The Near Future
Biomass electric generators. These of course exist but I think in the near future we will see many popping up in urban areas to provide power for local communities. These run on any waste bio material, woodchips, straw, sawdust, peat and natural gas, the latest models use a sophisticated heat extraction and recovery system using insulated pipes to heat local building such as hospitals. The World's largest biomass power plant will soon open in Port Talbot and will provide enough power for half of Wales.
Part of the gas supplies needed for biomass generators will be supplied by your local sewage works, after treatment the “sludge” can be used to produce bio-methane as well as valuable fertilizers.
In time I believe all new builds and major renovation will have to incorporate solar panels both for heating water and using photovoltaic cell to produce electricity for localised use. The British government have recently put £60 million into setting up the basis for a series of new “eco towns”.
In coastal areas we will see the the building of wave powered generators to supplement electrical generators. These “Pelamis Wave Energy Converter “ are hinged floating snakes 180 metres long in 3 sections using hydraulic rams which produce 750kw and can power around 250 homes. Although a British invention the first installation was in N, Portugal , a new installation in the Orkney's will 3mw.
In tidal areas the sea every 6 hours ebbs and flows. "Tidal stream generators" will extract energy from moving water like under water windmills. It's estimated that in the UK these could produce up to 16% of the nation's power needs.
Of course living in France you can't have missed the arguments for and against éolienne or windmills, what isn't in debate (unlike where they are to be sited and who benefits from the power produced) is that they are one of the most mature of the alternative energy sources and will be with us for the foreseeable future. I would love to have a personal one on land but the initial cost is prohibitive, although I am investigating using the French Government interest free loan for green installations scheme.
In terms of transport the future is already with us, Poitiers and many other towns use LPG powered vehicles, La Rochelle (amongst others) provide free bicycles for visitors to tour the town and also electrically power cars for short local trips. With more people using hybrid cars and the evolution of hydrogen vehicles it won't be that long before our dependence on fossil fuels lessens considerably.
I have recently started to use a a free piece of software called “micromiser”, which when configured cuts your PC's use of electricity by up to 35% which according to the designers is around 30€ per year and around 330kw, just think if we all used it!
On show in San Francisco is the ultimate garment for those concerned about pollution – the EPA Dress – which wrinkles when it detects pollution giving it that just been pulled out of the laundry bin look – who said fashion is a crazy business?

Hot air
The only clear thing I could see was that no one was in agreement with anyone else. The South and Latin American countries would not sign (how much of that was to do with anti US sentiments rather than anything else is up for debate) Tuvalu condemned the final text, saying it would likely mean that their country would eventually be submerged if a higher drop in temperature was not adopted, while the Sudanese delegation said Africa would ‘incinerate’.
So what did we get in the end? An accord brokered by the US, China, India, Brazil and South Africa containing no reference to a legally binding deal, and no deadline for turning it into one. It was merely recognised by 193 countries not approved by them, which would have required unanimous support. This accord says that the world must limit temperature rises to 2 Celsius above pre-industrial levels. This is not a formal target, mind you, just a recognition that this should be a target! By the start of this month all countries were supposed to have spelt out how this was to be attained by curbing carbon emissions. But the deal doesn’t impose any penalties on those that fail to reach their targets.
It allowed for $30 billion over the next three years to help under developed countries combat the effects of global warming and $100 billion by 2020. But this financial help is coming from a mixture of sources not just ‘no strings’ aid, including a lot from the commercial sector who will have their own agendas. The developed world’s efforts will come under ‘rigorous, robust and transparent’ scrutiny and then what? A registry will be kept on pledges on climate mitigation measures seeking international support, whoopee. Finally, a review of the accord’s implementation will be held in 2015.
So in answer to the question…what did we get? A huge and expensive meeting which only showed where the world is divided, an ‘accord’ which does too little and isn’t legally binding, and proof that politicians should never be allowed to make decisions which affect us all; they should be made to consult us beforehand. The only good thing I can see that has come out of the Copenhagen summit is that it is so vague that it can only be improved upon in the coming months and years.
