Power density of biomass, wind, & solar take too much land to replace fossil fuels

Preface. Vaclav Smil writes “The fact that wind, solar, and biomass have incredibly low energy density per square meter means that a fully renewable system to replace the 320 GW of fossil fueled electricity generation and 1.8 TW of coal, … Continue reading

U.S. House 2013 “Exports and the Changing global energy landscape”

[ My excerpts from the house hearing below is another “let’s export Natural Gas to our allies now that we’re energy independent”.  The driving force is not making even better friends with Europe and keeping bully Russia away (though that’s … Continue reading

Permafrost will limit natural gas, oil, and coal extraction

Preface. For many people, it’s comforting to know that about 25% of remaining oil and gas reserves (we have the know-how and economics to get it) and resources (beyond our technical and monetary capability) are in the arctic. They assume … Continue reading

Why is nearly all solar power built where subsidies are the highest?

If solar net energy return is as high as some solar advocates claim, why does solar need any subsidies? And not just U.S. subsidies, it’s subsidies on top of subsidies when you add in that we’re buying Chinese government subsidized … Continue reading

Richard Heinberg: Will the US really be a major energy exporter?

[ I read this the day it was published (January 16, 2017) at resilience.org here, but thought it would be interesting to post in the future to see if the EIA predictions were as optimistic as Heinberg and Hughes thought … 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

California hits the solar wall

[ What is a solar wall?  Read part 1: California could hit the solar wall and then excerpts from the following article in the financial times, Britain’s Wall street journal.  I’ve also reworded some of it. Renewables are rendering existing … Continue reading

Why railroads are against running locomotives on natural gas

Since oil is finite, natural gas was seen as a fuel that could extend how long oil lasted by being a “bridge” fuel.  Since natural gas is finite also, and would lead to dependence on unstable foreign nations, the plan … Continue reading

EROI of Canadian Natural Gas. A peak was reached despite enormous investment

[ Although I’ve extracted much of this paper, it is not complete—there are missing equations, figures, tables, and text– so see the paper for details (it is available online).  I’ve rearranged the order of the paper.  The conclusion is just … Continue reading
