U.S. Energy in the 21St Century: a Primer
U.S. Energy in the 21st Century: A Primer March 16, 2021 Congressional Research Service https://crsreports.congress.gov R46723 SUMMARY R46723 U.S. Energy in the 21st Century: A Primer March 16, 2021 Since the start of the 21st century, the U.S. energy system has changed tremendously. Technological advances in energy production have driven changes in energy consumption, and Melissa N. Diaz, the United States has moved from being a net importer of most forms of energy to a declining Coordinator importer—and a net exporter in 2019. The United States remains the second largest producer and Analyst in Energy Policy consumer of energy in the world, behind China. Overall energy consumption in the United States has held relatively steady since 2000, while the mix of energy sources has changed. Between 2000 and 2019, consumption of natural gas and renewable energy increased, while oil and nuclear power were relatively flat and coal decreased. In the same period, production of oil, natural gas, and renewables increased, while nuclear power was relatively flat and coal decreased. Overall energy production increased by 42% over the same period. Increases in the production of oil and natural gas are due in part to technological improvements in hydraulic fracturing and horizontal drilling that have facilitated access to resources in unconventional formations (e.g., shale). U.S. oil production (including natural gas liquids and crude oil) and natural gas production hit record highs in 2019. The United States is the largest producer of natural gas, a net exporter, and the largest consumer. Oil, natural gas, and other liquid fuels depend on a network of over three million miles of pipeline infrastructure. -

Be Aware of Potential Risk of Dam Failure in Your Community
Be Aware of Potential Risk of Dam Failure in Your Community Approximately 15,000 dams in the United States are classified as high-hazard potential (HHP), meaning that their failure could result in loss of life. Dams can fail for a number of reasons, including overtopping caused by floods, acts of sabotage, or structural failure of materials used in dam construction. The worst dam failure in the United States occurred in 1889 in Johnstown, Pennsylvania. Over 2,200 died, with many more left homeless. Dams present risks but they also provide many benefits, including irrigation, flood control, and recreation. Dams have been identified as a key resource of our national infrastructure that is vulnerable to terrorist attack. States have the primary responsibility for protecting their populations from dam failure. Of the approximately 94,400 dams in the United States, State governments regulate about 70 percent. About 27,000 dams throughout our Nation could incur damage or fail, resulting in significant property damage, lifeline disruption (utilities), business disruption, displacement of families from their homes, and environmental damage. The most important steps you can take to protect yourself from dam failure are to know your risk. Contact government offices to learn if an Emergency Action Plan (EAP) is in place and to evacuate when directed by emergency response officials. An EAP is a formal document that identifies potential emergency conditions at a dam and specifies preplanned actions to be followed by the dam owner to reduce property damage and loss of life. The plan may save lives and property damage through timely evacuations of those who live, work, or enjoy recreation near a high-hazard potential dam. -
Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics
Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics GEL 230 – Ecogeomorphology University of California, Davis Derek Roberts March 2nd, 2016 Abstract: At the upstream end of the Grand Canyon, the Glen Canyon Dam has changed the Colorado River from a run-of-the-river flow to a deep, summer-stratified reservoir. This change in flow regime significantly alters the temperature regime of the Colorado River. Seasonal temperature variation, once ranging from near to almost , is now limited to 7 . The lack of warm summer temperatures has prevented spawning of endangered 0℃ 30℃ humpback chub in the Colorado River. Implementation of a temperature control device, to − 14℃ allow for warmer summer releases to mitigate negative temperature effects on endangered fish, was considered by the federal government. Ultimately, this proposal was put on indefinite hold by the Bureau of Reclamation and U.S. Fish and Wildlife Service due to concerns of cost and unintended ecological consequences. The low-variability of the current dam-induced Colorado River temperature regime will continue into the foreseeable future. Agencies are reviewing humpback chub conservation efforts outside of temperature control. Keywords: Colorado River, Grand Canyon, Glen Canyon Dam, thermal dynamics 1.0 Introduction Temperature in natural water bodies is a primary driver of both ecological and physical processes. Freshwater plant and animal metabolisms are heavily affected by temperature (Coulter 2014). Furthermore, the thermal structure of a water body has significant impacts on the physical processes that drive ecosystem function (Hodges et al 2000); fluid dynamics drive transport of nutrients, oxygen, and heat. Human action, often the introduction of dams or industrial cooling systems, can alter the natural thermal regimes of rivers and lakes leading to reverberating impacts throughout associated ecosystems. -
(Hydropower) Technology in South African Narrow-Reef Hard-Rock Mines
The Southern African Institute of Mining and Metallurgy Platinum 2012 P. Fraser THE USE OF HIGH-PRESSURE, WATER-HYDRAULIC (HYDROPOWER) TECHNOLOGY IN SOUTH AFRICAN NARROW-REEF HARD-ROCK MINES P. Fraser Hydro Power Equipment (Pty) Ltd Abstract This paper examines the new water-hydraulic (hydropowered) drill rigs that have been developed and proven in the last decade primarily in tabular, shallow-dipping, narrow-reef hard-rock South African mines. These include drill rigs for flat-end tunnel development, narrow inclined raises and winzes, large inclines and declines and longhole-based developments such as ore passes and vent raises. The hydropower technology rigs offer advantages both in safety and performance over traditional compressed-air-powered, hand-held development, and are generally more cost-effective than imported oil electro-hydraulic drill rigs. Furthermore, hydropowered rigs are inherently energy-efficient. The benefits of hydropower are discussed and a ‘comprehensive development model’ is presented which demonstrates that ore-bodies can be accessed in significantly shorter times. ‘Localized’ half level hydropower systems are introduced and a range of ancillary equipment available is listed. Introduction According to Neville Nicolau, CEO of Anglo Platinum, ’Safety is our moral licence to operate’ and, ’if we don’t get our safety right, then you must expect society to take away our licence to operate, and then we would be responsible for closing mines and destroying work 1. While the long-term trend in the Fatal Injury Frequency Rate (FIFR) is downward, fatalities are not acceptable to any of the stakeholders in the mining industry or investor community. Safety is therefore a non-negotiable imperative. -
The Contribution of Hydropower Reservoirs to Flood Control in the Austrian Alps
Ilydrology in Mountainous Regions. II - Artificial Reservoirs; Water and Slopes (Proceedings of two Lausanne Symposia, August 1990). IAHS Publ. no. 194,1990. The contribution of hydropower reservoirs to flood control in the Austrian Alps W. PIRCHER Tiroler Wasserkraftwerke Aktiengesellschaft (TIWAG) Landhausplatz 2, A-6o2o Innsbruck, Austria ABSTRACT A considerable improvement to flood control is a significant - and free - additional utility accruing to the general public from the construction of hydropower storage reservoirs. By way of illustration, the author presents a comparative study on the basis of a number of flood events in valleys influenced by storage power plants. INTRODUCTION Austria has approximately thirty major storage reservoirs built by hy dropower companies and operated on a seasonal basis. Since they tend to be located at high altitudes, total stored energy from a combined active storage of 1.3oo hm^ is over 3.5oo GWh for winter and peak power generation, and this forms the backbone of electricity generation in Austria. Taking into account also the smaller reservoirs for daily and weekly storage, approximately 31% of the country's present annual total hydroelectric generation of 34.ooo GWh is controlled by reservoir sto rage, with the high degree of control and flexibility this offers. The primary goal in the construction of all storage power schemes in Austria, and the only source of subsequent earnings for the hydro- power companies, is of course electricity generation, but such schemes also involve a whole series of additional utilities that accrue to the general public free of charge. As a rule, significant improvements in flood control are the most important of these spin-offs, although be nefits to the local infrastructure and tourism as well as a markable increase of flow during the winter period are not to be underestimated, either. -
Hydroelectric Power -- What Is It? It=S a Form of Energy … a Renewable Resource
INTRODUCTION Hydroelectric Power -- what is it? It=s a form of energy … a renewable resource. Hydropower provides about 96 percent of the renewable energy in the United States. Other renewable resources include geothermal, wave power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up resources to create electricity nor do they pollute the air, land, or water, as other powerplants may. Hydroelectric power has played an important part in the development of this Nation's electric power industry. Both small and large hydroelectric power developments were instrumental in the early expansion of the electric power industry. Hydroelectric power comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity. Hydroelectric power is important to our Nation. Growing populations and modern technologies require vast amounts of electricity for creating, building, and expanding. In the 1920's, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate and hydroelectric power presently supplies about 10 percent of the electrical generating capacity of the United States. Hydropower is an essential contributor in the national power grid because of its ability to respond quickly to rapidly varying loads or system disturbances, which base load plants with steam systems powered by combustion or nuclear processes cannot accommodate. Reclamation=s 58 powerplants throughout the Western United States produce an average of 42 billion kWh (kilowatt-hours) per year, enough to meet the residential needs of more than 14 million people. -
A Case Study in the Dudh Koshi Basin of Nepal