A recent find on the internet recent had me wondering what other ingredients the following product had in it for someone to have thought of it: Soil Association-certified edible shoe cream made from pure coconut oil. It can also be used in skin care, as lip balm, in drinks and on toast!

My top 10 New Year Resolution for a more environmental 2010
These are things that can be easily done and can save energy and CO2 production as well as saving you money.
1) If you have a central heating system installing a thermostat can help you save energy and money, on average around 15%. Reducing the temperature of your house by 1 degree Celsius can save 2%. Don’t over heat the rooms you don’t, use your radiator thermostat to run at minimum. At night run your heating at minimum - after all duvets are warm. Don’t have the heating on when you not at home, programme it to come on just before you arrive back.
2) Avenge your phantom load, a peculiar saying but all it means is – if you aren’t using an electrical item unplug it! Phone chargers, dvds, videos, etc all use electricity just by being plugged in and take all your electrical items off standby when not in use.
3) Change all your light bulbs for new energy efficient ones, they have come right down in price, I recently saw them at a local supermarche for 1€. The arithmetic make huge sense, the new bulbs use around 25% of the electricity of old style bulbs and last longer. If you use halogen spotlights the savings can be even more dramatic, I recently changed the nine 50 watt halogen bulbs in the kitchen for 60 led equivalents and the consumption went from 450 watts to 27 and they will last around 10 times longer!!
4) Convert your electricity to a green tariff; France now has a large number of environmental tariffs to choose from. www.energies-renouvelable.com is a good place to start looking.
5) Don’t drive so much it’ll save you money and the environment, get a bike and get fitter in the process, the average bike goes about 20 kmph so the 2km journey to the boulangerie will take a 12 minutes round trip as opposed to 4 or 5 in the car, not a huge chunk out of your day and you’ll use up 120 calories or so more a day!
6) Try taking longer journeys by train or by using a full car, the difference in carbon emissions is startling, a journey from Bordeaux to London produces 0.24 tonnes per person, a car with 4 people onboard 0.09 tonnes per person and by train 0.08 tonnes per person.
7) Remember your reusable shopping bags and not just for supermarche shopping, if you shop twice a week and use 2 bags that’s over 200 plastic bags saved a year.
8) Buy a water filter and fit it to your mains supply, they can be as little as 40€ to buy and the cartridges are about 30€ per year, but if you use bottled water at 1 bottle per person per day that’s 365 bottles saved and around 70€ not spent!
9) Reuse stuff, yoghurt pots and cans make great containers for seedling, nails in the workshop and buttons in the sewing basket. I’m sure you can think of many more uses for stuff headed for the landfill or recycling.
10) Compost all your organic waste not only will you save filling up landfills you’ll have a great source of nutrients for your garden and you’ll know where it came from.

A greener Christmas
Christmas is the time of year when most peoples thoughts turn to family and friends, buying your loved ones presents to show your feelings for them, providing the most lavish meals you can provide and for many travelling long distances to visit friends and relatives. This makes Christmas an environmental nightmare so I thought this month I’d look at ways of reducing your Christmas’s environmental impact.
Make something to take when visiting friends and rellies? Homemade jams, pickles preserves, bake a cake, make something, paint a picture, copy treasured family pictures, these all say more than buying something made by another.
Why not give your time and expertise as a present to friends and relatives who need it most, gardening, cleaning, babysitting or teaching someone a new skill.
Buy good quality presents that can be used and enjoyed over and over again. For children try wooden toys that will stand the test of time, try not to buy plastic toys or those that need batteries (if you feel you have to, buy a battery charger and reusable batteries for that present)
Look at buying used goods as presents, look at the local papers or online petites annonces for little used or unwanted gifts, not only will it be cheaper but you save on another being manufactured - I never had a new bike as a kid!
Avoid presents with excess packaging and buy from companies that are doing their bit to help the environment, use and give paper products made from recycled materials.
