More people are reading about how to save energy and otherwise leave a smaller carbon footprint on the planet, and this year’sRadiant Heating Reporttakes a look at how the radiant/hydronic heating industry is attempting to do the same.

Anyone remember the first Earth Day, April 22, 1970? Yeah, me neither. A look back onTime.comnotes that some reached a quick decision about the true meaning of the day since it also marked the 100th birthday of Lenin.
