The U.S. Energy Department said 13 states will get $5 million in funding to advance their local efforts to develop a clean-energy economy.

A state energy program from the federal department of energy has awarded more than $50 million in funding to 33 states and territories to help advance energy efficiency and renewable energy programs.

"States and territories have used these funds to advance clean energy in a number of ways, including accelerating the use of energy service performance contracts and establishing self-sustaining financing models that reduce barriers which limit investment in residential, commercial and industrial energy efficiency," the federal department said Wednesday.

An August report on state emissions from the Energy Information Administration finds a decline in 37 states and an increase in 13 from 2000 to 2011. Nevada during that period had the greatest decrease in emissions with 26 percent, while Nebraska had the largest, also with 26 percent.

Emissions vary by fuel type. Coal in 2011 accounted for 81 percent of the emissions from West Virginia, while Vermont and Hawaii each had petroleum account for 92 percent of their emissions.
