Generating over 80% of global GDP, cities have always been the engines of economic growth and innovation. As the world becomes increasingly urbanized, they are also at the forefront of some of the biggest challenges we face today. From climate change and population growth to aging infrastructure and resource depletion, our natural and built environments are being tested to their limits. Urban energy systems can play a critical role in supporting resilience and prosperity, enabling cities using renewable energy to adapt to changing circumstances and thrive in the face of uncertainty.
Urgent action is needed on all fronts to ensure cities of the future continue to meet the needs of their communities, considering affordability, livability, and inclusivity. Clean and renewable energy sources, and the development of smarter and sustainable urban energy systems, can help meet the growing energy demand. But with cities contributing to 75% of global carbon emissions, are there significant enough steps we can take before it’s too late?
The biggest challenge in cities is to become independent, making the systems more local. For example, mobility hubs combined with energy hubs. Every city is different, so there is no one solution.
Navigating energy challenges in a rapidly changing world
The 2022 energy crisis highlighted the impact on European citizens, most notably record-high energy costs. In the US, nearly half of homeowners are concerned about power outages stemming from weather events and cyberattacks on the power grid.
And in the UK, around 13% of households are ‘fuel poor’, meaning increased energy costs would push them into poverty if used at adequate levels.
Energy transition challenges are both complex and multifaceted, and they impact everyone. They also pose the greatest opportunities to change the course of our collective futures.
Climate change and decarbonization
With climate change already causing rising sea levels, extreme weather patterns, and other destructive phenomena, cities are under pressure to take action, setting ambitious targets to reduce their carbon footprint. Energy transition is key to achieving these targets, with many cities already shifting to lower-carbon or renewable energy sources like solar, wind, and hydropower. In Amsterdam, Arcadis has worked with the municipality to develop an Energy Transition Strategy that aims to achieve a carbon-neutral city by 2040. Measures include increasing the share of renewable energy, improving energy efficiency, and promoting sustainable transport.
Rapid urbanization
As cities attract more people, so does the need for electricity to power growing populations and infrastructure. Various sectors supplying these services are moving toward electrification, increasing demand and putting pressure on our grids. With renewables being the cheapest form of power today, it’s attractive for cities to invest in clean energy sources. But this also means more supply or even oversupply with grid capacity not expanding at pace. Infrastructure and space are key factors to support an effective transition. Cities must explore a range of options that best suit their unique strengths—from renewable energy and circularity of infrastructure, to repurposing industrial waste for energy supply.
Digitalization and decentralization
New digital technologies are changing the way we produce, distribute, and consume energy. Smart grids, energy storage systems, and other innovations are making it possible to generate and manage energy more efficiently. Decentralization, which allows energy to be produced and consumed locally, is another key trend in the energy transition. In the Netherlands, for example, almost 40% of the electricity supply is generated by decentralized energy systems.
Public awareness and action
Citizens and organizations are becoming more aware of the need for sustainable energy, and they are taking action to promote change. Public opinion can shape policy and investment decisions, and cities using renewable energy will be better positioned to attract residents and businesses.
Government policies and regulations
Policies and regulations like the European Green Deal, the Biden-Harris Administration’s $11 billion in grants, and the ‘Powering Up Britain’ Energy Security Plan can incentivize or mandate the use of sustainable energy sources, which can drive innovation and investment in the energy sector. Governments can also provide funding for research and development of new technologies, in partnership with the private sector.
A smarter and more efficient ideal urban system would have electricity at its core, utilizing aqua thermal and backup electricity, connecting all sectors. We must cut red tape, specifically bureaucratic obstacles, addressing congestion and permit issues, and fostering innovation through net metering and incentives.
From vision to reality: toward smart, sustainable urban energy systems
There are many opportunities in the energy transition. The rise of sustainable finance, for example, presents a major opportunity to fund energy transitions, but the effects are concentrated in advanced economies. How can we approach this so that everyone is brought along and benefits from the journey?
We need to adopt a holistic approach to urban energy systems. One that recognizes the interconnected nature of the climate challenges, energy transition, societal welfare, and spatial limitations. By taking a comprehensive ‘systems thinking’ approach to energy planning—bringing all stakeholders, including local governments, the private sector, academic institutions, the energy and resources sector, and citizens together—we can drive change across the entire urban energy ecosystem, from buildings and transport to water and waste management.
So, what needs to change today?
1. A holistic, integrated approach: stacking mobility, energy, infrastructure
Policymakers and governments facilitate progress with energy transition, but they shouldn't bear sole responsibility. Collaboration among municipalities, infrastructure providers, corporates, and logistics companies is essential.
2. Bold leadership and courage: removing the red tape and showstoppers
Insufficient support and commitments can impede the adoption of critical new technologies for advancing the energy transition. Collective action and aligned goals are key to driving meaningful progress toward cities powered by renewable energy.
Political alignment and will are crucial to implement Local Law 97 in New York, which aims to push owners to make buildings more energy efficient. Tax credits availability, fines used as deterrents, and extra grids being put in place can smooth the transition to energy efficiency. It is critical to not waste a good crisis and take advantage of opportunities to make positive changes.
3. Powering the right investments: renewable energy, energy efficiency, and resilient infrastructure
Energy investment is set to pick up, but almost half of the increase in capital spending is linked to higher costs. Cities need to invest in resilient infrastructure and measures that can withstand the escalating impacts of climate change. A large proportion of emissions in urban areas comes from buildings.
When thinking about energy opportunities, it is important to consider the unique resources available in different regions. Scotland, for example, is known for its windy climate, which makes it a prime location for wind energy. Additionally, the country also has a significant opportunity for tidal energy development. We need to work to a city’s strengths.
4. Community engagement and behavioral change: prioritizing equity and social inclusion
Efforts to drive the energy transition and enable cities using renewable energy should begin by encouraging citizens to save energy through behavioral change, focusing on small, incremental steps with immediate benefits. Implementing solutions in large buildings and social housing, like utilizing residual heat, as is the case in Antwerp for district heating networks, can kick-start progress.
5. Leveraging public-private partnerships for innovative solutions
Collaborative sustainability initiatives thrive when focused on specific areas or neighborhoods, helping test and showcase new, innovative solutions.
Charged up for change: energy systems of the future
Increasing housing density, higher costs of living, unequal access to resources, and the escalating impacts of climate change are all testing our urban spaces. Are we prepared to meet these challenges?
