The energy U.S. wind needs to make headway
While offshore wind scales around the world, U.S. wind can’t seem to find its sea legs. China has 129 operating offshore wind farms, followed by 39 in the UK, 30 in Germany, and 26 in Vietnam. The U.S. has just 2. Why is U.S. wind lagging behind other countries?
In the past few years, the U.S. has sought to push forward on wind. However, that’s coincided with cost surges, supply chain challenges, high interest rates, permit delays, and opposition from wildlife organizations, local residents, and fishing groups who feel there hasn’t been enough project vetting to ensure safety. Wind’s worries intensified this summer when a 300-foot-long wind turbine blade made by GE Verona collapsed on a wind farm off the coast of Massachusetts. Given the state of our planet and the extensive need for energy transition to clean, affordable electricity, our planet can’t afford to wait.
To get U.S. wind on track, we need to employ what I call the 4 considerations of problem-solving in today’s warming world: creativity, collaboration, connection, and climate.
Creativity
With surging costs, scare resources in the supply chain, and safety issues of today’s wind turbines, we need to redesign them with materials that are abundant, affordable, and durable. Sounds like a job for recycled plastics to me. Vestas, a manufacturer of wind turbines, agrees. There are many factors to consider in turbine design and what they’re working on right now might not be the right solution. However, it’s this kind of redesign thinking that’s needed given the numerous challenges.
Collaboration
Launching a large-scale offshore wind farm is an all-hands-on-deck project. Government (local, state, and federal), finance, design, engineering, marine science, wildlife advocates, and local communities have to rally around it and pool their talents and efforts. Right now, many of these parties are fighting one another and it’s sinking the projects. If we lose the momentum of this moment to the tired us-versus-them paradigm, we may lose the opportunity to make this energy transition before the worst outcomes of climate change find their way to us.
Connection
While China has many operating wind farms, ~16% of its wind power has historically gone unused, costing ~$1.2 billion. This is mostly due to a lack of connections to the grid. The energy doesn’t do anyone any good if it can’t reach them when and where they need it. Like the design of the turbines, we may also need to rethink how we connect new wind projects to the grid.
Climate
This is the bit that I find most disturbing about offshore wind because it’s the one we cannot directly control. Wind is generated by the difference between land and sea temperatures. Research is beginning to show that difference decreasing due to rapidly rising ocean temperatures from climate change, generating less wind. While we’re making this transition toward clean energy, we also need to enhance the efficiency of turbines to do as much as we can with the wind we have in an ever-hotter world.
With all these challenges for offshore wind, I wondered if it was worth it. Should we abandon the wind effort and focus solely on other forms of clean energy such as solar? As I listened to energy experts at Climate Week NYC, it became clear that the U.S. needs offshore wind as part of the energy supply mix. Wind is one of the least expensive and most efficient sources of power. Without offshore wind, the winds themselves may disappear altogether. That’s a scenario none of us can afford.
