Dude, are you serious?!
Yes, I am. Let's take a look at your list.
1. Walk, Ride Your Bike and Take the Bus
- I've been walking to work since October 1995
Good for you. Nothing much to talk about it

2. More Fuel Efficient Internal Combustion Engines
Still runs on fossil fuel 100%.
3. Hybrids
Still runs on fossil fuel 100%. Just most efficient.
4. Plug-In Hybrids
Still runs on fossil fuel > 90 %. Where do you think the electricity come from? Wind, Solar, Hydro, Nuclear? I'll give it a 10%. I could be wrong about the percentage point, but that is not the point.
5. Electric Vehicles (too bad GM had to kill their version of it)
Same as #5
6. Biodiesel
You need more land than the whole country (take any country) to get enough biodiesel to be completely fossil fuel independent.
7. Vegetable Oil (it's not just for salads anymore)
You are kidding, right?
8. Ethanol (we're seeing alot more use of this in Canada these past few years)
Again, what is the source of ethanol? How can we have enough ethanol to replace our need for fossil fuel?
9. Cellulosic Ethanol
Same as #8
10. Hydrogen Fuel Cells
Now where does the hydrogen come from? Run a pipe to a hydrogen star? If you have to generate hydrogen here on earth we need to split water or some other kind of chemical reaction that costs more energy than what the hydrogen will give us. Thermodynamics, hello!
11. The Ideal Green Car - look it up, it's a plug in hybrid car with roof top solar that can also make use of Cellulosic Ethanol and BioDiesel
Solar, may be someday. Not with current technology and solar cell efficiency.
I try to temper my seriousness with a $hitload of "smart a$$-ness"!
I see that
No offence, but it is very easy to get carried away.
All I am saying is that there are no technologies with exception of nuclear power that can realistically get us out of the woods.
