Printer Tech Tips—Cause & Effects of Static Electricity in Paper
Printer Tech Tips Cause & Effects of Static Electricity in Paper Problem The paper has developed a static electrical charge causing an abnormal sheet-to- sheet or sheet-to-material attraction which is difficult to separate. This condition may result in feeder trip-offs, print voids from surface contamination, ink offset, Sappi Printer Technical Service or poor sheet jog in the delivery. 877 SappiHelp (727 7443) Description Static electricity is defined as a non-moving, non-flowing electrical charge or in simple terms, electricity at rest. Static electricity becomes visible and dynamic during the brief moment it sparks a discharge and for that instant it’s no longer at rest. Lightning is the result of static discharge as is the shock you receive just before contacting a grounded object during unusually dry weather. Matter is composed of atoms, which in turn are composed of protons, neutrons, and electrons. The number of protons and neutrons, which make up the atoms nucleus, determine the type of material. Electrons orbit the nucleus and balance the electrical charge of the protons. When both negative and positive are equal, the charge of the balanced atom is neutral. If electrons are removed or added to this configuration, the overall charge becomes either negative or positive resulting in an unbalanced atom. Materials with high conductivity, such as steel, are called conductors and maintain neutrality because their electrons can move freely from atom to atom to balance any applied charges. Therefore, conductors can dissipate static when properly grounded. Non-conductive materials, or insulators such as plastic and wood, have the opposite property as their electrons can not move freely to maintain balance. -

Box 378, Ethiopia; [email protected] * Correspondence: [email protected]; Tel.: +32-485659951 or +251-926434658 Received: 12 November 2020; Accepted: 11 December 2020; Published: 15 December 2020 Abstract: Renewable energy sources (RESs) such as wind and solar are frequently hit by fluctuations due to, for example, insufficient wind or sunshine. Energy storage technologies (ESTs) mitigate the problem by storing excess energy generated and then making it accessible on demand. While there are various EST studies, the literature remains isolated and dated. The comparison of the characteristics of ESTs and their potential applications is also short. This paper fills this gap. Using selected criteria, it identifies key ESTs and provides an updated review of the literature on ESTs and their application potential to the renewable energy sector. The critical review shows a high potential application for Li-ion batteries and most fit to mitigate the fluctuation of RESs in utility grid integration sector. -

Electricity Production by Fuel
EN27 Electricity production by fuel Key message Fossil fuels and nuclear energy continue to dominate the fuel mix for electricity production despite their risk of environmental impact. This impact was reduced during the 1990s with relatively clean natural gas becoming the main choice of fuel for new plants, at the expense of oil, in particular. Production from coal and lignite has increased slightly in recent years but its share of electricity produced has been constant since 2000 as overall production increases. The steep increase in overall electricity production has also counteracted some of the environmental benefits from fuel switching. Rationale The trend in electricity production by fuel provides a broad indication of the impacts associated with electricity production. The type and extent of the related environmental pressures depends upon the type and amount of fuels used for electricity generation as well as the use of abatement technologies. Fig. 1: Gross electricity production by fuel, EU-25 5,000 4,500 4,000 Other fuels 3,500 Renewables 1.4% 3,000 13.7% Nuclear 2,500 TWh Natural and derived 31.0% gas 2,000 Coal and lignite 1,500 19.9% Oil 1,000 29.5% 500 4.5% 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2010 2020 2030 Data Source: Eurostat (Historic data), Primes Energy Model (European Commission 2006) for projections.

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. -
Clean Electricity Payment Program a Budget-Based Alternative to a Federal Clean Electricity Standard
Clean Electricity Payment Program A budget-based alternative to a federal Clean Electricity Standard August 2021 Clean energy legislation this year is critical to jumpstart investments in the full set of clean energy solutions required to meet ambitious climate goals. One approach used widely at the state level—a Clean Energy Standard—requires electricity suppliers to use clean energy to meet a growing share of the electricity delivered to their customers. Senator Tina Smith (D-MN) is promoting an alternative approach, the Clean Electricity Payment Program, that relies on incentives to scale-up clean energy investments. What is the Clean Electricity Payment Program (CEPP)? The CEPP is a budget-based alternative to a traditional Clean Electricity Standard (CES) that is designed for passage via the Budget Reconciliation process. It works by providing federal investments and financial incentives to suppliers that deliver electricity directly to retail consumers to supply more clean electricity each year. It is not a regulatory mechanism and does not create a binding mandate. What are the goals of the program? The CEPP is part of an overall package of incentives in the climate portion of the proposed reconciliation package that collectively aims to achieve an 80% nationwide average clean electricity goal by 2030. The CEPP does not require each electricity supplier to achieve this goal. Recognizing that each supplier has a different starting point, the CEPP provides incentives for all suppliers to increase their total clean electricity share each year at an equitable pace. Electricity suppliers that start below the national average are not expected to catch up, and those already meeting very high shares are assigned a smaller annual increase. -
