Benefits of biomass energy
« on: September 25, 2014, 02:22:33 PM »
Biomass in the form of fuelwood was perhaps the first energy source used by human beings and was the main fuel till the industrial revolution, after which fossil fuels like coal and oil replaced biomass as the main fuels. Biomass is still an important fuel in developing countries. As per International Energy Agency, biomass energy accounted for 11% of the world’s final energy consumption in the year 2001 (Karekezi, Lata and Coelho 2004). This percentage was 18% for Latin America, 25% for Asia and 49% for Africa.

Biomass energy offers several advantages in the form of energy security, socio-economic development and environment.
Energy security

Decentralized biomass energy could help nation to substantially reduce dependence on fossil fuels.
Rural economic growth

Biomass energy could stimulate growth in farming, forestry and rural industry leading to overall rural development. Biomass energy could also provide a productive avenue for using agricultural and forestry wastes, besides plantations.
Environmental protection

By offsetting fossil fuel use and related emissions of nitrogen oxides, sulfur dioxides, and other pollutants, biomass energy will contribute to cleaner air and water. Furthermore, increased cultivation of carbonfixing plants will help mitigate greenhouse gas emissions that contribute to global.

It is estimated that around 2.4 billion people in the world depend primarily on biomass fuels to provide energy for cooking. Apart from cooking, biomass fuels are also used for process heating, steam generation, mechanical and shaft power, transport fuel and electricity production.

The examples of biomass that are commonly used as fuel includes:

    agricultural residues such as husks and stalks,
    vegetable oils and
    animal wastes.

In recent year’s , world has seen tremendous interest in biofuels, and a large research effort is focused on finding new biomass resources and processes for production of biofuels.

A variety of physical, thermo-chemical, chemical and biochemical processes are used for converting biomass into energy. In this chapter we will look into three modern biomass energy technologies (refer table 1.1) which can be applied in a decentralized manner and have proved to be useful in developing country context.
