2022-08-13 Nuclear Power And Weapons Are Killing Us

The Manhattan Project in the US covered every stage of the production of nuclear weapons. This included the mining and refining of uranium, enrichment to 80 to 90% U235 for uranium bombs, fuelling nuclear reactors with uranium to produce plutonium, and reprocessing the spent fuel to extract the plutonium for plutonium bombs. It was recognised from the beginning that these processes and plants would give rise to radioactive releases that would be harmful to the plant operators and the general public, yet they were never informed. This continues to the present day, when the nuclear weapon and power industry does everything in its power to deny and understate the many and extensive harms done to all living things. To this has been added the use of uranium in bunker-breaking bombs and tank-busting shells, that spread the dust so formed over their own forces, the enemy forces, and innocent bystanders, harming them all for generations to come. The human harms include many and extensive cancers, and also non-malignant diseases such as stillbirths, deformities and mental impairment and heart disease. With so much harm already done to humans that will take up to lifetimes to express, and so much nuclear debris laying in wait to harm even more humans, it is essential to identify every strategy and measure that can reduce the total harm.

This document covers the first warnings of nuclear harms in the 1950s and - following studies beginning in the 1960s - five books of evidence by Dr Ernest Sternglass in 1981, Mr Harvey Wasserman et al in 1982, Dr John Gofman in 1990, Mr Paul Zimmerman in 2009, and Professor Chris Busby et al in 2010.

2018-10-22 ‘Electrofuels’ that increase plane ticket price by 60% only way to clean up air travel, report finds

New fuels and accompanying hikes in ticket prices will be essential to clean up air travel and avoid the worst effects of climate change, according to a new report.
Aviation is responsible for 5 per cent of global warming, and it is on track to power through a quarter of the planet’s annual carbon budget by 2050.
Despite some fledgling efforts to develop electric aircraft for short-haul flights, air travel is proving one of the most difficult sectors to decarbonise.In its analysis, European green transport group Transport and Environment (T&E) found that replacing fossil fuels in planes with “electrofuels” is the “only technically viable solution that would allow aviation to exist in a world that avoids catastrophic climate change”.
This will present a challenge to consumers as well as the industry, as the expense of these fuels means the cost of a plane ticket is projected to rise 58 per cent if they replace kerosene in all aircraft.

“The good news is that radically cleaner aviation is possible even with today’s technology,” said Andrew Murphy, aviation manager at T&E.
“Getting to zero starts with properly pricing flying and progressively increasing the use of sustainable synthetic fuels.
“There is a cost to this, but in light of how cheap subsidised air travel has become, and the incalculable cost of runaway climate change, it’s a price worth paying.”

2018-07-04 Climate and Energy Transition to Zero Carbon

Detailed Sustainable Energy Transition Path Graph - click for full size image
Planning the appropriate renewable energy installation rate should balance two partially contradictory objectives: substituting fossil fuels fast enough to stave-off the worst consequences of climate change while maintaining a sufficient net energy flow to support the world's economy.

2022-08-12 Stopping Sizewell C and all nuclear power in favour of a rational energy policy

Among the last acts of the Johnson government was the approval of a new nuclear plant - Sizewell C. The claim was that it would increase energy security and reduce carbon emissions. But the invasion of Ukraine has underlined that all nuclear sites are targets, and reduce national security. Also nuclear power would be far more costly than energy savings and renewable energy sources such as wind and solar, with storage, and could not be generating electricity before 2030. They need uranium for fuel, yet almost half comes from Russia and Kazachkstan, so that the money and carbon costs would increase twice as fast. Moreover, they require huge amounts of energy to manufacture and build, so reducing energy security until construction is complete, and this energy repaid. Yet Hinkley Point C and Sizewell C are coastal sites, at risk from flooding by sea level rise and storm surge by 2100. As decommissioning and site clearance would take at least 50 years, they would need to be shutdown before 2050.

Many reasons for stopping Sizewell C and all nuclear power are given in this collection of five documents.

2018-10-12 The New Danish Climate Plan — Together For A Greener Future

Together for a greener future
As I noted in earlier posts about the Danish government’s plan to phase out diesel and gas cars by 2030, a full plan for emission reductions over the next 12 years would be revealed this week. And indeed it was. The plan is called “Together for a greener future.” This plan is the second of two parts. The first part was the “Energy — for a green Denmark” which was boosted considerably in the rare consensus by all parties in parliament in July where for instance the plans for adding 8 gigawatts (GW) of offshore wind power was tripled to 24 GW.

While Denmark is a pretty insignificant country in the scale of things, it was actually quite an achievement to reach bipartisan agreements on upping the game as opposed to the more common dismantling. I remember that Thomas L. Friedman played with an idea in his 2008 book “Hot, Flat and Crowded” where he imagined the US being China for just one day and how that could make so many rules come into effect, fast. Well, the current president is trying to do just that, but unfortunately he has yet to push rules on avoiding catastrophic climate change. My point is that it was very refreshing to witness this consensus in July, and it should serve as an example to countries with much bigger impact.
