      It is a shame they are allowed to burn off so much Natural Gas at the Bakken oil fields. The sat photo shows it compared to major cities at night.

        They have so much of it that they don't know what to do with it all. They've run out of room to store it.

          Why don't they run generators and put it on the grid? Better than just burning it off!

            A lot of our utility power in the US is generated by burning natural gas. Coal is used more though, and they should use more natural gas instead.

                  I attended a bio-fuels meeting at the UW Green Bay last Monday. At the meeting the final speaker approached the EPA regulations. There are so many restrictions laid forth by the EPA with the RFS and RINs it is taking several projects over a year to get permits. The speaker stated that she was only brushing the surface of the regulations to keep the topic within the time frame. (1 hour)

                    University of California Riverside now hosts a center for applied research into renewable natural gas. It is funded in part by SoCalGas with a matching donation from the South Coast Air Quality Management District (SCAQMD) and the National Center for Sustainable Transportation (NCST):
