Energy Insecurity & Sustainable Solutions

Energy insecurity affects billions of people worldwide. While some countries have abundant energy resources, others struggle to meet basic energy needs. This lesson examines the causes and consequences of energy insecurity, explores sustainable energy solutions, and evaluates large-scale energy projects. Understanding these issues is essential for the AQA GCSE Geography exam.

What Is Energy Insecurity?

Energy insecurity occurs when a country or community does not have reliable access to affordable energy to meet its needs. This can mean:

• Insufficient electricity generation to power homes and businesses
• Dependence on imported energy, making a country vulnerable to price changes and supply disruptions
• Energy poverty — when households cannot afford to adequately heat or power their homes

The Scale of the Problem

• Over 750 million people worldwide lack access to electricity
• Approximately 2.4 billion people rely on traditional biomass (wood, charcoal, animal dung) for cooking, causing indoor air pollution
• Energy poverty exists in HICs too — in the UK, around 6.5 million households are in fuel poverty

Causes of Energy Insecurity

Cause	Explanation	Example
Lack of domestic resources	Some countries have few fossil fuel reserves and limited renewable potential	Japan imports over 90% of its energy
Physical factors	Climate, geography, and geology determine energy resource availability	Iceland has geothermal; Saharan countries have solar potential
Political instability	Conflict and poor governance disrupt energy production and investment	Nigeria — oil-rich but plagued by pipeline sabotage and corruption
Poverty	Poor countries cannot invest in energy infrastructure	Many Sub-Saharan African nations lack power grid coverage
Rising demand	Population growth and industrialisation outstrip energy supply	India's energy demand is growing faster than its domestic production
Geopolitical tensions	Energy can be used as a political weapon	Russia's gas supply restrictions to Europe (2022)
Climate change	Drought reduces hydroelectric output; extreme weather damages infrastructure	Brazil's hydroelectric output fell during the 2021 drought

Consequences of Energy Insecurity

Economic Consequences

• Industrial output falls — factories cannot operate without reliable electricity
• Investment deterred — businesses avoid countries with unreliable power supplies
• Fuel poverty — households spend a disproportionate share of income on energy
• Transport disruption — fuel shortages affect road, rail, and air transport
• Higher costs — energy price rises increase the cost of goods and services

Social Consequences

• Health impacts — indoor air pollution from burning biomass kills approximately 3.8 million people per year (WHO)
• Education — children cannot study after dark without electricity
• Gender inequality — women and girls in LICs spend hours collecting firewood for cooking
• Quality of life — without energy, there is no refrigeration, heating, lighting, or communications

Environmental Consequences

• Deforestation — communities without modern energy fell trees for firewood and charcoal
• Air pollution — burning biomass and coal produces particulates and greenhouse gases
• Climate change — fossil fuel dependence drives global warming

Exam Tip: When discussing consequences of energy insecurity, organise your answer into economic, social, and environmental categories. This demonstrates clear structure and analytical thinking — exactly what examiners are looking for.

Sustainable Energy Solutions

Micro-Hydro Schemes

Small-scale hydroelectric systems that generate electricity from rivers and streams without large dams:

• Capacity: typically 5–100 kW — enough for a village or small community
• Advantages: low environmental impact, no displacement, community-managed, reliable
• Disadvantages: site-specific, limited output, seasonal variation
• Example: thousands of micro-hydro systems operate in Nepal, providing electricity to remote mountain communities

Solar Home Systems

Individual solar panels and batteries that provide electricity to off-grid households:

• Used extensively in Bangladesh, Kenya, and India
• Companies like M-KOPA Solar provide systems on a pay-as-you-go basis using mobile phone payments
• Advantages: zero emissions, no fuel costs, empowers remote communities
• Disadvantages: intermittent (night, cloudy days), battery replacement costs, limited power output

Improved Cookstoves

Replacing traditional open fires with efficient cookstoves that use less fuel and produce less smoke:

• Advantages: reduce wood consumption by up to 60%, dramatically reduce indoor air pollution, save time collecting fuel
• Disadvantages: cost can be a barrier, cultural resistance to changing cooking methods
• Impact: the WHO estimates improved stoves could prevent millions of premature deaths from indoor air pollution

Community Wind Projects

Small-scale wind turbines owned and managed by local communities:

• Example: Gigha in Scotland — community-owned wind turbines generate income and electricity for the island
• Advantages: local ownership, revenue stays in the community, clean energy
• Disadvantages: intermittent, maintenance costs, limited output

Case Study: Large-Scale Energy Development — Chambamontera Micro-Hydro, Peru

Background

In Peru's remote northern highlands, the village of Chambamontera lacked electricity. The community partnered with the NGO Practical Action to build a micro-hydro scheme.

The Project

Feature	Detail
Location	Chambamontera, Cajamarca region, northern Peru
Technology	Micro-hydro turbine powered by a diverted mountain stream
Capacity	15 kW — enough to supply 60 families
Cost	Low — built using local materials and labour
Management	Run by a local committee; families pay a small monthly fee

Benefits

• Families have electric lighting for the first time — children can study after dark
• Reduced dependence on kerosene lamps (which cause fires and respiratory problems)
• Small businesses have started — a carpentry workshop, a bakery, a phone charging station
• Reduced deforestation — less wood needed for light and heating
• Women and girls spend less time collecting fuel

Limitations

• Output is limited — cannot power heavy industry or large appliances
• Seasonal variation — output depends on river flow, which varies with rainfall
• Maintenance requires some technical knowledge — the community needed training

Exam Tip: Micro-hydro and other small-scale renewable projects are strong examples for questions about sustainable energy in LICs. They demonstrate how appropriate technology — affordable, locally managed, and environmentally friendly — can transform communities without the massive costs and disruption of large-scale projects.

Evaluating Energy Strategies

When evaluating energy strategies in the exam, consider these factors:

Criterion	Questions to Ask
Reliability	Can this source provide energy 24/7, or is it intermittent?
Cost	What are the capital costs vs running costs? Is it affordable for the country?
Environmental impact	What are the carbon emissions? What is the impact on ecosystems and landscapes?
Social impact	Does it displace communities? Does it create jobs? Who benefits?
Scalability	Can this solution be expanded to meet growing demand?
Energy security	Does this reduce or increase dependence on imported energy?
Sustainability	Will this still be viable in 50 or 100 years?
