Each year, scientists issue ever more dire warnings about the progress of climate change and its disastrous impact on humanity and all life on earth, and for many Americans, combating this destructive trend is a leading priority. One of the most important steps is to reduce dependence on “dirty energy” sources, like fossil fuels, and to shift to using renewable energy. This issue of The Reference Shelf looks at the renewable energy debate and draws from the press and politics to gather opinions about subjects like wind and wave energy, the future of solar energy, the challenge of designing eco-friendly energy storage, and the difficulties in tackling fossil fuel dominance in the energy industry.
