Energy Access Isn't Just an Infrastructure Problem — It's a Design Problem

As of the most recent joint tracking report from the IEA, IRENA, the World Bank, WHO, and UN DESA, roughly 655 million people still have no access to electricity, and about two billion still cook over polluting fuels that damage their health every day. Global electrification has stalled at around 92 percent, and growth has slowed to roughly half the pace it held a decade ago. Sub-Saharan Africa carries most of that burden, and the rural gap there has actually widened over the past several years rather than closed.

Read that a second time and a pattern shows up: this isn't a story about missing technology. Solar panels, microgrids, and battery storage are all cheaper and more capable than they were ten years ago. The gap that's left is largely a design and delivery gap — figuring out who pays, who maintains, and who was actually consulted before a system gets built. That's the problem Energy Mentors' Collaborate program was set up to work on, alongside its better-known mentorship and competition work.

Why "Access" Means More Than a Wire Reaching a House

Energy access gets treated as a binary in a lot of coverage — either a household has power or it doesn't. In practice it's closer to a spectrum, and most of the meaningful differences show up after the connection exists:

• Reliability. A grid connection that fails for hours every day isn't meaningfully different from no connection for a lot of use cases — refrigeration, medical equipment, and businesses that depend on consistent power.
• Affordability. A household can be technically connected and still rationing usage because the tariff structure doesn't match what they can actually spend.
• Capacity. The most recent tracking data puts generation capacity per person at roughly 34 watts in low-income countries versus over 1,200 watts in high-income countries — a gap north of 36 to 1. A trickle of power and a reliable supply are both "access" on paper.
• Clean cooking. This is the piece that gets the least attention and remains the largest single gap — around two billion people still rely on wood, charcoal, or animal waste for cooking fuel, with direct health consequences.

None of these dimensions show up in a simple electrification percentage, which is part of why progress on the headline number can stall even as underlying conditions stay difficult for a lot of the people it's supposed to describe.

Why Building More Infrastructure Hasn't Closed the Gap

The obvious response to an access gap is to build more generation and more grid. That's been happening, and the gap has still barely moved over the past several years. A few reasons why:

Population growth is outrunning new connections. In several sub-Saharan African countries, the number of new households is growing faster than electrification programs can reach them, so the absolute number of people without power stays roughly flat even as connection rates improve elsewhere.

Financing has gotten harder, not easier. Elevated debt burdens and reduced international aid budgets have slowed public investment in exactly the regions that need it most.

Rural areas are structurally harder and get deprioritized. Grid extension into low-density, harder-to-reach areas costs more per household than urban infill, so it tends to happen last — which is exactly backward from where the need is greatest.

A lot of built infrastructure doesn't survive contact with reality. Systems designed without local maintenance capacity, without a workable payment model, or without accounting for how a community actually uses power tend to degrade quickly, sometimes within a few years of installation.

That last point is the one engineering alone can't fix. It's a social design problem wearing an infrastructure costume.

Where Social Sustainability Actually Enters the Picture

Social sustainability, in an energy access context, means the people a project serves had a real role in shaping it — not just as end users consulted after the design was finished, but as a constraint the design had to satisfy from the start. A few things that tend to separate access projects that last from ones that quietly fail:

• The payment model matches how the community actually earns and spends, not a standard tariff imported from somewhere else.
• Maintenance doesn't depend on a technician who has to travel in from outside the community.
• The people affected were part of defining what "enough power" means for their situation, rather than receiving a generic system sized off a template.
• Local institutions — a cooperative, a municipal body, a community group — have real ownership and authority over the system, not just a support role.

This is precisely the gap Energy Mentors' Collaborate program is built around: pro bono consultation for communities and public entities trying to close their own energy access gap, working alongside university partners and energy incubators rather than dropping in a prepackaged solution. It's a smaller and less visible part of the organization's work than the Power the Community design competition, but it's arguably the piece most directly aimed at the actual bottleneck described above.

What This Means for Anyone Working in the Space

If you're a student, engineer, or policy professional working on an energy access problem, the technical design is genuinely the easier half. The harder, less-taught half is the social design work: figuring out financing that fits the community, building in local maintenance capacity from day one, and treating the people affected as co-designers rather than a target population.

That's also, not coincidentally, the exact gap that experienced mentorship helps close — someone who's already watched a technically sound project fail for social reasons can flag that risk before it happens again. It's part of why Energy Mentors pairs its Collaborate work with its broader mentorship network rather than treating them as separate programs: the lessons from one consistently inform the other.

The Takeaway

Six hundred and fifty-five million people without electricity, and two billion without clean cooking fuel, isn't primarily a technology shortfall in 2026 — it's a gap in financing models, maintenance planning, and community involvement. Closing it will take the same rigor applied to social design that's historically been reserved for the engineering. That's a harder problem to solve, and a more interesting one, than just building more panels.
