I expect we will still have wind in 20 years and using infrastructure to turn wind into electricity seems obvious. The other real advantages to wind farms is you get energy sooner and it is simpler to scale exponentially. AKA 1billion wind farm = 50 mil profit and next year you have 1.05 billion wind farm which makes a 5.25 million profit so you now have a 1.125 billion wind farm next year... You can do similar things with debt financing, but that's higher risk.

Not to mention a smaller Not In My Back Yard problem. I consider oil mostly a done deal, we are going to burn most of the cheep oil because it's just so useful. But there is far more coal luckily it's far simpler to replace coal power plants than oil in cars / boats. We are also close to the tipping point where the free market is going to switch to wind on it's own, because it's cheaper.
