Affordable electricity is a major concern around the world. In the past year, wholesale electricity prices in the United States and Europe have risen by 30–40 percent — and while consumer costs include other factors, US homes have seen a similar rise in the price they pay over the past five years. As the world navigates a new age of electricity load growth, cutting costs is paramount.
But comparing the United States with the rest of the world, electricity sources are trending in opposite directions.
On one hand, US natural gas prices are expected to double between 2024 and 2026, according to the Energy Information Administration (EIA)’s August Short-Term Energy Outlook. This trend is flatter overseas, and might change in the longer term, but it is yet another example of gas power’s volatility. Just three years ago, Russia’s invasion of Ukraine raised global prices by triple or more — leaving poorer countries in the cold as the world scrambled to replace lost supply.
Prices for renewable energy, meanwhile, continue to fall. Wright’s Law explains why some technologies get cheaper as production increases, with learning rates that remain remarkably consistent across decades. Such is the case for wind, solar, and batteries, as shown by recent reports from the UN and International Renewable Energy Agency. With global cost declines of 2.5x–4x over the past decade —and 9x for battery storage — clean energy systems are increasingly affordable around the world. Cutting consumer costs will require a full suite of solutions, from grid investment to efficiency and demand response, but governments and investors around the world are taking positive steps.
