Beaucoup de clubs atroces

Beaucoup de clubs atroces à Los Angeles. L’ambiance hype de mauvais gout me rappelle souvent les boites de station balnéaire en Méditérranée et le son est rarement au niveau, l’electro...

saya mungkin satu-satunya raja di kata kunci ini adalah ide yang baik

Anda dapat percaya atau tidak kalau Google suka membaca 'title' dari halaman Anda. Kombinasi judul yang Anda gunakan, kata kunci juga akan disimpan dan digunakan kemudian. Sekarang Anda harus memutuskan untuk mempelajari judul blog dengan kata kunci yang sesuai yang Anda targetkan. Jika kata kunci yang Anda menelusuri lebih populer maka kemungkinan untuk menjadi posisi teratas juga pasti lebih serius. Namun, jika posisi pencarian kata kunci Anda belum begitu baik, atau kata-kata baru, saya mungkin satu-satunya raja di kata kunci ini adalah ide yang baik Anda tidak membuat judul lebih dari 6 kata, lebih kata jika kata yang tersisa akan diabaikan dan mungkin kurang bermanfaat sebagai akibatnya.
Sebagai contoh 'Bagaimana meningkatkan peringkat Google bantuan Page dengan menggunakan perangkat lunak '. Jika artikel Anda dengan judul, kemudian disimpan hanya "Bagaimana meningkatkan peringkat Google Page" dan sisanya tidak akan Permalink. Dari membaca blog Google di sini dan Anda akan mempengaruhi posisi masa depan Anda Search Engine Peringkat PT. Dalam kasus yang berbeda Anda juga akan menemukan dampak yang signifikan mengubah, jika Anda mengubah judul judul blog anda, yang sudah ada. Jika Anda mengubah judul topik yang sudah ada, maka otomatis Permalink ada juga akan berubah. Hal ini akan mempengaruhi link dari tempat lain yang sudah ada.

eed Green Taxes - to make sure da

On the Rebound???

In December 2003 I wrote off my Ford Ka in a smallish prang. I replaced it with a Golf TDi, for two reasons:

a. I want to have the option of using biodiesel (but that's another story...).

b. It did 55mpg compared with the Ka's 40mpg.

Brilliant - cut my fuel consumption by 28% and saved £250 each year.


£250 is exactly the cost of a return flight from Newcastle to New York. Given my love of travel, this is a real option. If I take it, then I've just doubled the annual carbon emissions I had in the Ka.

This is called the "rebound effect". If we save money through efficiency, we can easily wipe out the eco-benefits by choosing to buy or do something even more environmentally damaging with the windfall.

This is why we need Green Taxes - to make sure damaging practices are expensive. Airlines don't pay any tax on fuel, so flying is an extremely cheap way to damage the planet (and I've got previous). Getting expensive haircuts with my cash would be a much better option, but isn't really my thing (see profile pic).

The choice is ours.

weaker on is practical action. A series of sug

Al Gore: One Man and his Powerpoint

I went to see 'An Inconvenient Truth' last night.

The film consists of clips of Gore's famous presentation on climate change interspersed with flashbacks to ex-next-president's life, from his farm upbringing to the hanging chads in 2000. The former sections are powerful, persuasive and chilling, the latter sentimental, going on mawkish. These bothered me, but just as I was beginning to believe that the whole thing was the longest party political broadcast in history, the two strands collided. Gore's father grew tobacco on his farm and continued to do so despite the 60s & 70s furore over the link with cancer. Then Gore's sister Nancy died of lung cancer. Al Gore Snr stopped growing the crop overnight.

The moral: sometimes we need to be shocked into action.

The presentation parts were very slick. Animations showed what the impact of global warming will be on the world's major cities and films showed ice sheets melting. Occasional cartoons lifted the mood while still pushing the point.

Gore demonstrated clearly that the 'natural cycles' argument is a myth - carbon dioxide has never hit its current concentration in the 650 000 years we can analyse using ice cores. The 'lack of scientific agreement' myth was punctured as well - a survey of peer reviewed papers on the subject found 0% doubting manmade climate change.

What the film is weaker on is practical action. A series of suggestions flashed up over the end credits, but that was that. Gore seems to be working on this and I'll post a small vid later.

The verdict: Even if you think you've seen it all before, Do Not Miss This Film.

