Does the word “sustainability” mean anything?
Wikipedia says: Sustainability is a characteristic of a process or state that can be maintained at a certain level indefinitely. Hydropower maybe the most sustainable electric power generation available. Nothing is recycled more effciently than water is by the water cycle and is stored for and used at constant generation levels. Windpower isn’t sustainable because you can not count on a certain level of wind generation, constantly. These are not moral judgements only observations of sustainability or non-sustainability. Neither way is a “should be done that way” statement, only statements of reliability. Water generation (hydropower) is more reliable than wind generation.
