"Energy efficiency is the most important climate solution for several reasons:
- It is by far the biggest resource.
- It is by far the cheapest, far cheaper than the current cost of unsustainable energy, so cheap that it helps pay for the other solutions.
- It is by far the fastest to deploy, without the transmission and siting issues that plague most other strategies.
- It is “renewable” — the efficiency potential never runs out.
"This post focuses on #1 — the tremendous size of the resource, especially here in the United States, the Saudi Arabia of wasted energy.
