SDG 7: Affordable and Clean Energy
Energy powers homes, schools, hospitals, businesses and transport. Yet access to reliable, affordable and clean energy is still uneven around the world. Sustainable Development Goal 7 (SDG 7) calls for access to affordable, reliable, sustainable and modern energy for everyone by 2030.
Why clean energy matters
Many communities still lack dependable electricity or rely on polluting fuels for cooking and heating. These conditions can affect health, education, safety and opportunities to earn a living. At the same time, producing energy from fossil fuels releases greenhouse gases that contribute to climate change and can worsen air pollution.
Clean energy—including solar, wind, hydropower and geothermal power—can help reduce these impacts. When developed responsibly, renewable sources can provide electricity with much lower emissions than fossil fuels. Energy efficiency also matters: better-insulated buildings, efficient appliances and improved industrial processes can reduce the amount of energy needed in the first place.
What SDG 7 aims to achieve
SDG 7 sets out several connected priorities: ensuring universal access to affordable and reliable modern energy; increasing the share of renewable energy; improving the rate of energy efficiency; and expanding international cooperation and investment in clean-energy technology and infrastructure.
These goals are interdependent. Renewable power needs suitable networks and energy storage to deliver electricity when and where it is needed. Clean cooking solutions must be affordable, practical and suited to local needs. And energy systems must be designed to serve rural and remote communities as well as cities.
Challenges and opportunities
Progress can be held back by the cost of infrastructure, limited access to finance, unreliable electricity networks and shortages of technical expertise. Some communities also face barriers linked to geography, poverty or discrimination. A transition to clean energy must therefore be fair as well as fast: workers and regions affected by changes in the energy sector need support, and the benefits of new projects should be shared with local communities.
There are many ways to accelerate progress. Governments can set clear policies and invest in modern electricity networks. Businesses can improve energy efficiency and choose cleaner sources of power. Researchers can develop technologies that make renewable energy more affordable and dependable. Community organisations can help ensure that projects reflect local priorities.
How individuals can contribute
People can support SDG 7 by reducing avoidable energy use, choosing efficient products and, where practical, switching to renewable electricity. Taking public transport, cycling or walking can also reduce energy demand. Individuals can ask local representatives and businesses about their energy plans and support policies that make clean energy accessible to everyone.
A shared responsibility
Affordable and clean energy is not only an environmental issue; it is essential for health, opportunity and sustainable development. Reaching SDG 7 requires cooperation between governments, communities, businesses and individuals. By expanding access while reducing emissions and improving efficiency, societies can build energy systems that are more reliable, inclusive and fit for the future.

Reduces greenhouse gas emissions
Clean energy helps reduce greenhouse gas emissions by replacing fossil fuels such as coal, oil and gas with renewable sources like wind and solar power. Generating electricity this way produces little or no greenhouse gas emissions during operation, helping to limit climate change and support healthier, more sustainable communities.
Improves air quality
Clean energy can improve air quality by reducing reliance on fossil fuels such as coal, oil and gas, which release harmful pollutants when burned. Increasing the use of renewable sources, including wind and solar power, can help cut emissions that contribute to smog and respiratory illness. Cleaner air benefits everyone, particularly children, older people and those with heart or lung conditions, while helping make communities healthier and more pleasant places to live.
Helps tackle climate change
Clean energy helps tackle climate change by replacing fossil fuels such as coal, oil and gas, which release greenhouse gases when burned. Solar and wind power produce electricity with very low emissions during operation, while using energy more efficiently can reduce overall demand. Expanding these solutions can cut emissions, slow global warming and support a healthier, more sustainable future.
Expands access to reliable electricity
Clean energy can expand access to reliable electricity, particularly in rural and remote communities that are not connected to the main power grid. Solar panels, wind turbines and small-scale renewable systems can generate power close to where it is needed, helping homes, schools, health centres and local businesses operate more consistently. This can support learning, improve healthcare and create new economic opportunities, while reducing dependence on costly or polluting fuels.
Supports better health
Clean energy supports better health by reducing air pollution from coal, oil, gas and polluting cooking fuels. Cleaner air can lower the risk of respiratory and heart conditions, while safer cooking options reduce exposure to harmful smoke inside homes. Reliable electricity also helps hospitals and clinics power essential equipment, store medicines and provide better care to their communities.
Creates green jobs
Clean energy can create green jobs across a wide range of sectors, from manufacturing solar panels and wind turbines to installing, maintaining and operating renewable energy systems. It can also support work in energy-efficient construction, research and sustainable transport. With suitable training and fair employment opportunities, the growth of clean energy can strengthen local economies while helping communities move towards a lower-carbon future.
Can lower energy costs over time
Clean energy can lower energy costs over time. Although installing technologies such as solar panels or wind turbines may require a significant upfront investment, they use freely available resources and can reduce reliance on costly fossil fuels. Once in place, they can help households, businesses and communities benefit from more predictable energy bills and lower running costs. Improvements in energy efficiency can also reduce overall consumption, bringing further savings in the long term.
Strengthens energy security
Clean energy strengthens energy security by diversifying how countries produce and supply power. Using local renewable sources such as wind and solar can reduce reliance on imported fossil fuels, helping protect communities from supply disruptions and sudden price rises. Combined with energy storage and resilient electricity networks, clean energy can support a more dependable energy system for the future.
Powers sustainable development
Clean energy powers sustainable development by providing reliable electricity for homes, schools, hospitals and businesses while reducing greenhouse gas emissions and air pollution. Access to affordable renewable energy can support education, improve health, create jobs and help communities grow without depending on finite fossil fuels. In this way, clean energy contributes to economic and social progress while protecting the environment for future generations.
Renewable energy can be intermittent.
One challenge of renewable energy is that its supply can be intermittent. Solar panels generate less electricity on cloudy days and none at night, while wind turbines depend on suitable wind conditions. This can make it harder to match electricity supply with demand, particularly when renewable sources provide a large share of the energy mix. Energy storage, flexible electricity networks and a diverse range of power sources can help manage these fluctuations, but they may require significant investment.
Building infrastructure can be costly.
Building clean-energy infrastructure can be costly. Solar farms, wind turbines, energy storage and upgraded electricity grids require substantial investment, as well as ongoing maintenance. These upfront costs can be especially difficult for lower-income countries and communities, where access to finance may be limited. Without careful planning and fair funding, the expense could slow the transition to clean energy or leave some people unable to benefit from it.
Projects may affect local habitats and communities.
Clean energy projects can bring important environmental benefits, but they may also affect local habitats and communities. Wind farms, solar parks, dams and new power lines can alter landscapes, disturb wildlife or take up land used for farming and housing. If local people are not consulted or fairly compensated, projects may disrupt livelihoods, cultural sites and access to resources. Careful planning, environmental assessments and meaningful community involvement can help reduce these impacts and ensure the benefits are shared fairly.
