Hydropower is the most widely used renewable energy source worldwide, according to analysis of Energy Information Administration data performed by RS Components. As a result of global warming, depleting fossil fuel stocks and volatile oil prices, countries around the world are focusing on developing their renewable energy strategies in a drive for a global clean energy transition. Producing renewable energy is now more critical than ever and all types are increasing exponentially in market share as the costs of production decrease. The benefits of using renewable energy are potentially life-changing for the world’s population and include reductions in air and water pollution, damage to public health, wildlife and habitat loss, and global-warming emissions. Since most renewables don’t require water for cooling, they significantly reduce the water requirements for power production compared to fossil-fuelled power plants.
