Pipelines are the cheapest way to move any liquid, yes there are a lot of pipelines in the US now, but they are all maxed out for capacity, from natural gas to the liquids pipelines, our need for energy is much greater than it was 50 years ago when most of the pipelines were built, shortages are all the time. Most home owners or city people don't know or realize anything is shorted, that's because they take priority over anything else. The fall of 19 was a good example, all farmers were shut off and shut down due the shortage of LP gas, anyone on natural gas was shut off as well, to keep the cities fed and everyone's home warm. This isn't new by any means and its not an isolated incidence either, it happens all the time.
Most pipelines were built over 50 years ago, and yet people seem to think for some reason our energy consumption has stayed the same or gone down, it hasn't its gone up, way up, farmers yields have increased three fold or more in the last half century, that many more bushels to dry, more homes have gone up, more to heat, cities have expanded, also more to heat and the list just continues, yet pipelines don't or can't expand, so its trucked instead or worse yet, by rail.
As a contractor, the whole concept of pipelines is a mixed one, first I hate them and having to deal with and dig around them all the time is beyond a pain, yet I need to fuel they bring near me so I can run my machines, heat my house and dry my crops.
There are two sides to the keystone pipeline, some hate it, some love it depending on which side your on, most states were up for the revenue they'd get off it via the taxes it provided and nothing for expenses verses trucking it all over the roads, next is, before it gets to the gulf, it first has to go through the US, meaning before anything can be exported, its on US soil first and controlled by the US, so if we need the oil 50 years from now, it won't be exported at all or ever. Some feel its like putting a pipeline through your property up to your house and it ends there and can then be pumped out...........or your getting it first before any is pumped out kind of thinking, if its abandoned and not pumping Canadian oil, in the future it can move other liquids, which are badly needed across the US even though most don't know it or realize it. Jobs when building and once done will still be created and every hour it will generate revenue no matter what. So John is partly right, basically it shouldn't go across the US to export someone else's oil, but on the other hand, who in their right mind would ever pump their product via another country for export that the other country controls the spigot end so to speak? How about it, every drop of oil exported from the middle east would first go through the United States before its put onto any ship or vessel, I think it would sure be good for the US and I don't think we'd be having so many issues dealing with everyone over there either, but that's just my opinion, sure others have far different one's.
