Perhaps growing more olives is the answer.

Excerpts from:

The half-life of plutonium is 24,000 years.

The latest estimate on the cost of cleaning up the waste from the last 50 years is 56 billion pounds ($97 billion).

The sludge that flows down the heavily armored pipe into Sellafield's vitrification plant after plutonium and uranium have been taken from spent fuel rods for reuse is a hell's brew still emitting 40 times a lethal dose of radiation.

These are cooled, closed and scrubbed before being sealed in insulated steel flasks and taken away for storage where, standing 10 deep in a concrete core and capped by a three-meter (10-foot) plug, the heat from the radiation is still tangible.

Now here is something for the mathematicians here to calculate.
How much has the nuclear energy development and use actually cost throughout the world and how much will it cost to clean up all the waste material.

Now, if all that money would have been spent on growing olives, how much energy would we have received out of it?

Excerpt from:
Here

"There were no storage areas for charcoal. We have discovered that to melt copper you need five kilos of olive oil, compared to 80 kilos of charcoal.".

I think that using renewable resources such as vegetable oils in vehicle engines would be a good idea. Using solar, wind and other power sources to generate electricity and then to use the electricity to convert water into Hydrogen and Oxygen might also be a good idea. Right now there are hydro electric power generating stations that produce power that is not used during low demand times, why not use that power to generate Hydrogen and then use the energy from that gas for various purposes.

I think it would be more economical and safer in the long run than nuclear power.
