The Halogen Lights Have Gone Out, but What Do We Do Next?

Retailers will be allowed to sell off their existing stock, while consumers can use their halogen bulbs until they run out. However, from now on retailers must only stock more energy efficient alternatives, such as LEDs and fluorescent bulbs.

The rationale is clear. Halogens are a false economy that use around five times the energy of LEDs. They cost less initially for customers but, over time, end up more expensive than other options due to their highly inefficient energy usage. Yet, more importantly, halogens' hunger for energy causes us to generate more power and, thus, produce more CO2 emissions just to meet demand.

The ban's potential for energy and emissions savings is enormous, and vital if we are to service the continent's ever-growing need for energy. Buildings account for around

40% of our consumption and 36% of carbon emissions

in the EU. Lighting by itself accounts for

15% of UK electricity use

and leaves a substantial carbon footprint.

Through banning the bulb, we can punch a welcome hole in our total energy consumption, and reduce energy bills. Yet to make a real difference, further change must follow.

Self-conscious consumption

Some have been quick to criticise the ban for its heavy-handedness, but progress is often painful - if only for a short time. The benefits outweigh the short-term costs to suppliers and consumers, and intervention from policymakers has led to many successful environmental outcomes. The introduction of appliance energy ratings, plastic bag charges and potential taxes on plastic cups have resonated with consumers and been widely accepted.
