Elsie Calayton's family received a d.light solar lamp to help them recover from Typhoon Haiyan

Blessed with light »

On 8 November 2013 Typhoon Haiyan struck the Philippines, causing massive damage across many islands. Last month, the Yason Farm School, one of Kopernik's local partners in the Philippines, distributed emergency relief supplies in the San Mariano area of Oriental Mindoro. The Peace and Equity Foundation (PEF) donated money towards the purchase of 48 S10 d.light solar lamps and three S250 d.lights from the school, to help the people who were most severely affected by the disaster.

The Rubaya family relies on their d.lights to farm at night and charge mobile phones

Families, Farms and Fellows in the Philippines »

I recently arrived in the Philippines to support two of Kopernik’s ongoing solar light projects here. In an unexpected turn, I will also be exploring what solar lights mean for the emergency relief and recovery efforts in the aftermath of Typhoon Haiyan. I am based in San Mariano, Roxas, Oriental Mindoro, which was spared from much of the damage, but surrounding communities to the north were not as lucky. They are currently still without electricity and clean water.

Thanks to the solar lantern, Fatmawati can now afford milk for her young daughter

Less kerosene, more milk »

I've been conducting my impact assessment of d.light S250 solar lanterns in Galinggang for six weeks now. When we think about solar lanterns, we naturally think about how the light that they produce can help the people in the village. The purpose of a solar lantern is to emit light. Therefore the light produced is the direct benefit of purchasing the lantern. But is there more than that?

Teaching English to ninth graders in Kalimantan

Britney who? »

I arrived in Galinggang with three other people: a lecturer and two Masters students from Keio University in Japan. As their guide and interpreter, I had to speak English during my first days in Galinggang. This led to a chain of events that started with a knock on the door. The principal of Galinggang’s middle school and her husband came quite late at night to ask me to teach English to the students. The school, SMP Negeri 2 Kamipang, has no English teacher this academic year.

He knows the importance of education, and always gives 110 percent to every task and homework given to him each day. He is a true embodiment of our young generation, who are determined to forge a different path to their parents. Wanting a better life, higher education, bigger dreams. Today, Rasid needs to work on a maths group paper.
