Large Wind Farms are Great
darinselby, I disagree with you about large wind farms. First of all, properly located wind farms kill 10s of thousands of birds, but glass windows in our homes kill millions of birds every year in the US. You point out 20% loss of power to the grid, but think about how efficient could your average family's windmill really be when in most cases they won't be well located and the smaller windmills won't be as efficient nor as cost-efficient for installation. My home has the space but is surrounded by woods that block the wind. Most people live in apartments or have tiny yards. And higher winds are concentrated in certain regions. But rooftops are plentiful: If you really want something at your home, probably solar power will be better. Solar water heating is somewhere around 50% efficient and is still cheaper than solar-electric--but that price will drop as well. You can like decentralizing where it is practical, but your comment was overly upset about big wind farms.
