RICHMOND, Va. – All 50 states and 139 countries can shift to 100 percent wind, water and solar power by 2050, according to a new analysis from Stanford University.

The research shows that, factoring in the health and climate-related costs of air pollution, the transition would save money and spark more employment.

Stanford engineering professor Mark Jacobson says when all costs are included, wind is now the cheapest energy source in the U.S. – even without subsidies – and solar is nearly as cheap.

Jacobson says that could mean faster economic growth.

"By transitioning, we'd create two million more jobs, both construction and permanent operation jobs, than we would lose," he maintains.

Critics of renewable energy argue it would raise the price of electricity. Jacobson says that's only true if you ignore the negative health impacts of air pollution.

According to the research, savings from reducing pollution could cover the cost of Virginia's transition in as little as four years.

Diplomats from around the world are in climate talks in Paris this week.

Electricity generated by an older coal plant can sell for as little as 3 cents per kilowatt-hour, in part because those facilities are paid for and have, until now, dodged some pollution rules.

But Jacobson says power from a newer coal plant with updated pollution controls is closer to 11 cents per kilowatt-hour, compared to 4 to 7 cents for wind or solar power.

Jacobson says there are some important costs that renewables avoid.

"Asthma, cardiovascular disease, respiratory illness,” he points out. “Climate problems getting worse, international conflicts growing because we still have fights over fuels that are overseas."

Jacobson says the analysis was done to show the transition is possible, both in terms of technology and the economy.

He adds people may not realize much of the change is already under way – in part, because using small scale methods like rooftop solar are cheaper than extending the power grid.

"Right now, there's a huge growth of electricity generation through solar, in Africa for example, where villages that previously had no access to energy now have access to photovoltaics," he stresses.

Indiana lawmakers have approved a measure to study ways to use advanced transmission technologies to squeeze more energy from the state's aging electrical grid.

The technology is a suite of hardware and software which can boost the capacity of current transmission lines and perhaps postpone the need for new infrastructure. Backers of the plan said because it is deployed on existing towers, it can reduce cost, modernize without new construction and increase the system's energy capacity.

Sen. Eric Koch, R-Bedford, a co-sponsor of the bipartisan bill, said the state faces an ever-increasing demand for energy.

"We're hearing projections of a single data center using one or maybe even two gigawatts," Koch pointed out. "A gigawatt is about the size of the consumption of residential use in the city of Indianapolis. It is a large amount of electricity being projected to be needed."

Colorado, Maine and Utah are among the states to have already deploying the system and are studying its effectiveness. Senate Bill 422, signed last week by Gov. Mike Braun, was backed by a variety of groups, including AARP Indiana, the Hoosier Environmental Council and The Pew Charitable Trusts.

Current customers and future demand for new technologies drive the need for more energy.

Carter Harms, state campaigns officer for the Pew Charitable Trusts, said the list is growing.

"Increased domestic manufacturing, increased needs from data centers, partially due to artificial intelligence, and then also increased electrification," Harms outlined. "Because of that growing demand, we're seeing strain on the electric grid."

Koch added one of Indiana's power utilities tested the system and obtained positive results.

"We did have the benefit of one of our five investor-owned utilities here in Indiana, AES, pilot a type of ATT called Dynamic Line Ratings," Koch noted. "The results were favorable, and that gave us some confidence that the 'juice is going to be worth the squeeze.'"

Oregon ranked ninth this year on The State Energy Efficiency Scorecard. The American Council for an Energy-Efficient Economy, a nonprofit research organization, ranked states based on their latest policy developments and efforts to save energy.

This year's scorecard highlighted Oregon's performance standard for large commercial buildings and efforts to upgrade existing buildings.

Jennifer Kalez, communications director for the Oregon Department of Energy, said even though the state's energy demands continue to increase with the population, Oregon's per capita energy consumption is down.

"While we may have more people in our state, we're using less energy per person thanks to efficiency and conservation efforts," Kalez explained.

Oregon also scored points for zero-emission vehicle policies, including EV rebates and emissions standards. Energy Trust of Oregon, a nonprofit helping people save energy by making their homes more efficient, was recognized in the scorecard for promoting equity.

Julianne Thacher, communications and marketing lead for the Energy Trust of Oregon, said they are designing programs to meet the needs of utility households in rural areas, those with low and moderate incomes, communities of color and small businesses.

"For the state to save more energy going forward and meet its climate goals, we need everyone to be able to directly participate in our programs and benefit and lower energy bills," Thacher contended.

The Trump administration has paused key Biden-era funding, including the Inflation Reduction Act, which supports investments in energy efficiency, clean energy and electric vehicle manufacturing. Kalez noted for now, Oregon's federal funding is still available, and federal energy efficiency programs will continue despite the uncertainty.

Appalachian communities in Kentucky are poised to become manufacturing hubs for the wind energy industry, experts say.

The region's workforce, accessible transportation routes, and stash of coal ash deposits -- which contain rare earth metals needed for turbine production -- all point to a role for Appalachia in the industry's supply chain.

Larry Holloway, professor of electrical and computer engineering at the University of Kentucky, said wind energy is a quickly growing industry in America. He pointed out more than 11% of all power produced in the U.S. comes from wind turbines and the number grows by 2% each year.

"Wind is pretty inexpensive," Holloway explained. "It depends in part on where in the country you are, how much wind you have and so forth, but it is one of the lowest cost energy sources. And in 2024, several months in a row, wind outproduced coal nationally."

According to federal data, the American wind energy industry currently supports more than 120,000 jobs and the number of wind turbine technicians is expected to grow by 60% over the next decade.

Critics have argued wind power comes with expensive production and maintenance costs, and long-term environmental impacts.

Mike Shields, senior economist for ReImagine Appalachia, said to help with the transition to wind-based power, decommissioned coal power plants could be repurposed as manufacturing facilities for parts used in wind turbines.

"We know that wind turbines are major infrastructure and there are a lot of working parts in those," Shields emphasized. "How our communities can participate in that supply chain is really the key thing that we want to take a look at."

While it remains unclear how tariffs will affect the nation's ability to develop more wind turbine parts, Holloway stressed U.S. based manufacturing is strong.

"There are a number of final assembly lines and parts that are already made in the U.S.," Holloway underscored. "We may, in fact, see even more demand in that area coming in the future as well."

According to a 2024 Pew Research Center survey, 33% of Americans think a wind turbine farm would positively affect their local economy, while 9% said wind turbines would hurt it. Another 27% said installing a wind turbine farm would make no difference.
