Off-grid living is not measured by one global census. The clearest available statistics instead describe electricity exclusion, decentralized systems, solar-home-system access and temporary power-outage exposure, which are related but distinct populations.
Key Off-Grid Living Statistics
The most useful headline figures span global access, decentralized electricity and the consequences of unreliable power:
- In 2023, 750 million people worldwide lacked access to electricity, according to an International Energy Agency (IEA) estimate.
- In 2023, about 80% of the world’s electricity-inaccessible population lived in sub-Saharan Africa.
- In 2023, around 600 million people in sub-Saharan Africa lacked electricity access, based on an IEA estimate.
- Developing Asia’s electricity access rate rose from 79% in 2010 to 97% in 2023.
- From 2024 onward, about 135 million new electricity connections per year are needed worldwide to reach SDG 7.1.1.
- The IEA Stated Policies Scenario projects 645 million people without electricity in 2030 worldwide.
- In 2023, solar home systems provided electricity access to about 43 million people in sub-Saharan Africa.
- In 2023, solar home systems supplied access to about 4% of the sub-Saharan African population.
- In 2023, more than one-third of new electricity connections in sub-Saharan Africa came from solar home systems.
- Sub-Saharan Africa recorded more than 6.5 million new electricity connections in 2023.
- In 2023, more than 40% of sub-Saharan Africa’s population was connected to the main grid, excluding qualifying off-grid access.
- In the IEA Net Zero Emissions scenario, mini-grids account for 30% of people first gaining access by 2030.
- In the same scenario, stand-alone systems account for 25% of people first gaining access by 2030.
- Sub-Saharan African electricity access rose from around 30% in 2012 to 50% in 2024.
- In the 2023 American Housing Survey reference period, about 33.9 million U.S. households reported a complete power outage.
- During that U.S. survey period, 35.4% of rural households reported an outage, compared with 22.8% of urban households.
- 31.6% of U.S. households with electricity-dependent medical devices experienced an outage during the 2023 reference period.
- About 4.9 million U.S. housing units reported food spoilage after an outage during the 2023 reference period.

Global Off-Grid Living Statistics and Electricity Access
Electricity-access statistics describe people who do or do not receive qualifying service; they do not identify everyone who voluntarily chooses an off-grid home. The IEA estimates are based mainly on administrative data, and qualifying access can come from grid or off-grid systems.
- The number of people without electricity fell by about 10 million worldwide from 2022 to 2023.
- Around 600 million people in sub-Saharan Africa lacked electricity access in 2023, representing about 80% of the global total.
- Almost 1 billion people gained electricity access in developing Asia between 2010 and 2023, while the regional access rate increased from 79% to 97%.
- Fewer than one-fifth of African countries had targets for universal electricity access by 2030 at the time of the cited IEA report.
The pace needed to close the remaining gap is a planning measure, not observed off-grid adoption. The IEA estimates that about 135 million connections per year from 2024 would be required to reach SDG 7.1.1, while its Stated Policies Scenario forecasts 645 million people without electricity in 2030, including about 545 million in sub-Saharan Africa, or 85% of the projected total. IEA, “Access to electricity – SDG7: Data and Projections – Analysis”
| Measure | Period | Reported result |
|---|---|---|
| People without electricity, world | 2023 | 750 million |
| Share of global no-access population in sub-Saharan Africa | 2023 | About 80% |
| Projected people without electricity, world | 2030 | 645 million |
| Projected people without electricity in sub-Saharan Africa | 2030 | About 545 million, or 85% |
These figures should not be read as a count of intentional off-grid residents. They measure energy exclusion or scenario-based future access, not lifestyle preference.
Solar Home System Adoption in Sub-Saharan Africa
Solar home systems (SHS) are a major decentralized-access pathway, but the category has boundaries. The IEA notes that SHS systems up to 10 watts-peak, including pico systems, do not meet its electricity-access threshold; solar lanterns and multi-light systems therefore cannot automatically be counted as electricity access.
- SHS provided qualifying electricity access to about 43 million people in sub-Saharan Africa in 2023, or about 4% of the region’s population.
- An additional 30 million people used SHS as backup electricity in sub-Saharan Africa in 2023; backup users are not necessarily off-grid residents.
- SHS represented more than one-third of new electricity connections in sub-Saharan Africa in 2023, a share of new connections rather than the installed base.
- SHS sales in sub-Saharan Africa increased 54% in 2022 and 3% in 2023; sales can include replacements and are not equal to unique households.
- The IEA counted about 45 million people with SHS electricity access in sub-Saharan Africa in 2022, compared with an estimated 43 million in 2023; the estimates use different periods and data updates.
- SHS access in the region increased by about 25 million people from 2019 to 2022, a cumulative estimate rather than a unique-household count.
- Solar lanterns or multi-light systems benefited about 18% of the sub-Saharan African population without electricity access in 2022, but those systems did not meet the IEA access threshold.
