Income inequality is palpable on the streets of the United States in cities and towns alike. On one block you may have neighborhoods with maintained roads and sidewalks, well-funded schools, and easy access to services including grocery stores, transit, healthcare, and banks. And on the next block you may have neighborhoods in transit or food deserts with vulnerable key infrastructure including streets, schools, and healthcare.
This checkerboard-like phenomenon becomes ever more apparent after a disaster, as communities with less resources wait, often literally in the dark, while construction crews and vehicles go first to the areas with more.
This was especially visible in Puerto Rico after Hurricane Maria, which struck four years ago on September 20, when communities endured the longest power outage in US history. Public aid for many lower- and middle-income communities was both insufficient and slow. That is why RMI and partners* formed the Puerto Rico Community Energy Resilience Initiative (CERI).
CERI’s goal is to advance access to reliable and renewable energy for critical facilities in low-to-moderate income communities using solar plus storage microgrids. Under a broader definition of critical facility, examples include hospitals and fire stations, local life-sustaining businesses, and non-profits providing essential services following disasters.
The CERI team spent a year working on pilot projects, community engagement, and financing vehicle development. In the end, the team found that a community-driven process combined with flexible capital and technical assistance is the most effective way to help achieve energy resilience for those whose needs are not served in the current market.
The CERI team on site at one of the critical facilities: Farmacia Jomari in rural Puerto Rico. During power outages after Hurricane Maria, the pharmacy provided critical health & financial services to local community members.
Putting All Communities in the Driver’s Seat
CERI puts Puerto Rican communities that received limited aid after disasters in the driver’s seat. The team does this by first listening to community stakeholders and then addressing their energy resilience needs by preparing and de-risking the project. CERI then uses a blend of capital from financial institutions and philanthropic organizations to advance access to reliable and renewable energy.
Currently, the CERI team is installing four pilot projects at critical facilities: two nonprofit organizations and two local businesses, with systems averaging approximately 63 kW of solar and 30 kWh of storage. The pilot projects highlight the importance of community ownership of systems, flexibility in designing a project’s financing, and timing for engaging different stakeholders.
When microgrid projects are locally owned, community members autonomously create their energy goals while simultaneously bolstering local economies and jobs. Facility leaders can determine which equipment and operations must continue during an outage based on their own experiences. This bottom-up involvement shifts accountability from external programs to the community itself.
Flexible Financing Adapts to Community Needs
It is crucial to have financing models that are scalable yet able to flex to individual project constraints. The CERI team will soon launch a financing vehicle which will provide critical facilities throughout the island with concessionary capital and technical assistance needed to simultaneously make systems more affordable and make financing viable.
Operationally, this equates to a lower interest rate and a shorter term on the loan used to pay for the facility’s microgrid. This grant funding contributes to the system’s down payment and to the creation of a loan loss reserve for financial institutions to allow facilities with varying credit histories to access competitive interest rates.
The CERI team’s initial vision was to award a project with an amount of grant funding so that the microgrid’s estimated monthly costs over a 10-year period would be less than the facility’s average monthly energy bill. Monthly costs include loan payments, maintenance, insurance costs, and fixed fees to the utility.
Although some facility staff prioritized the lower monthly energy costs, other facility managers were willing to pay more to reduce their loan term. Such scenarios highlighted the need for the CERI team to work with financial institutions to offer flexibility in the loan’s terms and/or payment options that do not penalize early payments.
Syncing Timelines of Multiple Stakeholders
From a timeline perspective, as the CERI team scales up, the team will ensure to use an inclusive and fair process for project recruitment and selection. This includes engaging with all types of communities (rural and urban, for example) and maintaining transparency with interested facilities.
Once projects are selected, CERI team members will be diligent to engage all the project’s stakeholders early in the project development process and use a competitive process whenever possible to find savings for the participating organizations. Such stakeholders include local financial institutions, local microgrid developers, and critical facility staff. These stakeholders have varying amounts of staff available to focus on a specific microgrid project and differing due diligence and review processes.
For example, financial institutions assess the facility’s financial history, developers build systems based on the facility staff’s requirements, and the facility staff decide whether to take a loan depending on costs and loan terms. If not lined up properly, these timelines translate into time-consuming due diligence processes and rounds of negotiation that can lead to delays in a project.
The Right System for Each Individual Need
Facilities have greatly varying needs differing on the types of electricity services, electricity rates, and on how and when they use energy. Therefore, technical assistance on energy modeling, system sizing, energy efficiency analysis, and procurement support is key to ensure that each facility has the right system and best price for its specific needs.
For example, a therapy and rehabilitation center may use power mainly during weekdays while a supermarket may require a steady energy supply 24 hours a day, seven days a week, 365 days a year. In the event of a prolonged power outage, facilities have very different critical load needs — while some facilities may be able to operate with 25 percent of the usual energy supply, others may require 50 percent or more. Time of use and critical load size have significant implications when designing battery size.
