WindAction | The Forest And The Trees: Western Mass' solar siting problem

As Massachusetts tries to reach net-zero carbon emissions by 2050 — necessitating seven to 10 times its current solar capacity — contentious cases like Shutesbury illuminate a complex interplay of federal and state policy, grid infrastructure, and economics. Such factors can lead to seemingly counterintuitive proposals that threaten to pit activist against activist, like cutting down forestland to reduce the state’s carbon emissions.

Frontiers | Loading PCM Into Buildings Envelope to Decrease Heat Gain-Performing Transient Thermal Analysis on Nanofluid Filled Solar System

The high share of buildings in energy consumption and carbon dioxide emission has led researchers to seek techniques to reduce energy consumption in this sector. In this study, considering a hot and arid climate region, the wall's heat gain was investigated. To reduce energy demand, three techniques of adding PCM, combining absorption chiller with a solar system and dispersing nanoparticles were used and the results were evaluated transiently. In July, the addition of PCM to the building's walls reduced the heat exchange between interior and exterior spaces up to 21%. To cool the interior spaces, the combination of absorption chiller + fan coil was used and several flat plate collectors were integrated with it to reduce energy demand. By collecting energy in solar collectors and using a stratified tank, energy consumption in the generator section was reduced by 450 kWh. Nanoparticles were used to improve the solar system performance and it was found that loading ZnO and Al2O3 n
