The Energy Efficiency Definition – Guide
Share the Love of Healthy Living...

Welcome to my 'The Energy Efficiency Definition' post!

First of all, I must congratulate you for taking the time to do your research on this topic of green living. Reducing our overall demand for energy is what we call being energy-efficient. The climate crisis is here and understanding what you can do to become energy efficient is vital. 

As a qualified teacher, I am passionate about education and the impact it can have on bettering our future. It is down to us individuals to do our research and make small changes to the way we live our lives. 

These small changes are easy to make and can have a big impact on our health, the health of our family and our environment. This website is designed for everyday people looking to make these changes. Here you will learn a legitimate way to go green. 

Let me be completely transparent with you, I am not here to pitch or sell anything to you. I am here to reveal and to assist you on your journey of going green! 

What is Energy Efficiency?

We become more energy-efficient once we use less energy, or switch to more efficient energy sources, like renewable energy sources. So becoming energy-efficient means making changes that end in reduced energy usage (and cost)!

For instance, employing a low-energy light will still provide you with light and is more energy-efficient than a high-energy one. Installing solar to power the electricity in your home will provide you with electricity from a sustainable source.

Climate Change

Climate change describes a change within the average conditions — like temperature and rainfall — during a region over an extended period of your time. For instance, 20,000 years ago, much of the US was covered in glaciers. NASA scientists have observed the Earth’s surface warming, and lots of the warmest years on record have happened within the past 20 years. We now have a hotter climate and fewer glaciers.

Global climate change refers to the typical long-term changes over the whole Earth. These include warming temperatures and changes in precipitation, also because of the effects of Earth’s warming, such as:

  • Rising sea levels
  • Shrinking mountain glaciers
  • Ice melting at a faster rate than usual in Greenland, Antarctica and therefore the Arctic
  • Changes in flower and plant blooming times.

Earth’s climate has constantly been changing, even long before human behavior impacted it. However, scientists have observed unusual changes in more recent years. For instance, Earth’s average temperature has been increasing far more quickly than they might expect over the past 150 years.

The Climate Emergency...

Climate crisis is a term describing heating and global climate change, and its devastating consequences. The term has been used to describe the threat of worldwide warming of the earth and to urge aggressive global climate change mitigation.

A BioScience article on January 2020 endorsed by over 11,000 scientists worldwide, stated that the climate crisis has arrived and there is an immense increase in endeavors to conserve our biosphere is required to avoid untold suffering to the planet and humanity.

Does What we Do Matter?

Yes. Human activities create greenhouse gases and this causes the surface of the Earth to warm up. This matters because oceans, land, air, plants, animals, and energy from the Sun all have an impact on each other.

The combined effects of these things give us our global climate. In simple terms, Earth’s climate functions like one big, connected system. Thinking about things as systems means trying to find how every part relates to one another.

NASA collects information about how our planet’s atmosphere, water, and land are changing using Earth-observing satellites. By watching this information, scientists can observe how Earth’s systems work together. This may help us understand how small changes in one place can contribute to greater changes in Earth’s global climate.

Why is Energy Efficiency Important?

If we do not start making changes to the way we produce and use energy, we are in danger of suffering the harmful effects of worldwide climate change, like extreme weather events, rising sea levels and acidification of our oceans.

By identifying ways to be more energy-efficient and source more of our energy from clean, renewable sources, we'll create a more sustainable future for our planet and future generations.

Which Energy Sources are the Simplest for Energy Efficiency?

Choosing renewable sources of energy to power our homes and businesses helps to scale back greenhouse emissions. The great news is that renewable energy sources won't ever run out, we will have access to these clean energy sources for as long as we need! Renewable energy sources include:

  • Wind energy
  • Solar power
  • Hydropower
  • Geothermal energy

Do I have to Make Big Changes? - No!

Becoming energy-efficient is often achieved through small actions that have a big impact. If we all play our part to live in a more energy-efficient way, together we'll make an enormous difference to the longer term of our planet.

Becoming More Energy-Efficient

Being more energy efficient involves making choices that reduce our overall energy consumption. This will range from small changes, like turning appliances off at the wall. If you want to make bigger changes then you can consider installing insulation in your home. There are numerous simple ways to become more energy-efficient and remember - even the littlest of changes can make a difference!

