Energy-conscious households will get discount crates. : Households with rooftop solar panels can now be paid in beer for their excess power under a scheme in Australia. Asahi Group’s Carlton and United Breweries (CUB) are offering cans of bitter in exchange for solar power, in what the companies involved believe to be a world first. For every A$30 (£17) of solar credit a household generates, they can get 24 cans of beer (known as a slab in Australia), CUB said. The Victoria Bitter exchanged by CUB is worth A$50 in store.