Don’t send a Christmas card to everyone you know, most people you know have an email address – send them an email card, there are some excellent ones out there and they won’t sit on the mantelpiece for a month and then get sent to recycling or landfill, and the message and sentiment will be the same.
If you must have a Christmas tree get a live one and replant it afterwards or buy the best artificial one you can get and use it year after year, use reusable decorations and lights, or make them, my mum used to make figures of shortbread and hang them on the tree.
For your Christmas dinner don’t go and get beans from
If you are going to a party or Christmas dinner why not offer to give others a lift it’ll cut down the number of car journeys made over the holidays.
Think before you agree to travel long distance to see friends and family, I know the emotional pull is great but are you going to see them soon afterwards? Why not see them then and have a get together with your own theme without the commercial pressures of Christmas. If you do travel why not use one of the many the online organisations which plant trees to offset your travel footprint.
Finally after the season clean up responsibly, recycle or reuse all you can,
A Merry Christmas and Happy New Year to All

A Snippet of Population Information
There is a promo on BBC TV at the moment that has Sir David Attenborough saying that in the 50 years that he has been reporting on the natural world the human population has increased threefold. Now I turned 50 in September and it horrified me, I am part of the increase – I blame my parents.
The estimated world population as of
The London School of Economics recently looked at the benefits of ensuring the world’s population has access to effective ways of contraception. It turns out that 40% of babies are unplanned so if you manage to stop them think of the consequences! It is also one of the cheapest ways of reducing CO2 emissions, through contraception it costs about 4.70€ per ton of CO2, cheaper than everything else analyzed except geothermal and sugar cane ethanol. By comparison wind power costs about 16.20€ per ton of CO2 saved.
I know many of us are passed the age where having children is an option but it might help if we take the message out to the younger members of the world.
With the colder weather around the corner I thought it might interesting to look at some more environmental ways of creating fabrics to keep you warmer this winter.
There are people who collect all their pets fur when grooming them and spin it into wool to make clothes! In fact there is more than one business who will do it for you, all you have to do is send it in the post and for a fee will spin it and make it into the garment of your choice. Weird but not so bad when you think where normal wool comes from, I’d do it but I know how bad my dogs smell when they get wet!!!
Chilean designer Alexandra Guerrero has figured out a way of spinning a yarn from of all things cigarette buts! Trillions of ciggie buts are thrown away every year and if properly cleaned can be recycled into a wool-like fabric and made into stylish, durable and eco-friendly clothing,
Following on from last month’s bamboo bicycle, bamboo clothing. Crushed it produces a fibre which can be spun and made into a luxurious fabric, benefits include, it’s very soft, warm in winter, cooler in summer, antifungal, antibacterial, UV protective and anti static, the yield from cultivated bamboo is also about 10 times that of cotton and uses much less water. Why isn’t it available more commercially?
You could probably team up your bamboo clothing on a bike ride with a new innovative and eco friendly bamboo cycle helmet called the Roof R06, fear not it has passed all the European safety tests, but is a tad pricey at 208€

The Greening of Cars
Today all car manufacturers are desperately (and expensively) trying to produce a so called green car. Most of this is driven by the
So today you can buy the first hydrogen fuel cell car the Honda FCX Clarity. This technology works something like this – the fuel cell converts hydrogen to electricity and water. The water goes out the tailpipe and the electricity powers a motor that drives the front wheels, to do this you go to the petrol station and fill up like a normal car, if you can find one that has a hydrogen pump. Easy but one of the most energy heavy things you can do ie produce hydrogen, hydrogen is always attached to some other element – e.g. H2O water – and takes a very complicated and expensive plant to do the separating and a huge amount of electricity power it. So until the technology becomes more advanced, the methods easier and electricity comes entirely from alternative generating methods it will take a lot of fossil fuels to produce hydrogen to produce a zero emissions car, so it’s a question of semantics really because somewhere down the line it’s polluting - a lot.
