The Green Oscars

The Ashden Awards for Sustainable Energy are presented every year to renewable projects in UK and developing countries in the world which aim at protecting the environment and improving the quality of life. The Ashden Awards are also called the Green Oscars. Read More

This year, projects BIOTECH from Kerala, SKG Sangha from Karnataka have won the awards under Biogas category. This year's 'Outstanding award', awarded to a past winner whose work has accelerated since winning an award has been given to Bangalore based Selco.

SKG Sangha has radically improved the lives of thousands of rural families in Karnataka, by supplying them with both dung based biogas plants for cooking and a specially designed unit that turns the slurry from the biogas plant into high quality fertiliser. It provides a cheap, reliable source of energy, reduces indoor air pollution and eases pressure on forest resources. The units supplied by SKG Sangha produce fertiliser simply by combining the slurry with straw and leaves and then adding worms which re-digest the mixture to produce vermicompost. SKG Sangha has installed over 43,000 biogas plants in the state of Karnataka alone.

The SKG Sangha's plant can be easily installed in rual areas where dung is readily available. We do have this plant installed at our native village. The plant needs no major maintainence. The gas produces highly bluish flame making it better than the LPG!

BIOTECH has succeeded in tackling the problem of the dumping of food waste in the streets of Kerala through the installation of biogas plants that use the food waste to produce gas for cooking and, in some cases, electricity for lighting; the residue serves as a fertiliser. To date BIOTECH has built and installed an impressive 12,000 domestic plants (160 of which also use human waste from latrines to avoid contamination of ground water), 220 institutional plants and 17 municipal plants that use waste from markets to power generators.


The BIOTECH Project is really boom for the urban areas. It can be easily installed in every house hold in cities as having a underground small plant is feasible. This also results in proper disposal of organic wastes, also reduces the pressure on under ground drainage.

Selco, based in Bangalore, provides its solar photovoltaic, electricity generating technology to families through microfinance, which means underwriting the cost for poor families. The price of a Selco solar home system is between US$275 and US$325 and it uses solar power to charge batteries during the day so lights and other appliances can run off them during dark hours.


With long power cuts in rural areas, Selco's solar systems have become a saviour of the rural people, also easing the pressure to build more power plants.

Rural India is making great progress in the field of sustainable energy by harnessing Solar energy and the bio-wastes. Thanks to Government's encouragement and sky rocketing electricity bills, people in urban India are going for solar water heaters. Much research needs to be done in the field of harnessing energy from the huge amount of wastes produced by the cities. Making Rain water harvesting and a small bio-gas plant mandatory in every house hold in cities makes a good start.
