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 filthy. A fifth of China’s arable land … Continue reading →

Renewables must help pay for transmission and their energy storage backup of fossil power plants

Posted on November 23, 2020 by

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

Wind, solar, and natural gas are driving nuclear power out of business

Posted on February 28, 2020 by

Preface. I’m no fan of nuclear power because we may already be at peak uranium, there’s nowhere to store nuclear waste, and a spent nuclear pool fire could harm millions of people. But renewable wind and solar and natural gas … Continue reading →

Challenges to the Integration of Renewable Resources at High System Penetration

Posted on February 2, 2019 by

Preface.  This overview of challenges for wind and solar written in 2010 is still true today. We are far from being able to reach even a 50% renewable grid (excluding hydropower from the total) given the lack of storage, the … Continue reading →
