How is thermal pollution produced by power plants
Atmosphere heats up
Fukushima Daiichi

What is biomass
Organic matter that can be used for fuel with combustion
What is biodiesel
Derived from animal fats and oils, transesterification leads to fuel
Photovoltaic cells
Made from silicon, they absorb light which leads to electron flow with conductive metal and electricity
How is geothermal generated
Power plants tap into naturally heated water and steam to power turbines
Fuel cells
Made from anodes, cathodes, and PEM-high production costs but doesn’t use combustion
