I was wondering how much electricity does wind turbine and a solar panel give out and how much does each cost.
and also how much does each one cost.
I’m thinking about buying one. But I only need one that can run a computer set up and possibly some lights and a phone
Please keep the answers simple because I don’t know much about this stuff..

By looking at your question I am making the assumption that you are not planning on being on the grid. If that is the case then you would need a couple of solar panels, batteries(for night time and cloudy days) and an inverter to change the dc current to ac if the computer is a desktop. If you have a laptop which uses less energy and which runs off a battery you may be able to save some money on the inverter by not even needing one. Lighting can easily be done on 12 volt like the solar panels put out, just look at every car on the road. The phone will probably be able to be used off battery power also.
In my opinion a wind turbine would probably be overkill for what you are trying to do, I have one and it runs my whole house as part of a grid tied system so when it is calm for a week straight the power grid feeds my house and when the wind blows every day for a week my meter runs backwards to make up for the calm times.
I would guess if you did the work yourself with new parts it should cost less than $5000 and if you are very creative and thrifty you can probably do it for a thousand dollars.
There are also prepackaged systems that you just assemble. If you go to http://www.bergey.com click on value packages and look at the 1.2kw hybrid system. It has a small wind turbine and solar panels with inverter and backup batteries for about $8,000. There are thousands of web sites that sell solar setups so check around before buying from anyone.
Good luck going green!

Savage above is talking about Solar windturbine farm run by governments. It is partially true. It does not break down often as he/she says. They do wind pattern and do engineering studies before putting up the tower. Like any technology, they have improved tremendously over the years.
Governments spend about $2 to $3Billion for about 300 MW.
China and India are far ahead in this than the rest of the world.
To answer your Q: To put one up on your backyard, be prepared to spend upto $30,000 for about 500KW. It is expensive but………(there is always a but, right?)…..
You recoup your costs by pumping it back into the grid the excess power that you do not use (your power meter will run backwards - you need your power company’s approval). Pay back period will depend on the cost, the capacity of your turbine etc..
Check with your local utility company. They actually encourage this and they even offer incentive to put one up.

Don’t believe them. Solar power is good and will help save CO2 emissions, but it will probably never pay for itself.
First, your solar panels only produce power about 35% of the time at peak sun times, and produce nothing much on cloudy days and at night.Because of this, you must at least have a battery bank for storage, and sufficient numbers of panels to produce the extra power needed to store. You then need a charge controller that goes between the panels and the battery bank. You also need a rectifier/controller that converts the DC power to AC and controls voltage and the rate of discharge. For a fairly small system this will cost $20,000-$30,000. It will produce enough to power a few lights, TV, and maybe a refrigerator if it is not frostless. You will want either the grid or a generator for back up when you have a couple days of cloudy / rainy weather.
Calculate it out. Since none of the equipment will last much more than 20 years, and just the cost of your money will be about $80/month, there is no way it is cost effective.
Just do it because it is cool and reduces pollution. Don’t do it to save money. You most likely will not. If one could, every home in Phoenix or Las Vegas would have them. Check it out. Very few there where it is the most optimum weather for it.

I bought a small panel for $40 a few years ago. It plugs into my cig. lighter in my vehicle to charge the battery. This paid for itself the first use when I left the lights on by mistake and had a dead battery. I also don’t need to use power to run the alternator, thus saving a little gas, can listen to the radio even when the vehicle isn’t running and can charge up my phone / computer from the cig. lighter connection. I am making a small wind turbine out of a box fan blade and some other free parts that can charge my battery if its windy but not sunny.
You can buy a small wind generator (like they have on boats) for $900 or so, or a solar panel for maybe $200 that would charge up some batteries ($300?) that could run your required equipment, depending on how much you want to use it and the frequency of wind or sun where you are.

Today there are plenty of DIY guides that teach a novice DIYer design solar panels at a minimal cost. These guides offer thorough instructions and simple to understand schematics. As a result, practically anybody can design one. Though it may look quite scary to some, the manufacturers of these educational kits simplify the task a lot. Few of them even have an educational video that shows you how to do the construction, thus simplifying it more.

alright. my dad works for the power company here so trust me. ik. ok. wind and solar are SUPER exspenvive. and wind only is workin 17% of the time. the rest of the time they r broken and not producing elctricity and solar is expensive and un reliable. we need to go nueclear. its clean and safe now. its our only hope.

Hope it helps & Good luck!!!

A few of the potential disadvantages of solar power include cost and location. If you or your neighbors have mature trees that shade your roof, solar power panels may be difficult. Like many of the previous posts stated, solar power panels can be costly, ranging from $30,000 to $50,000. After this initial investment, however, they produce electricity for the life of your home. Not all roofs can bear the additional weight of the panels. Depending on your location, the panels must be cleared of dirt, snow, and bird droppings to maximize their potential.
The ideal conditions for wind power at your home is a minimum of an acre of property and at least 10 feet higher than anything within 300 feet, such as trees and power lines. If you decide to build a stand-alone wind-energy system for your home—which can cost up to $25,000 installed—monitor the wind on your property for at least one year before construction. Experts say adequate wind speed must be at least 16 miles per hour.
Here are the pros of wind energy, taken from Natural Home magazine. Wind energy can lower electricity bills by 50-90 percent. With rising natural gas prices, wind power is cheaper than conventional because its prices remain fixed. Xcel Energy reports that in fall 2005—when natural gas prices soared—homes using 100 percent Windsource energy saved an average of $10 per month over a similar home using conventional power. Federal incentives are available, http://www.dsireusa.org
Natural Home magazine says that the disadvantages are cost, location and zoning regulations. There are no federal tax credits for homes with wind systems. Because the wind is unpredictable, rooftop turbines are less productive than towers. Your neighbors my protest the turbines and zoning regulations may restrict the installing all together. The cost is extreme, $35,000 to $40,000 depending on the location.
