Zambezi River Basin electrical infrastructure
The estimated hydropower potential of the Zambezi River is in the order of 20 000 MW of which only 4 684 MW has been developed (Hirji et al. 2002). About 40 possible new hydropower plants with a total installation capacity of more than 13 000 MW have been identified in the basin. About 85 per cent of this capacity is on the Zambezi River itself while the remainder is on its tributaries. Close to half the mapped potential is in Mozambique, about 2...

Use of renewables and combustible waste for energy production in 2001; Latin America and the Caribbean
Approximately 12 % of the world’s energy supply comes from renewable energy sources (biomass, waste and other renewables, excluding hydropower).
The average renewable share in Latin America is higher than the world average,. But even if the energy supply from renewables will increase in Latin America, the percentage share of renewables of total energy supply is projected to decrease in the years to come. (World Energy Outlook 2004).

Total energy supply in 1995
Total primary energy supply per capita is a common, albeit an imperfect measure of energy efficiency in a country. For instance, neither the impact of climate on energy use (heating, cooling) nor the size of the country and the density of the population are properly taken into account when comparing countries. Energy analysts usually prefer to compare energy use per unit of output or per unit of GDP. However, the ratio has been presented here sin...

CO2 emissions from industrial processes and land use change
2 thematical maps:
(1) CO2 emissions from industrial processes (http://www.grida.no/climate/vital/09.htm): This map depicts the unequal distribution of industry in the world. The significant part of carbon dioxide emissions comes from energy production, industrial processes and transport. The industrialised countries consequently must bear the main responsibility of reducing emissions of carbon dioxide.
(2): CO2 emissions from land use change.(...

Trends in wind generating capacity
Global development of wind in the form of wind power plants between 1980-1995, in megawatts. Wind power represents one of the most attractive and clean alternative and renewable power sources, utilizing the inhert power in the atmosphere.

Annual flow of water to the Caspian Sea
Most of the water flowing into the sea comes from coastal rivers – currently supplying 300 to 310 cubic km a year. The Volga alone accounts for 80% of inflow. But it has dropped substantially during the 20th century, declining from about 400 cubic km in the 1920-30s to between 260 cubic km and 270 cubic km at present, due to various climatic factors and human activities such as dams built for hydroelectric energy production.
