Our World’s Water Resources Are in Crisis. Here’s What You Can Do About It
To say that our world’s water resources are in crisis is putting it mildly. The limited supply of freshwater for drinking, cooking, bathing, and sustaining life is becoming one of the scarcest resources.
While almost 70% of the earth is made up of water, clean water makes up only a tiny fraction of all water on the planet.
Let’s put this in perspective for you:
Out of the 70% of the water that is covering the earth surface, only 3% is considered freshwater. Furthermore, roughly 2.6% of this freshwater is unavailable for people.
Why is this so?
2.6% out of the 3% that is freshwater, is either trapped in polar ice caps/glaciers, stored in the atmosphere/soil, is highly polluted or is too far underneath the earth’s surface to be extracted.
That is why many parts of the world (including parts of America) are greatly suffering from a clean water shortage.
Think about it: with all the severe droughts happening in the world, not to mention our continually growing population, it only makes sense that competition for freshwater is on the rise.
According to the United Nations, water use has gone up more than twice the rate of our world’s population increases in the last century. By 2025, an estimated 1.8 billion people will live in areas suffering by water scarcity.
What are the main causes of water scarcity?
Water scarcity is a silly concept to many and a stark reality for others. If you find yourself being skeptical about water scarcity, here are some facts that will make you reconsider the effects of water scarcity:
Oil spillage and fecal matter contaminate oceans, making the water unfit for human consumption.
Overuse or wasted water sadly end up lost to the ground. Wasted water happens every day, instances like leaving your taps running while multitasking or doing other things contribute to wasted water.
When drought occurs, there is usually no rain for a long time. As a result, people do not have adequate water for domestic and industrial use.
Destruction of Water Catchment
Water catchment areas such as forests are being destroyed through deforestation to pave the way for human settlement.
Now that we know that our water supply is not an infinite resource, the challenge we now face is how to conserve the water we have efficiently:
Tankless Water Heaters
As discussions of water conservation rise, the cost of water is also on the rise.
Heating water is the second-highest energy expense in the home, with nearly 20% of average utility bills spent on your water heating system.
Here’s what uses the most water in your home:
- Every time you wash a load of clothing in the washing machine, you consume 7 gallons of water.
- You consume roughly 10 gallons of water for one shower.
- Dishwashers average six gallons per load.
- Two gallons per minute are used when you have the hot water running from a kitchen faucet.
- The bathroom faucet averages roughly ½ gallon of water per minute
This is a lot of (wasted) water.
For this reason, many people are making the switch from a traditional hot water tank to the point of use or on-demand electric tankless water heater.
Switching to a tankless water heater will not only save you significant amounts of money in the long run, but it will also conserve our limited water supply.

Electric Tankless Water Heater Vs Tank
A traditional water heater can last anywhere from 8 to 10 years, whereas a tankless water heater has an average lifespan of about 25-30 years. They also don’t require the regular servicing that the conventional water heater does as there is no “tank” to maintain daily.
With a tankless water heater, you have hot water on demand whenever you need it. When you turn the faucet or the shower on, there is no waiting period for the water to warm up before you start using it.
In contrast, the conventional water heater may take several minutes to heat up once the water starts running, which not only wastes precious water, but it also increases your bills and water usage.
Another thing to consider is that with a conventional water heater, your hot water supply is usually limited to the number of gallons that the tank will hold. That means, once the hot water has been used or “runs out,” it may take several minutes for another tank of water to be heated.
