Renewables: not enough minerals, energy or time and mining is destructive

Preface. Electricity generating contraptions like wind and solar can’t replace the 50% of oil used in global manufacturing, because they can’t generate the high heat needed, or run battery or catenary electric trucks as I explained in “When Trucks Top … Continue reading

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

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

Batteries use rare, declining, critical, & imported elements from unstable countries

Preface.  Since oil and other fossils are finite and emit carbon, the plan is to electrify society with batteries.  But doh!  Minerals used in batteries are finite too.  And dependent on fossil-fuels entirely in their life cycle, from mining trucks … Continue reading

800 scientists: Burning forests for electricity & heat releases more 1.5x more CO2 than coal, 3x more than natural gas

Preface. The 2015 Paris climate change agreement states that burning biomass is carbon neutral. Not true. Over 800 scientists have written the European Parliament to tell them that burning wood for heat or electricity emits 1.5 x more CO2 than … Continue reading

Offshore wind turbines: Expensive, risky, and last just 15 years

Preface: The Department of Energy high wind penetration plans require a lot of offshore wind. But is it possible, affordable, or wise to do this? Corrosion leads to a short lifespan of just 15 years. To reduce maintenance, offshore windmills … Continue reading

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

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

The Invisible oiliness of everything

Preface.  Even a simple object like a pencil takes hundreds of actions and objects requiring fossil energy to do and make. Not electricity.  This is on of many reasons why wind, solar, or other contraption that make electricity can’t replace … Continue reading

Far Out #4: Power out of thin air, power out of freezing air, & Fruit power

Preface. To get power out of thin air after oil, the 90% of people who have had to go back to farming are going to be making protein nanowires from microbes in the chicken coop in their spare time. Scaling … Continue reading

EV cars and utility scale energy storage batteries are not likely to materialize

Preface.  Clearly there’s not enough minerals and metals to shift from fossil fuels to electric vehicles and utility scale battery storage, due to peak critical elements, peak platinum group elements, peak precious elements, peak rare earth elements, and peak everything … Continue reading

How much oil left in America? Not much

Preface. If you think we have no worries because we can get arctic oil, think again. We can’t because icebergs mow drilling platforms down in the ocean. On land, massive amounts of expensive new drilling rigs, roads, rail lines, platforms, … Continue reading
