Centralized energy grids
Large, distant power plants to supply broad areas, offering high stability and economies of scale.
Historically favored large-scale incumbent utilities and wealthy urban centers, often shifting the negative physical and environmental impacts of infrastructure—such as massive transmission towers or generation plants—onto rural and lower-income communities
Distributed energy
Produces electricity near the point of use (e.g., rooftop solar), improving resilience and reducing transmission losses.
Energy democracy
A shift toward distributed infrastructure and renewable energy creates a new set of "winners" by enabling ____ which allows local communities, "prosumers," and marginalized groups like Indigenous peoples to capture economic rents, create jobs, and participate directly in decision-making
Harnessing the energy transition to restructure the political economy of the energy sector.
Enhanced citizen participation, economic redistribution, political geography (wind and solar require more land and involve more local actors than thermal power)

stranded assets; fuel poverty
Renewable transition creates "losers”: incumbent energy companies whose multi-billion dollar investments in old infrastructure become "____" as well as disadvantaged citizens who may face "______" if the benefits of new technologies, such as electric vehicle incentives, accrue primarily to the privileged while the costs of the transition are passed on to all consumers
NIMBY
Localization can trigger _____ opposition as energy systems become more visible in urban areas.
Decisions about grid design are never purely technical but involve constant trade-offs between different social groups.

benefits of renewable transition for developing nations
Most demand for new electricity will come from low- and middle-income countries in Africa & Asia; we have the opportunity now to ensure that much of the new power supply will be provided by low-carbon sources.
Solar could boom in countries in the global south with sunny climates.
Falling energy prices means that people’s real incomes rise. We could both reduce emissions and achieve more economic growth for the poorest places in the world.
smart grid
Digitally enabled electricity infrastructure that utilizes real-time information to coordinate generation, demand, and distribution. Provides the flexibility needed to manage the variability of sources like wind and solar. However, they note that these infrastructures could be used by utilities to monitor households rather than reflexively engaging them.
Death Spiral
Potential financial crisis where rising adoption of distributed renewable energy (like rooftop solar) reduces utility revenue, forcing them to raise rates on remaining customers, which in turn drives more consumers off the grid, causing further revenue losses

Reduced conflict; renewed conflict
Vakulchuk (vah-kool-chook) has 2 camps about geopolitics and the transition to renewable energy sources
Renewed conflict
Contends that the transition may simply replace old tensions with new ones, such as intense global competition for critical minerals and heightened vulnerabilities to cybersecurity attacks on digitalized energy infrastructure.
Reduced conflict camp
Argues that because renewable energy sources are geographically abundant and difficult to manipulate, the transition will foster energy self-sufficiency and decrease the likelihood of traditional inter-state resource wars
Renewed conflict camp
Contends that the transition may simply replace old tensions with new ones, such as intense global competition for critical minerals and heightened vulnerabilities to cybersecurity attacks on digitalized energy infrastructure.
Geopolitics
How a state exercises power over territory and geography, emphasizing the strategic importance of natural resources, location, and military-industrial leadership
Dominant mode is coercion: utilizing military force or hard economic "sticks" to ensure the security of supply and demand through the control of physical infrastructure
Geoeconomics
Building and exercising power through economic factors and international markets within an interdependent global system.
Places industrial and technology leadership over territorial control, using a spectrum of power that includes both "sticks" (sanctions) and "carrots" (investment agreements and regulatory diplomacy)
Inward-oriented toward building domestic resilience and autonomy
Outward-oriented toward shaping global production networks to make others strategically dependent on one’s own economy
petrostates
Losers of renewable energy transition: ____, fossil fuel exporters that rely heavily on oil and gas rents for national budgets and social stability.

Losers of renewable energy transition: While wealthy exporters like Saudi Arabia and the UAE have initiated proactive diversification plans to adapt, others like ____ may see a sharp decline in global reach due to their current lack of clean technology innovation.
Australia, Indonesia, Poland
Losers of renewable energy transition: Countries heavily dependent on coal: ___, ___, and ____, which face significant economic disruption as thermal power is phased out faster than other hydrocarbons. The risk of a geopolitical "backlash" from these declining powers remains a central concern during the transitional phase.

The ____ report reviews the vulnerability of fossil fuel exporters to the renewable transition.
Relatively low exposure

Malaysia: successfully followed "Hartwick’s rule" by transforming subsoil assets into reproducible physical and human capital
Bahrain and Colombia
High resilience
IRENA report: Countries with ___: These countries are "highly exposed" (meaning fossil fuel rents typically exceed 20% of their GDP) but possess the financial buffers and institutional capacity needed to reinvent themselves
The Gulf States (Saudi Arabia, UAE, Qatar, and Kuwait): While deeply dependent on oil and gas rents, these nations have high per capita GDPs and have initiated comprehensive national visions to diversify their economies
The United Arab Emirates (UAE): proactive adaptation; set a target of 44% clean energy by 2050 and utilizes its wealth to host IRENA and fund renewable projects globally, positioning itself as a hub for the new energy era
Saudi Arabia: It is noted for its "Saudi Vision 2030" plan, which aims to shield the economy from the volatility of international commodity prices through structural diversification
Brunei Darussalam: Like the Gulf states, it is categorized as highly exposed but highly resilient due to its high income levels and capacity for adaptation
Technologically Advanced Exporters
IRENA report: _____ like the United States: Although it became a net exporter of natural gas in 2017 and is nearing oil self-sufficiency, the US is uniquely positioned because it is a leader in the "clean energy race.” Its dominance in patents and new technologies like robotics, artificial intelligence, and electric vehicles ensures it can gain geoeconomic influence even as its fossil fuel assets decline in value