There are also physical constraints that affect project design. Some facilities may have a structurally sound roof that has enough space to accommodate the system, while others may not have enough roof space or may need significant repairs to accommodate a solar system. And some facilities may need ground-mounted systems that increase the system costs (ground mounted systems of this size are often more expensive than roof mounted systems based on the additional construction needed).
In most cases, facility owners and or administrators lack the experience and background needed to know if the system is right for their needs, if the price is appropriate given the market, or if the equipment meets the local requirements. With technical assistance, facilities can get the right system at the right price, and are likely to share their positive experiences with colleagues. This will lead to grassroots scaling of renewable energy in communities in Puerto Rico and beyond.
The Importance of Capacity Building
Maintenance is key to the sustainability of these systems. Building the capacity to check the system, use pre-contracted O&M and warranties, replace parts as needed, and ensure continuous safety and system operation is essential. Through a CERI-specific capacity building plan, facility owners and administrators gain the knowledge required to understand the technical aspects, financials, and overall implications of acquiring and maintaining a solar-plus-storage microgrid.
What’s Next for CERI?
The CERI team is preparing a transition to a next phase of demonstration projects across Puerto Rico. This work will set the stage for the full implementation of a scaled-up financing vehicle where hundreds of facilities will benefit from affordable and resilient solar-plus-storage microgrids.
These microgrids will provide stable energy prices, savings from day one, the ability to continue providing essential services in the event of an emergency, environmental benefits, and ultimately, community resilience and wellness. They will enable all community members to receive critical services such as health care, food, water, and communication when needed most.

Tesla has confirmed that it is redesigning its door handles with electronic releases after people were left trapped inside its cars.
Earlier this week, we reported that the NHTSA had opened a new investigation into Tesla over children getting stuck inside cars after electronic door releases fail.
Tesla uses frameless doors with electronic door handles. The button to open the doors first causes the window to lower slightly, allowing the door to open. Then, it electronically unlatches, enabling the door to be swung open.
There’s also a manual latch, but it has been known to be somewhat hard to locate for people who didn’t read the owner’s manual, which is most people.
If there’s an electronic failure, especially after a crash, it can result in occupants having issues exiting the vehicle when they are in a state of panic.
Additionally, if a child is in the vehicle after a failure, it can be challenging for them to locate and use the manual release, which is what the NHTSA is now investigating.
Following the publicization of this long-standing issue this week, Tesla announced that it is redesigning its manual release.
Franz von Holzhausen, Tesla’s chief designer, said in an interview with Bloomberg that the automaker is going to combine the electronic and manual releases into one:
“The idea of combining the electronic one and the manual one together into one button, I think, makes a lot of sense. That’s something that we’re working on.”
The designer said that Tesla is already testing this in China.
It’s not a novel design. Toyota already has the same concept in some of its vehicles. The electronic button to release the door can also be pulled to activate the manual release, which works even if the car has no power.

Hyundai reveals new EVs, hybrids, a midsize pickup, ultra-luxury vehicles, and much more
Get ready to see a lot more Hyundai vehicles on the road. The South Korean auto giant just revealed its most ambitious growth plan ever, packed with advanced new EVs and hybrids across nearly all segments. Hyundai is also launching its first midsize pickup and an extended-range vehicle (EREV) that promises to deliver over 600 miles (960 km) of range.
Hyundai bets on new EVs, hybrids, EREVs, and trucks
During its first CEO Investor Day held outside of Korea, Hyundai unveiled “its most ambitious growth strategy” in company history.
Hyundai is promising to lead the industry’s shift to electrification with a slate of new vehicles set to launch across nearly every powertrain and segment imaginable.
“In an industry facing unprecedented transformation, Hyundai is uniquely positioned to win,” José Muñoz, President and CEO of Hyundai Motor Company, said during the event held in New York on Thursday. Hyundai isn’t simply adapting, “We’re leading it,” Muñoz told attendees.
Hyundai plans to sell 5.55 million vehicles globally by 2030, including 3.3 million “electrified” vehicles, or about 60% of total sales.
With 18 new hybrids, including the first under its luxury Genesis brand, Hyundai expects “significant growth” in North America, Europe, and Korea.
Hyundai said the new vehicles, including EVs and hybrids, will be custom-tailored for buyers in its biggest markets.
Custom-tailored vehicles for the US, Europe, and China
In North America, Hyundai will launch its first midsize pickup by the end of the decade. Hyundai offers the Santa Cruz, which launched in 2021, but the company promises the new model is aimed at “the heart of the US market.”
Those in Europe will see the IONIQ 3, a smaller and more affordable little sibling to the IONIQ 5. It will feature a next-gen infotainment system, Hyundai said, specifically designed for drivers in Europe.
