Anthony James writes in The Conversation (2.5.16) about the economic and policy challenges that need to be overcome in order to transition our energy production to a more renewables-based footing.
‘To have any chance of preventing dangerous climate change, the world needs to reduce greenhouse gas emissions to net zero or even negative by mid-century. Many experts suggest this means we need to completely phase out fossil fuels and replace them with renewable energy sources such as solar and wind.
‘Several studies have concluded that 100% renewable energy supply systems are technically and economically feasible. This informs the widespread view that fossil fuels can be more or less “swapped out” for renewables, without significant economic consequences.
‘We are strongly sympathetic to the need for a rapid global shift away from fossil fuels. But new modelling conducted independently and made publicly available by my colleague at the Understandascope, Josh Floyd, suggests that such a transition may face significant challenges.’
