All of our electricity (which is very little as most of our efforts go to efficiency and electricity saving) comes from a micro-hydro turbine and photovoltaic panels. Energy is gathered together in a 24V battery bank to power all of EcoCamp’s refrigerators, lighting, electrical appliances, stereos etc. Propane gas is only used to heat water and superior domes. A pilot scheme to heat shower water with solar energy is in motion.
Water from the river enters the micro-hydro turbine at 5 litres per second with a net pressure of 38 meters delivering a steady power of 800 Watts. An inverter is used to switch from the 24V DC in the battery bank to 220 AC, the standard voltage in Chile. An array of 1700 Watt photovoltaic panels - also connected to the battery bank - collect the extra energy needed at Ecocamp.
Electricity is limited and only available to guests for charging camera batteries and laptops, not using hairdryers or electric razors. Solar energy is very efficient in summer when Patagonia receives up to 17 hours of sunlight daily.
Domes have skylight windows so natural light and heat can be utilized. This not only allows guests to follow natural light patterns but saves electricity, leaving us confident that our renewable energy sources are sufficient and fossil fuels are not needed. Suite domes have a wood stove for warmth, recycling dead wood from the park and avoiding the need to use diesel.
