Extreme weather is behind much of the crisis, but it will make the transition to new energy sources more complicated.
India and China are the cheapest places to install rooftop solar, while the US, Japan and the UK are the most expensive.
Four years after Hurricane Maria wreaked havoc on Puerto Rico, federal money to rebuild its electricity system is finally about to flow. But it may not deliver what islanders want.
A shift to heating our homes by heat pumps would put massive pressure on the electricity grid.
While the outcome of the 2021 federal election offered little in the way of change, it may have left Canada better positioned to make progress on reducing greenhouse gas emissions.
Takeover bids for Australia’s last listed energy network companies suggest these monopolies are charging way more than necessary.
Building even more power poles and transmission lines won’t avert outages when major disasters strike.
Electric cars are still more resilient to price shocks than vehicles running on fossil fuels.
