>> hello and welcome to "global 3000." the number of older people is growing faster than any other age group worldwide. in europe, this has already led to a shortage of nurses and care givers. time to think of new recruitment strategies. here is what we have coming up. new frontiers for global care. chinese nurses prepared to work in german retirement homes. child laborers denied. we need children in bolivia who have started their own trade union. and net metering.

we explain what's behind this concept for renewable energy. rich industrialized nations like germany are rapidly running out of qualified care givers. there are several reasons for this. firstly, the population is aging. and secondly there are simply too few people interested in training to become qualified nurses or care workers. of course, the promise of a relatively low wage for such a demanding job certainly does not help. in germany, there are currently an estimated 18,000 to 30,000 unfilled positions in hospitals and nursing homes. things could not mean more different in -- things could not be more different in china. there, " the elderly are still mainly looked after by families, thousands of newly-trained nurses cannot find jobs. in the hope of creating a win-

win situation, germany has launched an initiative to entice chinese care givers to work in hospitals over here. the first group of some 150 nurses is currently busy polishing their language and cultural skills as they prepare for a new start in europe. >> these two women are practicing conversation in germany. "hello, what is your name? i am honors." every day useful sentences. they have been studying language for six months. their teacher gave them new german games. their language skills are pretty good now. teacher plays them pop songs from germany. they have learned that germans are punctual, bavaria's like sauerkraut, and sausages are popular across the country.

>> when i think of aachen, i think of their special cookies called printen. >> when i fly to berlin, i will try all the local delicacies. >> it is not yet clear if or when they will actually fly to germany. this is a pilot project, and it is only just getting under way. education in china is strict. the day begins with the assembly and some exercise routines. petra is 23. her real namexu yoyu. she became her nurse -- she became a nurse because our parents wanted her to. but going to germany is her own idea.

gisela is 24. her real name is shen xiaoxi. she chose to take the course because she likes languages and wants to see the world. everybody on the course is a " -- fully qualified nurse. the training in china is considered to be very good. in chinese culture, the elderly are shown great respect. but is that the case in germany? the students on this course of been reading up on cultural differences. but what might they mean for daily life and work once they get there? >> in china, the young at help the old and the old accept their help. perhaps the elderly in germany tend to be more independent and not want people helping them. we will have to wait and see. >> in terms of qualifications, they are confident they are up to the task. in china, nursing care is done

by aids -- aides. as medical nurses, they are probably over qualified when it comes to routine care of the infirm. >> i dream of seeing the world and learn new languages. i like nursing, and now i have the opportunity of combining the two, working in my profession and growing abroad -- and going abroad. >> china and forces a strict one child per family policy. as a consequence, many children are rather spoiled and may not learn at home such skills as cocaine. the students have been warned that food in germany is expensive and very different. so the school gives them a crash course in cooking. >> we like porridge for breakfast, but germans prefer bread and milk. that will take some getting used to.

>> chinese people are often rather loud when we get together. germans might be quieter and not like so much chatter. for example, on the bus, and a little worried i might disturb people because i do not yet know all the rules and customs. >> these suitcases belong to another group of nurses, who are about to head off to japan. the school was already placed more than 1100 years as in japan, singapore, and the middle east. now its aims to conquer the european market, even though the need for nurses within china is growing because its society is aging fast. >> the world health organization says china does not yet have an up hospitals or nurses to look after its people -- enough hospitals and nurses to look after its people. the demand should be there, but in fact hospitals avoid hiring more staff, because it would be

expensive. so, many nurses are very overworked. >> the course at this for-profit school costs more than 1000 euros. the students live eight to our room during the program, but they do not seem to mind. the hope of better pay and better conditions in germany disperse them on. -- spurs them on. >> i heard that working hours are flexible. that you can choose to do early or late ships. it is not like that in china. >> i am looking forward to germany. i have have little opportunity to shape my love -- my life the way i want to. friends and family are always giving me advice. i shall decide how i want to live. >> the students do not have work

contracts yet or know how long the contracts might run. but they do say they hope to stay in germany for a long time. >> and these nurses are due to arrive over the coming months for an initial stake of three years to five years. then both sides will assess where the scheme should become a model for the future. there are few things that most nations in the world can agree on, but one for sure is that children should be scared many of the terrible on goings would otherwise like to simply sum up as reality. and yet some 200 million children around the world are forced to work, often under slave-like conditions. in response many adults lead child labor should simply be banned -- believe child labor should simply be banned. many say that's unrealistic and what better working conditions instead. to that end, they've been

