The Journey to Energy Freedom

Most people reading this will spend a good proportion of their income on energy – lighting and heating your house or apartment, running appliances, fueling your car, and other things. What if you could cut these coats to almost zero and spend this increasing pile of money on, well.. anything else? Technology is at a point where anyone can save significant amounts of money and energy in their lives. The Energy Mohawk is a quest to reduce the amount of money we spend on energy to practically zero and show the simple steps on how to do it. Imagine a life where you spent your money and time on what you actually want to spend it on, rather than working to spend needless money on petrol, gas, light and heat.

We will understand energy across all its forms and use this super-knowledge to be free from energy bills, to spend money on increasingly run-away savings allowing us to spend more money of things which reduce energy costs further. We will no longer worry about oil and gas price increases, or how middle east geo-politics will affect the cost of our commute to work – we can spend that time thinking or doing what we actually want to do. Finally, we can have a lot of fun understanding how things work and getting away from needing to pay other people to do relatively simple things that we can just do ourselves. So here we go. We have the power to free ourselves from the treadmill, let’s do that.

This is our plan, it might take some time, but the first few steps will pay for themselves within a few months:

  1. Put in an energy monitor so we can see what’s consuming and costing us what, and how much we’re saving with these updates.
  2. Change all light bulbs to LEDs
  3. Put in radiator heat reflectors to stop sending half of our heating out of the house
  4. Insulate your attic better!
  5. Install a wood burning stove with back boiler
  6. Replace petrol/diesel car with an Electric Car
  7. Retrofit Dual flush, low water toilet cysterns
  8. Install Double Glazed Windows
  9. Rain water recycling into cisterns
  10. Solar PV Panels to reduce energy bills
  11. Battery system for Solar PV Panels to completely remove energy bills forever
  12. Air source heat pump – magical “free” energy!
  13. Energy inverter with battery / solar array / EV intake ability
  14. Solar panels for hot water
  15. Selling energy to the grid. The final frontier – actually making money from energy and beyond.
  16. Retirement on energy income, invested energy cost savings and super-low living costs.

Step 1: Understand how much energy you consume in your life. he journey in reducing your energy costs to zero starts here. You can’t reduce what you can’t measure. This step alone has been shown to reduce the buyer’s energy consumption by an average of 5-15%. Given the average energy bill is about €850 ($1000) per year, that means your €40 ($50) investment in an energy monitor will save you €127.50 ($150) per year, every year for the rest of your life. If you’re 30 now and you plan to live until you’re 90, that’s €127.50 * 60 years = €7,650 ($9000). Not bad for a $50 investment. And we’re only just getting started!

I’ll take a guess and say that you like in a house or apartment (to tent dwellers, I apologise). Get onto Ebay, Amazon or somewhere else (OWL Monitors are the most popular available) and buy yourself an electricity monitor that will tell you exactly what your home is currently consuming and how much that is costing you in real time:

The Current electricity consumption of your home.

The display unit communicates with the measurement unit, which will clamp around the wire coming into your house or apartment:

Clipping the sensor onto the cable into your home is easy.

Clipping the sensor onto the cable into your home is easy.

Many monitors will not only show you what you’re using now, but will give information on usage in the past. This is particularly useful for figuring out what appliances are consuming what, and when. If you have a tariff which changes with the time of day, or in the future when we all move to a real time electricity price, this information will be very valuable indeed:

Fancy charts showing what was using how much, and when.

Fancy charts showing what was using how much, and when.

So that was easy! Now we know what we’re consuming and paying for. It’s quite easy to see which appliance, light rig, etc is consuming what and how much it is costing. Now we have the information we need to move forward and start saving money.


The journey begins.


What Energy Investment Should I Make Next?

    Hello Mr Mohawk,

    Kudos on setting up this website.
    I like your energy saving plan above. I’ve done steps 1, 4 and 14 with 2 being a mix of LED and CFL at the moment.
    Interestingly, while the electricity consumption of my household declined from 3,500kWh in 2012 to 2,800kWh in 2014 (approx), my electricity cost in 2014 was actually slightly higher! I would expect electricity prices to rise over time generally so I target usage rather than cost. 2015 I forecast at 2,500kWh and at a lower cost as prices have come down a bit.
    Also, I credit most of the saving to lighting – it’s difficult to think of anything else significant I’ve changed. Using all LEDs would of course earn me further usage reductions.
    My gas usage declined from 12,000kWh in 2012 to 10,000kWh in 2014 due to solar panels and heating controls, however the run rate for 2015 is pointing back at the 2012 number, perhaps due to the cold spring or undiscipined tenants.

    I look forward to future posts, you have inspired me to do an energy audit of my house at some point to try arrive at a breakdown of my usage into different appliances/devices. Unfortunately the energy monitor I have is a bit too basic to help much with that.
