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

Solar PV requires too much land to replace fossils
Preface. This is a brief summary of the Capellan-Perez paper that calculates the land needed to use solar to replace electricity as well as the land needed if solar were to replace all of societies use of energy (i.e. transportation, … Continue reading
India wants to build dangerous fast breeder reactors
Preface. India was planning to build six fast breeder reactors in 2016, but now in 2018, they’ve reduced the number to 2. This is despite the high cost, instability, danger, and accidents of the 16 previous world-wide attempts that have … Continue reading
Germany’s wind energy mess: As subsidies expire, thousands Of turbines to close
Preface. This means that the talk about renewables being so much cheaper than anything else isn’t necessarily true. If wind were profitable, more turbines would be built to replace the old ones without subsidies needed. Unless they can be dumped … Continue reading

Renewable EROI must include storage, low capacity factor, wide boundaries
[ Trainer argues that when you consider how the capacity factor of wind and solar are to fossil plants, seasonality of wind and solar the number of facilities is quite large to deal with the intermittency problem. Therefore the storage … Continue reading
