Solar Powered Trains

1) Sustainability problem: energy


  • Indian Railways are installing solar panels on 250 local trains to reduce fuel costs and lower emissions. The energy will among other things be used to power lights and fans on the trains. The technology will help advance India’s renewable energy program, especially because the trains mainly will run in areas where there are no electrified tracks.
  • The Indian government has planned that 7000 railway stations will use solar power. By doing this, 25% of the Indian Railways can energy demands can potentially be covered by renewable energy sources by the year 2025.
  • Furthermore, India has stopped the construction of 14 new coal-fired power stations due to the favorable implementation of this technology. As India is such a large market, experts say that this can cause a large shift in the global energy markets.



  • Railway companies
  • Solar panel companies
  • Energy companies




  1. Incentivize railway companies to make this shift in energy policy
  2. Mount solar panels on train cars
  3. Provide proper maintenance of the solar panels so that they are always working optimally

My comment on another article

“This is a great start to making cities greener. As more and more people establish themselves in the larger cities there needs to be a shift in how people transport themselves from point A to B. Implementing bicycles as a preferred option in the city will also reap huge health benefits for the population as a whole. Health issues are increasing at almost the same pace that large cities are expanding, so this is a solution that can kill two birds with one stone, and help solve both issues at once.
