From my residence in Los Angeles, I witnessed the devastation of wildfires earlier this 12 months and the way they underscored the rising urgency to modernize water infrastructure. A slew of harmful chemical compounds have been launched into Los Angeles’ ingesting water and stormwater methods in the course of the wildfires, leaving many communities involved about whether or not their water was protected to drink.
These wildfires shone a lightweight on whether or not our water methods are outfitted to deal with disasters. As wildfires develop extra frequent and intense, it turns into much more pressing to adapt our water infrastructure to fulfill this new actuality. A lot of the nation’s water infrastructure is nearing the tip of its lifespan. And but, modernizing ingesting and wastewater methods may exceed $744 billion in prices over the subsequent 20 years.
Between the pressing have to improve decades-old methods and the rising impacts of climate-driven climate extremes, the huge networks of pipes, remedy crops, and drainage methods throughout the U.S. are beneath immense pressure.
Uncertainty round laws and funding
Federal and state laws and funding may put a major dent in addressing important water infrastructure wanted to assist financial progress and communities. The Bipartisan Infrastructure Regulation, for instance, earmarks $50 billion for water, wastewater, and stormwater infrastructure upgrades. As of November, about $41 billion had been awarded for the measure, which garnered broad enterprise assist.
States, in the meantime, even have pushed for water infrastructure enhancements. Final 12 months, California voters approved $10 billion in spending on environmental tasks, with practically $4 billion for tasks devoted to enhancing water high quality and defending the state from floods and droughts and restoring rivers and lakes.
However there may be rising uncertainty surrounding such funding as a result of dynamic state of affairs in Washington. As this performs out, it’s essential for corporations and traders to make the most of non-public sector alternatives to drive innovation, partnerships and investments in climate-resilient water infrastructure.
This work strengthens water provides for companies and fuels financial exercise: investments in new and improved water methods may yearly contribute greater than $220 billion to the U.S. financial system and create about 1.3 million new jobs.
Personal sector alternatives
For a lot of a long time, municipal bonds have been a important device for shoring up water infrastructure. At the moment, inexperienced bonds can provide traders a strong alternative to finance water and wastewater administration tasks that promote local weather adaptation and resiliency. Certification frameworks such because the Local weather Bonds Initiative present standards making certain these investments go towards water infrastructure tasks aligned with environmental objectives.
Firms — from information facilities to agriculture — that want clear water to function even have a task to play in making certain the water methods they rely upon are dependable and constructed to endure climate extremes. This shared curiosity in resilient water infrastructure presents a possibility for companies to work with friends, governments and different stakeholders on tasks that stop water service disruptions and better prices to companies and communities.
Shifting previous conventional approaches
As we work to strengthen our water infrastructure system to fulfill a brand new local weather actuality, we should additionally suppose past conventional approaches. Nature-based water methods and options can play a important function in managing water and restoring and defending ecosystems inside watersheds that assist filter and transport clear water. Holistic approaches corresponding to wetland safety and restoration assist strengthen water methods towards the rising pressures of maximum climate.
Some corporations are leveraging partnerships to speed up and broaden the affect of those options. Olam, a meals substances and agri-business firm, has partnered with the USDA Forest Service, Nationwide Forest Basis, and Knorr (a Unilever Model) on restoration tasks to enhance resilience, together with potential impacts of extreme wildfire, in California’s Pine Flats watershed.
By way of the California Water Resilience Initiative, corporations corresponding to Ecolab and Common Mills are working with the Pacific Institute to construct company assist for tasks and insurance policies addressing strained water sources within the state, together with efforts to revive ecosystems.
Firms can even assist federal insurance policies that assist modernize water infrastructure. International water know-how firm Xylem, for instance, lobbied for the 2016 passage and implementation of the Water Infrastructure Enhancements for the Nation Act (WIIN Act), which offers grants to enhance infrastructure resiliency in deprived communities.
The Los Angeles fires are simply the most recent instance of how local weather disasters are pushing America’s ageing water methods to the brink. We want an all hands-on deck method, with revolutionary options and funding, to improve and substitute the nation’s community of water infrastructure on the tempo and scale that ensures the long-term well being and security of communities and the financial system.
