Lake Toba, a 75,000 year old crater and one of the most beautiful places on earth, suffers from severe environmental degradation. A central reason is that the outflow from the lake is used to generate electricity. The outflow has been increased so that now more water flows out than flows into the lake and there has been a consequent rapid and disastrous drop in the water level.

In September 2013, I went to the region to return elements of cultural heritage to the Batak people living near the Lake. I chose to conduct the project by boat because of the lake’s tremendous proportions in local mythology and because of the ease and romance of using it. Our boat was a simple, local market-cum-tourist boat and we had essentially no electricity. I brought along Wakawaka lights for my repatriation team, four of them young local people, to provide us with light and enough power to keep our mobile phones running

to his Wakawaka light.
and, even more importantly, to demonstrate the production and use of solar electricity to the people with whom we came in contact. The lake needs a fix and quickly!

The lights proved indispensable. We sunned them carefully on the deck every day and then used them for our phones and for light.

Everybody who saw them and received our explanation immediately recognized their functionality. Our auto chauffeur (Pak Jerry) perceived that they were perfect for his needs, as did the captain of the boat (Amang Siregar). The local regent (Pak Mangindar Simbolon) wanted them for remote areas that don’t yet have electrical supply. And of course there was an immediate recognition that sunlight is cheaper than electricity.
The journey was about repatriation of cultural elements from the past, but not just about that. It was about a future in which the culture and also the environment would recover their health. Wakawaka generated a kind of Eureka reaction! Solar power is one viable and important choice in a region that needs a panoply of changes to make a better future!
