I've been meaning to write about these videos for some time but somehow it never seemed the right moment (and all our Woolworths work kept getting in the way), so apologies if you've already seen them elsewhere. Yet in the lull after the hard launch of our light bulbs campaign, it's worth pointing out that it's not just in the UK that a shift to energy-efficient bulbs is being sought.

I was just about to write a piece slating Woolworths (as, after all the fuss we caused on Saturday, we still hadn't heard from them) when I got a call from Laura, one of our campaigners, to say she had a letter from them explaining what they're going to do about energy-guzzling light bulbs. I'm looking at it now and I'm sorry, but I'm still going to slate them.

It's from CEO Trevor Bish-Jones who begins by not asking for us not to stage in-store protests in future but to communicate directly with himself. So he'll be pleased about all the emails he's been getting from you (if you haven't emailed him, do it now, or you can call your local branch of Woolies and speak to the manager).

He goes on to use some well-worn arguments which I thought it would be useful to air here. Take it away, Trevor.

It's just after 3pm now and all of the main teams of volunteers have either been removed from or left their respective branches of Woolworths after clearing the shelves of inefficient light bulbs. The management at head office seems clearly rattled as their press officers have been telling our Light Brigaders (or is that Brigadiers?) that there'll be an emergency meeting on Monday to discuss their light bulb policy. We'll keep you posted on what, if anything, transpires next week. In the meantime, there's our cheap-as-chips video and photos from the day of action on Flickr to keep you entertained.

With 2 billion pairs of eyes expected to be firmly clamped on the Live Earth concerts tomorrow, the word about climate change will be spread far and wide. Although, as George Marshall argues, perhaps enough people already know and they're just waiting to be forced into doing something about it through new laws introduced by their government.

We don't have to wait, though - in fact, we can't wait. Even the most optimistic predictions about the effects of climate change say that we need to take immediate action. So if watching Madonna cavorting around has spurred you on, what can you do here and now? Funny you should ask...
