Energy crisis

We have an energy crisis, and now we have a climate crisis as well. Humans generate about 12 trillion watts, or 12 terawatts, from fossil fuels and Al Gore has spoken to why we need to hit one of these targets, and in reality what that means is in the next 30 to 40 years, we have to make 10 trillion watts or more of new clean energy, somehow. Wind is the second-largest renewable resource after solar: 3600 terawatts, more than enough to supply humanity 200 times over. The majority of it is in the higher altitudes, above 300 feet, where we don't have a technology as yet to get there.

Wind energy is very abundant in many parts of the United States. Wind resources are characterized by wind-power density classes, ranging from class 1 (the lowest) to class 7 (the highest). Good wind resources (e.g., class 3 and above, which have an average annual wind speed of at least 13 miles per hour) are found in many locations. Wind speed is a critical feature of wind resources, because the energy in wind is proportional to the cube of the wind speed. In other words, a stronger wind means a lot more power.
