The US could double or even quadruple the installed wind power capacity with little change to system-wide efficiency, and the additional capacity would make very small impacts on local climate. This is achieved partly by deploying next generation, larger wind turbines. They repay their lifetime carbon emissions associated with deployment and fabrication in three to seven months of operation. It amounts to nearly 30 years of virtually carbon-free electricity generation.
