Your Questions About Renewable Energy Content
Robert asks…
Doing a school project on environmental change, need a tiny bit of help?
My 3 solutions for cutting carbon dioxide emissions are:
-new biofuels (not derived from food)
-Improvements to wind, solar, or any renewable sources of energy (i have yet to pick 1 specific one)
-Green building
Are there any sites or organizations that are specifically dedicated to one of the solutions?
admin answers:
– There are several proposals for non-plant bio-fuels, switchgrass is one and ethanol producing algae are another.
One resource I would tap into if I were you would be Wired Magazine. They are a reputable source and could be of direct us to you as well as providing interviews from experts that you could then research. Just go to the site and type in biofuels into the search

– One of my favorite improvements to wind energy is found this article I read about improving the design of the rotor blades themselves. It is pretty interesting and the rest of the site should be useful to you as well.

– The US Green Buildings Council is a great authority on green buildings and have developed a set of standards to rate buildings

Hope that helps.
Joseph asks…
What is the product of adding ethanol to petrol?
ok so I’m pretty sure that the equation goes:
C2H5OH + C8H18 —> C10H23OH
I need this for a chemistry assignment I’m doing but Im wondering if I’m completely off the mark here… Im looking for what the product of blending ethanol with petrol to about a 20% content would yeild, bear in mind this is a year/grade 12 thing so it doesnt require a super complicated answer.

Woah
yes
you are completely completely off the mark. That chemical reaction doesn’t happen, you’ll learn why in college level organic chemistry.
The mixing of ethanol with gasoline doesn’t cause a chemical change, its just a mixture. Its like putting water into gasoline– its still gasoline and water. But at least the ethanol burns!
The goal is to have “renewable” ethanol which is derived from corn or sugar, used instead of unrenewable gasoline.
And its great, until you realize that it takes more energy to grow the corn and harvest it and turn it into ethanol than you get out of the gasoline.
If you want to stand apart from your classmates, argue AGAINST unfail ethanol subsidies which cause food prices to go through the roof while people around the world starve!
