Microgrids are all the rage, and they have been for a few years. Who doesn’t like the idea of a little self-sustainable, independent grid that ropes in solar power, wind power, battery energy storage, EV charging stations and perhaps a tad of some other less common electricity solutions? It sounds simple: tie them all together and make sure they’re working intelligently to constantly supply energy to the people and businesses who need it.
Of course, when it comes to turning an idea into action, things can get a lot more complicated than they look on the surface. Microgrids are often more complicated and challenging to implement than they look on paper. Also, if someone builds such a system, it is evident they’d like to get their money back on it and then make a profit. Trying to forecast whether that will happen and how to make it happen is even more complicated.
Michael Stadler and Adib Naslé published an article in the academic journal The Electricity Journal a couple of years ago, “Planning and Implementation of Bankable Microgrids,” laying out the “multiple, complex steps and software tools” that were available for implementing and evaluating microgrid projects at the time. A key conclusion: “Existing techniques treat every Microgrid project as a unique system, resulting in expensive, non-standardized approaches and implementations which cannot be reliably compared. That is, it is not possible to correlate the results from different planning methods performed by different project developers and/or engineering companies.” The industry has been lacking uniform approaches and evaluation systems to plan and optimize microgrid systems efficiently and at scale.
Furthermore, the planning and evaluation systems in place were not set up to be easily understandable and usable by different key players in developing, investing in, financing, or approving microgrids. The authors write, “For this sophisticated engineering task, tools and models are needed that can include GridLAB-D (GridLab-D, 2017) […] or OpenDSS, designed by the Electric Power Research Institute (EPRI, 1997–2018). Some of these analyses introduce considerable complexities and need an engineering background, limiting the usability for certain stakeholders such as bankers, investors, or real estate companies. Furthermore, most of the time, the technical design process (cable and transformer sizing) is completely decoupled from the conceptual design (selecting and placing technologies), and no integration exists, obstructing any data flow. This is especially problematic when the technical design reveals issues with the underlying conceptual design, leading to unplanned engineering time and costs.”
What is their solution? A unified software system with integrated design stages and a user-friendly experience that allows anyone from bankers to engineers to plan, visualize, and optimize a project. And that’s what these guys are now offering through XENDEE — “one single platform, allowing multiple views, complexity levels, and details depending on the user class, i.e., engineer versus financier versus construction consultants.” In fact, XENDEE’s software platform recently won the prestigious 2021 Edison Gold Award in Human Critical Infrastructure. Here’s a video overview, but I’ll cover some of the core company highlights below if you’re not keen on watching the full rundown:
XENDEE describes their platform as a “streamlined interface” that “removes traditional technical barriers and enables new users from business, sales, financial and engineering backgrounds to accurately screen Microgrid investment opportunities in minutes.” This speed and efficiency in validating projects can also be a big deal for companies and government organizations looking to scale microgrid projects faster and further.

An important element — perhaps the key element — here is that funding institutions and engineers/developers can use the XENDEE platform together to optimize both technical and financial goals. “Additionally, our physically-based economic decision support system couples financial optimization with detailed electrical power system analysis to verify resilience and financial viability before the first cable is laid.”

You don’t have the technicians looking at one thing, the finance people looking at something else, and a person or team in the middle trying to understand both and translate as needed. Using an old cliche, you don’t end up trying to stuff a square block into a circular hole — and ending up with hair on the floor from frustration and failure.
“XENDEE’s immersive user experience and generative design optimization technology considers millions of possibilities and autonomously creates the optimal Microgrid system, investment thesis, and control strategy that best meets your customer’s envisioned benefits and goals in minutes.”
Naturally, this is marketing talk and pretty pictures of an attractive software platform. The proof is in the pudding. Does this work as eloquently explained? Well, you can’t confirm that without trying it out, and we’d recommend scheduling a product demonstration with a member of the XENDEE team using this link. If your mouth is starting to water and you’re in this industry, note that XENDEE highlights and summarizes four key stages where its software can be used to optimize time efficiency and cost efficiency: 1) Client Feasibility Study, 2) Custom Tailored Bankability Study, 3) Balance of System Engineering Analysis, 4) Implementation Management.

