What is Hydroelectricity?
It is electricity that is generated when water behind a dam is allowed to pass through, causing a series of events to occur that lead to the production of electricity.
The electricity, in the form of an alternating current, is converted to a high voltage current in the transformer.
Although the use of hydroelectricity cuts down on most greenhouse gasses, the reservoirs can still produce significant amounts of methane gas and carbon dioxide.
