For David and Ruth Hudspeth, the process of turning their 1950s brick veneer house in Melbourne’s eastern suburbs into a cosy, efficient and fully electric home took several years.

They started with insulation in the ceiling and replacing an old and “pretty dangerous” gas heater. They swapped their leaky hot water system for a heat pump, and built a roof over the outdoor deck for shade and extra solar panels, later adding an electric car and a home battery into the mix.

Experts say increased use of crops for fuel is ‘dangerous game’ that could send food price inflation soaring

Demand for biofuels is likely to leap by nearly a third this year, which could send food price inflation soaring further and push the world closer to a global food crisis.

More countries are opting to increase biofuel use as the price of oil has jumped to nearly $100 a barrel after the US-Israeli attacks on Iran and the closure of the strait of Hormuz.

Last week, as the war in Iran continued to choke global oil supplies, the UK government announced a 13% increase in the cap on energy prices. But it was another related story on the other side of the world that caught my eye.

In Australia, the energy minister announced a fall of up to 10% in the benchmark electricity price in parts of the country, driven by record levels of renewables and batteries in the power grid.

The March GDP figures, not for the first time, showed that the focus on economic growth seems rather foolish when you place it within the context of the climate crisis. While the economy did grow in the first three months of this year, the big driver was investment in datacentres, which a new report on Wednesday revealed is greatly increasing the risk to the climate and Australia’s environment.

You probably could do worse than say that the March GDP figures suggest Australia’s economic growth will “push up power prices, prolong the use of polluting coal power stations, increase gas generation, and derail the progress we are making towards our climate goals”.

State attorneys general argue $1bn deal to terminate major offshore wind lease off the coast of New York is unlawful

Seven states sued the Trump administration on Tuesday over its decision to cancel a major offshore wind lease off the coast of New York.

In March, federal officials announced they would pay nearly $1bn in taxpayer dollars to French energy firm TotalEnergies in exchange for the company killing plans to erect two offshore windfarms off New York and North Carolina. TotalEnergies agreed to terminate the projects and pledged not to develop any new offshore wind projects in the United States, while investing hundreds of millions of dollars in oil and gas projects.
