Olösligt skiffer

Det pågår en relativt intensiv kampanj på sina håll för att utvinna och nyttja skiffergas. EU-parlamentet har låtit göra en studie (som är mycket instruktiv och lärorik) som kommer till slutsatsen att skiffergas är en ovanligt dålig idé. Konklusionen talar bäst för sig själv:

Conclusions
At a time when sustainability is key to future operations it can be questioned whether the injection of toxic chemicals in the underground should be allowed, or whether it should be banned as such a practice would restrict or exclude any later use of the contaminated layer (e.g. for geothermal purposes) and as long-term effects are not investigated. In an active shale gas extraction area, about 0.1-0.5 litres of chemicals are injected per square metre.

This holds even more as the potential shale gas plays are too small to have a substantial impact on the European gas supply situation.

The present privileges of oil and gas exploration and extraction should be reassessed in view of the fact that the environmental risks and burdens are not compensated for by a corresponding potential benefit as the specific gas production is very low.

DĂ„ och dĂ„ kommer det kraftig kritik mot de energiscenarier som till exempel IEA publicerar i sina Ă„rliga skrifter. Som senast den hĂ€r frĂ„n en organisation som heter Institute for Energy Economics and Financial Analysis (IEEFA) och har skrivit en rapport med det klatschiga namnet “Off Track”.

The International Energy Agency has wrongly guided governments into decisions about oil, gas and coal use that are inconsistent with the long-term climate objectives of the Paris Agreement

Men Ă€r det sant? Är det IEA som vilseleder? SĂ„ hĂ€r förklarar IEA hur scenarierna konstrueras (jĂ€mför med bild nedan)

- New Policies Scenario of the World Energy Outlook broadly serves as the IEA baseline scenario. It takes account of broad policy commitments and plans that have been announced by countries, including national pledges to reduce greenhouse-gas emissions and plans to phase out fossil-energy subsidies, even if the measures to implement these commitments have yet to be identified or announced.

- Current Policies Scenario assumes no changes in policies from the mid-point of the year of publication (previously called the Reference Scenario).

- 450 Scenario sets out an energy pathway consistent with the goal of limiting the global increase in temperature to 2°C by limiting concentration of greenhouse gases in the atmosphere to around 450 parts per million of CO2.

TvÄ av de scenarier som presenteras Àr alltsÄ reflexioner av vad som hÀnder i vÀrlden och det som Àr pÄ vÀg att hÀnda till följd av de beslut som fattats i olika beslutsorgan (lÀnder, samarbetsorganisationer mm). Det Àr bilder INTE rekommendationer!

Om vi inte gillar det vi ser mÄste vi kanske rÀtta till de egna anletsdragen. Men klandra inte spegeln!
