Shifting the UK communications infrastructure from electricity-hungry masts to solar-powered satellites would help meet carbon emission targets.

The use of space for phones, TV and broadband internet could be a realistic prospect within a few years, according to supplier group Intellect.

Communications use a considerable amount of power. Terrestrial TV broadcasts, for example, produce more than 250,000 tons of CO2 every year.

But a single satellite can provide all UK channels, in high-density format, with virtually no emissions, according to Intellect programme manager Emma Fryer.

“The concept is already a reality with some of the broadcast infrastructure, and cannot be far off when it comes to communications,” she said.

Launching satellites is increasingly efficient, and already uses less energy than one transatlantic flight. As a result, satellite services are moving from highly technical, often military, uses to a more consumer-oriented market. So far, 80 per cent of the UK’s burgeoning space market is concentrated in the media and communications sectors.

Sunshine-powered satellites also offer economic benefits. The UK leads the global market for both low-cost satellites and mobile satellite communications. And the space sector contributes £7bn to the economy annually and employs more than 70,000 people.
