The Impact of Efficient Buildings

Investing in energy efficiency for residential and commercial buildings could reduce power system costs by $107 billion per year by 2050. These savings come from reducing the need for new energy infrastructure by enabling buildings to manage their energy use based on the availability of renewable sources.

Demand Flexibility

Buildings can adopt technologies that adjust electricity consumption in real time, responding to the availability of solar and wind power. Devices such as smart thermostats, electric water heaters, and responsive appliances can shift electricity usage away from peak periods—thereby lowering demand and avoiding costly infrastructure expansion.

Economic and Environmental Gains

Demand flexibility and energy efficiency not only reduce the need for new power plants and transmission lines, but also support greater integration of renewable energy. This leads to reduced reliance on fossil fuels and lower carbon emissions—helping to build a cleaner, more sustainable grid.

Challenges and Opportunities

Despite clear evidence of the benefits, large-scale adoption of efficient building solutions has been hampered by limited planning and reluctance to invest in non-traditional technologies. The report urges utilities and regulators to act swiftly and include these tools in their investment strategies.

Conclusion

Efficient and flexible buildings are essential to achieving a carbon-free power grid in a cost-effective way. By investing in these technologies now, we can cut costs, improve resilience, and accelerate the clean energy transition. It is crucial that policymakers and utilities seize this opportunity to enable a successful energy future.
