Suppliers say parts of the National Grid failed causing disruption to transport, homes, and hospitals. At ten oclock, clive myrie will be here with a full round up of the days news. Now on bbc news in a series of documentaries we will explore how we can protect our precious planet, exploring Sustainable Solutions around the globe, and meeting the people at the forefront of driving change. How can we best protect our precious planet . Climate change and pollution are taking their toll, that much is not taking their toll, that much is now scientifically evident. But for all of the uncomfortable truth, we hold the future in our hands. In this film, we will be exploring Sustainable Solutions around the globe and meeting the individuals driving change in their communities. From housing, energy and fashion, these are some of the unique and surprising ways people from all walks of life are working to protect our planet. If youre in the winter, we can get waves up to 30 metres and that is a huge challenge. Surviving those extreme forces. Metres and that is a huge challenge surviving those extreme forces. The archipelago of orkney lies in the northern aisles of scotland, where the north sea and the Atlantic Ocean meet. It comprises of around 70 islands beset throughout the week by winds and gales. Only 20 of the islands are inhabited, but its very location is one of the remotest settlements in the uk means it is an ideal place to test new forms of energy. Such as wave, winds and tide. Wave energy is ultimately being driven by wind. In orkney, because weve got the full force of the Atlantic Ocean, it is very windy, so we have waves crashing against our shores. The energy is driven by a gravitational force, its where we get the biggest opportunies for tidal energy, tidal stream, that flows concentrated around the aisles of orkney and a few other places. Orkney was once dependent on the scottish mainland for power, but today, it fulfills its own engine needs. This tidal turbine powered by an orkney based marine firm is being tested by sea water moving its plates. The Technology Takes energy and converts it to electricity. The principle behind it is much like Wind Turbines on land. Wind turbines, the blades are being moved by the wind whereas in our tidal turbine the sea water moving blades and turning that into electricity through conventional generators. And how much energy does this generate . Right now, this turbine with the tidal speed that weve got at the moment which is just over six knots, we are producing 1. 8 megawatts of power to the grid. Locally, we are charged extra for the energy we use because of the old system of when youve taken energy from the mainland up to orkney. Its not just the technology that changes the marker, that causes real disruption here to allow these new technologies to really deliver what they can. Around the world, energy use remains a global challenge, which is why innovation in the Energy Sector is vital. We need to limit our energy use as we go forward. Particularly as the World Population continues to increase, the Worlds Energy needs are going to continue to rise. Orkney also has a rich archaeological heritage, so much that only a fraction has been excavated. For archaeologists like julie gibson, it is a race against time. The last 50 years, we about a third of our archaeological sites the last 50 years, we have about a third of our archaeological sites eroding, beautifully preserved and extraordinary as they are, on the one hand, they are eroding into the sea on the other. Part of the job is to try and keep an eye on these sites to see what kind of impact they have, what we are losing. Julie has beenjoined by doctor ingrid mainland, from the university of the highlands and islands archaeological institute. To explore the middens, which remains of ancient domestic waste that are being lost to coastal erosion. We are sitting on the beach which is near the part where they are interested in some of the archaeology thats coming out of the cliff section. There are the remnants of fish middens, that are being eroded away by the sea. It is very important because they tell us about humans activity in Human Behaviour in the past. From the size of the fish, we think that it is telling us that the site probably dates to the mediaeval period. This tiny place here up in the north of scotland was part of a vibrant trade in fish, it tells us about fishing stocks that were present in the medieval period. That information is relevant for understanding conservation practises today. This is a bit of cow skull that tells us with the people were eating themselves. So this is a viking norse cow from a thousand odd years ago. We are losing an awful lot of information about the past. I feel like there is some hope in having the interest of scientists like ingrid and these middens. The more information we can get, the more we can hang onto, you have to know about your ancestors. Approximately half of the worlds oxygen is produced by the ocean and it is the largest ecosystem on the planet. Over four and a half thousand miles from orkney, conservationists have come up with a unique idea to protect marine biodiversity, turning 2000 m2 of the caribbean into a living museum. With the exam we have created, about the global warming, it is a part of the ecosystem that makes humans be alive. I am roberto, i am the president of musa and also i am an artist in the museum. With more than 500 pieces of art, this museum in the sea is the largest underwater art installation in the world. It began with just three sculptures as attempt to attract tourists in order to relieve pressure on the natural reefs in the marine park. The story on how musa started is very peculiar, it consisted of Building Three poles made out of concrete and cover with some corals in order to have some distraction for tourists to visit and leave the natural corals alone. The most important part of musa is the purpose. The purpose is the art of conservation. It is all about placing beautiful contemporary sculptures under water in places where there is nothing but stone and sand and we place them there tourists will go to visit the museum instead of the natural reef. That is called discharging the reef. And that is what we were aiming at. To try, first of all, reduce the number of visitors to the natural reef. So today, 40 of the Million People that visit the musa bringing all these groups of people together and believing in this great idea of preserving our oceans it takes about 3000 l of water to produce one kilo of cotten textile, in