effectively meaning in houses & cars & factories
& what will happen to oil producing countries when the world starts to depend on alternative energy ?

And other alternative renewable energy sources?

I just do not understand. If you do not like it please tell me why, or if you do please give me your opinion why others do not?

Be nice & thanks
I actually like wind turbines, they are beautiful and look like giant pinwheels!
Seriously Andy? There is a thing called batteries..that is like saying 'I am afraid my cell phone won't work if its not plugged into the wall!'

And the environmentalists totally wants alternative energy.

for my science class exam, I must assemble a portfolio of 4 types of renewable energy technologies, it cannot be solar or wind. I must explain whether the technologies are feasible or not. I must explain the pros & cons of utilizing this type of energy, whether it be environmental, economic, social or political. I can only find wind and solar and we're not allowed to use those. I know of like cranks and generators but I still need more. So can anyone give me any other good ideas for renewable energy technologies?........... I have until friday.

He mentioned ethanol, the production of which has been proven to be disastrous to the environment as well as damaging to food supplies.

He harped on electric cars which, again, create more pollution through the increased demand on power generation.

Wind & solar are useless outside of Jr High science projects.

So what mythological clean energy does he intend to throw away our money on?
How silly of me. Evidently everyone can have free power from wind or sun, we all just choose to pay ridiculous rates to burn fossil fuels.

Ethanol is a RENEWABLE fuel, but it is not a CLEAN energy source. This has been known for years. Do you people read anything other than fringe websites and propaganda?

As for Iowa... Not a single commercial wind farm operates without subsidies to stay afloat. They are economically unviable. In other words, the entire country is paying so Iowa can pretend wind energy is practical. It would be impossible to duplicate this nation wide.

From some of the Q & A on here that I have seen why does it only have to be one way?

Energy: Wind
Question: Can this type of energy generation be sustainable for generations to come (explain)?

Can you help me out & explain why?

topic, im looking to use .5" neodymium magnets to build a low resistance wind turbine, and i dont know how to determine what would be the best size of coil & diameter of wire to generate a given amount of electricity per rotation/etc...

can someone please help me? id be ever so greatful!!

If yes then , answer and i will make another post. Follow my Q & A's please.

I am working on the design & manufacture of small scale wind turbine. I need help in determining the size of model should i get manufactured for testing in the wind tunnel for its accuracy. What parameters are necessary while scaling down the actual blade design? In other words, what should be the ratio of model size to the internal cross-sectional area of wind tunnel?

Seems like this is the case. Why would Republicans act like Renewable Energy is bad? Is it because the Republican Party (and Democrats too) are serving the Petroleum & Nuclear Industries, because those industries are financing their campaigns? Why would you approach renewable energy like it is bad out of some displaced loyalty to your party? Have you ever really investigated RE for yourself?

I have searched online and I really can't find much. I know it was used in the early 20th century but I'm curious as to when society really became interested in it and started using it to power cities. (I know they use it a lot in Europe).
Thanks any help is appreciated. I'm working on an essay, I'm not asking you to do my home work but I can't find this & I was hoping someone might be a little more educated in this area? Thanks:)

I am trying to build a small wind turbine with enough power to light a 5 watt bulb.

Basically, I was planning on just connecting some 3in. fins to an electric motor from a hobby store (see http://www.radioshack.com/product/index.jsp?productId=2102828&cp=&sr=1&origkw=motor&kw=motor&parentPage=search ) and then hooking the electric motor up to a light bulb - will this work? Are there any issues that I have ignored?

Thanks!

i need to use solar &wind energy to run vechicles plz help me about how to store solar &wind energy . then convert this into mechanical energy

(coal,oil, & natural gas)

What are the short term benefits of increased r&d expenditures in energy versus acquiring another energy company?

the types of wind turbines i found was
industrial, agricultural, commercial, municipal, and residential
what is the difference between these?!
which wind turbine is used where.
I only know residential is for homes & its the smallest of all the wind turbines
but what about the others?
also compare their sizes please
thank you

PLEASE HELP!

This 10 second video is so shocking and awful that it even bothered me

what do you think about wind power?

All they have to do is increase their subsidies and incentives to companies in the renewable energy industry, create an easy to entry barrier with full Govt support, these Co.s will then invest the money in R&D and very soon there will be the advent of a new breakthrough in technology which will be cheaper than the current energy sources we have today.

This, in place of taxing CO2 and every molecule out there with out including H2O and O2.

What are the pro's & con's to renewable energies in general?

need materials list & setup instructions

I stumbled upon a site for a renewable energy, alternative energy plant in Ireland, it looked interesting & I was about to read it when I was interrupted. When I came back my wee bundle of joy had Sonic, (the obnoxious rodent) up on the screen & my Ireland article was gone. *so sad* Does anyone know what I was reading or referring to? Sorry my description is so vague.
