I’m reading a book called “alternative energy demystified” – it’s for beginners apparently, but … (p7)
“Disadvantages of wood burning:
* Wood stoves can be dangerous: Before installing one, read the instruction manual. You should wear safety glasses and completely cover yourself (including your hands) with fireproof clothing when working around an active wood stove”.
* The fire requires constant attention”
etc etc. It then goes on to hydro: (P197)
“Whenever energy is taken from a river by a hydroelectric facility, that energy is not available for use in any form further downstream”.
