The modern green housing movement in the US can be traced back to the 1970s, when the country was facing an energy crisis and growing concern over the negative impact of traditional building practices on the environment. The first modern green building, the Hopkins House, was constructed in 1982 using salvaged materials, passive solar design, and other sustainable building practices. Today, green housing is widely implemented in the US due to the increasing need to reduce carbon emissions and combat climate change, financial incentives for building green, and the availability of sustainable building materials and advances in technology and design. Building green is now more important than ever, and the future looks bright for sustainable, energy-efficient homes in the US.
