The idea of a new coal-fired power station in the town has been a useful political tool but few experts think it necessary, or viable

The only physical trace of Shine Energy, which wants to build a $2bn coal-fired power station in north Queensland, is a small post office box next to an Asian grocer at a suburban Brisbane shopping complex. The same mailbox is shared by more than a dozen online businesses, including the maker of a metal card that spuriously claims to improve the quality of wine.

Company documents show Shine Energy is worth a nominal $1,000 on paper. It has no registered financial obligations, and no physical office at its listed address.

German teenager is due to speak at US rightwing conference CPAC

A young campaigner who has been hailed by climate sceptics as the right’s answer to Greta Thunberg has previously described a white nationalist who appeared to promote “white genocide” theories as one of her “inspirations”.

Fat from larvae could be a more sustainable alternative to dairy, say researchers

Scientists at Ghent University in Belgium are experimenting with larva fat to replace butter in waffles, cakes and cookies, saying using grease from insects is more sustainable than dairy produce.

The researchers soak black soldier fly larvae in a bowl of water, put it in a blender to create a smooth greyish dollop and then use a kitchen centrifuge to separate out insect butter.
