Cleaning up Delhi's air 净化新德里的空气
Solving South Africa's power crisis 解决南非能源危机
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.
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.
