New real-world case studies show the energy-saving potential in the world's buildings, vehicles, and factories is severalfold larger and cheaper than normally assumed. Few business leaders have noticed, but the emerging integrative-design efficiency revolution holds supply-side investments at risk.

Three guesses: is this blog about a new, cheaper renewable technology? a cheaper, safer nuclear fission or fusion technology? a new technology to extract more fossil fuel at lower cost?

None of the above. It’s about neither energy supply nor new technology. It’s about a more important but far less familiar story: how smarter design can better apply existing technologies to create radical energy efficiency at far lower cost. That gamechanging linkup creates a potential new compet­i­tor to all forms of energy supply. Every year, it could save the world many trillions of dollars’ worth of fossil fuels more than it costs. Indeed, some savings are better than free: they can actually make buildings, vehicles, and factories cheaper to construct.
