the amount of rain. itjust keeps coming through tonight and in this pa rt coming through tonight and in this part of the world. we could see 60-80 part of the world. we could see 60—80 millimetres of rain through today and tonight. and then tomorrow we have got even more starting to develop at least the winds will slowly a bate develop at least the winds will slowly abate through tonight and tomorrow and in the south. but that doesn't have a greater risk of heavy showers tomorrow. the heaviest rain except to develop in central and southern scotland, northern england through the day moving its way gradually southwards and again giving another inch or possibly more. further south, as i say, some slow—moving thundery showers but getting cooler for next week.

hello, this is bbc news. the headlines: national grid says it will learn lessons after nearlyi million people across england and wales lost power on friday. what we saw yesterday evening was an exceptionally rare event, one that we haven't seen since 2008, but we will of course be looking very hard at what happened to make sure we minimise

disruption in future. michael gove says there'll be a bailout fund for businesses hit by brexit. real pay for millions of lower and middle—income earners is lower than it was a decade ago, says the tuc. the mother of missing teenager nora quoirin thanks search teams scouring the malaysian jungle for her. more than a million people are evacuated from their homes as a powerful typhoon hits china. now on bbc news, in a series of documentaries, we will explore how best 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 now scientifically evident. but for all the uncomfortable truth, we hold the future in our hands. in this film, we'll be exploring sustainable solutions around the globe and meeting the individuals driving change in their communities. from housing to energy and fashion, these are some of the unique and surprising ways in which people from all walks of life are working to protect our planet. here in the winter, we can get waves up to 30 metres, and that is a huge challenge — it's a challenge to survive in those extreme forces. the archipelago of 0rkney lies in the northern isles of scotland, where the north sea

and the atlantic ocean meet. it comprises of around 70 islands, beset throughout the year by winds and gales. about 20 of the islands are inhabited but its very location as one of the remotest settlements in the uk means it's an ideal place to test new forms of energy such as wave, wind and tide. wave energy is literally the energy in the waves but ultimately that's been driven by the wind. in orkney, because we've got the full force of the atlantic ocean, which is very windy, so we get a lot of very big waves crashing against our shores. tidal energy is driven by gravitational forces. where we get the biggest opportunity for tidal energy is tidal streams where there's a flow and that flow is concentrated around the islands in 0rkney and a few other places around the world.

0rkney was once dependent on the scottish mainland for power but today, it fulfils its own energy needs. this tidal turbine pioneered by an orkney—based marine energy firm is being tested by seawater moving its blades. the technology takes energy from sea and converts it to electricity. the principle behind it is much like wind turbines on land. the wind turbine, the blades are being moved by the wind whereas in our tidal turbine, this seawater is moving blades and turning that into electricity through conventional generators. and how much energy does a device like this generate? right now, this turbine with the tidal speed that we've got at the moment, which isjust over 6 knots, we're producing 1.8 megawatts of power to the grid.

locally, we are charged extra for the energy we use because of the old system when we needed to take energy from the mainland up to orkney. it's not just the technology that needs to change, it's the market and we need some real disruption there to allow these new technologies really deliver what they can for local people. 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 world's energy needs are going to continue to rise. 0rkney 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. in the last 50 years, we have about third of our archaeological sites eroding. beautifully preserved

and extraordinary as they are, on the one hand, and eroding into the sea on the other. so part of myjob is to try and keep an eye on these sites to see what character they have, what we're losing. julie has beenjoined by dr ingrid mainland from the univeristy of the highlands and islands archaeological institute to explore the middens, which are remains of ancient domestic waste that are being lost coastal erosion. we are sitting on the beach of dingieshowe, which is near the part of deerness. we're interested in some archaeology that's coming out of the cliff section. there is the remains of middens, fish middens and shell middens that are being eroded away by the sea. they are very interesting and very important because they tell us about humans' activity and human behaviour in the past. from the size of the fish,

we think that it's 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 mediaeval period and that information is relevant for understanding conservation practice today. this little bit of cow skull probably tells us what the people were eating themselves. so this is a viking norse cow from a thousand—odd years ago. we're losing an awful lot of information about the past. i feel like that there is some hope of having the interest of scientists like ingrid in these middens. the more information we can get, the more we can hang onto. you can't hang onto your ancestors but you need to know about them.

approximately half of the world's oxygen is produced by the world's ocean and it's the largest ecosystem on the planet. over 4,500 miles from 0rkney, conservationists have come up with a unique idea to protect marine biodiversity, turning 2,000 square metres of the caribbean into a living museum. with more than 500 pieces of art, this museum in the sea is the largest underwater art installation in the world. it isa it is a part of the ecosystem that makes humans be alive. 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 an attempt to attract tourists in order to relieve pressure on the natural reefs in the nearby marine park.

