E-book Clean Water Using Solar and Wind: Opportunities to Reach Outside The Power Grid
Clean water and basic energy are needed for a decent life. This is taken for granted by most people in the world. Yet still, in 2018, more than 650 million people lack clean water and around 1,000 million people do not have the electric power that could enable them to light their homes, cook their food and access clean water.This book addresses this issue and claims that there are better opportunities than ever to satisfy the basic needs of clean water and energy for all.The unique development of renewable energy over the last few years brings new hope for millions of people. Those living in remote areas, outside the national electric power grids, will now have a realistic opportunity to receive the benefits of clean energy. This in turn will open up possibilities of obtaining clean water and enable people to escape poverty, fight hunger, improve health and support education.The United Nations has defined 17 Sustainable Development Goals (SDGs). Two of these relate to clean water and clean energy. However, without these two essentials it will hardly be possible to reach the other 15 goals. 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.
