Haiti doesn't have a lot of wealth. Or, after the recent earthquake, infrastructure. As it is, the locals survive with kerosene stoves, and candles for lighting.
But what the locals really want, according to Discovery news, is a solar panel, because they only have to buy that once. Candles wear down and have to be bought again, but a solar and battery powered light will work day after day after day.
The article reports that even before the earthquake, 70% of Haiti had no electricity. This had negative implications on all sorts of things. Darkness proved hostile to security. (Sociopathic people interpret darkness as a lack of ability for other people to identify them, and thus license to commit crimes.) A knocked over candle is a fire hazard. Manual labor ruled the day, while electricity promises automation. There's not much you can do in the dark, in a tent.
