INTRODUCTION

We are largely dependent on fossil fuels for our energy needs. My idea is to reduce our dependence.

An analysis of our energy sector and our expenditure. My presentation is focused on INDIAN scenario. My Idea

is centralized on our country’s renewable energy(mostly focused on bio mass) potential and how we are going to tap it to fulfil present day’s energy needs without disrupting the growing energy needs.

INTRODUCTION

The actual renewable energy scenario of a sub urban area like ROORKEE-HARIDWAR by using a survey which is done by us (by the help of patanjali yogya pith) and then generalizing the survey result.

Trying to present a green energy model that can be applied on Roorkee-Haridwar.

One modification in Bio-gas plant is suggested by us to harness both gaseous fuel and electricity.

Utilization of barren land and west land. Solutions to the concerns and problems raised in the

problem statement.

Indian Energy Scenario

India a growing economy, world’s 2nd most populous country and also 2nd in population density. Energy demand is rising with high population growth and modernisation of our lifestyles, higher will be electrification rates and a rapidly growing economy. Annual growth in energy demand has reached 8% recently. With GDP expected to grow by 7.5% and our energy demand expected to nearly double by 2030. Our total energy production is 150000 MW and we are in power deficit of around 10%.

Indian Energy Scenario

INDIA’S POWER SCENARIO

• Total Installed Capacity 1,50,323 MW• Per-capita Power Consumption 704 kWh• Power Generation 2.4% of the World• Power Consumption 3.3% of the World

Energy Scenario

BIOMASS POWER SCENARIO

• India has a biomass availability of 150 million MT per annum which gives us a potential to install 16,000MW of biomass based power plants. But only 600MW is installed and another 600MW is under implementation. To realise this huge potential we need an investment of Rs.1,00,000 crore. Some reasons for lack of investments in Biomass sector are:

• It costs around Rs.6cr/MW for a Biomass plant whereas a thermal plant requires only about 4.5cr/MW.

• Availability of Biomass fuel with high calorific value (> 4000kcal/kg)

Driving factors of Biomass industry in India

• A huge untapped potential• Environment friendly• Reduce our power dependency on other country• Ability to have small, kW scale power production• Suitable to fulfil rural energy demand• Efficient utilization of renewable biological sources• Low Cost Resource• In India it is also location independent

POTENTIAL BIOMASS FUELS

• Crop residue and farm wastes - The straw of cereals and pulses, stalks and seed coats of oil seeds, stalks etc

• Industrial wastes - These wastes include wastes from paper mills, chemical mills etc.

• Industrial wastes • Forest wastes • Logging residues • Residues of wood product industries• Residues from pulp and paper industries • Municipal solid wastes

POTENTIAL BIOMASS FUELS

Roorkee – Haridwar scenario

Being in a area of Roorkee-Haridwar, in the foot-step of Himalayas, in the bank of river Ganga. It is a highly fertile land with good crop yield and also the huge crop residue. Haridwar being a small city of having religious importance, It has a huge population of milk animal especially cows and buffaloes. It also has a large forest body. So suitable for settling a Bio-gas plant but here I would rather say gober-gas plant, the cow dung which contain huge amount of methane and manure too

Gobar -gas

Ways to generate electricity and fuel gas

Different questions raised

• Unpredictability and inconsistency – Not a case in Indian scenario, as show earlier we produce huge amount of biomass daily.

• Dependency on location – We have almost uniform production of Biomass but states like M.P , U.P , Haryana , Panjab , Rajasthan are the leaders but you can see three of them are big states.

• Maintenance – The raw material are actually west to us are very cheap the remaining running cost is low with respect to other, It also provide employment to the rural people.

• Lack of awareness – yes this is the area we need to work and responsibility of intellectual society .

• Practicality – actually many bio-gas plants are running successfully in our country. Which clearly indicate it is well feasible.

• High cost – the increasing cost of fossil fuel because of crisis and environmental consideration, It is feasible. One analysis is enclosed.

Cost analysis

Investment• India and Germany have signed a Rs.140 crore deal to install 7

Biomass projects in India. • During the 11th Plan period, the Government of India aims to add

500MW capacity • through biomass in many states, including Maharashtra, Uttar

Pradesh, Tamil Nadu and Karnataka. • All Green, a leading renewable energy developer in India, plans to

raise US$100• Million to set up ten 6.5MW biomass-to-energy projects across India

over three years. The first three, projected across India.• to go on-stream by March 2010, will be in karnataka,Tamil Nadu and

Madhya Pradesh. • French nuclear power specialist Areva and US-based Astonfield

Renewable• Resources are teaming up to invest about €100m ($142bn) in

biomass power plants

Modification

Piezoelectric Systems

• It is made up of piezoceramic materials (these days some nano-materials also serve the cause).When stress is applied on these materials, it results into electric charge separation and also high potential difference also appear across the material depending on the type of material used .For example- lead zirconate titanate crystals etc.

Land analysis of our area

Utilization

• The welspun energy company has set up 151 megawatt’ solar power plant covering up 800 acres. This mega solar plant was started off eight months earlier than its presumed time at the cost of Rs. 855 crores. With the help of this plant, about 6, 24,000 houses will avail the energy. The welspun company also has it’s one of the industrial units in Kutch of Gujarat.

• It is 0.18875 Mw per acre.• The efficiency of solar cell are nearly about 20%• It can be increased significantly by using light trapping

and antireflective coating yet under development.
