Apart from solar and wind, MENA also has abundant biomass energy resources which have remained unexplored to a great extent. According to conservative estimates, the potential of biomass energy in the Euro Mediterranean region is about 400TWh per year. Around the region, pollution of the air and water from municipal, industrial and agricultural operations continues to grow.  The technological advancements in the biomass energy industry, coupled with the tremendous regional potential, promises to usher in a new era of energy as well as environmental security for the region. The major biomass producing countries are Egypt, Yemen, Iraq, Syria and Jordan. Traditionally, biomass energy has been widely used in rural areas for dom...

Image via Wikipedia Southeast Asia, with its abundant biomass resources, holds a strategic position in the global biomass energy atlas. There is immense potential of biopower in Southeast Asian countries due to plentiful supply of diverse forms of wastes such as agricultural residues, woody biomass, animal wastes, municipal solid waste, etc. The rapid economic growth and industrialization in the region has accelerated the drive to implement the latest waste-to-energy technologies in order to tap the unharnessed potential of biomass resources. The Southeast Asian region is a big producer of wood and agricultural products which, when processed in industries, produces large amounts of biomass residues. According to conservative estimates, the amount of biomass residues generated from sugar, rice and palm oil mills is more than 200-230 million tons per year which corresponds to cogeneration potential of 16-19 GW. In 2005, rice mills in the region produced 38 million tonnes of rice h...

First-generation biofuels (produced primarily from food crops such as grains, sugar beet and oil seeds) are limited in their ability to achieve targets for oil-product substitution, climate change mitigation, and economic growth. Their sustainable production is under scanner, as is the possibility of creating undue competition for land and water used for food and fibre production. The cumulative impacts of these concerns have increased the interest in developing biofuels produced from non-food biomass. Feedstocks from ligno-cellulosic materials include cereal straw, bagasse, forest residues, and purpose-grown energy crops such as vegetative grasses and short rotation forests. These second-generation biofuels could avoid many of the concerns facing first-generation biofuels and potentially offer greater cost reduction potential in the longer term. The largest potential feedstock for ethanol is lignocellulosic biomass, which includes materials such as agricultura...

Image via Wikipedia Renewable energy is growing rapidly in India. With an installed capacity of 13.2 GW, renewable energy sources (excluding large hydro) currently account for 9% of India’s overall power generation capacity. By 2012, the Indian government is planning to add an extra 14 GW of renewable sources. Grid Interactive Renewable Power in India Technology Potential (MW) Achievement (MW) Windpower 45,000 5,246 Small Hydro (<25MW) 15,000 537 Cogeneration/Bagasse 5,000 759 Biopower (Agro-residues and woody biomass from plantations 61,000 26 Waste-to-Energy 7,000 1 Solar PV Systems (4-7/kWh/km 2 /day) 20MW/km 2 2 Total 133,000 14,914 Source: Ministry of New and Renewable Energy, 2009 In its 10th Five Year Plan, the Indian government had set itself a target of adding 3.5 GW of renewable energy sources to the generation mix. In reality, however, nearly double that figure was achieved. In this period, more than 5.4 GW of wind energy was added to the ...

In India, the leading biofuel feedstock today is sugarcane molasses, which is processed to yield bioethanol that can be blended into gasoline (petrol). Sugarcane requires good land and large amounts of irrigation water, which are difficult for the poor to obtain. The bioethanol industry buys its molasses feedstock from the sugar factories. Sugar is the main objective of the sugarcane industry; molasses are simply a byproduct. As such, the unreliability of supply of molasses is a major constraint to biofuels development based on this feedstock. Even though India is an agrarian economy, the energy potential of agricultural residues has not been realized till now by policy-makers and masses. Most of the biomass wastes are inefficiently used for domestic purposes in absence of reliable and cheaper source of energy. The main crops produced in India are wheat, maize, rice, sorghum, sugarcane and barley. India is among the market leaders in the production of these crops and has tremendous ...
