Repower America: 100% clean electricity within 10 years

Its website says:

Repower America is the bold clean energy plan to "repower" our country with 100% clean electricity within 10 years. By making buildings and homes more efficient, ramping up renewable energy generation, constructing a unified national smart grid, and transitioning to clean and affordable plug-in cars, we can address our country's economic and national security challenges — all while making huge strides to solve the climate crisis.

Is it possible? Yes, it is. Will we actually do it? I'm less certain about that. John F. Kennedy famously said in 1962, "We choose to go to the moon. We choose to go to the moon in this decade." And in seven years, we did. We implemented new technologies and knowledge at a tremendous pace to support a vision, and we pulled it off. What motivated us? What was at the root of that amazing achievement? We were afraid of the Soviet Union conquering space, and then using space to conquer us. In the same speech, Kennedy said, "Only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war." Repower America uses this line of reasoning in their pitch, citing "our country's economic and national security challenges" as primary motivators, and noting that it can help solve "the climate crisis" to boot. Should nationalism be a motivator for renewable energy? We don't collectively seem to be afraid of the hellish potential of climate change (yet) to take unified, swift, and sweeping action... and it's not as if they're promoting jingoism, right? And it is unavoidably political after all, isn't it? The Apollo program — not including Mercury, Gemini, and other preceding programs — cost us 25 billion. Adjusted for inflation, that's about 145 billion. The Iraq war has so far cost us 680 billion. The war in Afghanistan, over 190 billion. What's the long-term return-on-investment to America of those expenditures? And what would it be for ending our reliance on non-renewable energy?
