Wind vs. Water Power
Advantage - water power requires a river, lake, etc. Wind is found everywhere.
Disadvantages – the wind changes in speed. Power can only be generatedwhen the wind is blowing within effective and safe limits. A method of storing excess power for moments of no (or too much) wind is required.
