|
+- hydroelectric
|
saves natural resources
doesn't require matenience costs available 24/7 reliable floods disturbs ecosystem displaces fish changes water quality holds back sediment |
|
|
+- Tidal
|
no air pollution when running
perpetually renewable reliable and predictable more energy/efficient vibrations disrupt wildlife initially expensive, can't be utilized everywhere |
|
|
+- Fossil Fuels
|
being designed to reduce pollution
coal is abundant and locally obtained runs 24/7 nonrenewable mining is removing mountains air pollution |
|
|
+- fuel cell
|
clean
can be used long time can be used anywhere expensive lots of energy needed to obtain hydrogen |
