The G-7 or Group of 7 major industrialized nations at their summit this week pledged to reduce the carbon footprint in their economies, and further to completely remove all carbon by the year 2100 or 85 years from now. The G-7 includes Canada, the United States, European countries like Germany, France and the UK, and Asian powerhouse Japan. Eighty-five years sounds like a long time, but think for a moment what no carbon would mean to our society and our lifestyle expectations.
It means no carbon fuels such as gasoline, diesel or jet fuel allowed. Planes, trains and automobiles will no longer exist in our world unless they were powered by non-carbon fuels. That means no coal, no natural gas and no crude oil in any form. They’re all are carbon-based.
Hydrogen, nuclear, solar or wind power are the potential alternatives. Visualize cars and trucks adorned with sails moving on our highways much like the sailors of old. Perhaps solar panels will be much smaller and more efficient by then and drivers will have vehicles constructed of solar panels top to bottom. When the wind dies we’ll be stranded, becalmed like sailors of old, or if it’s cloudy or when night falls drivers will be unable to go further that day.
Electric cars are also an option but remember the power to charge them is generated now by fossil fuels (carbon). Proliferation of electric powered cars means more power to be generated.
Nuclear power is non-carbon but we’d have to develop compact nuclear reactors to power our vehicles. Would we really want millions of nuclear cores traveling down our highways and byways at high speed. Accidents might result in nuclear explosions or at best meltdowns and radioactive releases to the atmosphere on a routine basis. Massive amounts of nuclear waste would be generated as a byproduct.
Hydrogen is a non-carbon fuel. Best of all it can be sourced from water an abundant resource. Water is H2O, two parts hydrogen and one part oxygen. Separation is an expensive process today, but could become cheap if there was a demand. The biggest disadvantage to hydrogen is his extreme explosiveness. It is downright dangerous to handle.
Airplanes will be drastically smaller and slower powered by solar or wind power. Traveling around the world will take a vast amount of time. Tourism will become localized. Trips to faraway places will be a thing of the past.
Unless a viable non-carbon alternative fuel is discovered between now and 2100, society will be forced to live a slower pace and stick closer to home. The goods we enjoy today that come to us over long distances will no longer be available. As an example fresh fruit and vegetables in the winter will be a thing of the past.
Society will be markedly low-tech. Our high tech society will cease to exist. Carbon based chemicals are a necessary part of our computers and high tech toys and tools. Replacements don’t presently exist for those chemicals derived from carbon.
I’m not a scientist or an inventor, but I have a hard time imagining where the cheap, abundant alternative to carbon-based fuels and chemicals will come from. I’m not saying a complete phase out of carbon-based fuels and chemicals can’t be accomplished, but it’ll take a complete reinvention of our society and its expectations.
