There are two main types of blades for a wind turbine — ones with a vertical axis and ones with a horizontal axis. Vertical-axis turbines are the kind that you’re most familiar with. They look like giant, minimalist fans with an average of three blades. These only work when they’re ...
Wind turbine towers and nacelles contain quite a bit of metal, and concrete foundations to stop them falling over (a typical turbine has 8000 parts in total), so constructing them does have some environmental impact. Even so, looking at their entire operating lifespan, it turns out that ...
Practical steam turbines come in all shapes and sizes and produce power ranging from one or two megawatts (roughly the same output as a single wind turbine) up to 1,000 megawatts or more (the output from a large power plant, equivalent to 500–1000 wind turbines working at full capacity)....
Why are the most commonly used wind turbines those with three blades? Throughout history, there have been many types of turbines or machines that were used to take advantage of the kinetic energy produced by the wind. Of all of these, the most used and widespread in our days — and likew...
Back in 2019, SKF entered a three-year partnership with the US Department of Energy’s National Energy Laboratory to study wind turbine drivetrains under various conditions. SKF contributes spherical rolling bearings, bearing housing, seals, and condition monitoring technology to the project. ...
Mass flow at the exhaust of a combined- cycle unit in a three-pressure system can be as much as 30% greater than the throttle flow. This is in direct contrast to most units with fired boil- ers, where exhaust flow is about 25% to 30% less than the th...

I think about the dynamics at play in Renewable Energy in three parts. First, Onshore Wind is our most established, profitable business, and it is meeting high customer demand and growing internationally. Second, we're placing technology bets in fast-growing markets. In October, for example, ...
The move could come this month, three EU officials told the FT, as part of broader proposals aimed at boosting Europe’swind industry. Didier Reynders© AFP via Getty Images It would be the second significant action against China is as many months, after commission president Ursula von der ...
According to Sandy Butterfield, principal engineer at the National Renewable Energy Laboratory, end users and owner-operators report their gearboxes generally last five or in some cases only three years. Not surprisingly, engineers are trying to solve this problem. ...
