IRENA Study Finds Renewables Are Becoming Popular In Large Cities
The International Renewable Energy Agency (IRENA) released a study on renewable energy policies for cities last month. The reason for the focus on cities is due to their ability to scale up renewables and meet emission-reduction targets. Large cities have the revenue bases, regulatory frameworks, and infrastructure to support this while smaller ones usually don’t.
The study pointed out that it’s mostly cities that are raising awareness and moving towards energy transitions. Smaller and even medium-sized cities that have 1 million or fewer inhabitants usually don’t have the funding or political support to embrace renewables, and they are also not as highly visible as megacities.
The study analyzed six medium-sized cities from China, Uganda, and Costa Rica. They were chosen due to two reasons:
- They have effective policies in place, or
- They have untapped renewable energy sources that could launch their sustainable development.
A Quick Look At The Study
The study takes a dive into the challenges and successes that are seen in the deployment of renewable energy in medium-sized cities and provides case studies of the six cities studied. A quick look at the executive summary shows that these cities have a population range from 30,000 to 1 million inhabitants.

Altogether, cities are responsible for around 70% of global energy-related greenhouse gas emissions. Urban areas have high rates of air pollution as well, with 98% of cities with over 100,000 inhabitants in low- and middle-income countries failing to meet the World Health Organization’s (WHO’s) air quality guidelines.
Renewable energy technologies (RETs) play a central role in easing the severity of climate change while providing cleaner air. Research is often focused on the urban trends of particular sets of global megacities and doesn’t really focus any attention on cities with 1 million or fewer inhabitants, which is the fastest growing category and home to some 2.4 billion people (59% of the world’s total urban population).
Cities are motivated to promote renewables by several factors, such as:
- Economic development and jobs.
- Social equity.
- Governance.
- Air quality.
- Secure and affordable energy.
- Such as access to clean energy.
- Climate stability.
- Energy-related policymaking requires a lot of flexibility — it involves governance structures and processes as well as the diverse motivations of many stakeholders.

Cities’ plans need to be tailored to their own circumstances, and some factors shaping city energy profiles include:
- Demographic trends.
- Climate zone.
- Ownership of energy assets.
- Settlement density.
- Regulatory authority.
- Institutional capacity.
- Economic structure and wealth.

Case Studies 1 & 2: Chongli District and Tongli Town
The two cities in this section are Chongli District and Tongli Town. In the cases of these two Chinese cities, the study found that both benefit from the availability of large-scale renewable energy projects, with wind and solar being the best options. It has a level of existing deployment which provides a solid base for the cities’ ambitious targets compared to other cities where renewables aren’t as present.
The Chinese cities benefit from the availability of financial resources that target renewable energy deployment. Tongli Town receives support from its upper-level administration, which has one of the largest revenue streams among Chinese city governments.
Tongli Town is one of the most replicable in developed cities that resemble Suzhou. Although Zhangjiakou City isn’t as wealthy as Suzhou, the Chongli District was able to receive financial support from the national government as a result of the Winter Olympics.
Its example shows that distributed renewables could also play a large role in cities. PV generation systems could be deployed outside of highly populated city centers, for example. Tongli Town also benefits from the relationship between local governments and local manufacturing industries that deploy RETs.
Showcase events such as the Winter Olympics also help a city gain visibility — this is what happened with the Chongli District. It and the Zhangjiakou Municipality linked the development targets of local renewables with the hosting arrangements of the Winter Olympics. This focused political attention and financial support on renewable energy projects.
Cross-governmental collaboration and existing manufacturing industries benefitting from renewable deployment also played key roles.
Case Studies 3 & 4: Kasese and Lugazi
This case study focused on the Ugandan cities of Kasese and Lugazi. Uganda has a variety of energy resources that includes hydropower, biomass, solar, geothermal, peat, and fossil fuels. Yet only 20% of the population has access to electricity. The World Bank estimated in 2017 that only 2% of the nation’s population has access to clean cooking fuels and technologies.
