Energy provider Genesis is preparing to launch a petition calling for a national ban on incandescent lightbulbs, citing significant potential for household electricity savings. According to Genesis chief revenue officer Stephen England-Hall, replacing inefficient incandescent bulbs with LED alternatives could save the average household $300 annually in electricity costs.
Why is a ban on incandescent lightbulbs being proposed?
The push for a ban centers on the stark difference in energy efficiency between lighting technologies. Stephen England-Hall of Genesis notes that one dollar of electricity provides 250 hours of LED lighting, compared to just 25 hours using traditional incandescent bulbs. By mandating a transition to LED technology, Genesis argues that households can achieve immediate, tangible reductions in their power bills without needing to overhaul broader electricity markets.
This proposal is not new to the New Zealand policy landscape. A phase-out was originally proposed in 2008, but the then-National government ultimately scrapped the plan. Consumer NZ has also been advocating for a similar ban for more than a decade, arguing that the technology is unnecessarily wasteful.
Research conducted by Genesis suggests that 79% of New Zealanders are already actively looking for ways to reduce their energy expenditure, with younger demographics leading the charge in seeking efficiency gains.
How can households maximize energy savings beyond lighting?
Beyond lightbulbs, Genesis highlights that behavioral changes and better utilization of existing plans are critical to lowering costs. England-Hall suggests that consumers should audit their current power plans to ensure they align with their household usage patterns. For those on day-night plans, shifting energy-intensive tasks—such as running dishwashers, washing machines, or dryers—to off-peak evening hours can result in direct savings.
Water heating also presents a major opportunity for efficiency. In a year-long trial involving 17,000 customers, Genesis found that moving morning peak hot water heating to off-peak periods saved enough energy to power 2,000 households. Because these adjustments were handled via time controls, the customers involved experienced no change in their access to hot water.
What is the long-term impact of electrifying the economy?
Industry leaders argue that broader electrification is the key to lowering unit costs across the national energy grid. According to England-Hall, increasing the electrification of the economy, including the adoption of electric vehicles (EVs), helps socialize infrastructure costs. He notes that a dollar of electricity can power an EV for 17 to 18 kilometers, whereas a dollar of diesel typically covers only three to four kilometers.
As more households and businesses shift to electric solutions, the energy system becomes more secure and efficient. Genesis reports that over 70% of surveyed individuals express a desire to reduce their total energy spend, with many feeling confident in their ability to make these changes if given the right support and information.
Frequently Asked Questions
Is a ban on incandescent bulbs officially in place?
No. While Genesis is preparing a petition to advocate for a ban, no government-mandated phase-out is currently in effect.
How much can I actually save by switching to LEDs?
According to Genesis, the average household with 15 lightbulbs could save approximately $300 per year by switching from incandescent bulbs to LED technology.
Do behavioral changes really make a difference?
Yes. Genesis trial data shows that shifting high-energy tasks like water heating to off-peak times can generate significant cumulative energy savings without impacting the end user’s comfort.
