sources of energy Flashcards
fossil fuel
formed from the remains of dead plants and animals buried
energy conversion for fossil fuel
chemical potential energy (fossil fuel) -> heat energy -> kinetic energy (turbine) -> electrical energy (generator)
impact on fossil fuel
burning of fossil fuel releases air pollutants and greenhouse gases, greenhouse gases contribute to global warming & climate change
solar energy
harness energy from sun
renewable
energy conversion on solar
light energy (sun) -> electrical energy (solar cell)
impact on solar
no releasing of air pollutants & greenhouse gases
disposal of solar panel must be proper or else toxic waste
hydroelectrical energy
generated by turbines by powering moving water
renewable
energy conversion of hydroelectrical
gravitational potential energy -> kinetic energy -> kinetic energy -> electrical energy
impacts on hydroelectrical
little greenhouse gases produced
kills plant
affect animal to move away
wind energy
convert energy from wind to electrical energy
renewable
energy conversion for wind
kinetic energy-> kinetic energy -> electrical energy
impact on wind
image plot of land cleared (loss of wildlife habitats)
birds killed if they collide with the blades
geothermal energy
heat stored in earth as steam to generate electrical energy
renewable
energy conversion for geothermal
heat energy -> kinetic energy -> kinetic energy -> electrical energy
impacts on geothermal
destroys wildlife habitats due to clear of land
harm environment
