so i believe this moment can be a turning point for the world. we ve shown that the world has both the will and the ability to take on this challenge. it won t be easy. progress won t always come quick. we cannot be complacent. while our generation will see some of the benefits of building a clean energy economy, jobs created, money saved, we may not live to see the full realization of our achievement, but that s okay. what matters is that today we can be more confident that this planet is going to be in better shape for the next generation, and that s what i care about. i imagine taking my grandkids, if i m lucky enough to have some, to the park some day and holding their hands and hearing their laughter and watching a quiet sunset, all the while knowing that our work today prevented an alternate future that could have been grim.
