The ROCA 3 CHP plant in Rotterdam provides electricty and heat to 400,000 homes

Due to popular demand (well, demand anyway), The Weekly Geek now has its very own RSS feed.

Back in 1882, Thomas Edison built the United States' first electric power plant. Pearl Street Station, which supplied the good folks of Lower Manhattan with electricity for lighting and steam for manufacturing, was around 50 per cent efficient.

125 years on, the typical UK power plant is just 38 per cent efficient. But those modern power plants that have been built on the same principles as Edison's are reaching efficiency levels of up to 95 per cent.

So how did Edison do it? And where are we going so wrong?

In this week's slightly tardy Weekly Geek, we're looking at combined heat and power (CHP): the system Edison was using, and the heart of any truly clean and efficient decentralised energy system. (Those who read the first Weekly Geek on decentralised energy may notice a fair bit of crossover.)

Following last week's direct action maelstrom at Heathrow and the Houses of Parliament, the media has been courting the people involved with features popping up all over the place about the so-called new generation of eco-activists.

A particularly interesting piece went out last night on Radio 4: Graham Thompson (described by the Evening Standard as the "daddy" of the parliament protest group) appeared on The Moral Maze to argue the case that civil disobedience is an acceptable part of protest in the democratic process. Listen again for the inevitable seven days.

Meanwhile on the Guardian's Environment Weekly podcast, our own climate campaigner Joss Garman was in the studio to talk about the 'new breed' of activist. Listen again for... well, forever probably.

But if I come across one more reference to Swampy...

One of the pleasures of working at Greenpeace is having access to a truly incredible photo library and there's been more than one occasion when, looking for images to accompany a blog story, I've become lost in the wealth of powerful and affecting images.

The photographers who supply us with these photos are rewarded for their work with the occasional trophy and Daniel Beltra, who has accompanied Greenpeace campaigners on expeditions all over the world, was last week presented with the Global Vision Award for photos he took in the Amazon as part of Pictures of the Year International. He also received an Award of Excellence in the Science/Nature category for a collection from the Antarctic, taken during last year's Southern Ocean expedition on the Esperanza.

Fashion is a fickle beast but now a whole city is going retro (well, not quite but it was too good a pun to waste). The long-awaited plan to retrofit all buildings owned and operated by the Greater London Authority (GLA) with energy-saving systems and technology is finally in motion with contracts awarded to companies which are going to slash the capital's emissions.

While much of the discussion about energy efficiency in buildings has focused on new houses, there are still millions of older buildings that lack proper insulation or top-notch heating systems. No matter how good those eco-towns are, if and when they're built they'll only represent a small proportion of the building stock in the UK. Fortunately, the GLA have a cunning plan.
