Survey of Renewable Energy systems along the Khumbu Trail en route from Lukla to Mount Everest PART 2


#5:  Himalaya Guest House:  Use Stove Heating.  Gas shower too expensive but they have extra gas shower nonetheless. 2 showers, one gas, one stove heating.  Stoves are ordered from Kathmandu, transported by plane to Lukla. Two porters are needed to transport stove from Lukla; one carries the stove, one carries the exhaust system.   Owner is Ten Jing.
Stove cost around 20,000 Rs in Kathmandu.  Transport cost 80 Rp/Kilo for 100 Kilo weight plus 2000 surcharge equals 10,000 Rp.  Cost of a gas bottle is 6,000 Rp, transferred from Ziri by Donkey.
Stove heat is mostly used for washing dishes.  Gas bottle can last for 2 seasons for a 15 minute shower and 1 month for cooking. Ten Jing can be reached at or Often works in Austria.


# 6:  Chumoa Guest House (Horse Rentals available).
2 15 W PV systems for kitchen lights and a hybrid wood burning stove/hot water system using two tanks (one for cold feed, one for hot water storage). Photos 6818, 6819:

#7:   Mini micro hydro installation at river vally below bridge;  traditional use of micro hydro for grain grinding.

#8: Munju  Macro Micro Hydro (Under construction while we were there).

#9:  Munju Guest House, 2 SHW systems, plus one 75 Wat PV system.  Sign says:  "Mrs. Dama Sherpa's Eco-Friendly Lodge: Fine home cooking with organic vegetables. Attached bathroom; solar hot showers."  On menu it says "order the same thing to save fuel".
Munju itself has at least 12 SHW systems and more than 3 100 Watt PV systems in evidence from trail.

#10 Mout Ka'lash Lodge, 2 Open vacuum tube SHW systems, electric backup heating elements not connected.  Has Parabolic Solar Cooker from

#11:  Momjo Cyber Cafe, an internet Cafe run on 3 PV panels, 1 70 W, 1 25 W and 1 10 W.  They charge 20 Rp (about 35/40 cents) per minute for internet, use 1 small 100 Amp Hour battery and a UPS system. they also have solar hot water.
Up on the Summit a home has a Solar Pro Hot Water System and there are 2 Sun Pro systems on one roof and one on another.

At the Sargarmatha National Park World Heritage Site a sign reads, "Tiwn Village Khumjung and Khunde (Green Valley): Thriving Sherpa Culture: Most Importantly you will experience how local Sherpa Culture has adapted new ways... villages blended into harmony with nature."
The growing use of solar electricity, solar hot water, micro hydro power, solar cookers and wind power certainly proves that this is the case.
