In 1978 when I received my MBA this was the major topic in our business school. At that point oil and gas prices were such that coal gasification and liquification plants were planned for North Dakota. In goes the lignite out comes natural gas and gasoline. OPEC recognized the challenge and oil prices fell. Only one gasification plant was built and my nephew, a 4.0 Chem Eng has worked their for almost 20 years. About 30 percent of the lignite fires the chemical process. Imagine if windmills were built and 100% of the lignite could be converted.
I'm sorry but I'm a cock eyed optimist and believe that if we depend on "that old Yankee Ingenuity" we can take control of our energy future and not leave it in the hands of OPEC et al.
BTW, if we were to build and give these windmills to third world countries they could enhance their economic futuries. That's what happened with cell phones. These countries didn't have to go through the telephone poles and outside wire plants to have phone service and Internet access.
