Now she forces me to  wash  three times a day”. A six-year old boy in Phnom Penh, after water was delivered  by  piping. Told by Ek Sonn Chan, General Director Phnom Penh Water Supply Authority, Cambodia. The aim of this book is to describe how solar photovoltaic (PV) and wind energy have a huge potential to supply clean water for the developing world, in particular in areas with no electric power grid connection. Off-grid technologies can form a significant part of the solution, all the way from household level to village or community level. Small-scale off-grid systems can provide not only lighting but also energy for pumping to gain access to water and for treatment to purify and reuse water. The cost development of renewable energy has been remarkable and will make electric power affordable even for the poorest. Since 2010, the cost of key energy devices has declined dramatically: LED lighting is 95% cheaper, solar PV 60% and battery storage 75% less expensive.
