Dienas grauds

A lot of people, including in the Government are absolutely unaware what it means, even if we lose electricity for only seven days.”

 

vara bungas: Kamēr US jau atvaira RU uzbrukumu, arī briti norūpējušies par elektroapgādes drošību.  Apdraudējums gan nav jauns, par to ir domāts un spriests jau labu laiku. Par šo problēmu   labs izziņas resurss ir Cambridge University’s Centre for the Study of Existential Risk, kas ne tikai biedē, bet arī piedāvā risinājumus  (spoileris – svarīgākais ir koordinācija valdības līmenī).

 “our power grids are becoming ever more crucial. Cities will be paralyzed without electricity, and the lights going out will be the least of the consequences… everything else that urban life depends on is vulnerable to breakdowns, errors, or even intentional sabotage of the system.”

      The list price for a new Tesla Powerwall 2.0 battery, which offers twice the storage capacity of the original Powerwall, is $5,500. Supporting hardware adds another $700 to the equipment costs, bringing the total to $6,200. Installation can add anywhere from $2,000 to $8,000 to the final bill.

      It is important to note that the list prices you see don’t include the cost of installing your Powerwall on your property. Tesla estimates that installation will add $800 to $2,000 to your bill. However, this estimate doesn’t include the cost of electrical upgrades, taxes, permit fees, or connection charges. EnergySage users have reported installation costs that add anywhere from $5,000 to $8,000 (before any financial incentives are applied). The final number will be dependent on the specifics of your installation.

      If you want to install the Powerwall as part of a solar-plus-storage system, battery costs are just one part of the equation. An average 5 kilowatt (kW) solar energy system costs anywhere from $8,500 to $16,000 depending on where you live and the type of equipment you choose. That may sound like a lot of money, but installing a solar-plus-storage system can be a worthwhile investment. Solar battery economics depend on a few different factors. Whether or not the Tesla battery pack makes sense for you depends on the way that your electric utility structures its rates, as well as your reasons for installing a solar battery.
