I would be working to build as many Solar, Wind, Tidal, and other renewable power plants as I could and building the high transmission power lines required, if any are, to bring that power to where it is needed.

I would work through the EU to encourage the countries along the southern Mediterranean to build Solar and Wind based power plants and the high transmission power lines needed to bring that power to the EU.  (Across the Gibraltar Strait?)  

With oil going bye-bye as an energy source the world is going to have to replace those terrawatts of energy with something.  That something is, most likely - given our current stage of technology, electricity.   The EU needs to be building these renewable plants as fast as they can in order to ease the transition from oil to electricity as well as to use oil (while it is 'cheap') as the energy source to build the plants.  

Along with that do or push for:

1.  Encourage or mandate (through pricing) conservation

2.  Encourage or mandate the power companies to purchase a goodly hunk (25%, more?) of their power from producers within a 60 kilometer radius of the customer.  This to encourage the development of local and regional power production.

3.  50% tax credit for the cost for businesses who establish their own Solar, Wind, or etc. power plants for their business.

4.  50% tax credit/refund for the cost of doing the same for residences.

5.  Institute the 'Energy Prize in Memory of Alfred Nobel' for the outstanding contribution in the area of energy conservation, production, distribution, storage and so on.  (Silly, but if one can be given for Economics, why not?)

6.  Institute an equivalent prize for an Engineer's outstanding contribution in & etc.

7.  Institute an EU-wide 'Energy Fair' for K-12 (in the US) pre-university students with tiers starting at a local area, then regional, national, and ending at the EU.  The top 5 winners at each level go one to the next level and at the EU level get a suitable reward.
