Charging forward on environmental protection
In the effort to foster better energy efficiency practices, PMA strives to be part of an industry-wide shift towards DC current.
There are three contributing factors to this turnaround: Wireless transmission of power is accomplished exclusively in Direct Current formats; battery powered devices – a major beneficiary of the emerging wireless charging spot paradigm – consume power in DC only; and perhaps most significantly, renewable energy sources, such as wind and solar, natively produce energy in DC current.
So it’s not just about impacting smarter practices and savings on the consumer end, but redefining the entire supply chain from environmentally-friendly power generation through targeted, need-based delivery.
Wireless power, as envisioned by the PMA, promises to streamline energy usage by adding a layer of intelligence to powering the mobile computing and communications devices that enable today’s fast-paced lifestyles and make anywhere always-on access possible.
The introduction of wireless charging means that embedded energy – the energy expended for the production, shipment and disposal of legacy chargers – will be significantly reduced as those devices are gradually phased out. Studies show the inherent eco-friendly potential of wireless power. It is estimated that by 2020 wireless charging could offset the equivalent of 289.4 million metric tons of CO2 and the equivalent of 482 100MW power plants. These saving could amount to a cancellation of the entire embedded energy usage of external power supplies by over 118%, thereby saving the unnecessary disposal of an estimated 4.5 billion transformers and associated toxic components into landfills.
By promoting policies and practices that contribute to energy efficiency and education throughout the supply chain, the PMA hopes to impact the wireless power paradigm discussion from an environmental perspective at both ends and at all points in between.
