Something which is very important to consider is the timeframe. When do you actually need the money? For how long can you leave it untouched?

Given your situation I'd put the vast majority of the money in a bank account or a really cheap money market fund, a certain fraction in blue chip corporate bonds, and an even smaller fraction in shares of stable conservative "boring" companies with a pretty predictable income stream. Like a shipping company with all its ships on multi-year fixed price contracts and the customers having a low counterpary risk, or a utility in a regulated environment, a mining company with fixed price deliveries, and so on.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
