How much does it cost to charge an iPhone 6? A remarkably slender $0.47 per year

Many aspects of Apple’s newly released iPhone 6 line are indeed, as the company has stated, “bigger than bigger.” From screen size to sales numbers, the new devices pack a hefty punch.

But at least one thing about the iPhone 6 and iPhone 6 Plus is spectacularly small: their energy consumption.

Following up on our iPhone 5 analysis a couple years ago, we returned to the Opower lab to measure how much electricity it takes to charge the latest Apple devices from 0% to 100% full. Then we modeled those results across a year (see Methodology) to determine their annual energy impact and cost.

Charging the iPhone 6 costs $0.47 per year

We found that, like their predecessor, the iPhone 6 as well as the iPhone 6 Plus require a trivial amount of electricity:

STAT OF THE WEEK: Los Angeles shatters its record for peak electric demand, twice

Stat of the Week

In the face of sizzling temperatures this week, the City of Angels saw its demand for electricity shoot up toward the heavens.

First, on Tuesday, near-100 degree temperatures meant a big spike in air-conditioning that catapulted LA’s total power draw to 6,196 megawatts – surpassing a previous all-time record of 6,177 megawatts set in September 2010. This level is around double the amount of electric demand experienced during a typical day in LA.

Wednesday took things a step further: in the midst of triple digit temperatures in downtown LA (high of 104°F), the LA Department of Water and Power reported peak power levels of 6,396 megawatts.

Are solar panels and energy efficiency 2 sides of the same roof? A new research report says yes.

A new research report from sunny San Diego uncovers some interesting connections between two major forces in the residential energy space: rooftop solar and energy efficiency.

The report, “Energy Efficiency Motivations and Actions of California Solar Homeowners,” presents survey findings from 2,300 San Diego homeowners who had installed a rooftop solar system prior to June 2012, specifically looking at these households’ perspectives on energy efficiency.
