Solar Power
Solar powered devices get thier energy from the sun. The sun produces heat and light energy that can be converted into electricity to run many different products. This is probably the most commonly known source of energy. It has been around since the ancient Greeks discovered that the sun was an excellent source of more than just light! There are many products that are solar powered including things as small as calculators and things as large as homes! Solar energy is a very efficient way to supply energy and power to a home.
Wind Power
Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines. This is the cleanest way to obtain energy because it reduces greenhouse gas emissions by not using fuel or other sources of oil to be produced. The most commonly seen turbines include three arms, which continue to spin around, creating useful energy. Wind energy is a very efficient way to run a smaller area, but when used to supply a larger demand, it gets pretty costly!
Hydro Power
Hydropower or "hydraulic power" is the force or energy of moving water. Before the widespread of today's commercial electrical companies, hydropower was the main source of energy around the world. Some of the most common uses were used for irrigation, and operation of various machines, such as watermills, textile machines, and sawmills. By the energy produced by the water, a trompe is able to be put into use. This is a tool that produces compressed air from falling water, which could then be used to power other machinery at a distance from the water. Using hydropower is another really clean way to produce energy.
Tidal Power
Tidal power, or tidal energy, is a form of hydropower that uses the movements of water waves to produce energy. It is not as widely used as the other forms of power and energy, but it is a lot more predictable than any of the others. This kind of power has been being used in Europe for hundreds of years, the energy it produces is used in grain mills to grind the grain.
All of these types of energy are very efficient and easy to use. I think that in the future, we will be seeing a lot more solar powered objects because using solar power is a lot more Earth friendly. Plus, without all of that gas being used, maybe the price of it will go down!! (wishful thinking right, ya i know)

Oh Sarall,
What a great post:) I like your intro, it was cute. I like how you talked about each power. It was very clear and concise. Way to go!

p.s Stop poking me;)
Way to go Hailey. 1 What's with the "Solar PowerSolar powered" in the begining of the second paragraph? 2 You did it again, "Wind PowerWind power", whats going on in your brain? 3 Jeez another one, "Hydro PowerHydropower" are you feeling ok? 4 Other than those brain farts, it was pretty good, keep up the fantastical work.

SarahAnn,
Great job this week. I had no idea of all the uses of Hydropower. I really liked how descriptive you were when discussing wind power. I really agree with you that we need to consider all of these to reduce the cost of gasoline. Maybe there could be a possibility to help reduce how dependent we are on gas and start using other forms of energy to run transportation.

you have done a very great job on this weeks post. i enjoyed reading about the different kinds of energy that we can use over and over again. i wonder what kinds of energy we will come up with in the future that we can recycle. i can't wait to read your next topic, next week.
Beautifully done yet again, jolly good! I love the way you introduce the topics, providing a more intriguing onset. You have simple, easy to read explanations of each term as well. It is a shame that it will cost too much to actually carry out these technologies. Too bad our economy sucks or maybe we could go green. Not sure if global warming actually matters. ;)
Fabuoulsy yours,
Megan
sorry sarahann. i called you hailey. :( oops. i still love you! :)
SarahAnn, you did a fantastic job on your intro paragraph. You picked the other topics that I didn't, so I really enjoyed reading your post. You included some facts in your post this week that were very interesting. Your post was just absolutely wonderful this week.
Rachel
Well done there Ann of Sarah. You had one of the best posts i was forced to read. It was load with info. I also enjoyed your intro.

SarahAnn,
Your introduction was very interesting and was a great way to get everyone's attention. It was really intriguing how you included the history of solar power relating to the Greeks. Your information on hydro power and the examples you included were very educational. I really enjoyed your opinion at the end of your post because it added value to the content.

Sarhann, i really liked the way your post was set up. i liked how you talked about all of the used of these natural resources. great job of giving defitions and detail. i really liked really this, it was an easy read but interesting!
Sarall (i'm going to steal keri's name for you cuz i like it :)
Well it was interesting how you put all the different types in one huge paragraph. Way to make it hard to read. jk I liked it cuz it doesn't let people skim read you kinda have to read the whole thing ;) You just want people to read your post.
