PV is one of the easiest renewable to install here so it's now heavily being installed now, but it's one of the most unstable energy source so can't be relied so much for a primary option. I'd like to see floating wind development but it seems that its development is now in progress. There's also typhoon and tsunami. I agree that buildings improvement is also important that is not much advanced.
