Carl Sagan quotes about solar energy
The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground.”https://www.goodreads.com/
Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives.”“Carl Sagan (2011). “Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium”, p.104, Ballantine Books” When you think about this quote, the return to a world powered by solar energy seems inevitable.

They really do it. It doesn’t happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”https://everydaypower.com/carl-sagan
We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.”https://www.brainyquote.com/authors/carl-sagan-quotes
The burden of such a responsibility is heavy, especially on so weak and imperfect a species as ours, one with so unhappy a history.
