As leaders prepare to gather in Glasgow for the United Nations climate-change conference, you may think the world has agreed to reduce and eventually eliminate its dependency on fossil fuels, stepping up its reliance on renewable energy. Even Australia’s Prime Minister Scott Morrison, who won an election opposing costly climate policies, now proudly embraces net-zero emissions by 2050.
But the timeline for the transformation is entirely unrealistic. The politicians who make promises about how energy will be delivered within three decades can be fairly certain that they will be merely footnotes in history. British Prime Minister Boris Johnson claims that all cars sold in Britain will be electric by 2030. But he doesn’t acknowledge that on current trend there won’t be enough electricity to power all of these cars.