In Uganda, renewable energy deployment benefits the local communities in many ways while boosting socio-economic goals. In both Lugazi and Kasese, solar street lighting and solar home systems (SHSs) massively saved both municipalities and households while extending business hours for street sellers. It’s also improved public safety and telecommunications, which led to the creation of job opportunities.
Ugandan cities face obstacles to greater local deployment. Institutional constraints, such as narrow political mandates and tight municipal finances, present huge obstacles to effective policy action. Scaling up projects will need greater funding as well as capacity building. This requires a national enabling framework that supports the local government at the district and municipal levels. Kasese and Lugazi have benefited from initiatives targeting sustainable energy at the district level.
Financial resources for both district and municipal governments are needed. Renewables may offer savings in the long run, but the upfront costs usually surpass the funds available to Uganda’s municipalities and districts. For now, initiatives such as solar street lighting are usually linked to third-party financing support. An example of this is the World Bank’s Uganda Support to Municipal Infrastructure Development Programme.
Case Studies 5 & 6: Cartago and Grecia, and Guanacaste
Costa Rica has a population of around 5 million people and is the smallest of the three countries that were studied in the report. Some key questions discussed in the country include what role is played by the public and private sectors and what degree to which electricity generation should be based on centralized and decentralized sources. Some of the key issues and challenges that shape the nation’s efforts to promote the use of renewable energy include:
- Mandates.
- Strengthening cities’ ability to act with a diverse set of actors.
- Transport as the next frontier.
For cities without the mandate, their scopes of action are limited and this is one of the main obstacles to a sustainable urban future. In the case of Cartago and Grecia, the cities have taken active measures to promote green policies in the transport and tourism sectors. Costa Rica’s “capital of renewable energy,” Guanacaste, has hosted several projects in the fields of wind, solar, and geothermal energy.
Another key lesson from the study in the case of Costa Rica is that when the share of renewables in the electricity mix is already high, transport becomes the next frontier. Compared to Columbia, Panama, and Chile, Costa Rica has a lack of municipal transport. The other countries are advancing with electric buses and other electric-mobility projects and these contrast with Costa Rica.

Newly published data from the Federal Energy Regulatory Commission (FERC), reviewed by the SUN DAY Campaign, reveal that solar accounted for over 75% of US electrical generating capacity added in the first nine months of 2025. In September alone, solar provided 98% of new capacity, marking 25 consecutive months in which solar has led among all energy sources.
Year-to-date (YTD), solar and wind have each added more new capacity than natural gas has. The mix of all renewables remains on track to exceed 40% of installed capacity within three years; solar alone may be 20%.
Solar was 75% of new generating capacity YTD
In its latest monthly “Energy Infrastructure Update” report (with data through September 30, 2025), FERC says 48 “units” of solar totaling 2,014 megawatts (MW) were placed into service in September, accounting for 98% of all new generating capacity added during the month. Oil provided the balance (40 MW).
The 567 units of utility-scale (>1 MW) solar added during the first nine months of 2025 total 21,257 MW and were 75.3% of the total new capacity placed into service by all sources. Solar capacity added YTD is 6.5% more than that added during the same period a year earlier.
Solar has now been the largest source of new generating capacity added each month for 25 consecutive months, from September 2023 to September 2025. During that period, total utility-scale solar capacity grew from 91.82 gigawatts (GW) to 158.43 GW. No other energy source added anything close to that amount of new capacity. Wind, for example, expanded by 11.07 GW while natural gas’s net increase was just 4.60 GW.
Between January and September, new wind energy has provided 3,724 MW of capacity additions – an increase of 28.6% compared to the same period last year and more than the new capacity provided by natural gas (3,161 MW). Wind accounted for 13.2% of all new capacity added during the first nine months of 2025.
Renewables were 88% of new capacity added YTD
Wind and solar (plus 4 MW of hydropower and 6 MW of biomass) accounted for 88.5% of all new generating capacity while natural gas added just 11.2% YTD. The balance of net capacity additions came from oil (63 MW) and waste heat (17 MW).
