Many Americans are facing tough choices between air conditioning and food due to a predicted 8% rise in household utility costs this summer, according to the National Energy Assistance Directors Association. Experts say policy changes in Congress are needed to boost assistance for those struggling most with utility expenses. Lower-income households spend a large portion of their budget on electricity costs which are rising due to fuel prices and transmission fees. Assistance programs that help offset costs need more funding to help vulnerable groups stay cool amid higher bills.
