The big idea: Energy security powers everything development needs — light, heat, factories, hospitals, transport and the internet. Yet billions still lack reliable energy, energy is a source of geopolitical power, and the world must now shift from fossil fuels to clean energy without leaving the poor behind.
- Powers the economy — factories, farms, offices and transport all run on energy.
- Health & education — clinics need power for equipment; children need light to study.
- Energy poverty — billions still cook on wood or charcoal, harming health and the environment.
- Energy geopolitics — control of oil and gas gives some countries power over others.
Energy, power and the clean shift: Energy is not just a resource — it is power. Countries rich in oil and gas can pressure those that depend on them, and cutting supplies can be a weapon. At the same time, the world must move from fossil fuels to clean energy to fight climate change — a shift that is an opportunity for poorer countries (cheap solar, leapfrogging dirty grids) but also a challenge (upfront cost, lost fossil-fuel income).

Without reliable energy, development stalls — factories cannot run, clinics cannot refrigerate vaccines, children cannot study after dark. But how a country gets its energy shapes its economy, environment and independence.
Why energy security matters for development
Reliable, affordable energy powers industry and jobs, lets clinics and schools function, connects people to information, and lifts households out of energy poverty. No country has developed far without securing energy, so it is a foundation of modern development.
The dilemmas of energy
Fossil fuels are cheap and reliable but drive climate change and can leave a country dependent on imports and volatile prices; renewables are clean and increasingly cheap but need upfront investment and storage; and control of energy gives some states geopolitical leverage over others.
Case study — leapfrogging to clean energy: Some developing countries show how energy can drive development in a new way. Rather than building expensive, dirty central power grids, they have leapfrogged to off-grid solar — bringing electricity to remote villages for the first time, powering lights, phones and small businesses. This cuts energy poverty, avoids fossil-fuel dependence, and shows the clean-energy shift can be an opportunity for the poor — provided the upfront cost is met, often with outside finance. It captures the modern energy-and-development challenge: securing clean, affordable energy for all without deepening inequality.
The key point: Energy security underpins development — no reliable energy, no modern economy, health or education. Energy is also geopolitical power and the front line of the climate shift, so the challenge is to secure clean, affordable, reliable energy for all without deepening dependence or inequality.

Should developing countries use cheap fossil fuels to grow, or leap to renewables? And is energy mostly a development resource or a tool of geopolitical power? Recurring debates. Weigh them.
Energy as development
Energy is first a development need: securing affordable, reliable power to run the economy, light homes and power clinics and schools, and to end the energy poverty that holds billions back.
Energy as power
Energy is also geopolitics: control of oil and gas gives producers leverage, cutting supply can be a weapon, and the clean-energy shift is reshaping which countries hold power — so energy security is tied up with independence and international power.
Two perspectives — weigh them: One view: poorer countries should use cheap fossil fuels to develop, as the rich did. Another view: they should leap to clean energy, which is now cheap, avoids dependence and fights climate change. Strong essays judge that the clean shift is increasingly the better path — especially with outside finance — but only if the poor are not left paying its upfront cost, so a just, supported transition is key.
How energy security comes up in Paper 2: A Paper 2 essay might ask whether developing countries should prioritise fossil fuels or renewables, or how far energy is a source of power in global politics. Weigh energy as development against energy as power, then judge.

Common mistakes: 1. Ignoring the upfront cost of renewables. Finance matters.
2. Forgetting energy is also geopolitics. Control of energy is power.
3. No real case. Use off-grid solar leapfrogging.
4. Listing, not evaluating. Top marks need perspectives explored AND evaluated.
5. No judgement. Conclude on the energy path and who pays.
