The very small village of Long Rusu in Sarawak, population 20, is supplied with hydroelectricity, thanks to a spirit of gotong-royong.
It is a cold evening, not unusual for the hamlet of Long Rusu where the temperature often falls below 20°C after the sun sets. Mountain weather is chilly and not made for cold showers.
I switch on the water heater and test the water with my hand. It is hot, almost scalding – perfect for a hot bath.
