Much of Colombia is mountainous, and (in my experience) most towns in the mountains are situated by high-volume rivers and streams. I'm told that 50 years ago or so it was quite common for small towns to have hydro-power, but then the government strung up wires from far away coal-powered electricity plants, and that was the end of that. Perhaps such towns could be incentivized to install/reinstall hydro power, and achieve some degree of energy self-sufficiency. I have no idea whether the incentive could reasonably be price-based, as coal seems cheap. Additionally, the sun is almost always shining in the Colombian Andes, and I've never seen a solar panel.