Utility-scale solar’s share of total installed capacity (11.78%) is now virtually tied with that of wind (11.80%). If recent growth rates continue, utility-scale solar capacity should surpass that of wind in FERC’s next “Energy Infrastructure Update” report.
Taken together, wind and solar make up 23.58% of the US’s total available installed utility-scale generating capacity.
Moreover, more than 25% of US solar capacity is in the form of small-scale (e.g., rooftop) systems that are not reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar and wind to more than a quarter of the US total.
With the inclusion of hydropower (7.59%), biomass (1.05%) and geothermal (0.31%), renewables currently claim a 32.53% share of total US utility-scale generating capacity. If small-scale solar capacity is included, renewables now account for more than one-third of the total US generating capacity.
Solar soon to be No. 2 source of US generating capacity
FERC reports that net “high probability” net additions of solar between October 2025 and September 2028 total 90,614 MW – an amount almost four times the forecast net “high probability” additions for wind (23,093 MW), the second fastest growing resource.
FERC also foresees net growth for hydropower (566 MW) and geothermal (92 MW) but a decrease of 126 MW in biomass capacity.
Meanwhile, natural gas capacity is projected to expand by 6,667 MW, while nuclear power is expected to add just 335 MW. In contrast, coal and oil are projected to contract by 24,011 MW and 1,587 MW, respectively.
Taken together, the net new “high probability” net utility-scale capacity additions by all renewable energy sources over the next three years – the Trump administration’s remaining time in office – would total 114,239 MW. On the other hand, the installed capacity of fossil fuels and nuclear power combined would shrink by 18,596 MW.
Should FERC’s three-year forecast materialize, by mid-fall 2028, utility-scale solar would account for 17.3% of installed U.S. generating capacity, more than any other source besides natural gas (39.9%). Further, the capacity of the mix of all utility-scale renewable energy sources would exceed 38%. The inclusion of small-scale solar, assuming it retains its 25% share of all solar energy, could push solar’s share to over 20% and that of all renewables to over 41%, while the share of natural gas would drop to less than 38%.
In fact, the numbers for renewables could be significantly higher.
FERC notes that “all additions” (net) for utility-scale solar over the next three years could be as high as 232,487 MW, while those for wind could total 65,658 MW. Hydro’s net additions could reach 9,927 MW while geothermal and biomass could increase by 202 MW and 32 MW, respectively. Such growth by renewable sources would swamp that of natural gas (29,859 MW).
“In an effort to deny reality, the Trump Administration has just announced a renaming of the National Renewable Energy Laboratory (NREL) in which it has removed the word ‘renewable’,” noted the SUN DAY Campaign’s executive director Ken Bossong. “However, FERC’s latest data show that no amount of rhetorical manipulation can change the fact that solar, wind, and other renewables continue on the path to eventual domination of the energy market.”

The Century is considered the most luxurious Toyota, and now it’s being spun off into its own high-end brand. Despite the rumors, the ultra-luxury brand won’t be as electric as expected.
Toyota sets new luxury brand up to fail with ICE plans
First introduced in 1967, the Century was launched in celebration of Toyota’s founder, Sakichi Toyoda’s 100th birthday.
The Century has since become a symbol of status and wealth in Japan, often used as a chauffeur car by high-profile company officials.
Toyota previewed the future of the ultra-luxury marquee at the 2025 Japan Mobility Show in October, launching it as a new standalone brand positioned above Lexus.
The new Century brand is set to rival higher-end automakers like Rolls-Royce and Bentley, but it won’t be as electric as initially expected. Toyota’s powertrain boss, Takashi Uehara, told CarExpert that the luxury brand’s first vehicle will, in fact, have an internal combustion engine.
Although no other details were offered, Uehara confirmed, “Yes, it will have an engine.” As to what kind, that has yet to be decided, Toyota’s powertrain president explained.