organizing trade unions which cannot be found around the world. for instance in montpelier, india, and pakistan. on the african continent, there are 21 youth organizations which act at the local and regional level. in latin america, groups of organized and a number of countries including peru, ecuador, and bolivia. the children say that a complete ban on child labor is counterproductive. with no one else providing for them, what they need is a fair chance to provide for themselves. >> henry is 15 years old. his workday starts at 10:00 in the evening. he buys a box of cigarettes and then resells the individual cigarettes. >> i have to work so i can make money for my family. i tried to sell as many as i can. >> henry lives in el alto, a sprawling city right next to the bolivian tola paz.

-- capital la paz. five days a week he works the night light district. in the seedy bars and clouds he sells cigarettes for 25 cents apiece. sales picked up as the night advances. henry has to know where and where not to go. >> there are lots of criminals. organized gangs. and for me, they are the biggest danger. >> henry has been doing this since he was 8, so he knows the territory. and he knows about the police. if they catch him, they will take his money away and his cigarettes. working children do not count

for much in bolivia, and what he does is illegal. henry bring some the equivalent of about four euros and night. this is where he and his family lived. lunch is rice, onions, and japan. -- and chicken. nine square meters for four people. henry, his two sisters, and their mother teodora. there is room for two mattresses and a stove, and not much else. his mother gets just 75 euros a year in support from the state. it is not enough. >> so that we have something to eat every day, all the children have to work. they do not have a father anymore. he left us. >> that was seven years ago. henley has tried to take over his role.

the apazas live in juntuma, the poorest neighborhood of el alto. every day after school, henry and his sisters that the bus into town to go to work. it is cold and windy here, 4,000 meters above sea level. the population has soared to more than 1 million over the past two decades as people live -- leave rural areas. henry's younger sister cielo is 8. she still sticks of chewing gum in the restaurants downtown. cielo and 14-year-old joselina or four hours every afternoon. >> some people get angry and tell us to go away.

they say we have been brought up badly. they do not buy anything, and they do not understand why we have to work. >> the two girls have made six euros, a good day. they buy new stock, always at victor's kiosk. >> i have known the two since they were babies. some working children do well. others get into trouble and become addicted to alcohol or glue. " libya is the poorest country in south america. about 1 million children work here. they earn much less than adults and have virtually no rights. so, child workers have got together to form their own labor unions. 10-year-old carlo collapse paper and cardboard -- carla collects paper and cardboard.

wearing the unions blue vest and a protector from attacks at night. she earns one euro purse back. she has to look after her mother. question is also in the union, and he has big plans. -- christian is also in the union and he has big plans. >> i want to buy new shoes and i want to go to college. >> henry is a union delegate. he and his colleagues are working on a letter to the government, asking it to enforce their wages and provide free medical insurance. the union wants to see child labor fully legalized. >> we got the government to change the constitution. it no longer bans trout labor out right, only the exploitation of children -- it's no wonder bans child labor out right, only the exploitation of children. >> being a union activist has

changed henry. he used to live on the streets like many job workers, and he had a bad habit of sniffing glue, which is addictive. dependency is a major problem along bolivia's child workers. >> when you are high on blue, you do not feel the cold. you feel light. but when it wears off, you feel the hunger and the cold again. sniffing glue did me a lot of damage. >> now he's sober, and he has set himself some ambitious goals. >> i want to run my own company, have a house and the car. i would like to become an important person. >> henry points out that the socialist president evo morales was also once a child worker.

>> in fact, bolivia's presidents was born into a family of subsistence farmers. to see her son achieve great things is also what drives jana stroe. she is a new york cabby. she meets scores of people on the job. here is her take on globalization. >> my name is jana stroe. i am 57 years old. i lived here and queens, new york -- i live here in queens, new york. i'm a taxi driver. i drive cabs for a very long time. almost 26 years. and how much am i making? new yorkers never say, right?

