Final answer:
Wind and hydroelectric power require complex systems to generate electricity. Wind power is more variable and has a lower capacity factor compared to hydroelectric power. Hydroelectric power has seasonal intermittency and is not easily implemented on a personal scale.
Step-by-step explanation:
Wind and hydroelectric power both require complex systems to generate electricity. However, there are some differences between the two. Wind power is more variable than hydroelectric power due to the variability of wind. This means that wind turbines have a lower capacity factor compared to hydroelectric turbines. On the other hand, hydroelectric power has already been heavily exploited and expanding its usage beyond its current level can be challenging. It also has seasonal intermittency and is not easily implemented on a personal scale.
