"Natural Fuse" harnesses the carbon-sinking capabilities of plants to create a city-wide network of devices that act both as electricity outlets and as a shared resource that offsets CO2 generated in the production of that electricity.

Natural Fuses allow only a limited amount of energy to be expended; that amount is limited by the amount of CO2 that can be absorbed by the plants that are growing in the system - natural "circuit breakers". By networking them together, the plants are able to share their capacity and take advantage of carbon-sinking-surplus in the system since not all Natural Fuses will be in use at any one time.

If people cooperate on energy expenditure then the plants thrive (and everyone may use more energy); but if they don't then the network starts to kill plants, thus diminishing the network's electricity capacity.
