• What is primary energy?

    Öresundskraft are pleased to present a short film explaining the concept of primary energy, a concept that is beginning to be used more frequently in different contexts. The film aims to briefly explain the concept of primary energy and does not purport to be comprehensive or scientifically based. What is primary energy and why should we use as little of it as possible and focus on using recycled energy instead?

    #oilwire - Oil and gas will be crucial components of the world’s energy future, according to DNV GL’s forecast of the energy transition. While renewable energy will grow its share of the energy mix, oil and gas will account for 44% of world energy supply in 2050, compared to 53% today. Gas will become the largest single source of energy from 2034. DNV GL’s Energy Transition Outlook (ETO), a forecast that spans the global energy mix to 2050, predicts that global demand for energy will flatten in 2030, then steadily decline over the next two decades, thanks to step-changes in energy efficiency. The fossil fuel share of the world’s primary energy mix will reduce from 81% currently to 52% in 2050.

  • Determining primary energy factors for electricity

    A primary energy factor (PEF) for electricity describes the ratio between end-user consumption of electricity and primary energy consumption. In recent years, the EU has implemented regulatory use of PEFs in the energy policy framework. As a result, PEFs now play a role in the regulation of production and consumption of electricity throughout Europe. A key challenge is the lack of professional and/or political agreement on how the PEF shall be determined. Up until today, approaches used to determine PEFs have lacked foundation in objective methodologies, and the discussions have often been plagued by sectorial interest and political goals. Regulatory application of PEFs can create enormous challenges for European authorities and other energy market interests in the future. Depending on th...

    There is no unified approach in European regulation of how to calculate primary energy when assessing energy performance of buildings. Instead, member states can decide on their own method of calculation of primary energy. As the share of renewables will progress towards 2050, the primary energy factors for electricity in Europe will also be subject to changes over time. Related to the energy performance of buildings, the question is in what way different (due to national electricity mix or methodology) and changing (due to increased share of renewable electricity) primary energy factors for electricity influence decisions on a political level and on a level of individual building designs, especially with regard to space heating options (gas vs. electricity).

In this video I discuss the 3 energy systems in the body, atp energy, aerobic energy, anaerobic energy, adenosine triphosphate, creatine phosphate and ways to train the energy systems in the body. The Body’s Energy Systems Energy is needed to produce physical movement, maintain body temperature and keep up with all the metabolic activities in the body. In our bodies, all physical movement relies on the compound adenosine triphosphate, or ATP. Atp is stored in the muscles, so it is immediately available to produce movement. However, storage of ATP in the muscles is limited. So, any movement that lasts longer than a few seconds requires more ATP to be produced. Our bodies have 3 energy systems that can produce ATP energy, the ATP-PCr system, the glycolytic system, or lactic acid system, and the Oxidative system. The first 2 systems are anaerobic systems, meaning oxygen is not required to produce ATP, and the Oxidative system is aerobic, because oxygen is needed for ATP production. The atp-pcr system is based on movements lasting about 10 seconds or less, such as strength power movements like a golf swing, jumps, throwing, or racket serves. These types of quick burst movements can be done with ATP that is stored in the muscles. During Short, Sustained power movements, or any quick bursts such as short sprint, ATP will provide the energy alone for the first few seconds, with a compound called creatine phosphate, or PCr, buffering the ATP for another few seconds. Like ATP, the amount of Pcr is limited, so this system can provide energy for movements up to about 15 seconds in total. This energy system produces ATP very quickly, but not over a long duration. Next, energy demands shift to the glycolytic system. This system relies on the rapid breakdown of carbohydrates. Glucose, which is one of the most basic forms of carbohydrates, is constantly circulating in the bloodstream. Glycogen is a stored form of glucose in the muscles and liver. This blood glucose or glycogen is broken down to create ATP through a process called glycolysis. During this energy supply process, a substance called lactate is formed, and hydrogen ions are released. It is believed that the accumulation of these hydrogen ions in the muscle causes the muscle to become more acidic, contributing to fatigue and a burning sensation. Exercises that are performed at maximum rates for between 1 and 2 minutes, such as a 200 yard dash, depend heavily upon the lactic acid system for ATP energy. This energy system produces ATP very quickly, but again, not over a long duration. The oxidative system involves the use of oxygen. Through 2 complex metabolic processes, the Krebs cycle or citric acid cycle, and the electron transport chain, ATP is produced. This energy system, with all of its processes can’t produce ATP nearly as quickly as the first 2 systems; however, this system can produce ATP for a much longer duration. This system can use carbs, fats, or if necessary, even protein, however, fats and proteins have to be broken down, so when the system uses them, the process becomes longer. This system is used for longer duration activities, such as a bike ride, or long run. The chart on the screen shows an estimate of the % of energy used from each system along with time plotted at the top, you can see the atp cp system dominates at the beginning, then glycolysis becomes the dominate energy provider, and then energy really relies on the oxygen system. Here are two other charts; the one on the left shows an estimated rate of ATP production per second for each system. It shows the rate for carbs and fats for the oxygen system. You can see how much more rapidly the ATP pcr and glycolysis systems are at ATP production. On the left is a chart showing the aerobic ATP production for trained and untrained people, showing the benefits of well trained persons, as they don’t run out of energy easily. Each of these systems can be trained to be more productive. By changing your workout routines, doing explosive moves like box jumps you can improve system 1. By doing circuit routines, going from one exercise to the next with little to no rest in between and using lighter weights you can train system 2. And, by doing a 20 to 30 minute cardio session of low to moderate intensity, like walking, jogging or biking, you can improve system 3. Its good practice to train all 3 systems, by altering your workout routines. The body is amazing, and it adapts very quickly. Changing up routines also provides mental stimulation, which helps overall health, and can help people stay motivated to workout regularly. Remember this folks, hit your body as differently as possible, as often as possible.

