The document discusses the need to transition away from fossil fuels to more sustainable energy sources in order to address climate change. It outlines current trends showing that over 80% of energy comes from damaging fossil fuels. It then provides examples of solutions that already exist, such as increasing use of wind, solar and other renewable energy sources, improving energy efficiency, and implementing a smart grid. While the transition will be difficult and costly, it will also create jobs and make communities healthier while protecting the planet for future generations.
