One of the largest obstacles to plentiful and abundant wind power is not creating them, but the transportation of the components themselves — turbines and blades. We've all seen the photos of massive trucks carrying these parts on the interstate, but we must keep in mind that trucking is not the only means of transportation in the world. 

A company called Radia is building the "WindRunner" that hopes to complete the same task by air, by 2030. The need for such an oversized plane couldn't be clearer:

Any larger and the blades couldn’t be moved over land, since they wouldn’t fit through tunnels or overpasses, or be able to accommodate some of the sharper curves of roads and rails.  - IEEE Spectrum

The need for larger windmills on farmland is a task that is global. You'll need less infrastructure because, as IEEE states for the following reasons:

The turbines would be nearly twice as tall, so they’ll reach a higher, gustier part of the atmosphere. And big turbines don’t need to spin as quickly, so they would make economic sense in places with average wind speeds around 5 meters per second compared with the roughly 7 m/s needed to sustain smaller units. 

Those who care about the carbon footprint of such an enormous planes (including me) have concluded that such a transport haul would only be slightly higher than that of trucking them across countries due to the fact that wind power itself is becoming more efficient with new technologies and needing fewer of them over the lifetime of these projects. 

Battery technology in aviation is growing at a rapid acceleration when considering startups such as that of the eVTOL (electric vertical take-off and landing) industries, but more work is needed for larger capacity aircraft, such as battery weight, distribution, and efficiencies within the entire electrical system of the craft.

The integration of these emerging technologies is expected to significantly impact the future of electric aviation. As battery technologies continue to advance, with ongoing research into higher energy densities and faster charging capabilities, the feasibility of fully electric commercial aircraft will improve.

Even as the United States has retreated from the world in the realm of renewables, the rest of the world has not. The Boulder, CO based company will likely have global customers. Such research and development must continue in this fast-growing area. Looking at new ways to solve classic problems is a sign of innovation, not stagnation.
