A Quote by Carl Sagan

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. - Dr. Carl Sagan
The transition from coal, oil, and gas to wind, solar, and geothermal energy is well under way. In the old economy, energy was produced by burning something - oil, coal, or natural gas - leading to the carbon emissions that have come to define our economy. The new energy economy harnesses the energy in wind, the energy coming from the sun, and heat from within the earth itself.
Since 1850, burning of fossil fuels, coal, oil and natural gas has increased 100 times to produce energy as the world has industrialized to serve the world's more than 6 billion and growing population.
The real requirement, if we are to avoid runaway global warming, is probably 80% by 2030, and almost no burning whatever of fossil fuels (coal, gas and oil) by 2050.
It is to them [fossils] alone that we owe the commencement of even a Theory of the Earth ... By them we are enabled to ascertain, with the utmost certainty, that our earth has not always been covered over by the same external crust, because we are thoroughly assured that the organized bodies to which these fossil remains belong must have lived upon the surface before they came to be buried, as they now are, at a great depth.
It is sunlight in modified form which turns all the windmills and water wheels and the machinery which they drive. It is the energy derived from coal and petroleum (fossil sunlight) which propels our steam and gas engines, our locomotives and automobiles. ... Food is simply sunlight in cold storage.
Of course methane is a fossil fuel, but as long as it is burned efficiently and fugitive emissions of methane gas are minimised, it is a less harmful fossil fuel than coal and oil and is an important way-station on the global journey towards low-carbon energy.
To restore our inflamed atmosphere to a hospitable state requires nothing less than rewiring the entire globe - and replace every oil-burning furnace, every gasoline-burning car, every coal-burning generating plant, with renewable, climate-friendly energy sources. The earth's fossil fuel resources have blessed us with a level of prosperity and abundance unimaginable a century ago. Today they are propelling us forward into a century of disintegration.
There has always been enough fossil fuels to power human civilization for hundreds and perhaps thousands of years, and nuclear energy is effectively infinite.
The U.K. government faces three choices to deal with carbon-heavy fossil fuels: force people to stop using them immediately; facilitate a rapid transition from fossil fuels to renewable energy; or hope business-as-usual market forces solve our problem for us.
The true cost of the pollution that is being dumped into the atmosphere and manifests itself in our sick children dealing with asthma or older folks dealing with heart and lung disease from the pollutions created by the burning of these fossil fuels, may not be reflected in the prices of fossil fuels, but that does not mean we aren't paying a high price for them.
All scientists who've looked at it know we have to phase away from burning fossil fuels. That means we've got to put a lot of effort into alternate energy technologies, but we're still subsidizing fossil fuels and not subsidizing most of the alternatives. It's not going to be an easy transition.
There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.
As you know, the fossil record includes not only the ancestors of crocodiles and whales, but also the ancestors of human beings. And this, of course, is why evolution remains controversial.
It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.
What the fossil record does do is to force us to contemplate our place on the planet. We are but one species of several hominids that inhabited Planet Earth, and like our distant cousins who went extinct fairly recently, our time on Planet Earth is also finite.
Solar and wind are now cheaper in many places than some fossil fuels and within the next two years, three, four, five years at the most. What the exponential curve does isn't going to go away. It is totally over for fossil fuels and nuclear. Nuclear's actually gone out.
