Paths to 100% renewable power, globally

[GregLocock]

It's cheap and easy apparently https://yle.fi/a/3-10736252 . No mention of the costs of storage or transmission lines.

You can do it in Kazaqkstan Transition towards a 100% RE-based energy system was modelled for five scenarios considering different energy system structures, from a limited power sector consideration to a full energy system for power, heat, transport, industry with desalination sectors. The modelling results show that a 100% RE based system is achievable for the applied case ofKazakhstan even considering all energy sectors’ demand and additional emand for international transport, chemical industry feedstock and desalination, which are typically not included in sustainable energy transition studies utilising high shares of renewables. The feasibility of a100% RE system for the case of Kazakhstan, a country with one of the harshest climate conditions and a highly energy-intensive economy, canexhibit the possibility of such a transition in other regions with similar climates, economic and geographic conditions.

Luckily somebody has a robust plan

• Presents robustly modeled scenarios to achieve 100% renewable energy by 2050
• Provides policy-makers with detailed pathways to achieve the Paris Climate Agreement goals
• Includes recommendations for policy-makers to set out a clear implementation agenda

Achieving the Paris Climate Agreement Goals

This open access book presents global and regional Representative Concentration Pathways (RCPs) for 100% renewable energy and non-energy greenhouse gas in order to keep climate change significantly under +2°C and thereby achieve the Paris Climate Agreement goals.

This is the one I'll try and take seriously.

That's ironic, Kazakhstan's primary export is fossil fuels which will be the source of funding.

See how China is advancing in renewables... and cutting back on coal.

China isn’t cutting back on coal , they’ve expanded construction plans again.

China to Keep Building Coal Plants Through 2027 Despite Climate Concerns

Their coal consumption continues to grow, and their forecast for “peak coal” keeps getting pushed out further.

The narrative that China is cutting back on coal doesn’t match the facts. Their coal use is still increasing.

 

[GregLocock]

I wonder why dik keeps pushing this lie. It is easily refuted. Here's what the AI thingo says

China is the world's largest coal consumer, using more than half of the global total. While coal consumption has been relatively stable in recent years due to slower economic growth and government policies, it has shown recent growth and then a slight decline. In 2023, China's coal consumption increased, reaching a total of 4.883 billion metric tons.
and here's Statistica's take.

 

[Tomfh]

It’s the same line repeated everywhere: China is investing heavily in renewables and cutting back on coal. Never mind that their coal consumption keeps rising and shows no sign of slowing. Just hold the line and keep chanting the slogan: “China is cutting back on coal.”
