New Tesla Battery Could Be A Game Changer For Marijuana Growers

Anyone who has ever grown marijuana indoors knows that it takes a lot of energy. I once had a garden that involved a dozen 1,000 watt lights, in addition to the fans and pumps and other things that go with it, and my electricity bill was consistently between $700-800 a month. I have friends that have industrial indoor gardens, and their bills are so high that they don’t even feel comfortable sharing with me how much they are. With more and more people opening gardens everyday across states that allow them, power is going to be a big issue for the marijuana industry.

One quote I heard is that indoor marijuana gardens use about 1% of America’s electricity. 1% may not sound like much, but when you really wrap your head around that number, it’s significant. And the industry is far from as large as it’s going to be. The ever-growing appetite for energy from the marijuana industry is something that worries public utilities. That’s why the new Tesla battery could be important to the marijuana industry in the near future.

For those that are not familiar with the Tesla battery, below is a brief description via GizModo.Com:

Unveiled last night, the Tesla Battery gives home owners and businesses an easy, slick, affordable way to store electricity at home. The 10kWh battery costs just $3,500 and can be “stacked” in sets of up to nine units. Larger capacity batteries of infinitely-scaleable capacity will be available to large businesses and governments. There’s three general use cases for the battery: storing electricity purchased during cheaper, off-peak hours for use during high-demand periods; storing electricity generated by solar power or other renewable sources for use around the clock; and as a backup power source for when the grid goes down.

I was a Public Policy major in college, and I have always been interested in renewable energy. My favorite form of renewable energy is wave energy, which is only in its infancy, but I find it absolutely fascinating. I interned at a power company my junior and senior year of college, and got to work around a lot of talented people that were experts in the field of renewable energy. They explained to me that without give innovations in the area of energy storage, renewable energy would never reach its full potential.

When a solar panel is converting light into energy, or a windmill, or some other form of renewable energy is being generated, it either needs to be used as its being generated, or it needs to be stored. Otherwise its lost forever. That windmill can be spinning like crazy, and generating a lot of electricity, but without a way to store it or use it immediately, it might as well just be an over-sized lawn ornament. That’s a big reason why the new Tesla battery could prove to be a game changer, for the marijuana industry and beyond.

The battery still has a long ways to go before it becomes a standard in the marijuana industry. The battery may be great for running a TV, but it’s a different story when an industrial marijuana garden is involved. But with that being said, the people at Tesla are wicked smart, and once they see the market potential in the marijuana industry, and the amount of good that can be achieved by reducing the carbon footprint of the marijuana industry, I think they will rise to the challenge.

  1. LMAO! Are you serious ” I’d wager, were we to open one of the Tesla battery units, we would find twenty smaller 6v AGM “golf cart” batteries wired up in series” The Tesla Powerwall is lithium and weighs about 250 lbs. 6 golf cart batteries weigh about 6oo lbs. The total size of the powerwall is 24kw limited to 7kw or 10kw. The 7Kw and 10Kw batteries are exactly the same. It also operates at 48 volts. That means you need 4 1.2kw (100Ah) sized batteries in series to get to 48 volts at a cost of about $800. 100Ah x 48 volts= 4800 watts or 4.8kw which nets 2.4Kwh of useable energy. Time will tell if the Powerwall works as advertised.

  2. While storage of energy is a great idea I have a different approach that still needs to be proven. It works on a small scale from already available products. Just a matter of if the state will allow it. If anyone is interested contact me through this blog first.

    Once again I will note that the difference is on how much energy consumption is needed. one deep cycle battery will indeed fit on a shelf. But a power bank of 90 deep cycle batteries will not.I worked in a factory that each power outage cost them over $150,000 and if they could find a battery or generator that could keep them going, even if it cost a million dollars, it would pay for itself in a years time. And when the tesla batteries are considerably smaller in size then a regular deep cycle I don’t believe they achieved that by using multiple batteries inside. There is a awesome documentary on the electric car, I believe you can find it on Youtube it is called “Who killed the electric car” which I believe explains why Tesla cars are so groundbreaking when cars like them really should have came decades earlier.

  4. Space-wise, those 1.2kwH batteries I looked at aren’t enormous (about twice the physical size of a standard car battery). You could easily put them on a shelf in the corner of the garage or in a cabinet in the basement that wouldn’t take up very much space. And I doubt the Tesla engineers would abandon the advantage of modular battery banks: in a battery bank, if one of your 20 batteries fails, you only have to replace the one failed battery, but if anything goes wrong with one BIG battery, you have to replace the whole thing. I’d wager, were we to open one of the Tesla battery units, we would find twenty smaller 6v AGM “golf cart” batteries wired up in series.

    Having given these Tesla batteries a couple days of consideration, I realized Tesla is trying to do for commercial/residential renewable energy what the company did for the electric car: marketing them for mainstream use by piquing public interest. Electric cars could have supplanted gas-driven vehicles 20 years ago (the technology existed), but the push-back from the oil and auto industry was enough to quash production. It wasn’t until Tesla made electric cars sexy that the market began to resurface. If Tesla can do for renewable energy what they’ve done for the electric car in the public eye, I don’t mind if these batteries are simply normal batteries with nice window dressing.

    I think the advantages come with the need for power. When you stack 9 Tesla batteries versus 90 deep cycle batteries, you tend to see more advantages in space needed , and as it stated in this article” Larger capacity batteries of infinitely-scaleable capacity will be available to large businesses and governments” so when space is not an issue and the power demand is not so high.Then deep cycle batteries cannot be beat for the cost savings. But ,when you can have one battery that replaces a room full of batteries. especially when that room could be producing money. it is a big deal.


    We average $1600 – $2300 month electric bills. On top of our 30k solar panel system output and credits.
    Still a long way to go until these battery units will be worth the expense. But Tesla has already reduced the replacement cost of hybrid car batteries by $2k. So optimism is high amongst cultivators.

  8. Johnny… you have an interesting biography. How do I contact you by e-mail if I don’t use the MS Outlook Express that pops up every time I try to e-mail you?

  9. This version will probably going to be marketed to those that are willing to pay for slick, professional installations, not DIY-types. The early buyers of this product would rather be playing golf than rigging batteries for themselves. Of course, skilled makers will quickly figure out how the make the same storage system for half the cost. Either way, it’s a good thing. One thing to consider: LEDs take a LOT less energy than the older grow lights and might be a better match for battery systems.

  10. Hmm… $3500 for a 10kwH battery bank…

    You can get a deep-cycle, maintenance-free AGM battery with a 20-year shelf-life (an upgrade from ordinary lead-acid batteries) that holds 1.2kwH of power for about $300. It’s not hard to wire up multiple batteries into a single battery bank with the desired voltage if you know what you’re doing. 1.2kwH x 10 = 12kwH, $300 x 10 = $3000.

    Unless these batteries are using some astoundingly advantageous technology, I don’t see the cost benefit. Maybe the charge controller is built in, already? The market’s way of doing “high voltage for dummies,” perhaps?

    By all means, let’s hype renewable energy! However, let’s make sure the math is there, first.