it takes about 3000 litres of water to produce just one kilogram of cotton textile. in fact, the clothing industry uses more water than any other, aside from agriculture. fashion is a highly resource—intensive industry, and 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 that by 2030 global clothing consumption could rise

by 63%, from 62 million tonnes today to 102 million tonnes. 0ne company in sweden created a revolutionary way of repurposing old clothes into new materials for the fashion industry, in order to better protect the planet. for me, it has been a big motivation just to be able to go to work every day and feel that you contribute to making the world a more sustainable place. renewcell recycles cotton clothes sustainably by transforming old clothes into raw materials for the fashion industry to use. if you look at average numbers, to produce ikg of cotton textile, it takes about 3000 litres of water. ikg of chemicals. i6kg of carbon dioxide. and then it creates about half a kilo of waste. so it is a really resource—intense industry. so we leave big footprints. in 2014 the team created the world's

first garment made from 100% chemically recycled cotton. so old blue jeans became a new yellow dress. and with this proof of concept, this proof that the chemical recycling process of cotton actually works, we were able to build the first industry relevant chemical recycling plant in kristinehamn, sweden. it makes textile to textile recycling possible, it closes the loop on fashion financial fibres. and in that way, we can avoid a lot of the negative environmental impact associated with cotton or polyester. we are talking about reduced water use, reduce land use, reduced emissions, and reduced chemical use. and really making sure that we use the material we have already once grown and taken out of the earth, and put that back into high—value use, so that we take care of the things that we already have. the used clothes come from the storage facility. they are then shredded,

and non—recyclable elements like buttons and zips are removed, before the clothes are broken down and turned into a fibre substance. we develop sorting technologies, promote new entrepreneurs and new usage of collected and sorted textile materials. other companies across the world are also working on technology to turn old clothes into new fibres, and some firms now offer vouchers to shoppers taking back used garments. there are several actions a consumer can make. everything from buying consciously, so when you buy, go for something that is long lasting. fashion that is produced today, ask a lot of questions in the store, where does it come from, how is it produced? that is where you can actually really have an impact on the brands. and then make sure you care for the clothes in the right way. so, whatever you do, there is an imminent need for people to express themselves. fast fashion is a good thing. we move around and we like to be unique and express ourselves.

clothing is a very strong status marker. we cannot sort of limiti million people to express status. if we can do good things about it, it has its virtues. you can actually take back materials and give back, which is a great thing. not every solution to our environmental challenges is ultra high—tech. meet the millennials fighting food waste by sharing food. see you next week! poppy visits cafes in her north london neighbourhood once a week. three large loads of seeded bread, and a focaccia. brilliant. it's something to do which makes me feel connected

with everyone around me, like the community that i live in. it makes me feel like i'm making a difference. i also get 10% of it, or one portion out, which is why i started using it in the first place. volunteers like poppy, so—called food waste heroes, collect foods that businesses would otherwise have thrown out. in the uk alone, 7 million tons of food and drink are thrown away each year. so, we have got white loaves. poppy uploads pictures of each item onto the 0lio food sharing app. locals using the app can request it for free and come and collect it. it attracts a wide variety of people. just finished school age people, through to, like, really old people. elderly persons. if i wrote something really good,

like fresh doughnuts or something, it's literally a matter of minutes. if people like the food they see, they message poppy and get her address. hello. are you poppy? yes. here you go. i am quite environmentally conscious. obviously food waste is a huge environmental problem. this is, like, the little bits that you can do that makes a difference. also it is a really nice way to meet people and feel like you're part of your local community. people are also sharing food they bought for themselves. if they no longer need it, they upload it. polish student kasha is collecting some unwanted ice cream. i think it's really crucial to fight against the food waste. also, i am a student, so this way i get free food. so i can spend £5 a week for my groceries.

0lio is run from this london flat by a small team. it has over a million users in 49 countries, and more than 1.7 million portions of food have been shared on the app. but for the system to work, a basic human fear has to be overcome. food's a really personal thing. we have built into the 0lio app all the same checks and measures you would expect from any other sharing economy. users have profiles, they have user ratings, any listing can be reported to us. but at the end of the day it's up to you. you can choose to request the listings that you think look nice, and from the people you want to share with, and you don't have to if you don't want to. people looking after the food also have to be happy letting strangers into their home. unless they want to come and steal a lot of bagels, i'm not really worried, to be honest. i feel like, if anything, it means that i get to know the people in my community

and i feel more secure. 0n 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 city's housing shortage. according to the oregon centre for public policy, two—thirds of the state's low income renters spend more than 50% of their income on housing. there were over 11,100 people on a given night who were either sleeping outside in an emergency shelter or in transitional housing. there are probably three times that many people on any given night who're couchsurfing, living in basements and garages and trying to stay housed that way. when officials here announced plans to build small living spaces in homeowners' backyards, at no cost to the owner, more than 1,000 people signed up to register. four were ultimately selected to be part of the pilot project.

