Everybody’s favorite gigantic furniture store filled with flat-packed boxes is getting into solar panels. Cheap ones, too. Ikea is apparently getting ready to pump $75 million into "as many as ten companies in five different areas: solar technology, energy conservation, water saving products, alternative lighting, and new product materials,” according to TreeHugger. The goal of Ikea’s solar initiative is to be selling the “cheapest, best” photovoltaic roof panels to its stores within the next four years.
