After a summer of extreme weather and wildfires and now during the peak of hurricane season, the power going out again is becoming familiar to more Americans. That means it may be a good time to consider a home backup power storage system.

The pervasiveness of extreme weather and climate change, local utility reliability and cost may all factor into this financial decision.

“Backup power may be warranted depending on regional factors and geography as well as the state of the infrastructure there,” said Benjamin R. Dierker, executive director of the Alliance for Innovation and Infrastructure, a research and educational organization, in an email. 

In coastal areas, for instance, considerations include the resilience of storm or sea walls, the quality and capacity of drainage infrastructure and the electrical grid’s hardiness, he said. In other areas, extreme weather conditions like high winds, tornados and ice may cause falling trees or downed lines — a risk that’s significantly mitigated if there are buried utility lines rather than overhead lines, Dierker said. Pre-emptive shutdowns, due to extreme weather or other factors, can also be a consideration.

As of Sept. 11, there have been 23 confirmed weather/climate disaster events with losses exceeding $1 billion each to affect United States, according to the National Centers for Environmental Information, which has a graphic that shows the locations of these disasters. These events included two flooding events, 18 severe storm events, one tropical cyclone event, one wildfire event, and one winter storm event. 

Here’s what consumers need to consider about home back-up power options:

Appliance needs during power outages

A good first step is to think about the most important appliances you are running on electricity and how long you might realistically need them to run in the event of an outage, said Vikram Aggarwal, chief executive and founder of EnergySage, which helps consumers compare clean home energy solutions.

If you have minimal backup needs, a small portable fossil-fuel generator or battery could suffice, which can cost a few hundred dollars. But if you want your home to operate as normal, you’ll want to consider whole home options.

Location can be a factor since in some areas, the power goes out infrequently or for only short periods of time. In some states like California, Texas and Louisiana, however, it can be a whole different ball game. California consumers, for example, can get an up-to-date sense of outages in their area to get a sense of what their risk may be.

Fossil fuel vs. battery power

If you’re not opposed to fossil fuel-powered options, there are several categories to consider based on your power needs. For lower power needs, a portable generator, which often runs on gasoline or diesel can cost a few hundred dollars to several thousand dollars. There are also higher-priced portable versions that are usually quieter and more fuel-efficient and may be able to power multiple large appliances—and for longer. How long depends in part on the appliances you’re powering.

A whole home standby generator, meanwhile, is permanently installed and automatically kicks on when the power goes out. This generator type is often fueled by propane or natural gas and costs vary based on size, brand and fuel type. There are options in the $3,000 to $5,000 range, but with installation the total can be considerably higher. This could be a good option if you’re expecting outages for multiple days; theoretically, the generator can run for as long as fuel is supplied, but it can be advisable to shut it down for engine-cooling purposes.

For the environmentally-inclined, battery-powered backups can be a good option for their more environmentally friendly and quieter nature. For a few hundred dollars, give or take, there are lower-priced smaller to mid-size battery options that people can purchase and that will last for several hours.

There are also battery-powered options to back up the whole home that offer many of the same functions as conventional generators, but without the need for refueling, according to EnergySage. Consumers might expect to pay $10,000 to $20,000 to install a home battery backup system, EnergySage said. This can often last for eight to 12 hours, or even longer if you aren’t using it to power items such as air conditioning or electric heat.

Incentives that lower the cost of purchase and installation

When thinking about what type of backup to choose, incentives can factor into the equation. Thanks to the Inflation Reduction Act, households can receive a 30% tax credit for a battery storage installation, even if it’s not paired with a solar system, Aggarwal said.

Other state and local incentives may also be available. For instance, in some markets like California, Vermont, Massachusetts and New York, utilities pay consumers to tap into their batteries during peak periods like the summer, Aggarwal said. Consumers with larger batteries—10kWh or more—may be able to earn hundreds of dollars a year, he said.

EVs as a backup power option for the home

Some electrical vehicles can be used to back up essential items, or, in some cases, a whole home.

Ford’s F-150 Lightning, for example, can power a home for three days, or up to 10 days under certain circumstances, according to the company. With the required system installed, and the truck plugged in, stored power is transferred seamlessly to the home in the case of a power outage. For its part, GM recently said it would expand its vehicle-to-home bidirectional charging technology to its entire lineup of Ultium-based electric vehicles by model year 2026.