Nigeria illustrates why sales purpose matters: in a 2022 context, backup use could represent up to 70% of off-grid solar sales. That percentage describes the purpose of sales, not the share of households using backup solar. IEA, “Electricity access continues to improve in 2024 – after first global setback in decades – Analysis” and IEA, “Access to electricity stagnates, leaving globally 730 million in the dark – Analysis”
Global SHS sales grew 4% in 2024, while sub-Saharan Africa recorded a 26% increase in new SHS primary users. These are market indicators with classification and coverage limits, not a global census of off-grid households. IEA, “Access to electricity stagnates, leaving globally 730 million in the dark – Analysis”
Mini-Grids, Stand-Alone Systems and New Connections
Connection totals combine technologies, so they are useful for tracking access expansion but cannot be substituted for off-grid participation. In sub-Saharan Africa, grids and mini-grids together provided access to more than 4 million additional households in 2023.
| Indicator | Period | Result |
|---|---|---|
| New annual electricity connections | 2019 | About 7 million people connected |
| New annual electricity connections | 2023 | More than 6.5 million connections |
| Change from the 2021 dip | 2021–2023 | 2023 total was 60% higher |
| Main-grid connection share | 2023 | More than 40% of the population |
The IEA’s 2023 connection estimate includes all connection technologies, while the more-than-4-million household figure combines grid and mini-grid access. IEA, “Electricity access continues to improve in 2024 – after first global setback in decades – Analysis”
Scenario data points toward a larger role for decentralized supply. In the IEA Net Zero Emissions scenario, mini-grids represent 30% of people first gaining access by 2030, stand-alone systems represent 25%, and almost 90% of new connections in the pathway are renewable-based.
These are forecasts, not current market shares. IEA, “Access to electricity – SDG7: Data and Projections – Analysis”
Ethiopia’s National Electrification Program 2.0 provides a policy example: it targets 35% of universal access through off-grid solutions by 2025 and provides for off-grid services to 6 million households. Those are program targets, not verified completion. IEA, “Access to electricity – SDG7: Data and Projections – Analysis”
Off-Grid Living Trends in Household Electricity Use
Access does not reveal how much electricity a household consumes or what equipment it can operate. The IEA estimates that sub-Saharan African electricity access rose from around 30% in 2012 to 50% in 2024, while average household electricity consumption among households with access fell by about one-quarter over the same period.
The decline applies to households with access, not all households and not only off-grid households. It therefore indicates a regional use trend rather than an outcome attributable to off-grid living.
System size also changes the meaning of an SHS statistic:
- The IEA’s 2024 chart notes define large SHS as 100–200 watts-peak.
- The same chart notes define small SHS as systems up to 50 watts-peak.
- In a historical IEA solar-report context, a typical SHS had peak capacity of around 100 watts.
- SHS entering the market in 2017 were estimated to give 6 million people initial electricity access worldwide.
- At the report’s historical reference point, SHS had given 12 million people electricity access in Bangladesh.
These historical SHS figures should not be presented as current global averages. Likewise, the IEA solar report’s 609 gigawatts of cumulative global PV capacity at the end of 2019 covers all photovoltaic systems, not only off-grid installations. IEA, “Access to electricity stagnates, leaving globally 730 million in the dark – Analysis” and IEA, “Solar Energy: Mapping the Road Ahead – Analysis”
U.S. Off-Grid Living Context: Outages and Rural Exposure
The United States has no authoritative national census of people who voluntarily live off-grid in the supplied evidence. The 2023 American Housing Survey instead measures temporary outage exposure, a useful indicator of why households may value backup power but not proof of off-grid residence.
- About 33.9 million U.S. households reported a complete power outage during the 12 months before the 2023 AHS interview.
- About 70% of households reporting an outage said at least one outage lasted six hours or more.
- 28.3% of homeowners reported an outage, compared with 19.9% of renters.
- 35.4% of rural households reported an outage, compared with 22.8% of urban households.
- About 14.5 million U.S. households reported medical devices requiring electricity.
The rural-versus-urban comparison is about outage experience, not the share of homes with solar, batteries or generators. The survey’s measured population is households reporting an event during the 2023 reference period. U.S. Census Bureau, “About 1 in 4 Households Experienced a Power Outage in the Span of a Year”
Off-Grid Living Outcomes: Disruption, Health and Preparedness
Outage consequences show the practical stakes of electricity continuity, but they remain conditional survey results. They do not isolate whether a household used an off-grid system, a generator, a battery or no backup equipment.
| U.S. survey outcome | 2023 AHS reference period |
|---|---|
| Households with electricity-dependent medical devices experiencing an outage | 31.6% |
| Households with at least one person with a disability reporting an outage | 28.2% |
| Housing units where someone missed work because of an outage | About 2.4 million |
| Outage-reporting households with a worker who reported missed work | 7.9% |
| Outage-reporting households reporting food spoilage | 14%, or about 4.9 million housing units |
| Households reporting refrigerated-medicine spoilage | About 705,000; 2.9% of households with refrigerated medicine |
Other reported consequences included about 2.9 million households staying away from home overnight, or 8.4% of outage-reporting households, and about 673,000 housing units experiencing frozen pipes linked to outage-related conditions. About 343,000 households reported basement or crawl-space water collection after a sump pump stopped during an outage. U.S. Census Bureau, “About 1 in 4 Households Experienced a Power Outage in the Span of a Year”
Outage exposure also varied among the 15 largest U.S. metropolitan areas in the Census comparison. Detroit had the highest reported share at 44.8%, San Francisco’s share was 36.3%, Miami had about 135,000 households, or 5.8%, and New York had 885,000 households, or 11.2% of an estimated 7.9 million households reporting an outage.
These metro figures measure outage experience, not off-grid participation or backup ownership. U.S. Census Bureau, “About 1 in 4 Households Experienced a Power Outage in the Span of a Year”
