A new approach to assessing greenhouse gas emissions from
coal, wind, solar, and other energy technologies paints a much more
precise
picture of cradle-to-grave emissions and should help sharpen decisions
on what
new energy projects to build.

According
to recent research into how wind turbines affect local weather, large
wind farms in certain areas in the United States appear to affect local
land surface temperatures, especially at night. The warming trend was
spatially matched to the locations of wind farms, and caused warming by
nearly three-quarters of a degree Celsius.

A team of Purdue
University researchers
will use a $1.6 million federal grant to advance sensor technology and
computer
simulation tools for tracking and improving the performance and
reliability of
"smart" wind turbines and wind farms.

The
Great Lakes currently have no offshore wind turbines, but several plans
to install them are in the works. Both federal and state governments
are about to announce an agreement to speed up approval of the farms,
which have been delayed by cost concerns and public opposition.

A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates—about 20 times and up to 30 times greater than the current government estimate of 102 GW.

Using a sophisticated weather model, environmental engineers at Stanford University have defined optimal placement of a grid of four wind farms off the United States East Coast. The model successfully balances production at times of peak demand and significantly reduces costly spikes and zero-power events.

The biggest drawback to sources of clean, renewable energy is their intermittency: The wind doesn't always blow, the sun doesn't always shine, and so the power they produce may not be available at all times. A major goal of energy research has been to find ways to help smooth out these erratic supplies. Now the Massachusetts Institute of Technology shows a promising technology that could provide that long-sought way of leveling the load.

By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time. Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power.

Industrial R&D in the energy sector comprises a broad portfolio of
technologies, including fossil, nuclear, and renewable generation; smart
grid or other transmission and distribution; and energy-efficiency
technologies. Energy-related research sponsored by U.S. utilities,
manufacturers, and technology providers will reach nearly $6.7 billion
in 2012.

As the percentage of wind energy contributing to the power grid continues to increase, the variable nature of wind can make it difficult to keep the generation and the load balanced. But recent work by Lawrence Livermore National Laboratory, in conjunction with AWS Truepower, may help this balance through a project that alerts control room operators of wind conditions and energy forecasts so they can make well-informed scheduling decisions.
