    The villages of Momai and Bugolyak are next to each other and hidden in the remote (偏远的) high mountains of Tajikistan. Life in the village has been peaceful. There are about 40 families in Momai and 18 in Bugolyak. The villagers live on crops and farm animals. Their connection to the outside world is a hilly road. The villages have no electricity. The villagers use oil for lighting.

It seems that many years ago the power company considered building a power line to the village. However, it was put off or maybe given up because of the high construction(建设) cost and low return for the investment(投资).

Thankfully, Asian Development Bank decided to carry out solar power system projects in Tajikistan at that time. At first, the progress was rather slow. It took them two years to complete studies.The real project started in Jan. 2016 and was finally completed in late 2017. The poor road conditions in the village also made it difficult to bring materials.

The villagers are very happy about the solar power systems. They can watch television at their homes for the first time. Children can now see the outside world without going out. Batteries provide power during the night or when it is raining. In addition, a solar power system has been set up in the school and it can send water to homes.

Mr. Karimov, a volunteer, taught villagers how to keep solar power systems and use electricity safely. Although this project has been a success, there are many people who still have no electricity to use. Finding money for such projects is not easy. However, there are many people like Mr. Karimov who are working hard to create a better and greener future.
