Industry leaders at a recent climate change discussion organised by the ICE and Royal Academy of Engineering concluded there was 'no point developing (energy-saving technology) in a market where only the cheapest, dirtiest option survives' (NCE 17 May).
Anthony White of Climate Change Capital suggested that the only way forward was 'to convince energy companies they can make as much money selling fewer units of electricity.' The conclusion was that 'pouring heat and power into a house is cheaper than installing energy efciency measures'.
This is not necessarily so. Imagine that someone discovered a through-the-wall passive vent that:
-Saves 30% of household energy -Reduces carbon footprint by 20% -Alleviates draughts irrespective of wind direction -Improves ventilation of single-sided dwellings -Permits installation from inside highrise buildings -Avoids risk of CO poisoning caused by side winds -Was available in 100mm and 150mm diameter and three colours -Conforms to building regulations.
Wouldn't they buy it immediately, especially when they discovered that the initial outlay could be recouped within a year after installation and they would reduce their energy bill by £200/year thereafter?
It's already on the market and the energy companies don't come into it.