Bernardino 145, 24122 Bergamo, Italy 3 Department of Energy Engineering (DENG), Politecnico di Milano, Campus-Bovisa, Lambruschini, 4a, 20156 Milano, Italy; [email protected] * Correspondence: [email protected] Received: 20 July 2020; Accepted: 16 September 2020; Published: 19 September 2020 Abstract: In spite of the very large hydropower potential given from the melting snow and ice of Himalayas, Nepal’s population has little hydropower production. The high use of fossil fuels and biomasses results in measurable air pollution, even in the mountain areas. Hydropower planning and implementation, in the face of the changing climate, is therefore paramount important. We focus here on Nepal, and particularly on the Dudh Koshi river basin, with a population of ca. 170,000 people, within an area with large potential for hydropower production. Our main objectives are to (i) preliminarily design a local hydropower grid based on a distributed run of river ROR scheme, and (ii) verify the resilience of the grid against modified hydrology under perspective climate change, until the end of the century. To do so, we set up and tune the Poli-Hydro semi-distributed glacio-hydrological model, mimicking the complex hydrology of the area. We then modify a state of the art algorithm to develop and exploit a heuristic, resource-demand based model, called Poli-ROR. -
Underground Pumped-Storage Hydropower (UPSH) at the Martelange Mine (Belgium): Underground Reservoir Hydraulics

However, PSH cannot always be constructed due to topographic, environmental, and societal constraints, among others. Underground pumped storage hydropower (UPSH) has recently gained popularity as a viable alternative and may utilize abandoned mines for the construction of the lower reservoir in the underground. Such underground mines may have complex geometries and the injection/pumping of large volumes of water with high discharge could lead to uneven water level distribution over the underground reservoir subparts. This can temporarily influence the head difference between the upper and lower reservoirs of the UPSH, thus affecting the efficiency of the plant or inducing structural stability problems.
