Electric Vehicles

Going green is our new mantra. This mantra espouses sustainability. While a clear definition of sustainability awaits, we do know that some things seem more sustainable than others. For example, electric vehicles get proclaimed as the new, sustainable transportation, i.e. they don’t emit green house gases. Let’s see if this satisfies our mantra.

Humans are enamored by vehicles. We have over 1.2billion in operation today. But transportation needs energy, about 1.1×1020Joules annually, much of which is for vehicles. Further, we should surpass 2billion vehicles by the year 2035 hence more energy is needed. As transportation is key to our GDP, then human prosperity may well depend upon continued infatuation.

Today, we produce 1×1020Joules of electricity. Fossil fuels generate about 63% of this. Fossil fuels are not sustainable. Currently, electric vehicles consume an insignificant amount of electricity. But, to meet our mantra, we need to remove fossil fuels from electrical production. And to meet future energy demand for vehicles, we need to at least double electricity production. This future for electricity isn’t sustainable.

From the above, can you see whether electric vehicles satisfy the mantra? Going green by replacing petrol burning cars with electric vehicles wouldn’t reduce energy consumption. It may sustain the GDP, at least temporarily. We ask, “Can we maintain personal transportation in our mantra and still go green?”

Fire! Controlling this wonderful, exothermic, chemical reaction enabled humans to vault over all lifeforms and become dominant on planet Earth. Some argue that our ancestors had control of fire over a million years ago. Not quite as long ago, we learned to use similar chemical reactions to access the energy stored in fossil fuels like petroleum. Very recently, we learned to split large atoms into smaller ones via controlled nuclear reactions. And we used the resulting energy release to further our domination on Earth.

With nuclear energy, we have controlled, ready access to very, very large amounts of energy. We’ve built large nuclear power reactors beside many population centres for this very reason. We also build floating reactors to bring accessible energy to demanding places. For almost ten years MH-1A supplied 10MWe to the Panama Canal Zone. Now, the floating Akademik Lomonosov ($232M), a brand new endeavour, will provide a similar service in that it can use nuclear fission to provide 70MWe to whichever port it is alongside. Currently it’s slated to replace the Bilibino nuclear reactor (164.8GW.h) nearby Pevek (65°N,170°E).

We recognize that our civilization needs energy to progress. Actually, we need very large amounts of readily accessible energy simply to sustain ourselves as the Akademik Lomonosov demonstrates. Over the last few decades, and centuries, we’ve become accustomed to consuming ever more readily accessible and cost efficient energy. But quantities of fossil fuels and of nuclear fuel are limited on Earth. What becomes of our civilization if the consumption trend continues but the energy supplies fail? Can we rely upon fire to maintain our civilization?
