    Climate change can have an impact on natural and human systems. This is usually the case with renewable-energy-based energy systems, given their close dependence on climate conditions. For instance, long-term changes in temperature, precipitation, and wind shear, among other factors, can affect the operation of existing energy systems and even compromise the viability of new entrepreneurships. Therefore, global climate change can add a significant amount of uncertainty to the already uncertain operation of renewable energy systems. This article gives an overview of the issues related to climate change impacts on hydropower production with a focus on Amazonian regions. View full abstract»

  • Rising Temps, Tides, and Wildfires: Assessing the Risk to California's Energy Infrastructure from Projected Climate Change

    Climate change affects both energy demand and supply through various parameters. These parameters include warmer air and water caused by higher temperatures, changes in the flow of rivers, snowfall and ice accretion, coastal inundation, wildfires, soil conditions, cloudiness, and wind speeds. Increases in energy demand and supply loss create a combined problem for ensuring an adequate supply of fuels and electricity. Projections of these parameters, combined with those of energy demand and supply over the next century, are needed to improve our understanding of the increased vulnerability of the energy sector.

    Coal-fired power plants currently supply nearly half the electricity consumed worldwide. Globally, coal continues to be the primary fuel for affordable and reliable electric power production, due to its low cost and because many countries have indigenous coal resources, providing energy independence.

    To make our energy systems more sustainable and address climate change, society must transition its electricity infrastructure toward zero emission sources over the coming century. Many governments have already accepted this fact, passing ambitious policies to bring renewable energy up to 20% or more of the electricity mix within the next decade. Wind, solar, biomass, wave energy, and hydropower are all likely to grow rapidly as fossil fuels are replaced. This shift will require significant investments in infrastructure for electricity generation, transmission, and distribution. View full abstract»

  • Latin America Goes Electric: The Growing Social Challenges of Hydroelectric Development

    Hydroelectricity was, for many years, one of the main ways to meet the new electricity needs of Latin American countries. This is evidenced by the presence of some of the larger plants worldwide and the high hydroelectric participation in all electricity matrices (Figure 1). Faced with growing prospects for future economic development, an underlying concern is how to respond to the important and growing demands for electricity. In several countries, governments and electric companies have opted to continue with the construction of hydropower plants, especially large-scale ones, as the main means of meeting this challenge. However, major projects formulated in recent years have been put in check by various difficulties, some even stopped. Despite the different political, regulatory, and economic conditions that exist in Latin America, there are common elements in the difficulties faced by these projects. While in the past, large-scale hydroelectricity was the successful response to higher electricity consumption, societies have changed, and this technology faces new cultural, social, and political conditions.

  • Harmonizing AC and DC: A Hybrid AC/DC Future Grid Solution

    It has been over 100 years since Thomas Edison built the first direct current (dc) electricity supply system on 4 September 1882, at Pearl Street in New York City. Many prominent events occurred in the electricity supply industry after that. The first one, ?the war of currents,? started in 1888. Thomas Edison and his dc distribution system were on one side, and George Westinghouse and Nikolai Tesla with the alternating current (ac) system were on other side. The war ?ended? in about 1891 when ac won as the dominant power supply medium. The key behind the ac win was the invention of the transformer that could easily step up medium voltage to high and extra-high voltage for long-distance power transfer from a remote ac generation station to load centers hundreds of kilometers away with lower transmission losses. Transformers can also step down high voltage back to low voltage at load stations to supply the low-voltage equipment. Since the end of the war, ac power systems have been developed and expanded at a tremendous speed from the initial small isolated networks, with each supplying only lighting and motor loads with a few hundreds of customers, to its current scale of super interconnected networks each supplying billions of customers over large geographic areas in one or several countries. The voltage levels and capacities of transmission networks have increased from the first commercialized three-phase ac system with only 2.4 kV, 250 kW in the town of Redlands, California, United States, to the first commercial long-distance, ultra-high-voltage, ac transmission line in China with 1,000 kV, 2,000 MW. Transmission distance has been increased from several miles to over thousands of kilometers (miles). With such major achievements, it is little wonder that the ac power system became the top engineering achievement of the 20th century. Does this mean that dc is gone? The answer is an unambiguous no. What has happened in the past 50 years, such as applications of adva- ced control technologies in conventional power system loads, the power electronics based high-voltage dc (HVdc) transmission, and the additional renewable power sources in low-voltage distribution system, calls for a rethink about dc and ac in electricity supply systems.

  • An AC Pioneer: United Electric Light & Power Company [History]

    It often appears that everything that could be written has been written with regard to the 1890s competition between alternating current (ac) and direct current (dc) electric power systems. Much is inaccurate and, unfortunately, is repeated ad infinitum. One factor that all writers, both popular and scholarly, overlook is that the issue was not resolved in a single event nor was it immediate. The ac systems that ultimately prevailed required decades of research and development prior to universal application. View full abstract»
