Green Electricity: A Renewable Energy Source from Water Power

Green electricity, generated from the power of water reservoirs, is an essential source of renewable energy. It is produced through turbines that harness the energy of stored water in dams. By activating an alternator, these turbines generate electric current. The more water stored in the dams, the greater the energy production. This clean energy source plays a crucial role in the transition to a more sustainable energy future.

Global Leaders in Hydroelectric Energy Production

Globally, three nations dominate the ranking of hydroelectric energy producers. Two of them are newly industrialized countries (NPIs). These three countries are:

1. China

With over 1,300 terawatt-hours per year (TWh/year), accounting for 31% of global hydroelectric energy production, China takes the lead, according to Ember.

2. Brazil

Brazil currently holds the second position, but regular droughts threaten the future of these production sites, reducing the water level in dam reservoirs and compromising the reliability of this renewable energy source.

3. Canada

As the only developed country on the list, Canada takes third place, with over 500 power plants on its territory, leveraging its abundant water resources.

The Weather Dependence of Hydroelectric Power

Despite its benefits, hydroelectric power has a major drawback: its dependence on weather conditions. Rainfall directly affects the water storage level in reservoirs and the flow of major rivers.

For example, the last two summers in Europe, marked by severe droughts, significantly reduced energy production in affected countries.
