Taking a longer-term view, a widely cited 2005 study by researchers at Stanford University projected that wind, if fully harnessed worldwide, could theoretically meet the world's present energy needs five times over. And a 2010 study by the National Renewable Energy Laboratory found that the United States could get more than 12 times its current electricity consumption from

wind alone. But impressive as these figures may sound, wind power still has a long way to go before it becomes a significant factor in reducing carbon emissions.
The potential is there — with abundant wind available for harvesting both on land and, especially, over the oceans — but harnessing that power efficiently will require enormous investments in manufacturing and installation.So far, installed wind power has the capacity to generate only about 0.2
terawatts (trillions of watts) of energy worldwide — a number that pales in comparison to an average world demand of 14 terawatts, expected to double by 2050. The World Wind

Energy Association now projects global wind-power capacity of 1.9 terawatts by 2020.
But that's peak capacity, and even in the best locations the wind doesn't blow all the time. In

fact, the world's wind farms operate at an average capacity factor (the percentage of their maximum power that is actually delivered) somewhere between 20 and 40 percent, depending on their location and the technology.Some analysts are also concerned that widespread deployment of wind power, with its inherently unpredictable swings in output, could stress power grids, forcing the repeated startup and shutdown of other generators to compensate for wind's variability.
Many of the best wind-harvesting sites are far from the areas that most need the power, necessitating significant investment in delivery infrastructure — but building wind farms closer to population centers is controversial because many people object to their appearance and their sounds.One potential solution to these problems lies offshore. While many wind installations in Europe have been built within a few miles of shore, in shallow water, there is much greater potential more than 20 miles offshore, where winds blow faster and more reliably.
Such sites, while still relatively close to consumers, are generally far enough away to be out of sight.MIT's Sclavounos has been working on the design of wind turbines for installation far offshore, using floating platforms based on technology used in offshore oilrigs. Such installations along the Eastern Seaboard of the United States could theoretically provide most of the electricity needed for the eastern half of the country.
And a study in California showed that platforms off the coast there could provide more than two-thirds of the state's electricity.Such floating platforms will be essential if wind is to become a major contributor to reducing global greenhouse gas emissions, says research engineer Stephen Connors, director of the Analysis Group for Regional Energy Alternatives (AGREA) at the MIT Energy Initiative.
Wind energy is "never going to get big if you're limited to relatively shallow, relatively close [offshore] sites," he says. "If you're going to have a large impact, you really need floating structures."All
of the technology needed to install hundreds of floating wind turbines is well established, both from existing near-shore wind farms and from offshore drilling installations.
All that's needed is to put the pieces together in a way that works economically.
But deciding just how to do so is no trivial matter. Sclavounos and his students have been working to optimize designs, using computer simulations to test different combinations of platforms and mooring systems to see how they stand up to wind and waves — as well as how efficiently they can be assembled, transported and installed. One thing is clear: "It won't be one design for all sites," Sclavounos says.In principle, floating structures should be much more economical than wind farms mounted on the seafloor, as in Europe, which require costly construction and assembly. By contrast, the floating platforms could be fully assembled at an onshore facility, then towed into position and anchored.
What's more, the wind is much steadier far offshore: Whereas a really good land-based site can provide a 35 forex-growth-bot factor, an offshore site can yield 45 percent — greatly improving the cost-effectiveness per unit.There are also concerns about the effects of adding a large amount of intermittent energy production to the national supply. Ron Prinn, director of MIT's Joint Center for the Science and Policy of Global Change, says, "At large scale, there are issues regarding reliability of renewable but intermittent energy sources like wind that will require adding the costs of backup generation or energy storage."Exactly
how big is offshore wind power's potential? Nobody really knows for sure, since there's insufficient data on the strength and variability of offshore winds. "You need to know where and when it's windy — hour to hour, day to day, season to season and year to year," Connors says. While such data has been collected on

land, there is much less information for points offshore. "It's a wholly answerable question, but you can't do it by just brainstorming."And the answers might not be what wind

power's advocates want to hear.
Some analysts raise questions about how much difference wind power can make. MIT physicist Robert Jaffe says that wind is "excellent in certain niche locations, but overall it's too diffuse" — that is, too thinly spread out over the planet — to be the major greenhouse gas-curbing technology. "In the long term, solar is the best option" to be sufficiently scaled up to make a big difference, says Jaffe, the Otto (1939) and Jane Morningstar Professor of Physics.
Connors is confident that wind also has a role to play.
"This planet is mostly ocean," he says, "and it's pretty windy out there."Tomorrow: Vast amounts of solar energy radiate to the Earth constantly, but tapping that energy cost-effectively remains a challenge.
The latest news

