Maintaining the grid and keeping enough power on it is a heavy expense
But so is filling and shipping tens of millions of batteries
Micro-generation also has a heavy cost because of the increased # of generators


The solution would have to lie in personal generation units
and possibly a voluntary gridding of the personal gens to create a power commune


Last I checked the U.S. "avg." was something like 11-13c/kWhr
With some states paying as little as 4 cents and others as high as 45c
If your Tesla uses a 5kW battery it costs 50c/hr to drive it.
Which amounts to about $10/day


You have a 600W television, and a gaming system running nonstop
A fridgerator, microwave, a/c unit...... well now the house costs 12$/day to run
Your monthly electric cost might be $700
Which is comparable to your rent in some places.


We can talk about "how cheap" it is,
But in reality, energy costs govern our lives.
We rarely go anywhere or move any product without paying an energy cost.
And there's a tax on every BTU

smokey2, where you get "5 KW battery" and who is driving 20 times this value (5 KWh x. 0,1 USD)  per day. ?Taxi-driver,okay !
Normal people needs 2 and more hours for consuming 100  KWh(10 USD/0,5 USD x 5 KWh) as "drive time" ( without rush-hour still-stand) with this electric/chemical  capacity by legal streets velocity !

Taking the "old-tech" GM Impala with 12 KWh/100 Km average battery capacity consume ( without regeneration)
this are by US-legal max high-way velocity 90 Km-h  10 hours drive time  per day !

When Tesla Motors is not able to deliver the electric car industry standard about max.  9 KWh (12 KWh - 3 KWh brake energy regeneration) consume then they have nothing technological special. !

https://www.google.com/search?q=tesla+car+battery-set&ie=utf-8&oe=utf-8&client=firefox-b-m
The Tesla Motors Model S is equipped with 85 KWh battery capacity. !
Do you mean a private household battery-set, delivered f. e.  by this company. ?

Good morning lancaIV, thanks for the informative reply.

Future technical standart of energetic consume by given existent technology :

112 sqm house as cube 1750 Wp and as dome 1200 Wp caloric heat aequivalent in the U.S. by average winter climate condition
by C.O.P. 10 heat  appliances a. heat pump  b. friction heater.  c. IR-heater 175 Wp and 120 Wp electric

Optimized oeko-energie appliances decrease daily "intelligent household" given 3 KWh consume to 1,5 KWh,with better electric motor,energy saving heat elements and special coatings.
Hot water we get  by new building constructions demanded solar collectors today or air-water-heat pumps or friction heater !
The accumulated private household electricity consume for 4 habitants/112 sqm in future:  < 1000  KWh electric

1400 KWh solar energy and 15% efficiency solar electric converter per year 210 KWh gain, with mirrors up to 266 KWh. 

So 4-5 sqm panel area for the average consume sufficient
By 60% efficiency photovoltaic converter and 1400 KWh solar radiation/sqm 1,5 sqm panel area sufficient.

Because sun energy is periodic,day/night,summer/winter, there will be supplementing  alternatives :


wind,water,active solar/photovoltaic,magnet batteries/amplifier

In summer for cooling we have the surplus " summer heat" energy for electric cooling  beginning with ventilation

Calculating with 5 EURO-cents/KWh on-demand SELF-generating system this means 50 EUROs per year heat+ hot water+ kitchen/bath electric appliances energetic costs. .

50/12 months/4 habitants per household :  1,05 EUROs per capita/month   electricity costs

                                                EXPENSIVE or CHEAP

1,05/30,5 days :                     3,5 EURO-cents per day/capita

                                                 3,5/130 EURO-cents per day

                                                                     AFFORDABLE

For well organized G-20 house-holds and well earning  3,5/1000.  EURO-cents per day/capita
                                                                                                                    (~ 1220 EUROs per month household income)

                                             energy costs are ridicolous as "concerning theme". !


Well organized house-holds knows that the change began 1972 :  THE LIMIT OF GROWTH

1972 related some years before somebody offered "future living style" :   

  https://en.m.wikipedia.org/wiki/Habitat_67
And 1972,the Olympic Village in Munich as "future concept": the"over-ground"  car-free village ( only underground)
   
            https://en.m.wikipedia.org/wiki/Olympic_Village,_Munich

This eco-political "car-free" movement had 1973 the "peak":
https://www.google.com/search?q=1973+autofreie+autobahnen&ie=utf-8&oe=utf-8&client=firefox-b-m
           car-free Sundays and car-free high-ways

        MORE CARE,LESS CAR

Americans aren't efficient at all.
Most of our citizens don't even care that Sheetrock comes infected with
Toxic Black Mold....


We DEFINITELY don't care that its' not thermally efficient.
We just put cloth in our walls to try and help.
Our average homes are so inefficient that the thermostat kicks on
3-5 timer per hour.
The pull from the start-up of the compressor and blower system
wastes more energy that it 'should' take to bring the temp of the house
back up to the users desired setting....
We THEN pay for the energy to do that until the thermostat shuts off again.


