When it comes to the advantages of making use of solar and wind power you're going to see that 2 of the main reasons that men and women should do this is to save the planet and to save money. Individuals can wind up saving an enormous amount of cash by utilizing these alternative energy sources as they are able to help people eliminate their power bill. Due to the costs involved in switching your house over to run on solar and wind power, is among the primary reasons this isn't something that is practiced more widely. Even though converting your house to run on solar and wind can be expensive it's significantly less expensive than many men and women believe.

In order for the major electrical companies to supply electricity to all of the homes, they ought to use an enormous amount of our natural resources. Individuals can in fact decrease the amount of electricity that the big organizations need to create simply by switching over to solar and wind power, and as a result this would reduce pollution. You can save cash, our resources and in addition decrease the pollution that's created each day by simply making use of these clean energy supplies. These reasons alone should be more than enough reason for any person to think about making use of these alternative energy sources.

Solar Panels

In general, solar energy can be described as the energy that is received from the sunlight and converted by a mechanical source for home use. It's cheaper and reliable for operations since the sun is readily available. On the other hand, solar panels are the mechanically built materials whose main purpose is to convert solar energy to electrical energy. They are built from an element called silicon. It is the core duty of the silicon element to covert the solar energy to electricity. The solar power can either be directly or indirectly gotten from the sunlight. When it's cloudy the intensity of the solar power delivered perfectly, the photovoltaic solar materials deliver sun rays into electricity and the solar thermal receiver changes the solar power into heat solvents, such as oil and water. This type of power is used in, iPod chargers, charge batteries water heaters, cell phone chargers and spacecrafts.

How do solar panels work? They practically work on the photovoltaic invention. Its name is derived from the technology used, which is also known as PV, which is made from silicon element. They are basically semiconductors made from sand built into large computer chips. When sun rays falls on the PV materials, the PN junction in it with its metal conductor helps produce electricity. At this juncture, the PN junction is the positive and negative charges that assist to produce electric current. Solar energy is available in different systems, grid connection, inverters and power storage. In a different system, the PV takes up large space up the roof to produce more energy. It can also be built on land space and produce up to 5-9 Megawatts per hour. They can also be useful in street lighting.

Why We Shouldn't Use Fossil Fuels

Fossil Fuels

Consumers are familiar and comfortable with conventional power sources. Power generated by fossil fuels such as coal, natural gas, or petroleum (oil) is widely used across the world and many countries rely on these finite resources as the primary source of power production. According to the latest report by the U.S. Energy Information Administration (2011a), fossil fuels are expected to continue supplying much of the energy used worldwide, with petroleum based fuels remaining the largest source of energy.

However, there are significant problems with relying on this type of energy. Firstly, fossil fuels are not considered a renewable energy. The formation of coal, natural gas and oil takes millions to billions of years; consequently these resources will be consumed well before they are renewed. Experts have suggested that the world is currently at the peak of oil production, with only another forty years of oil reserves available and sixty five years of gas remaining. With population growth continuing to rise and the nature of economic growth and consumption, undoubtedly these fossil fuels will become very scarce and eventually unavailable.

It is reasonable to expect that as these resources become further reduced, the cost of power will increase and it will become less affordable for many people. This is a scary prospect, especially for future generations.

Whilst there are very legitimate concerns about the future availability of fossil fuels, another problem is the environment impacts of using fossil fuels for our principle energy source. Fossil fueled power stations are major emitters of carbon dioxide (CO2), a greenhouse gas considered one of the major contributors to global warming within the last century. For example, the burning of brown coal emits three times as much CO2 as natural gas, and black coal emits twice as much CO2 per unit of electric energy generated. Unless new technology can be developed to make energy production 'greener', regulations to reduce CO2 emission will certainly impact the consumer, whether this is by higher prices due to carbon taxes or a limitation to the amount of energy available.

The impact of burning fossil fuels on human health is also a major concern. For example, exposure to particulates released from coal power plants has been proven to increase death through respiratory and cardiac problems (Grahame and Schlesinger, 2007). These particulates irritate small airways in the lungs, which can lead to increased problems with asthma, chronic bronchitis, airway obstruction, and gas exchange (Nel, 2005). Uranium, thorium and other naturally occurring radioactive isotopes are also found in low levels within coal. Whilst they are in low concentrations, there is enough coal being burnt that there is a significant amount of these substances being released, causing radioactive contamination of the environment. Other damaging side effects of burning coal are the contamination of waterways. Research has shown that the coal ash produced by coal-fired power plants dumped at sites across America has lead to the contamination of ground water with toxic element, including dangerous poisons such as arsenic and lead (Schoof, 2010).
