Since Interstate 10 crosses Arizona, experts believe the state is in need of more electric vehicle infrastructure to support the transition to more climate-friendly trucks. This comes as the Environmental Protection Agency's "Phase 3" medium-to-heavy-duty truck rule would significantly reduce greenhouse gas emissions from commercial vehicles beginning in 2027.

Anthony Harrison, head of policy and partnerships with TerraWatt Infrastructure, a company that builds electric charging stations for bigger vehicles, said federal action should be taken to encourage private sector investments to fuel the transition to electric.

"One of the major tools that we have in our toolkit to help ensure infrastructure is not the bottleneck is putting national standards in place, so we know that we need to build these things everywhere, and we need to build them at a faster pace," Harrison said.

Those for and against the EPA's proposal are focused on infrastructure, he contended, and added proponents understand the need to build more infrastructure, and faster. Opponents are worried about the challenges that may pose, as well as the financial impacts on businesses. Last year, TerraWatt announced it is developing the first network of electric heavy-duty charging centers along Interstate 10.

John Boesel, president and CEO, CALSTART, Inc., a nonprofit in the "clean transportation" sector, supports the EPA's proposal, in part because fewer emissions from the trucking industry will help lower-income communities along major freeways. The Interstate 10 corridor runs through Maricopa County, on the American Lung Association's list of worst counties in the nation for ozone pollution. Boesel recognizes the transition will present challenges, but he contends the technology to provide energy to electric commercial vehicles is already available.

"It is a problem that can be solved. We have to definitely learn some things, but it's not a barrier to the growth of the market," he continued.

CALSTART has developed a roadmap for how to implement the infrastructure needed to keep pace as more companies transition to zero-emission medium and heavy-duty trucks, Boesel said.

Minnesota is coming off another windy month of April. Those strong wind gusts may have translated into some extra cash for counties with wind turbines dotting the landscape.

Minnesota has a wind and solar energy production tax, which allows jurisdictions where these systems are located to collect revenue based on the energy that's generated.

Nobles County brought in nearly $2 million in 2023, the third highest in the state.

County Commissioner Gene Metz said over time, this extra financial stream has helped cover maintenance costs.

"We did a ten year bond basically to upgrade our buildings," said Metz. "You know, we had roofs that needed work - outside, windows, that type of thing. And we upgraded a lot of our heating and technology controlling those systems."

He said it's helpful since smaller counties have a harder time attracting larger industries to help spur economic growth.

While it's become a solid income source, Metz said turbines taken out of operation for repairs, or less windy seasons can make the numbers vary in certain years.

Minnesota supporters also are eyeing bipartisan legislation to speed up the permitting process for these energy projects, in hopes it will open up much-needed space on the power grid.

Metz, also a member of the Rural Minnesota Energy Board, said he feels addressing that issue will lead to more wind farms.

He added that having additional dollars trickle down takes pressure off local taxpayers because county budgets won't be so one-dimensional.

"We depend so much on agriculture," said Metz. "In our county, 75% of the tax levy comes from agriculture, and if that has a bad year or bad period, it's just nice to have another source of income. "

While some counties have embraced renewables, local governments elsewhere have put up more resistance as proposed projects come on board.

Metz said some of that is driven by misinformation.

He advises planning officials and constituents - worried about seeing wind farms harming aesthetics on the rural landscape - to compare them with other industries that take up more space and have deeper effects on the quality of life.

Minnesota is a leader in renewable energy - getting 54% of its electricity from zero-carbon sources last year, according to the 2024 Minnesota Energy Factsheet released today. The annual report comes from Clean Energy Economy Minnesota and the Business Council for Sustainable Energy.

Amelia Cerling-Hennes, managing director of public affairs with Clean Energy Economy Minnesota, said that's 12% better than the national average.

"We're really pleased to see about 600 megawatts of wind and solar getting added, and we're anticipating that that's going to be even higher next year as some of the large utility-scale projects that are being built right now kind of come online," she said.

Carbon emissions from the power sector also dropped 54% in 2023 with the retirement of part of the Sherco coal-fired power plant. Electric vehicle registrations went up 55%. Last year, Minnesota-based Cummins began shipping electrolyzers, which generate energy from hydrogen.

Andy Kim, president of the civil engineering firm EVS in Eden Prairie, said battery storage will be increasingly paired with large-scale solar projects in the future.

"You get uninterrupted power, you improve grid stability, and ultimately, it will lead to cost savings. And we see battery storage on at least half of our projects right now. And I would not be surprised if within the next two years, we see it on 80-90% of our projects," Kim said.

Cerling-Hennes adds the state made big strides policy-wise in 2023.

"So much happened last year, starting with passing 100% clean energy by 2040. And then following that up with a really historic energy omnibus bill. We created the Minnesota Climate Innovation Finance Authority. We funded high-voltage transmission," she said.

Tara Narayanan, lead analyst for North American regional trends with Bloomberg New Energy Finance, said energy efficiency is working - electricity consumption went down even as productivity went up. However, she notes that we need to ramp up the clean-energy transition even faster if we are to meet the goals set by the Paris Accords.

"Compare where we are going against where the U.S. has committed to go, we're really not on track. We're really going to have to make dramatic efforts in order to get to where we had committed to be in 2013," Narayanan said.

The state got $800 million in climate funding from President Joe Biden's infrastructure bill and the Inflation Reduction Act.

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.
