According to Treehugger, wind turbines have become the top-selling item at B&Q (the British equivalent to Home Depot) weeks after they first went on sale.
Home owners are rushing to buy them at £1,498 ($2,840 U.S.) a pop.
They have also started selling seven different kinds of solar panels for tile and slate roofs. Some are used to heat water whilst others generate electricity. Next year the store intends to offer products to recycle "grey water" from washing up for use in the garden.
