Although Solar energy has been often hailed as a green source of energy, shortcomings in conventional silicon based solar cells and the environmental damage caused during mining and manufacturing of such cells raises questions on the green nature of the energy. In a breakthrough, scientists have developed organic solar cells, developed from indigenously developed discotic liquid crystal, that could provide an alternative.
Coastal erosion and the proliferation of seawalls, exacerbated by climate change and human activity, are rapidly eliminating critical nesting habitats for sea turtles along the Karnataka coast.
