They have made all kinds of investments in wind, solar, geothermal, etc. Some are to generate clean energy for their own needs, others are more akin to financing deals to help big wind and solar farms get built. In any case, it is very commendable work and if more big corporations had the long-term vision of Google, the world would definitely be in better shape.

The Ministry of Industry and Information Technology quietly published a list late Sunday of 2,087 steel mills, cement works and other energy-intensive factories required to close by Sept. 30.
