This is especially important with respect to climate change. The Stern Review was the report for the British government that laid out, proved, the case for doing something about climate change, probably the most important part of which is that we must use the cheapest method of doing said something. The logic is irrefutable: We humans do less of the more expensive things and more of the cheaper things. Therefore, if we use expensive methods of dealing with climate change, we’ll actually do less climate change prevention. If we use cheaper methods, then we’ll save the planet more, or save more of the planet.
Thus follows the rationale for our producing some part of wind turbines, even if not the blades, in Beijing rather than in Pittsburgh.
