If you’ve been thinking about getting an air fryer recently, or have dusted off the slow cooker gift you used twice and then banished to the back of the cupboard, then you’re not alone. Soaring energy prices are pushing many people to think creatively about how to save gas and electricity.

If you’re confused about which kitchen appliances can really save you money, product design and energy expert Amin Al-Habaibeh has carried out some mini-experiments in his own kitchen to compare the energy saving specs of air fryers, thermos, slow and pressure cookers with conventional saucepans. He’s even worked out how many months it could take to break even on your investment if you fork out for a new appliance. Meanwhile, my strategy for dealing with the energy crisis has so far been making myself a strong cup of tea every time my monthly bill arrives and fretting about what will happen if I ignore the minimum fill level on my kettle.

Other people are taking a more active approach than me to the big issues facing society. For example, protest group Just Stop Oil recently thew soup at Van Gogh’s Sunflowers painting in the National Gallery in London. A cognitive psychologist gave us their view on whether radical action can do more harm than good. And if you’re losing sleep over the chaos gripping the UK financial markets, read about research showing why taking some exercise might help.
