Overview of biomass energy
Overview of biomass energy:
Energy can be classified according to their morphology: solid fuels, liquid fuels, gaseous fuels.
According to forms of energy can be divided into chemical energy, hydro, nuclear, power, solar, biomass, wind energy, ocean energy and geothermal energy. From the impact on the environment ,can be divided into clean energy and non-clean energy, the former may also be called green energy. According to the aspect of whether it renewable, can be divided into renewable and non-renewable energy.
According to the form of the development of energy use can be divided into primary and secondary energy. With the rapid growth of Chinese economy, fossil fuel-based energy consumption sharply increase, and the pressure on the environment is growing. In 2003, China reached 823 million tons of carbon dioxide emissions, ranking second in the world, sulfur dioxide emissions by more than 20 million tons, ranking first in the world, the acid rain area accounted for more than 30% of the land area.
After 2005, China's emissions of carbon dioxide over the United States ranked first in the world. 70% of China's carbon dioxide emissions, 90 percent of sulfur dioxide emissions, nitrogen oxide emissions from coal-fired two-thirds of all. With increasing pressure from environmental protection, the implementation of energy conservation, promote low carbon living is imperative.
Biomass energy
In the above context of the international energy situation, biomass energy is growing at rapid trend of rapid development.Biomass is fixed by the photosynthesis of plants to solar energy on Earth, most likely to become one of the major new energy in the 21st century.It is estimated that Plants store energy equivalent 10 times world's major fuel consumption for one year. And the amount of energy use is less than 1% of the total amount. It can efficiently utilize biomass energy through biomass conversion technology, to replace fossil fuels, thereby reducing dependence on fossil energy, reduce pollution to the environment caused by energy consumption.
Experts believe that biomass energy will become an important part of future sustainable energy, by 2015, 40% of the world's total energy consumption will be from biomass energy.
Biomass energy has the following characteristics: renewable, of high calorific value, low pollution, zero emissions, high density and so on.
