On Dec. 30, during a special session of the Tennessee Valley Authority board, a decision was finalized to invest significant resources into retrofitting two units at its older, Shawnee coal plant in Paducah, KY. As explained in an earlier SACE blog, TVA had to make a decision concerning Shawnee Units 1 and 4 by December [...]
We are exactly 9 days away from the Environmental Protection Agency’s (EPA) official release of final rules for coal ash regulation that have been in the works ever since the catastrophic Kingston disaster of 2008. Since then, it has taken almost 6 years and countless efforts by citizens and advocates to sound the alarm on [...]
This blog was co-authored by Sandra Upchurch, SACE’s Memphis Energy Organizer. As fall descended on Memphis, over 250 people attended the Sierra Club’s 13th Annual Grassroots Community Conference. This was the first year the conference was hosted by the University of Memphis, which joined Sierra Club and other community groups in discussing this year’s conference [...]

In 1957, the price of gas was just 24 cents a gallon, [...]
New wind turbine technology is a game changer for wind energy opportunities in the Southeast. In just five years, wind turbines have greatly evolved to be more suitable across the region. Taller turbines and longer blades are capable of capturing more wind, which results in harnessing more electricity and reducing costs. But are these wind turbines too big?
Last month at the United Nations Climate Summit in New York, President Obama acknowledged America’s responsibility to act on climate change. On the eve of the U.N. Summit, hundreds of thousands of people marched on the streets of New York’s financial district and called for aggressive action from the private sector to curb global carbon emissions, which increased by [...]
So there’s this new group, CoalBlue, which claims that “A clean-energy, low-carbon world can only be achieved with clean, low-carbon coal.” I got to thinking, what is low-carbon coal? According to the World Coal Association, “Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen.” So, coal without (much) [...]
Solar photovoltaics, wind energy and solar thermal technology costs have all declined pretty substantially since Lazard’s analysis last year. Natural gas and energy efficiency costs have stayed the same, although to be fair, energy efficiency’s starting low cost of $0 per megawatt of energy saved is hard to beat. Meanwhile, coal, nuclear and integrated gasification combined cycle power costs continue to increase.
The ALS ice bucket challenge is a drop in the bucket when it comes to wasting water. Coal-fired power plants waste way more water than the ALS ice bucket challenge.
Today the Tennessee Valley Authority (TVA) Board of Directors voted unanimously to retire all three coal-fired units of the Allen Fossil Plant (990 MW) in Memphis and approved replacement with a new 1,000 MW natural gas combined cycle (NGCC) plant. TVA plans to build the new 1,000 MW NGCC plant directly across from the current [...]
