Climate change will damage energy infrastructure, costing trillions

Posted on January 28, 2022 by

Preface. Climate change and extreme weather will harm oil and gas exploration and production, electric power generation and increase energy demand due to sea level rise, heat, drought, floods, more storms, and blackouts.  Extreme heat and drought will force electric … Continue reading →

Pumped Hydro Storage (PHS)

Posted on October 13, 2019 by

Preface. This is the only commercial way to store energy now (CAES hardly counts with just one plant and salt domes to put more in existing in only 5 states). Though of course hydropower is only in a few states … Continue reading →

Climate change effects on hydropower in California

Posted on June 14, 2019 by

Preface. Climate change will impact California agriculture without the snow melt that allows for up to three crops to be grown a year, perhaps just one crop in the future. Not to mention the impact on the 40 million people … Continue reading →

Hydropower can’t help with the energy crisis

Posted on June 11, 2019 by

Preface. When fossil fuels are gone, there aren’t many ways to balance the unreliable, intermittent, and often absent for weeks at a time power from wind and solar.  Biofuels and burning biomass is one solution, it’s dispatchable and can kick … Continue reading →

Hydropower dams and the ways they destroy the environment

Posted on April 15, 2019 by

Preface. Hydropower comprises 71% of renewable energy worldwide.  Nations like the U.S. and Europe have dams that have reached the end of their lifespan — more are being torn down than built. In the U.S. 546 dams were removed between … Continue reading →

Underground pumped hydro storage is the only technology capable of massive storage for renewable electricity

Posted on September 27, 2017 by

[ Picard concludes that “None of the candidate technologies for massive-scale renewable and sustainable generation of ‘‘green’’ electricity deliver it in a form suitable for high-efficiency storage. None of the prospectively-massive storage modes for transformed electricity is at present well … Continue reading →

Hydropower has a very low energy density

Posted on March 17, 2015 by

To store the energy contained in 1 gallon of gasoline requires over 55,000 gallons to be pumped up 726 feet (CCST 2012). As a thought experiment look at what it would take generate all of America’s 4,058 TWh electricity, where … Continue reading →
