Electrical distribution / Power systems questions!?
Hello everyone,
I’m studying electricity in school, but I still don’t have a firm grasp on electrical power systems and was hoping for some help. I have four main questions. Anyone working in power systems, please share your knowledge!
1. How do each of the various generation schemes (coal / steam turbine, wind farm, nuclear plants, etc) output power at exactly 60Hz? I understand the basics of how a electrical generator works, but I don’t understand how they stabilized the output frequency to exactly 60Hz.
2. How do multiple generation points in the system synchronize their outputs to each other? How do all the different power plants and such dump power onto the grid together at the same phase?
3. I guess I don’t understand the grid itself overly well. Could anyone explain the concept of the power grid? (for example, is it like multiple net contributors of power (power plants, etc) each acting similiar to batteries in parallel?
4. What happens to excess (unused) power? If a particular system has three 250MW power plants, but the neighborhoods they power only use up 600MW, what happens to the extra unused 150MW? I’ve heard that people monitor the power input/output and “adjust” the power output from the plants to match the consumers’ usage. Is this true, and if so, how is this done? (shutting off generators, running them more slowly, etc). Also, if this is the case, what is done for power generation sources that cannot be human controlled (say, a wind farm; when the wind blows, it turns)?
Thanks in advance.

When Is Geothermal energy easily accessible to the general public?
I cant find this anywhere?
I understand that its there all the time, but i need a source
so does anybody know?
Plus your source.
Thank You!

UFO Hits Wind Turbine…?
Has anyone heard about this?
Over in the UK a wind turbine blade was smashed at 4:00 am. The turbine which is used to generate electric is 290 feet off the ground and the blade is 65 feet long. There are no reports of aircraft hitting it and the wind isn’t strong enough to do that kind of damage.
I’ll admit I think the vast majority of UFO cases can be explained but if this really happened then that is just weird and honestly scary.
Here is link to the Sun Newspaper. In the right corner there is picture of the turbine.

Let me know what you think. Thanks.
Actually I put the wrong link, here’s the right one.

Are the people who are saying Obama blew up the oil pipeline the same ones?
who said Bush and Cheney blew up the Twin Towers? Don’t you just love conspiracy nuts?

how do you dye your hair white with hydrogen peroxide?
or at least get it to the lightest phase and then have a good dye. I am really health so I don’t like to use a lot of chemicals that are in commercial products that are extremely bad for you, so if anyone knows any safe alternatives i would really appreciate it!
