I work since 15yrs for a 100K employee Energy/Utility company that has assets and sales entities on all continents. More specifically I work in a branch of Trading and Origination (Sales on steroids), currently responsible for the sales of all energy to Giants (energy intensive customers) and Stadtwerke (local utilities) in Germany. Something like a head of energy sales for Germany, for Gas, Power, Wind/Solar PPA, Biomethane, Biomass, Certificates, Market Access, flex products, structured trading products, LNG, etc. etc.
So also in response to
@Foxi 's comment, as I need to be in a trading room, which usually only exist in capitals, my room for moving around is already a bit more limited. Especially as many other countries in Europe would mean a strong paycheck cut. Basically in Europe, I could go to: Brussels, Paris, London, Frankfurt (or general Ruhr area), Switzerland and that is about it. I can't do my job from any place (I can do Work@Home, but try to limit this as much as possible, so as not to impact negatively my career).
We have a big trading platform in Houston, Texas, but since my specialty is Origination/Sales, those are usually positions better suited for locally connected people.
So either:
- I first move vertically in my current organisation, allowing me to move other places in the world, whereby less my local connections/market knowledge, but rather my leadership skills, will be important.
Recently applied for a country leadership position for Poland, but was refused as they were looking for someone with more managerial experience to handle support functions, while my main strong point is driving the business. My young age also did not help 
- I leave my company, only one viable choice in EU would be to Switzerland in order to keep valorizing my expertise on European energy supply, and keep the paycheck high enough (after tax). Although I'm open to other localities, if the pay is sufficient (that hunting passion is not paying for itself!)
I'm also trying to get a secondary stream of income going. Together with a partner in SA, we set up an import/export business of mainly taxidermy, into Europe. About a container a year for now, so we are barely making a profit.
