The conundrum of expensive and high-carbon kerosene vastly outselling inexpensive and zero-carbon solar is a defining test of humankind’s instinct for collective survival, Jeremy Leggett argues.

If we cannot quickly replace oil-for-lighting with solar lighting, he asks, given all the blindingly obvious economic and social imperatives for so doing, what chance do we have with all the many other global problems we face?

From the very front lines, as founder and chair of SolarAid, he chronicles the global community’s efforts to pass The Test, in serialised chapters as the story unfolds.
