Energy drives everything in today’s world. Our future world depends a lot on energy. We generate and consume more energy than before as a global community, and the demand for energy is increasing exponentially. While we have been able to increase energy production to meet requirements, there are physical, geographical, and economic constraints on how much can be produced.
On the other side, due to the use of fossil fuels for the generation of electricity, greenhouse gasses are getting accumulated in the atmosphere, resulting in climatic consequences.
It is very necessary to deal with the ever-increasing demand for energy and the difficulties that arise due to its usage. There comes the term energy conservation. It is the term used nowadays by most academic people around the world. Many discussions around energy conservation are going through social media, news, etc.
In the following sections, you will know about energy conservation, the need to conserve energy, and the most important methods used to conserve energy.
What is energy conservation?
Energy conservation is the effort taken to reduce the consumption of energy by using less energy or producing it. It is achieved either by using it more efficiently or by reducing its consumption in physical terms.
Energy conservation can be achieved by using energy-efficient appliances, which use less energy. This can be done by producing more energy-efficient products and supplying them to energy consumers. Conserving energy will help to create a sustainable environment. Efficient usage of energy prevents unnecessary waste, thereby ensuring its continuous availability.
If the current trend of increasing energy continues, we should be ready to face the negative consequences of climate change such as an increase in temperatures, more acid rain, and more frequent extreme weather changes.
Hence, energy conservation is not just a topic to discuss and move on. It is an effort or a practice that every individual should follow energy-efficient measures in order to ensure a sustainable world.
How energy conservation is related to energy efficiency?
Energy efficiency and energy conservation are related terms, but they both have distinct definitions. Energy conservation is the practice of using less energy. On the other hand, Energy efficiency is a method of using technology that uses less energy to perform the same function.
For example, turn off the lights when not in use in the way of conserving energy. But replacing fluorescent light or incandescent light with energy-efficient bulbs is an example of energy efficiency. The implementation of energy-efficient technologies will reduce energy consumption.
What is the need to conserve energy?
In the present days, most of us are very lucky to have electricity at our home. There are only a few people who understand the need to conserve energy and they act on it. But some people around the world do not realize the issues that we face in our environment.
Fossil fuels are used by most countries for generating electric energy and thermal energy. It is a non-renewable energy resource that most types of energy equipment rely on it. If fossil fuels run out, it is not possible to recreate them. For example, we can’t pump oil from the Earth, if it gets empty.
Burning fossil fuels and energy usage will pollute the environment in a number of ways. In order to reduce pollution and to preserve our natural resources, it is essential to conserve energy.
Benefits of energy conservation
Saving energy can help you save money on your energy bills. Energy conservation can help the environment by lowering carbon dioxide emissions and other greenhouse gas emissions and other pollutants. Conserving energy will bring economic and environmental benefits.
Environmentally, saving energy will reduce poisonous gas emissions. Economically, saving energy will save you money on energy costs. Additionally, it also has more health benefits for all the living things on the earth.
The utilization of non-renewable resources impacts our environment. Just Imagine, what happens when fossil fuels such as oil, coal, and natural gas are burnt in power plants? It pollutes the air, water, and land due to the greenhouse gas emissions into the atmosphere.
These activities will cause serious effects to the earth causing global warming. We can observe the effects of global warming through irregular climate change such as melting ice glaciers, rising sea levels, forest fires, etc.
Conserving energy will save all the cities in the coastal areas from disappearing under the water. The quality of air and water can be improved by reducing carbon emissions. The change of climatic conditions can be prevented by effectively following the energy conservation methods.
The fossil fuels, which were abundant once, are getting vanished as the year goes on. Due to this, the cost of drilling and mining fossil fuels is increasing, which reflects back to the consumer’s cost. You can notice the increase in the price of petroleum products in the market.
If the dependence on these fuels is reduced by switching over to renewable energy resources, then the consumers will definitely taste the benefit. If we rely more on renewable energy resources, then fossil fuels will exist for a longer period, which will slow down the price of the fuels.
On the other side, conserving energy will save you money on utility bills. A small change that you take to use your electrical items in an efficient way, would save your electricity bill. Using energy-efficient products at your home and office will save your electricity bills.
As discussed above, the usage of non-renewable energy resources causes the accumulation of poisonous gases such as sulfur oxides, nitrous oxides, etc., in the atmosphere. These gases react with water in the atmosphere to form acid rain.
Acid rain is the rain with acidic components that affects the ecosystem, marine system, and human health conditions. The plants, cereals, fruits, and vegetables get affected by the acid rain resulting in skin irritation, cancer, respiratory issues, and cardiovascular problems in human beings.
Fossil fuels and Energy conservation will reduce the effects of poisonous gases released into the atmosphere. Energy-efficient alternatives will assist the life on earth to sustain without health issues.
