A major problem in Germany’s energy system is the role of coal in electricity generation. Unlike photovoltaics, where one single component, the solar cell, is replicated a 100 billion times and spread all around the world, bio-energy is something a lot more complex. The matter and energy created in this way end all up in thermal decomposition. The generation and use of bio-energy is the art to catch some of the energy before that happens. Biogas is another important sector of bio-energy. A major part of the energy distributed is derived from renewable sources. The main consumers of bio-energy in Europe are Germany, France, Sweden, Italy, Finland, Poland and Spain. The other newcomer in bio-energy since the turn of the century is biogas. Brazil is a model country for renewable energy implementation and use.
