Building a better turbine

Imagine a world in which half of our electricity is generated renewably by offshore wind farms. Now imagine a powerful hurricane hitting the coast where that farm is located. If developers, engineers and policy makers haven't ...

Shop online? Ways to reduce damage to the environment

Toothpaste delivered in two days is convenient, but not so great for the environment. After you click buy, online orders leave warehouses to be loaded on gas-guzzling jets or trucks. And returns are a problem, too, since ...

Study offers insights on wind development costs, taxes

A new analysis of state taxation policies regarding wind energy in the West shows New Mexico is the lowest-cost state for wind farm development, followed by Montana, Colorado and Wyoming.

Improved hybrid models for multi-step wind speed forecasting

To mitigate global warming by reducing emissions, wind is widely expected to become an alternative source of energy. Wind power generation uses the surface atmosphere, where movement blows the wind turbine to generate the ...

How to neutralise your greenhouse gas footprint

With time running out for us to make deep reductions in greenhouse emissions, you may well be wondering what you personally can do to minimise your own greenhouse footprint.

Fixing the environment: when solutions become problems

In a world where climate change, air and water pollution, biodiversity loss, water scarcity, ozone depletion, and other environmental problems overlap, a fix in one arena can cause trouble in another.

Wind farm

A wind farm is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage transmission system. A large wind farm may consist of a few dozen to several hundred individual wind turbines, and cover an extended area of hundreds of square miles (square kilometers), but the land between the turbines may be used for agricultural or other purposes. A wind farm may be located off-shore to take advantage of strong winds blowing over the surface of an ocean or lake.
