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.

Today was interesting. I was helping my aunt move from the grandmother's old house. We were just finishing up and about to leave when suddenly, behind my mother's car, a sedan pulls up on the street that was intersecting the small, dead end road my mother's car was pulled into. Just so you know, this is an apartment complex so the roads are especially narrow. The man driving the car hopes out, red in the face before going back in like he was grabbing something. We saw hands form the back seat, almost like he was fighting with somebody before he closed his door and headed away from the car. We couldn't see him. Then, the person in the back seat, a woman, came over to my mother's car. She looked in distress and out of it, asking for a ride and help. She nearly got into my mother's car but my aunt quickly stopped that. She was asking for help still, going to say that she was scared. My aunt told her to go deeper into the complex but she shook her head before heading back to the man's car. My brother, 23, was nearly yelling to my mom to leave. Now. This was quite a situation and very testing for us. My brother, mother, and myself go into a heated debate on the way back to my aunt's old house. My mother and aunt said that they wanted to help the woman. Do something. Get her in the car and away from that man and even further. Possibly call the police if that was all they could do. My brother and uncle, who was actually in a parking spot right next to the man's car, said they wouldn't help her, no matter the circumstances. They would much rather not get into that situation, not knowing what he was capable of. Not only that, it wasn't their business. They weren't going to put themselves in a situation where they could possibly get hurt or worse. So, after all this, the question is raised for you, people of KW. If you saw a woman in distress asking for your help and you had now clue when that man was going to get back, what would you do?