and best bets in our daily horse racing blog, plus day three of our weekly tipping competitionWednesday's best betsThe Cheltenham Festival has come and gone and remarkably seems to get more popular with each passing jumps season.
The Duke and Duchess of Cambridge turned up on Gold Cup day where they were spotted horsing around (geddit) as you can see from this coverage of their visit.
One wonders if William is going to show more of an interest in the sport than his father and it appears he is being encouraged to do so. Only this morning Ascot revealed via Twitter that "the Windsor Forest Stakes at the Royal

Meeting has been renamed The Duke of Cambridge Stakes."The Racing UK channel ran a full replay of the meeting last Sunday and it was rewarding to sit down and take a look at the races again with an eye to the future. There were some

obviously

brilliant performances – hello Sprinter Sacre and Our Conor – but I was looking for

some less obvious examples of horses to follow who might be decent odds in the future.It's a pity that Rival D'Estruval is to be denied a chance at the Scottish National at Ayr next month as he looked an ideal candidate for that event following his unfortunate tumble in the National Hunt Chase at the Festival.Trainer Pauline Robson's partner and assistant, David Parker, said: "[Rival D'Estruval's] absolutely fine.
He wasn't even sore, really.
He's been ridden out for the last couple of days and is in good form.
He won't run in the Scottish National.
We think it would be too much to ask him to run in two four-mile races so close together.
If he's in good form he could still go to Ayr as there is a three-mile novice handicap he's eligible for.

Historically horses who have run well in the four-miler at Cheltenham have disappointed in the Scottish National and he was trained quite hard for the Cheltenham race."The
gelding had every chance when tipping up two out last week and seems sure to go well in long-distance chases.The other one that caught my eye with an eye on future handicaps in mind was Ifandbutwhynot who appeared to have a good chance in the County Hurdle but didn't get the best of trips and came home well down the field.He
made his move wide of the field and probably lost a fair bit of ground in the process but had looked useful in two victories this campaign and

is another worth noting. The Venetia Williams stable have had an excellent season and recorded a Cheltenham Festival winner last week at a meeting dominated by the top yards.
The trainer could add to her winter successes at Warwick today with Lone fat burning furnace in the opening event.The selection was a decent individual in France on the Flat and was a promising third at Wincanton last time out. Midnight Belle (4.35)
is worth backing to regain winning ways later in the afternoon at the meeting while at Haydock, Zaru (2.10) has an obvious chance for compensation after tipping up when in with a winning chance on his most recent appearance.Tipping competition, day threeSportingchad missed out Monday but was first to post yesterday and proved you don't need lots of form study, as he instantly found Brunnettes'only (12-1), Divertimenti (6-1) and All The Winds (5-2).

one you see for hours. • Somerset 358-6 v WarwickshireIt was green below and grey above but Marcus Trescothick, after a bit of agonising, chose to bat and at the end of the day he was happy with his decision. Somerset finished well placed and Alviro Petersen had hit his second century in three innings – in the other knock he hit a paltry 91.At
Essex in 2012 Petersen averaged 21; it looks as if he may surpass that this time. For some reason overseas batsmen like Taunton. When he was superbly caught at second slip by Rikki Clarke for 136, his tally for the season had reached 394.Somerset were faltering at 143 for four but for the second time this term Petersen found an accomplished ally in Jos Buttler.
He contributed a calm, cultured and unbeaten 90 in front of Ashley Giles, England's one-day coach, who was perched on top of the old pavilion for much of the day alongside his successor at Warwickshire, Dougie Brown.Buttler
caressed the ball around Taunton.
There were no reverse hits or scoops, only orthodox cricket strokes as he cruised along in Petersen's wake.
Giles was delighted by Buttler's innings.Despite the verdant pitch and threatening clouds shrouding the Quantocks early on, Trescothick and Nick Compton

compiled a century partnership.
They needed some luck and a lot of skill. Chris Woakes bowled some

