Energy Efficiency

Energy efficiency requires efficient design, installation, operation, maintenance and decommissioning throughout the lifetime of a system. It cannot be regulated, yet it does not happen without regulation.

It’s the cheapest, quickest and biggest decarbonisation potential. But we can only have two out of these three. If we want cost-effective and large-scale savings, we have to follow normal renovation and replacement cycles which are steady but slow.

Hence we need to pursue energy efficiency everywhere. In addition to removing the worst products and practices from the market, we should strive for high standards.

Sometimes, 99% efficiency is poor performance. In other cases, 80% is very good.

Efficiency requires attention to minute detail. It can be a great education tool.