[laughter] >> globalization for me as everything that is around us. globalization means we have to stand up for our -- everything that we do. the environments, living, and health. first of all, i work, and it makes me happy when i'm driving and when i meet people all over the world. we call us at the ambassadors of new york. my favorite is my country's

food, which is romania. being a new yorker, we eat all kinds of food, international food, because here, we can taste any kind of food. it would be nice to visit anywhere. when you have money, you visit any country in the world. [laughter] my son is in first-year law school, so it would be the biggest accomplish in my life for him to finish law school. and me to be free from not driving any more cab. [laughter] >> creating consensus on pretty much anything can prove tricky in the middle east. the sun and the wind don't care about political boundaries, and

that's why many hopes rest on them to tackle 11 non-'s chronic power outages -- lebanon's chronic power outages. a new scheme allows those producing electricity from wind or solar technology to use the power grid as kind of an energy deposit. if it works, this could not switch off thousands of diesel generators. >> the plastic bags produced in the factory are sold across lebanon and several other middle eastern countries. he has a workforce of 50, and the factory runs a day and night. but its electricity from the grid only a few hours a day. generators at the factory provide the rest. >> we need lots of diesel.

the big 650-kilowatt generator uses 80 leaders an hour, or more than 1,500 liters a day -- 80 liters an hour, or more than 1500liters a day. that much costs between $12,000 and $13,000. every day. >> burning just one leader of diesel fuel results in emissions of about 3 kilograms of carbon dioxide. plus, there is it in noise. he would like not to run his generators 24 hours a day and instead switch to clean energy. >> we're looking for alternative sources of energy. when would be great. the cost of running a generator is just too high. >> he contacted ralph steffen,, a clean energy consultant in

beirut and often an interesting project. it involves setting up green energy generation systems, linking them to the grid, and installing a net metering system to track the close of electricity. if you feed grain energy into the grid, you get credit so you can later take the same amount of energy from the grid. it promises to be a good deal, especially for companies. >> they have sundaes or they do not work. the net meeting could be used to supply the grid, where they are producing electricity from either the wind or the sun. and this sunday's where they are not working. this is a good incentive, i think. >> energy from renewable sources button to the grid is available to everyone. it also helps make the system more reliable, reducing the frequency of power outages. united nations development agencies set up the project called cedro.

its engineers have drawn up an interactive wind map of lebanon, to identify the best locations for new wind turbines. more and more individuals and companies are calling up to ask all they can generate clean energy. >> it's a very good solution. first it gives you electricity. then it reduces co2 emissions and to save the environment. and at the same time and a few years it will be just as cost- effective, just the same price as conventional electricity. >> a number of schools are involved in the project. the lights and now stay on even when there is an outage. at least on sunny days. thanks to the solar panels on the roof. excess energy goes into the grid, earning the schools credits porta-potty days. then they can draw power from the grid. as long as there is no outage.

overall, energy costs for these schools are trending lower. cracks before we had this system, be used to have our own generator, which costs a lot. and most of the neighbors here, they asked me, what's this and what do we use it for? and they are very eager to do such a project. i don't know if the cost would make a difference. so, it it it's cheaper, they will all do it. i'm sure of that. >> a few weeks earlier, engineers involved in the project in lebanon attended a seminar here in berlin. it was about the integration of wind and solar energy into the grid, how it can make the grade more stable, the latest technology, and the problems that tend to rise in such ventures. >> it makes us see what is

possible. and it helps us set as well steps into how to achieve the goals we have sets. so, we take the knowledge we have seen here, the way the germans -- the germans have done it. >> rima assaf is an electrical engineer. she works for the national electricity company and is in charge of linking up renewable energy sources to the grid. she says she found the seminar useful. and it fired her imagination. >> i will apply and design and construct a pv-system in my home, okay? because in my region where i live, the radiation is high. >> she is building a new house

in the town of baalbek, 90 kilometers east of beirut. there is plenty of sun and wind at their -- there. >> finally, i think we need about four or five months to build the system. >> for now, two car batteries help out at her home when there is an outage. this photovoltaic systems on the roof of a high-rise in beirut. rima install the net metering equipment here. every day the sun shines, electricity costs for the building declined. and now they rarely have to fire up the diesel generator. >> what do you think? could such a scheme also makes sense for you are? tell us your thoughts by visiting us on facebook or our website.

and that is a "global 300" for this week -- "global3000" for this week. this week. thanks for watching.
