How much do these wind turbines cost and how long does it take for one to begin making “free” electricity?


——————————————

Answer by Chester
it will cost about $ 150 and how long??well it depends if you install it fast and might be around 3-4 days you can genertae your own free electricity..

What are the short and long term effects of solar energy?
i am doing a report on solar energy and need a tiny help.
if you could leave me the website you got the answer from that would be great!! Thanks For your help!! :0D

Answer by SolarBerg
There are tons of sites. Here is probably one of the best:

http://www.nrel.gov/solar/

This is the goverments NREL site, for National Renewable Energy Lab. Its pretty technical. For more laymen terms and information try this:

http://spheralsolar.com/solarpowerlearningcenter.html

They sell stuff but the learning center is free.

Hope this helps

How long can I be away from my personal before I should just shut it off to save energy?
I know turning it on and off too much is not very good for the computer, but when is it superior energy wise to turn it off? (This is for a laptop and a desktop.)


——————————————

Answer by arty1987
put it on standby if not away for long

Answer by easymover00
A personal doesnt use up that much power actually, you leave it on for a full month, cost you maybe $ 2.00 in power. I never turn mine off, unless I need to restart because of updates or some other reason. but you can just put it on standby.

Answer by Rich P.
Actually, if you set your computer’s settings properly, it will go into an energy saving mode on its own, and will save you money that way. Another thing is that why shutting down and booting it, you are actually using more power to do that then letting it go into power save mode. If you have a personal that is cooled properly, you can leave it on indefinatly, unless it absolutly need to be shut down for maintainence procedures, otherwise if your personal is running hot, shutting it down is perhaps ideal once a week to prevent the CPU and other parts from over heating and wearing out. Another plus of leaving the personal on is that the personal then maintains a constant temperature and thus you have less thermal xyxling and your parts last longer.

——————————————

Answer by aviophage
Solar energy is not measured in megatons.

A megaton is the equivalent effect in a nuclear explosion of one million tons of trinutrotoluene exploding simultaneously in a chemical explosion.

Explosive force does not measure efficiently in terms of heat or light energy in radiant form as in the case of insolation per unit area.

Better speak to your teacher. Sounds like some basic instruction in matter, energy, and units of measure is called for.

Good luck.

Answer by anobium625
“A 1 megaton bomb produces about 4 1015 J.”

I do not know what the space is supposed to mean here. The energy released by the bomb would be many orders of magnitude more massive than 41,015 J.

Turning lights on and off uses energy, but how long should they be off in order to save energy?
When I was younger, my mom always yelled at me for turning the lights on and off rapidly, but i suppose i never understood why, and to this day still. If I use a light for 5 mins and turn it off leave for 10 mins and come back to turn it on for 5 more, am i using more energy than keeping it on for 20 mins straight? Thanks!

hopefully information on Incandescent, CFL, and Fluorescent lights could be explained to me! thanks!

Answer by john
Install movement sensors in each room to operate the lights to turn them on and off when no one is in the room. It cuts way down on your bill.

Answer by whsgreenmom
Basically any time you turn it off you are saving energy. CFL’s use about .2 watts more for about 10 seconds when they are turned on, so even leaving the room for a minute or 2 you would use more energy leaving them on. Many people state that you wear out the bulbs quicker if you turn them off and on too frequently, but I have not seen a difference in any of the bulbs I have.

Answer by Harmony
The Mythbusters actually covered this myth! Turning on a light does indeed use more energy than a light bulb that is continually burning, but only for a fraction of a second, and it is minimal. Even if you are going to leave the room for a minute, if you turn off the light you will save energy. If you do that each day for a year, you would save enough energy as a light bulb that has been on needlessly for over five hours!

Answer by DrAnders_pHd
Aww no fun. You put the answer in the question :(
(23 years but that 1 Mton is the equivalent of 1.1 terawatthours of electricity. And that is ALOT. Divided by 23 you still get 48 Gwh/year).

Please tell me how wind energy is generated and how long will it last on earth. Also tell me 4-6 advantages of using it. THANK YOU SO MUCH.
Why is it a renewable resource?


——————————————

Answer by Honey
it’s generated by wind mills and it is a renewable resource so it will last forever

Answer by sweetlilangel_6
I believe wind energy is generated by windmills. advantages well
1.it saves our fossil fuels
2. it’s more cost efficent
3. it doesn’t pollute the air
4. it is renewable

Answer by Dane M
wind energy is not generated by windmills, its harvested, or harnessed by the windmill. If this is a quiz or test question, and you have a tricky teacher, watch out, he could be trying to be sly.

How long does it take to charge a 12v deep cycle battery with a 10 watt solar panel?
I want to also know if the 10 watt rating on the solar panel is 10 watts per day or is it constantly adding 10 watts? Is there a time which the 10 watts is being added like 10 watts per second or 10 watts per minute and so on?


——————————————

Answer by JOHNNIE B
Normal power is measured in kilo watts per hour. It sounds like 10 watts would be very small to do anything.

Answer by Annon
Watts is a measure of energy per second. IE joules per second. 10 watts = 10 joules/second

Car battery capacities will be measured in mAH (milli-Amp hours)
capacities vary greatly even though they will still take a fair while to get charged by such a little power charger.

Answer by jleblanc42
It will put out 10 watts in full sunlight at noon, less at other times of the day. That means 0.83 amps, so just divide the battery capacity (in amp-hours) by 0.8 and you will get an approximate charging time under full sun.
