Despite the people, water, and electricity are another issues.

Taiwan is a small country with limited water resource due to the lack of land to have long river to keep the water on the ground.

For the electricity, nowadays, many BIG TECHs demand "green" electricity to manufacture their products, but once again Taiwan is not a big country. There is no enough area to hold the solar plates and the weather there is not suitable for wind power because of the typhoon.

These are the nature limitations. There are also other issues such as lack of engineers, the risk if expansion is not worth it in the future, etc.

IIRC a solar farm is being built in Australia which isn't going to touch Australia's own power grid, but rather is going to connect to Singapore's power grid using a pair of undersea HVDC cable runs.

Taiwan could probably get in on that action. If you're already running a 3500km cable, you could run a 4500km cable just as well.

(Kind of annoying that Taiwan can't just buy green energy from China — very easy logistically — but that's extremely politically untenable.)
