The energy source used to make a product or which illuminated an office is hidden from our eyes. Just looking for a product or company´s name, how can you know whence comes the energy that brings light to their supermarket aisles or that feeds their factory machines?
The Solar Label was created to give visibility for something that is not seen – electricity.
In order to help them on its effort to spread this information to its consumers, the Institute for Development of Alternatives Energies in Latin America (Ideal Institute) and the Electric Energy Commercialization Chamber (CCEE) had launched the Solar Label, with the support of the German Cooperation for Sustainable Development, through Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and Germany Development Bank (KfW).
With this, we aim to encourage new projects on solar photovoltaic in Brazil.
Why should I know the origin of the energy used by enterprises?
If you are concerned about the environmental impact of enterprises activities from which you buy products or services, you must be aware of the origin of the energy they use.
Electricity can be obtained from different energy sources, some with greater environmental impact than others. Coal-fired power plants, for example, are highly pollutants and emit high levels of greenhouse gases, which cause global warming. The construction of hydroelectric has a direct impact on the local flora and fauna.
But the use of the so-called alternative energy represents a lower environmental impact, which is the case of wind farms, biogas systems and solar plants.
With most of its territory located in the tropical zone, Brazil is a country with a high incidence of solar radiation. According to the Atlas of Solar Radiation in Brazil, the country receive between 4.5 to 6.3 kWh/m2 kWh/m2 each day of the year. This means that the sunniest place in Germany, a leading global photovoltaic market, receives 40% less solar radiation than the least sunny place in Brazil.
Despite these favorable conditions, this potential is still untapped. The use of solar energy was not considered, for example, on the 2030 National Energy Plan and only in 2011 the first majors projects began to be installed in the country.
Using solar energy to produce electricity is a way to reduce greenhouse gases emissions and, in many cases, other environmental impacts associated with construction of energy projects. Moreover, the installation flexibility in several locations, mainly integrated to buildings in mini and micro plants, makes it a source with a high potential for expansion in the country so as to bring benefits to the national grid.
