Renewable energy is energy that is derived from natural resources which can be replenished naturally. Renewable energy sources are sunlight, rain, wind, geothermal heat, and tides to name a few. Non-renewable resources are not naturally replenish-able, and although there may be currently be an abundance of them, once those supplies are depleted, they are gone forever. Examples of non-renewable energy sources are fossil fuels and nuclear fuels.

There has been an increasing focus on the development and reliance on renewable energy resources for many reasons. There is a fear that we could one day run out of natural resources, such as fossil fuels, thus we will be required to find an alternative form of energy. In addition, renewable energy sources are more environmentally friendly, causing no emissions, which lowers the impact on global warming.

While there are many different types of renewable energy sources, solar energy is one of the most studied and developed. Solar energy is also considered to be one of the most important types of renewable energy. Not only is the sun a large contributor to our everyday energy needs, such as warming the Earth’s surface temperature to maintain life, but according to scientific findings, the sun should be able to provide solar power for at least 5 billion years.

If a building or house is properly designed with the correct equipment, it can be both warmed and lit by the sun, almost eliminating the need to use heating systems and artificial lights. Solar power can also be used to heat water for bathing and for washing.

No matter where you live in the world, solar energy can be used to generate heat and light. While the cloudy atmosphere of Great Britain may not be able to generate as much solar power as Mexico, the sun’s energy is still detectable and usable. In places such as California, Florida, and Mexico, solar energy can be used to run machinery, maintain large buildings, and supply energy to entire blocks of houses.

Capturing solar energy is a sophisticated process, which can increase the price for purchase. In addition, installation on roofs of buildings can be quite complicated and a time consuming process. However, the money saved on utility bills will far outweigh the costs of purchase and installation.

As solar power and renewable energy continues to grow and develop, the costs will hopefully reduce so that more companies and individuals are able to take advantage of the savings while helping the environment.

Aquariums have the power to transport those who may never have the opportunity to see the incredible beauty of life under the sea, to a place of wonder and beauty. Therefore, a well-kept tank which is filled with as much of the nature surroundings and species of a reef as possible, can permit a stunning trip into a world of incredible diversity, color, shape, and variety. A good reef aquarium is indeed something to be valued and sought after. Live rocks can be a wonderful addition to the underwater ecosystem which you create.

A live rock is simply a rock. However, it is what lives on the rock that makes it a living rock. There are both macro-organisms and micro-organisms that digest the waste of fish and other animals which vital to the ecosystem and therefore can be a great addition to the aquarium. However, it is not just about taking a rock and putting in the aquarium and hoping it works. There is a process that needs to be understood and followed to make sure that the benefits for the aquarium and the live rock are the best they can be.

The process for curing a live rock is very simple but this important step must be done carefully. Otherwise, there could be a rise in the level of ammonia in the tank that would hurt the fish or possibly kill them. The first step in curing the rock is to choose a container which will be large enough to hold the rock you wish to cure.

Then, fill the container with saltwater. Next, place a heater and water pump in the 'tank' to provide good temperature and circulation control. As the water reaches the proper temperature, take the heater out and as well as half of the water. Then take the rock and clean it thoroughly being careful to remove as much of the loose organisms and debris as possible by stirring the rock in saltwater in a separate bucket.

Take the now clean rock and put it in the water already prepared. Install the heater and pump once more and let nature take its course. The whole process is finished when the ammonia scent is no longer present and the ammonia level in the water is absolutely zero.

At this juncture, it is now safe to put the rock into the aquarium and let Nature do her work with a perfectly natural filtering system thanks to a living rock.