In the past, Jim Farley, Ford CEO has spoken about how the F-150 Lightning’s abilities as a source of backup power for homes and job sites have been a real “eye-opener” for the automaker. 

“If you’re contemplating spending $10,000 on a whole home gas generator system, why not think about an EV with this capability instead?” said Stephen Pantano, head of market transformation at Rewiring America, a nonprofit focused on electrifying homes, businesses and communities.

Consumers in the market for a new stove might also consider an induction model with an integrated battery to power it or other items such a fridge on an as-needed basis, Pantano said. “This opens up new possibilities for power backups that weren’t there before.”  

Solar-plus-storage can lead to long-term savings

Home solar panels are becoming more popular, but most are connected to the grid, and you need some kind of battery storage in order to have backup power, said Sarah Delisle, vice president of government affairs and communications for Swell Energy, a home energy solutions provider.

That’s where a solar-plus-storage system can come in handy. It allows people to use electricity generated from their solar panels during the day at a later point, which can be particularly useful for people who live in areas where there are frequent power outages, said Ted Tiffany, senior technical lead at the Building Decarbonization Coalition, a group that promotes moving buildings off fossil fuels.

A solar-plus-storage system costs about $25,000 to $35,000, depending on the size of the battery and other factors, according to the U.S. Dept of Energy. It’s easier and more cost-effective to install panels and the battery at the same time, but it’s not required. Homeowners who have already installed solar panels and want to add storage, might expect to pay between $12,000 to $22,000 for a battery, according to the Energy Department. Consumers who purchase a battery on its own or with backup are eligible for federal tax credits. Some states provide additional solar battery incentives

Also consider the long-term savings potential, Tiffany said. He has a family member who, with electrical upgrades, spent around $8,000 on a fossil fuel-powered whole home generator. Putting that money into solar instead might have been more economical because of the energy savings over time and tax incentives, he said. 

Consumers can visit EnergySage to find contractors and get information about solar and incentives. They can also visit, Switch is On, which helps consumers find information on electrification and efficiency measures for home appliances that supports the renewable energy integration.

Rad’s ‘jack-of-all-trades’ RadRunner 2 and RadRunner 3 Plus e-bikes provide utility with mobility at low prices from $999

Having begun back in February, and now continuing with Rad Power’s current Earth Day Sale running through April 23, the brand still has two of its three RadRunner series e-bikes down at the lowest prices in their history, while the RadRunner Plus model has run out of stock. Starting with the lowest priced, you can hop aboard the brand’s RadRunner 2 Utility e-bike for just $999 shipped, bringing costs down from its $1,499 post-2024 tariff pricing. Before this price cut began, things had only ever fallen as low as $1,199 before the summer of last year, with discounts following July only ever dropping to $1,299. But with this shake-up, you’ll score $500 off the going rate for as long as supplies last, gaining a versatile means to commute and run errands at the lowest price we have tracked.

Given the moniker of Rad’s “jack-of-all-trades” model, the RadRunner 2 is an affordable means to get around during commutes, joyrides, errand running, and more. I see them, and their counterparts in the series, parked outside my local grocery store frequently, as more and more folks in Brooklyn seem to be finding them as a solid alternative to owning a car. You’ll get up to 50 miles of travel here with its four PAS levels activated at up to 20 MPH top speeds with its combination of a 750W brushless gear hub motor and the 672Wh battery. Along with the simplified control panel for its riding settings, it also comes stocked with a rear-mounted cargo rack that offers a 120-pound payload, puncture-resistant fat tires, a standard LED headlight, and an integrated taillight with both brake light and flash mode capabilities.

The upgraded RadRunner 3 Plus e-bike, meanwhile, is also still down at it’s newest all-time low of $1,699 shipped, brought down from $2,199. It sports the same 750W motor and 672Wh battery combination for achieving 45+ miles of travel through its five PAS levels at up to 20 MPH speeds. There are some notable differences here, like the Tektro hydraulic disc brakes that provide better stopping power (over the RadRunner 2’s mechanical ones), as well as a 350-pound payload (50 pounds more total), and a longer step-thru design for a more ergonomic riding position. There are also other features like puncture-resistant fat tires, fenders over both wheels, the LED headlight and brake-light capable integrated taillight (with the auto-on functionality), and LCD screen for settings.

