Solar energy and sustainability Privileged by the high incidence of solar rays in its territory and the quartz reserves for the production of solar grade silicon, used in the manufacture of solar cells, Brazil is able to figure in a very comfortable situation for energy generation by half. of this century.
The sun provides heat and light and making the most of its energy contributes to sustainability. The sun is a source of renewable energy, natural, clean, available and infinite! It does not emit greenhouse gases, which contribute to the rise in the Earth 's temperature, generates no waste and generally replaces a costly and scarce fossil polluting fuel. In architecture, the Sun helps guide buildings, select materials that take advantage of light, help circulate warm air, and take advantage of external temperature fluctuations.
In addition, photovoltaic projects allow us to capture the sun's energy, either through photovoltaic cells (which turn light into electrical energy) or solar collectors (for water heating, for example).
