Energy is one of the most important enablers of a modern society. Without a ready supply of high density energy in the form of hydrocarbons, we could not have built the modern industrial technocracy we now live in. Of course, we are now also quiet familiar with the side effects of cheap fossil fuel.

Our energy supply is the one thing holding us back from stopping enormous amounts of pollution. Finding non-polluting forms of energy is therefore of the greatest urgency. The Rapid Emissions Reduction scenarios from Tyndall Centre are based upon the conservative assumption that we are still going to be dependent on fossil fuels for our energy needs. Hence, the need to severely curtail usage until renewables have scaled to the extent that they can take over from polluting fossil fuels. But what if there were other feasible forms of energy production that could scale rapidly? This challenge looks at some of these…mostly distributed energy systems that can be used at household or community level. Community level systems require some kind of community level distribution system such as mini-grid for electrical AC/DC distribution or a hydrogen system.
