Another day, another carbon-cutting solar project along the River Thames.

Towering over Westminster Bridge — just around the bend from the solar panel-topped Blackfriars Railway Bridge — is the most landmark-y of all London landmarks: The Clock Tower, aka Elizabeth Tower, aka Big Ben.

And Big Ben — technically, it’s the nickname for the great bell of the iconic, four-faced chiming clock and not the completed-in-1859 clock tower itself, although most tourists folks refer to the entire structure as Big Ben — just might be the latest London landmark to be treated to an energy-efficient upgrade via the installation of photovoltaic panels (in this instance, they’d be installed on the clock face).

The idea, currently being considered by the House of Commons, is viewed as just one method in which Parliament can improve energy efficiency by 34 percent by the year 2020. I’d be curious as to how much juice is actually required to keep that bad boy lit up and ticking and how much slapping on solar panels would save.

While the Big Ben-goes-solar scheme is far from a sure thing at this point — “These ideas will now be discussed, reviewed and prioritised by the Environment Team with a programme of initiatives to be developed in future months,” a House spokesperson elaborates to The Guardian — there are a slew of other energy-saving initiatives that will be going forward including the re-insulation of sections of the Palace of Westminster’s roof with sheep’s wool insulation and the installation of solar panels on some of the flat roofs atop the House of Parliament.

But wait ... there’s more:

… the House is carrying out a number of other green measures this year, including installing voltage optimisation technology to reduce energy wastage, exploring energy efficiency improvements for all buildings, and replacing lights with low energy LEDs.

Will London's most visible timepiece get a solar facelift?
British Parliament is striving to reduce its carbon footprint through various efficiency measures, including potentially outfitting Big Ben with PV panels.
