Photovoltaic Costs are still high Opportunity for stand-alone systems for isolated areas Governmental working group is currently conceiving a solar photovoltaic program Brazil is the greatest world silicon exporter, but has no photovoltaic components manufacturer Solar thermal– low temperature (water heating) Consolidated industry (more than 15 manufactures) Significant market share (replaces electric showers) Solar thermal – high temperature (CSP) Costs are still high There is room for applications at specific regions, such as the Northeast Region Studies are under way to support the development of the basic project of a solar thermal power plant in the Northeast Region Solar Energy in Brazil
Final Remarks • The Brazilian energy policy aims at to assure at least the current level of participation of renewable energy in our Energy and Electricity Matrices, while considering its sustainable development, reasonable prices, energy efficiency and security as well as access to all population • Diversification of our electricity matrix is desirable. However we have to consider (and foster) the stage of development of new renewables and associated costs • Hydropower will still have a major role in our system over the next decades • Brazil intends to develop its supply resources, including those in the Amazonian Region, but in a very strict sustainable way, i.e., taking into account the social, environmental and economic dimensions
