Energy saving

I have just switched back to a naked 100W lightbulb - what a difference over the energy saving ones. Instant bright light - much better!!!

I am starting to wonder if you really save anything using an energy saving bulb. Britain doesn't have much of a summer so the rest of the time it's pretty cold. A normal lightbulb wastes most of it's energy as heat. Now that heat goes into your house and as most houses have thermostatically controlled heating then it obviously follows that the heating in the house will need to come on less often.

The same hold true for TVs and other household appliances. Well insulated houses often don't turn their heating on until October/November - I suspect they would have to turn them on sooner without the heat being giving off by electrical equipment.

That will be the energy saving bulbs that cost 100 times more than a cheap light bulb I take it.

Nice one CP
But which form of heating is more environmentally friendly - nasty power station generated electricity for your bulbs & TVs or a whiff of natural gas for your super-mega, energy efficient, tree-hugging condensing boiler?

Fluorescent lights save power compared to an old fashioned bulb once they are up and running. But starting them is very power intensive. That bit isn't mentioned on the green sights.
Where I work in an effort to be green all lights come on automatically. I work in very large rooms and once you enter a door loads of lights come on for a minimum of 30 seconds even if your just going to a locker just inside the door. Daft !! But no doubt someones got a nice job out of it and if the statistics are shown in a favourable light (No pun intended) then the figures look impressive.

Some of these people that harp on about green issues need to get a life rather than a degree that every one seems to get nowadays.

My boiler engineer told me that modern boilers are very efficient in converting gas to heat but they have serious reliability issues that more than outway the cost savings of buying new.

Its a bit like perpetual motion. You don't get anything for nothing. Only fools believe otherwise.

As I say to the kids. If your cold put a jumper on !!! And to the missus put two jumpers on and stop moaning.

Funny thing is you talk to the kids about energy issues and global warming and they just think your stupid.

Central heating is seriously unhealthy. It just drags you down !!!!

Which is more environmentally friendly - stupid electric Toyotas running on nasty power station generated electricity, or a V8 running on LPG

They have now worked out that bio diesel uses 70% more energy than you get out of it - that's not counting the damage being done to rainforests etc where they are chopping everything down to grow the damn stuff!!!

The mentalists have a lot to answer for!!!

Morrisons were flogging 100W equivalent "low energy" jobs for 38p a few weeks ago. The good thing is you can put a "100w" bulb where only a 60 would fear to go, so lots more light! (Ands these ones come on pretty sharpish to full brightness too)

As for the battery poeweredc cars, what about all the extra energy used to lug the batteries around and the ***t that is the fallout of making said batteries & the mining of the minerals & metals to make them from?

Now where did I leave those CP41s........
