Forests make the wind that carries the rain across continents

Posted on April 29, 2021 by

Preface. This is a controversial theory that if true, “could help explain why, despite their distance from the oceans, the remote interiors of forested continents receive as much rain as the coasts—and why the interiors of unforested continents tend to … Continue reading →

Minerals essential for wind, solar, and high-tech, are anything but clean and green

Posted on January 16, 2021 by

This is a book review of Pitron’s “The rare metals war”.  To produce the metals and minerals to make a transition to wind, solar, nuclear and so on would be incredibly destructive and polluting. A fifth of China’s arable land … Continue reading →

Renewable costs don’t include transmission & energy storage backup from Nat Gas & Coal plants

Posted on November 23, 2020 by

Preface. Wind and solar advocates don’t include transmission and backup costs in their net energy and cost calculations. But without fossil backup, the electric grid will come down due to lack of storage. There is almost nowhere left to put … Continue reading →