EcoFlow’s latest flash sale gives you the multi-capable DELTA Pro 3 with four 125W solar panels at a new $2,999 low, more

As part of its ongoing Mega Sale through April 25, EcoFlow has launched the next round of its flash offers lasting through the rest of the day. The main deal here is the DELTA Pro 3 Portable Power Station bundled alongside four 125W solar panels for $2,999 shipped. Coming down off its usual $4,598 price tag, we’ve only ever seen discounts take it down as low as $3,199 before today. For the rest of the day, you can take advantage of this lower-than-ever pricing to score one of the brand’s newer solar generator packages at a 35% markdown, giving you $1,599 in savings at a new all-time low price. It even beats out Amazon, where it still sits $300 higher.

One of the brand’s newer models that has been quite popular since releasing back in June, the EcoFlow DELTA Pro 3 starts off with an already impressive 4,096Wh LiFePO4 battery capacity with a steady 4,000W of power output that surges up to 6,000W. It comes with some equally impressive expansion capabilities up to 48,000Wh with additional equipment, with its output also expanding up to 12,000W when three of these power stations are connected together, covering major home backup needs. Among the many units under the brand’s flag, this one offers the widest amount of ways to recharge its own battery, with seven solo options and 18 combination options. A standard wall outlet will have it back at an 80% battery in 50 minutes, while also offering other options like solar charging (with a max 2,600W input), EV, automotive auxiliary outlets, dual PV charging, and much more.

It’s been given 14 output ports, divided up amongst seven ACs, two USB-As, two USB-Cs, and three DCs, and offers up the complete array of smart controls accessed through the companion app to monitor and adjust settings as it keeps your devices and appliances running. It was the first unit to be given the latest X-Core 3.0 tech, expanding its surging capabilities and charging speeds while also running at quieter decibels and cooler temperatures, as well as improving upon the battery and smart home management, providing “explosion-proof” battery packs, and upgrading its parallel capacity expansion performance.

The second of today’s flash savings gives you the brand’s 800W Alternator Charger at $349 shipped, coming down from its regular $399 pricing during this sale and its full $599 rate. With this device, you’ll be able to recharge any power station you have via your car’s alternator, juicing the battery back up while on the move – which makes a perfect companion for those who may be taking their setups on the road.

Tesla Odometergate: is it Tesla’s own Dieselgate or nothing burger?

Tesla Odometergate: is it Tesla's own Dieselgate or nothing burger?

A lawsuit alleging that Tesla is inflating mileage to avoid warranty claims is already being compared to Dieselgate and referred to as ‘Tesla Odometergate.’

Is Tesla having its own Dieselgate, or is it a nothing burger?

A new class action lawsuit filed in California against Tesla alleges that the automaker is using “predictive algorithms” to inflate mileage at the odometers, allowing Tesla to claim higher mileage past warranty limits.

Lawyers for the plaintiff wrote in the lawsuit:

Rather than relying on mechanical or electronic systems to measure distance, Plaintiff alleges on information and belief that Tesla Inc. employs an odometer system that utilizes predictive algorithms, energy consumption metrics, and driver behavior multipliers that manipulate and misrepresent the actual mileage travelled by Tesla Vehicles. In so doing, Defendants can, and do, accelerate the rate of depreciation of the value of Tesla Vehicles and also the expiration of Tesla Vehicle warranties to reduce or avoid responsibility for contractually required repairs as well as increase the purchase of its extended warranty policy.

The lawsuit refers to patents filed by Tesla regarding its mileage counter, but it primarily relies on the experience of its lead plaintiff.

Nyree Hinton, a data professional from Los Angeles, is the lead plaintiff in the lawsuit and shared his own experience that led to making these allegations.

In December 2022, Hinton purchased a used 2020 Tesla Model Y with 36,772 miles on the odometer. He received Tesla’s Basic Vehicle Limited Warranty, which covers repairs for four years or 50,000 miles, whichever comes first.

Shortly after, Hinton noticed that his vehicle’s mileage increased at an unexpected rate. Despite driving approximately 20 miles per day, based on his own estimate, the odometer indicated an average of over 72 miles per day. This rapid mileage accumulation led to the warranty expiring sooner than anticipated, resulting in Hinton incurring a $10,000 suspension repair bill that he believed should have been covered under the warranty otherwise.

Other than Hinton’s experience, the lawsuit is light on data, but it does cite other Tesla owners claiming to have similar experiences on forums and social media.

Here’s the full lawsuit:

Tesla’s own Dieselgate or a nothing burger

If the allegations in this lawsuit are factual, it would indeed be a significant scandal. However, it is light on proof.

