From a 2,400MW power surge during the royal wedding to 18,000 engineering staff at BAE - here are the numbers dominating the news this month


Britain’s power grid experienced a demand surge of 2,400MW on 29 April as television coverage of Prince William’s marriage to Catherine Middleton handed back to the studios when the couple reached Buckingham Palace.

National Grid prepared a forecast of likely changes in demand based on previous royal weddings, bank holiday patterns and other factors. Engineers in the grid operator’s control room managed a series of surges and drops in demand during the morning, but the highest jump exceeded both the predicted 1,200 to 1,600MW and the 1,800MW that was the largest surge during Prince Charles’ wedding to Lady Diana Spencer in 1981.

Over 350 million consumer devices shipped with HDMI in 2010, according to research by In-Stat. The HDMI specification combines high-definition video and multi-channel audio in one digital interface. It is used in nearly all new digital televisions, Blu-ray and DVD players and recorders, is increasingly found in cameras and camcorders, and is gaining traction in mobile PCs, graphics cards, and PC monitors.


Market demand for LEDs will be dominated by TV applications until 2013, according to research by DisplaySearch, but LED lighting will capture the lead by 2014.

LED backlights are used in most small and medium-sized liquid crystal displays and mobile PCs, and penetration in monitors and TVs continues to grow, but the number of LED packages per set is increasing more slowly and is set to peak in 2012. This is driven by increasing efficacy of LEDs which, coupled with a falling cost per chip, is making them a more attractive option for general illumination. LED spotlight and street light sales will be boosted by government incentives in China.


BAE Systems is the UK’s largest single private-sector employer of professional engineers with 18,000 engineering staff in 2009, according to a report produced for the company by Oxford Economics. It is also the country’s largest manufacturing-based employer.


Apple has become the most valuable brand in the world, ending Google’s four years at the top of Millward Brown’s BrandZ global rankings, thanks to the launch of the iPad tablet computer and new versions of the iPhone and iMac.