We know how to build a habitat that is so thermally efficient we don't even need an a/c system
But we don't, because it's too much work or not industry ready or whatever excuse we use to keep
doing the same crap.....
We need a leader with some degree of oversight to see the bigger picture
Not just the dollars in their pocket

We have in science knowledge neither a. G. U. T.  nor a G.U.P. !
And what helps us to know about low-/no energy need devices for our daily needs if we can not financial afford these. ?!
Sometimes academical advices are also far from reality :
http://www.rexresearch.com/cuinanoagwire/cuinanoag.html" ........eliminate need for indoor heating."
Only 12 W for body ambient conditioning,a success related to Daimler-Benz 90' R&D e-wear  invention with 80 Welectric consume  ! But I decide mainly for outdoor use. !

Argumentation : living at the sea-side,coast/beach 500 meters away the inhouse humidity/condensation needs to be diminished and this is with "12 W" body AC not possible,illness and textiles/mobiliar damage risk. !
Heat comparison : hot water electric 1500 W kettle and 1 liter water heated in 5 minutes and this hot water in an hot water gum bottle as body/bed warmer ~ 125 Wh hot water/4-5 hours "warming effect"~ 25 W/h

Condensation temperature : % humidity dependent 10-15 °Celsius inhouse caloric  temperature. !
Condensation and as effect/consequence mold is today one of the greatest problems in modern " pseudo-evacuated" modern construction buildings.( blower door teste !)

For old houses I would recommend these electric candle heater with dehumifier effect concept :
https://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=0&ND=3&adjacent=true&locale=en_EP&FT=D&date=19881019&CC=GB&NR=2203529A&KC=A#
The british inventor wrote about 2 x 200 W devices for (his ?) semi-detached house and 0°C to 14,5°C ambient temperature condition for beside heating also dehumidifying.as solution  !

[14,5°C was/is in much private households in winter/cold weather time average reality world-wide. !
German CIVIL COURTS DECISION: too less, minimum 20°Celsius in average in-house caloric temperature
Who buys with credit his home is by law not home owner;  legal term definition : Owner/Eigentuemer( credit-free) and credit-holder/User/Besitzer ;

can the credit giver= by law home owner - demand the home user to heat up to these minimum 20°C average temperature  ? YES ,HE CAN !  Credit object damage risc and worth lost risc ! ]

And 25W for the "small bedroom"

Undefined : sqm/sqft living area

Because several billions Earth habitants are living in deep-max 0°C climate areas this can be helpfull. !

As possible improvement  the heat bulb heater/dehumidifyer seriell connection.  :
https://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=0&ND=3&adjacent=true&locale=en_EP&FT=D&date=20041118&CC=WO&NR=2004100349A1&KC=A1#

2x200 W and 14,5°C are in personal absence ( work-time/holiday cabin et cet.) "physiological-physical ( but not legal if not home owner) sufficient,
for higher room temperature 3x/4x/? 200 W ( up to 2000 W units as by the inventor descripted) for average 16°/18°/20°also configureable. !

Attention : not linear calculation possible, condensation ( % humidity) enthalpy gains relationship !

Light/heat bulbs by same given nominal Wattage works with different radiation effect !
Also here since the 80' some technical improvements. !
Also with coatings on the lamp holder surface the results are improveable  !

Science = knowledge each one is in his life his scientist

Such an offer probably in the next years industrial and later commercial available. :
https://patentauction.com/patent.php?nb=11462
Actually ,by technical similar concept prototype,I estimate the 1 KW AC-amplifyer costs with 250 EUROs in seriell/mass production ( without over-head costs) for many people a technical solution for their ecologic energy use,but by their purse content : financial not affordable the buy, only possible as " device rent/lease"

   4x 200W e-candle heater/dehumidifyer and the amplifyer effect for such a semi-detached house
                        ~ 80 W-net electric input for warm and relative dry inhouse

                Which was the Daimler-Benz body ac e-wear Wattage in the 90'. ?

        Each one has to find his own right solution  !

Perfect ,by german academical theory, constructed 10 W/sqm "PASSIVHOUSE"-buildings have in real use 20 W/sqm consume ( Fraunhofer Institute study ), G.U.T./G.U.P. : + 100% 


The cheapest solution which me is known of electricity delivery= hydro-electric device , by costs calculation from material and industrial transformation to ready to use product and later physical and financial R.O.I.,is :
https://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=5&ND=3&adjacent=true&locale=en_EP&FT=D&date=19280203&CC=FR&NR=633752A&KC=A#
= multi-waterbattery-set
           
                         Future 112 sqm private4 habitants household energy consume
1000 KWh electricity per year ~ 2,74 KWh per day means

                                  274 Wh per day magnet amplifyer input need per day
1 MEREDIEU WATERBATTERY  electricity delivery  per day 12V x 1,5 Ah x 24 h = 432 Wh
                                                         But: per battery only  18 Wp per hour

1000 Wp consume after magnet amplyfier 100 Wp x AC-AC magnet amplyfier Wattinrushpeak :

          55 MEREDIEU WATERBATTERIES a 18 Wp DC~ 1000 W. to DC-AC inverter ( inverter Wattinrushpeak  ?)         
         to AC-AC magnet amplifier

                               Or WATERBATTERY loads conventional battery(  with the higher - accumulated- Wp)

After each 30 hours full battery load  : water as fuel re-fill

or more WATERBATTERIES f.e. 7 days= 7 WATERBATTERIESand 1 time per week refill

          Now :

DC or AC ( inverter) micro-grid and the Wattpeak and Wattinrushpeak knowing  if all needed electric devices in parallel or seriell-micro grid conection are in action/function  !
