Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

Nuclear or Solar ? Choice is clear

 Nuclear or Solar ? Choice is clear


=============================================
I think it would be far better for India to spend this money on grid-scale Solar power , rather than on Nuclear plants

Following tabulation supports my argument . I request Energy Experts to confirm ( or disprove ) these figures :

Parameter :

Surya-Ghar Scheme / Nuclear Power Scheme
======================================

Capacity Envisaged ( GW ) :

30 GW ( 3 Kw x 1 crore families ) / / 11 GW
=====================================

Investment Estimate ( Rs ) :

120,000 cr ( @ Rs 1.2 L / 3 Kw ) / / 1,56,200 cr
======================================

Investment per GW ( Rs ) :

4,000 cr // 14,200 cr
=====================================

Expected Completion Time ( Yrs ) :

4 // 16 ( Target completion by 2040 )
=====================================

% cost borne by the Govt :

60 % // NIL
======================================

% cost borne by Installer :

40 % // 100 %
=================================

Est. generation cost ( Rs / kwh ) :

FREE // 15 ( latest Jaitapur plant )
================================

No of homes to be served :

1 crore // 1 lakh
========================================

Import Content :

Nil // Enriched Uranium ?
==================================

Safety Record :

Excellent // Excellent - but around the World, Nuclear plants are closing down
==================================

International Compliances Required :

None // Several ( including inspection )
===================================

Supply of Fuel :

Plenty of Sun-shine (300 days/yr) // Enriched Uranium in short supply
============================

Reduction in GHG per year ( after full implementation of 1 crore ) :

210,240,000 tons // ?
==========================

Earnings @ $ 10 / carbon credit :

$ 210,240,0000 ( Rs 17430 cr / year  = 14.5 % on investment of Rs 1.2 lakh*crore ) // ?
==============================

Adverse Factors :

Multi-story City buildings have roof area for only 10 % of the tenants of a building( for 300 sq ft / 3 Kw ) //

# Very high investment / GW
# Very high price / Kwh
# Long time to install
#  Opposition from local people

#  Reluctance of Funding Agencies

=============================
