Wind farms and wind turbines are strong reflectors of radio waves, which can affect radar and radio systems used by civil and military aviation. The speeds of turbine blades and aircraft are comparable, and it can be difficult to discriminate between them using existing radar systems. Wind turbines may also affect communications, navigation and instrument landing systems. This situation is a brake to wind farm development slowing or stopping exploitation of many giga watts of wind capacity in many countries. Therefore, developing approaches and technologies for the mitigation of the...

Wind energy is a pillar of the strategy for mitigating greenhouse gas emissions and stave off catastrophic climate change, but the market is under tremendous pressure to reduce cost. This results in the need for optimising any new wind turbine to maximise the return on investment and keep the technology profitable and the sector thriving. Optimisation involves selecting the best component out of many, and then optimising the system as a whole.

Wind Turbine System Design: Volume 1: Nacelles, drive trains and verification is a valuable reference for scientists, engineers and...

Clean energy provision and usage has a long history from an engineering perspective. This perspective can help understanding past and current developments at a time of increasing concern about climate change. Over many hundreds of years human beings have been extracting energy from their environment in various ways, many of which could also be acceptable in the future for achieving a lower energy carbon footprint.

This book for engineers, researchers and scientists in the renewable energy industries as well as for advanced students, investors, managers, and engineering historians,...

Hydrogen is a key vector of decarbonized energy systems. It can be used as long term and seasonal storage for electricity itself, as well as in the automotive sector, for space heating and for the chemical industry.

In order to be sustainable, it is vital that hydrogen is generated without carbon emissions. One option is electrocatalysis, which uses electricity to split the water. Other options are photocatalytic and photoelectrochemical technologies that use impinging sunlight directly. Each technique has advantages and shortcomings, and different efficiencies, depending on a range...

Wireless Power Transfer (WPT) serves to transfer power from a grid or storage unit to a device without the need for cable connections. This can be performed by induction, as well as by using radio or microwaves.

The technology is already seeing widespread use; for example, for charging of cell phones and toothbrushes. R&D of WPT, especially inductive and resonance coupling WPT, has been active over recent years. The increased need to decarbonize the transport sector in particular is resulting in growing interest in electric vehicles and their comfortable charging.

Integrating intermittent distributed generation, distributed storage systems, electric vehicles, and flexible loads will present security, stability, and power quality challenges in future smart grids. The amount of data to be processed to face these issues can overwhelm grid operation tools and conventional IT-based applications, limiting situational awareness and decision support. Decentralized and self-organizing technologies can help with that problem. In a self-organizing system, information processing is based on local interactions of its elementary parts (dynamic agents), enabling...
