Many states have become concerned with ensuring that all segments of society, including people with low and moderate incomes, can benefit from solar and other forms of clean energy. Low and moderate income (LMI) residents often face particular barriers to using or benefiting from clean energy, including, among others, difficulties getting financing, frequent changes of address, language barriers, and the reluctance of some contractors to serve the low-income market. CESA is working with states to develop and implement LMI solar strategies. Learn more…
