As a homeowner, you may be using renewable energy sources. Let’s look at a few of these important, powerful sources.

If you use solar powered lights to brighten your walkway, a solar cover on your swimming pool or hang your clothes out to dry, you are already making use of the sun’s renewable energy. There are many other renewable energy home options you can take advantage of, and by doing so, help preserve our environment.

The most practical of renewable energy options for the home consist of space heating and domestic hot water. This is over 50% of a household’s energy usage. In using renewable energy we can experience cost saving benefits.

Perhaps the best way to take advantage of renewable energy home options is when designing a new house. A southern wall taking advantage of an appropriate amount of windows can take full use of the low sun in the winter. Adding a roof overhang over these windows allow the higher summer sun to be blocked. Also, on a cool day you can open your windows to let a breeze cool off the house and make use of wind energy. You have achieved adding heat in the winter and coolness in the summer, thereby lowering your heating and cooling costs naturally. This is called passive solar heating since it is integrated with no extra costs. You can also do day lighting by taking full advantage of the sunlight during the day to take care of your daytime lighting needs.

Wood stoves can also be advantageous, if using only dead wood, diseased wood or small pellets made from wood chips, crop waste and other organic material for burning. This is a renewable source of heat through the use of space heating. Modern wood burning stoves are highly efficient, making it a more practical option.

A homeowner can also utilize active solar heating. A solar water heater can use renewable solar energy to heat water for a house. This would use solar collector panels placed on a roof. Water runs through pipes under these panels and is heated by the sun. The water travels to a water tank in your home for your use. Electricity can also be produced for a home using the photovoltaic technology. This runs on the same idea as a solar calculator. Solar electricity is ideal for rural homes where it would be difficult to run an electric line to.

Geothermal heat pumps use the heat from the Earth to move heat from one area to another. This system uses a series of underground pipes to move a heat exchange fluid. The heat pump moves this fluid, heated from the earth and transfers it to buildings for use. Initial installation costs are much the same as traditional heating systems, but operational costs are lower.

If you live in a windy part of the country and have quite a bit of land, wind can power a wind turbine to produce electricity for your household. But your location must be ideal to catch wind and you must be able to capture a certain amount for this to work.

These are some home options for renewable energy sources. By trying to utilize some of them we are preparing for our future by using clean energy that does not affect air quality or harm the environment.

Solar energy is one form of energy that is abundant all over the world today. It is also a source of energy that is least harnessed in the world and has some of the best potential. Benefits of solar energy and its move of implementation is examined below.

The simplest transfer of energy we use today is solar energy. Solar energy can be used to warm our pools or to dry our clothes.

The sun is a very powerful star. It supplies us with energy by means of a process known as nuclear fusion. It also sustains the life on our planet. Solar energy otherwise known as the energy from the sun has existed since time immemorial and even the prehistoric men used the power of the sun in order to start fires.

The sun is a valuable and essential resource which radiates enough energy on the U. S in one day to meet the needs of the nation for as much as one and a half years. It is a source of energy that is free, clean and renewable and it is an energy source that will play a substantial role in our future.

The use of solar energy seems like the easiest solution to having an eternal energy source. However the harnessing of this energy is where the problem starts from. The rays of the sun shine over the entire world and not in a single spot. It may take only 8 minutes for the rays of the sun to reach the earth but trying to catch these rays over a wide area can be a very tricky thing to do. Energy available given place will vary according to a number of different factors which include cloud cover and weather conditions.

The use of solar energy in the United States started in the 1890′s when solar water heaters were used. Solar water heating makes use of a storage collector and a storage tank. Flat plate solar collectors are kept of roofs and pipes that carry water are then pumped through these collectors. These tubes are also painted black because this way they tend to get hotter quicker, a storage tank will then hold the hot liquid and this will help with central heating and cutting down on fuel costs. Solar heaters were popular when natural gas was rather expensive and burning wood and coals was a rather bothersome task. The popularity of solar heaters reduced when abundant natural gas and oil deposits were discovered. These fuels are now returning to replace the depleting fossil fuels that had taken their place.

Solar energy is either in the form of heat or light energy. The technology of the photovoltaic converts the energy of the sun into electric currents with the use of solar cells. Electric currents are then used immediately or stored for future use. PV cells also consist of pieces of silicon which are placed under a piece of glass. These pieces have both a positive and negative charge. Certain examples of this are the solar powered calculators that are used almost everywhere these days. Much more complicated examples would be the use of solar panels on rooftops. This usually consists of thin film solar cells used as rooftop shingles, roof tiles or even glazing for sky lights. These solar cells only generate one sixth of the solar energy into power. Bigger arrays are then needed which usually means more costs.

Solar thermal plants make use of the power of the sun in order to heat fluid. This in turn is transferred to steam that is quite similar to what occurs in plants that burn fossil fuel. The steam can then be transformed into mechanical energy in a turbine as well as electrical energy in a generator. The bad thing about solar plants is that they are unable to produce energy on days that are cloudy.
