Via the ISEE list, this Time article about green technologies being adopted at Hindu temples and Ashrams. Indian religion has always had environmentalist undercurrents, often largely rhetorical, but it looks like we are now seeing the mainstream of the religion engaged in real environmentalist practice.

The Time piece asserts that 99% of Indians profess some faith. The major indigenous religions--Hinduism, Buddhism, Jainism and Sikhism--all have strong environmental tendencies. They make welcome allies.
