The world is changing fast — we are in the middle of a silent renewable energy revolution and builders need to understand these quiet but disruptive changes in order to ride the wave of change without being swamped by it. Production of renewable energy from wind and solar is growing as costs are falling. In most locations, it is less expensive for utilities to build new renewable plants than to build a coal-fired power plant and often it’s cheaper than natural gas. Homeowners are increasingly installing solar panels and batteries, and purchasing electric vehicles, as prices continue to decline. Innovations are in development that will speed progress to an all-electric, carbon-free, renewable energy-based economy. How will these innovations affect builders? How should builders prepare? Cheaper, More Efficient Solar Panels Current silicon-based solar panels have a maximum of 23% efficiency with a theoretical maximum of 30%. Perovskite-based panels have a current...
