I always wonder what's the best way to assess environmental impact of the oil pipeline. Sure, it's going to leak at some point, and create a mess that may never get cleaned up. However, is it safer (or energy efficient) than carrying the oil on trains/trucks?
Pipelines are much safer than trains or trucks at delivering oil or LNG. That subject is not up for debate. The problem is that when you build this infrastructure, it comes along with long-term financial contracts. Which is to say, if you build it, you're gonna use it. As a result, it discourages investments in other energy infrastructure projects. Once the pipeline is in, we are stuck with it until it ages out of us…
Safer by what measure? Pipelines have fewer spills than trucks, but a truck spill is generally limited to one truck's worth of oil whereas a pipe can spill a huge amount. (I'm not sure where trains fit in. A train carries more oil than a truck, but train accidents won't always break every car).
