Lens, I have been hitting gas stations for 50 years.  They were there, they were dependable, and they were reasonably cheap for the fuel and service they provided.  I am all for the change to EV's, which will take time and cost me about $700 to set up a 220v plug/charging station in my garage. 

I could never complain about the job the oil industry has done to improve the growth and opportunity to get ahead in this USA.  In essence drilling is mining and is fairly labor intensive providing jobs for all sorts of support and technical industries not to mention the high paying jobs to refine and process petroleum into finished products.  They may have been forced to clean their act up, but they have done so and should continue, but to brush aside a great industry that has made this country great is hogwash.  You protest too much about things that will surely change in time without your or anyone's pushing. Canada and the US owe many of the best jobs still available to the oil and chemical industry.  I hope so, but I am not so confident the EESU will provide the number of jobs we need for some time.  To be cost effective, the EESU will likely be built with considerable automation, which does not put people to work.  I assume the jobs will come from the new products that will be made using this device.  Let us hope so anyway.  Then DW can truly save future generations of our young folks, provide manufacturing jobs and save the USA.
