Discover the future of wind energy with our in-depth comparison between vertical axis wind turbines (VAWTs) and traditional ...

Offshore wind turbines are trying to reproduce at sea what works on land, write Maurizio Collu & Michael Borg. But it's proving a costly and high maintenance exercise. It's time to switch to new ...

A debate over whether it is best to harness wind energy with horizontal-axis devices or vertical-axis devices has raged for thousands of years. Even how the technologies evolved is under some dispute.

These scale model wind turbines use fixed-pitch blades to evaluate a new vertical axis wind turbine design. Vertical axis wind turbines are easier to install than traditional horizontal axis wind ...

EPFL researchers developed optimal pitch profiles for vertical-axis wind turbines using a genetic learning algorithm. The new pitch profiles resulted in a 200% increase in turbine efficiency and a 77% ...

Coordinates are two numbers used to describe a point's position on a grid. Grids have two axes. The horizontal axis is called the x-axis and the vertical axis is called the y-axis. Coordinates are ...

Descriptive labels on an Excel chart enhance its readability and help you interpret the information the chart contains. Whether naming comes in the form of text, numbers or a combination, both the x ...

Graphs in Microsoft Excel typically chart time on the horizontal axis. Time is the independent variable in most relationships and dependent variables appear on the vertical axis. Some charts, though, ...

Microsoft Excel is well known for creating charts for marketing purposes, and it has features to perform various calculations. Charts are a graphical representation of your data, and they make showing ...
