Strategies exist, through which the cost of electricity in the domestic setting can be cut to zero.
One strategy for cutting the cost of electricity to zero in the domestic setting is that of leveraging on solar power.
Another strategy for cutting the cost of electricity to zero in the domestic setting is that of crafting technologies through which the kinetic energy generated in ordinary domestic processes is turned into electrical energy through dynamos. This is the approach used to power cars: whether their batteries are charged using the alternators through the kinetic energy generated as they move. We can reckon that without this sort of arrangement, the cost of electricity in cars would be very high. It would, almost certainly, be higher than the cost of the general car insurance whose workings’ descriptions you can find on this post.
Yet another strategy for cutting the cost of electricity to zero in the domestic setting is that of leveraging on the power of biogas technology. Under this scheme, the biogas generated in the home (from the various forms of waste) can be converted into electricity which, in the absence of very power-intensive appliances, can be adequate for a typical home’s needs.
