Name a renewable energy technology commonly integrated into green buildings.

• A. Photovoltaic (solar PV) panels
• B. Coal-fired boilers
• C. Diesel generators
• D. Nuclear reactors

Answer: (A)

Solar photovoltaic panels are the best fit because they provide on-site, renewable electricity by converting sunlight directly into power. This directly supports a building’s goal of reducing energy from fossil fuels, lowering emissions, and often enabling net-zero energy performance when paired with efficient design and storage. Solar PV can be hidden in or on building surfaces (rooftops or facades), making it a natural, scalable integration for green buildings.

Coal-fired boilers, diesel generators, and nuclear reactors aren’t aligned with typical green-building goals. They rely on nonrenewable energy sources or complex, large-scale systems and come with higher emissions, safety, and cost considerations for individual buildings.
