[permaculture] what about lubrication?

Before one accepts such hyperbole it is an easy matter to check out the
source and other sources.
Blumes book has considerable hyperbole, and the statement that "Brazil
imports no oil what-so-ever" is another example of that tendency.
Brazil's imports of crude oil in 2008 averages 169,000 barrels per day, and
petroleum is 225,000 barrels per day according to the Energy Information
Administration a U.S. government tracking office. While that is a
considerable reduction from the past it certainly isn't importing "no oil
what-so-ever". That's not to say that they don't use more oil than that but
the rest is from their off shore oil fields.
The cost to the ecology of Brazil is enormous as they slash and burn primary
rain forest to grow more ethanol. Brazil now is the worlds largest exporter
of ethanol putting even more pressure on their forests. Ethanol does not
seem to curb rapacious greed.
Nothing comes without cost and it is wistful thinking to presume that
ethanol is the magic bullet that lets us go our merry, two car family, way.
We are destroying the planet with our profligate use of oil products and we
will continue to do so with ethanol anyone who says otherwise is delusional.

There are a lot of synthetic oils on the market today, and, in fact,
if you love your engine, you should be using them rather than petro oils
as they are much superior, reducing friction and heat. That's not to say
they are made from all renewable sources, but it's a start.
Also, biodiesel works great for two-stroke lubrication -- the gas
mix in chainsaws, etc. Canola oil works great for the bar/chain lube in
chainsaws, except when it gets too cold.