Hyundai announced plans to introduce its first extended range electric vehicle (EREV). Set to arrive in 2027, Hyundai said the new EREV will deliver an “EV-like driving experience with more than 600 miles (960 km) of range” that will use an added gas-powered engine to extend range.
Unlike traditional EREVs, however, Hyundai will use in-house batteries, which it promises will deliver “full EV power performance with less than half the battery capacity.”
In China, Hyundai will take on BYD and other automakers, leading the shift to EVs, with its new Elexio electric SUV. The Elexio SUV is Hyundai’s first locally produced electric vehicle using tech and software from Chinese leaders.
Wait, there’s even more
We will also see seven new high-performance “N” models added to the lineup by 2030. Hyundai aims to sell 100,000 N-branded vehicles by the end of the decade. The new IONIQ 6 N “will introduce a new paradigm for high-performance EVs,” the company said, with advanced new features and tech.
The luxury Genesis brand is celebrating its 10th anniversary with big growth plans over the next few years, including new EREVs, hybrids, and a flagship SUV.
The flagship Genesis electric SUV is expected to launch as the GV90, which we’ve seen out in public testing with ultra-luxury features, including coach doors.
Hyundai announced plans to ramp up production at its Metaplant America (HMGMA) EV plant in Georgia. With a new $2.7 billion investment, the company is creating 3,000 more jobs in Georgia. By 2028, Hyundai plans to build 500,000 hybrid and EV models at the facility annually.
By 2030, Hyundai expects over 80% of vehicles sold in the US will be made domestically. Its supply chain sourcing in the US will also increase from 60% to 80%.
Globally, Hyundai plans to add 1.2 million units to its production capacity by the end of the decade, including in the US, South Korea, and India.

Back in August of 2024, I wrote about buying an electric chainsaw for the first time. It was a Father’s Day present for my dad, who has several acres of property to manage and is reaching the point where even his dad strength isn’t enough to hand saw all day. I wasn’t quite sure what to expect from the current state of electric chainsaws, but I was excited to put the new machine to work. Fast forward a full year, and I’ve got an update: we’ve abused the heck out of it – and it’s still going strong!
Over the past 12 months, this Ego Power+ 18-inch 56-volt electric chainsaw has seen more wood than a mom-and-pop lumber mill. I’ve cut through your standard backyard trees, gnarly old branches, telephone poles, construction lumber, and plenty of 2x4s.
We’ve basically started treating it like a general-purpose tool. If anything is fiber-based and currently of a size that is larger than it should be, the standard response is “go grab the chainsaw…”.
And not just on nice sunny days either – this saw’s been dragged through rain, dust, and mud. And more than once it’s been used in situations that absolutely should have killed it: fully underwater.
At my parents’ place, a good-sized tree had fallen into their lake after the last big storm and needed to be cleared out. We had been putting it off due to the size of the thing, but the water level was rising, and soon it was going to be swamped. One of the most recent times I went over to visit my parents, my dad and I decided it was time to finally tackle the job. Unfortunately, by then the water had risen to the point where the tree trunk was already half-submerged, creating a navigational hazard for all the weird little electric boats I’ve dropped in that lake.
We started by trying to just cut the exposed portion, and I figured we’d then put a long line on the UTV and see if we couldn’t just break the rest of it free. But that’s where my dad’s more hours on the saw than mine played a key role: knowing he could keep pushing it. My dad waded in with the chainsaw and absolutely went to town. He had that thing so deep in the water, cutting through the massive trunk that if it had been a gas-powered chainsaw, it would have literally needed a snorkel to keep running.
And yet, it worked. Not just worked – it powered through. We pulled it out, dried it off, and then it was on to the next job.
The battery life has stayed impressive, the power is still solid, and the chain hasn’t even needed a replacement yet (though I should probably give it a sharpening one of these days). I’ve lost count of how many logs this thing has ripped through, and it’s never let me down.
There is one minor downside worth mentioning: the chain tensioner has gotten a bit stiff. It used to adjust nice and easy, but now it takes a little more effort to tighten. It still works, but you’ve got to put a bit of muscle into it. That’s literally the only wear-and-tear issue I’ve noticed after a full year of borderline tool abuse.
I expected an electric chainsaw to be a convenient, eco-friendly option for light-duty work. What I didn’t expect was a rugged, waterproof (apparently), do-it-all beast that could handle nearly anything I threw at it.
So here’s the one-year verdict: I bought an electric chainsaw, I used it for everything I possibly could (and some things I probably shouldn’t have), and it still works like a champ. If you’re wondering whether an electric chainsaw can hold up over time – this one has more than proven itself.
And if I ever buy a second one, I’ll try to keep it out of the pond. No promises, though.
Author’s note: On reading through this again to proofread, it almost sounds like an ad, but I promise it’s not (those have big “Sponsored” labels on them and I generally steer clear of those). This is just a chainsaw I bought for my dad and we’ve been thrilled with it one year later.
