While making a visit our capital city Kathmandu during my holidays some construction work was going on in the road. The workers were taking out the old bulbs, doing something on the pole, some were digging in the road as well. 

Next day while passing through the same road, there was some changes in street light and some slight modification in road as well. All those street lights were changed if or solar powered light, trees were grown in the road ( making avenue and boulevard). This made me really happy to see such eco friendly changes in the city. This might be common in developed countries but it's a new and we coming practises in our cities area.

Solar energy needs to be promoted specially in the cities like kathmandu where we have sunshine almost everyday.  If municipality acts as the pioneer for this then implementation of such eco friendly energy use becomes easy. 

And of course walking in the road where trees are planted provide us different sense of pleasure part from providing us with oxygen and intaking the harmful toxic gases. Trees adds beauty to the road and makes environment so delightful. 

Solar power should be popularised in towns and cities as well( in some rural areas where transmission lines are difficult to establish solar energy was made chief source of energy for daily activities. This got instant hit in such regions).  Not only limiting to the street lights, solar energy should be used in home appliance as well. 

This activity of municipality is appreciable. Let's all of us plant tree in our home as well and use solar power. For sun is the perpetual source of energy.
