You are correct to some extent that hydropower doesn't consume water. But, I noted in one of the demerits that some water is lost by evaporation due to the impoundment.
Also, Energy from Hydropower is not used directly for lighting or heating.
Thanks for dropping by.
There will also often be a river that is deprived for water, the water from the dam may go some kilometres before it's passing a turbine an then being released into the river, another lake or the sea. This may cause big impacts on the local ecosystems.
I couldn't agree more with you @toxiben. Damming disrupt the condition of any downstream river. It could lead to partial or complete dewatering of such river.
Your contribution is well appreciated and It is really a great motivation to have a highly reputable one like you here. I will be glad to see you drop by often and perhaps have a way to get in touch with you.
Highest Regard!
Welcome sir!
