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?
Useful for CBSE, ICSE, NCERT & International Students Grade : 6 Subject : Science Lesson : Work and Energy Topic: SOURCES OF ENERGY Primary energy sources take many forms, including nuclear energy, fossil energy -- like oil, coal and natural gas – and renewable sources like wind, solar, geothermal and hydropower. These primary sources are converted to electricity, a secondary energy source, which flows through power lines and other transmission infrastructure to your home and business.

Integration of a unit-type cogeneration plant As you indubitably know, large pieces of equipment like a bottle washer consume huge amounts of energy. It doesn't have to be like this! The remedy is to integrate a unit-type cogeneration plant, which as it produces electricity also generates heat, which in its turn can be passed directly to the consumer, which is the bottle washer. The cogeneration plant utilises up to 90 per cent of the fuel or primary energy deployed.
Why are fossil fuels still our predominant source of energy if they cause so much harm to the environment?

Energy is defined as the ability to do work.Though energy may be converted from one form to another, it can not be created or destroyed i.e. total energy in a system remains constant. All forms of energy can be linked with motion.

China’s 13th Five-Year Plan aims to give non-fossil fuels a bigger role in meeting the country’s energy demand. Alternative sources of energy are expected to account for 15% of overall primary energy consumption by 2020. CCTVNEWS takes a look at the measures employed to achieve the goals of this energy revolution.

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...
Describes primary energy sources used to generate electricity and do work. Focus on US consumption and tradeoffs between pro's and con's of each energy source.
Primary energy factors (PEF), often referred to as conversion factors, are required to calculate the total energy consumption including the total chain of energy generation based on the final energy consumption data. In this webinar, different primary energy definitions, accounting methods, and their applications with a focus on electricity and heat generation from renewable energy will be presented. In addition to renewable energy sources, primary energy factors for electricity from waste, nuclear, and imported electricity are also discussed as these can be calculated in different ways. Depending on the methodology used, it will be shown that the resulting PEFs for different energy sources vary significantly.