To counter the gloom and doom over Tesla’s falling EV gross sales, a motion is afoot to make EV-hating conservatives purchase a brand new Tesla, as if they might neglect in a single day how a lot they hate EVs. Good luck with that. In the meantime, Tesla gross sales present no signal of selecting up, Tesla inventory took one other dip at this time, and the competitors has noticed a ripe alternative to promote extra EVs. That features Common Motors, which doubling down on its house EV charging pitch.
How Low Can Tesla Go?
CleanTechnica has been monitoring the ups and downs of Tesla since 2008. Just lately it’s been extra downs than ups. You’ll be able to atone for all of the outdated information right here and scoot proper on as much as Monday, March 17, when Tesla inventory took yet one more nosedive, and notably so. Regardless of the financial uncertainties foisted up on markets by the dictator-adjacent Commander-in-Chief who occupies the Oval Workplace, shares went up on Friday they usually continued their upwards trajectory on Monday, whereas Tesla slid down, down, down by nearly 5%.
Tesla’s under-performance in opposition to the markets parallels its latest EV gross sales report, which has additionally spiraled downwards whilst world EV gross sales proceed to rise. Final week the Commander-in-Chief himself took outing from destroying the US authorities to transform the White Home right into a QVC set, in a nakedly determined try to assist Tesla CEO Elon Musk promote vehicles.
Don’t fear, the Chief of the Free World gained’t get in bother for promoting stuff on the White Home garden. Everyone is aware of the President is exempt from the Hatch Act. He’ll be awfully busy promoting vehicles for the following subsequent 3-3/4 years, although. Final week Musk additionally pledged to churn out twice the variety of Teslas within the US. Because the libs gained’t purchase them any extra, Trump should make his pitch to conservatives, who’ve spent the previous 15 years slinging mud at the automobile electrification motion.
GM Has A Dwelling EV Charging Deal For You
BMW and Toyota are among the many automakers making hay out of Tesla’s missteps. Each are introducing new EVs and new EV ideas to the European market to fill the EV gross sales hole left by Tesla. Right here within the US, Common Motors is among the many automakers in search of an edge, and the corporate is focusing like a thousand factors of sunshine on forging new EV charging relationships with utilities.
In case you’re pondering house EV charging and digital energy vegetation are in play, run proper out and purchase your self a cigar. Dwelling EV charging gives EV house owners with new alternatives to take part within the rising VPP economic system, and that’s the place GM is goals to beat the competitors to the punch.
Particularly, GM is trialing a VPP mission with EV drivers in California, which is one other key market wherein Tesla gross sales have dropped in latest months, whilst total EV gross sales have risen. Coincidentally or not, final week the chief income officer of GM’s Vitality department, Aseem Kapur detailed the corporate’s new house EV charging promotion with the California utility PG&E, which has been rolling out a “Automobile-to-Every little thing” pilot program.
Kapur lower straight to the chase, reminding GM prospects they’ll can rise up to $4,500 off the worth of GM Vitality bidirectional house charging gear in the event that they enroll within the PG&E program.
“The product expertise and the worth for patrons doesn’t finish when a GM EV is parked,” Kapur additionally emphasised, which brings up a key level. Most vehicles spend most of their stay sitting round in Park, not doing something in any respect. Bidirectional charging can put them to work simply standing nonetheless.
As famous by Kapur, probably the most quick and invaluable use case is to deploy the EV battery to run lights and different electrical gear at house if the grid connection is misplaced. The digital energy plant angle kicks in when EV house owners use their parked vehicles to provide vitality to the grid throughout peak use durations when charges are excessive. They’ll additionally time-shift their charging schedule to make the most of low off-peak charges, doubtlessly making themselves some cash on the distinction.
“Whereas giving prospects the flexibility to make use of their GM EV as a back-up house generator is an unimaginable, sensible profit to prospects, it’s only the start of what we are able to do to assist encourage mass EV adoption with this know-how,” Kapur enthuses.
Underneath the pilot program, GM and PG&E anticipate accumulating sufficient information to optimize the combination of house EV charging methods with digital energy vegetation. Other than the potential for direct monetary advantages to the EV proprietor, VPPS might help utilities keep away from the price of constructing new gasoline “peaker” vegetation for high-demand durations.
Spreading The Dwelling EV Charging Message Throughout The US
The pilot program is out there solely to PG&E’s prospects in Northern California, however Kapur is already trying ahead to uptake on a broad scale, as vitality stakeholders in different states pursue a extra resilient, versatile distributed vitality sources mannequin. As GM sees it, house EV charging is of apiece with photo voltaic vitality and different scalable, distributed types of clear tech.
