PS
I first became seriously concerned about changes in our climate in 1981, the year I learned that I was going to be a father. I was concerned about what the future would hold for our child. Since then I have read what I could about the environment, energy production and use, promising new technologies and the ancient ways of the guardians. I realize that for a number of valid reasons there need to be, and there are, many different ways, big and small, that we can employ to win this "war".
Voluntarily or not, we must all start doing things that will reduce and stop the production of GHGs. I personally believe that government intervention can, and should, bring about the quickest, biggest changes as we do not have time to waste. In the meantime, I am spending a lot of time researching.
What Elon Musk is doing has had a profound impact and he is correct in looking to the sun as a great source of energy. But batteries will not solve all our problems.
I believe that hydrogen's role will be even bigger than we can currently imagine. The cost of water electrolysis and carbon-fuel pyrolysis is decreasing. In some instances it is already competitive but the knowledge must be shared in order that the technology is implemented.
The true cost of CO2 and other GHG pollution might not be entirely attached to the products and services that create them but we must be willing to pay that price. We will pay a far greater price if we do not. Call or write your elected representatives. Speak to the owners and managers of the enterprises with which you do business and ask them to provide "greener" alternatives. In a few years you and your children will be glad that you did.