One of the greatest things we can do worldwide to facilitate the use of clean energy and reduce carbon emissions is to more quickly and efficiently roll out distributed energy microgrid solutions. I hope to see XENDEE’s platform get into the hands of many more developers, engineers, government officials, and financiers in order to help achieve that. I have not seen a comparably compelling platform in my years of covering this sector — with the caveat being that I also haven’t personally developed or financed a microgrid project, so can only provide this top-level view of this solution and the microgrid world as a whole.
GM may have decided to pull the plug on the forward-looking Chevy Brightdrop electric van a few months ago, but don’t let that stop you, but don’t let that fool you. Right now might be the best time ever to get your hands on one.
Despite that, I’ve heard more than one fleet manager express hesitation at the thought of adding a discontinued product to their fleet, even if it is a killer discount. To them, I offer the following, model-agnostic rebuttal:

Legacy brands support their products

Companies like GM aren’t going anywhere soon, and neither are the customers they’ve spent millions of dollars acquiring over the past several decades. They’ll keep building parts and offering service and maintenance on vehicles like the Brightdrop for at least a decade — not least of which because they have to!
GM sells each Brightdrop with a minimum 8 year/100,000 mile warranty on the battery and other key components, which can be extended either through GM itself or through reputable third-party companies like Xcelerate Auto for seven more.
So, yes: parts longevity and manufacturer support will be there (something I’d be less confident about with a startup like Rivian or Bollinger, for example), but there’s more.
Section 179 and local incentives

The One Big, Beautiful Bill Act (OBBBA) of 2025 gutted America’s energy independence goals and ensuring its auto industry would fall even further behind the Chinese in the EV race, but the loss of Section 45W wasn’t the only change written into the IRS’ rulebook. Section 179, an immediate expense reduction that business owners can take on depreciable equipment assets, has been made significantly more powerful for 2025.
The section 179 expense deduction is limited to such items as cars, office equipment, business machinery, and computers. This speedy deduction can provide substantial tax relief for business owners who are purchasing startup equipment.
The revised Section 179 tax credit (or, more accurately, expense reduction) allows for a 100% deduction for equipment purchases has doubled to $2.5 million, with a phase-out kicking in at $4 million of capital investments that drops to zero at $6.5 million. That credit and can be applied to new and used vehicles, as well as charging infrastructure, battery energy storage systems, specialized tools, and more (as long as they’re new to you).
All of which is to say: don’t let a little thing like GM discontinuing the Brightdrop convince you to skip it. If you do that, the bean counters that killed off the Buick Grand National, GMC Syclone, and Pontiac Fiero win.

US Energy Information Administration (EIA) data released on November 25 and reviewed by the SUN DAY Campaign reveal that, during the first nine months of 2025 and for the past year, solar and battery storage have dominated growth among competing energy sources, while fossil fuels and nuclear power have stagnated.
Solar set new records in September
EIA’s latest “Electric Power Monthly” report (with data through September 30, 2025), once again confirms that solar is the fastest-growing source of electricity in the US.
In September alone, electrical generation by utility-scale solar (>1 megawatt (MW)) ballooned by well over 36.1% compared to September 2024, while “estimated” small-scale (e.g., rooftop) solar PV increased by 12.7%. Combined, they grew by 29.9% and provided 9.7% of US electrical output during the month, up from 7.6% a year ago.
Moreover, generation from utility-scale solar thermal and photovoltaic systems expanded by 35.8%, while that from small-scale systems rose by 11.2% during the first nine months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 29.0% and produced a bit over 9.0% (utility-scale: 6.85%; small-scale: 2.16%) of total US electrical generation for January-September, up from 7.2% a year earlier.

