Questions & Answers

Q: How many people in the world have no access to energy?

Over a billion people in the world have no access to energy whatsoever.

Q: How many of these people without access to energy are in Africa?

620 million people in Africa have no access to energy, which is a significant portion of the population.

Q: How much does it cost to connect each household to the grid?

It costs approximately $1,500 to connect each household to the grid, which is a significant expense for many people in impoverished areas.

Q: How long does it typically take to connect a household to the grid?

On average, it takes about nine years to connect a household to the grid, which is a long time for those who are in need of energy.

Q: What is the current state of energy accessibility in Africa?

The current system of building grids and following traditional patterns of development is unsustainable, costing an estimated $21 billion annually to maintain. This has led to a shift towards decentralized solar solutions and distributed solar energy as a more viable and innovative option.

Q: What are some of the key roadblocks to achieving widespread access to energy in Africa?

Two main roadblocks are the intermittency of solar power, which requires better storage solutions, and the need for more efficient and diverse appliance sets. Additionally, the lack of working capital investment in this space due to difficulty in pricing consumer risk has hindered the expansion of companies in the energy sector.

Q: How can the current energy system in Africa be transformed into a fully-functioning low-carbon economy?

By promoting research and development and shifting subsidies from the current electricity system to support the creation of more efficient DC appliances and innovative energy solutions, Africa has the opportunity to become a global leader in creating a sustainable energy system.

Q: What is the vision for the future of energy access in Africa?

The vision is to create an energy system where every household acts as a producer and consumer of energy, allowing for the generation, sharing, and even sale of power within communities. This would provide people with a sense of ownership, dignity, and pride while driving industrial development and creating a fully-functioning low-carbon economy.

Summary & Key Takeaways

  • More than a billion people have no access to energy, with 620 million of them in Africa, and the cost to connect each household to the grid is around $1,500.

  • A revolution is happening in East Africa with the use of solar power and distributed solar systems, providing enough power for every household need.

  • The costs of solar productivity have significantly decreased over the last 30 years, making solar systems and appliances more affordable and accessible for households, leading to the potential for a fully-functioning low-carbon economy.