The same goes for all the battery powered cars like the G-Wiz, the up coming Chevrolet Volt and the lovely little Tesla, based on the Lotus Exige, until an awful lot of the electricity it takes to charge them comes from alternative generating methods they will still pollute.
The most mature of the technologies seems to be the hybrid vehicle seen in the likes of the Toyota Prius and the Lexus range. This is a system which the vehicle has both a petrol engine and an electric motor, the petrol and kinetic energy charging the electric motor batteries when running on longer drives and higher speeds and using the electric motor when being driven in towns. A great system that cuts the mile per gallon in fuel that car uses. But these also have their problems, if you live in the middle of the country, like I do, and most of your driving is at 90 kph you will just be using the petrol engine and you will not see any significant bettering in consumption, They work really well if you live in a town and do a little driving on the open roads. if not you’d be better off buying one of today’s highly efficient diesel cars which return over 70 mpg.
Recent legislation in France – indeed the whole EU – means that all petrol needs to have a percentage of bio fuels added to them. The new 95-E10 has 10% ethanol from the likes of maize added to it, which is fantastic, but please be aware that cars built pre 2000 may not be able to run on it, over a few tanks of this fuel it can create problems with the pipes and connectors in your engine. So if your car is pre 2000 be prepared to use 98 fuel, although that seems to be a rare beast these days.
It’s not the only problem that this fuel has, a friend recently was filling up in a petrol station in Angouleme when a beautiful new Lamborghini drove in and the driver noticed the new sign on the side of the pump “95-E10”, went to ask the attend and after some animated conversation strode back to his car and screamed off into the distance. It seems that supercars can’t run on it either

The Cost of Celebrity!!!
Many treehugging celebrities seen all over the media extolling the virtues of a green lifestyle own multiple homes, I know many people who read this have a second home but, Madonna has at least 6 London homes, and estate in Wiltshire, an apartment in New York and a Beverley Hills mansion. Nicolas Cage has a German medieval castle and a 40 acre private island. That apparently wasn't enough because in 2007 he bought a 12-bedroom home in Rhode Island, a castle in England and a $3.5 million home in New Orleans' French Quarter. There are many others and what's the problem? Each of these homes has a permanent staff using electricity, water, gas and pumping out CO2 just to keep them primed for the occasional visit of the owner. To get to these (im)modest piles many of these celebrities get in their private jet and burn much more fuel than they would do if their shared a plane with the rest of us, we who paid for their many homes in the first place by buying the album or watching the film.
I read a recent article about how, actress and celebrity wife and mother, Jennifer Garner always bought bio and fairtrade products and tried to use Farmers Markets as much as possible, laudable but then I saw a photo a few days later of one of her Farmers Markets trips using disposable plastic bags to stash her goodies in. Talking of shopping bags I'm sure you all have “bags for life” from SuperU or Intermarche at around 75 centimes each, but how about splashing out for something a little more stylish? 350€ for a Stella McCartney organic cotton shopper, around 700€ for a Hermès silk tote or 1,200€ for a Louis Vuitton canvas model? Veg shopping will never be the same again.
Some celebrities have branched out into other activities to, perhaps, supplement their incomes when their looks and popularity fade. Colin Firth has opened an “eco” store in Chiswick, SW London where he sells a variety of worthy goods which, if his bamboo, biodegradable, environmentally friendly bicycle which sells for over 3500€ is an example, will be monumentally expensive!
The recent death of Michael Jackson was a shock to many and a very sad event for all his fans. Michael, despite his foibles, was an advocate for all things environmental, listen to “Earth Song” , and a champion for racial equality which he is rightly applauded for – but did he really want to buried in a solid brass, gold-plated, 22000€ casket called the “Promethean “ which will never, ever degrade and will be a fixture in the California soil for all time! Personally when it's my time to shuffle off I will be burnt and scattered somewhere off the West coast of Scotland, but if I were to be buried I will be choosing the Hainsworth wool coffin, biodegradable and warm, not that it'll matter much.
