An official report lays out different scenarios for the cost of transitioning away from fossil fuels to net zero by 2050

Britain’s official energy system operator has attempted to work out what achieving net zero carbon emissions will cost, with its figures showing surging spending in the coming years.

The scale and speed of the shift to a low-carbon economy, and how to fund it, are hotly debated by political parties.

The decline of the coal export industry could come even faster than expected, and we need to do more to manage the economic risks

Green light intended to limit amount consumers pay for windfarms to turn off during periods of high generation

Three major UK electricity “superhighways” could move ahead sooner than expected to help limit the amount that households pay for windfarms to turn off during periods of high power generation.

Current grid bottlenecks mean there is not enough capacity to transport the abundance of electricity generated in periods of strong winds to areas where energy demand is highest.

The capacity of Australia’s main electricity grid will need to triple by 2050 – including a fivefold expansion of large-scale wind, solar and storage – under the most likely development path, the national energy market operator says.
