None of Australia’s highest-emitting energy firms are fully or even closely aligned with global climate goals. Just one goes even partway, and five appeared to be taking no action at all.
When policymakers reduce electricity scarcity to a few factors like theft and vandalism, to be solved with technology and stiff penalties, they miss other factors that contribute to electricity theft.
Tesla’s stance has also shone the spotlight further onto the carbon footprint of cryptocurrency – an issue that will not go away soon.
The new commitments of state governments go some way to filling the void left by the lack of a national climate policy. The states should, and can, coordinate their efforts. Here’s how.
A proposal to change the way electricity generators and retailers strike contracts for electricity would be bad for both consumers and climate action.
The socio-economic and political factors that keep conventional energy out of reach of the poor can do the same with renewable energy.
Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.
To cope with loss of income, some Nairobi households opted for cheaper foods, or conserved their cooking fuel by preparing smaller meals.
New 5G technologies also boast the raw ingredients needed to beam wireless power to small devices.
The US electricity grid is actually five regional grids, and it’s hard to share power between them. A macrogrid could bridge the gaps, making electricity cheaper and more reliable.
The COVID-19 pandemic risks reversing progress made to increase access to affordable, reliable and sustainable domestic energy sources in Kenya.
Britain’s electricity sector continues to decarbonise, but its capacity to store energy lags far behind.
There will be more weather-driven disasters like February’s deep freeze in Texas, and energy planners aren’t prepared.
During the Texas cold snap prices jumped 30,000%. We can’t allow it to happen here.
The electricity sector is expected to play a key role in Canada’s push to net-zero emissions. Enhancing long-distance transmission can be lower the cost of providing clean and reliable electricity.
While Australia doesn’t generally experience such extreme winter temperatures, our electricity systems are still vulnerable to climate change, extreme weather and power outages.
Some Texans are receiving eye-popping electric bills after power providers passed on volatile costs to some of their customers – legally.
The weather-related impacts of climate change will increasingly threaten critical infrastructure in the future. Shifting electricity grids towards microgrids could help.
Nigeria’s attempt at privatising its power infrastructure hasn’t been without challenges but they are not insurmountable.
