In fact, around 86 percent of our electricity is generated from these fuels types, with 73 percent from coal and 13 percent from natural gas.1 Around the world it’s much the same, with fossil fuels being used for electricity, heating and powering vehicles.
The world relies heavily on coal fired electricity generation because it’s often the cheapest form of generation. It’s also reliable and abundant. That’s what makes it difficult for renewable options, such as wind and solar, to compete in purely financial term
Renewable energy sources make up the remaining 14 percent of Australia’s electricity mix.2
Hydropower, which began contributing to Australia’s generation in the 1950s, is the largest source of renewable electricity, contributing 60 percent of all renewable generation and 7 percent of total electricity.
Wind, bioenergy and rooftop solar make up the other seven percent.
Wind and solar power are known as intermittent energy sources, because they rely on natural sources and can’t be relied on for consistent baseload power.
