It costs less than a pound to run an iPad for a year

An iPad uses 5% of the resources of a PC

Jonathan Fahey, for the Associated Press:

That coffee you're drinking while gazing at your iPad? It cost more than all the electricity needed to run those games, emails, videos and news stories for a year.

The annual cost to charge an iPad is just $1.36, according to the Electric Power Research Institute, a non-profit research and development group funded by electric utilities.

By comparison, a 60-watt compact fluorescent bulb costs $1.61, a desktop PC adds up to $28.21 and a refrigerator runs you $65.72.

$1.36 is just 88p. It's actually quite a lot more expensive than that to run an iPad in the UK, though, since electricity here is almost twice as expensive (13.7p as opposed to 7.4p per kilowatt hour). Even so, the key point stands up: the cost of running an iPad for a year is less than 5 per cent of the cost of running a desktop PC for a year.

They may not feel like it yet, but tablets are the future of computing. Just as laptop PCs have eaten away at the market share of desktops, so the same thing will happen with tablets and laptops.

And this, fundamentally, is the flaw in arguments that there must be limits to growth. It's an idea that has celebrated its 40th birthday this year: that economic growth requires continuous consumption of resources, which will eventually overshoot the carrying capacity of the earth. A recent publication by the New Economics Foundation restates it:

[I]ndefinite global economic growth is unsustainable. Just as the laws of thermodynamics constrain the maximum efficiency of a heat engine, economic growth is constrained by the finite nature of our planet’s natural resources (biocapacity). As economist Herman Daly once commented, he would accept the possibility of infinite growth in the economy on the day that one of his economist colleagues could demonstrate that Earth itself could grow at a commensurate rate.

Yet this little bit of news shows that to be false - or at the very least, not as self-evidently true as it seems. No-one can deny that moving from one desktop PC to 20 iPads feels a bit like some growth has happened; and yet it requires fewer, not more, resources.

Good news, everyone! Things might carry on getting better. That would be nice.

Charging for just under two pounds.

Is there such a thing as responsible betting?

Punters are encouraged to bet responsibly. What a laugh that is. It’s like encouraging drunks to get drunk responsibly, to crash our cars responsibly, murder each other responsibly.

I try not to watch the commercials between matches, or the studio discussions, or anything really, before or after, except for the match itself. And yet there is one person I never manage to escape properly – Ray Winstone. His cracked face, his mesmerising voice, his endlessly repeated spiel follow me across the room as I escape for the lav, the kitchen, the drinks cupboard.

I’m not sure which betting company he is shouting about, there are just so many of them, offering incredible odds and supposedly free bets. In the past six years, since the laws changed, TV betting adverts have increased by 600 per cent, all offering amazingly simple ways to lose money with just one tap on a smartphone.

The one I hate is the ad for BetVictor. The man who has been fronting it, appearing at windows or on roofs, who I assume is Victor, is just so slimy and horrible.

Betting firms are the ultimate football parasites, second in wealth only to kit manufacturers. They have perfected the capitalist’s art of using OPM (Other People’s Money). They’re not directly involved in football – say, in training or managing – yet they make millions off the back of its popularity. Many of the firms are based offshore in Gibraltar.

Football betting is not new. In the Fifties, my job every week at five o’clock was to sit beside my father’s bed, where he lay paralysed with MS, and write down the football results as they were read out on Sports Report. I had not to breathe, make silly remarks or guess the score. By the inflection in the announcer’s voice you could tell if it was an away win.

Earlier in the week I had filled in his Treble Chance on the Littlewoods pools. The “treble” part was because you had three chances: three points if the game you picked was a score draw, two for a goalless draw and one point for a home or away win. You chose eight games and had to reach 24 points, or as near as possible, then you were in the money.

“Not a damn sausage,” my father would say every week, once I’d marked and handed him back his predictions. He never did win a sausage.

Football pools began in the 1920s, the main ones being Littlewoods and Vernons, both based in Liverpool. They gave employment to thousands of bright young women who checked the results and sang in company choirs in their spare time. Each firm spent millions on advertising. In 1935, Littlewoods flew an aeroplane over London with a banner saying: Littlewoods Above All!

Postwar, they blossomed again, taking in £50m a year. The nation stopped at five on a Saturday to hear the scores, whether they were interested in football or not, hoping to get rich. BBC Sports Report began in 1948 with John Webster reading the results. James Alexander Gordon took over in 1974 – a voice soon familiar throughout the land.

These past few decades, football pools have been left behind, old-fashioned, low-tech, replaced by online betting using smartphones. The betting industry has totally rebooted itself. You can bet while the match is still on, trying to predict who will get the next goal, the next corner, the next throw-in. I made the last one up, but in theory you can bet instantly, on anything, at any time.

The soft sell is interesting. With the old football pools, we knew it was a remote flutter, hoping to make some money. Today the ads imply that betting on football somehow enhances the experience, adds to the enjoyment, involves you in the game itself, hence they show lads all together, drinking and laughing and putting on bets.

At the same time, punters are encouraged to do it responsibly. What a laugh that is. It’s like encouraging drunks to get drunk responsibly, to crash our cars responsibly, murder each other responsibly. Responsibly and respect are now two of the most meaningless words in the football language. People have been gambling, in some form, since the beginning, watching two raindrops drip down inside the cave, lying around in Roman bathhouses playing games. All they’ve done is to change the technology. You have to respect that.
