When engineers plan where to build new wind farms and solar panels, they usually look at what the weather was like in the past. But MIT researcher Michael Howland says that's becoming a risky habit.
Climate change is shifting weather patterns in ways that could make old planning methods outdated. To help solve that problem, Howland and his team at MIT built a new planning tool that considers what the weather will look like decades from now — not just what it looked like before.
Their framework combines detailed weather forecasts with computer simulations of power systems. It shows exactly where solar panels and wind turbines should go so they'll keep working reliably as the climate changes.
The researchers tested their tool on two very different regions: New England, which has cold winters and coastal weather, and Texas, which is hot and prone to extreme heat. They found that energy systems designed only with historical weather patterns in mind could experience up to five times more power shortfalls by the year 2050. That means more blackouts and less reliable electricity for millions of people.
But here's the hopeful part: when the researchers used climate forecasts to choose project locations instead, both regions became significantly more resilient — and it barely cost anything extra.
"If we're smart when we design our power system decarbonization plans, it could cost almost nothing extra to simultaneously adapt to climate change," Howland said.
The study, published in the journal Nature Energy, is unusual because most previous research either looked at how climate change affects single technologies or studied entire continents at once. This new tool zooms in on specific regions and considers how weather impacts wind power, solar power, electricity demand, and power lines all at the same time — similar to how climate scientists study compound weather events.
The team looked ahead to 2050 because that's the typical lifespan of a wind turbine or solar farm being installed today. They found that the best spots for renewable energy projects in the future climate are meaningfully different from the best spots based on past climate data.
The research comes at a time when electricity demand in the United States is rising for the first time in over a decade, partly because of growing needs from artificial intelligence and the push to power more cars and buildings with electricity instead of fossil fuels.
The findings suggest that as communities invest in clean energy to fight climate change, they can also protect themselves from climate change's effects — without spending much more money. It turns out that thinking ahead about where to put solar panels and wind turbines isn't just good for the planet. It might also be the smartest way to keep the lights on.
