“The point of the chart is simple: Some energy efficiency measures have a net cost and require fairly careful analysis to decide if they’re worthwhile. Those things are shown on the right side of the chart. But there are lots of efficiency measures that not only reduce greenhouse gas emissions but produce net cost savings at the same time. These are the low-hanging fruit of climate change, otherwise known as “no-brainers.” There are tremendous savings out there for the taking.”
