4. Read the article and answer the questions a to e.

Dubai´s Sustainable CityDiamond, the company behind Dubai’s Sustainable City, wants to build eco-friendly communities in the United Arab Emirates and export those projects to the rest of the world.

Navid Abdalah, the general manager, said that if the project is successfully implemented, it will play a key role in establishing Dubai as one of the most sustainable cities in the world by 2020. Speaking at the Canadian University of Dubai, he said: “If the Sustainable City project is successful, it will allow people to see an example of how sustainable living can benefit residents, communities and businesses, and that it can be repeated all over the region and all over the world”. If Abdalah’s predictions are right, the Government could get interested in building other sustainable cities in the country.

The community will include a school, a university, a planetarium, a country club and a community center with malls, and coffee shops. Also, the community will have a ‘green belt’ with 20,000 trees, a long water canal, a solar park, and water management system that will be recycled 100 per cent of waste water.

Thanks to this innovative project, the Dubai Municipality recently formed a special committee for sustainability to study other green initiatives.

“The biggest challenge here and in other countries is that the residents can benefit from living in a green community. Our target is to keep the

residents for a long time. Building green doesn’t need to be expensive as it is possible to find ways to reduce costs to around those of traditional construction”.

When people asked Navid Abdalah how this could be done, he said: “Investigate different elements in the design. Investigate everything: from energy-saving, air conditioning units, to the direction of the sun and the predominant wind direction.”

(Source: Taken from 2nd Graders Teacher’s Book)6. Read and analyze the information in the box. Then,

read each statement and decide whether it represents an advantage or a disadvantage of renewable energy.

Renewable energy: forms of energy that can be produced as quickly as they are used, such as wind and solar power. At present only a small proportion of the world’s energy needs come from alternative and renewable energy sources.

Non-renewable energy: form of energy which does not exist in unrestricted supply; such as fossil fuels like coal, oil and gas.

Answers:

a) _Advantage________ It is renewable and therefore sustainable, so it will never run out.

b) _Disadvantage______ It is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators.

c) _Disadvantage______ It is very expensive because it is a new technology and has an extremely large capital cost.

d) _Advantage________ Its facilities generally require less maintenance than traditional generators.

6

e) _Advantage________ It produces little or no waste products such as carbon dioxide or other chemical pollutants, so it has minimal impact on the environment.

f) _Disadvantage______ It often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors need clear skies and sunshine to collect heat and make electricity.

g) _Advantage________ Renewable energy projects can bring economic benefits to many regional areas.
