Energy Flashcards
considered as one of the most important resources on earth
energy
consist of hydrogen and helium gases which produces tremendous amount of energy in the form of electromagnetic radiation
sun
inexhaustible or may be replaced
renewable energy
would last only for a period of time
nonrenewable energy
defined as the capacity to do work
energy
energy which is being stored or at rest and available for use
potential energy
energy in motion or working energy
kineti cenergy
– study of energy transformations
thermodynamics
states that energy is neither created nor being destroyed but is converted from one form to another
law of conservation of energy
states that when being transformed is converted to low -quality energy in a form of heat
law of entrophy
When energy is changed from one form to another, a more useful is converted to a less useful form
law of entrophy
about 80 percent of the world’s energy sources comes from extraction and burning of minerals during this times
industrialization
were formed hundred of million years ago from remains of plants and animals
fossil fuel
– consuming fossil fuels that its production and such sources
nonrenewable energy
energy sources which are continuously present and can be replenished
renewable energy sources
renewable energy include
➢Solar
➢Geothermal
➢Wind
➢Moving water
➢Biomass
are all forms of fuels used in the modern world, either for heating, generation of electrical energy, or for other forms of energy conversion
energy resources
Unlimited (non-exhaustible)
renewable
Limited (exhaustible)
nonrenewable
Readily available in nature
renewable
Not readily available in nature
nonrenewable
Lower total cost
renewable
higher total cost
non-renewable
Less (low carbon emission and footprints)
renewable
Adverse (high carbon emission and footprints)
nonrenewable
non-renewable sources which comes from remains of organisms, compressed in oxygen free environmen
fossil fuel
Are being formed million years ago as product of photosynthesis with the aid of
solar energy
fossil fuel
Formation of this is slower than it is being used
fossil fuel
Being formed after dead plants are being decomposed by bacteria and fungi
fossil fuel
Include petroleum, natural gas, and coal
fossil fuel
is considered as the largest source of commercial energy in the world
petroleum or crude oil
Known as light oil which comes from the ground as black colored liquid which consists of hundred of different combustible hydrocarbons along with small amounts of sulfur, oxygen, and nitrogen impurities
petroleum
deposited within the earth’s crust or under the sea floor
crude oil
In order to extract this, developers tend to drill wells in the deposit and is drawn out of rock pores, flows into the bottom of the well and is pumped into the surface
crude oil
process done to oil that was done to be heated
refining
product of crude oil distillation such as gasoline, diesel fuel, and furnace oils
petrochemicals
it has been projected by geologist that crude oil will be depleted sometime this year
2050
Three active petroleum producing fields in Malampaya (gas and condensate), and Galoc (oil) off shore north-west Palawan and Alegria (oil) onshore Cebu
crude oil
Malampaya produces what petroleum
gas and condensate
Galoc petroleum produces
oil
palawan and alegria petroleum plant produces what
oil
Problem is with regards to its transportation, usually oil is being transported throughout the globe through supertankers and sometimes results to leaks and spills
crude oil
result to water pollution just like what happened in Guimaras which resulted to death of phytoplankton, corals, and fishes
oil spill
Can contaminate the soil and underground water
oil spill
evaporation of oil products and incomplete combustion of oil fuels results to this
air pollution
hard black mineral consisting of large percentage of carbon, small amounts of sulfur which upon combustion is being released as sulfur dioxide (SO2) in the atmosphere
coal
Burned in power plants to generate electricity
coal
Extracted either through surface mining or underground mining
coal
There are currently ___ coal-fired power plants currently operating throughout the Philippines, with total installed capacity of 9.88 gigawatts
