On Monday, the leaders of the G7 made clear that our future will strongly be based on clean energy. In their meeting in the Bavarian Alps, the world’s largest industrialized economies pledged to dramatically reduce or altogether eliminate greenhouse gas emissions by the end of the century, a commitment likely to be solidified in December in Paris. As pressure builds for the world economy to expedite a shift away from coal, oil, and natural gas in order to avert the effects of climate change, attention will turn to cleaner energy, such as wind, solar, and hydro power. This should be applauded. But we should not kid ourselves that clean energy will be completely free of challenges. Despite the many positive elements that renewable energy can bring to these countries, the construction and operation of these major projects does not render them immune from the challenges of implementation.
