When I'm in Thailand I always think the electricity is very cheap. In the UK I pay 27.86p / ฿11.94 a KwH and my gas heating is 7.37p / ฿3.16 a KwH. Goodness' knows what the prices will be next year though. ฿4.72 / £0.11p a KwH really is cheap after all, and there's no VAT on it either (5% in the UK).
