Tesla has released a new comparison report claiming Powerwall with solar is cheaper than a traditional backup generator.

For years now, Tesla has enjoyed a giant backlog of Powerwall orders, but now that production has ramped up, the automaker has worked through most of that backlog, and it has to start generating more demand for the home energy storage product.

Tesla has now released a new report that compares Powerwalls as a backup system to backup generators.

The company claims that when combining a Powerwall with solar, the backup system is cheaper than a traditional generator:

When paired with solar, Powerwall works daily to reduce your monthly electricity bill. Over ten years, these savings can make Powerwall and solar more cost effective than a generator.

Tesla says that you can save about $20 per month on payments when accounting for electricity bill savings and that overall, the system can cost up to 20% less over 10 years:

Tesla also lists a bunch of other advantages of Powerwalls over backup generators:

Differences Between Powerwall and Backup Generator

Powerwall Backup Generator
Experience Automatic, < 1 second transition to back up, without interruption 15-30 second delay, before automatic or manual backup
Energy Source Stored electricity from solar panels or the grid Natural gas, liquid propane or diesel
Noise Quiet (< 40 dBA at 1 meter) Louder (77 dBA at 1 meter)
Installation Indoors or outdoors, wall-mounted or floor-mounted Outside, generally on concrete pad, due to odor and exhaust
Maintenance Minimal Refuel, servicing and oil changes

Electrek’s Take

It’s important to note here that a Powerwall is cheaper than a generator after accounting for the savings that come with solar and the cost of fueling the generator.

When you look at the direct cost of both, a generator is cheaper. A single Tesla Powerwall starts at $8,400 and a 10 kW costs about $2,000 – both before installation.

Then, when you add solar, it adds to the price, but you start having significant savings on your electricity bill on top of having backup power.

I have two Powerwalls, and I absolutely love them. It’s a great product, but I understand it’s not a cheap product accessible to anyone. A generator can be cheaper.

I found this cheap Chinese e-cargo trike that hauls more than your car!

I found this cheap Chinese e-cargo trike that hauls more than your car!

If you’ve ever wondered what happens when you combine a fruit cart, a cargo bike, and a Piaggio Ape all in one vehicle, now you’ve got your answer. I submit, for your approval, this week’s feature for the Awesomely Weird Alibaba Electric Vehicle of the Week column – and it’s a beautiful doozie.

Feast your eyes on this salad slinging, coleslaw cruising, tuber taxiing produce chariot!

I think this electric vegetable trike might finally scratch the itch long felt by many of my readers. It seems every time I cover an electric trike, even the really cool ones, I always get commenters poo-poo-ing it for having two wheels in the rear instead of two wheels in the front. Well, here you go, folks!

Designed with two front wheels for maximum stability, this trike keeps your cucumbers in check through every corner. Because trust me, you don’t want to hit a pothole and suddenly be juggling peaches like you’re in Cirque du Soleil: Farmers Market Edition.

To avoid the extra cost of designing a linked steering system for a pair of front wheels, the engineers who brought this salad shuttle to life simply side-stepped that complexity altogether by steering the entire fixed front end. I’ve got articulating electric tractors that steer like this, and so if it works for a several-ton work machine, it should work for a couple hundred pounds of cargo bike.

Featuring a giant cargo bed up front with four cascading fruit baskets set up for roadside sales, this cargo bike is something of a blank slate. Sure, you could monetize grandma’s vegetable garden, or you could fill it with your own ideas and concoctions. Our exceedingly talented graphics wizard sees it as the perfect coffee and pastry e-bike for my new startup, The Handlebarista, and I’m not one to argue. Basically, the sky is the limit with a blank slate bike like this!

Sure, the quality doesn’t quite match something like a fancy Tern cargo bike. The rim brakes aren’t exactly confidence-inspiring, but at least there are three of them. And if they should all give out, or just not quite slow you down enough to avoid that quickly approaching brick wall, then at least you’ve got a couple hundred pounds of tomatoes as a tasty crumple zone.

The electrical system does seem a bit underpowered. With a 36V battery and a 250W motor, I don’t know if one-third of a horsepower is enough to haul a full load to the local farmer’s market. But I guess if the weight is a bit much for the little motor, you could always do some snacking along the way. On the other hand, all the pictures seem to show a non-electric version. So if this cart is presumably mobile on pedal power alone, then that extra motor assist, however small, is going to feel like a very welcome guest.

The $950 price is presumably for the electric version, since that’s what’s in the title of the listing, though I wouldn’t get too excited just yet. I’ve bought a LOT of stuff on Alibaba, including many electric vehicles, and the too-good-to-be-true price is always exactly that. In my experience, you can multiply the Alibaba price by 3-4x to get the actual landed price for things like these. Even so, $3,000-$4,000 wouldn’t be a terrible price, considering a lot of electric trikes stateside already cost that much and don’t even come with a quad-set of vegetable baskets on board!

I should also put my normal caveat in here about not actually buying one of these. Please, please don’t try to buy one of these awesome cargo e-trikes. This is a silly, tongue-in-cheek weekend column where I scour the ever-entertaining underbelly of China’s massive e-commerce site Alibaba in search of fun, quirky, and just plain awesomely weird electric vehicles. While I’ve successfully bought several fun things on the platform, I’ve also gotten scammed more than once, so this is not for the timid or the tight-budgeted among us.

That isn’t to say that some of my more stubborn readers haven’t followed in my footsteps before, ignoring my advice and setting out on their own wild journey. But please don’t be the one who risks it all and gets nothing in return. Don’t say I didn’t warn you; this is the warning.

OPEC+ members agree to larger-than-expected oil production hike in August

OPEC+ members agree to larger-than-expected oil production hike in August

Eight oil-producing nations of the OPEC+ alliance agreed on Saturday to increase their collective crude production by 548,000 barrels per day, as they continue to unwind a set of voluntary supply cuts.

This subset of the alliance — comprising heavyweight producers Russia and Saudi Arabia, alongside Algeria, Iraq, Kazakhstan, Kuwait, Oman and the United Arab Emirates — met digitally earlier in the day. They had been expected to increase their output by a smaller 411,000 barrels per day.

In a statement, the OPEC Secretariat attributed the countries’ decision to raise August daily output by 548,000 barrels to “a steady global economic outlook and current healthy market fundamentals, as reflected in the low oil inventories.”

The eight producers have been implementing two sets of voluntary production cuts outside of the broader OPEC+ coalition’s formal policy.

One, totaling 1.66 million barrels per day, stays in effect until the end of next year.

Under the second strategy, the countries reduced their production by an additional 2.2 million barrels per day until the end of the first quarter.

They initially set out to boost their production by 137,000 barrels per day every month until September 2026, but only sustained that pace in April. The group then tripled the hike to 411,000 barrels per day in each of May, June, and July — and is further accelerating the pace of their increases in August.

Oil prices were briefly boosted in recent weeks by the seasonal summer spike in demand and the 12-day war between Israel and Iran, which threatened both Tehran’s supplies and raised concerns over potential disruptions of supplies transported through the key Strait of Hormuz.

At the end of the Friday session, oil futures settled at $68.30 per barrel for the September-expiration Ice Brent contract and at $66.50 per barrel for front month-August Nymex U.S. West Texas Intermediate crude.
