DES MOINES, Iowa - As scientists warn that the increase in extreme weather events shows no signs of stopping, experts say it's important as ever to prepare renewable sources for the conditions.

Iowa gets more than 40% of its power from wind energy, and for the most part, wind turbines can be weatherized to operate in winter weather conditions.

Tad Miller, regional director of field operations for energy company EDF Renewables, said cold-weather packages for wind turbines can range from using thinner oil - like you would do for your car in a cold climate - to putting heaters in the gearboxes or even on the blades.

"Every manufacturer has additions or changes they can make to adapt it to their environment that will make it more more reliable there and higher performance," said Miller.

There are limits, and some of Iowa's wind turbines were shut down during the 2019 polar vortex, when the Hawkeye State saw record-breaking cold temperatures, reaching negative 30 degrees Fahrenheit.

Miller said manufacturers and operators are always trying to find new ways to make improvements.

Natalie McIntire, a technical consultant with the Clean Grid Alliance, said since the polar-vortex event, Iowa's regional transmission operator has been working to incorporate data about what the wind turbines and other power sources' capabilities are - so that weather forecasting can help them plan ahead for managing power during future extreme weather events.

"They will know in advance," said McIntire, "'oh, we're going to need to make sure that we have other resources available, because we can see that the temperatures are going to drop so low tomorrow that some of our wind plants may not be available.'"

She said if temperatures shut down wind farms in states like Iowa and Minnesota, for example, utilities within the network but unaffected by the weather could contribute resources to help.

New York lawmakers are focusing on electrifying municipal buildings.

Buildings statewide make up 32% of New York's greenhouse gas emissions and experts said electrifying them would lower heating and cooling costs, as well as reducing emissions. Inflation Reduction Act funds are available for municipalities to convert public buildings to use electricity.

Marian Brown, elected official fellow for Elected Officials to Protect America, said there is one challenge worrying elected leaders.

"One of the biggest challenges right now, and we were hearing this from folks, is uncertainty over the durability of Inflation Reduction Act funding, the IRA, with a new federal administration that's already signaling that it's not supportive of clean energy technologies," Brown explained.

President-elect Donald Trump has said he will repeal the Inflation Reduction Act but it comes with significant trade-offs. Research shows it could terminate many manufacturing jobs and cost America a chance at energy independence. Reports find conservative states are seeing the greatest benefits from Inflation Reduction Act investments.

The 2023 All-Electric Buildings Act will help get more buildings electrified by banning fossil-fuel systems in new buildings. All-electric cooking and heating will be required for new buildings under seven stories by 2026 and by 2029 for taller buildings.

Dominic Frongillo, cofounder and executive director of Elected Officials to Protect America, said the legislation comes with many benefits.

"We need to make sure we have the cleanest, most efficient, most modern technology that can protect the public health and improve indoor air quality, and make sure that we're keeping our dollars locally in our communities and our pockets," Frongillo outlined. "We need to build on that policy that New York State has passed."

The state's Building Code Council is deciding whether to include the All-Electric Buildings Act in its 2025 code update. Another bill establishing the Green Affordable Pre-Electrification Fund could help with the effort. It would allocate funds for buildings deemed unfit for weatherization and electrification, removing a major barrier to existing programs.

After years of double-digit rate hikes on electricity bills, some relief might be in sight.

Oregon Citizens' Utility Board, or CUB, has proposed a 7% to 10% yearly limit on rate increases for Pacific Gas & Electric and Pacific Power.

It is up to the Oregon Public Utility Commission to approve the proposal, and it will be making a decision this week.

Bob Jenks - CUB's executive director - said customers are struggling to absorb the 40% or 50% rate hikes from the last few years, and that something needs to be done to rein in this trend.

"We're concerned that this isn't going to stop," said Jenks. "This is in the interest of utilities to keep raising rates like this as long as they can."

Last winter's ice storm led to record power shutoffs for Oregon households, due to lack of payment of their utility bills.

If the PUC decides to adopt the cap, than PG&E's planned 10.9% increase and Pacific Power's planned 14.9% increase for January would need to be lowered.

Jenks said the system favors large companies, which pay much lower rates than households.

While industries need less infrastructure due to proximity to power supplies, he noted that new data centers are driving the need to grow the grid.

Yet, residential rates are rising more than three times faster than industrial rates.

"We think that residential customers and small-business customers are being asked to subsidize the big server farms," said Jenks, "the big data centers, like Amazon and Meta."

The Portland suburb of Hillsboro is newly home to many power-hungry data centers.

Jenks said PG&E's recent numbers show the centers use more electricity than all the residents in Washington County combined, and those numbers are expected to keep growing.

Jenks said CUB's proposal requires the PUC to mitigate rate increases that are higher than 10%.

They can do that by deferring part of the increase to the following year, or by setting the rate to the lowest level legally allowed that would still be profitable for the utility.

"Needless to say," said Jenks, "the utilities don't agree. "

The power grid will need to be dramatically upgraded and expanded in the coming years to handle the transition to renewable energy - and two new reports look at the impact on wildlife, both on and off-shore.

The placement of large onshore power grids can greatly affect migratory species such as mule deer, elk, and sage grouse.

Veronica Ung-Kono is a clean-energy policy transmission specialist and staff attorney with the National Wildlife Federation.

"Proactively planning transmission development helps to strike a balance," said Ung-Kono, "that can help wildlife have their needs met while also helping people have access to low-cost and clean energy."

Ung-Kono said more research is needed because there's still a lot we don't know about the implications for wildlife as more transmission lines crisscross the landscape.

A second report on offshore wind farms recommends buffer zones around sensitive coral habitat.

It also says cables for windmills fixed to the ocean floor must be shielded and buried to reduce impacts from electromagnetic fields.

Co-author Shayna Steingard - an offshore wind senior policy specialist with the National Wildlife Federation - said if it's done right, the clean-energy transition will preserve habitat, and slow ocean warming and sea-level rise linked to climate change.

"I think climate change presents an existential threat to all species, particularly ocean species," said Steingard. "The threats from offshore wind development pale in comparison to the threat from not addressing climate change. There is no climate solution without offshore wind."

President-elect Donald Trump has vowed to kill offshore wind development. So far, site surveys have been approved for the five wind farms planned off the California coast, but they still face years of permitting and environmental review.
