Hydroelectric Power - Definition, Renewable, Advantages
                     HYDROELECTRIC POWER | DEFINITION, RENEWABLE, 
ADVANTAGES
Hydropower has long been a traditional source of clean energy and 
deserves to be rediscovered and renewed. It can help drain marshy land 
and irrigate fields and can be produced by either large stations or small 
plants. It even has huge potential for domestic use.

Hydropower is a renewable source of energy. The energy generated 
through hydropower relies on the water cycle, which is driven by the sun, 
making it renewable
RENEWABLE 
SOURCE OF ENERGY

Hydroelectric power is a domestic source of energy, allowing each state 
to produce its own energy without being reliant on international fuel 
sources.

Impoundment hydropower creates reservoirs that offer recreational 
opportunities such as fishing, swimming, and boating. Most hydropower 
installations are required to provide some public access to the reservoir 
to allow the public to take advantage of these opportunities.

Hydroelectric power is flexible. Some hydropower facilities can quickly go 
from zero power to maximum output. Because hydropower plants can 
generate power to the grid immediately, they provide essential backup 
power during major electricity outages or disruptions.

Hydropower is affordable. Hydropower provides low-cost electricity and 
durability over time compared to other sources of energy. Construction 
costs can even be mitigated by using preexisting structures such as 
bridges, tunnels, and dams.

The organic residues that decompose in reservoirs can also be a source 
of methane, one of the main greenhouse gasses. In the past, this fact 
fueled controversy over whether hydropower could genuinely be 
considered an entirely green energy source.

With water courses contained within pre-established reservoirs, 
hydropower stations also help avoid flooding as well as helping to drain 
marshy land where stagnant water tends to accumulate.

Often, when it comes to hydropower, the focus is on the impact the 
stations can have on the environment – but hydropower can also benefit 
the environment. 
For instance, having more water available in reservoirs means richer 
vegetation, which in return attracts more animals and boosts the 
population in the surrounding area.
