In the season opener, David Letterman travels to India, one of the most populous nation on earth. From expanding and repairing an inefficient energy grid to bringing electricity to more than 300 million people without power, the Indian government has committed to one of the most ambitious renewable energy plans on Earth. It's also pledging to double the amount of dirty coal the country already burns.
