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

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

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

The Invisible oiliness of everything

Preface.  Even a simple object like a pencil requires dozens of actions to make and dozens of objects that took energy to make.  This is why it is unlikely wind, solar, or any other contraption that make electricity, have a … Continue reading

Building a national super grid in America

Preface. Renewables are not evenly distributed.  Just 10 states have 80% of hydropower (Homeland Security 2011), 10 states produce 75% of wind power (EIA 2017), and 10 states produce 79% of solar power (CE 2020). With a national grid, instead … Continue reading

Movie review of Michael Moore’s “Planet of the Humans”

Preface. This documentary was made by Jeff Gibbs, a writer and environmentalist, with Michael Moore as the executive producer. This movie is worth watching, and an entertaining and quick way to understand why rebuildable “renewables” are neither green or a … Continue reading

1688 Tons of material to build just 1 windmill

Preface.  The 2.3 MW wind turbine in this video weighs a lot more than the 900 tons I list later in this post, that’s just what I was able to hear in the video and it leaves at least half … Continue reading

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

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

Germany’s renewable energy program, Energiewende, is a big, expensive failure

Preface. After reading this post, or better yet the original 44-page document, you’ll understand why the Green New Deal isn’t working out despite being crazy expensive. The goal of Energiewende was to make Germany independent of fossil fuels.  But it … Continue reading

53 Reasons why wind power can not replace fossil fuels

Preface. Electricity simply doesn’t substitute for all the uses of fossil fuels, so windmills will never be able to reproduce themselves from the energy they generate — they are simply not sustainable.  Nor can electricity generate the high heat required … Continue reading

Challenges to the Integration of Renewable Resources at High System Penetration

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
