"If we have a bottleneck on energy, in terms of volume not in terms of price, then we can have a bottleneck on production. And its is probably what has been happening by little steps since 1975. [...] And if we have an additional bottleneck on resources, then we will also get an additional bottleneck on production."
January 1, 1970
