How does the clean cooking industry reach rural wood collectors? While studies show that this population could afford improved cooking solutions that are under $10, there are no market-based solutions that can bring the top-tier, cleanest solutions to the 1.7 billion people who collect free biomass fuel.

Mini-grid customers’ electricity consumption is limited both by how much they can afford, and what they can do with the electricity. So why don’t customers buy more appliances and use more power?

So far, efforts to introduce cleaner stoves that burn less fuel have been led mainly by aid agencies working in rural parts of Africa and Asia – and have had limited success. But a new push by businesses targeting urban areas aims to shift the dial.

Getting power to the remotest of places —now called the last mile —is the greatest poser for governments. Power remains unaffordable to a majority of the population whose access is also limited by irregular distribution of transmission lines.

China is taking the same path that it did previously with solar panels. While solar cells were invented by American engineer Russell Ohl, today China dominates the global solar panel market. Now China is focused on controlling the world’s production of lithium ion batteries.
