GEOTHERMAL ENERGY
Geothermal energy is energy obtained by
tapping the heat of the earth itself
![Page 14: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ... Other Sources of Energy](https://reader031.vdocuments.mx/reader031/viewer/2022021418/5aaf69097f8b9a59478d49c9/html5/thumbnails/14.jpg)
GRID ENERGY STORAGE
Grid energy storage :
1)Electrical energy is stored at times when production exceeds consumption .
2)The stores are used at times when consumption exceeds production.
3)In this way, electricity production need not be changed for momentary consumption ..
![Page 15: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ... Other Sources of Energy](https://reader031.vdocuments.mx/reader031/viewer/2022021418/5aaf69097f8b9a59478d49c9/html5/thumbnails/15.jpg)
FOCUS ON Renewable
• Renewable are not firm power and are not for capacity addition, (unless their penetration level goes above 20%.)
• They can be energy adders, and take care of peak demand and load management.
• Renewable have a distinct advantage if 60 to seventy percent of power can be locally utilized, otherwise cost of transmission could be very high. Proper load generation balance could lead to energy security at micro level.
![Page 16: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ... Other Sources of Energy](https://reader031.vdocuments.mx/reader031/viewer/2022021418/5aaf69097f8b9a59478d49c9/html5/thumbnails/16.jpg)
Mission without Vision
• Distorted growth under too many policy frame works, government clearances, and controls.
• Renewables do not enjoy a level playing ground.
• States are not taken into confidence as a partner in the National mission driven programs
• A lesson to be learnt from China and Japan where mass production and commercialization drives the market and R&D.
![Page 17: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ... Other Sources of Energy](https://reader031.vdocuments.mx/reader031/viewer/2022021418/5aaf69097f8b9a59478d49c9/html5/thumbnails/17.jpg)
Responsibility of the supplier
• Renewable energy has lower capacity factor and are seasonal.
• Maintenance after commissioning in in- accessible areas remains as the biggest hurdle.
• The supplier should have a responsibility to maintain equipments and update it for longer periods and be a partner from the beginning.
• Multinational Suppliers have different business interest
• If the technology is for the consumers, it has to be consumer friendly, meaning high availability and reliability
• It should be maintenance free
![Page 18: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ... Other Sources of Energy](https://reader031.vdocuments.mx/reader031/viewer/2022021418/5aaf69097f8b9a59478d49c9/html5/thumbnails/18.jpg)
Ensure success, Can’t afford to fail
• The immediate attention must go to a high penetration level of wind, solar and biomass
• Govt. should plan load growth around wind mill zones to make wind power effective.
• Some electricity consumption must go Solar in urban area as a mandatory practice.
• Concept of buying solar certificates must percolate to consumer level: Either they go solar or support solar
• Rain harvesting, solar heating must be conditional to accepting building plan
![Page 19: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ...

Administrative support to Entrepreneurs
• Jawaharlal Nehru solar mission has attracted investors
• Govt. must identify barren lands.
• Grid connectivity should be assured by DISCOMS or GRIDCO
• Each state must fulfill his quota of commitment
• The fear is that the big players will corner the business, big Govt. subsidy would go to big houses ,
• Can consumer cooperatives take control?
• Can consumer societies own their generating stations?

DECENTRALIZATION OF POWER
• Whether generation , transmission and Distribution can be managed by any other body?
• Does consumer have a choice?
• Are people involved in the reform process?
• How can we decentralize?
• Panchayats to work as institution of self Government?
• Wide penetration of Renewable Energy
• Parallel Development of rural economy
![Page 21: Non conventional energy sources and research interestssilicon.ac.in/nwet2015/materials/ppt/NON... · Non conventional energy sources and research interests ...

Issues for Discussion ..
• Is it not time that we have a simple, transparent system of pricing which is based on following postulates
– Let market forces determine prices
– No discrimination between different producers, on ownership or any other criteria (If subsidy disbursal is necessary, should we follow example in Fertliser sector of treating private and public sectors alike)
– Subsidise a consumer, rather than than the product. Let economic logic dictate policy
– Specific duties or levies that are transparent and simple
– Target towards - One India, One Market and One rate of tax for petroleum products - and look for other sources of revenue generation

A New social order with Renewable Energy
• Significant contribution of small decentralized generation shall bring a cultural and economic change in ‘rural India’
• Small contributions from a large population can be substantial at the National level
• Renewable energy can be an R&D challenge for next generation students and scientists
• Needs to be driven like the green revolution or the white revolution
