Types of hydroelectric power: How do the dam things work?

Hydroelectricity, or ‘hydro’, is generated from the energy in the water cycle of the earth. The sun evaporates water on the surface of the earth, causing it to rise up to form clouds. Clouds eventually form droplets, which then rain, snow, or hail down to the surface. Water on the surface flows downhill until it evaporates again. During this time it may become trapped in glaciers, lakes, ponds, puddles, or the ocean. Driven by the sun, the water cycle is a truly renewable resource.

We have been captivated for a long time by the intriguing possibilities inherent in combining Manitoba’s extensive hydro resources with Saskatchewan’s high-quality wind power. A number of other groups in Saskatchewan have been lobbying for greater interconnection between the two power grids to take advantage of the natural synergy that exists between wind power and reservoir-based hydro power.
