Environmental Background:

  Many of South Africa's environmental conditions make South Africa a good candidate for the use of medical vehicles powered by photovoltaic cells.

Geographic Considerations:

Climactic and Health Considerations:

Energy Resources:

  Much of South Africa's electricity comes from coal. Though coal can be found quite easily in South Africa, it is difficult to extend power lines to rural inhabitants in South Africa in order to provide them with electricity. Approximately 20% of South Africa's rural population are not expected to get utility grid electricity for quite some time. Therefore, renewable energy are an excellent prospect for the future.

  Renewable energy technologies make use of resources that are bountiful, inexhaustible, and affordable for poor households. South Africa already uses water and wind to create power. A steady wind along its coast is strong enough to produce 1.9 gigawatts of power. There are also some farms and towns that use small hydropower stations to produce energy.

  On the other hand, South Africa and its neighboring countries are believed to have the greatest potential for harnessing solar energy the world. South Africa already averages over 4.5 kWh/m2 of solar energy output per day. Therefore, South Africa is the perfect place to utilize photovoltaic power. In addition, renewable energy technologies avoid the harmful environmental effects of burning coal or oil to produce power. To this day, over 2,000 stationary clinics in South Africa use photovoltaics for electrification. In addition, remote hospitals in South Africa use photovoltaics to provide electricity for lighting, refrigeration of medicines, computer systems and x-ray machines.

  Many businesses providing photovoltaic equipment are already located in South Africa. There are photovoltaic manufacturers, wholesale suppliers, retail sale businesses and service businesses already established throughout parts of South Africa. These companies can provide a variety of products ranging from photovoltaic modules to photovoltaic module mounting systems. For this Joint Venture, we would like to purchase most of the required materials and subassemblies from firms already existing in South Africa.

  Much can be gained by using this type of renewable energy to power our medical vehicles.
