The electric century : how the taming of lightning shaped the modern world
\"This book is about how electricity has profoundly changed the way we live, work, and play. Some twenty topics are covered, with an abundance of graphs and images to build a comprehensive picture. Each looks at the developments, and the people who initiated them, together with how one led to the next and their subsequent impact on society. Topics include electric supply, lighting through X-rays, and all those appliances that make our homes so comfortable. Most homes at the end of the twentieth century were full of electrical equipment, much of which was regarded as essential. It ran from lights, washing machines, fridges, freezers, kettles, telephones and so on, to the more subtle things such as wipers and starter motors on cars. In 1900, in all but a tiny minority of houses, there were none of these things. It is very difficult for us now to imagine a world without electrical equipment everywhere, and yet it has only taken a century. The Electric Century examines how we got from then to now. The nineteenth is often described as the century of steam from the impact it had on employment and transport, and The Electric Century makes a similar claim as the description of the twentieth. Electricity and the equipment using it are so pervasive that they have affected every corner of modern life\"-- Provided by publisher.

City-level analysis of subsidy-free solar photovoltaic electricity price, profits and grid parity in China
In recent years, China has become not just a large producer but a major market for solar photovoltaics (PV), increasing interest in solar electricity prices in China. The cost of solar PV electricity generation is affected by many local factors, making it a challenge to understand whether China has reached the threshold at which a grid-connected solar PV system supplies electricity to the end user at the same price as grid-supplied power or the price of desulfurized coal electricity, or even lower. Here, we analyse the net costs and net profits associated with building and operating a distributed solar PV project over its lifetime, taking into consideration total project investments, electricity outputs and trading prices in 344 prefecture-level Chinese cities. We reveal that all of these cities can achieve—without subsidies—solar PV electricity prices lower than grid-supplied prices, and around 22% of the cities’ solar generation electricity prices can compete with desulfurized coal benchmark electricity prices.
Although solar photovoltaic use grows rapidly in China, comparison with grid prices is difficult as photovoltaic electricity prices depend on local factors. Using prefecture-level data, Yan et al. find that 100% of user-side systems can achieve grid parity, while 22% can produce electricity cheaper than coal-based power plants.

Power for all
India has led the developing world in addressing rural energy problems. By late 2012, the national electricity grid had reached 92 percent of India s rural villages, about 880 million people. In more remote areas and those with geographically difficult terrain, where grid extension is not economically viable, off-grid solutions using renewable-energy sources for electricity generation and distribution have been promoted. The positive results of the country s rural energy policies and institutions have contributed greatly to reducing the number of people globally who remain without electricity access. Yet, owing mainly to its large population, India has by far the world s largest number of households without electricity. More than one-quarter of its population or about 311 million people, the vast majority of whom live in poorer rural areas, still lack an electricity connection; less than half of all households in the poorest income group have electricity. Among households with electricity service, hundreds of millions lack reliable power supply.

Electrical Coronas
Electrical Coronas: Their Basic Physical Mechanisms explores the fascinating and often overlooked phenomenon of electrical corona discharges, which, despite their seemingly inconspicuous nature, play a crucial role in various industrial and scientific processes. Ranging from small, imperceptible glow discharges in air to larger glowing spheres such as St. Elmo's fire, coronas are vital to many applications, including high-tension power lines, air pollution control, and electrochemical processes. These discharges also contribute to important technologies like Geiger counters and are utilized in processes such as dry-process ore beneficiation and the discharging of statically electrified aircraft. The study of coronas offers valuable insights into electrical breakdown in gases, a key area of physics that has advanced significantly since the 1930s with improved experimental techniques. The book provides an in-depth analysis of corona discharges, emphasizing their importance in understanding the processes of electrical breakdown in gases. By examining these discharges, which occur in highly asymmetrical electrical fields, researchers can isolate and study the mechanisms of breakdown that are often obscured in more complex discharge processes. This work is essential for both theoretical advancements in gaseous electronics and practical applications in engineering. Key discoveries, such as the Hermstein glow discharge and insights into the streamer mechanism of electrical sparks, are discussed in detail. The book also delves into the applications of corona discharges in devices like Geiger counters and the propagation of breakdown in coaxial cylindrical geometries, making it an invaluable resource for those studying electrical discharges and their practical implications.