This video represents a good explanation of What is energy for kids. You will gonna learn about Energy Sources for kids, How we use Energy ( how to save energy ) and a brief understanding about different types of Renewable Energy resources as well as the nonrenewable ones. ► What is energy ? The best definition of energy, that every children should know, is that the Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. We use energy to move cars along roads and boats through water, to cook food on stoves, to make ice in freezers, and to light our homes. Energy comes in different forms: Heat (thermal), Light (radiant), Motion (kinetic), Electrical, Chemical, Nuclear energy and Gravitational Energy. People use energy for everything from making a jump shot to sending astronauts into space. There are two types of energy: ( Stored (potential) energy + Working (kinetic) energy ). For example, the food a person eats contains chemical energy, and a person's body stores this energy until he or she uses it as kinetic energy during work or play. Energy sources can be categorized as renewable or nonrenewable When people use electricity in their homes, the electrical power was probably generated by burning coal, by a nuclear reaction, or by a hydroelectric plant on a river, to name just a few sources. Therefore, coal, nuclear, and hydro are called energy sources. When people fill up a gas tank, the source might be petroleum refined from crude oil or ethanol made by growing and processing corn. Energy sources are divided into two groups: 1- Renewable (an energy source that can be easily replenished) 2- Nonrenewable (an energy source that cannot be easily replenished). ► Renewable energy and nonrenewable energy for kids : Renewable and nonrenewable energy sources can be used as primary energy sources to produce useful energy such as heat or used to produce secondary energy sources such as electricity. When people use electricity in their homes, the electrical power was probably generated from burning coal or natural gas, a nuclear reaction, or a hydroelectric plant on a river, to name a few possible energy sources. The gasoline people use to fuel their cars is made from crude oil (nonrenewable energy) and may contain a bio-fuel (renewable energy) like ethanol, which is made from processed corn. ► Moreover, you will gonna learn What is renewable energy for kids ? There are five main renewable energy sources: 1- Solar energy from the sun 2- Geothermal energy from heat inside the earth 3- Wind energy 4- Biomass from plants 5- Hydro power from flowing water ► What is Nonrenewable energy ? Most of the energy consumed in the United States is from nonrenewable energy sources: ( Petroleum products - Hydrocarbon gas liquids - Natural gas - Coal - Nuclear energy ). Crude oil, natural gas, and coal are called fossil fuels because they were formed over millions of years by the action of heat from the earth's core and pressure from rock and soil on the remains (or fossils) of dead plants and creatures like microscopic diatoms. Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal. Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. By watching this video, you will gonna learn how to conserve energy resources ( energy saving ) by understanding how energy conservation mechanism work as well as much knowledge about alternative energy resources. Enjoy watching and have a great time learning about energy sources for children.

A primary energy factor (PEF) for electricity describes the ratio between end-user consumption of electricity and primary energy consumption. In recent years, the EU has implemented regulatory use of PEFs in the energy policy framework. As a result, PEFs now play a role in the regulation of production and consumption of electricity throughout Europe. A key challenge is the lack of professional and/or political agreement on how the PEF shall be determined. Up until today, approaches used to determine PEFs have lacked foundation in objective methodologies, and the discussions have often been plagued by sectorial interest and political goals. Regulatory application of PEFs can create enormous challenges for European authorities and other energy market interests in the future. Depending on the case, the determination of a PEF may push end-users to alter their consumption of energy, decisions on energy efficiency and/or choice of energy fuels. Thus, PEFs may affect European countries’ ability to achieve long-term energy- and climate goals. In this webinar, Andreas Aamodt presentes from a framework to determine PEFs for electricity. He also discusses to what degree such conversion factors are appropriate or required for use in the context of EU energy policy.

There is no unified approach in European regulation of how to calculate primary energy when assessing energy performance of buildings. Instead, member states can decide on their own method of calculation of primary energy. As the share of renewables will progress towards 2050, the primary energy factors for electricity in Europe will also be subject to changes over time. Related to the energy performance of buildings, the question is in what way different (due to national electricity mix or methodology) and changing (due to increased share of renewable electricity) primary energy factors for electricity influence decisions on a political level and on a level of individual building designs, especially with regard to space heating options (gas vs. electricity). From a point of view of making the electricity supply more flexible, it could be desirable to increase the share of electricity for heating. The objective of this work was to assess to what extent this is stimulated (or hampered) by changing primary energy factors in building regulation of a number of countries. Introductory comments on primary energy factors and the EPBD Primary energy factors of seven countries in the EU: • FranceGermanyThe NetherlandsPolandSpainSweden • UK Primary energy factors estimated evolution at 2020 and 2050 horizons, using the same calculation methods for all countries, based on the energy sources that can be expected to be in the national mix of these countries in 2020 and 2050, according to different scenario's. Implications of changing primary energy factors for technologies used in the building sector and recommendations on how to deal with primary energy factors in the EPBD in the short term and the longer term. The webinar will be given by Edith Molenbroek and Thomas Boermans from Ecofys.
