Types of Sustainable Models

• 3 Legged stool model• 3 overlapping circles model• 3 nested dependencies model

3legged sustainability model

3 overlapping circles model

3 nested dependencies model

Role of sustainability model in development

• To solve the problems of shortage of food• To solve short lifespan problem and ecological

problems.• To solve the problems of autocratic rule.

ENVIRONMENTAL IMPACT OF ELECTRICITY GENERATION & TRANSMISSION

Coal Production

• In the process of coal production – coal mining has long term and short term effects on land.

• The environmental impact of mining includes erosion, formation of skinholes, loss of biodiversity, contamination of soil, groundwater and surface water by chemicals for mining processes.

• Eg. Giant OK Tedi Mine in Papua New Guinea

Fossil Fuels• Fossil fuels constitute a

significant repository of carbon buried deep underground. Burning those results in the conversation of CO2 & is then released in the air.

• This enhances the greenhouse effect and contributes to global warming

Nuclear Power plants• Abnormal operation may

result in release of radioactive material on scales ranging from minor to severe although.

• A long term issue is decommissioning nuclear power plant.

Hydropower

• The use of hydro power can have both positive and negative impact on environment.

• Dam failure can lead to catastrophic floods.• It causes low dissolved oxygen levels in the

water this is very harmful to riverbank habitats.

SUSTAINABLE MODEL IN INDIAHUSK POWER SYSTEMS

• HPS provides end to end renewable energy solutions by installing 25kw to 100kw mini power plant and then wiring villages and hamlets of up to 4000 inhabitants to deliver electricity on pay per use basis.

• Impact on community development.• Recycling by products

• Distributed product manufacturing• Proto Village• Carbon offset
