Biomasa
En general, existen dos enfoques principales para el uso deplantas para la producción de energía: el cultivo de plantas específicamente para el uso de energía (conocida como biomasa, primera y tercera generación), y el uso de los residuos (conocida como la segundageneración de la biomasa) de las plantas que se utilizan para otros las cosas. Vea la economía de base biológica. Los mejores enfoques varían de región a región, de acuerdo con el clima, los suelosy la geografía.
Biomass (plant material) is a renewable energy source because the energy it contains comes from the sun. Through the process of photosynthesis, plants capture the sun's energy.When the plants are burnt, they release the sun's energy they contain. In this way, biomass functions as a sort of natural battery for storing solar energy. As long as biomass is produced sustainably,with only as much used as is grown, the battery will last indefinitely.
In general there are two main approaches to using plants for energy production: growing plants specifically for energy use(known as first and third-generation biomass), and using the residues (known as second-generation biomass) from plants that are used for other things. See biobased economy. The best approaches vary fromregion to region according to climate, soils and geography.
During the five-years from the end of 2004 through 2009, worldwide renewable energy capacity grew at rates of 10–60% annually for many...
