Wind Energy

"Can wind power get up to speed?" asks

From the article:

Wind power accounted for 42% of all new electricity generation added to the U.S. grid last year

Wind still makes up less than 3% of America's total electricity generation

A new study in the Proceedings of the National Academy of Science (PNAS) found that current technology could harness enough power to supply more than 40 times the planet's present-day levels of electricity consumption.

For the U.S., there's enough wind concentrated in the Midwest prairie states to supply as much as 16 times the current American demand for electricity

The energy is there, on the breeze — it just needs to be tapped.

The problem isn't supply but distribution: in the U.S. and elsewhere, some of the richest wind resources tend to be far from the densely populated coastal areas that need the most electricity.

Another problem is intermittency
