A4WP gains support from an industry giant
It's not at all uncommon in the technology world for multiple organizations to be competing to become the standard for new technology. This went on in the past with the battle between Blu-ray and HD DVD among others. A new battle is brewing when it comes to wireless power with multiple organizations vying to be the standard.
The Alliance for Wireless Power (A4WP) and has added a big name to its list of supporters: Intel. “In joining A4WP, we look forward to working alongside other member companies and contributing to standards that help fuel an ecosystem of innovative solutions capable of simultaneously charging a range of devices, from low-power accessoriesto smartphones, tablets and Ultrabooks," said Navin Shenoy, Intel vice president, PC client group and general manager, mobile client platform division.
The Alliance for Wireless Power has a goal of creating a "flexible wireless power" specification wireless charging that will become an industry standard.
A4WP claims to have 50 members including some major companies in the technology realm including Broadcom, Delphi, LG Electronics, and SanDisk. The technology the company is supporting uses near field magnetic resonance charging allowing charging using a loose coupling of electromagnetic fields. The technology that A4WP is backing will allow multiple devices to be placed on a single charging pad at the same time with no need to fiddle with wires.
Competitors vying to become the industry standard for wireless charging include the
Wireless Power Consortium
Power Matters Alliance
. The Wireless Power Consortium is backing technology that is already available on the market called Qi and is being used by
, Samsung, and LG. The specification being pushed by the Power Matters Alliance is called Power 2.0. One of the biggest backers for the Power 2.0 standard is battery giant Duracell. The battery maker is backing Power 2.0 with its subsidiary, Powermat Technologies..
A4WP Chairman Kamil Grajski said his group aims to "[Remain] above the fray of the squabble that has broken out between first-generation players WPC and PMA" and "Has kept its eye on the next generation of [wireless charging] technologies and enhanced user experience through wireless charging spatial freedom."

Your link proves nothing. The California rolling blackouts in 2005, for example, happened because a transmission line went out for a reason
entirely unrelated to electricity demand
. High usage already has a feedback mechanism with utilities charging notifying businesses of days that demand is expected to be higher (and hence prices will be high).
The US absolutely has excess capacity. There's over 1000 GW of generation capacity:
Average consumption is 450 GW.
Peak consumption is 782 GW:
Near field wireless power is not going to be used for major appliances, because it costs too much. It only makes sense for things that move around a lot, like cell phones or tablets. If every household in the US charged 100 Wh of batteries a day wirelessly, then 10% loss would add up to a 0.01% increase in grid load.
So stop whining.
