Heat and light as services


in The environment

Yesterday, I read about a rather clever idea. Right now, individual homeowners (or renters) make the decisions about what kind of heating, lighting, and insulation to use. Utility firms simply sell them electricity, oil, and gas in order to meet their demands. As such, the firms have no incentive to help people conserve and, despite possible financial incentives to be more efficient, few homeowners will do so. The latter problem is clearly more acute with renters.

The alternative presented is for utility firms to sell a package of lighting and heating services instead. Then, they would have an incentive to cut power consumption and upgrade to more efficient infrastructure. They would also benefit from being able to do so at a much larger scale than individual consumers. Apparently, firms are already doing this in Woking and London.

Given how incredibly wasteful homes are when it comes to energy usage, especially in the UK, this seems like a smart way to changing incentives. Households in the UK use 25% of the total electricity generated, and produce an equivalent amount of CO2. 60% of that energy is used for heating, often in houses that are poorly insulated and were never designed to be kept at today’s room temperatures throughout.

Couldn’t the same goal be achieved by charging people proportionately more for more oil or electricity, based on a logrythm that takes into account their house’s square footage and charges them extra for the ‘extra’ fuel they use to heat the house hotter/less efficiently than a relativly efficient house would need? Then the base rate for fuel can decrease, and people who spend lots to make their houses more energy efficient can save. Allowing firms ot sell a package of lighting and heating services only works for new houses, a very small proportion of the total.

Old houses could also sign up for the services.

As for an algorithm of the kind of describe, if studies like the one described in the linked article saying that the average UK home could save £300 a year by insulating better, I really doubt such a complex system would pass the world along better. Plus, there would be considerable costs involved in calculating all the factors you describe.

Neither an algorithm nor a logarithm is required: a simple formula will do.

Define a standard of heating efficiency for each metre of house circumference. Assign a quantity of heating oil, or gas, or electricity sufficient to heat that area. Then, charge more for usage above that level.

Of course, as Milan indicates, this would involve calculations for every house in the country. It would also not take into account the possibility that some people (say, seniors or those in cold places), might need to use more even if their houses are efficient. Such as the downsides of Stalinist state-control economic models.

The biggest problem with ‘lighting and heating as service’ systems is that they might encourage people to over-consume both. This will, however, be automatically checked. If firms see such behaviour, they can establish their own pricing systems that retain profitability, probably by charging heavy users top-up fees, in the manner of many internet service providers now.

Individual, tradable carbon permits would help solve this and many other problems. Even harder to implement though.
