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

Concentrated Solar Power is dying out in the U.S.

Preface.  Concentrated Solar Power (CSP) contributes only 0.06 % of U.S. electricity, mainly in California (64 %) and Arizona (24 %) because extremely dry areas with no humidity, haze, or pollutants are required. Of the 1861 MW power they can … 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

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

Why solar power can’t save us from peak oil

Preface. Embedded within the posts below are many reasons why solar electricity can’t replace fossil fuels.  All solar and wind do is add to the giant fire of burning fossil fuels with just a tiny bit more power, about 4% … 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