Methods of energy conservation
Conserving energy is a very simple and easy task that everyone can practice to save the earth. It should be the habit of every individual to reduce energy usage. There are various methods to save electricity in your home and office. Some methods require investment to implement and some do not need any investments. We have given the top 10 ways to conserve energy.
Use energy-efficient light bulbs
The energy consumption of traditional incandescent light bulbs is pretty high. Also, the heat energy produced from such bulbs is severe and has a short lifetime. Even though fluorescent bulbs (CFLs) consume less energy than incandescent bulbs, all those must be replaced with energy-efficient light bulbs.
LED bulbs are the most energy-efficient bulbs. It consumes only around 20% of electricity consumed by incandescent light bulbs and gives enough brightness. Although the LED bulbs are expensive, they cut off the energy bills and can be used for a longer time.
Use energy-efficient appliances
Not only light bulbs, but it is also better to use energy-efficient appliances in your house. Of the total household energy use, appliances play a vital role. Because every house consists of different appliances such as air conditioners, washing machines, microwave ovens, etc.
Many use the old appliances at home without proper maintenance. The energy consumed by the old appliances will be more. Replacing the old one with the new product is always challenging in terms of its price. Though the investment is high, the energy efficiency will improve and energy costs will get reduced.
When looking to purchase a new product, look for the energy STAR label of the appliances. Buy the product with more star ratings, as this will save energy.
Turn off lights and appliances when not in use
This is one of the simplest methods of energy conservation. You need not go and buy any products to reduce energy consumption. It is just as simple as turning off the lights and appliances when they are not in use.
Whenever you leave the room, turn off the lights and fan. Whenever you leave the hall, turn off the television and other appliances. If you are finished in the bathroom, turn off the appliances. These simple steps will save energy at your home.
Use natural light during daytime
People have the habit of closing all the windows in their homes during the daytime. They would like to sit under the lights. But they are not aware that their action will increase the energy use at home or office.
It is advisable to make most of the sunlight during the day. The drapes or curtains on the windows are to be kept open during the daytime to receive the natural light. In this way, you could avoid unnecessary usage of electrical lights and reduce energy usage at our home.
Defrost your refrigerators regularly
Refrigerators are used in most houses to preserve food and beverages for a longer time. But refrigerators are often not operated efficiently. The first and easiest thing to conserve energy in a refrigerator is that the door should be closed perfectly. If not, the cold air escapes from the appliances and hence requires more energy to cool them.
The frost accumulation on the coils inside of your refrigerator forces it to work harder. If you do not defrost your refrigerator and freezer on a regular basis, the appliance may struggle to maintain cooler temperatures. This frost buildup can waste a lot of energy and cost you a lot of money on your utility bills. Thus regular defrosting should be done to conserve energy.
Clean or replace air filters in air conditioner
Normally, an air conditioner or heater is the biggest energy user in most houses. This appliance is operated during summer and winter. Regular usage of air conditioning systems will result in the deposition of dirt in the air filters.
Improper cleaning of dirty air filters will make the appliance work even harder. If unnoticed, the energy efficiency of the conditioner will become poor. To conserve energy, regularly clean the air filter in the air conditioning system.
Repair any electrical issues
In any home or building, the occurrence of electrical issues such as flickering lights, electric surges, burn-out bulbs, etc is common. But it should be addressed immediately. If you notice any such electrical issue, it should be fixed it right away.
Such fixes will ensure that the electrical equipment is operating with energy efficiency while optimizing energy output.
Take a walk or use bicycles
Technological advancement around the world had led to the rapid growth of the transportation sector. Almost every family owns a vehicle, either a two-wheeler or four-wheeler. The rapid growth had resulted in an increase in energy consumption and the release of poisonous gases into the atmosphere.
In order to conserve energy and save our earth, it is our responsibility to look at alternatives. One of the best alternatives is to travel short distances either by walking or using bicycles. This effort has a number of advantages for both the environment and our health.
Traveling short distances through walking or using bicycles will reduce the consumption of energy resources. Since no emissions are there, our environment will be protected. You could be able to save more money. These energy conservation efforts will also be a good exercise for your body and help in strengthening your immune system.
Switch to renewable energy resources
Non-renewable energy resources are limited and are depleted within a few years. Since these resources have serious effects on the atmosphere, it is the need of the hour to switch to renewable energy resources.
Renewable energy provides significant benefits for our environment, our health, and our economy. The majority of renewable energy sources produce no carbon pollution. You could either install standalone photovoltaic systems, biomass power generation to supply electricity for your home and start conserving energy.
Energy Audit and Energy Management
It is the method of inspection and analysis of energy flow in a building or home or industry to implement energy conservation. Using this method, it is also possible to determine energy wastage.
The objective of the energy audit is to minimize energy costs and reduce energy waste without affecting the process quality. Its outcome is to provide recommendations for improving energy efficiency.
