Insight and inspiration in turbulent times.
If we trim energy use in the manner I’ve described above, we can reduce per capita energy use in the Peasant’s Republic of Wessex by a little more than half its present value – down to around 1.3 kW per capita.
The impacts of non-CO2 aircraft emissions at high altitudes came to prominence back in 1999 following publication of a special report by the International Panel on Climate Change (IPCC) on aviation. This estimated the total historic impact of aviation on the climate to have been two to four times higher than for CO2 emissions alone.
A lively debate is ongoing on what should be the minimum energy return for energy invested (EROEI) in order to sustain a civilization. Clearly, one always wants the best returns for one’s investments.
In 2011, while working toward a Ph.D. in American Studies at the University of Minnesota, Matthew Schneider-Mayerson began a study into the peak oil community. His book Peak Oil: Apocalyptic Environmentalism and Libertarian Political Culture is the result of this research.
Why are the Saudis content to allow oil prices to remain this low and possibly drift lower? I believe it’s because their war on shale never ended; they mean to destroy the long-term financial viability of oil from shale deposits–and that job won’t be finished until investors say, “Never again!”
“Microgrids, not large-scale power generation, will be the most effective way to provide electricity to those still unconnected,” Wilder says. Microgrids are essentially small power grids customized for single communities.
Carbon Brief analysis shows the UK’s CO2 emissions fell by 5.8% in 2016, after a record 52% drop in coal use. The reduction would leave UK CO2 emissions some 36% below 1990 levels. The huge fall in CO2 from coal use in 2016 was partially offset by increased emissions from oil (up 1.6%) and gas (up 12.5%).
A report on the world’s oil depletion problem published several years ago by an obscure association of anonymous consulting engineers and professional project managers is suddenly coming under fierce criticism.
The oceans of the world are a vast unexploited source of clean, reliable and predictable renewable energy. Could this energy help replace fossil fuels and be a solution to climate change?
A bi-lateral partnership with the UK could certainly result in economic benefits for both. More than that, collaboration could offer important secondary (political) benefits.
It’s understandable that environmental organizations and activists would want to build public enthusiasm for renewable energy. But making wind and solar seem like they’re doing better than they really are could come back to bite proponents — and the climate.
Entropy is an important concept, but it must be correctly understood to be useful. It is no good to use it as an excuse to pander unbridled catastrophism.
