This is a sort of natural power plant. It's a group of many wind turbines located together in an area that gets steady wind (in open, rural spaces, near mountain passes, even in offshore locations). The turbines collect the wind's energy and convert it to electricity, which can then be sold to the local utility grid. Wind is a renewable, virtually pollution-free source of electricity.
Cherry, maple, oak, elm and other deciduous trees fall into this category of wood. They are slower-growing trees than softwood conifers such as pine, and are sources of durable, valuable, and undeniably good-looking timber for flooring and furniture. The market for hardwoods has led to damaging forestry practices the world over, but some logging companies harvest more gently; when shopping for hardwood products, look for those certified by Forest Stewardship Council (FSC)-a sign that the wood came from a sustainable, well managed forest. Salvaged hardwood (rescued from buildings scheduled for demolition, for example) is another tree-friendly choice.
