Falling Solar Costs Transform Energy Economics for Nations

Key Moments

Energy Crisis Highlights Diverging European Paths

Renewable energy has moved to the forefront as the Iran war intensifies pressure on Europe’s oil and gas supplies. Within the region, countries are taking different approaches to secure their power systems.

Italy has chosen to delay the permanent closure of its coal-fired power plants in response to this heightened energy uncertainty. In contrast, Spain has seen comparatively steady electricity prices, a development linked to its decision to double its wind and solar capacity since 2019.

Solar Delivers Major Cost Savings for Europe

New analysis from SolarPower Europe underscores the financial impact of the region’s growing solar capacity. According to the organization, using solar power has generated savings of more than €100 million per day for Europe since 1 March. Over that period, the cumulative benefit has exceeded €3 billion.

Electrotech Barriers in Low-Income Countries

Despite these gains in advanced economies, the report notes that electrotech – including solar, battery storage, and electric end-use applications – has historically been out of reach for many low-income countries. Higher upfront investment requirements have limited adoption and constrained the potential for a broader clean energy rollout.

A new study from energy think tank Ember points to a turning point that could extend these technologies to the roughly one billion people who have been left out by the fossil fuel-based system.

Emerging Economies and the Persistent Access Gap

Ember highlights the long-standing difficulties smaller emerging economies face in advancing along the energy development path. The report states that more than 700 million people still lack access to electricity. Even among those with grid connections, power reliability remains a major issue, with frequent outages reported.

The situation is especially acute in the 74 member states of the Climate Vulnerable Forum (CVF). Collectively, these nations host over one-fifth of the world’s population, yet they represent less than five per cent of global GDP and electricity demand.

According to the report, structural obstacles have limited the effectiveness of the traditional fossil fuel development model for these countries. Ember writes: “The conventional fossil-based development model has failed to reach them at scale. For countries with limited state capacity and high borrowing costs, this lumpy, centralised, capital-intensive fossil path has always been a tall order.”

A New Development Path Driven by Electrotech

Ember argues that falling costs and wider availability of electrotech are transforming the economic case for cleaner energy in emerging markets.

Daan Walter, Principal of Ember Futures, states: “It has long been argued that the only path to economic development needs fossil fuels. But the current energy crisis has again exposed how fragile that path is, especially for emerging economies that spend billions each year on fuel imports.”

Walter continues: “The difference today is that a credible alternative development path exists: electrotech is now cheaper, widely available, easily scalable, and offers the prospect of energy independence and abundance to drive growth.”

Cost Dynamics: Solar vs Fossil Fuels

The report notes a significant shift in capital requirements for new generation. Solar projects now demand less upfront capital than fossil fuel-based options. This marks a reversal from conditions a decade ago, when solar assets could require up to five times more initial investment than comparable fossil fuel facilities.

Off-grid solar-plus-battery systems have also reached a tipping point. For communities situated more than a few dozen kilometers from existing transmission lines, these systems already offer a better economic proposition than extending the central grid.

Rapid Uptake of Electrotech in Climate Vulnerable Forum Nations

Ember’s analysis indicates that CVF member countries are beginning to adopt these technologies at a notable pace. When measured by electricity demand, roughly half of CVF nations have already surpassed the United States in terms of solar penetration. A similar share has also moved ahead of the United States in electrification levels.

This acceleration in adoption is framed by CVF leadership as a structural turning point. Sara Jane Ahmed, Managing Director and V-20 Finance Advisor of CVF-V20, says: “This is an epochal shift in humanity’s energy story, and vulnerable developing countries are at the heart of the increasingly rapid electrotech transition towards clean energy futures and climate prosperity.”
