Many people take for granted that they will get water when they turn on the tap. But did you ever stop to wonder where it comes from and how it gets to you?

Water is one of the Earths most abundant natural resources, but the total amount of water available is fixed. Earth has the same amount of water today as it did when life first emerged on the planet. That’s because our water is in a continuous process of use and reuse. In fact, the water we drink today was the same water the dinosaurs drank. You could actually be sharing a drink with Julius Caesar, Cleopatra or even George Washington!

Most of the worlds water supply is in the form of salt water stored in the oceans. Since converting salt water to fresh water for drinking is generally expensive, it is rare to find a city that relies on salt water as its water source.

Only three percent of the worlds water supply is fresh water, and two-thirds of that water is frozen, in the form of polar ice caps, glaciers and icebergs. Thus, only one percent of the overall supply is fresh water that can be found as either surface or groundwater and used for human consumption. You’ll find surface water in lakes, rivers, ponds and streams, while groundwater is underneath your feet in underground aquifiers.

Groundwater systems are more numerous, but serve smaller populations, while surface water systems serve larger groups. Others receive their water supply from private wells that also tap groundwater sources.

As the worlds population continues to increase, so does the demand for water; however, the worlds water supply does not increase. What there is, is unevenly distributed through precipitation because of varying conditions such as climate and water consumption by plants and animals. So there is not always enough water in places where it is needed. And due to growing populations and industry, the total amount of clean water available is constantly diminishing.

Those of us who reside in developed countries should count ourselves among the fortunate, in terms of water supply. Relatively clean water is a constant in our lives, readily available whenever we need it. However, even developed countries suffer from water woes and contamination issues related to aging infrastructure, treatment breakdowns, human error and geological influences.

In underdeveloped countries, the water crisis tops the list of issues to be addressed. More than 1.5 billion people around the world lack a safe and reliable supply of drinking water, and water-related diseases are the leading cause of deaths across the globe.

While there may be a plentiful supply of water in developed countries, there are still many issues with the quality of the water that is supplied to homes. This could be due to hardness minerals such as calcium and magnesium that can block pipes and cause hard water stains. To remove hard water stains from fixtures and fittings around the home takes a small amount of knowledge about its properties. In particular, knowing that a weak acid will remove them will go a long way to getting rid of them as the acid dissolves away such stains with ease.

These acid solutions can often be made up using simple household ingredients from around the home. There are really easy ways to remove even the most stubborn limescale and hard water stains without any expensive products in 30 minutes using a simple step by step proven method, that will make your fixtures and fittings shine like new!

When people think or energy sources, they mostly think of coal, natural gas and oil, these fuels have been the source of energy for a number of years. One problem however is that they are limited in supply and availability.

Estimates have shown that the currently available sources will only meet our current energy demands for about 50 to 70 years or so. In order to find alternative sources of energy the world has decided to pursue renewable energy sources. However even renewable energy sources have their advantages and disadvantages too.

The available renewable energy sources that we have include solar, hydro, wind, geothermal, ocean and biomass. The most common of these advantages is that they are clean energy sources and do not pollute the air. They also do not contribute to global warming or greenhouse effects. Because the sources of such energy are natural the cost of operations are substantially reduced and they require less maintenance on their plants. One common disadvantage is that it is impossible to produce large quantities of electricity than can be done with fossil fuels. Because they are new technologies the costs of initiating them is also high.

Solar energy utilizes the energy from the sun. It has its advantages because these systems can easily fit into existing buildings and do not affect land use. Since the area that these collectors rest in is quite large, a lot more materials are needed. Solar radiation is also controlled by geography too. It is also limited to the daytime as well as non-cloudy days.

Wind energy makes use of the power of the wind in order to create electricity. Though it produces the most jobs it is reliant on strong winds too. Wind turbines tend to be large and though the areas under them can be used for farming, most people think of them as unattractive looking. These turbines are also very noisy to operate and they threaten the population of wild birds too.

Hydroelectric energy makes use of water in order to produce power. It is the most reliable of all energy sources that are renewable. Its disadvantages are that it affects the ecology and causes downstream problems. Decay of vegetation on the riverbed can also cause a buildup of methane which contributes to the greenhouse effects. Dams may also cause an alteration of the natural river flow and affect wildlife in the area as well. Water which is colder and which is lacking in oxygen tends to be released into the water this kills the fish, sudden release of water like this may also result in flooding.

Geothermal energy makes use of the steam from the Earth’s ground in order to generate power. It uses a smaller land area that other types of power plants. They can literally run continuously throughout the year. The disadvantages tend to be that these plants are site specific and it can bring up toxic chemicals and heat from the earth when it tries to obtain the steam. Drilling such geothermal reservoirs can also cost a lot.

Biomass electricity is made from the energies of wood, agricultural and municipal waste. It tends to help save on landfill waste but the transportation is also expensive and tends to affect the diversity of the land. Other than this the process is quite complex and should be much simpler.

Ocean energy has proven to be a clean and abundant energy form. It tends to be expensive and in order to access this energy, you need at least a 40 degree Fahrenheit difference in water temperature throughout the year. Other than this, the construction and putting in place of pipes may damage the ecosystem.
