As if solar and wind plants are substantially easier/cheaper/longer lived than hydro.
Ignoring the cost/kWH of construction, wind generation requires more than a lot of maintenance, and solar similarly. The relatively massive upfront cost of hydro is offset (or amortized, I forget) by the longevity of most dams, associated infrastructure, and generators. Mind you, the hidden costs of hydro power include displacement of the people who lived in the impoundment, the other life such as wildlife, forests etc.
No enterprise of Man is without impacts, noticeable, hidden, and future, and the responsible equation is the cost-benefit equation. Real costs, real benefits. Forward-looking.
