In its profile of Sun Microsystem co-founder Vinod Khosla, the New York Times notes an increased interest among technology entrepreneurs to fund social and environmental impact through investment.

"An Indian transplant to Silicon Valley, Mr. Khosla plans to start a venture capital fund to invest in companies that focus on the poor in India, Africa and elsewhere by providing services like health, energy and education.

"By backing businesses that provide education loans or distribute solar panels in villages, he says, he wants to show that commercial entities can better help people in poverty than most nonprofit charitable organizations."
