I'm doing a science fair project on what would be better out of wind or solar for a school. I'm really stuck on righting up the method and i only have an hour to get it done!!! So if you could please help me with finishing the method it would be...
You don't need to write down any method, all you need to do is the practical part of the project and produce a conclusion/result.
The method is already written it's 1. through 7. Read it again, because it is how you'll carry out...
Approximate calculation of savings associated with operating a wind turbine.
I have a wind calculation to do. Here it is:
A site has an average annual mean wind speed of 8m/s and an annual standard deviation of 5m/s.
a) Calculate rough estimates of the Weibull parameters k and C and comment on...

I noticed that the formua for Kinetic Energy (KE=.5mv^2) results in Joules, and Joules can be converted into Watts/Kilowatts, which is the same unit of measure as the energy output of electric generators.
So my question is this:...
Your physics is correct. There will be an overall efficiency for the turbine, (any gearbox) and generator in converting kinetic energy into electrical power. I am not aware that it has a special name.
The efficiency, however, will...
I would like information about converters. I.E. where does their power supply come from? Are there different kinds of converters? Any Calculations that deal with their application in wind turbines? Any help or suggestions would be...
Robert, there are two basic types of wind turbines today, the home unit, and the utility unit. The home systems all use unregulated AC power made by turning permanent magnets through a winding. The AC power is rectified to DC in a control box on...
I was trying to put up an argument that wind energy is not feasible, but I just did some calculations that changed my mind. The new german wind turbine has a diameter of 112 meters. each one can power 4000 homes. There are approximately 160...
Calcs seem OK but here are practical issues:
1) Wind is a variable resource and even in areas where it is quite windy you can have days with no wind and others with to much wind which the turbine cannot handle due to stresses and...
Could a standard sized 3 bedroom home go "off the grid" by using solar panels on the roof and wind turbines in the backyard? Heating during winter could be produced by wood burning space heaters and cookstoves, and solar water heating...
The energy necessary to run a house in that area is certainly obtainable from wind and solar. But a more important factor than the location on the earth is how the home is situated on the site. If it's an existing home it can be retrofitted to...
Controversy over wind power statistics continues
When Full Fact published its original investigation into statistics on wind power backup costs used in a recent Civitas Report , we raised concerns that certain figures could have been mis-counted based on evidence from the original source from which the research was drawn.
Citivas responded to the concerns in full, initially raised by the RES group , by claiming that the original figures were likely to be underestimated themselves, and highlighted the acknowledged caveats concerning their data which they had originally made clear.
Continuing the dialogue, RES have produced a strongly-worded commentary on the Civitas response.
Kaine suggests Virginia explore wind power | Richmond Times-Dispatch
WASHINGTON -- In the wake of the oil spill in the Gulf of Mexico, could the answer for Virginia's offshore energy generation plans be blowing in the wind?
Former Gov. Timothy M. Kaine raised the possibility yesterday in a brief interview.
Kaine, chairman of the Democratic National Committee, said the recent spill in the gulf is cause for examining more closely the prospect of drilling for oil and gas off the commonwealth's coast.
Gov. Bob McDonnell's plan to drill to raise money for transportation received a further blow this week. A newly released Defense Department review concluded that drilling for oil and natural gas off the coast of Virginia could interfere with naval operations.
