Hydroelectricity is a renewable source of electricity which is derived from the movement of water.
How Water Creates Electricity
Water is something we use in our everyday lives, and sometimes without even realizing it. Whether we simply use it to wash the dishes or to take a shower, we might not realize how important to renewable energy water really is. With ocean energy and other water sources, you might be using renewable energy right now. Hydroelectricity is a system in which electricity is created through the movement of water, either by force or by gravity. In doing so, the electricity is created without having to use any resources other than the water itself.
The movement of the water causes the potential energy to rise, allowing for the creation of electricity. And since the water doesn’t have to be moved in many instances, there is little upkeep or energy needed once a dam or a hydroelectric station is put into place.
What to Remember about Water Energy
When water is used to create electricity, there is little money which needs to be spent once the plant is created. In addition, instead of simply cleaning water of industrial waste and municipal waste so that it can be used for drinking, the water can be used to power up entire cities without adding to the emissions in the air. The cost of oil for fuel is also not in the equation, so the power is cheap, effective, and easy to manage.
However, the main concern with hydroelectricity is that dam failures can cause a variety of problems. In addition, the dam might be a target for those who want to cause harm to the area via terrorist or other violent acts.
About 75% of the Earth’s surface is covered in water, with much of it moving. Why not take advantage of this natural feature and create renewable energy?
