Enough minerals for a solar, wind, & battery transition from fossil fuels?

Posted on March 12, 2022 by

Preface.  The transition could require as much as $173 trillion in energy supply and infrastructure investment over the next three decades. One HELL of a lot of metals needed – questionable if possible in in three decades, especially with China … Continue reading →

Not enough rare metals to scale up solar power

Posted on February 21, 2021 by

  Preface. Sunshine may be free, but the materials to make solar contraptions sure aren’t.  Since sunshine arrives in a diluted form, vast expanses of solar photovoltaic panels will be needed to produce the world’s 24,000 Terawatt hours of electrical … Continue reading →

Why rare and valuable metals are not recycled

Posted on February 18, 2021 by

Preface. This is a post about why rare and critical metals aren’t recycled at all or at best, just a small percent. Basically it is still cheaper to mine them from scratch than to try to separate them out from … 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 →

Ivanpah Biggest solar power plant ever – $2.2 billion for only 100 MW

Posted on October 19, 2014 by

The $2.2 billion dollar Ivanpah Solar power plant generates 100 MW of power when you take the 25% capacity into account (not 400 MW).  That’s enough power for 25,000 to 50,000 homes (not 140,000 as claimed).  There are 116,700,000 households … Continue reading →
