IEEFA has found that improving energy affordability in Australia does not have to be incompatible with emissions reduction targets. The country's aging coal fleet and network assets need to be replaced, with renewables backed by storage and transmission being the most cost-effective option. Gas-based generation has become increasingly uncompetitive, with high prices and declining consumption. Contrary to misconceptions, renewables have not been driving electricity prices up, with high gas and coal prices, coal outages, and network costs being the main factors. Faster approval processes and better market regulations are needed to ensure a smooth transition to cleaner energy sources. Reforms to improve competition, allow distributed energy resources to compete, and promote energy efficiency, electrification, and flexible demand are key to lowering household energy bills. Transitioning to modern electric alternatives, such as heaters and hot water systems, along with solar and battery systems, can significantly reduce costs. Industrial energy efficiency and electrification also offer major savings. The key pathways to improve energy affordability are aligned with net zero emissions goals, emphasizing the need for accelerated deployment of renewables, energy efficiency, and electrification. The narrative that lowering bills and cutting emissions are mutually exclusive is false.

COP30 and the Just Clean Energy Transition
The COP30 climate conference in Belém, Brazil highlighted efforts to implement the Paris Agreement by transitioning from coal to clean energy in developing countries. The Kinetic Coalition, led by C2ES, is driving investment in clean energy systems in emerging economies through energy transition credits, with a focus on affordable, reliable, and secure electricity to meet Paris Agreement goals. The Final Report of the Transition Credits Coalition (TRACTION), led by MAS, aims to establish integrity and demand for energy transition credits, emphasizing a just transition for coal plant workers and communities. The partnership with The Rockefeller Foundation and the signing of a Statement of Support for Energy Transition Credits by various sectors demonstrate a commitment to advancing energy prosperity and accelerating the clean energy transition.

New transmission towers are crucial for renewables – but contentious. Here’s where they should go
Solar and wind provide 99% of new generating capacity in Australia, with renewables supplying over 40% of power to the main grid. Australia will need six times as much solar and wind to reach net zero through electrification. Building new transmission corridors is necessary, but existing lines are not sufficient. The grid operator plans to build 10,000 km of new transmission lines, with a focus on high-voltage direct current lines to unlock renewable resources. Optimizing new transmission corridors is crucial for Australia's future grid. A study has identified potential high-voltage direct current (HVDC) transmission line corridors in Australia to connect renewable resources in northern regions to population centers in the southeast. These corridors could significantly reduce wholesale electricity costs by 8-18%. Energy storage schemes like Snowy 2.0 could also help cover seasonal gaps locally. Community buy-in is crucial for such projects, and the benefits of unlocking renewables can be quantified for each local government area. Policymakers should prioritize building these transmission corridors to meet new demand and consider pairing them with pumped-hydro schemes. The article discusses the importance of energy storage in balancing variable renewable generation and maximizing the use of transmission lines. Cheng Cheng, a Senior Research Officer at the Australian National University, highlights the role of energy storage in the transition to a more sustainable energy system. This technology helps to ensure a reliable and stable energy supply while also reducing greenhouse gas emissions. Energy storage is a key component in achieving climate solutions and increasing the efficiency of renewable energy integration.

Wind-PV-powered heat pump for low-energy residential buildings
Researchers from China have developed an optimized energy management strategy for a hybrid wind-PV heat pump system with thermal and electric energy storage. The study found that adopting seasonal interaction management strategies improved power-to-load interaction and enabled zero-energy performance. The optimal system configuration includes PV modules, wind turbines, batteries, and heat pumps. The research showed significant improvements in system performance and cost savings with the implementation of the optimized energy management strategy, resulting in a reduction in system integration factor, levelized cost of electricity, and carbon emissions, while increasing self-consumption ratio.

All you need to know about the outcome of COP30
COP30 in Belém, Brazil saw a strong focus on transitioning from promises to action in the fight against climate change, with discussions on phasing out fossil fuels, climate finance, and transitioning to renewable energy. Indigenous and frontline communities pushed for justice, leading to the demarcation of Indigenous territories and the creation of the Belém Action Mechanism for a just transition. Momentum for a fossil fuel phase-out grew, with countries like Brazil and Colombia moving towards this goal. Despite delays in funding, progress was made towards a just transition and a global push to end fossil fuels, driven by people-powered leadership. The upcoming International Conference on the Just Transition Away from Fossil Fuels aims to address the finance gap and support vulnerable nations in adapting to climate impacts.

Environmental News Network – This UW-Madison Spinoff is Making Environmentally-Friendly Cement. The Secret Ingredient is Pollution
Alithic, a spinoff from the University of Wisconsin-Madison, has developed a process that turns coal ash and excess carbon dioxide into a durable, environmentally friendly building material called supplementary cementitious material (SCM). This innovative material can replace traditional Portland cement, helping to reduce greenhouse gas emissions. By pulling carbon dioxide from the air and mixing it with industrial wastes, Alithic's process creates a carbon-negative product that has the potential to transform waste streams into profitable solutions for the construction industry.
