55 Dutch professors signed a manifesto against application of shale gas in the Netherlands. From an environmental point of view there are only disadvantages and commercial advantages are questionable. According to the signatories shale is a hype, not interesting for Europe and certainly not for the Netherlands. To begin with, shale gas can only be found on much greater depths than in the US. Shale gas reserves in Europe are mainly located in Poland and France, 3.5 trillion m3 each (together 30% of US reserves). In contrast to the US, the soil is property of the state. In the US a farmer is approached with a financial incentive to give drillers access to his land. In Europe environmental regulations are much more strict than in the US, making shale gas exploitation less profitable. Shale gas exploration involves a highly toxic brew of benzene, mercury, arsenic and radon, that easily could end up in the ground water. For this reason France has forbidden shale gas and Poland seems to give up as well after disappointing results. For Holland it could mean that ecological damage will outweigh financial gains. The conclusion is that the Netherlands should concentrate on 16% target of renewable energy in 2020. That will be difficult enough.
