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.

Where Labour has no chance, hold your nose and vote Lib Dem

May's gamble, MacKenzie's obsession and Wisden obituaries - Peter Wilby's First Thoughts.

In 2007 Gordon Brown allowed rumours to circulate that he would call an early general election for the spring of 2008. When he failed to do so, he was considered a coward and a ditherer and never recovered. Theresa May has tried a different strategy. After firmly denying that she would call an early election and killing off speculation about one, she suddenly announced an election after all. Will this work better for her than the opposite worked for Brown?

The Prime Minister risks being seen as a liar and an opportunist. Her demand for “unity” at Westminster is alarming, because it suggests that there is no role for opposition parties on the most important issue of the day. If Labour and the Lib Dems are smart enough to co-operate sufficiently to rally the country against what looks like an attempt to instal an authoritarian, right-wing Tory regime, May, even if she wins the election, could find herself weakened, not strengthened. I never thought I would write this but, in constituencies where Labour has no chance, its supporters should hold their noses and vote Lib Dem.

Taken for granted

I wonder if May, before she took her decision, looked at the precedents of prime ministers who called unnecessary elections when they already had comfortable parliamentary majorities. In 1974, after three and a half years in office, Edward Heath, with a Tory majority of 30, called a “Who runs Britain?” election during a prolonged dispute with the miners. He lost. In 1923, Stanley Baldwin, a new Tory leader sitting on a majority of 75 obtained by his predecessor just a year earlier, called an election because he wished to introduce tariffs, an issue strikingly similar to the one raised by Brexit. He also lost. The lesson, I think (and hope), is that prime ministers take the electorate for granted at their peril.

China’s long game

Commentators compare the crisis ­involving North Korea and the US with the Cuban missile crisis of 1962. It doesn’t feel that way to me. For several days that year, nuclear war seemed, to my 17-year-old mind, all but inevitable. I went to the cinema one afternoon and felt surprise when I emerged three hours later to find the world – or, at least, the city of Leicester – going about its business as normal. Two nuclear powers were in direct confrontation. The US threatened to invade communist Cuba to remove Soviet missiles and blockaded the island to prevent deliveries of more weapons. Soviet ships sailed towards the US navy. It wasn’t easy to imagine a compromise, or who would broker one. Nobody doubted that the two sides’ weapons would work. The Soviet Union had carried out nearly 200 nuclear tests. North Korea has claimed just five.

For all the talk of intercontinental missiles, North Korea at present isn’t a credible threat to anybody except possibly its neighbours, and certainly not to the US or Britain. It is in no sense a geopolitical or economic rival to the US. Donald Trump, who, like everybody else, finds the Middle East infernally complicated, is looking for an easy, short-term victory. The Chinese will probably arrange one for him. With 3,500 years of civilisation behind them, they are accustomed to playing the long game.

Mussel pains

Whenever I read Kelvin MacKenzie’s columns in the Sun, I find him complaining about the size of mussels served by the Loch Fyne chain, a subject on which he happens to be right, though one wonders why he doesn’t just order something else. Otherwise, he writes badly and unfunnily, often aiming abuse at vulnerable people such as benefit claimants. It’s a new departure, however, to insult someone because they were on the receiving end of what MacKenzie calls “a nasty right-hander”, apparently unprovoked, in a Liverpool nightclub. He called the victim, the Everton and England footballer Ross Barkley, who has a Nigerian grandfather, “one of our dimmest footballers” and likened him to “a gorilla at the zoo”.
The paper has suspended MacKenzie, a former Sun editor, and Merseyside Police is investigating him for racism, though he claims he didn’t know of Barkley’s ancestry.

Several commentators express amazement that Sun editors allowed such tripe to be published. It was not, I think, a mistake. Britain has no equivalent of America’s successful alt-right Breitbart website, disruptively flinging insults at all and sundry and testing the boundaries of what it calls “political correctness”, because our alt right is already established in the Sun, Express and Mail. To defend their position, those papers will continue to be as nasty as it takes.

Over and out

Easter is the time to read the cricket annual Wisden and, as usual, I turn first to the obituaries. Unlike newspaper obituaries, they record failures as well as successes – those who managed just a few undistinguished performances in first-class cricket and, most poignantly, some who promised much but died early. We learn of a 22-year-old Indian who, during demonstrations against the alleged molestation of a schoolgirl, was shot dead by police and whose grieving mother (invoking the name of one of India’s greatest batsmen) cried, “Bring my Gavaskar back!” In England, two young men drowned, having played one first-class match each, and a 22-year-old Sussex fast bowler, described as “roguish” and “enormously popular”, fell off a roof while celebrating New Year with friends in Scotland. In South Africa, a young batsman was among five municipal employees killed when their truck crashed; the local mayor fled the funeral as his workmates “chanted menacingly” about unpaid wages.

Among the better-known deaths is that of Martin Crowe, probably New Zealand’s best batsman. In a Test match, he once got out on 299 and reckoned the near-miss contributed to the cancer that killed him at 53. “It tore at me like a vulture pecking dead flesh,” he said. Cricket can do that kind of thing to you.
