SOME REALLY CHEAP & EFFECTIVE WAYS TO SAVE ENERGY?
Aug 31st
Question by TomLover:
Some really cheap & effective ways to save energy?
I have a few ways to save money and energy (use fluorescent bulbs, use rags instead of paper towels) but are there any more? And if so, what are some REALLY good ways of motivating people to do these things? Like, I know people will use fluorescent light bulbs because they last longer and they save a lot of money.

WITH CENTRAL AC, DOES IT SAVE MORE ELECTRICITY TO LEAVE THEM ON ALWAYS OR SET TO AUTO?
Aug 30th
Question by real_ki:
With Central AC, does it save more electricity to leave them on always or set to auto?
I have a central A/C unit in a two story house.
We usually set the temperature to 80F and set the fan to “Auto” which basically turn on the fan and the cooling when temperature goes above the set temperature.
There’s also “On” setting for the fan which will keep the fan running always and I assume the cooling too maybe?(or maybe the cooling is turned on when temperature goes above the set temperature).
Which will save more electricity? Setting the fan setting to “auto” or “on”?

Question by Steven:
How to adjust pitch on wind turbine blades?
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?
