Screw the incandescent lightbulb
This technology is also available in GU10 format so my first experiment was placing 6 of them into the living room ceiling sockets. The models I purchased were from Megaman and are available in most DIY stores (in Belgium anyway). There's a 7 Watt and a 9 Watt model, I opted for the former with a colour temperature of 2700K (closest to the classic bulb).
The light is slightly whiter but only really noticeable if you compare it to a traditional halogen in the same room, the biggest difference is that the beam is wider, so you don't get the patterns on the wall that halogens often make. To be honest, the halogens that were there originally did give off a nicer light, but the difference is small enough compared to the positive environmental and financial impacts that we can happily live with it. The amount of light also seems equivalent to what the 50W halogens were outputting.
Next up was the small corridor between the bedroom and bathroom. As there wasn't a need for much light there, I decided to try something different and place downlighters made up of 21 blue leds each for a total power consumption of 2 Watts. I guess you could describe the light there as "blue moonlight". You can see where you're going but don't expect to read a book in there. We quite like it, especially when we have to walk through there bleary-eyed in the middle of the night. It might not work everywhere, but the walls are white and the design minimal so it all fits together quite well. I can't recall the brand I used, but you can find similar lamps in many DIY stores too.
The bathroom was the scene of yet another experiment: cold cathode lamps (CCFL). These are actually a little less efficient than compact fluorescents. Their lifetime, on the other hand, is 50.000 hours compared to the 15.000 of a CFL (or the 1000 of a traditional bulb) and they can be turned on and off for short periods of time which is often the case in a bathroom.
The ones I purchased advertise a power consumption of 5 Watts and a colour temperature of 2700K. Colour-wise, I'd say they're closer to 3500 or 4000K, the light is neon-white, fine for a bathroom, but I wouldn't want them anywhere else. As far as the amount of light goes, they're each equivalent to a 20 or 25 Watt halogen, perfect for taking a shower but make sure you have extra lighting over the mirror for shaving or applying makeup.
And, last but not least, the strangest of them all: the 1W Luxeon LED. The luxeon is one of the most powerful LEDs on the market, I have one in my bike light and normal LED lamps on other bikes look like their battery is about to run out when compared to it. And yes, it's also available in a GU10 fitting.
Obviously, you're not going to get a huge amount of light from one of these, they'll usually be found lighting up a painting or a sculpture, but I decided to try them in my office anyway. I just need a bit of background lighting when I'm using the computer so as not to work in complete darkness. If I need more light, I have a floor lamp with a CFL in it.
For that use, the luxeon does the job perfectly. The light is warm but feeble, just enough to find my way through all my rubbish to my chair or see what keys my fingers are typing on. This won't be everyone's cup of tea, but if you tend to hack through the night behind your monitor, they might just do the trick. I haven't seen them in many shops, but they're available in plenty of online stores.
There you go, I hope that helped someone out there. I admit some of it is early-adopter stuff, but someone's got to do it * cough*.

The Empty Tank (Jeremy Leggett)
Jeremy Leggett is a geologist who worked inside the big oil companies for years before jumping ship to Greenpeace and finally setting up his own renewable energy company. In this book, he lays out his arguments for an early peak in oil production combined with the ongoing climate crisis and their implications on our way of life. He doesn't paint a pretty picture but the facts are there and his insider knowledge tends to confirm the well-held beliefs that changes will not come from above. He sees future energy prices and lack of forward-thinking pushing us back into exploiting coal and other dirty fuels, thus accelerating climate and economic instability. It's not all gloom though, he sees renewable energy setting us back on track but only after crossing a very depressive post-cheap-oil era. Basically: we'll fall right down before we can stand up again. Worth the read if only for the insider oil stories. Note: this book is also sold under the title 'half gone'. [link]

An inconvenient truth
The climate is changing radically, affecting our future, and we are the cause. This is no longer debatable: the film shows how 100% of peer-reviewed academic papers support this fact while 53% of mainstream media stories express doubt, lobbies are powerful things. Al Gore puts the scientific facts into an eloquent, entertaining and clearly understandable narrative without ever getting overtly alarmist or bleak. According to Gore, we have 10 years to turn things around. In that case, this film should be mandatory viewing, especially if you have children. Hopefully, it won't just be preaching to the converted; if you're a doubter or have a friend who is, I dare you to see this and come out unaffected. [link]