fact, the clothing industry utilises more water than any other aside from agriculture. Fashion is a highly resource intensive industry. In the amount of clothing we consume is inevitably putting a strain on the planet. The pulse of Fashion Report published by Global Fashion agenda projects by 2030, global clothing consumption could rise by 63 , from 62 Million Tonnes today, 202 Million Tonnes. Today, to 102 Million Tonnes. One company in sweden created a revolutionary way of repurchasing a revolutionary way of repurposing old clothes into new materials for the fashion industry in order to better protect the planet. For me, it is been a big motivation to be able to go to work every day and feel a game contributing to making the world a more sustainable place. Recycled cotton close by transforming old clothes into Raw Materials for the fashion industry to use. If you look at average numbers to produce one cotton textile, takes about 3000 l of water, one kilo of chemicals, 16 kilos of Carbon Dioxide and then creates about half a kilo of waste. So it isa creates about half a kilo of waste. So it is a really resource intense industry. Really big footprints. The team created the first garment made from 100 chemically recycled cotton. Sword blue jeans became a new yellow dress and with this, this proof that the recycling process actually works, we were able to build the first industrially releva nt build the first industrially relevant chemical recycling plant which makes textile to textile recycling possible. Natural fibres and that way, we can avoid a lot of negative Environmental Impact associated with cotton or polyester, we are talking about reduced water use, reduced land use, reduced emissions, reduce chemical use and really make sure that we use the material that we have already once grown and taken out of the earth and put that back in to high value use so we can put that back in to high value use so we can take put that back in to high value use so we can take care put that back in to high value use so we can take care of the things that we already have. The used clothes come from this Storage Facility where they are shredded and not recyclable elements are removed before the clothes are broken down and turned into a fibre substance. We will develop technologies and promote new entrepreneurs and new usage to collect and sort textile materials. Other textiles are using technology to turn old clothes into new fibres and some firms now offer vouchers to shoppers bringing in used garments. It is everything from buying consciously, going for something that is long lasting and the fashion is produced today, asking a lot of questions in the store, where does it come from, its where you can actually really have an impact on the brands and then make sure you care for the clothes,. There is a need for people to express themselves, fashion is a good thing, we move around and would like to be unique and express ourselves and clothing is a very strong status marker. You cannot limit one group of people to express status. We can do good things about it. We can actually take back materials and give back which is a great thing. Not every solution to oui great thing. Not every solution to our environmental challenges is or try tech. Meet the millennial is fighting food waste by sharing food. I will see you next week. Visiting cafes in the northland neighbourhood once a week. Cedar bread and. It makes you feel connected to everyone, the community that i live in. It makes me feel like i am making a difference. 10 of it, one portion out which is why starting first place. Volunteers, food waste heroes, collect food that businesses wouldve otherwise thrown out. In the uk alone, 7 Million Tonnes of food and drink are thrown away each year. We have got right loves. She uploads pictures on the food sharing app, locals using the app then requested for free income collected. It attracts a wide variety of people. Just finish taking a finished school aged people, elderly persons. And fresh doughnuts or something, it is literally like a matter of minutes. If they like the food they see, the messenger and get the address. I am quite environmentally conscious and food wasting is a huge problem at a fee like this is a little bit i can do that makes a difference and also, it isa that makes a difference and also, it is a really nice way to meet people and feel like youre a part of the community. People are also sharing food they bought from themselves if they no longer needed, they uploaded. Polish student is collecting some unwanted ice cream. I think it is very crucial that we do this. This way, i get the food so ican spend do this. This way, i get the food so i can spend £5 a week for my groceries. Run from this lenten flat bya groceries. Run from this lenten flat by a small team. It has over a million users and 49 countries and 1. 7 portions of food have been shared on the app. But for the system to work, a basic human fear has to be overcome. Food is a really personal thing, we have built into the app, all the same checks and measures that you would expect from any other sharing economy, so uses of profiles, users have ratings and any listing can be reported to us, by the end of the day, you can choose to request a listing that you things look nice and you do not have to if you do not want to. People looking after the food also have to be happy letting strangers into their home. Unless they want to steal a lot of bagels, i am not really worried. I feel like, if anything, it means i get to know the people in my community into they feel more secure. On the other side of the atlantic, this community is also opening its doors to strangers. As it embraces a bold new way of tackling the housing shortage. According to the oregon centre for public policy, two thirds of the states low income renters spend more than 50 of their income on housing. There are more than, there are the sleeping outside in the Emergency Shelter or in transitional housing. There probably three times that may people an additional night for those living in basements and garages and trying to stay housed that way. When officials plan to build small Living Spaces and homeowners backyards, at no cost to the owner, more than 1000 people signed up to register. Four we re people signed up to register. Four were ultimately selected to be a pa rt were ultimately selected to be a part of the pilot project. The test is to work with four homeowners to build an accessory dwelling unit in the backyard where families who are homeless can live for up to five yea rs homeless