Becoming energy efficient is straightforward. Read these quick tricks and quickly make your home energy efficient!

  • Use eco-friendly light bulbs - swapping your old-fashioned lights is best for the earth and your energy bill.
  • Turn off your electronic devices at the wall - even in standby mode, they will still be draining energy, so always remember to 'turn it off'.
  • Switch off your computer when not in use because a computer left on all day uses nearly 1000 Kilowatts of electricity per annum.
  • Cut back on your long hot showers as heating water is that the second-largest source of household greenhouse emission emissions
  • Switch to Green Power - encourage your family to shop for electricity that's generated by renewable energy sources for a serious efficiency boost.
  • Make sure your fridge is running efficiently - check the seals so cold air can't escape.
  • Fix up your home efficiency - check thermostat settings o ensure you set an inexpensive temperature for different seasons.
  • Buy energy-efficient products - many electrical products now accompany an energy star rating, which makes it easy to pick more efficient options.
  • Choose a different way to commute to work - rideshare, cycle, walk, public transport.

  1. Hi and thanks for this. You are right that the first and most important thing young people can do is to become aware of how their own daily routines and habits are either energy-efficient or inefficient. And then work out where small changes can make the biggest differences. I am curious to know, as a teacher, which areas of behavior in young people have you found to be most amenable to change. Thanks, Andy

    1. Hi Andy, I think that making changes to our behavior is everybody’s responsibility, not just young people. We all live here together and we will have a bigger impact if we all make changes. Also, it is our responsibility to get it right so that we can have a positive influence on our children, as they learn from the behaviors they see in their environment. As a teacher, inspiring change comes from initiating a passion and instigating fun as this is how children best learn. Therefore practical lessons and field trips where children can learn through fun and differentiated communication on topics will provide the best learning opportunities.

      I hope this helps. Thank you for reading.

  2. Great article! I especially liked the tips at the end. I have always felt that “going green” was difficult. Like you had to go out and install solar panels or only every use reusable containers (which I still try to do), but this list really shows how small little everyday things can make an impact and it’s really motivated me to do more!

    Thanks!

  3. Your article is very complete, as always 🙂
    What do you think: I moved into a house last year that had most lights and equipment installed. I am still doubting whether to replace them, and add to the useless waste, or use them until the end of their lifecycle?

    1. Hi, I think it is about carefully choosing which green changes will have the biggest impact on the lowest output. You budget will play a role in this too. To me LED lights are a no brainer so if you don’t have these definitely start here. After that, look to your power source and research the power companies in your local area.

  4. Great post. I’m very conscious of energy and going green. Recycling where possible, using less power, even changing utility providers to those with renewable sources of power as their main/only supply sources.

    All the best!

  5. Good Afternoon Catherine – I wonder what the future will hold for the internet with a lot of talk circulating about energy efficiency at the moment. The amount of power that is required to stream videos and music is probably astronomical – perhaps we will all have to start getting into downloading and playing on our devices instead?

    1. Yes, this is true, although lots of the big companies are countering their non-renewable sources by investing in green projects. Although this is not a solution it is definitely better than what most small companies who are off the radar are doing.

      With regards to personal energy use in the home, a big issue is that we are always connected to our 4G and5G accounts when we are not using them, turning off devices, or disconnecting them will save a lot of energy. Yes, downloading saves an awful lot of power.

  6. Hi EcoCatherine,
    Great post, and thanks for sharing this amazing tricks of making a small change to protecting the planet for us, our family, and future generations.
    I didn’t know that leaving my computer on is consuming so much energy, which is something I have to start turning off, including all my other electronic devices.
    You always deliver and I love coming to your site to educate myself about going green.
    Looking forward to your next post.

    1. I am pleased that you enjoyed reading this. I too spent many years closing the lid of my computer but now turn it off at the end of the day. i was surprised to see how less often I needed to charge it. All the best and thank you!

  7. So true,

    The younger generation for sure needs to be more AWARE of the effects of all of this. You don’t really think much until it hits home, but something like this when that happens will be too late.

    1. I think it really is down to all of us to make changes today. Although we may not have been responsible to the industrial revolution, our daily lives certainty reap the benefits from technological advancements.
