Iran Strait of Hormuz Closure Highlights Role of Energy Diversity in US Policy

The closure of the Strait of Hormuz by Iran has disrupted global energy supplies, demonstrating how energy resources can serve as a weapon in international conflicts. This situation arises amid tensions from the Trump administration's military actions against Iran, which began without extensive pre-conflict diplomacy to secure allied support.

The Strait of Hormuz, a critical chokepoint for oil shipments, affects global trade routes and energy prices.

The Trump administration has pursued a policy of US energy dominance by focusing on fossil fuels and nuclear power, while limiting renewable energy development. This approach includes actions to halt renewable projects, such as pressuring the French energy firm Total to withdraw from a planned offshore wind project on the US East Coast.

In exchange, the administration plans to refund approximately $1 billion in concession fees paid by Total to the US Treasury and permit investment in fossil fuel projects in Texas.

US electricity demand is expected to increase by 25 percent by 2030 and 78 percent by 2050, according to projections. This growth stems from near-term factors like manufacturing and AI data centers, and long-term trends including the electrification of heating and transportation. Meeting this demand will necessitate substantial new power generation capacity.

Renewable energy sources, such as solar and wind, currently produce electricity at a lower cost per megawatt-hour than new coal or natural gas plants, even without subsidies. The cost advantage of renewables has expanded over the past decade. Fossil fuel plants require ongoing fuel purchases, exposing them to price fluctuations, as observed in the current Strait of Hormuz situation.

Renewables also deploy more quickly; for instance, new natural gas plants face delays into the 2030s due to a 50-month backlog for gas turbines, while nuclear plants can take over a decade to become operational.

Texas, despite its fossil fuel resources, leads the US in installed wind generation capacity and ranks second in solar generation. These developments have contributed to lower wholesale electricity prices for Texas utilities compared to many other states.

The US Energy Information Administration reports that, based on data through January, renewable energy sources are increasing their share of power generation capacity, while coal and natural gas shares are declining.

Solar, wind, and battery storage accounted for the majority of power capacity additions in the first 12 months of the Trump administration. Further growth in renewables is projected for 2026. This trend reflects broader shifts in energy production amid rising demand and policy decisions affecting project approvals and investments.
