Passive solar heating, if adopted can become an economical and practical solution to heat up Himachal’s oldest districts.
An interrupted power supply is a task in remote Himalayan villages during winters. This is the time when the people need the heating gadgets the most. 
Replica of Sonam Wangchuk ’s passive solar heating model which is functional in Ladakh can help Himachal Pradesh. It is a self-sustaining modal which works by trapping the sun’s heat.
This technique allows the insulated mud houses to remain warm and lighted in the coldest days.
By using this technique people can stay comfortably warm without burning coal or dry wood during the winter months.
Snow segregates many remote parts of Himachal during winters. The dry wood and coal burnt to keep homes warm during this time of the year contributes to the toxins into the pure air of the green state. When coal which is a fossil fuel is burnt, it releases carbon dioxide in the air. It is a greenhouse gas which further traps the heat from the sun.
The Himalayan region is home to many glaciers. The rise in temperatures here might not show an immediate effect but the long term effects will choke the existence. Therefore, passive solar heating can rescue the environment and comfort the lives in the remote areas of Himachal.
This technology works on the principal design which allows the windows, walls and the floor to distribute and reflect the solar heat stored in the winters while rejecting it during the summers.
The passive solar heating system is supported by huge plastic as well as glass windows. The mud walls are kept insulated by filling them up with waste paper and dry grass.
In Ladakh, they have even managed to keep the streams from freezing in peak winters by using this technique.
The low-cost passive solar heating systems targets to capture the sun’s heat inside the building’s elements. This is done to release that heat during periods when the sun is absent. It further maintains comfortable room temperature. It is a cost-effective solution to comfort the remote villages of Himachal.]]>
