The steps to creating hydroelectric power are simple. The first [[#|step]] is to build a dam on a large river. Next, when the dam stores lots of water, gravity causes the water to fall, through the penstock inside the dam. When the water reaches the end of the penstock, a turbine is turned by the moving water. The shaft from the turbine turns into a "generator", which produces the power. Since the power lines are connected to the "generator", the power lines carries the power. The water continues passed the propeller and trails back in to the river, passed the dam. Therefore, the hydroelectric power converts into electricity.
The second way to create [[#|hydroelectric power]] is pumped storage, which is when hydroelectric power is a pumped into a storage plant. First, power is sent from a power grid to electric generators. The power then spins the [[#|[[#|turbines]]]] backwards. The turbines pump water from a river or resevoir where the power is stored. Then water released from the upper resevoir goes into the lower resevoir and the cycle goes back and forth. This causes the turbines to spin forward to generate power. A major source of California's electricity is hydroelectric power. In 2007, hydroelectric power plants produced 43,625 gigawatt-hours of electricity. California has average 400 hydroelectric power plants located on the eastern mountain ranges. The larger power plants are operated by the U.S. Bureau of Reclamation and the state's Department of Water Resources. The smaller ones are operated by utilities. 2 types of conventional hydroelectric is facilities and run on rivers. Hydroelectric power plants provide power. In hydroelectric power plants water is pumped during off-peak from a reservoir at a lower elevation. Some pros about hydroelectric power is that hydroelectric power plants consume low-cost off-peak electricity and generate high-value on-peak electricity. Some cons about hydroelectric power is that sometimes when you build hydroelectric power plants, you can have a loss of wilderness resources. Also they can create land slides or erosion to occur. They can also damage cultural or historical sites. Some interesting facts about hydroelectric power for example, hydroelectric power is the most significant renewable source of energy. Hydroelectric power is the only [[#|renewable energy]] source that can compete against fossil fuels. While hydroelectric power is the force of energy of moving water, it is a clean source and doesn't cause pollution. It uses the Earth's water cycle to create kinetic energy, then is converted to electricity. Hydroelectric power makes up 9% of the U.S's [[#|power supply]]. Hydroelectric power can't be a main source of energy everywhere because it needs to have fast flowing waters yea round. Hydroelectric power is very efficient energy because some [[#|turbines]] can do efficiency of 95% +. In conclusion, hydroelectric power provides about 20% of the world's electricity, and is the main source of power in more than 30 countries.
