I am doing a science fair project in which I will measure the energy output of a wind turbine whose blades are tilted at various angles. How can I change the pitch for each blade equally, and without having to create separate pieces each time I want to change angle measure? Is there a single piece which I can install, then rotate to change the pitch?

im all about the eco-friendly stuff. but like whats the difference between regular makeup and eco-friendly makeup? like is it the minerals or something? i want to get some, but what does it do to help the earth and environment or does it even help it at all?
where can i buy some eco-friendly makeup?

I want to start using solar energy on a small scale and eventually start doing bigger and better things with it. The first thing I have in mind is getting solar energy to power two small fish tanks I have. I am just curious if anyone can point me in the right direction because I don’t even know where to begin. I am sure I can find the products I will need but I don’t know what I will need and how complicated the setup will be. Any help would be appreciated. Thanks.

Hey,

I was wondering if you could recommend any top performing Green Energy funds.

Any advice is appreciated…!

Thanks so much,

If global warming is already causing an increase in the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados and other consequences include higher or lower agricultural yields, glacial retreat, reduced summer stream flows, species extinctions and increases in the ranges of disease vectors already what else can come next?

My grandfather is getting ready to go through chemotherapy to kill off the tumor that is wrapping itself around his spinal column due to multiple myeloma. Can anyone help me? Time is short, and my family and I are desperate.

I want a hybrid but don’t know what kind to get !

have just heard about an electric furnace, and I am wondering if it works like a natural gas furnace? Can a person take out their old natural gas furnace and put in an electric one? I am wanting to go eco-friendly and as all of our electricity is by hydro power I think electric is the way to go instead of the natural gas furnace I have now.

Well the question says it all really, thanks x
p.s renewable energy resources are things like solar energy, tidal energy etc.
