Hydropower Policy In The United States
Hydropower policy in the United States includes all the laws, rules, regulations, programs and agencies that govern the national hydroelectric industry. Federal policy concerning waterpower developed over considerable time before the advent of electricity, and at times, has changed considerably, as water uses, available scientific technologies and considerations developed to the present day; over this period the priority of different, pre-existing and competing uses for water, flowing water and its energy, as well as for the water itself and competing available sources of energy have changed. Increased population and commercial demands spurred this developmental growth and many of the changes since, and these affect the technology's use today. Federal policies regarding the national water resources, within which hydropower exists, were already well-established long before modern electricity was known to exist; as such, previous uses and decisions, as well as government policies and ...

Department Of Commerce
The United States Department of Commerce (DOC) is an United States federal executive departments, executive department of the Federal government of the United States, U.S. federal government. It is responsible for gathering data for business and governmental decision making, establishing industrial standards, catalyzing economic development, promoting foreign direct investment, and safeguarding national economic security. The Department of Commerce is one of four federal agencies authorized to appoint personnel in the United States Foreign Service, and its NOAA Corps — formerly the Coast and Geodetic Survey Corps — is one of the eight branches of the uniformed services of the United States. During a large-scale disaster or catastrophe, it assumes the coordinating responsibilities for the economic recovery support function under the national disaster recovery framework. Since 2023, it has led U.S. government activities related to safe artificial intelligence development an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Flood Control
Flood management or flood control are methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the ''structural'' type (i.e. flood control) and of the ''non-structural'' type. Structural methods hold back floodwaters physically, while non-structural methods do not. Building hard infrastructure to prevent flooding, such as flood walls, is effective at managing flooding. However, it is best practice within landscape engineering to rely more on soft infrastructure and Nature-based solutions, natural systems, such as marshes and Floodplain, flood plains, for handling the increase in water. Flood management can include ''flood risk management,'' which focuses on measures to reduce risk, vulnerability and exposure to flood disasters and providing risk analysis through, for example, flood ris ...

Wastewater
Wastewater (or waste water) is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration". In everyday usage, wastewater is commonly a synonym for sewage (also called domestic wastewater or municipal wastewater), which is wastewater that is produced by a community of people. As a generic term, wastewater may also describe water containing contaminants accumulated in other settings, such as: * Industrial wastewater: waterborne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment. * Cooling water, is released with potential thermal pollution after use to condense steam or reduce machinery ...

Renewable Energy
Renewable energy (also called green energy) is energy made from renewable resource, renewable natural resources that are replenished on a human lifetime, human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider Nuclear power proposed as renewable energy, nuclear power a renewable power source, although this is controversial, as nuclear energy requires mining uranium, a nonrenewable resource. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can heat pump, move heat and Electric vehicle, vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, ''contro ...

Water Resources
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either Fresh water, freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water (wastewater) or Desalination, desalinated water (seawater). 97% of the water on Earth is saline water, salt water and only three percent is fresh water; slightly over two-thirds of this is frozen in glaciers and polar climate, polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and ice, frozen water. People use water resources for agriculture, agricultural, Industry (economics), industrial and household activities. Water resources are under threat from multiple issues. There is water scarcity, water p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potable Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Energy Policy Act Of 2005
The Energy Policy Act of 2005 () is a federal law signed by President George W. Bush on August 8, 2005, at Sandia National Laboratories in Albuquerque, New Mexico. The act, described by proponents as an attempt to combat growing energy problems, changed US energy policy by providing Energy subsidies#Allocation of subsidies in the United States, tax incentives and loan guarantees for energy production of various types. The most consequential aspect of the law was to greatly increase ethanol production to be blended with gasoline. The law also repealed the Public Utility Holding Company Act of 1935, effective February 2006. Provisions General provisions * The Act increases the amount of biofuel (usually ethanol) that must be mixed with gasoline sold in the United States to by 2006, by 2009 and by 2012; two years later, the Energy Independence and Security Act of 2007 extended the target to by 2022. * Under an amendment in the American Recovery and Reinvestment Act of 2009, ...

Loan Guarantee
A loan guarantee, in finance, is a promise by one party (the guarantor) to assume the debt obligation of a borrower if that borrower defaults. A guarantee can be limited or unlimited, making the guarantor liable for only a portion or all of the debt. Private loan guarantees There are two main types: # Guarantor mortgages # Unsecured guarantor loan Guarantor mortgages Popular with young borrowers who do not have a large deposit saved and need to borrow up to 100% of the property value to purchase a property. Generally, their parents will provide a guarantee to the lender to cover any shortfall in the event of default. There are three main types # Guarantor Mortgage: – generally, a parent or close family member will guarantee the mortgage debt and will cover the repayment obligations should the borrower default. # Family offset mortgage: typically, a parent or grandparent will put their savings into an account linked to the borrower’s mortgage. They do not get any intere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tax Credit
A tax credit is a tax incentive which allows certain taxpayers to subtract the amount of the credit they have accrued from the total they owe the state. It may also be a credit granted in recognition of taxes already paid or a form of state "discount" applied in certain cases. Another way to think of a tax credit is as a rebate. Refundable vs. non-refundable A refundable tax credit is one which, if the credit exceeds the taxes due, the government pays back to the taxpayer the difference. In other words, it makes possible a negative tax liability. For example, if a taxpayer has an initial tax liability of $100 and applies a $300 tax credit, then the taxpayer ends with a liability of –$200 and the government refunds to the taxpayer that $200. With a non-refundable tax credit, if the credit exceeds the taxes due then the taxpayer pays nothing but does not receive the difference. In this case, the taxpayer from the example would end with a tax liability of $0 (i.e. they could ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
