From Oil Shock to Energy Security: How the Iran Conflict Could Accelerate California’s Renewable Future
For decades, renewable energy was discussed primarily as an environmental solution. Today, it is increasingly viewed as something just as important: a national security and economic resilience strategy.
The 2026 conflict involving Iran and the disruption of oil and natural gas shipments through the Strait of Hormuz have demonstrated how quickly events thousands of miles away can affect fuel prices, transportation costs and business operations in the United States.
The International Energy Agency describes the current situation as the world’s largest energy security crisis to date. It expects the disruption to leave a lasting mark on global investment as governments seek more domestically available energy, stronger electrical systems and greater efficiency. Of the projected $3.4 trillion in worldwide energy investment during 2026, approximately $2.2 trillion is expected to flow into electricity grids, energy storage, renewable power, nuclear energy, efficiency and electrification.
The message is becoming difficult to ignore: countries that depend heavily on imported fossil fuels remain vulnerable to conflicts, blockades and sudden price shocks.
Energy That Does Not Depend on Tankers
Oil and liquefied natural gas must be extracted, processed, transported and delivered through complex international supply chains. A conflict near a major shipping route can interrupt those supplies almost immediately.
Solar panels and wind turbines operate differently. Once installed, they do not require continuous deliveries of purchased fuel. A rooftop solar system, community microgrid or regional wind farm cannot be cut off from sunlight or wind by the closure of a foreign shipping channel.
Renewable infrastructure is not invulnerable. Electrical grids, control systems and energy-storage facilities must still be protected from physical damage, extreme weather and cyberattacks. However, distributed generation reduces dependence on a small number of distant suppliers and creates more options for maintaining essential services during a crisis.
When solar generation is combined with battery storage, organizations may be able to maintain critical systems during outages, reduce peak electricity demand and improve overall business continuity.
Greater Protection From Volatile Energy Prices
Fossil-fuel prices are affected by geopolitical events, production decisions, transportation costs and global demand. Businesses rarely have control over any of these factors.
Renewable energy requires a significant initial investment, but sunlight and wind do not carry a fuel charge. That gives renewable projects greater long-term cost predictability once they are operating.
This does not mean electricity prices will never increase. Grid maintenance, financing, transmission, insurance and equipment replacement still have costs. Renewable energy can, however, reduce exposure to the dramatic commodity-price swings that often follow international conflicts.
For businesses, greater predictability can support more accurate budgeting and reduce the risk that a distant crisis will suddenly increase operating expenses.
Transportation Is Part of the Security Equation
High gasoline prices also make electric vehicles more attractive. Every driver or commercial fleet that moves from gasoline to electricity permanently reduces some demand for petroleum.
Electric vehicles do not eliminate energy costs, but they allow transportation to draw power from a much broader mix of resources, including solar, wind, hydroelectricity, nuclear energy and battery storage. As the electrical grid becomes cleaner and more diversified, transportation becomes less dependent on imported oil.
Federal clean-vehicle tax credits are no longer available for vehicles acquired after September 30, 2025, creating a new affordability challenge for consumers and businesses considering electrification. California has responded by developing additional state-level incentives.
California’s Clean-Energy Progress
California remains one of the country’s most aggressive clean-energy markets. Under Senate Bill 100 and related legislation, the state is targeting:
- 60% renewable and zero-carbon retail electricity by 2030
- 90% clean electricity by 2035
- 95% by 2040
- 100% by 2045
In 2024, approximately 45.2% of California’s retail electricity came from Renewables Portfolio Standard-certified resources. When large hydroelectric and nuclear generation are included, zero-carbon sources supplied approximately 67% of retail electricity sales.
The state is also demonstrating that high levels of clean generation can operate at meaningful scale. During 2025, clean resources met or exceeded demand on the California Independent System Operator grid for at least part of 279 days. Those periods totalled more than 1,856 hours—the equivalent of approximately 77 full days of 100% clean electricity.
California has expanded the infrastructure needed to support that progress. By October 2025, the state reported adding 30,800 megawatts of clean-energy generation and storage capacity since 2019.
Battery storage is particularly important because it allows excess solar electricity generated during the day to be stored and delivered during the evening, when demand remains high but solar production declines.
Cleaner and More Efficient Buildings
California’s updated Energy Code took effect on January 1, 2026. It applies to new buildings, major renovations and certain additions and alterations.
The standards expand the use of energy-efficient heat pumps, encourage buildings to be ready for further electrification, strengthen ventilation requirements and promote strategies that shift electricity use away from periods of peak demand. State estimates indicate that the updated code could save Californians nearly $5 billion in energy costs over 30 years.
These changes matter to businesses because buildings are becoming active components of the energy system. Solar generation, batteries, smart controls, connected heating and cooling systems, EV chargers and automated energy-management platforms must all communicate securely.
That creates opportunities for efficiency, but it also expands the organization’s technology and cybersecurity responsibilities.
New Support for California EV Buyers
California’s new MyFirstEV program is expected to begin later in the summer of 2026. The program is designed to provide an immediate point-of-sale rebate for Californians purchasing their first zero-emission vehicle.
The announced incentives include:
- $3,500 toward a new electric vehicle with an MSRP of up to $50,000
- $1,750 toward a used electric vehicle priced at up to $25,000
- Eligibility for California residents purchasing their first zero-emission vehicle
The state is contributing $135.5 million, with participating automakers expected to provide matching support, creating a combined $270 million program.
Income-qualified residents may also qualify for the statewide Driving Clean Assistance Program. Depending on income, location and whether an older vehicle is retired, participants may receive as much as $12,000 toward a vehicle and another $2,000 for charging.
Because incentive availability can differ by utility territory and regional air district, consumers and businesses should use California’s DriveClean incentive search tool to identify programs available in their area.
California has also adopted a policy framework intended to have all new passenger vehicles meet zero-emission standards—including qualifying plug-in hybrids—by the 2035 model year. Federal attempts to revoke California’s authority have placed parts of that framework in active litigation, but the state continues to pursue its broader clean-transportation strategy.
What This Means for California Businesses
The transition to renewable energy is not simply about replacing one type of power plant with another. It is changing how businesses approach operations, facilities, transportation and technology.
Organizations should begin evaluating:
- Energy resilience and backup-power requirements
- Solar, battery and microgrid opportunities
- Fleet electrification and workplace charging
- Smart-building controls and energy-management platforms
- Cybersecurity for connected operational technology
- Business continuity during grid or fuel-supply disruptions
As energy infrastructure becomes more connected, the distinction between information technology and operational technology continues to narrow. EV chargers, battery systems, building controls and distributed power equipment are all potential network endpoints. They must be properly configured, monitored, updated and protected.
The conflict involving Iran may eventually subside, but the lesson it has delivered will remain. Energy systems that depend on vulnerable international supply routes create strategic and economic risks. Locally generated electricity, diversified energy resources, battery storage and electrified transportation can help reduce those risks.
Renewable energy is therefore becoming more than a response to climate change. It is part of a broader strategy for price stability, technological modernization, national security and long-term business resilience.
For California organizations, the transition is already underway. The next challenge is ensuring that the technologies supporting it are reliable, secure and ready for the demands of the future.
