Humanity’s generational hope is to relieve people from harsh physical labor and provide them with more leisure time. Animal power has played a significant role throughout history and has been a leading economic force, with animals making it easier for people to farmland and transport products.
Bioenergy has been used for millennia in addition to animal energy. As energy needs grew, people began to use water and wind energy in addition to wood, culminating in the first industrial revolution in the United Kingdom.
The energy needs were growing every day. How will this affect our future?
How Humanity’s Energy Needs Will Affect Your Future?
Humanity’s energy needs are growing every day as the world gets more industrialized, and it is negatively affecting our future because, at the moment, the world can not produce as much energy as it needs.
The preoccupations of modern civilization are to provide enough food for a growing population, enough raw materials for industrial production, and enough cheap and quality energy.
Lack of food, raw materials, or energy would lead to severe disturbances in the modern economy and society. Lack of power would have catastrophic consequences, as all modern technology would be paralyzed, and manual production would be too modest to provide enough of the goods needed to meet current levels of societal needs.
What is the answer?
So, providing sufficient amounts of energy is one of the key conditions for the survival and development of our civilization.
The best chance for humanity to produce enough energy is to turn to renewable energy.
How does energy affect people’s lives?
Physics defines energy as the body’s ability to do work, so we need the energy to walk, get up, sit, work, study, etc. We get that kind of energy from food and water. Of all the forms of energy, electricity has become an essential part of every human being.
Every day, people use energy for transportation, cooking, heating, cooling, production, and lighting, as well as for entertainment and many other purposes.
However, how we use all of this energy has a significant impact on our environment and lives. As a result, it’s critical to make the best use of it (whether used appliances and technology fall into the category of energy-saving products).
With this in mind, we can distinguish two categories: energy saving and energy efficiency.
Saving energy means everything we do to avoid wasting energy – these are simple steps that everyone can adopt as a way of behaving, from turning off the lights after leaving the room to recycling plastic or aluminum packaging.
On the other hand, energy efficiency is a term that refers to the use of technology that requires less energy – a good example is energy-saving LED bulbs that consume less energy instead of conventional bulbs while giving the same amount of light.
What kind of energy does the world use the most?
Currently, the world covers its energy needs mainly with non-renewable energy sources:
- fossil fuels (coal, oil, and natural gas)
- nuclear fuels (uranium, thorium, etc.)
The two main problems with non-renewable energy sources are:
- To have them in limited quantities
- They are harmful to the environment
As the name suggests, non-renewable energy sources are not renewable, which means they cannot last forever. Energy needs are increasing over time, so non-renewable every would not be able to respond to the demand.
Fossil fuels are very harmful to the environment because during combustion:
- Emit large amounts of carbon dioxide CO2 and other greenhouse gases methane CH4) into the atmosphere, which has led to a global rise in temperature on Earth.
- Emitting large amounts of gases (carbon monoxide, sulfur dioxide, nitrogen oxides), smoke, ash, dust, and other particles pollute the environment.
CO2 emissions from fossil energies will be associated with an increasing number of future public health risks. Nuclear fuels are not dangerous to the atmosphere, but the substances formed during the reaction remain radioactive for years. So, fission creates hazardous radioactive materials that need to be properly stored.
Why is energy important to society?
Can you imagine a day without electricity? No electricity means no internet. Whether you are at work, at home, at school, or at college, the use of electricity is every day. We use it for heating, cooling, cooking, lighting, transportation, and more.
However, energy needs significantly affect our environment and life. Therefore, the importance of this topic is not only in whether we turn off appliances when we do not use them but also in whether they fall into the category of economical, i.e., energy-efficient devices.
Refrigerators, washing machines, boilers, computers, televisions, and trolleybuses run on electricity.
Doctors, accountants, teachers, installers, and trolleybus drivers will not be able to work without electricity. It is because many devices that people need are powered by electricity. Without electricity, the dentist can’t heal the tooth, the trolleybus driver can’t transport passengers, and the installer will not be able to grind the part on the machine.
Modern industrial society definitely cannot exist without electronic devices. And energy needs are constantly growing.
What is the future for our energy needs?
The 21st century brings prominent changes in society, politics, economy, and security. The EU, UK, and the USA want to maintain their economic competitiveness in the long run and are therefore very mindful of all the challenges of the modern world.
Learned from the experience of Japan, which has lost its position as the world’s most prosperous economy due to excessive dependence on fossil fuel imports, these countries have long pursued a clearly defined energy policy to take the lead in the world economy.
By 2050, there are likely to be around ten billion people living on the planet increasing the energy needs. With about one million people moving to urban areas each week, more and more people are likely to live in cities, where they usually spend up to 90 percent of their time indoors. Because everyone wants a comfortable indoor environment, this creates higher energy requirements for air conditioning and heating systems. It can be expensive for households. Heating, cooling, and ventilating our homes is our highest energy consumption, representing up to 16 percent of the total consumption of the average home.
The future of our energy needs is in energy efficiency, suitability, and Zero waste. Those measures are taken to reduce energy consumption and losses. The use of renewable energy sources and improving energy efficiency contribute to:
- reduction of greenhouse gas emissions (primarily CO2 and methane), which contributes to the reduction of global warming;
- reduction of fossil fuel imports;
- creation of new jobs (ecology, energy, economy);
- energy independence, because the dependence on the import of energy raw materials and electricity is decreasing and the energy needs are increasing;
- development of the local industry;
- energy sustainability of the system increases;
- new production programs and services appear;
- opportunities are created for the use of different energy sources;
- more efficient use of own potentials in energy production
Daniel Knapp’s notion of Total Recycling may have been the first to use the term zero waste and the start of a movement. By the end of the decade, the zero-waste concept had gained traction, and Georgia Senator D. James, in collaboration with GRRN, introduced the first zero-waste legislation in the United States by 2020.
