Hydroelectric energy future

Hydroelectricity, at present the most important of the clean, econonucally feasible, renewable energy options, can benefit from a water resources development project however, that is seldom the only benefit. It is clear, therefore, that hydro-power has an important role to play in the future, both in terms of energy supply and water resources development. 

Canadian utilities normally meet the base-load requirements of the grid with the most inexpensive source of electrical energy, primarily with hydroelectricity and nuclear power. Because the fraction of electricity derived from nuclear power has increased in recent years for some utilities, HWRs may be expected to operate in various modes of load following in the future. These operations may require fuel to be power cycled on a weekly or daily or even hourly basis, depending on the grid. This requirement is especially important for those utilities whose reactors are connected to comparatively small grids. 

It is generally accepted that fossil energy resources are limited, although it is a matter of debate as to how much is left (Table 5.1.9). Energy demand is rising worldwide, especially in countries undergoing economic booms like India and China. The future will show whether nuclear power will be abandoned in some countries or its share will increase as, at present, only hydroelectricity and nuclear power are the only significant alternatives to fossil fuels. 

When rain falls on high ground the water can be trapped in a reservoir and then used to drive turbines in a hydroelectric station, as it flows to lower ground. In Britain less than 1% of our energy is supplied by hydroelectric power. It makes economic sense to build more hydroelectric stations in the future. 

James Spearot In some parts of the world, there is cheap hydrogen available where there are hydroelectric capabilities. I am one of the people who believes that eventually we are going to have to look at additional nuclear energy sources in the future. In fact, I am concerned that we might be falling behind countries such as France and Korea, which are very interested in nuclear energy.