“With the precise incentives and insurance policies in place, packages like this one might speed up the shift towards a extra distributed vitality mannequin,” Kapur observes. “As different states discover methods to fulfill renewable vitality targets, Automobile-to-Dwelling, Automobile-to-Grid and VPP know-how provide a strong resolution that may assist scale back pressure on energy vegetation, improve using photo voltaic vitality, and provides shoppers extra management over their vitality prices sooner or later.”
The California pilot program is only for starters. “GM Vitality is working with utilities and aggregators throughout the nation to discover how EVs can improve grid resilience, vitality safety, and in the end EV adoption,” Kapur provides.
“As we proceed to innovate and increase our bidirectional charging and vitality administration capabilities, we’re laying the groundwork for a future the place EVs should not simply automobiles however very important elements of a cleaner, extra dependable vitality system,” he concludes.
That just about sums it up. Trump’s order disabling EV charging stations at federal buildings was an obnoxious act of spite and an enormous waste of taxpayer {dollars} that can have a restricted impact, if any, on EV gross sales over the long term. Trump additionally stabbed US automakers within the again when he unplugged the $5 billion NEVI public charging program in midstream, solely not fatally. Personal sector stakeholders are busy selecting up the charging station slack already.
Trump or not, the EV revolution is right here to remain. GM and different US automakers have been right here lengthy earlier than Trump grifted his manner into the White Home. They’ll be right here lengthy after he leaves, with the attainable exception of Tesla.

The newest Palo Alto Networks Unit 42 Cloud Menace Report discovered that delicate knowledge is present in 66% of cloud storage buckets. This knowledge is weak to ransomware assaults. The SANS Institute lately reported that these assaults will be carried out by abusing the cloud supplier’s storage safety controls and default settings.
“In simply the previous few months, I’ve witnessed two totally different strategies for executing a ransomware assault utilizing nothing however official cloud security measures,” warns Brandon Evans, safety marketing consultant and SANS Licensed Teacher. Halcyon disclosed an assault marketing campaign that leveraged certainly one of Amazon S3’s native encryption mechanisms, SSE-C, to encrypt every of the goal buckets. Just a few months prior, safety marketing consultant Chris Farris demonstrated how attackers might carry out the same assault utilizing a special AWS safety characteristic, KMS keys with exterior key materials, utilizing easy scripts generated by ChatGPT. “Clearly, this matter is top-of-mind for each menace actors and researchers alike,” notes Brandon.
To deal with cloud ransomware, SANS recommends organizations to:
Perceive the ability and limitations of cloud safety controls: Utilizing the cloud doesn’t routinely make your knowledge secure. “The primary cloud providers most individuals use are file backup options like OneDrive, Dropbox, iCloud, and others,” explains Brandon. “Whereas these providers normally have file restoration capabilities enabled by default, this isn’t the case for Amazon S3, Azure Storage, or Google Cloud Storage. It’s important for safety professionals to know how these providers work and never assume that the cloud will save them.”
Block unsupported cloud encryption strategies: AWS S3 SSE-C, AWS KMS exterior key materials, and related encryption strategies will be abused as a result of the attacker has full management over the keys. Organizations can use Identification and Entry Administration (IAM) insurance policies to mandate the encryption methodology utilized by S3, equivalent to SSE-KMS utilizing key materials hosted in AWS.
Allow backups, object versioning, and object locking: These are a few of the integrity and availability controls for cloud storage. None of them are enabled by default for any of the Huge 3 cloud suppliers. If used correctly, they will improve the probabilities that a company can recuperate its knowledge after a ransomware assault.
Stability safety and value with knowledge lifecycle insurance policies: These security measures price cash. “The cloud suppliers aren’t going to host your knowledge variations or backups totally free. On the similar time, your group shouldn’t be going to offer you a clean test for knowledge safety,” says Brandon. Every of the Huge 3 cloud suppliers permits prospects to outline a lifecycle coverage. These insurance policies permit organizations to routinely delete objects, variations, and backups when they’re not thought of needed. Bear in mind, nonetheless, that attackers can leverage lifecycle insurance policies as properly. They had been used within the beforehand talked about assault marketing campaign to induce the goal to pay the ransom rapidly.
