Actually the real solution is managing consumption.
People need to stop using multiple split A/Cs in their rooms and UPS.
All the electricity wires should go underground, so it will look cleaner, safer, and theft free.
Say No to CNG Gas in cars. Don't prioritize it. We were a country with so much gas that we once offered offered to export. We are a population of almost 200 million people, and with such resources, it needs to be managed well. The realistic option is to increase the cost so people rely on public transportation, other than personal cars.
Last but not least, we need to change the style of building infrastructure, particularly homes. They need to use traditional and or materials that are environment friendly. With the present concrete and no proper insulation we are using, it is proven that it makes the homes warmer in the summer and colder in the winter. As a result, we burn more electricity in the summer and gas in the winter.
