Policies and market mechanisms for wind and other renewable energies in 15 developing countries in Asia, Africa and Latin America are just as varied as in industrialised countries, concludes a study by Germany's overseas development organisation Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ). Support mechanisms range from command and control subsidy programs through fiscal and customs duty stimuli to fixed feed-in tariffs for renewable energy. Electricity market liberalisation begun in many countries means that many companies can generate power for their own consumption or to supply third parties. This "could make a positive contribution to renewable energies," says the report. The study covers Argentina, Brazil, Chile, China, Colombia, Cuba, Dominican Republic, India, Jordan, Kazakhstan, Morocco, Mexico, South Africa, Tunisia and Turkey.
