel Fossil Fuels  Coal is a black combustible rock made up of different element such as carbon, hydrogen, oxygen, nitrogen and varying amounts of sulfur. Organic deposits from plant remains are collected in rocks and soils, submerged in water, and compressed by the weight of sediments over millions of years. Carboniferous period – the most extensive coal deposit date (290 Mya – 360 Mya). Classification of Coal according to its carbon content: Lignite is a soft, dark-brown, low-rank coal composed of 60% to 70% carbon. At higher temperatures, lagnite becomes dull, black, mid-rank Bituminous coal composed of 70% to 80% carbon. When temperature continues to increase, the bituminous coal is transformed into shiny, black, high-rank Anthracite coal composed of 95% carbon. LIGNITE BITUMINOUS ANTHRACITE Petroleum comes from the Latin word “petra” which means “rock” and “oleum” which means “oil”.  Oil was formed from the remains of marine animals and plants that lived millions of years ago that accumulated on the sea bottom and went through geologic forces and formation. Natural gas is also formed from fossil remains. Natural gas is formed when layers of decomposing organic material are exposed to higher temperatures and pressures generated within Earth.  RENEWABLE RESOURCES Renewable resources can be replenished or regenerated on a human time scale. This include geothermal, flowing water, wind, solar, and biomass.  Renewable energy is energy generated from natural sources such as sunlight, wind, water, various forms of biomass, and geothermal heat. Energy that can be replenished faster than fossil fuels.  Biomass refers to biological or plant and animal material used as fuel for the generation of electricity, other forms of fuel, and heat. Hydroelectric Power – It converts the kinetic fast moving water into electricity. SOLAR ENERGY How does wind energy works? “Without electricity, there can be no art.” -Nam June Paik Given a choice, what sources of energy will you use to power your community? Why? Discuss its pros and cons.