And for the third consecutive month, utility-scale solar generated more electricity than US wind farms: by 4% in July, 15% in August, and 9% in September. Including small-scale systems, solar has outproduced wind for five consecutive months and by over 40% in September.
Wind leads among renewables
Wind turbines across the US produced 9.8% of US electricity in the first nine months of 2025 – an increase of 1.3% compared to the same period a year earlier and 79% more than that produced by US hydropower plants.
During the first nine months of 2025, electrical generation from wind plus utility-scale and small-scale solar provided 18.8% of the US total, up from 17.1% during the first three quarters of 2024.
Wind and solar combined provided 15.1% more electricity than did coal during the first nine months of this year, and 9.8% more than the US’s nuclear power plants. In fact, as solar and wind expanded, nuclear-generated electricity dropped by 0.1%.
Renewables are now only second to natural gas
The mix of all renewables (wind, solar, hydropower, biomass, and geothermal) produced 8.7% more electricity in January-September than they did a year ago, providing 25.6% of total US electricity production compared to 24.2% 12 months earlier.
Renewables’ share of electrical generation is now second to only that of natural gas, which saw a 3.8% drop in electrical output during the first nine months of 2025.
Solar + storage have dominated 2025
Between October 1, 2024, and September 30, 2025, utility-scale solar capacity grew by 31,619.5 MW, while an additional 5,923.5 MW was provided by small-scale solar. EIA foresees continued strong solar growth, with an additional 35,210.9 MW of utility–scale solar capacity being added in the next 12 months.
Strong growth was also experienced by battery storage, which grew by 59.4% during the past year, adding 13,808.9 MW of new capacity. EIA also notes that planned battery capacity additions over the next year total 22,052.9 MW.
Wind also made a strong showing during the past 12 months, adding 4,843.2 MW, while planned capacity additions over the next year total 9,630.0 MW (onshore) plus 800.0 MW (offshore).
On the other hand, natural gas capacity increased by only 3,417.1 MW and nuclear power added 46.0 MW. Meanwhile, coal capacity plummeted by 3,926.1 MW and petroleum-based capacity fell by an additional 606.6 MW.
Thus, during the past year, renewable energy capacity, including battery storage, small-scale solar, hydropower, geothermal, and biomass, ballooned by 56,019.7 MW while that of all fossil fuels and nuclear power combined actually declined by 1,095.2 MW.
The EIA expects this trend to continue and accelerate over the next 12 months. Utility-scale renewables plus battery storage are projected to increase by 67,806.1 MW (a forecast for small-scale solar is not provided). Meanwhile, natural gas capacity is expected to increase by only 3,835.8 MW, while coal capacity is projected to decrease by 5,857.0 MW, and oil capacity is anticipated to decrease by 5.8 MW. EIA does not project any new growth for nuclear power in the coming year.
SUN DAY Campaign’s executive director Ken Bossong said:
The Trump Administration’s efforts to jump-start nuclear power and fossil fuels are not succeeding. Capacity additions from solar, wind, and battery storage continue to dramatically outpace those from gas, coal, and nuclear, and by growing margins.

The bZ3X is off to a strong start as Toyota’s most affordable electric SUV, starting at around $15,000 in China.
The bZ3X is a $15,000 Toyota electric SUV in China
Toyota’s joint venture, GAC Toyota, launched the bZ3X in China this March, an affordable, compact electric SUV aimed at young families.
The bZ3X is Toyota’s “first 100,000 yuan-level pure electric SUV,” starting at just 109,800 yuan, or roughly $15,000.
By May, the electric SUV was the best-selling foreign-owned EV in China, beating out the Volkswagen ID.3, Nissan N7, BMW i3, and Volkswagen ID.4 CROZZ.

According to the latest update, the bZ3X remains a hot seller. GAC Toyota announced that bZ3X sales exceeded 10,000 units for two consecutive months, with 10,010 units sold in November. Cumulative deliveries have now surpassed 62,000 units.
GAC Toyota recently put the electric SUV through rigorous testing on a winter road trip across China, “showcasing its impressive capabilities as a 100,000-yuan-class pure electric vehicle.”
Measuring 4,645 mm in length, 1,885 mm in width, and 1,625 mm in height, the bZ3X is about the same size as BYD’s popular Yuan Plus (sold as the Atto 3 overseas).
Inside, the electric SUV is a major upgrade over the Toyota vehicles we’re accustomed to, with advanced ADAS features, smart storage, and large digital screens.
The bZ3X is available in seven different trims in China, two of which include a LiDAR. Upgrading to the LiDAR version costs 149,800 yuan ($20,500).
Toyota’s electric SUV is available with 50.04 kWh and 67.92 kWh battery pack options, providing a CLTC range of 430 km (267 miles) and 610 km (379 miles), respectively.
Less than two weeks ago, GAC Toyota launched pre-sales for the bZ7, a new flagship electric sedan. According to Toyota, the new flagship EV “possesses a higher level of intelligence than any of Toyota’s offerings in global markets,” as the automaker fights to regain market share in China’s fierce auto market.
