Solar Energy And Water Conservation : Understanding Sustainability

Understanding the Connection

When discussing solar energy, the conversation often revolves around electricity generation and reducing carbon emissions. However, an interesting and often overlooked connection between solar power and water conservation deserves our attention.

This relationship represents one of the most important hidden benefits of switching to solar power. Understanding this relationship can help us make more informed decisions about our energy future.

The Water-Energy Nexus

At the heart of this connection is the link between water and energy. Traditional electricity production relies heavily on water resources - whether it's coal or nuclear, huge amounts of water is required for cooling systems and steam production processes. Conventional power plants can use millions of liters of water per day which is becoming increasingly unsustainable in a world facing the challenge of water scarcity.

On the contrary, the solar PV system uses no water at all to produce electricity. The only water requirement comes from cleaning the panels from time to time. 

Measuring the Impact

These changes and this opportunity have clear and measurable results on water conservation when switching to solar power on a large scale. In aggregate, throughout a typical residential solar system’s lifetime, these direct water savings can represent several hundred thousand litres or in more colourful terms several swimming pools’ worth of water.

Infrastructure Benefits

 In addition to physical water savings, solar energy has many ‘wider water implications’. In this respect, by curtailing the demand on conventional power plants, solar power saves municipal water treatment systems and cooling tower water processing systems reducing pressure on water infrastructure systems.

Environmental Protection

The environmental consequences of the interactions highlighted in this paper are most relevant to watershed protection. Conventional power plants discharge water with a higher or lower than required temperature to natural sources causing thermal pollution to affect aquatic life. However, solar systems erase this impact altogether.

Residential Impact

For residential users, the advantages cannot be indirectly limited to water savings. The beauty and sheer size of solar installations tend to help contribute to a change in attitudes toward resource conservation. In such cases, survey respondents who installed solar panels also practice other strategies to save water hence enhancing compound conservation.

Future Implications

With the climate change factor that is steadily reducing the availability of water globally, the use of solar power in saving water will be of high value. Technological developments are already increasing this relationship rewarding such novelties as self-cleaning PV systems and better solar thermal systems that often cut water demand even more.

In going solar, property owners don’t simply build real estate capable of detaching itself from the national electric grid – they support water conservation the world over as well.

This emerging value of water makes the fact that solar energy is a waterless system a value that will only increase with time, which means investing in solar, is investing in a clean energy source of the future.
