Re: Lithium battery costs have fallen by 98% in three decades
#2The article says that today a battery pack the size of a backpack and that weighs about 40kg, can power a house for a day. Is that really so? Would that be a normal house, being powered for an entire day? I find it hard to believe that battery would pack that much energy

A Tesla Powerwall 2 weighs 114.0 kg and provides 13.5 kWh.
Average US household electricity consumption is 877 kWh/month, which would be 29kWh/day.
Either they mean a very efficient/small house, or homeowners with unusually frugal habits.
Edit: Average UK household electricity consumption appears to be around 10kWh/day.

At best it would store about 8kWh, so... it would have to be a pretty efficient house.

I think that depends on how much heating/cooling is being used.it should be enough for just lights and devices.

40kg translates to 4-9kWh depending on the chemistry, meanwhile houses in the UK draw around 3kWh/day averaged over a year so unless a house is woefully inefficient, it checks out.

Very much depends on the home. Tesla Powerwall 2 seems to be 13.5 kWh at 114 kg. Energy consumption can be anything from 30 to 40[1]. So one Powerwall 2 unit probably won't get you through the day if you use that much.

Or houses not in the USA. http://shrinkthatfootprint.com/average-household-electricity...:
“The average American or Canadian household in 2010 used about twenty times more than the typical Nigerian household, and two to three times more than a typical European home”

Here in Burkina faso, I use between 5 and 12kwh per day with air con some months taking it close to 15kwh. If the price keeps coming down and with some solar installation, one can leave the grid in a couple of years time
