Hydro Energy

It's hard to imagine that water can be used to create electricity. The two are a dangerous combination that should never mix, right. True, so never bring your stereo in the shower with you.

Hydro energy is electricity made using water. Sounds weird, right? Especially since it's dangerous to mix the two. The water never comes in contact with the electricity. How it works is, water flowing down a river is used to spin turbines inside a generator. Large rivers with fast flowing water work the best.

Hydro Facts

1Canada is the largest producer of hydropower in the world. The United States is second.

1Hydropower is clean. It doesn't produce any greenhouse gases or other air pollution. It also doesn't generate any waste products that might need special handling or disposal. Because it's carbon-free energy, hydropower doesn't burn fossil fuels, which release the same amount of carbon dioxide as the annual exhaust of 62.2 million cars (half the cars on US roads.)

1With the good, comes the bad. Hydropower doesn't pollute the air but large hydroelectric generating stations can damage the environment. The natural flow of water to the sea can sometimes be changed, which harms plant and animal communities along the way.

1Like solar and wind energy, electricity from water is renewable. Water from rivers is a natural resource so it doesn't come with some of the problems other energy sources have, such as cost and insufficient amounts. Hydropower converts kinetic energy from falling water into electricity and never uses up more water than nature produces.

1Hydropower doesn't cost a lot of money. On average, the cost for hydropower operations and maintenance is only one-third the cost of a nuclear or a fossil fuel powered facility. That's not including fuel costs. Lower costs mean more jobs and also helps the economy.

1Another good thing about hydropower is it's flexible and reliable. Hydropower can be turned on almost immediately to meet the fast growing electricity demands. Facilities can easily respond to emergency power situations (like when California had their power crisis) and provide constant energy with water.

If you have a stream running through your backyard does that mean you could use it to create energy? Possibly. If you live near the ocean you might even be able to use the energy from waves to make electricity in the future.

What Energy Source Would U Tap Into?

  • Tap into the oceans for major hydroelectricity.
  • Solar energy is the way of the future.
  • Who needs a new energy source? We have enough already.

My entire HS was two stories as well. It's called overcrowding. More students enrolled than the school was built to house. Although we have a few shacks, I got it done. There really is NO way to change the five minute rule unless you can manage to get the entire student body to be late every day at each class which would probably never happen without a staged event. But then again, other schools seem to manage it, it would be fruitless. I remember my junior year, I had classes all over the place! First floor, Second Floor, Shacks - - times seven classes. You just have to be determined! I never wanted to go to Saturday detention. Wasn't happening! All I know, is I got through it for four years. :)
