David,
I understand what you feel like. Look into Solar/Wind energy for your home. If may need to reduce your energy use but you can keep a reasonable amount of it. Than e-cars, some gardening ((maybe even community farming)).
The main point on this site ((in my feeble opinion)) is to stop being dependent on Industrialized society and become more community based. That does not mean that we lose everything, but our lives will change. The longer we wait to make changes the more catastrophic the changes will become for you and your local community.
My advise ((and take it for what it is worth, free)), think of taking different services out off your life and think of the changes that it would make in your life. Can you live with those changes? Is it possible to live a life you want to without the service? Do you need to change your expectations?
Than you may want to think of; What are the possibilities you would lose the service? Would you lose the service for only a short period of time, will it just be lost or would it be intermittent? Maybe your thought is we have a bank holiday and you need to only get through that bump.
After that you may wan to think of; What can you do to overcome those changes and live a life you want to live? Maybe as simple as adding a few solar panels to afford electricity and continuing to add them to reduce stress on the electric grid around you and you get the savings for it ((and true win-win)).
Most importantly, I advise once you decide the scenario you think is most-likely going to happen, make a plan and follow through. Nothing worse than having knowledge and not acting on it. Maybe your plan is too much or too little but if you have the ball rolling you can make changes more easily.
Best of luck!!
NOTE: In services I mean, either losing or not being able to afford utilities, gasoline, shopping, food, water, etc.

One of the most haunting comments in the Crash Course to me was the suggestion that our specialized society might be the result solely of the energy surplus from oil. This rings frighteningly true to me. I had been thinking it was the surplus of food. But now I see that it is not food, but energy. Energy allows us to create all the surplus food, and A WHOLE LOT more.
So, the question is this: if we really took this seriously and applied the full resources of the country, like we did getting to the moon, what are the chances of developing a rich alternative energy source? Is it in the realm of possibilities, or wishful thinking? It doesn't sound like solar or wind or even nuclear will get the job done.
I know this only solves one of the Es, but I like a specialized society. I don't really want to become a farmer and wood chopper. I like all the books and opinions and music and variety of food and entertainment that comes from surplus energy. I love surplus energy. I don't want to go back to the old days.
