There’s more to this water sourced energy than meets the eye! Hydroelectric energy is the simplest and first technology to generate electricity. It was first developed using dams, timber, or granite. Using this –with the requirements of one gallon of water falling 100 feet- creates 1000 watts of electricity. There are currently 30 major power plants generating more than 2000 megawatts under construction. They have been running for many years. But wait, there’s more to this amazing energy source. Interestingly, 20% of the world’s electricity use was generated by hydroelectric power in 2010. It’s the most renewable source in the world. The hydropower machine was made to catch rain water and surface run-off. It takes water from reservoirs, usually behind a dam. The water rushes in and the water gates funnel into a pipe where the force of falling water turns it. The water lands on the turbines until the shafts connect to a generator creating the one and only – energy! This process is an example of Kinetic Energy caused by letting water flow through turbines. “All this for just a little energy” you say? Well, I’m glad you asked. Actually, this process produces 24% of the worldwide energy! That supplies 1 billion people. Together, all the plants produce 675.000 megawatts of energy- that’s 3.6 billion barrels of oil. Most great inventions succeed, and this one definitely has! Hydroelectricity is completely green and safe! The machine itself sets off no pollution at all. It doesn’t need to be powered by any type of fuel (other than water, of course) which makes it nice not to have to depend on the ever-changing rates of oil. In comparison to fossil fuels and nuclear energy, it’s safer and faster. This method is highly flexible! Adjusting the water flow has never been easier. Water can be saved for times when energy or water is low. It’s a very reliable source in terms of renewability. It cannot be used up because of the water...
