100 Watts

Having replaced all the bulbs in my study with energy savers about 1.5 years ago. My eyesight definitely got worse since doing that. They just don't give off as much light - despite what anybody says. And trying to work with sub-optimal lighting is bad for your eyesight.

The EU has banned normal light bulbs. It will be interesting see a statistical correlation between the restriction of supply of normal light bulbs and a rise in worsening eyesight of the general populace.

You must know something opticians don't then.

And physicists.

14p a unit is way too much to be paying for daytime electricity unless you're on an E7 tariff with a low nightime rate to offset it. You could get a much better deal , try the comparison sites.

Hi ron3003,

that's what it costs for 100% renewable energy (wind farm) . . . I think your talking about nuclear or fossile fuel generated power right?

 

[Energize]

Wow 14p is more than twice as much as we pay, go nuclear!

 

[Big.Wayne]

go nuclear!

Hey Energize,

well from a cashflow point of view yeah I can see the appeal of slashing my kWh costs from 0.14p to 0.06p but there is something about nuclear power that gives me the willies! . . . and bearing in mind that mankinds energy demands are steadily growing I don't think building more and more nuclear power plants is really the way forward? . . .

Apparently there is an abundance of 100% renewable energy from Wind/Wave/Tidal/GeoThermal/Biomass/Solar sources to meet all our energy needs so I'm not quite sure why we don't tap some of that instead?

Anything that isn't "renewable" will surely run out at some point? . . i.e it's finite . . . going the non renewable path would surely lead to all the coal being used up and nuclear power plants on every street corner no?

There's enough uranium to last longer than the earth, so running out isn't a problem.

No more than going renewable results in wind farms on every roof. For any given land area a nuclear power station produces far more energy than any other source.

Switch to daylight bulbs for the study (as I've done). It makes a huge difference (even at the same wattage). Normal bulbs are fine everywhere else, but you're right - a study needs good work lighting and that's daylight bulbs. I'd rate them higher even than standard incandescent bulbs.

And trying to work with sub-optimal lighting is bad for your eyesight.

I'm not aware of any evidence for that. Eye fatigue, certainly, but last I heard (on good authority) there is little or no evidence that you can wear your eyes out by using (or even over-using) them. Same applies to watching TV in a dark room, etc.

Which is no use when this land is unable to sustain human life due to the damage it's doing to the environment!

 

[Energize]

No need to worry then because it doesn't damage the environment. Nuclear produces the least CO2 of any power station overall.

Care to expand on that?

It does, not massively, but you still get leaks etc. Quite a few part radioactive beaches around the UK, and waters. And nuclear dumps etc. Decommissioning of crap in our waters etc There is potential for risk, that's the problem with some people.

It isn't a great thing to be having about in all honesty. Not for me.

 

[Big.Wayne]

Hey Energize,

There's enough uranium to last longer than the earth, so running out isn't a problem.

I think you misunderstood what I meant . . . if Fossil fuel is a finite power source it will run out right?

And what is the by-product of nuclear powerstations? . . . isn't there some Radioactive waste produced that can only be dealt with by:

• concentrate-and-contain
• dilute-and-disperse
• delay-and-decay

finite methods or?

No more than going renewable results in wind farms on every roof

and Wave/Tidal/GeoThermal/Biomass/Solar?

 

[Energize]

Hey Energize,

No I don't think I misunderstood. Uranium isn't a fossil fuel btw.

There is always a potential for accidents if things are not maintained properly, just as there are with any other power plant, like the huge explosions at fossil fuel plants.

 

[Biohazard]

No I don't think I misunderstood. Uranium isn't a fossil fuel btw.

No it isn't.

But Uranium and fossil fuels are both non-renewable so will be exhausted eventually.

 

[Energize]

No it isn't.

But Uranium and fossil fuels are both non-renewable so will be exhausted eventually.

Earth will be uninhabitable before uranium runs out though so it's a non-issue.

 

[Monkeynut]

No it isn't.

But Uranium and fossil fuels are both non-renewable so will be exhausted eventually.

So will the sun's own fuel, what's your point?

 

[Biohazard]

So will the sun's own fuel, what's your point?

Not much about the sun that's for sure.

Its a dirty technology, it isn't clean. That is a myth. Yes, technology might get to the point where keeping up with supply demand is removed, it still doesn't make it risk or waste free.

Your focussing on the uranium which isn't the complete nuclear picture is it?. . . my question is about the hazardous radioactive by-product and the method of its disposal?

What about it?

Dangerous high level nuclear waste can be transmuted to isotopes with shorter half lives in the range of decades and many types of nuclear waste such as depleted uranium can be used in breeder reactors. Any remaining high level waste can be stored underground where it isn't a threat, it's even feasible to deliver it to the Earths mantle.

The vast majority of nuclear waste however is harmless low level waste.

 

[Big.Wayne]

go nuclear!

Hey Energize,

Sadly my personal knowledge is quite limited on this subject and I'm not sure if what you are telling me is based on a lot of knowledge you have built up over years of study and research or in fact whether or not you have just done a quick google in the past few minutes?

As I have my doubts and I'm unable to ascertain if what you are saying is truth or falsehood I think I'll probably keep paying 0.14p for Wind-power kWh/units instead of taking your word on it . . no offence intended!

The vast majority of nuclear waste however is harmless low level waste.
