Austin, Texas, recently converted to using 100 percent renewable energy that is produced at wind farms in west Texas.
Going green will cost the city of Austin $8.5 million in the next year, but costs will diminish to about $3 million a year by 2021, according to the Austin American Statesman. The plan is set to save the city money, as well as cut Austin's contribution to global climate change by reducing greenhouse gas emissions over the next 50 years.
"I agree with the scientific community; global warming is a reality, and we will continue to lead American cities by maintaining our community vision for carbon reduction," Mayor Lee Leffingwell said in a statement quoted by the Statesman. "I am hopeful that other cities will be inspired to follow suit, now that our vision has become a reality."
The city is now using approximately 400 million kilowatt-hours of renewable energy, which officials believe makes Austin the largest U.S. city using 100 percent green energy, Government Technology reported.
By transitioning to green energy, the city will be complying with one of the goals of the Austin Climate Protection Program, which was adopted by the city council four years ago to reduce pollution.
The governor of Texas and Republican presidential hopeful Rick Perry recently challenged President Barack Obama's green energy programs in an effort to gain ground in the presidential primary race, Businessweek reported.
