As signs of climate change surface in Minnesota, policymakers and utilities are making a hard charge to transition to clean energy sources, but questions remain about whether the power grid will be ready.

Citing independent estimates, the U.S. Department of Energy said to meet demand for sources like wind and solar, the nation will need to expand transmission systems by 60% by 2030 and possibly triple them by 2050.

Amelia Cerling Hennes, managing director of the group Clean Energy Economy Minnesota, said the nation's current grid system is old, and was not designed for the newer approach to powering up cars, homes and businesses.

"As more of us convert to electric vehicles, and getting off of our natural gas-powered appliances at home; as we're electrifying things, we're going to need more electricity," Cerling Hennes pointed out. "The current system is just not going to cut it."

There has been promising news, such as the Midcontinent Independent System Operator last year approving $10 billion in projects to integrate more renewable energy. But Hennes warned completing a new transmission line can take up to a decade, and said there should be more urgency in permitting projects, without minimizing public input.

The process is playing out with a proposed transmission line project by Xcel Energy in parts of western Minnesota.

Molly Malone, manager of Minnesota community affairs for the renewable energy developer Invenergy, said they are putting together a wind project which would connect to Xcel's planned line.

"We're not only doing it because of the strong wind resource in the area, but also because there is transmission expansion happening," Malone pointed out. "That transmission expansion is critical to the development of our wind project. They go hand-in-hand."

Not only is grid space a deciding factor, but developers also have to navigate the many layers of approval, including regulators, local governments and buy-in from community members. Hennes noted not getting them all on the same page will make it harder to meet the state's zero-carbon energy goals.

"If we're going to have 100% clean energy by 2040, which is 17 years away, the window of time is pretty short," Hennes cautioned.

This spring, Minnesota lawmakers addressed certain permitting issues, but Gov. Tim Walz acknowledged efficiencies still need to be addressed next session. Around the U.S., the Lawrence Berkeley National Laboratory said it takes five years for the average project to be completed.

New federal funding aims to revolutionize solar energy access within New Mexico's Native American communities and benefit the state overall.

The Environmental Protection Agency's $7 billion "Solar for All" program is designed to create new or expanded low-income solar programs.

Talia Martin, co-executive director of the National Tribal Program for GRID Alternatives, said the funding will help bridge the clean energy gap in Native American communities.

"In New Mexico, tangible impacts would be for household savings," Martin explained. "Which means working directly with the tribes to ensure that the savings are going to individual households as well as to the community as a whole."

According to Martin, the $62 million EPA grant awarded to the GRID Tribal Program is its largest ever. Nationwide, the agency's program is set to help at least 4,700 households in Native American communities. Across the U.S., the EPA said the program will enable more than 900,000 low-income households and disadvantaged communities to benefit from distributed solar energy.

Martin emphasized the program will allow GRID to help bolster solar storage capabilities and implement essential upgrades, while at the same time advancing their mission to support the self-determined efforts of Native American tribes to deploy clean energy on tribal lands, arguing it will be important to recruit contractors who understand the needs of tribal communities they're working with.

"It's an amazing window for Indian Country to be involved in energy development," Martin pointed out. "We want to just help foster all these relationships that it is going to take to do that."

The state of New Mexico also received a grant of $156 million from the program to overcome existing barriers to widespread adoption of distributed solar generation. In addition to the federal money for solar, Array Technologies announced last week it will build a new $50 million solar manufacturing campus near Albuquerque.

A round of public testimony wrapped up this week as part of renewed efforts by a company seeking permit approval in North Dakota for an underground pipeline carrying carbon emissions. Economic benefits were again touted but the plan still has opponents.

Last year, North Dakota's Public Service Commission denied a permit request from Summit Carbon Solutions, which wants to build a maze of pipelines in several Midwestern states. Emissions from ethanol plants would be captured for underground storage in North Dakota.

Skott Skokos, executive director of the Dakota Resource Council, said they remain unconvinced it would be a worthwhile project.

"It felt like déjà vu," Skokos observed. "I don't think Summit did anything to relax the concerns of the public."

Company officials have submitted a new application with a revised route as they try to ease concerns about safety and landowner rights. During comment periods, Summit leaders and other speakers discussed how the project would provide economic boosts, including corn prices. However, skeptics restated their concerns about potential ruptures and lasting negative effects on the landscape.

Skokos pointed out large carbon-capture projects like these have yet to prove themselves, noting smaller initiatives are not as likely to rile up opponents. He pointed to the Red Trail ethanol plant in North Dakota.

"They're storing it, basically, almost on-site, next to the facility and they're not affecting a bunch of landowners in the process," Skokos emphasized.

The Summit regulatory case has two upcoming public hearings in North Dakota, one scheduled for May 24 and the other on June 4. The company has run into similar opposition and permitting headwinds in other states, including South Dakota.

Leaders concerned about pollution and climate change are raising awareness about a ballot measure this fall on whether the state should mandate buffer zones around new oil and gas wells.

Voters will be asked to uphold or revoke Senate Bill 1173, which would require a 3,200-foot setback around any new well near schools, neighborhoods and hospitals.

Meghan Sahli-Wells, former mayor of Culver City and a leader with the group Elected Officials to Protect America, fought to phase out the Inglewood oil field and said no community should be a sacrifice zone.

"A study from Harvard found that in California, 34,000 people died in 2018, prematurely, from fossil fuel air pollution," Sahli-Wells pointed out. "These figures are three times higher than other studies."

The Stop the Energy Shutdown campaign, supported by the California Independent Petroleum Association, opposes the setback rule, arguing it could constrict local supply and cost jobs in the industry. A court put the bill on hold pending the outcome of the November election. A "yes" vote would keep the setbacks. A "no" vote would rescind them.

Clean energy advocates are also speaking out against companies operating older low-producing wells rather than pay to shut them down and seal them up properly.

Ahmad Zahra, a city council member in Fullerton, said Assembly Bill 2716 would incentivize their closure by charging companies $10,000 a day to operate so-called "stripper wells."

"We have over 40,000 oil wells currently sitting orphaned or idle, leaking methane and volatile organic compounds into the air, water and soil," Zahra emphasized.

Other states are following California's lead. Rep. Debbie Sariñana, D-Albuquerque, New Mexico, is sponsoring a bill to require setbacks near sensitive locations since more than 32,000 children in the state attend school within a mile of an oil and gas extraction site.

"Over 80 schools in northwestern New Mexico - the San Juan Basin and southeastern New Mexico, the Permian Basin - are within one mile of an oil and gas well," Sariñana noted. "Some schools are surrounded by dozens and even hundreds of wells within a single mile."
