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.

U.S. moving fast to secure access to critical minerals to counter China’s dominance of market, Pentagon says

U.S. moving fast to secure access to critical minerals to counter China's dominance of market, Pentagon says

MP Materials CEO on deal with the Defense Department

The Pentagon is taking immediate action to boost critical mineral production in the U.S. and counter China’s dominance of the supply chain for rare earth magnets, a defense official told CNBC on Tuesday.

The Defense Department last week agreed to buy a direct equity stake in MP Materials, which will make the U.S. government the miner’s largest shareholder. MP operates the only rare earth mine in the U.S. located at Mountain Pass, California, and a magnet plant in Forth Worth, Texas.

When asked whether the Pentagon is considering similar investments in other U.S. mining companies, the defense official said it is looking at opportunities to strengthen domestic critical mineral production.

“Rebuilding the critical minerals and rare earth magnet sectors of the U.S. industrial base won’t happen overnight, but DoD is taking immediate action to streamline processes and identify opportunities to strengthen critical minerals production,” official said in a statement.

Rare earths are used in weapons such as the F-35 warplane, drones and submarines among other other military platforms. The U.S. was almost entirely dependent on foreign countries for rare earths in 2023, with China representing about 70% of imports, according to the U.S. Geological Survey.

MP Materials CEO James Litinsky told CNBC last week that he views the public-private partnership with the Defense Department as a model for other companies in industries that are important for national security but struggle to compete against the state-backed enterprises in China.

“I’d like to think that this is sort of the first, it’s a model,” Litinsky told CNBC’s “Squawk on the Street” on Thursday. “We have to deliver at MP and show that this is an incredible route to go. But it’s a new way forward to accelerate free markets, to get the supply chain on shore that we want.”

Interior Secretary Doug Burgum said in April that the U.S. government was looking at taking direct equity stakes in critical mineral and rare earth miners to break China’s dominance. The Trump administration is also looking at stockpiling critical minerals and creating a sovereign risk insurance fund to protect companies investments’ in federally approved projects, Burgum said at an energy conference in Oklahoma City.

The Pentagon makes long-term investments in mining, processing and refining critical minerals, the defense official told CNBC. It has invested $540 million so far to support a critical mineral and rare earth supply chain in the U.S. and allied nations, the official said.

“That is significant, and DoD will continue to such efforts in accordance with congressional appropriations and statutory authorities,” the official said.

Fairshake, the cryptocurrency industry’s most powerful political action committee, announced Tuesday that it now holds more than $141 million in cash on hand, underscoring the sector’s growing influence as Congress takes up landmark legislation this week.

The total, which includes liquid assets like crypto, stock, and cash, reflects a surge of donations from digital asset executives and firms, including a fresh $25 million from Coinbase.

Fairshake and its two affiliated PACs — Defend American Jobs and Protect Progress — have raised $109 million since Election Day in 2024 and $52 million during just the first half of this year.

“We are building an aggressive, targeted strategy for next year to ensure that pro-crypto voices are heard in key races across the country,” said spokesperson Josh Vlasto.

Ethereum succeeded beyond anyone's expectations, says network co-founder Vitalik Buterin at EthCC

The announcement lands in the middle of what lawmakers are calling “Crypto Week” on Capitol Hill, as the House begins deliberations on a trio of long-awaited bills that would define how digital assets are regulated.

The legislation includes the dividing of oversight, setting new stablecoin rules, and a bill banning the creation of a central bank digital currency.

The crypto industry is no longer just lobbying for survival, it is shaping the political landscape. Fairshake saw nearly every candidate it backed in 2024 win their race.

“We stuck to our core strategy from Day 1,” Fairshake previously told CNBC. “We supported pro-crypto candidates and opposed those who played politics with jobs and innovation, and won.”
