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
