• State GDP: $44 billion
• Growth in 2014: 5.1%

Wyoming continued to be one of America's top economic growth engines in 2014.

It was all about energy. Wyoming does both coal mining and crude oil production.

Even though coal prices have been on a downward trend, Wyoming actually saw a slight increase in coal production last year.

The cowboy state's crude oil production also increased in 2014. There are concerns that growth could slow substantially this year as oil prices plummeted from over $100 a barrel in the summer of 2014 to under $45 a barrel in March of 2015.

So far, Wyoming is still in good shape. The state's unemployment rate now sits at 4.1% -- far below the nation average of 5.5%.

The state also took top prize as the best state to retire in, according to a list from Bankrate. The group ranked all 50 states based on weather, cost of living, crime, quality of health care, state and local taxes, and general well-being.
