Busy time for a Blaenau Ffestiniog, green guesthouse. Blaenau is very lucky having a glut of renewable energy. It's 700ft high, alpine setting provides ample sun, wind and rain. It has 3 commercial hydros and a massive pumped hydro scheme that moves a whole lake up a mountain to store energy. All this is capable of providing more energy than Blaenau can ever use.
