How much energy will I save by using solar hot water?

We have already looked at how much money you can save by installing solar hot water systems, but what about your energy savings? Find out just how much power you can preserve by going this green route, learning from research and experts in the field.

Put things in perspective

Before your jaw drops at just how much energy you can preserve through solar hot water, you should know why these savings matter. The End-use energy intensity in Australia report noted that over the years 1980-2013, final energy consumption in the end use sectors nearly doubled – it grew by 1,853 petajoules, which equals to a 2 per cent growth every year over the last two decades. In direct comparison, 2013 energy usage was 88 per cent more than in 1980.

The report noted that saving energy will cause the following benefits:

  • Lower energy costs for businesses and households
  • Reduce in energy-related greenhouse gas emissions
  • Improved competitiveness
  • Better energy security
  • Fewer investments needed in developing energy resources and infrastructure

This spectrum of perks will go a long way towards helping Australia leave only the most miniscule carbon footprints on our planet.

The CSIRO Home Energy Saving Handbook noted that everyday usage of hot water can account for around a quarter of your total energy consumption. On the other hand, solar hot water can save as much as between half to three-quarters of your hot water energy usage – that’s significant savings not just for the planet, but also your pocket.

This government organisation claims that solar hot water can provide between 50 to 90 per cent of your total hot water needs, depending on how much you use and the weather in your neighbourhood. This means the energy you use up for heating can be minimised to as little as 10 per cent, and in other cases, a positive 40 per cent.

Energy Efficiency and Conservation Authority (EECA)

Across the Tasman in New Zealand, the EECA also advocates for solar hot water energy through its subsidiary organisation Energywise. They draw to attention that although a back-up electric, gas or wood heating source might be needed to compensate for solar, on the whole solar hot water is useful. This is because the sun’s natural energy can provide as much as 75 per cent of your heating needs, meaning the energy consumption of using back-ups is dramatically reduced.

All of these official, reputable bodies are taking the time to advocate for solar hot water. If you’d like to join the movement, call us at Apricus today and start saving energy.
