1) The one-sentence truth

Clean energy is easy to admire. Reliable power is hard to deliver.

2) The scale (the number behind everything)

• Roughly 600 million people in Sub-Saharan Africa lack access to electricity.

• Africa’s electricity use per person is low and has flatlined in recent decades, with one widely cited figure around 530 kWh per person in 2023.

Why it matters:
Low consumption is not a lifestyle choice. It is a constraint on industry, healthcare, education, and modern jobs.

3) What lack of power blocks (real-world list)

• Clinics that cannot run basic equipment or keep vaccines cold

• Students who cannot study at night

• Businesses that cannot plan production confidently

• Digital services that cannot stay online reliably

• Households that pay more for worse energy

4) Diesel: the hidden tax

Generators are everywhere because the grid is not dependable.
A World Bank study estimates:

• millions of generator sites across developing countries

• annual fuel spending of $30 to $50 billion

• average fuel cost about $0.30 per kWh for generators

• full cost often $0.40 per kWh and higher (logistics makes it worse in remote places)

Plain English:
Diesel is not “backup”. For many, it is the main utility. At premium prices.

5) Hospitals: uptime beats ideology

WHO is clear: electricity powers basic services (lighting, communications, water supply) and enables safe procedures and immunisation.
It also notes close to 1 billion people are served by health-care facilities without reliable electricity or with no electricity access.

Plain English:
If power fails, care fails. The patient does not care what you tweeted about the energy transition.

6) Grid vs on-site: when each wins (simple decision guide)

Grid wins when:

• it is reliable most of the time

• tariffs are predictable

• connection and upgrade timelines are realistic

Onsite (solar + storage) wins when:

• outages are frequent

• diesel spend is high

• uptime is mission-critical

• you need speed and control over reliability

Best practice:
Many serious sites use both: grid when available, onsite for reliability, diesel as true emergency only.

7) The simple maths (use this calculator)

Use your own numbers. No pretending.

Inputs:
A) monthly diesel litres used
B) diesel price per litre
C) generator hours per month
D) average load in kW during generator use

Step 1: diesel cost per month
Monthly diesel spend = A x B

Step 2: kWh produced (rough estimate)
kWh per month = D x C

Step 3: your diesel cost per kWh (fuel only)
Fuel cost per kWh = (A x B) / (D x C)

Reality check:
Fuel is not the full cost. Add maintenance, oil, filters, repairs, downtime, and staff time.

8) What to do next inside the community

• Post your diesel cost per kWh (even a rough one) in the debate thread

• Ask one question about reliability risk

• Join the next Office Hours session on uptime and operations
