Toolbox for a future - 1 - Electricity and transport

As I stated before I'm not a strong believer in the unknown God. The future is going to be made up of things we know now, known tools, known solutions and known limits. It's going to be a real cold turkey getting out of the carbon addiction to paraphrase late president Bush. But the important thing to remember is that there IS solutions, there is a way.
The way may not the smooth and easy way we want it to be - but there IS a way.

What is the toolbox of the future?
  • Electricity and electric transport.
  • Permaculture
  • Electronics (Open hardware and DIY)
  • Open communication technology
  • Community
These tool can be made sustainable - that mean they can earn back there investment. As a plus these tools are also good for the environment.
Each of the points are major undertaking. And we are to undertake these big, costly projects when resources becomes less available.
Lets take them from the top.

Why electricity?
I have read A LOT about alternatives to oil. Hydrogen, palm-oil, ethanol (1st and second generation technology) and biogas to name some. One of the true wonders of oil is that it is highly compact and storable - meaning it can be put in a car. It sits there for 6 month until you decide to drive 500 km - that i truly amazing. And furthermore oil has the highest energy density next to uranium. Then we just have to make some more oil now don't we.. and sure sure we can "make" oil - the easiest way is to let plants do it (killing whales is another great way since whales are mostly fat) there is just a little catch there. Making food takes up farmland where we other-ways could grow food and modern agriculture has become VERY oil-consuming (1 cal food uses ~ 10 cal oil to produce). Neither does it produce very much oil for the work - In fact if you are to produce oil in the most part of world the you would need more oil for machinery and tools and pesticide and fertilizer than oil produced - the same goes for ethanol except some contryies like Brazil that have LOTS of sun and water and cheap labor, then you can make it work (ERoEI > 1). USA is in fact starving the 3. world by subsidizing Ethanol production with ERoEI less than 1 (and that just plain stupid and horrendous).
Hydrogen isnt better - the only reasonable way to make (in terms of ERoEI) is to convert oil to hydrogen..
Palmoil isn't a silver bullet either...
Biogas has also some problems in terms of scalability that does it very hard to see as an alternative to oil - but small scale biogas is here to stay - as it has been around for 2000 years. But from idea to powering all cars in eg. the UK or Sweden there is a long way to go. And to produce the amount of biogas needed to power all road transportation is doubtful, but trucks and buses seems feasible... but what about me and my car? What is that gonna run on?? Electricity!
The only real alternative to oil in terms of transportation is electricity. The only ones that have a problem of seeing that is the special interest groups. When you get down to the numbers - the electric car is realy a thing of the future.

To sum it up.
Cars - electricity
Trains - electricity
Trucks - biogas
Ships - ships has been sailing before - they can do it again.
Planes - no. There is no real future for transport by air unless some enormous scientific breakthrough.
Then there is all the wonderful thing you can do if you have electricity, like living in 21. century. The electric grid is one of the great wonder of our time that will live on in the post carbon world, the product of a true genius who all to few knows about - Nikola Tesla.
With the grid (we already have) we can power our (electric) cars. We can power machines and electronics. Electricity is THE game-changer making a modern future possible. Its either that or back to 1850 (after some adjustments).

More about permaculture next.