the test is to work with four homeowners to build an accessory dwelling unit in their backyard, where families who are 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, the homes are roughly 200 square feet. homelessness is a real problem in portland. and obviously in other parts of the world, too. and i would of course love to contribute. but how? i couldn't donate lots of money, because i don't have lots of money. but when i heard about the programme, and i realised that i have a backyard that really isn't being used for anything, totally unproductive, it was just a perfect fit. i saw an article in the oregonian, and then my good friend saw it online somewhere,

and she emailed me and called me and said, "martha, this is the perfect thing for you, this is just what you've been looking for, you've got to apply." so i did. sherry and sobeyda were homeless for eight months before moving into martha's garden. they lived in their vehicle and in shelters. it was scary at first because of the shelters, and because we were going from place to place. i feel like a millionaire. i feel like i won $1 million and everything is falling into place. a home, the stability, that's what i needed for her. i like books, a lot. i have my little library of them. i can finally put that somewhere where i can get it and nobody else can. there's a laundromat within walking distance, great public transportation, several grocery stores, daycare, schools, and parks. it's a really nice neighbourhood for sherry and her daughter, they're a perfect fit, i think.

they're going to work out fine. we really get along well. the pilot project took longer than expected, but if the houses are deemed a success, there are plans for 300 more. many times i think there is this narrative that homelessness is just an intractable problem and it cannot be solved in our lifetimes. i actually disagree with this. i think the response from the community says there's still stomach, there's 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 earth's natural resources and protecting our planet.

hello. whilst there will be some sunshine around this weekend, it's not the ideal weekend if you've got travel plans or plans for the outdoors. some heavy downpours still to come today and through the weekend. today, the focus really is on the strength of the winds, particularly for england and wales. an area of low pressure has been with us since yesterday, slowly moving its way eastwards. strongest winds on the southern edge of it and, as that pushes its way east, we continue to see those strongest winds feed in across england and wales especially. winds over 40, 50 mph. nothing untoward for winter or autumn, but we are in mid—august.

that will cause a few trees to come down, no doubt, given that they are in full leaf, and some disruption to travel plans. the strongest winds in the south. we will continue to see some showers and more persistent rain in central areas. further north, the winds will pick up later across the hebrides, touching gale force, but for much of scotland, northern ireland, lighter winds today. whilst we will lose the persistent rain across the far south of scotland, we will start to see some intense thunderstorms develop elsewhere. if you get caught underneath those, there is a risk of some flash flooding, but with them being slow—moving, some of you will sit under sunny spells for the rest of the day. outbreaks of heavy rain across northern england, with the wind picking up through the afternoon. the winds remain strong across the midlands, wales and southern england throughout. the showers perhaps becoming fewer in number with a bit more sunshine around. temperatures this afternoon, down on recent days — 22, 23 in the south and east, mid—teens across parts of scotland. into tonight, we continue with some dry weather across the far south, but more in the way of rain for the north of england, into parts of north wales, and rain comes and goes across scotland and northern ireland. a strengthening breeze in the north of scotland. temperatures here around 9 or 10 degrees, but most in the low to mid—teens as we start sunday.

it will be not quite as windy across southern areas compared with today, but northern areas feeling a bit breezy. clearing away some of the early rain in northern scotland, and brightening up as well in northern ireland, but for central and southern scotland, the far north of england, there is potentially heavy and persistent rain, which could cause further issues. some thunderstorms brewing across central and western parts of england and wales, but the brightest conditions in the south—east corner — 22, 23, compared to up to 12 or 13 in the north of scotland. that cooler air pushes for all of us this week. it's going to be a week when temperatures are below average for the time of year and we'll see some further rain at times, but also still some sunshine.

this is bbc news, i'm lukwesa burak, the headlines at two. the energy watchdog demands an explanation from national grid after nearly one million people across england and wales lost power on friday. the electricity provider says it will learn lessons from the incident. an incredibly rare event, the simultaneous loss of two large power stations. the normal protection systems we have responded normally, but the loss was so large that we went into our secondary systems. that we went into our iam greg i am greg mckenzie at king's cross station, where services have now resumed to a normal saturday afternoon service, but much of the lines were affected across england and wales yesterday following that power outage. michael gove says there'll be a bail—out fund for
