Energy represents one-third of the weight in ranking the Best States for infrastructure. This subcategory evaluates three major metrics: renewable energy usage, reliability of power grids and the average cost of electricity. Metrics were evaluated using the most recent data from the Department of Energy. Most of the energy consumed in the U.S. comes from fossil fuels, including petroleum, coal and natural gas, while about 10 percent of energy consumption comes from renewable sources. In 2016, 29 percent of all energy usage was in transportation, while 6 percent came from the residential sector and just 4 percent from the commercial category, according to the U.S. Energy Information Administration.
Oregon, which ranks No. 1 in energy, comes in third for infrastructure. Five of the top 10 states for energy also rank in the top 10 Best States overall: Iowa, Minnesota, Washington, Nebraska and North Dakota. And West Virginia, which is the worst state for energy, is also one of the poorest-performing states overall, coming in at No. 47. Montana, however, falls in the bottom half of states for infrastructure despite being top 10 states for energy.
