A report by the Sierra Club rates utility companies for what they say they are doing to transition to cleaner energy sources, compared to what they are actually doing.

In the analysis, the Tennessee Valley Authority is slowly reducing its reliance on fossil fuels and received a "D" grade for its transition to renewable energy.

Amy Kelly, field organizing strategist for the Tennessee chapter of the Sierra Club, said the TVA has proposed adding six natural gas turbines to the Allen Combustion plant in Memphis. She warned of rate hikes for customers.

"Even though they say their rates are low, by adding more gas, they're adding this volatile fuel cost to people's bills," Kelly pointed out. "I think people should demand that other options be looked at. We already know that solar is cheaper than gas."

Kelly pointed out the TVA has made promises to decarbonize 70% by 2030, and 80% by 2035. She argued the utility is not making sufficient moves to meet the goal.

The TVA is accepting public written comments on the proposal for the turbines by Nov. 13.

Kelly added the Sierra Club has spoken with local residents who would rather see the TVA invest in renewable energy for the area. She reported they are concerned about pollution, since the current combustion turbines have not been running at the Memphis site.

"They are worried about their water supply, which is an aquifer that supplies the city's water," Kelly pointed out. "And that there was no, really, consultation with the community before these plans were put out, as well as there's no alternative that TVA is looking at."

Kelly emphasized adding six turbines to the Memphis site would have very little impact on local employment.

The Inflation Reduction Act passed last year made funding available to companies to fight climate change.

Noah Ver Beek, energy campaigns analyst for the Sierra Club's Beyond Coal Campaign and the report's co-author, said many utilities are still delaying the transition to cleaner energy. In part, he said it's because many utility incentives are tied to the performance of fossil fuel-based assets.

"The Inflation Reduction Act, the IRA, it includes this great big pot of money that utilities can take advantage of to build out more wind and solar and storage," Ver Beek stressed. "At the same time, we see across modeling that's going to lower utility bills for Americans, that's going to increase reliability. But we haven't seen utilities really take advantage."

Ver Beek added people of color and low-income communities continue to be exposed to higher levels of dangerous air pollution than other groups, and are at higher risk of developing chronic diseases related to pollution.

Two new studies find that without sustained intervention, California may permanently lose big sections of old-growth giant sequoia groves.

The majestic trees only grow on the western slope of the Sierra Nevada. Since 2015, 20% of them have died, mostly in three megafires in 2020 and 2021.

David Soderberg, Ph.D, a biologist with the U.S. Geological Survey and a study co-author, said the blazes incinerated many of the older, seed-bearing trees.

"You're getting much larger patches of fires burning at what's called high severity. So, you have this kind of bad combination for the sequoias where many more of the mature trees are dying, and there are many fewer of the seedlings regenerating," he explained.

The studies show there are substantially fewer seedlings than in the past, and those that germinate are imperiled by drought and heat stress linked to climate change. The Giant Sequoia Lands Coalition partners have planted more than 500,000 native seedlings in severely burned areas where reproduction has been insufficient.

Paul Ringgold, chief program officer with the Save the Redwoods League, said the idea is to give forest regeneration a head start.

"When you're planting seedlings, you're planting trees that have been grown in the nursery for two years or more. They're more robust than a seedling that is sprouting from a seed, giving it a little bit of an edge against the impact of drier, hotter summers," he said.

Old-growth sequoia are the world's largest trees and depend on fire to reproduce. But Ringgold noted that past fire-suppression efforts have led to a buildup of excessive fuel loads in the forests. So, extensive projects are underway to clear out dead vegetation and make the groves more resilient to fire.

Nearly 10,000 Montanans have petitioned the U.S. Forest Service to prevent mining activity in the iconic Smith River watershed.

The Smith is known for its majestic views and numerous wildlife species but it is also a huge draw for outdoor enthusiasts seeking to "disconnect." The Smith River Public Lands Coalition has called on the Forest Service to withdraw mineral leases granted to a company planning a $4 billion copper mine on private land near Sheep Creek, which feeds the Smith more than half of its water.

Josh Seckinger, a Bozeman-based Smith River guide, estimated he has floated the 5-day, 59-mile-long Smith 100 times. He thinks the copper sulfide mine drainage would be devastating.

"It just decimates anything with gills downstream," Seckinger pointed out. "That's fish, that's amphibians, that's aquatic bug life. It's a terrible way to sterilize a river."

Mine developer Black Butte Copper said it is committed to preserving Montana's water while creating economic development opportunities in the state, and claims it can build the mine in an environmentally friendly way.

Seckinger noted beyond the environmental and wildlife damage the mine drainage could cause, it also threatens the local landscape and the recreational economy built around the Smith River. He argued it is not just a hit to the businesses but to Montanans who want to experience the trip. It requires winning a permit in a state lottery.

"It is my hope that every resident of this state puts in for a lottery permit and wins, so they get the chance to experience this place," Seckinger emphasized. "Because once you experience this place, you understand immediately why it needs to be protected."

Black Butte Copper has bought nearly 700 claims on the public lands surrounding the one near Sheep Creek, potentially allowing the company to further expand its mining operations.

A Michigan environmental group is addressing an appeal challenging the state's decision to approve the enclosure of the Enbridge Line 5 pipeline.

Built in 1953, this pipeline transports up to 540,000 barrels of petroleum daily through the Great Lakes.

Enbridge aims to build a protective tunnel around a four mile segment at the Straits of Mackinac, which connects Lake Michigan and Lake Huron.

Environmental groups and tribal leaders want the state to reverse Enbridge's permit, citing concerns about a potential catastrophic oil spill.

The nonprofit group Oil & Water Don't Mix is dedicated to preventing oil spills and promoting clean energy - and they support the appeal.

David Holtz, an international coordinator with the group, discussed the next steps.

"And the next big hurdle that the tunnel will have will be during the federal permitting process," said Holtz, "so we're going to be focusing on that in the coming days."

Enbridge spokesperson Ryan Duffy said in an email statement that Line 5's safety is exclusively regulated by the Pipeline and Hazardous Materials Safety Administration.

Enbridge maintains that it also conducts internal inspections via an MRI-like tool known as a "pig" that travels the line, recording data on the pipe's thickness and looking for cracks, dents or signs of corrosion.

Holtz said his organization will continue its efforts to make the public and the federal government aware of what needs to be done regarding Line 5.

"The need for the Biden administration," said Holtz, "to take a stand in support of its own climate policy by rejecting the tunnel."

Holtz added that the permitting process, known as the Environmental Impact Study, will be open for public comment - and is set for early next year.
