Previous call to my MAMA

I have been always fond of renewable energy.  I always try to figure out that are we doing this right or there are changes  of further improvement ...?

So out of this curiosity I called my mama to get knowledge regarding solar panels who has great experience of dealing with electronics and electric devices. He has already 4 panels. He answered my questions as:
Price : 10 k max per solar plate 

Power: 9A per solar plate 

Warranty : 25 years!! 

What he suggested  for my family  is that two solar panels  will be more than enough for any season. That means initial investment of 20 k. Because we already have Battery-inverter . He told that we can easily  run 2 fans,  a motor for pumping our water to roof top, a PC. A normal household appliance usually works on 5A. So there is enough power generated by these two solar panels to run our household appliances in the day with the inverter charging the battery simultaneously, which can be used in night to run the fans and lit the bulb or CFL.  

 So on the average one can easily  save 300 rs per month on the average from electricity bill .  So at this minimum rate in 5-6 years your investment will be recovered and you will be helping in reducing your carbon footprint as well as your country's.  This saving of electricity will save us from

   1. Burning our money or creating  a hole in our pocket 

   2. Burning coal which can lead us to following benefits 

            2a. Reduction of carbon dioxide 

            2b. Help us making save our forest which usually get destroyed in the process of coal digging. 

   3. Less dependence on government 

   4. Global warming 

   5. Fear of electricity crisis in chilling summer (April to july)

so I have some questions in my mind after the call 

•  Why government is not advertising or promoting this green thing /or any green technology?
• Why government is not trying to solve our problems permanently 
• Why can't they make a necessary rule to implement this who can easily afford this setup. 
• Why government is feared to take hard steps, just because that they may loose votes? They may loose governance.
