Energy requirement and efficiency

Energy efficiency is introduced as using less energy for achieving the same job that helps to reduce energy bills and also reduce pollution. Energy requirements are the optimum number of energies that is required for doing a job efficiently thus energy efficiency and energy requirements are correlated. Energy efficiency is a part of sustainable energy policy. Energy efficiency can be achieved using renewable energy sources rather than fuel energy sources. It helps to reduce the cost of fuels and also makes the environment better as these are pollution-free. Renewable energy sources that can be used to increase energy efficiency include solar energy, wind or hydro energy or energy from biodegradable composts. 

Energy requirement and efficiency

Energy requirements are the optimum amount of energy that is required for doing a job properly, reducing energy usage below the energy requirement results negatively as it reduces energy efficiency. Improving energy efficiencies in industry is the main concern due to the oil crisis and increasing cost of natural fuel. Lower energy use helps to reduce monthly energy consumption that helps to reduce electric bills and makes energy affordable for both homes and industries. Most of the energy-saving devices cost more to buy in the short term. It requires investment but in the long-term, it provides a huge amount of cost savings by reducing energy consumption. 

Energy requirement

A large amount of energy is used by industries for manufacturing products among them Chemical industries produce thousands of products and small amounts of chemical products make up a large amount of energy consumption. Production of Ammonia, ethylene, and alkaline required huge energies. Energy requirements vary from industry to industry according to their manufacturing products. Metal Industry is the second huge energy consumption industry that requires a higher amount of energy for melting hard metals such as Iron and Zinc. 

Efficiency in  management

Energy management is a process that optimizes energy consumption to converge usage in a building. These management includes two steps one is collecting and analysing data of previous history of energy consumption and another step is to identify optimization of equipment and also setting points and flow rates to improve energy efficiency. Energy management helps to Reduce costs as energy represents 25% of all operating costs, so reducing energy consumption helps to reduce operating. Decreasing usage of energy helps to reduce carbon emissions as in order to obtain sustainability environmental factors play a crucial role. Usage of Natural fuels increase emission of carbon dioxide and usage of Air conditioners increase emission of greenhouse gasses thus increasing energy efficiency helps to reduce pollution. More energy consumption resulted in a high risk of increasing cost of production thus energy management helps to reduce such uncertain risks. World is currently facing increasing demands for energy. According to total energy consumption, it is expected to increase by 48% in 2040. EMS or Employing Energy Management System aimed toward saving energy sources by reducing cost of energy consumption by 29%. It includes Facility Management that reduces consumption of energy costs without reducing quality of work. Energy management in logistics and transportation helps to choose the right means of transport according to road performance that helps to optimize usage of Fuel. Choosing a fuel-efficient vehicle helps to reduce energy costs for transportation.

Efficiency examples

Energy efficiency examples including choosing the right location may help to reduce cost of Air conditioners and heather thus also reducing extraction of CFC. thus, using less energy for cooling and heating for maintenance of temperature. Another example of Energy efficiency includes using Sunlight instead of LED lights to reduce the amount of energy required and also helps to use 70% to 80% less electricity. A major amount of energy in industries is used by transportation; it releases huge amounts of Carbon-di-oxide. Designing and featuring vehicles to improve fuel economy and provide transportation with more efficient vehicles. Energy efficiency of vehicles is usually denoted as “fuel economy” which expresses how many miles a vehicle travels with one gallon of gasoline. Redesigning vehicles with less weight helps to reduce the use of fuel. For example, Hybrid cars have automatic start and stop engines that help to save fuels from wastage. Improving energy efficiency also requires usage of Diesel instead of gasoline or petrol and using Internal combustion engines that convert diesel and gasoline energies into Kinetic Energy. Smart thermostats with wi-fi enabled devices control heating and cooling that helps to reduce energy bills. “Computer power Management” helps to automatically power off when not in use. 

Conclusion 

Increasing energy demands is a great issue worldwide. According to an analysis of current energy consumption, it is expected to double energy requirements in 20 years. That needs management of energy as natural fuels are limited which leads to an increase in price. As 15% of Carbon-dioxide is generated by Transport and vehicles it is important to increase efficiency of transports and using fuel-efficient vehicles helps to reduce population. Increasing energy efficiency is concluded as a common solution for all above mentioned global challenges.