Hinton appears to have closely tracked his own experience, and he has some credibility as a data analyst. We have no reason not to believe him, but the case would need a lot more evidence to move forward.

Electrek reached out to ‘Green’, a well-known Tesla hacker who frequently discovers new features and specifications in Tesla’s software and firmware.

He told us that he doubts Tesla would have been able to hide something like that from him and the broader whitehat hacking community, but he admits they weren’t looking for it.

Green believes that it is likely that Tesla uses predictive algorithms for its odometer, but it could be as simple as accounting for tire wear, since tire rotation is used to calculate odometer mileage.

Odometers are not perfect, and there can be some discrepancies, but the one described by the lead plaintiff in this case is undoubtedly higher than what would be expected or allowed.

Electrek’s Take

I think it’s too light on data and proof right now to make a big deal out of this. I have no reason not to believe Hinton, but it could also be a specific problem with his vehicle rather than a broader issue and active deception from Tesla.

If the lawsuit is allowed to proceed, we may gain more insight, and it could encourage others with similar experiences to join in – resulting in more data.

In the meantime, I’ll remain in the skeptical camp on this one.

Tesla (TSLA) brand damage is destroying used car value: ‘People don’t want them anymore’

Tesla (TSLA) brand damage is destroying used car value: 'People don't want them anymore'

Tesla’s brand damage is eroding the value of used Tesla vehicles at a rapid rate, as owners rush to sell theirs.

It is breaking the used Tesla market as prices are plunging just as the broader used car market is recovering.

After a few tough years for the used car market following the pandemic, it is finally starting to recover over the last month.

Economic uncertainty and a fear of higher inflation due to Trump’s tariffs are prompting some buyers to shift from the new car market to the used car market.

From March 2024 to March 2025, average used car prices decreased by 2.68% in the US, but the trend has finally reversed.

According to Car Guru‘s used car index, used car prices have risen an impressive 2.17% in the last 30 days alone.

However, there’s an exception: Tesla.

The price of used Tesla vehicles has been falling, like the rest of the used car market, since the pandemic; however, it is not benefiting from the reversal in the current macroeconomic situation.

While average used car prices rose more than 2% in the last 30 days, Tesla’s used car prices decreased by 1.34% in the US.

That’s due to oversupply, as many Tesla owners are selling their vehicles to distance themselves from the Tesla brand, which is associated with CEO Elon Musk and his increasingly divisive political views.

The demand to sell used Tesla vehicles is so high that many used car dealers, who had been fighting to acquire inventory just a year prior, are starting to be reticent about buying Tesla vehicles as the value decreases so rapidly.

In Quebec, Le Journal de Montréal spoke with local used car dealers and attended a car auction where many Tesla vehicles were up for sale, with some selling for half the price they were selling for just over a year ago.

Éric Piuze, owner of a used car dealership on Montreal’s South Shore, said (translated from French):

“People don’t want them anymore. The Elon Musk effect is very real in Quebec.”

The used car dealers at the auction noted that they are not confident they can sell the used Tesla quickly enough to avoid further value decreases.

Furthermore, they note that potential buyers are lowballing on Tesla vehicles because they are aware that inventory is high, creating a buyer’s market.

Dealers are also seeing higher defaults on Tesla car payments, as buyers who took on debt to purchase them just a few years ago struggle to make payments.

Piuze added (translated from French):

People paid a lot of money for Teslas. During the pandemic, we saw many people remortgaging their homes to buy a Tesla. Those days are over.

At its peak, the average used Tesla price was over $60,000 in 2022. Now, the same vehicles are worth a fraction, but their car payments are still high.

Electrek’s Take

Even with the used car market finally getting a breather from crashing prices, Tesla vehicles are not benefiting at all. This highlights a significant issue in the used Tesla market. It’s broken.

The market can’t absorb the surge in people selling their Tesla vehicles.

I wouldn’t want to be a company holding a fleet of Tesla vehicles right now. The value erosion is impressive.

I thought that maybe the Cybertruck was dragging the entire Tesla market down, with a 6.64% decrease in used value over the last 30 days. However, the Model Y alone saw a 1.67% decrease during the same period.

The good news is that the vast majority of people selling their used Tesla vehicles are purchasing other electric vehicles, thereby boosting the EV market. It’s also giving people the chance to get into Tesla vehicles for cheaper, although they should expect the value of those vehicles to decrease rapidly.
