Carl Sagan quotes about solar energy – WGSI Solar

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.”

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. Our current non renewable sources of energy that we depend on are essentially sun energy, stored solar power over many years and used today.

Few scientists now dispute that today’s soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000.”

Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.”

We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.”

In science it often happens that scientists say, ‘You know that’s a really good argument; my position is mistaken,’ and then they would actually change their minds and you never hear that old view from them again. 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.”

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.”

The burden of such a responsibility is heavy, especially on so weak and imperfect a species as ours, one with so unhappy a history. Nothing remotely like “completion” can be attempted without vastly more knowledge than we have today. But, perhaps, if our very existence is at stake, we will find ourselves able to rise to this supreme challenge.”

A galaxy is composed of gas and dust and stars – billions upon billions of stars. Every star may be a sun to someone.”
