    • It is critical to understand the difference between what is Possible, andwhat is Feasible
      www.eai.in
    • Energy Sources
      www.eai.in
    • Real Imperatives for Renewables
      • Fossil fuels becoming more scarce and costly
      • Governmental mandates on GHG emissions
      • Industry-wide consensus for sustainable practices
      • Consumer preference for green companies

    • Making Sense of Renewables
      • Geo Sense - Not all renewable sources make sense to all of us (ocean energy makes no sense to landlocked countries)
      • Time Sense - Some renewable energy sources are in their nascent stage (it could take 10 years to get fuel from algae)
      • Money Sense - Renewables need to make both ecological and financial sense (small wind is ecologically sound, but financially not)

    • Making Renewables A Reality for Your Business
      What
      …are the real benefits for us from renewables?
      Which
      …renewable sources are really appropriate for us?
      How much
      …do renewable energy sources really cost?
      How
      …can we really start off?

    • Whatare the real benefits for us from renewables?
      1
      www.eai.in
    • Real Benefits from Renewables
      • Distributed energy
      • Fuel security
      • Hedge against inflation
      • Setting yourself for a more sustainable future
      www.eai.in
    • Real “Costs” of Renewables
      • Intermittency & unreliability (solar PV and wind)
      • Not all are future proof in terms of feedstock (eg., biomass)
      • Technology risks (solar CSP)
      • High costs – solar, wave/tidal, 2nd/3rd gen biofuels

    • Renewable energy possibilities
      • Renewable power
      • Renewable heat (and cold)
      • Enhanced energy recovery
      www.eai.in
    • Renewable power
      • Solar PV
      • Thin films
      • Crystalline
      • Wind
      • Small wind
      • MW scale wind
      • Biomass
      • Gasification
      • Combustion
      • Organic Waste
      • Anaerobic digestion
      www.eai.in
    • Renewable heat and cold
      Renewable heat (and cold) can be obtained from:
      • Biomass gasification
      • Solar thermal
      • Anaerobic digestion
      www.eai.in
    • Enhanced energy recovery
      Enhanced energy recovery is possible through
      • Cogeneration (…trigeneration and perhaps, even quadgeneration)
      • Waste heat recovery
      www.eai.in
    • Technical feasibility of renewable sources for captive
      Depends on
      • Scale of operations
      • Availability of natural resources
      • Land availability
      www.eai.in
    • Scale of Operations

    • Availability of natural resources

    • Land availability

    • Suitability as a captive source
      www.eai.in
    • Attractive options for captive energy
      www.eai.in
    • How muchdo renewable sources really cost?

    • Real Costs
      www.eai.in
    • Costs – Highlights and summary
      • Wind, biomass power and anaerobic digestion based power are close to grid parity
      • Biomass power could cost much higher if no control on prices of biomass
      • Both solar PV and CSP cost more almost three times as much as grid power
      • Cost reductions with time are highest for solar PV and CSP, thus they could be cost-leaders in future.
      www.eai.in
    • Financial support mechanisms
      • Capital subsidies
      • Tax holidays
      • Accelerated depreciation
      • Soft loans
      www.eai.in
    • Other monetization possibilities
      Co-products and by-products
      Biomass gasification
      Charcoal
      Activated carbon
      Anaerobic digestion
      Nutrient laden effluent  Fertilizer
      Waste heat
      process heating + drying  cooling (trigeneration)  fuels (quadgeneration)
      Carbon credits
      Renewable energy certificates
      Avoiding cost of organic waste disposal

    • Howcan we really start off on renewables?

      www.eai.in
    • Way to go…
      Understand the scope of possibilities
      Shortlist the most appropriate for your business
      Test with a pilot
      Go live!
      www.eai.in
    • Reality check while starting off renewable projects
      Visit companies that have already implemented similar solutions
      Results from projects vary across companies and locations
      Most renewable energy projects have payback periods in excess of 3 years (solar > 7 years)
      Most renewable energy projects will require good amount of maintenance and repair operations
      www.eai.in