can live for up to five years and at the end of that five year period of time, the homeowner gains ownership and access to that unit for whatever purposes they desire. Known as accessory dwelling units, roughly 200 square feet. Homelessness is a huge problem and also around the world and i would love to contribute, but how . I could not donate lots of money because i do not have lots of money, but when i heard about the programme, andl but when i heard about the programme, and i had a backyard that really isnt being used for anything totally productive, it was just a perfect fit. I saw an article and my good friend saw it online somewhere and she e mailed me and said, this is the perfect thing for you. This is the perfect thing for you. This isjust a you is the perfect thing for you. This is just a you have is the perfect thing for you. This isjust a you have been is the perfect thing for you. This is just a you have been looking for, youve got to apply. And so i did. They were homeless for eight months before moving into her garden, they lived in their vehicle and in shelters. It was scary at first because of the shelters and because we we re because of the shelters and because we were going from place to place. |j feel like i feel like a millionaire, and that everything is falling into place. Home, stability, that is what i needed. I have my own Little Library over there and no one else can get it. There is a laundromat within walking distance, great public transportation, daycare, schools and parks. It really is a nice neighbourhood. They are a perfect fit and they are going to work out fine. We really get along well. They took longer than expected, but if theyre deemed a success , expected, but if theyre deemed a success, there are for 300 more. Many times there is a narrative that homelessnessjust isnt, many times there is a narrative that homelessness just isnt, and many times there is a narrative that homelessnessjust isnt, and that it cannot be solved in our lifetime. But i disagree with that in the response in the Community Says there is still will, people just need to know how. Across the world, there are people striving to provide sustainable and Innovative Solutions to some of our biggest challenges. High and low tech, large and small scale, they are working towards preserving the Natural Resources and protecting our planet. Hello there. This is the time or we ta ke hello there. This is the time or we take a look at the weather for the next ten days. And in a word. It is u nsettled. Next ten days. And in a word. It is unsettled. But in the shorter term, things look very unsettled indeed, in fact quite turbulent through saturday and heavy downpours and very strong winds for some of us, which could well cause some travel problems, thejet which could well cause some travel problems, the jet stream and which could well cause some travel problems, thejet stream and high in the atmosphere digging a long way south of the moment, and that dip in the jet stream has spun up a deep area of low pressure which you can see on our earlier satellite picture, the swirl of cloud in the centre of this area of low pressure, we got some pretty brisk winds you can see all the white lines squashing together, particularly across the half of the uk and that means that the shy was the developer across the area should whiz through fairly quickly. As is further north across the far north of england Northern Ireland and scotland for the wind will be later, the thunderstorm should be slow so it should give some localised flooding. The strength of the wind could cause particularly across england and wales, 50 miles proper wind was 60 in some coastal spots and that could cause some issues for Outdoor Events and certainly some issues for travelling, temperatures between 15 and 20 degrees. Saturday and sunday, certainly for a time, across southern areas. They will slowly ease through the day on sunday and does when start coming in from the northwest and so you show start to bring down some cooler air and some really cool air for the time of year across the northern half of the uk and showers along the spells of rain pushing erratically eastwards but have a look at sunday afternoon, and aberdeen, edinburgh, 1a to 15 degrees still clinging on across southern england. Sunday into monday, low pressure still goes by but the bars really opening up in the winds will be much lighter and there will be some sunshine and shows as well and starting to develop across scotland and Northern Ireland, sinking slowly softly eastwards, barely getting up to 20 degrees as we go through monday, we moving to tuesday with a ridge of High Pressure trying to build its way in and so that promises a drier interlude and as you see behind me, the weather systems will be gathering once again we are likely to see some outbreaks of rain pushing and twist the southwest and temperatures again 16 to 20 degrees and a little bit below this time of year. Uncertainty for this time of year, but low pressure moving through, potentially some strong winds and will keep an eye on then theres uncertainty on how windy it will be in those temperatures struggling to recover very much 20 or 21 degrees at best. Through the second half of the next week, the jet stream continues to blow strongly across the atlantic and that will bring areas of unsettled weather and there is of low pressure in the direction and there always be some uncertainty as a style low and how wendy it will be, and there are some interludes of how warmer weather, we will tap into that cool airfrom the north. We can sum up like this to the end of next week to the next weekend, when breezy at times, some dry interludes and generally it will feel rather cool. That is all for me. Bye for now. Tonight at ten, a major power failure hits large parts of england and wales, affecting nearly a million homes, and leaving thousands of thousands travellers stranded. Many were left stuck on trains as the power failed, one airport lost all electricity, and some traffic lights in london were knocked out. It happened in the middle of friday rush hour, with some of the countrys busiest stations brought to a standstill. No one seems to know what is going on. If you go in and ask for help, no one really knows what is going on at all. I went into the Ticket Office earlier and spoke to them and the guy advised they wouldnt refund me for our hotel because it was an act of god some hospitals had to rely on emergency generators, ipswich hospitals back failed ipswich hospitals back up system failed when the power went off
