How are renewables impacting power bills around the world?


The International Energy Agency has found that reaching net zero by 2050 will lead to a clear decline in total household energy bills (including power, gas and fuel) in advanced economies ([url]https://www.abc.net.au/news/2025-11-13/net-zero-iea-world-energy-report-emissions-cheaper-electricity/106000244[/url]) like Australia.

While power prices are complex and depend on many factors – not just the source of power – countries around the world are showing that renewables put downward pressure on power bills. For example:

• In Ireland, research has found that wind and solar farms have saved Irish homes and businesses €840 million since 2000 ([url]https://windenergyireland.com/latest-news/7830-new-report-wind-and-solar-farms-saved-electricity-consumers-840-million-since-2000-2[/url]) (nearly AUD $1.5 billion). Ireland has a target to reach 80% renewable by 2030, which could cut consumer bills by an additional €610 million (more than AUD $1 billion).
• In Spain between 2021 and 2024, as renewable generation increased by 20%, wholesale power prices dropped by nearly 20% ([url]https://www.bbvaresearch.com/en/publicaciones/spain-more-renewables-to-continue-lowering-costs/[/url]).
• In the United Kingdom, wind power saved homes and businesses £104.3 billion ([url]https://journals.uclpress.co.uk/ucloe/plugins/isolinear/article/3584/version/1/[/url]) (more than AU$2 billion) between 2010 and 2023, due to its direct impact on electricity prices as well as reduced gas prices due to lower gas demand.

Have any countries reached 100% renewable?


Several countries including Costa Rica, Nepal, Albania, Ethiopia, Iceland and Norway ([url]https://iea.blob.core.windows.net/assets/76ad6eac-2aa6-4c55-9a55-b8dc0dba9f9e/Renewables2025.pdf[/url]) have already reached, or come very close to, 100% renewable power.

These countries have unique resources compared to other parts of the world, and are able to make significant amounts of power using traditional technologies like hydro and geothermal generation. However, other countries relying more on wind and solar are quickly catching up, like Denmark and Estonia which aim to be 100% renewable by 2030.

For example, Iceland – the “land of fire and ice” – has built a 100% renewable ([url]https://www.iea.org/countries/iceland[/url]) power system using hydro and geothermal resources. Iceland is making the most of the glaciers which cover 11% ([url]https://www.un.org/en/chronicle/article/icelands-sustainable-energy-story-model-world[/url]) of the country, and its location on the volcanic Mid-Atlantic Ridge. Iceland started its renewable journey back in the 1970s as a way of reducing its reliance on expensive imported fossil fuels, and hasn’t looked back! Thanks to its abundant renewable power, Iceland citizens pay “almost nothing ([url]https://www.bloomberg.com/news/features/2023-02-28/the-impacts-of-iceland-s-bold-clean-energy-investments)”[/url] for their electricity.
