CAN YOU SAVE ENERGY BY SURFING LESS GRAPHICALLY INTENSIVE WEBSITES?
Jul 2nd
Question by :
Can you save energy by surfing less graphically intensive websites?
For the average user, with a easy entry level desktop system will energy consumption be less if the user uses less graphically intensive sites, blocks Flash, and in general only taxes the system enough to get basic things done in the most simplistic way?

Q&A: ARE THERE ANY REASONS WHY A LARGER NUMBER OF BLADES WOULD BE MORE EFFICIENT ONA WIND TURBINE RATHER THAN LESS?
May 13th
Question by Isabella:
Are there any reasons why a more massive number of blades would be more efficient ona wind turbine rather than less?
For science, we did an experiment to determine whether 3, 5 or 7 blades were more efficient on a wind turbine. Our results showed that seven blades produced a higher voltage, and three the least.However, now we ahve to find theoretical background which would support this, and everything I find on theinternet states three is superior than more. does anyone know any benefits of having more blades?
Thank you.

LOVE THE ENERGY SAVING LIGHT BULBS, BUT A COUPLE OF HAVE EXPLODED AND/OR BURNED OUT IN LESS THAN A YEAR. WHY?
Sep 3rd
Question by Emily Dew:
Love the energy saving light bulbs, but a couple of have exploded and/or burned out in less than a year. Why?
Are these energy saving light bulbs more hazardous than they are worth? The exploding aspect worries me, though I cannot find much written about it. I am seriously considering replacing all of the ones in my home with traditional bulbs, but I know that is going to drive my electric bill up. What are your thoughts or experiences with these bulbs? Thanks!

ENERGY-SAVING FLUORESCENT LIGHT BULBS – DO THEY USE LESS ENERGY IF SWITCHED ON FOR ONLY A MINUTE?
Jul 12th
Question by keni:
Energy-saving fluorescent light bulbs – do they use less energy if switched on for only a minute?
I heard that they use a kick of energy when you first switch them on, then use a lot less while they stay on. Is the initial amount more than, state a normal 60w bulb? If so, what is the length of time where the two use the same amount of energy? This is not an exam question – I just want to know if it is worth using energy-saving bulbs where they are used frequently for short periods of time – cupboards, bathrooms etc.
