人々はすでにサハラ砂漠での太陽光エネルギー（風力エネルギーを含む）の皮算用と試算している。

Researchers simulated the effects of around 79 terawatts of solar panels and 3 terawatts of wind turbines. Computer modeling looked at the effect of covering 20 percent of the largest desert on the planet in solar panels and installing three million wind turbines.
There would be 16X the rain in the aridest parts of the Sahara, and double that of the Sahel.
It should be noted that massive amounts of solar and wind power does directly alter the climate.
The researchers are claiming that this energy side effect would be a net positive for the world. The extra rain going to the Sahara would not be more dryness elsewhere.
Global investment in renewable energy (Solar, Wind, Hydro and biofuel) edged up 2% in 2017 to $279.8 billion, taking cumulative investment since 2010 to $2.2 trillion.