fine deliveries; Clarke felled Trescothick with a bouncer.
However, it was Jeetan Patel, the off-spinner, who broke the partnership just before lunch.Trescothick
is rightly revered as a player of spin bowling, but at The Oval last week and at Taunton on Thursday he was lbw to the first off-break he received. This is a mystery that he will solve, but even he will have a few jitters when he faces up to his next off-break.Compton batted with assurance and departed with dignity in the over after Trescothick's dismissal. This match is televised and

it was soon evident that Compton had nicked the ball from Clarke, to which he was given lbw.
He headed off without too much fuss.Neither James Hildreth, caught at square-leg off a surprise bouncer from Woakes, nor Craig Kieswetter, vainly seeking a first run from his 17th ball, could bed

in. But Buttler could alongside Petersen in a 193-run partnership. The Warwickshire attack was hampered by the fact that the radar of their newcomer, Oliver Hannon-Dalby, was faulty. He kept bowling at Petersen's leg-stump, which, as county bowlers are discovering, is a bad idea.County Championship 2013 Division OneCounty Championship Division OneSomersetWarwickshireCricketVic Marksguardian.co.uk © 2013 Guardian News and Media Limited or its affiliated companies.

Guidebooks are a relic of a bygone age that have little to do with travel nowThe sale of Lonely Planet at a knock-down price by the BBC is being passed off as business restructuring, but the alternative view is that the guidebook is finished – I mean as a paper brick that you drag around India and finally wipe your bum on in Goa, not as a digital item. Guidebooks may survive in their digital incarnation, but even then I have my doubts.
The whole format

of the modern backpacker guidebook has been looking pretty decrepit for a while, a relic of a bygone age before google sniper download sites and the blogosphere, among other things, served up all that information on your phone, and up to date too.I can't say I will mourn their passing for very long. Still, there have been some wonderful moments. Back in the 1980s, Bill Dalton's guide to Indonesia, published by Moon, was something of a classic: a huge tome that could spin out any number of evenings in a hammock as you plotted complex sea journeys to remote atolls where only Stone Age tribes were said to live. Lonely Planet's Africa on a Shoestring by Geoff Crowther was my companion on my first trip and so holds a special place in my heart. Written by a veteran of the hippy trail, the book's cultural context was of travellers who saw themselves more as wandering hobos and no one ever said the dread words, "I'll be back in a year".
The romantic ideal was that you might never come back.When I leaf

through that book now, what I see is gaps, not gap years. Entire regions that have little or no information. Whole mountain ranges that get a few lines or less. That was the thing about those earlier books: there was plenty they didn't know.
You filled in the holes with your imagination and maybe later with your own experience. There was just sufficient to inspire interest and also reveal that precious few people had bothered to visit, if anyone. I can remember setting off into the mountains of northern Darfur precisely because Geoff had furnished me with just a few tantalising snatches of information.Thirty years on and the guidebook has a comprehensiveness that can kill any sense of personal exploration.

It wasn't Lonely Planet's fault, but all those backpacker feet ended up creating modern trade routes right across the world, and in those routes was little room for innovation and initiative.
The locals who thrived on a recommendation in a guidebook did well for a while. Some have become comprehensive dealers in onward transport, local tours, and banana pancakes. Others have cashed in, relaxed, lost their edge and often discovered that it doesn't matter: the legions of eager westerners keep on coming.Several
times on recent expeditions I've found that I returned home to find I hadn't opened the guidebook at all, except to read the brief overview of history which I could have got elsewhere and in much more detail. The maps, once essential, have been bettered by Google Earth or others; the top sights are a list of overcrowded, overpriced attractions besieged by tour group coaches; the photos always did seem irrelevant.So what might be the side effects of guidebook death? Travellers still need information and digital technology can

provide all that very easily. The urge to get out beyond the limits of knowledge is still there, it always was.
Back in 1982, arriving dust-covered and hungry in Khartoum, I remember seeing a long-haired American outside the post office with a cloth on the ground covered in pieces of paper torn from a school exercise book. On them were written poems that he was selling to fuel his further travels, and next to them, also up for grabs, was a well-thumbed copy of Geoff's book.I was both shocked and impressed. Selling the guidebook seemed like the last act before becoming a true traveller, a person who relied on word-of-mouth and serendipity.
It was an act of bravery that I could not hope to emulate. Of course the poet might still be there, but more likely is that he made his own great journey, one like nobody else's. In the future, perhaps, we will see a young traveller outside the internet cafe and on the ground a piece of cloth with a few poems for sale, and next to them, a phone.Travel
