Energy is an important development indicator, which provides vital inputs for survival and economic development. Energy supply and consumption is still in a traditional state in Nepal. At present, renewable energy generation capability of the country is still significantly very low due to technological and economical barriers. But the average efficiency of the renewable energy technologies is good in performance and also environmentally safe. Nepal is fully dependent on traditional energy sources such as biomass. For commercial purpose the country is reliant on imported fossil fuels like petrol, diesel, kerosene and LPG for running vehicles, stationary engines, boilers, cooking, lighting etc. Heavy dependence for energy on biomass resources has accelerated the depletion of natural resources and contributed to the degradation of natural environment. The country spends about 40 percent of it’s foreign currency reserve on the import of petroleum products. On the other hand, the country’s vast resource of renewable hydropower energy remains virtually unexploited.
Nepal needs to harness its vast hydropower potential and reduce its dependence on biomass in order to check the further degradation of the environment and reduce country’s dependence on fossil fuel based energy. The power so generated can be used for setting up clean energy based industries which will significantly contribute to the economic development of the country.
Nepal has huge potential of hydropower. The steep gradient perennial nature of the rivers of Nepal can provide the ideal conditions for the development of some of the world’s largest hydroelectric projects in Nepal. According to the current estimation Nepal has approximately 40,000 MW of economically feasible hydropower potential. However, only approximately 680 MW of hydropower has been able to develop till now and which do not meet the annual power demand. Many hydropower are under the construction and are not complete due to economic condition of our country. Due to this fact, completion period has been extended resulting in daily power cut which can extended to 14 hours a day. Although, Nepal is the second richest country in water resources all over the world, due to its economic and political conditions, proper use of these resources has been limited. Hence alternative source of energy may be useful for the development of the country. Thus, solar energy might be a good energy source in Nepal.
Solar power is little expensive for the initial installation but in long run it appears to be cheap. Solar panels are costlier only for first installation, after installation it does not required additional cost for the maintenance. It is necessary to keep panels relatively clean and making sure that the some objects don’t begin to overshadow them. The solar panels are very durable and it may...