You can get CFLs in all shapes and sizes

Strike a Light

Today I was at a Carbon Trust training session on energy management. It was fairly heavy stuff on power factor correction and other dark arts, but to lighten the load the trainer did a quick demo of domestic lighting. It was good stuff - all proven with a meter - so I thought I’d pass his wisdom on.

- The little red neon lights on extension cords might only use a tiny trickle of electricity, but if we all left two of them on constantly each, their total energy use in the UK comes to the output of a medium sized power station.

- A good quality instant-start compact fluorescent lamp (CFL) will cost you £21 over its five year lifetime compared to £82 for a standard tungsten lightbulb. Don't bother with cheap IKEA CFLs tho.

- You can get CFLs in all shapes and sizes including a new compact 7 Watt model which will replace those greedy little 50 Watt halogen lights that everyone is filling their homes with.

- A fluorescent strip light uses less electricity starting up than it does at full brightness – nailing that myth about how it is better to leave them on all day than switch them off when you're not using them.

- Most old-fashioned lights (including outdoor security lights) can be replaced with newer models that consume less than a third of the energy.


target of cutting

he British government must curb the huge expansion in air travel or risk overshooting its self-imposed target of cutting carbon dioxide emissions by 60 percent by 2050, a study said on Tuesday.

CO2 emissions from aviation in Britain are set to surge by between four and ten times 1990 levels by the middle of the century, accounting on their own for two-thirds of the government's emission target for that year, it said. Yet far from doing anything about the problem, government policy is actively promoting airport expansion which could see passenger numbers more than double to 470 million a year, from 200 million, by 2030, it said.

"The government has to confront the contradictions in its policies," said Brenda Boardman from Oxford University's Environment Change Institute which conducted the study for the government-funded UK Energy Research Centre. "Unless the rate of growth in flights is curbed, the UK cannot fulfil its commitments on climate change. It has to undertake demand management. Relying on technological fixes alone is totally unrealistic," she said.

interested in the business

If you're interested in the business side of things...

I hope to have a Green Business Blog up and running in a couple of months to complement this one. In the meantime, you can read my views on the opportunities for businesses in the environmental sector at Management Issues. This is the first in a series of pieces on this theme.

current, voltage or wattage

current, voltage or wattage drawn by any device with a plug and costs £28. This is great for measuring the difference between the energy consumed when an appliance is 'on', when it's on 'standby' and the leakage into adaptors. Unfortunately it has an irritating design flaw - the screen gets obscured by the appliance's power cord and often requires a torch to read anyway.

The second is a meter which measures a house's total energy consumption. It consists of a sensor which clips around the live wire and plugs into a transmitter (bottom left in the pic). The display unit (bottom right) is wireless so you can put it anywhere in the house or carry it around as you try to find where all that energy is leaking. This cost about £80.

Expect a rash of posts relating to energy consumption in coming

Ground Source Heat Grump

Ground Source Heat Grump

In today's  observ repeats the old chesnut about Ground Source Heat Pumps producing 3-4 units of energy for every unit that is put in.

What she doesn't say is it takes 1 unit of electricity to get 3 units of heat. To get 1 unit of electricity you need to burn 3 units of gas in a power station. A modern condenser boiler is 90% efficient, so you'd get 2.7 units of heat if you just burnt the gas directly. On top of this I've been told that GSHPs struggle in practice to deliver 2.5 units of heat (1 of which is waste heat from the electricity running the pump's motor). Then the gas boiler wins.

"Ah, but you could use renewable energy!" say the Heat Pump acolytes. Yes, but who has too much renewable electricity? You'd be much better off using that electricity to power IT, lights and all the other stuff that can't run on lower forms of energy.

I've got a willing student doing an engineering project to look at the whole energy balance of Heat Pumps. I've challenged him to prove to me that they are a good idea. I'll keep you posted on how he gets on.

quarter of an hour each of DVD a

If I say that in an average day, the TV is on about 3 hours, of which half an hour is cable TV, and a quarter of an hour each of DVD and video, then the energy required is 0.2 units per day.

If, as above, I have the unused equipment on standby when watching TV, but switch everything off outside my 3 hours of viewing, I'll use 0.34 units - 41% of which is wasted. As a result I'm going to change the way our equipment is connected to the socket, so it is easier to watch terrestrial TV with everything else switched off.

Of course, if I leave it all on standby 24 hours a day, I'll use 1.49 units, a whopping 87% of which is wasted.

These are all piddling amounts of energy, but if you start to multiply up against 60 million people over a year, then it starts to get very significant indeed.
