The choice is not between a pipeline versus trucks/trains. The choice is between a pipeline versus no pipeline. We don't need the oil. We need more solar, more wind, the costs of which are rapidly coming down and in some places are better than coal/gas. And improvement in battery technology and smart power grids are rapidly removing the issue of dark/calm periods. So bugger the oil and the pipeline.
This is, once again, simply not true.
As I have explained before, when wind and solar is only supplying 1 or 2 percent of the grid, the inherent unreliability of that power source is not priced into the the market. This is because on the 70+% of the days the plants produce no energy, the lack of energy can be made up for by the other base load power sources. However, as soon as you reach around 8% dependence, an amount not easily made up for by the other base-load sources, overall electricity prices start increasing due to less energy being supplied then what is in demand because of the unreliable nature of wind/solar. At this point, since wind/solar do not produce energy 70+% of the time, which can not be predicted, you have less energy then you need since other sources can not make up the loss, and overall prices increase. Prices continue to increase more and more the further after this threshold you move.
There are other factors at play as well, namely that wind and solar produce electricity at non-peak times when electricity is in general cheaper anyway. (Think of non-peak rail tickets.) Then, since wind and solar can not be turned off at this time, you often end up producing more then what you need at non-peak times, dropping prices even more. Keeping with the rail example, this would be like adding 50% more seats on non-peak trains only, lowering those non-peak tickets, and then bragging about how you lowered overall train ticket prices. So the idea that wind/solar are cheap is really only true during times when you don't need a lot of electricity anyway. However, during peak times, wind and solar often can not even compete with base load sources.
This has been shown by the fact that everywhere that relies on a sizable portion of wind and solar has electricity prices higher then the overall average. Germany pays roughly 60% more then France and has a much higher carbon footprint. California pays 30% more for electricity then the national average, and, now it seems, is returning to the era of rolling blackouts. How fun!
Solar and wind is a pipe dream. If you disagree please provide me with an place that has cheaper prices with wind/solar supplying at least 8% of the energy.
Furthermore, battery power will never be a viable option. This is because when you use a battery, you are adding two additional power conversions into the grid. Namely, you will need to covert kinetic energy into static energy when storing the power in the battery, and then convert they stored static energy back into kinetic energy. In both cases, you are loosing energy, decreasing your supply and thus increasing cost. It is much more efficient to have a powered grid supplying the exact amount of power needed at anyone time so as to avoid any power conversions.
Here is a more detail explination of the issue with wind and solar.
On the economics of wind and solar powerNow, yes, it is true Hirth paints a rosier picture then his 2013 paper on wind and solar, but it is still not nearly as rosy as many would like it to be. Fact is, wind and solar will only ever produce a fraction of energy, and the more we rely on it, the higher the cost will be.
