Cleaning up Delhi’s air 凈化新德裡的空氣
Solving South Africa’s power crisis 解決南非能源危機
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.
新德裡清晨的高峰期，車流緩慢地向前挪動。這是一個逐漸被嗆得透不過氣來的城市。新德裡的空氣質量目前是世界上最差的，其空氣有毒性指數已高出世界衛生組織設定的安全指數25倍，而其中近一半的最危險的污染物來自於汽車。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，並已禁止車齡超過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傢部分能源危機的問題看上去是一個合乎邏輯的步驟。一個超負荷的電網、經常性的斷電和日益上漲的能源價格都充分的證明著能源危機的存在。目前，作為南非主要依靠的煤炭動力發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。
