Are wind turbines truly safe?

What we can't see from Kingston, but what one island neighbour told me is among the biggest changes to their lives, is the noise. When the wind is up, "it sounds like a jet engine coming through -- and they're not all up and running yet."

When lightning strikes wind turbines

This has been known to fry wind turbines. With snow, ice and frigid weather, winter creates complications for renewable energy, as I wrote last week. But for Ralph Brokaw, a Wyoming rancher with both cows and wind turbines on his land, the worst hazard is not the ice that his blades can throw off in the winter. Rather, it is lightning strikes on the towers.

In hurricane, windmill blades could be danger for nuclear plant

The discussion on the proposed windmills on our coast seems to have ignored the serious potential of devastating damage that these structures could cause. Although they "would be designed to withstand hurricane-force winds" it is doubtful that they could be engineered to be completely secure in a Category 3-4 or 5 hurricane or a tornado. The blades of these turbines are designed to produce optimum benefits from the wind, which means to me that if they were detached in a hurricane or tornado, they would become lethal missiles that could slice through not only nearby homes, but would pose a grave danger to the nuclear power plant facilities as well.

The wind energy industry has been growing at nearly 30 percent per year for the last decade. The heavy push for more green energy has created a gold rush of sorts...which means buyer beware ...

News on the wind turbine front just keeps coming in

The talk in the local community is that five of the 12 turbines at Toora are now shut down because of equipment failure, the warrantee period has expired and they can't get parts. This wind farm is not particularly old and it's now limping along with a 42% reduction in power output. It's probably a good time to get this junk off the Toora hills....... This mucking around with turbines all adds to the cost of something that is nothing more than a hoax, which would all be pretty funny if it wasn't subsidised by the public purse.
