To find out, the researchers ran a simulation of a 2030 wind - power plant using all the SMART innovations, operating at a site with
roughly average wind resources.

A NOAA website on atmospheric rivers contains this fascinating statistic that illustrates just how much moisture can be transported by
winds in the mid-to-upper atmosphere: «A strong atmospheric river transports an amount of water vapor
roughly equivalent to 7.5 - 15 times the
average flow of liquid water at the mouth of the Mississippi River.»
To put this in perspective, a 100MW (
roughly average size for Australia)
wind farm can be expected to generate, on
average, around 6,000 MWh in a week and the
average weekly power consumption for the whole of SA is about 300,000 MWh.
On
average throughout the year, and depending on location, modern
wind farms produce 10 - 45 % of their rated maximum power capacity,
roughly double the annual capacity factor of the
average solar PV installation (5 - 30 %).
The programme has a budget of around $ 15 billion, shared between 35 countries — or very
roughly $ 12 million per year, per country on
average — barely enough cash to finance a small
wind farm.
Average wind farm installation prices have dropped to
roughly $ 1,590 / kW (kilowatt).
By one calculation,
roughly 310 square miles are required on
average for a
wind facility to generate 1,000 megawatts of electricity and 60 square miles for a solar facility.
Based on data available from the National Renewable Energy Lab, the area may support
average wind speeds of
roughly 8.5 meter per second (19 MPH), with annual capacity factors over 42 %.
An
average wind farm takes up
roughly 4,000 acres and requires 25
wind turbines as tall as 30 story buildings — a huge expanse of land.
