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.

Following a lawsuit brought against the California Air Resources Board (CARB) by major heavy truck manufacturers over California’s emissions requirements, CARB has struck back with fresh lawsuit of its own alleging that the manufacturers violated the terms of the 2023 Clean Truck Partnership agreement to sell cleaner vehicles.
Daimler Truck North America, International Motors, Paccar and Volvo Group North America sued the California Air Resources Board in federal court this past August, seeking to invalidate the Clean Truck Partnership emissions reduction deal they signed with the state in 2023 to move away from traditional trucks and toward zero-emission vehicles (ZEVs). The main point of the lawsuit was that, because the incoming Trump Administration rolled back Environmental Protection Agency (EPA) policies that had previously given individual states the right to set their own environmental and emissions laws, the truck makers shouldn’t have to honor the deals signed with individual states.
“Plaintiffs are caught in the crossfire: California demands that OEMs follow preempted laws; the United States maintains such laws are illegal and orders OEMs to disregard them,” the lawsuit reads. “Accordingly, Plaintiff OEMs file this lawsuit to clarify their legal obligations under federal and state law and to enjoin California from enforcing standards preempted by federal law.”
After several weeks of waiting for a response, we finally have one: CARB is suing the OEMs right back, claiming that the initial suit proves the signing manufacturers, “(have) unambiguously stated that they do not intend to comply.”
They want to sell Americans more diesel
In its lawsuit, CARB argues that monetary damages alone would not make the people of the State of California whole as far as damages are concerned, citing that the stated goal of the 2023 Clean Truck Partnership was, “to achieve emissions reductions that cannot be measured strictly in financial terms,” according to ACT-News.
The agency is asking the court to compel the truck companies to perform on their 2023 obligations or, failing that, to allow CARB to rescind the contract and recover its costs. A hearing on the truck makers’ request for a preliminary injunction was held Friday, with another court date set for November 21, when CARB will seek to dismiss the case brought forth by the truck brands. The outcome of these cases could shape how state and federal government agencies cooperation on emissions rules in the future.

Starting this month, parking lots in South Korea with more than 80 spaces will be required to install solar canopies and carports. But, unlike similar laws that have been proposed in the US, this new law doesn’t just apply to new construction – existing lots will have to comply as well!
South Korea’s Ministry of Trade, Industry and Energy announced in August that it has prepared an amendment to the Enforcement Decree of the Act on the Promotion of the Development, Use, and Diffusion of New and Renewable Energy to the effect that all publicly- and privately-owned parking lots in the Asian country with room for more than 80 vehicles will be compelled to add solar panels to their lots in a move designed to proactively expand renewable energy and create more solar and construction jobs.
In addition to creating jobs and working to stabilize the local grid with more renewable energy, the proposed solar canopies will offer a number of practical, day-to-day benefits for Korean drivers, as well.
The shaded structures will protect vehicles from heavy rain, snow, and the blistering summer sun — keeping interiors cooler, extending the life of plastics and upholstery, and even helping to preserve battery range in EVs and PHEVs by reducing their AC loads (and, of course, provide charging while the cars are parked).
To their credit, Ministry officials absolutely get it. “Through this mandatory installation,” one unnamed official told Asia Business Daily, “we expect to expand the distribution of eco-friendly renewable energy generation facilities while providing tangible benefits to the public. By utilizing idle land such as parking lots, we can maximize land use efficiency. In addition, installing canopy-type solar panels can provide shade underneath, offering noticeable comfort to people using parking lots during hot weather.”
The new rule was approved in late September, and is expected to go into effect later this month, with new installation projects set to begin immediately.
It could work here
South Korea is proving that an idea like is practical. Here in the US, we’re proving that out, too – the Northwest Fire District in Arizona partnered with Standard Solar to build a conceptually similar, 657 kW solar carport system across 12 parking lots (shown, above) that delivers more than 1.23 million kWh of clean, emissions-free power annually and offsets the equivalent of 185,000 vehicles’ worth of harmful carbon emissions.
That’s just Arizona. In New York, a new initiative to help expand solar into parking lots has more than doubled commercially zoned land where EV charging stations can be sited, “freeing up” an additional 400 million square feet of space throughout the city.
Sun-rich states like Texas, New Mexico, and Florida could also benefit, and even if we’re “just” adding fresh energy sources to municipal parking, dealer lots, and public schools, we could do a lot to reduce the cost of energy generation for the entire community. And, for what it’s worth, that seems to be right in line with the big reasons why people are choosing to add solar to their homes today.
What do you guys think – would something like this work in the US, or are we too far gone down the sophomoric, pseudo-libertarian rabbit hole to ever dig our way out? Let us know your take in the comments.

Autonomous taxi company Waymo faced scrutiny last month when a car was caught on video illegally passing a stopped school bus that was letting children off in Atlanta. Now, the National Highway Traffic Safety Administration (NHTSA) is looking into it.
Georgia State Representative Clint Crowe seemed stunned after being presented with video of a Waymo driverless car illegally passing a stopped school bus on Briarcliff Road in Atlanta last month. “I’m a big fan of new technologies and emerging technologies and I think that driverless cars are going to become more prevalent,” he told local NBC news affiliate WBIR. “But we got [sic] to think about how they’re going to comply with the law.”
WBIR | Waymo illegally passes school bus
Crowe co-sponsored Addy’s Law in 2024. The legislation was named after 8-year-old Addy Pierce, who was killed in Henry County after being struck while crossing the street to get to her bus. The law stiffened penalties for illegally passing a stopped school bus, carrying penalties of up to $1,000 in fines and even jail time.
According to Crowe, those rules still apply to autonomous vehicles. “The majority of our traffic laws, the penalty is usually a fine and or driver’s license suspension. These cars don’t have a driver, so they don’t have a driver’s license and so we’re really going to have to rethink who’s the responsible party, who’s going to be responsible for being in control of that vehicle and who’s going to be the operator of that vehicle,” he said.
Crowe believes manufacturers should face stronger consequences when their vehicles break the law, saying the $1,000 fine doesn’t go far enough.
Now, thanks to pressure from social media and politicians like Crowe and Geoirgia State Senator Rick Williams, who helped co-author Addy’s Law, it seems like NHTSA is getting involved.
Prompted by media reports, the US Department of Transportation issued an investigation regarding Waymo’s AV, which states that, “the AV initially stopped, but then drove around the front of the bus by briefly turning right to avoid running into the bus’s right front end, then turning left to pass in front of the bus, and then turning further left and driving down the roadway past the entire left side of the bus. During this maneuver, the Waymo AV passed the bus’s extended crossing control arm near disembarking students (on the bus’s right side) and passed the extended stop arm on the bus’s left side.”
While it remains to be seen how much work NHTSA is actually doing amid the ongoing shutdown of the Federal government, it’s worth noting that, regardless of the outcome, Senator Williams said he plans to introduce new legislation that would hold driverless car companies accountable with higher fines if their vehicles violate traffic laws. If that passes in Georgia, it could set the stage for politicians across the US and even abroad to use similar fins to halt the spread of autonomous taxis in their states.
“Driverless cars should be stopped until it can be figured out,” said Williams. “We should not have this on the road. It’s too dangerous for our children.”
You can read NHTSA summary, below.
We’re typically pretty tech- and autonomous-forward here, but as a parent I would absolutely lose my s*** if a Waymo or Robotaxi or whatever else ran over my kid. but I’ve also seen plenty of human drivers blow past a school bus with a knee on the steering wheel and both eyes glued firmly to their phones. Let us know who you’d be more ready to trust with your kids’ lives in the comments.