Like the next-gen Lexus supercar and upcoming Toyota GR GT, Uehara said the Century model could include a V8 engine.
The Century has been Toyota’s only vehicle with a V12 engine. In 2018, Toyota dropped the V12 in favor of a V8 hybrid powertrain for its third-generation.
Toyota’s Century launched its first SUV in 2023, currently on sale in Japan with a V6 plug-in hybrid system alongside the sedan.
Already widely considered the biggest laggard in the shift to fully electric vehicles, Toyota doubled down, developing a series of new internal combustion engines for upcoming models.
Century is one of the five global brands the Japanese auto giant introduced in October, along with Daihatsu, GR Sport, Lexus, and Toyota.
Electrek’s Take
It’s not surprising to see Toyota sticking with ICE for its ultra-luxury Century brand, but it will likely be a costly move.
Chinese auto giants, such as BYD and FAW Group, are quickly expanding into new segments, including high-end models under luxury brands such as Yangwang and Hongqi.
These companies are now expanding into new overseas markets, like Europe and Southeast Asia, where Japanese brands like Toyota have traditionally dominated, to drive growth.
Top luxury brands, including Porsche, BMW, and Mercedes-Benz, are already struggling to keep pace with Chinese EV brands. How does Toyota plan to compete with an “ultra-luxury” brand that still sells outdated ICE vehicles? We will find out more over the coming months and years as new sales data is released.

SparkCharge has partnered with the Massachusetts Clean Energy Center (MassCEC) and Zipcar to launch the Northeast’s first off‑grid, mobile DC fast‑charging hub for shared EVs. The goal is to bring fast, reliable EV charging infrastructure into communities without having to wait for costly or slow grid upgrades.
The hub sits at Zipcar’s maintenance facility in East Boston, an Environmental Justice community. It’s funded through MassCEC’s InnovateMass program and gives onsite mechanics the ability to quickly recharge a rotating fleet of Zipcar EVs before they’re dispatched across Greater Boston. Members and rideshare drivers who rent Zipcars will get steadier access to charged EVs.
“Electrification should never be limited by where the grid is or how long it takes,” SparkCharge founder and CEO Joshua Aviv said. “With this program in East Boston, we’re showing how fleets can deploy at scale, in any community, and deliver clean mobility today.”
At the center of the setup is SparkCharge’s Mobile Battery‑Powered Trailer, which delivers 320 kW of DC fast charging without the delays and big price tags that usually come with fixed infrastructure. The trailer can recharge from Zipcar’s existing onsite power between sessions, topping up its high‑capacity batteries without stressing the local grid. Since it avoids major grid upgrades entirely, the model is designed to deploy quickly and at zero upfront cost for fleets.
MassCEC says the project shows what community‑first fast charging can look like. “Every resident deserves access to clean, reliable transportation,” said Leslie Nash, MassCEC’s senior director of Technology‑to‑Market. “By partnering with SparkCharge and Zipcar in East Boston, we’re showing how Massachusetts is leading the way in clean transportation innovation.”
The hub also plays into Massachusetts’ push to hit its net‑zero 2050 targets. As shared mobility grows, electrifying fleets will be key to cutting emissions in dense urban corridors. This project introduces a scalable charging option to a part of Boston that is underserved by public charging, helping to keep Zipcar’s EVs reliably on the road.
“For twenty‑five years, Zipcar has been a leader in shared mobility, and we’re proud to take another step toward a more sustainable future,” said Angelo Adams, Zipcar’s president. “Working with SparkCharge and MassCEC allows us to bring fast, reliable EV charging directly to our members and rideshare drivers.”
Zipcar, which is owned by car rental company Avis Budget, announced on December 1 that it was shutting down its UK operations by December 31, 2025. An Avis Budget spokesperson stated that the reason was “to streamline operations, improve returns, and position the company for long-term sustainability and growth,” adding that “all other markets remain unaffected.”
