What types of renewable energy sources can earn credits under EAc2?

EAc2, which stands for Renewable Energy Production, encourages the use of renewable energy sources to reduce environmental impacts and promote sustainability within a project. The correct choice indicating "all of the above" is valid because it encompasses a broad range of renewable energy sources, including geothermal, hydroelectric, solar, biomass, and wind energy.

Each of these energy types contributes to the reduction of greenhouse gas emissions and reliance on fossil fuels. By implementing any of these renewable energy solutions, projects can earn credits under LEED’s Energy and Atmosphere category. This encourages a holistic approach to energy production and use, aligning with the goals of LEED to promote environmentally friendly practices.

This inclusive stance on various renewable sources recognizes the diverse potentials across different regions and projects, allowing for flexibility in implementation according to local energy resources and technologies available. Each of the sources listed plays a role in fostering a more sustainable energy landscape.
