Systems/Energy Types/Energy Resources Flashcards
HydroPower
GPE to Electric energy
Pro: Doesn’t release greenhouse gasses/ Cheap to maintain/ Reliable
Con: Expensive to build/ Disturbs ecosystems
Solar Energy
Energy from the sun is turned into electricity or passive heating for water(EM energy-electric energy)
Pro: No carbon emissions/ low maintenance costs
Con: Lack of sunlight can make solar panels very inefficient/ A lot of energy is wasted
Wind Energy
Wind energy is utilized by turbines(mechanical energy-electric energy)
Pro: Doesn’t release any greenhouse gasses/ It has low operating costs
Con: Harms flying animals/ It’s very loud
Geothermal Energy
Energy from heat in Earth’s crust. (Thermal energy to electric energy.)
Pro: Always available/ Mostly quiet
Con: Costly to build/ Location is restricted to sites of volcanic or seismic activity
Biomass
Energy from burning organic, recently living matter. Can be plants or animals(Chemical energy to Electric/Thermal energy.)
Pro: Widely available/
Con: Releases greenhouse gasses/ Can lead to deforestation
Coal
A fossil fuel formed from buried(mostly plants but some animals) that lived millions of years ago. (Chemical energy-thermal energy.)
Pro: Produces lots of energy/ It’s cheap to use
Con: Releases carbon emissions/ Destroys the environment
Oil
Formed from buried animals & plants under bodies of water. Turned from solid to liquid. Propane is its gaseous form.
Pro: It’s cheap/ Energy dense fuel source
Con: Causes pollution of the air/ Drilling for oil disrupts ecosystems
Natural Gas
Made up of mostly methane. Used for electricity, heating, & cooking. Formed from buried animals & plants under bodies of water.
Pro: Easy to transport/ Affordable
Con: Emits greenhouse gasses/ Can be toxic to humans
Nuclear Energy
Energy released during nuclear fission/fusion.
Pro: Low operating costs/ Doesn’t release any carbon
Con: Expensive to originally build a plant/ Produces radioactive waste
Conduction
The transfer of heat through direct contact. From an object of high temperature to an object of low temperature.
Convection
The transfer of heat by the circulation of heated parts of a liquid or gas. Convection Currents.
Radiation
The transfer of heat through waves
