By now, you realize that non-renewable energy sources will be fully consumed. Some suggest that it might occur within 50 years; some sooner; some later. But it will occur and it will occur relatively soon. And yes, their burning will add to the existing noxious pollutants. After, we will have no more fossil fuels and a dirty atmosphere.
What then? We will gather energy from renewable sources such as wind and solar. But, these sources currently amount to less than 20% of global energy consumption. And there’s little to no chance that they can provide all of our desired energy. We suggest that there will never again be a source of energy as utile and promiscuous as today’s fossil fuels.
Let’s look to the future and consider the usage of the finite amount of fossil fuels remaining. Do we continue apportioning energy consumption to maximize the human population? Do we drastically limit the amount used to avoid pollutants and re-learn to live simply? Or do we flame-out and use the remaining stores in one last hurrah? We could settle humans on the Earth’s moon. We could battle each other into extermination. We could build fusion reactors. What is the plan for civilization?
