Cutting down on the amount of gas emission released every year is possible. There are many alternatives in transferring our planets generation of electricity to help. The power source that I stumbled over happened to be hydroelectricity. Hydro electricity is electricity that is generated from the water pressure using a big river. Hydro electricity is when the pressure of water is multiplied by using a dam and then transformed into mechanical electricity. These mechanisms are usually put on big rivers with a reasonably large drop of elevation. The water rushes through an opening in the dam that increases the pressure of the water. The water then runs through a hydro turbine which is a propeller that is spun by the force of the water. The energy of the spinning turbine is collected through a generator and directed straight into the power lines. This tactic of energy collection is nothing new seeing how water turbines have been around since the 19th century. It was a smart invention that has evolved into a serious source of power. These Dams can not be placed on all rivers but an increased number of hydro electric dams could decrease the amount of emissions caused by other harmful sources of energy. There are some draw backs on the use of dams but the positive results of having a hydro electric dam over rule the negative factors completely.
This idea is very interesting in places that have big rivers but i think this idea cost a lot of money
Yes, but the environmental catastrophe which results from such dams cannot be measured. See: Aral Sea, Three Gorges Dam.
Dams created upriver flood plains which create a new ecosystem where previously it did not exist. Additionally, it creates a barrier which hampers natural movement of river life, with the exception of spawning fish like salmon because dams now use dam ladders.
Regardless, I agree that the energy source is clean, but like all things there is ALWAYS a down side!
