If global energy consumption were to be cut by 60 per cent by 2050, 10 billion people could still benefit from decent living conditions, a new study has found. Scientists at the University of Leeds estimated how much energy would be required to provide basic human needs like food, water, mobility, shelter and hygiene, to the world’s population. They also factored in more modern necessities like high-quality healthcare, education and access to technology including phones, computers and the internet. The study found that decent standards of living could be provided to a growing global population for less than 40 per cent of the energy used around the world today. This means that clean energy could easily suffice for the expected 10 billion people living on our planet by 2050. “Currently, only 17% of global final energy consumption is from non-fossil fuel sources. But that is nearly 50% of what we estimate is needed to provide a decent standard of living for all in 2050,” says Dr Joel Millward-Hopkins, lead author of the study. “Overall, our study is consistent with the long-standing arguments that the technological solutions already exist to support reducing energy consumption to a sustainable level.” Clean energy […]
