The 300 Year Party

Published: August 2021


Imagine taking a magic carpet ride through northern Europe from east to west in Biblical. The area is circled on the map shown below — an area that Ugo Bardi rather unkindly refers to as a "vast regions of fog and swamps, inhabited by hairy Barbarians . . . the area we call today "Western Europe".

The Shape of Net Zero (1): No Substitute

Submitted by gwddev on Mon, 01/23/2023 - 5:23 pm
The central theme of Net Zero programs is that our use of fossil fuels must cease within the next two or three decades. This leads to the question as to whether there any other alternative energy sources that can replace the fossil fuels while allowing us to maintain our current, energy-profligate way of living. In this article we identify the features of fossil fuels, particularly oil, that make them so attractive, and that makes it unlikely that we will find an equivalent replacement.

Alice, the Red Queen and ERoEI

Faster! Faster!

In Lewis Carroll’s famous story Through the Looking-Glass the protagonist, Alice, meets the Red Queen. Suddenly they start running.

Alice never could quite make out, in thinking it over afterwards, how it was that they began: all she remembers is, that they were running hand in hand, and the Queen went so fast that it was all she could do to keep up with her: and still the Queen kept crying ‘Faster! Faster!’ 

Alice and the Queen run faster and faster until,

The Shape of Net Zero (2): Alternative Energy

Submitted by gwddev on Mon, 01/23/2023 - 5:23 pm

The good old days

This post is the second in the series ‘The Shape of Net Zero’. The series is based on an understanding that we cannot simply switch out one source of energy (fossil fuels) with another (wind, solar, nuclear and others) and carry on with Business as Usual. We need to consider the following parameters to do with a switch in the basics of our energy supply.
