Kauai,Hawaii @ 55% reneable

[aerohead]

Last Tuesday,PBS Television's NHK Tokyo Television's news program did an encore presentation of a January,2020 report.
*The Hawaiian island of Kauai had attained 55% solar electricity production and night time delivery capacity via Tesla grid-scale battery storage.They were saving $millions by scaling back in diesel fuel requirements.By 2045 they expect to be at 100% solar and zero carbon at the grid.AES Corporation is company involved in the project.
*Kyocera (makers of photovoltaic panels) was offering a product akin the Tesla's Powerwall,allowing Japanese with rooftop PV to store and use solar electricity.
*Japan's Malibu Hotel became the world's first commercial building with the capability to run off BEVs plugged into its EV chargers in the hotel parking lot.The hotel was offering employees incentives to purchase BEVs for themselves.The BEVs shown were exclusively Nissan LEAF cars.In the aftermath of an earthquake/Tsunami event,the hotel would have a few days of available stand-alone power,should the grid go down.

Kauai is the perfect place to go solar. Their solar hours are fairly regularly distributed throughout the year as well as heating/cooling requirements, and grid electricity is among the most expensive in the country.

Doesn't make sense here in the PNW when electricity demand and daylight hours vary a lot by season.

Replacing fossil fuels on power generation is a good measure. I would only take it with a grain of salt if such move becomes an excuse to push a move toward EVs like it has been proposed in Fernando de Noronha, Brazil, even though most of the power supplies in Fernando de Noronha still resort to Diesel-fueled generators.

I'd rather trust Kyocera over Tesla.

Japan's Malibu Hotel became the world's first commercial building with the capability to run off BEVs plugged into its EV chargers in the hotel parking lot.The hotel was offering employees incentives to purchase BEVs for themselves.The BEVs shown were exclusively Nissan LEAF cars.In the aftermath of an earthquake/Tsunami event,the hotel would have a few days of available stand-alone power,should the grid go down.

My main concern about BEVs is the range-anxiety, but the unstability of the power supply under some environmental conditions is also quite bothersome. A plug-in hybrid OTOH could make sense not only as it addresses more effectively the range anxiety, but also as it may eventually provide backup electric power for the household. I like to consider this ability in a similar way to those old tiller-tractors with a "multipurpose" horizontal single-cylinder Diesel engine usually coupled to the transmission and implements with a set of pulleys and belts. Some even feature a 220-volt power outlet even when they're not coupled to a genset.

Well that's one place that makes sense to do so.
No natural resources besides tons of sun and clear weather and incredibly isolated. Beats running everything off fuel oil.

EVs are perfect for Kauai too. The island is 33 miles long, so there's hardly any reason to have range anxiety.

As I've been maintaining, islands are the perfect place for EVs. There's no way I'd own a gasser on any of the Hawaiian islands, especially considering the plentiful sunshine, moderate temperatures, and high fuel prices.

Yeah all your fuel has to be shipped like 2,000 miles.
Solar panels ship them once and they should last 25 years.

I'm disappointed that more headway hasn't been made on OTEC. Hawai'i had an operational pilot plant in 2015: en.wikipedia.org/wiki/Ocean_thermal_energy_conversion#Hawaii

I came here looking for a place to drop this: www.washingtonexaminer.com: Trump administration approves largest solar farm in US, expected to power 260,000 homes

The $1 billion Gemini project would be the eighth-largest solar facility in the world, the Interior Department said, generating 690-megawatts of power, enough electricity for 260,000 homes in the Las Vegas area and potential markets in Southern California.

Nevada utility NV Energy, a subsidiary of billionaire Warren Buffett’s Berkshire Hathaway, is providing financial backing to the project, which will be completed as early as 2022. It will generate more than $3 million annually in federal revenues, the Interior Department said.

I always see a concentrated solar plant flying into LAS. My understanding is those are much more cost effective than PV, so I wonder why that isn't being pursued?

I'd like to see pumped hydro tested on a large scale, like Lake Mead.

It's a matter of how often it would be either needed or easy to drive it to the mainland.

As long as sunshine is plentiful, then an EV with built-in solar panels might make sense. The distance to the mainland rendering the chances to ever take such vehicle out of the islands to zero could also be considered.

Hawaii has a single fuel refinery and they had 2 but it closed down many years ago..


the cheapest gas price is 2.25 THAT is way cheaper then california locally it's 2.89
