Solar Panel Home Battery Pack

Wouldn’t it be weird if one day in the futureyou were buying a home and the listing said, “batteries not included?â€� Yeah well, thatcould totally happen. Hey there people, Julian here for DNews. Electricityis pretty great. It powers my toaster, my fridge, my hairdryer, my clothes dryer, myair conditioner, my humidifier, my dehumidifier, and my pc I use to watch science tutorials.I think I’m gonna keep using it. The problem is, everyone in all the other houses feelsthe same way, usually at about the same times of day, and they’re driving the cost ofthose tasty kilowatts up in the evening. Of course during the day if you don’t wantto use power from the grid, you could get

some solar panels and harvest sunlight, butthat’s not helpful when the sun’s down, also known as nighttime, also known as thetime I need to have electricity to turn lights on to not bang my shins on all the furniture. Enter the battery powered home. The idea isa rechargeable battery stores energy from solar panels during the day or from offpeakhours when grid energy is cheapest, and uses that energy during the rest of the day. Theproblem is if you’ve ever bought batteries you know they cost approximately one arm andorone leg. Elon Musk thought that was a silly hangup for what is otherwise a great ideaand decided to do something about it.

Elon Musk, for y’all that don’t know,is basically what would happen if Tony Stark lost the goatee. His interests range fromonline money movement to commercial space flight to, most importantly for this topic,electric cars. His company Tesla Motors has been refining electric car batteries for years,engineering them to be lighter, longer lasting, and more efficient. Why don’t we take allthose batteries, and put them on a wall? So they did that. The Tesla Power wall Isbasically a bunch of lithium ion cells in a sleek case. They’re compartmentalizedand liquid cooled to solve the knotty problem of overheating and burning your house down,something that is generally undesirable. If

you wanted it as your main power supply there’sa model that can store and discharge up to 7 kWh daily and costs $3000. Best of all itshould last 10 years, which is approximately 8 years longer than my laptop battery madeit before it wouldn’t hold a charge anymore. The trick to this longevity is how much powerit outputs. It’s only pumping out 2 kW continuously and peak output is 3.3 kW. The problem thatthen arises is some appliances will use more than that output. An electric clothes dryercould draw that much power on its own. So if you want dry clothes, I hope you weren’tplanning on using a microwave too. If you wanted to be not reliant on the gridat all, you’d probably need a few powerwalls

to go with your solar roof panels. Dependingon where you live, your power consumption can vary widely, but the average US home in2011 used 940 kWh per month. A solar setup of that size would cost over $11,000, notincluding installation or taking tax credits into account. Then you’d need 5 Powerwallsto store all of that sunshine juice, so that’s another 15 grand. It’s an expensive prospectright now, but as the cost of batteries and solar panels continue to drop, individualhomes that are independently powered could become a great way to kick our fossil fuelhabit. Inexpensive home batteries are looking like a promising innovation.

They’re not the only company innovating.Intel creates the breakthrough technologies that make amazing experiences possible.Having Intel inside makes for better experiences outside.Intel drives innovation with products like processors, wearables and IOT devices, andwithin data centers. In the PC and beyond. Going green sounds like a lot of effort. Isit really worth it? Trace explains why yes, totally, it is, right here. Would you use the powerwall? Would it be asupplement for your energy use or would you go all out and be energy independent? Letus know in the comments, subscribe, and I’ll

Elon Musk Debuts the Tesla Powerwall

welcome everyone to, basically, the announcement of Tesla Energy so what I’m gonna talk about tonight is about a fundamental transformation of how the world works about how energy is delivered across the earth this is how it is today, it’s pretty bad it sucks! exactly! I just wanna be clear because sometimes some people are, like, confused about it this is real this is actually how most power of the world is generated, with fossil fuels

and if you look at the curve, that’s a famous curve, the Keeling curve which shows the growth in CO2 concentration in the atmosphere and every year it ratchets up, it gets higher and higher and if we do nothing, that’s where it’s headed to levels that we don’t even see in the fossil record well, I think we collectively should do something about this and not try to win the Darwin Award for us and a lot of other creatures too

the way the grid works today is this, you got coal, you got natural gas, nuclear, hydro and wind and solar but not enough wind and solar, obviously so that’s sort of the grid, typically, in most countries and then you’ll notice something which is that there’s quite a big difference in peak to trough usage so the peak usage is typically at least twice the trough usage so please bear that in mind, I’m gonna reference that again later in the presentation that’s an important point

so what we’re here to talk about is the solution I actually think it’s really a fairly obvious solution but it’s something that we need to do and the solution is in two parts part 1: the sun we have this handy fusion reactor in the sky called the sun you don’t have to do anything, it just works shows up every day and produces ridiculous amounts of power

now a lot of people aren’t clear on how much surface area is needed to generate enough power to completely get the United States off of fossil fuels most people have no idea, they think that it must be some huge amount of area like, maybe you need these satellites in space, and like sort of space solar power if anyone should be in favor of space solar power it should be me but this is completely unnecessary because actually very little land is needed to get rid of all fossil fuel electricity generation in the United States that blue square there is the land area that’s needed to transition the United States

to a zero carbon electricity situation it’s really not much and most of that area is gonna be in rooftops so you won’t need to disturb land, you won’t need to find new areas it’s mostly just gonna be on the roofs of existing homes and buildings so I really think that image is an important one to bear in mind when people are thinking about solar power like, how much will it take? is it gonna take some enormous amount? no, it’s just that blue square
