HOW LONG DOES IT TAKE A WIND TURBINE TO PAY FOR ITSELF?

admin — Sat, 04 Sep 2010 10:38:21 +0000

Question by BigDavez:
How long does it take a wind turbine to pay for itself?
Just an average size wind turbine in a wind farm.
Managed to find the answer myself, The average wind farm in the UK will pay back the energy used in its manufacture within six to eight months, this compares favourably with coal or nuclear power stations, which take about six months.

Answer by brijgupta46@yahoo.com
hi

The payback period depends on so many things i.e. cost of windmill, realisation per unit sale of electricity, mode of financing, location etc.

So people have different views. Variation is too massive 3 to 8 years.

WHAT IF AUSTRALIA DEPENDED ON SOLAR ENERGY?

admin — Sat, 04 Sep 2010 10:35:38 +0000

Question by scary-movie-lover:
What if australia depended on solar energy?
If australia began to use only solar energy to power the country, what do you think would happen? Also, what would happen to the other energy sources we are currently using and all the power lines? And how would we be able to make sure that important buildings like hospitals always have power?
Please answer, ideal question gets full points.

Answer by Peter
Your energy cost would skyrocket. You would still need the power lines to get power from a collection point to the cities. There is not enough surface area on a city office building to be able to collect enough solar energy to power the building. You will also be sitting in the dark a lot at night unless you can figure out a good way to store electricity on a grand scale.

Q&A: IS THE ENERGY-SAVING FLUORESCENT LIGHT BULB WHICH GIVES ME NEEDLESS TIPS ON Q&A REPRESENTATIVE OF DIM IDEAS?

Question by Master ß :
Is the energy-saving fluorescent light bulb which gives me needless tips on Q&A representative of dim ideas?
I mean, the original “bright” idea used a standard incandescent light bulb. Does Yahoo’s use of the energy-saving one mean that they anticipate people to be a tiny less bright when they participate in Yahoo Answers?

WHAT ARE THE PROS AND CONS OF WIND ENERGY?

admin — Fri, 03 Sep 2010 03:36:48 +0000

Question by MaryCheneysAccessory:
What are the pros and cons of wind energy?
There are a lot of wind farms going up in my area. The biggest con that I see from these generators is that they pollute the beauty of our mountain ridges here in Western Pennsylvania. Sure, I am all for energy independence, but I think we rush to solutions in this country. What are your thoughts?

——————————————

Answer by Scorpius59
We have those in Texas. I guess it depends on how close you live to them. At least they are quiet ! We need to use solar energy too. Probably a lot less land needed to “capture” it. There are some windmills out around Galveston. They are actually pretty out there on the beach !

HOW DO YOU CONNECT A SOLAR PANEL TO A MOTOR FROM AN RC CAR?

admin — Fri, 03 Sep 2010 03:35:18 +0000

Question by Tony Vo:
How do you connect a solar panel to a motor from an RC car?
Can anyone tell me how to connect a solar panel from a calculator to a motor from an RC car.

——————————————

Answer by dmoney_sc
Connecting them is not a problem: the solar cell has two leads or terminals, and so does the motor. The problem is that the panel from the calculator can’t supply very much current, and you need quite a bit for the motor. Also, the voltage is probably not more than 3 volts, and the motor needs probably six to twelve volts. If you have a voltmeter, check the output from the solar cell. You can get solar cells that will put out more current, but they will be larger than the ones used for calculators. Even with these, you will probably need several in series to get enough voltage for the motor.

LOVE THE ENERGY SAVING LIGHT BULBS, BUT A COUPLE OF HAVE EXPLODED AND/OR BURNED OUT IN LESS THAN A YEAR. WHY?

admin — Fri, 03 Sep 2010 00:33:16 +0000

Question by Emily Dew:
Love the energy saving light bulbs, but a couple of have exploded and/or burned out in less than a year. Why?
Are these energy saving light bulbs more hazardous than they are worth? The exploding aspect worries me, though I cannot find much written about it. I am seriously considering replacing all of the ones in my home with traditional bulbs, but I know that is going to drive my electric bill up. What are your thoughts or experiences with these bulbs? Thanks!

——————————————

Answer by in2alot
I’ve had the same thing happen after only a few months of use. The smoke that comes out of them when they burn out smells really bad too. I was wondering how these costly bulbs could do that too but I do not want to change because my bill went way down when I switched over.

HOW DO YOU CONNECT A SOLAR PANEL AND WIND GENERATOR IN PARALLEL?

admin — Wed, 01 Sep 2010 20:35:25 +0000

Question by oakwhiz:
How do you connect a solar panel and wind generator in parallel?
I have an ~18v solar panel and a ~15v wind turbine. Sometimes one generates more voltage than the other. How would I get both of them to charge one ~12v battery? I cannot just connect them in parallel with diodes, because in that case, only the higher voltage source gets used. Is there a special charge controller circuit that will do this?

——————————————

Answer by David
There are controllers to do this, but they are very expensive. Why not two batteries, one for each generator and a battery ‘change over’ switch’ on the output. When one battery is low switch to the other.
