With respect, jc96, you need to live without oil and it's products for a year. No more home heating oil, gasoline, diesel, aviation fuel, marine fuel, natural gas, emergency generators, plastics, Styrofoam, etc, etc - Google it - there are so many products. 
My point is that every one of oil's many products is a problem for an inventor that must be solved before we "go green". Those problems are absolutely NOT all solved yet. Green is a great idea but it is just not ready yet.
