Cleaning up Delhi's air 凈化新德里的空氣
Solving South Africa's power crisis 解決南非能源危機(jī)
文字稿
It's morning rush-hour in Delhi. Cars slowly inching. A city that's slowly choking. Delhi's air is the worst in the world. It's 25 times more toxic than the safe levels set by the World Health Organisation and cars are responsible for nearly half of the most dangerous pollutants. Every week more than 3,000 new cars are added to the roads of this city. The government's been trying to restrict their use and has banned cars that are more than 15 years old.
新德里清晨的高峰期，車流緩慢地向前挪動(dòng)。這是一個(gè)逐漸被嗆得透不過氣來的城市。新德里的空氣質(zhì)量目前是世界上最差的，其空氣有毒性指數(shù)已高出世界衛(wèi)生組織設(shè)定的安全指數(shù)25倍，而其中近一半的最危險(xiǎn)的污染物來自于汽車。每周仍有超過3000輛的新車加入到這座城市的道路中，盡管政府一直試圖限制車輛的使用，并已禁止車齡超過15年的汽車上路。
Power from the sun. In South Africa's Northern Cape, sunshine is in abundance. Harnessing that power would seem to be a logical step towards solving part of the country's energy crisis. It's a crisis which is well documented – a strained grid, blackouts and now a price increase. As South Africa's predominantly coal-powered power plants strain to meet the demand, renewable energy is becoming more attractive.
來自太陽的能量！南非北開普省日照充足，而利用這些來自太陽的能量解決國家部分能源危機(jī)的問題看上去是一個(gè)合乎邏輯的步驟。一個(gè)超負(fù)荷的電網(wǎng)、經(jīng)常性的斷電和日益上漲的能源價(jià)格都充分的證明著能源危機(jī)的存在。目前，作為南非主要依靠的煤炭動(dòng)力發(fā)電站已很難滿足需求，可再生能源正變得越來越具有吸引力。
