I wish it was as easy as deciding to switch from fossil fuels to non global warmth producing sources of energy. What’s involved is a major replacement of every mechanical contraption currently in use, the entire global life support system machinery. One example: How to manufacture enough clean running vehicles and get them to people and tow their old gas hog cars to — where?
How to close down the coal driven electricity generating plants and switch all electrical power over to solar, wind, geothermal sources without having to shut things down during the transition for purposes of rewiring,
Again, no matter how much we might want to, how deep and real our desire to have things be run clean and green, we are not in a position to enact this changeover by making individual choices. There isn’t enough time for social evolution to get us to that place. Not enough people even truly believe that a change of this magnitude is really necessary.
We can all do what we can in as many small ways as we can. But unless someone shows up who can lead humankind into changing how everything is done, the person I have called “Green Jesus,” causing a major transformative revival to sweep through the developed world, I have trouble envisioning how the needed changes can come about,
