The power grid problems islands have is a really interesting topic. Just the other day I read an interview discussing Taiwan's energy situation[0] and even though I am familiar with the various factions and the surface level debate, it prompted me to think a bit deeper on the unique challenges islands have as marginalized geographic entities. I didn't grow up on an island so I'm not sure if people who do are more conscious of the precarity, but you'd think if they did then they would place even more emphasis on getting energy independence. It's one of those things that would be cool to study if I could go back in time and choose a different specialization...

I live on an island and my first priority after getting a full time job again is to buy solar and storage good for a few days of my homes usage. The cost of energy is increasing here and I don’t see it ever going down since we’re still using oil for the most part. I plan to build a little wood workshop shed in my yard and cover it with solar panels and put some batteries in it. I should only need about 30 kWh of storage to cover three days use, and maybe 2 or 3 kW of panels for daily use and recharging the batteries; except for the EV, which I normally charge once a week but I can just start plugging in during the day instead. With that setup I can keep connected to the grid and eventually see if I can go off grid after a few years, or possibly add more solar and storage later if I find the first phase wasn’t enough.

However, that’s only possible because I have money and knowledge; most people don’t have that and so as a whole we’re kind of screwed here. Costs will continue to rise while not enough renewables are installed, usually on individual homes which only helps those individuals.

I have a friend in the Bahamas who had setup his entire home up for solar and even to reclaim water from the roof. The builders messed up the reclaim water system I forgot the reason but he mentioned he cannot drink the water whatsoever because of the screw up, so he has to eventually rework all of that, but in terms of power he is better off than most since he is setup for it with batteries and everything.

Some public schools in Puerto Rico started putting solar panels on their roofs after Maria which imho makes sense for all public schools all over the US / world. You have kids at school during the day, rarely during night. When schools not even open you could either put that extra power into the grid or store it for rainy seasons.

Alternatives include generating power from wind as well.
