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.
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.

Iron phosphate (LFP) batteries, which don’t use nickel or cobalt, are traditionally cheaper and safer, but they offer less energy density, which means less efficiency and a shorter range for electric vehicles.
However, they have improved enough recently that it now makes sense to use cobalt-free batteries in lower-end and shorter-range vehicles. It also frees up the production of battery cells with other, more energy-dense chemistries to produce longer-range vehicles.
The main issue is that LFP battery cell production is currently almost entirely concentrated in China. Therefore, it creates a logistical problem for electric vehicles produced in other markets.
Furthermore, in the US, it creates a problem for automakers trying to take advantage of the new federal tax credit for electric vehicles, which requires that the batteries of electric vehicles be produced in North America in order for buyers to get the full $7,500 credit. It creates a demand to bring LFP production to North America.
Now Tesla is rumored to be doing the same thing. Bloomberg first reported the rumor:
The EV maker discussed plans involving Contemporary Amperex Technology Co. Ltd. with the White House in recent days, said the people, who asked not to be identified revealing private conversations. Tesla representatives sought clarity on the Inflation Reduction Act rules that the Biden administration is finalizing this week, according to some of the people. Rohan Patel, the company’s senior global director of public policy, was among those involved with the discussions, one of the people said.
The report is light on detail, but it states that Tesla is looking at a similar structure to Ford’s own deal with CATL. Texas has also been rumored to be a possible location for the new factory.
The LFP cells would enable Tesla buyers to get the full tax on the base Model 3, which is about to lose the incentive because its cells currently come from CATL’s Chinese factories.

Swedish electric airplane maker Heart Aerospace is joining forces with BAE Systems to develop a battery system for its ES-30 electric plane.
Heart partners with BAE to develop electric plane battery
Heart Aerospace is paving the way for sustainable electric air travel to become the norm with its leading-edge zero-emission aircraft.
We first covered the company in 2021 after it made waves with its ES-19 electric airplane. The aircraft was designed to carry up to 19 people up to 250 miles (400 km), perfect for short-distance travel.
The innovation was enough to attract an investment from the third largest US air carrier, United Airlines, in July 2021. United committed to purchasing and deploying 100 ES-19 electric aircraft to its fleet as it works to erase emissions from its fleet “without relying on traditional carbon offsets.”
Air Canada, the largest airliner in Canada, invested $5 million into Heart last year in addition to ordering 30 of its newest model, the ES-30.
Heart introduced the ES-30 last year, an electric plane driven by four electric motors and a battery system. The electric aircraft will have a fully-electric zero-emission range of up to 200 km (124 miles) and 30-minute fast charge capabilities. Hybrid reserve turbogenerators allow travel of nearly 500 miles (800 km) at 25 people max.

To advance the ES-30 battery system, Heart is partnering with BAE Systems, best known for its leading defense and aerospace solutions. The battery system will be the “first of its kind” for a conventional takeoff and landing regional aircraft, operating with zero emissions and significantly reduced noise.
The collaboration will utilize BAE Systems’ over 25 years of experience electrifying heavy-duty industrial vehicles. Chief operating officer at Heart Aerospace, Sofia Graflund, said:
BAE Systems’ extensive experience in developing batteries for heavy-duty ground applications, and their experience in developing safety critical control systems for aerospace, make them an ideal partner in this important next step for the ES-30 and for the aviation industry.
Heart Aerospace says it already has 230 orders and another 100 options for the ES-30 electric aircraft. In addition, Heart says it has a letter of intent for another 108 planes. The ES-30 is scheduled to enter service in 2028.
Heart Aerospace is aiming to double the all-electric range of its aircraft by the late 2030s with close to 250 miles (400km) range. In addition to offering zero emissions, electric airplanes feature lower costs (electricity compared to jet fuel) and less maintenance due to engine repair.
Electrek’s Take
Although 124 miles may not seem like much, it will be perfect for regional air travel while building a base for the future of zero-emission air travel.
The 30-minute fast charge feature is perfect for turning around flights quickly in between loading passengers and luggage.
