Then, PV make sense as an investment in five years, not now.
If wind is cheaper than new nuclear, we could ask ourself if the cost of
new nuclear is inflated by burdensome and not useful regulations and
taxes and if the wind cost compute all the costs or only what is
expedient to compute. If you want compare wind and nuclear, you must
compare them for all their feature. Do nuclear stop working when the
wind stop blowing? Do you added the costs of storing the energy output
of the wind farms? The costs of the gas plant needed to compensate the
wind farm when the wind don't blow?
And what about your favourite "climate change". What if, after we invest
in wind farms, the climate change and there is too much or not enough
wind for the wind farms?
GE is typically clueless, so that doesn't necessarily mean much.
In five years a sizeable part of the world economy could be powered by
LENR or some hot fusion device. Or oil and coal.

In between keep your money (gold) safe.

In fact, governments all over the world are better. The current deficits
and debts are proof of their ability to plan long term. The current and
recent wars show they are good at planning long term. The USSR was,
probably, the best able to plan long term.

In fact, I could say the governments of Germany anticipated peak fossil
moving from nuclear to coal. Or it will buy electricity from its nuclear
neighbours at higher costs. Or both.

Then? Are these government planning for the long term or are they
auctioning their services to interests groups.
One or the other, you can not have it both ways.
