South Africa: Supermarkets, Naturally Cool | Global 3000

When used as refrigerants, flourocarbons can cause severe damage to the Earth's ozone layer. That's why a South African supermarket chain is changing direction to use natural and eco-friendly refrigerant technologies - and saving money and energy as a result.Electricity is especially costly in South Africa. In the last few years the price has been rising by nearly 30 percent annually. Meanwhile, power shortages have been reported. So a supermarket chain called Pick 'n Pay is investing in new equipment. Instead of using flourocarbon gases to cool its outlets, it's now using natural refrigerants.
