Energy in Victoria, Australia is generated using a number of fuels or technologies, including coal, natural gas and renewable energy sources. Brown coal, historically, was the main primary energy source for the generation of electricity in the state, accounting for about 85% of electricity generation in 2008. The amount of coal-fired power has decreased significantly with the closure in 2017 of the Hazelwood power station which supplied around 20% of Victoria's electricity, and to a lesser extent with the exit of Anglesea power station in 2015. Brown coal is one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of controversy for the country. Australia is one of the highest polluters of greenhouse gas per capita in the world.

Wyoming has one of the highest wind power potentials of any state in the United States. In 2019, Wyoming had wind powered electricity generating capacity of 1,589 MW, which produced 9.85% of its electric generation, with an additional 3,753 MW under construction. However, the wind generation in that year was Wyoming's third-lowest in the 2010s. By 2020, wind capacity increased to 2738 MW and 8448 gigawatt-hours of electricity were produced from wind in 2021, more than double 2019 production. Additional wind capacity and needed transmission lines are under construction or planned, despite political headwinds from Wyoming's strong coal and oil sectors.
North Dakota is a leading U.S. state in wind power generation. The state generated 26.8% of its electricity from wind during year 2017, enough to power over one million homes.
