What is one criticism of the government's support for energy-efficiency improvements in Michigan?
The total cost of home improvements was more than twice as much on average as the savings they would produce.
By trying to make improvements to so many homes, the government ended up doing poor-quality work that reduced cost savings.
The results varied so widely between participants that it was impossible to measure the program's effectiveness.
Some participants discovered that the changes ended up raising their home heating and cooling expenses.
