I'd second investing in renewable energy - if you're worried about what your investment money is being used for at least you'd know it's being put to good use.

Another thing to consider, depending on how much you have to invest, is solar panels. I have quite a few farming customers setting up large panels on their sheds - they're essentially creating a solar farm. They don't use any of the power it creates, as it's separate from their house etc. So all power gets 'sold' back to the grid. It takes a bit longer to earn a profit because the outlay is higher, but in a couple of years they're looking quite good.
