Today, Hillary and I were honored to be on the South Side of Chicago to celebrate the opening of the Obama Presidential Center. The Obama Center tells the story of eight years of progress, and is a stirring reminder of the powerโand responsibilityโwe have as citizens shape a better future.
Congratulations, Barack and Michelle, on this extraordinary accomplishment!
Long before modern nuclear technology, nature operated nuclear reactors in the belly of the Earth.
These reactors are part of our planet's natural story...the story we harness to power a cleaner future.
