13. Time Sense - Some renewable energy sources are in their nascent stage (it could take 10 years to get fuel from algae)

14. Money Sense - Renewables need to make both ecological and financial sense (small wind is ecologically sound, but financially not)www.eai.in

15. 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? 1 2 3 4 www.eai.in

16. Whatare the real benefits for us from renewables? 1 www.eai.in

18. Fuel security

19. Hedge against inflation

20. Setting yourself for a more sustainable futurewww.eai.in

22. Not all are future proof in terms of feedstock (eg., biomass)

23. Technology risks (solar CSP)

51. Suitability as a captive source www.eai.in

52. Attractive options for captive energy www.eai.in

53. How muchdo renewable sources really cost? 3 www.eai.in

54. Real Costs www.eai.in

56. Biomass power could cost much higher if no control on prices of biomass

57. Both solar PV and CSP cost more almost three times as much as grid power

58. Cost reductions with time are highest for solar PV and CSP, thus they could be cost-leaders in future.www.eai.in

60. Tax holidays

61. Accelerated depreciation

62. Soft loanswww.eai.in

63. 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 www.eai.in

64. Howcan we really start off on renewables? 4 www.eai.in

65. Way to go… Understand the scope of possibilities Shortlist the most appropriate for your business Test with a pilot Go live! www.eai.in

66. 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

67. About EAI Dedicated focus on renewable energy and cleantech for India Diversification, feasibility studies, market entry strategy, business intelligence Work with corporates on making their factories use more renewables Founded by professionals from IITs and IIMs Based out of Chennai More from www.eai.in – see also our club, forum, mailing list… www.eai.in
