So what is your take on diesel fuel prices after 2020?

Here is the type of thing that I expect to help keep the price of diesel fuel under control: https://mobile-reuters-com.cdn.ampproject.org/v/s/mobile.reuters.com/article/amp/idUSKCN1LT0NQ?amp_js_v=a2&amp_gsa=1#amp_tf=From%20%251%24s&ampshare=https%3A%2F%2Fwww.reuters.com%2Farticle%2Fus-china-pollution-diesel%2Fchina-drawing-up-plans-to-take-polluting-diesel-trucks-off-the-road-source-idUSKCN1LT0NQ

For those that don't want to take the time to read the article China wants to replace diesel driven trucks with other types and has a goal of reducing diesel consumption by 20 million metric tons per year. They expect the project to commence by 2020 but don't give a target completion date. All the same, the direction is clear and I am sure that the same sort of thing will be happening in other countries, it is already happening here.
