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

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

41 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.  Consider the life cycle of a wind turbine … 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

Why it is futile to think that Wind could ever make a significant contribution to energy supplies

Matt Ridley. May 15, 2017. Wind turbines are neither clean nor green and they provide zero global energy. Even after 30 years of huge subsidies, it provides about zero energy. The Spectator. The Global Wind Energy Council recently released its … Continue reading

Wind and solar need natural gas to balance intermittent, variable, and seasonal power

[ The highest wind states are getting to be enormously dependent on natural gas to balance wind and solar as this EIA article about California below shows.  Yet conventional natural gas has peaked — half our natural gas– and is … Continue reading
