Of course, nothing fails like a battery. The EV push will fail too without trillions in electrical infrastructure. I know this for a fact and so does the electrical industry. Ohm’s Law proves this too but who’s ever heard of that? Lol.
The biggest problem with living on an island, in the middle of the ocean, is that they can't run an extension cord out to you, when your electrical grid comes up short. Saw it 30 years ago, when I lived on Guam. Rolling blackouts SUCK.
Depends if electric vehicles are allowed to be naturally be adopted and fizzle out when sales fizzle out at around 10%. Or is the government going to try and force sales to be 50% or more.
Guess we got that answer this week, as JoBama has decreed that the majority of new vehicles sold will be EV's, by 2030. Never mind what they government plans on doing, if people refuse to buy them, driving the automobile manufacturers to bankruptcy, because they've got lots full of EV's that they can't sell. I look at what they were able to do in Cuba, after Castro took over, and they could no longer get good Detroit-built autos. Granted, the technology was MUCH simpler, but they have cars still on the road, from the 50's. Heck, I still see plenty of Pontiacs, Saturns, Oldsmobiles & Hummers on the road, and they stopped making them 15 years ago! Imagine what the aftermarket demand will be, on replacement parts to keep non-EV's on the road.
Another EV manufacturer went into bankruptcy protection this week. Fisker. Their business model always appeared to rely on government forcing people to buy electric cars or baiting them with lavish tax credits. Even Tesla is expecting slower growth in EVs over the next few years. There is no way "most vehicles sold" will be EVs, it likely won't even be 20%. Other negative ev growth news last year GM and Honda ended their partnership to "get Tesla". Ford expects to sell fewer lightenings and EV mustangs in 2024. VW put their billion dollar battery and EV plant expansions on hold. BMW canceled plans to buy some old vehicle factory expand it and turn it into an EV and battery factory. Merc did something similar to VW.
Maybe the solution is to make internal combustion engine-powered vehicles, then tell JoBama that they "identify as EV's"??
Wave is expensive, unreliable, fragile and prone to damage in rough seas plus it always has salt water eating away at it. Anything that harnesses wave power needs to be able to be dragged up out of the water on to the beach when a hurricane is coming. They use geo thermal on the big island.
Hydro should help some of the year. There's plenty of elevation drop and the place looks rainy. No hoover dam sized stuff, bunches of tiny ones.
There are plenty of ways to do wave action generation, it's a matter of proving or disproving them in that environment. The objection is more likely because of the compromise to the ocean view and surfing sport. Work the mills on the le side of the island, and when the supply exceeds the demand pump water from lower reservoirs to upper reservoirs to be used for hydro generation or recharging the ground water.
A lot of hopium concepts shared on this thread, all the whizzbang technology used in small isolated locations, which is super expensive and totally reliant on fossil fuels to manufacture. In Britain they are building new housing estates with "Geo-thermal" heating, which is basically a big hole drilled in the ground filled with water that's piped around the estate and used in electrically driven heat pumps. Generally speaking Heat pumps are just a new name for air conditioners but some use other methods. Reverse cycle conditioners don't work in sub zero temps because the air outside is colder that the evaporator temp. These systems are very expensive and not all that efficient so a traditional heating system, Gas say, must be installed alongside as well. That grid in Hawaii is the same principle, super expensive renewable technologies that obviously require a conventional fossil fuel backup. Now fast forward a decade when the debt finally catches up and these systems can no longer be afforded. By then the panels will be seriously degraded, the batteries rooted and the wind turbines in need of replacing. Renewable rebuildable systems were never going to be the answer.
IMO individual homes should be built implementing their own solar and wind options. It is a sad state of affairs that (thermal) solar energy is older than electricity and it is still not being used as common as it should. I had books that were published back in the early 60 that showed several homes successfully operating on thermal solar, both in heating and cooling. and not geothermal. Photovoltaic solar goes back to the late 1800s early 1900s. and battery power goes back to the time of Egypt. Excuses don't fly. Lazy and cheap, that's the problem. Build the home implementing this ancient hi-tech and make people learn to be responsible do their own production of power and they will become more conservative on their own. I was poor and bought used equipment to get started. instead of going on vacations I built up my solar and saved a fortune in power. As a result my kids both learned to be conservative and build their own solar reserves. Heating and cooking with wood is legitimate. my daughter learned to cook and bake in my wood cook stove, and she now is a head baker in a store in Idaho. My son is a licensed construction contractor in Pennsylvania most of his work is rebuilding million-dollar homes.
One of the big geothermal plants on HI was nearly decoyed in the last series of magma flows. Hawaii power plant shut down as lava nears geothermal wells | Hawaii | The Guardian The other got smoked Former Hawaii Geothermal site destroyed by lava - Hawai‘i Groundwater & Geothermal Resources Center down up not out 5 years after lava nearly destroyed it, Puna Geothermal announces expansion plans (hawaiinewsnow.com) except the local greenies hate it. It 'smells bad' tho it could provide 100% of locally needed power. *Ormat* as a search string will explain the tech behind the power plant
