What Are the Pros and Cons to Solar Energy

!±8± What Are the Pros and Cons to Solar Energy

Using the power of the sun to power our lifestyles, on paper looks like a natural fit. As with all things in life there are two sides to any argument and Solar Power is no different, so hopefully in this article I will answer what are the pro's and con's to using solar energy in today's world

The Pro's to using Solar Energy

1. It is a cheaper way to generate energy, than the normal means of energy generation. The suns power is free, and is a natural resource, using it means that you are not burning any fossil fuels that can ruin the earth's atmosphere. It truly is an environmentally friendly alternative.

2. The suns power is free, most of the cost involved is in the initial investment that is required in setting up the solar powered system.

3. If you do use solar power, you can expect to have no electricity bill, a very small one, or you may actually end up earning money, by supplying your energy back into the electricity system if you live in the right area.

4. No fuel to burn so would be good to the atmosphere. Also if the fuel prices rise and there is a shortage, you will be OK, because you are getting your power from the sun for free.

5. If there was a power outage in your area, you wouldn't be affected, as you would still be getting your power from your Solar Powered system.

6. It doesn't matter where you are, you could be in a remote area and you can still use the power of the sun. You will find solar power being used in some very remote locations.

7. It's a low maintenance system, you don't have to rewire your house, and if you need more power just add more solar panels.

The Con's of using Solar Energy

1. The initial cost, they are costly to setup and have installed, but this initial cost is probably the only cost you have to worry about. Depending on where you live you may also be able to get grants from the government to setup your system, and is well worth checking on before starting looking at systems.

2. You need to live in an area where you can rely on sufficient sunlight to power your system. A system in Arizona or Texas is going to work better than one in the Seattle area that may only receive, on average, about three hours of sun a day since it's a rainy region.

3. You can only get energy during the day, and an overcast day may also cause difficulties, this can be overcome by using a backup battery, that would store energy generated during the day, and supply you with energy during the night.

Getting your energy from the sun, definitely has more advantages than disadvantages, but I think one main sticking point is the initial cost. As solar power technology advances, and becomes more available the prices should come down.

Geothermal Energy - Tapping The Earth's Underground Energy Treasures

!±8± Geothermal Energy - Tapping The Earth's Underground Energy Treasures

"Some researchers believe that by pumping water down to that trapped heat and then using the hot water to turn turbines as it returns to the surface under very high pressure. We could generate power for decades and even centuries" Australian Geographic Beneath the surface of the earth lies a huge treasure of earth's deposit. It is not gold, silver, precious stones or oil. It is the tremendous store of heat called GEOTHERMAL ENERGY.

The temperatures deep inside the earth are in the order of hundreds and even thousands of degrees Celsius. The amount of heat conducted to the earth's surface from this interim in one year is thought to equal some 100 billions megawatts hours of energy and many times the electrical power used world wide; an astounding amount of energy indeed. Much of this heat is stored in underground layers of molten rock, or magma. Harnessing this treasure, though, is a challenge. However, the earth's heat is indeed a treasure because it is a clean source of energy that offers distinct advantage over oil, coal, natural gas, and nuclear power.

The greater concentration of this heat lies under the earth's crust in a layer called the mantle. The average thickness of the crust ids said to be about 35 kilometers. This is much deeper than the drilling capacity of present technology. These crusts, however, is made up of a good number of plates and is thinner at certain places, especially where the plates meet. The magma at the locations is said to be able to rise closer to the earth's surface and the heat the water trapped in the rock layers. This water is usually only two to three kilometers below the surface of the ground, well within the reach of modern drilling techniques. It can be mined and put to good use.

To mine or tap this heat, heat pumps are connected to loops of piping buried in the grounds. The energy is thus gathered and can be used to heat homes in the wintertime or perform other useful works. Usually, water boils at 100 degrees Celsius. However, pressures are much higher underground, and water remains liquid at higher temperatures. The boiling point of water remains increases to about 230, 315, and 600 degrees Celsius at the depth of 300 1525, and 300 meters respectively. During the drilling process, where the drilling taps into water that is above 175 degrees, the water can be used to drive electrical generators.

A lot have been said or have to be said about geothermal energy and its impact on environment. One striking thing about it is the fact that countries that develop power from it reduce their dependence on oil. Take for example, every ten megawatts of electricity generated for a year represents a savings of 140, 000 barrels of crude oil per annum. Equally, geothermal resources are immense, and the dangers of depletion are much less than it is with many other energy sources. Pollution problems are greatly reduced. In addition, geothermal energy production costs are very much at a low side compared with those of many other energy forms.

In spite of all these positive notes, there are some environment concerns. Geothermal steams usually contain hydrogen sulfides, a toxic. This is quite a lethal toxic when much in high quantity and equally a nuisance in low quantities because of its uncomfortable sulfurous smells. However, unlike the other energy sources such as fossil fuels in particular, treatment processes for removing it are effective and more efficient than emission control systems at fossil -fuel power plants. Even at that, particulates in the effluent may contain small amounts of arsenic or other toxic substances. Happily, when these particulates are collected and reinjected into the ground, the danger is kept to a minimum. Another negative side ids the possibility of contamination of underground water supplies, this though can result only when and if the geothermal wells have not been sealed to great depth with steel casings and cement.

Above all, one is quick to note that the sitting of most geothermal power plants is only noticeable by the steams vented from the power plant. With careful management, geothermal power can co-exist with people, animals, plants, and the environment.

Most geothermal power plants are installed using only high- temperature steam for power generators. However, efforts are in top gear to extract energy from fluids that are less than 200 degrees Celsius. As a result, binary -cycle technology has been developed. This uses tapped hot fluids to vaporize a secondary fluid, which in turn drives a turbine/generator set.

All countries living in areas of recent volcanic activity or dormant hot springs sources are enjoined to tap into these earth treasures to save our planet earth from the deadly effects of fossil fuels and make the earth a GREEN place to live in.

www.imdb.me/livefearless Let's face it, I, Sam Botta, cry at movies. It's what happens when you are reared knowing that you are loved by family. I wish this for you. It's not too late. I'm kind of a screenplay junkie, since every work, every mark on the page, every symbol, every expression... has meaning, intentionally there, thought through and alive. Sure it's an amazing art masterpiece that requires a song's worth of listing at the end of the movie after all. Nope, I'm not going to tell you to bring the kiddos to see "The Change-Up" but you should see it. Some know that I've published novels that "ain't" in my name because of the advice I give to help folks I care about. Each novel, lovingly written to help them find what I've been taught that can give the effect of them leading happier, more fulfilling, constantly evolving lives that affect, in positive ways, the course of human events. Novels? Yes. The bulk can be written in less than a week with focused, inspired moments that come when you finally are able to completely disappear for a few hours from the mediocre expectations from those in your world that live the same habits, yet slightly remixed, each day.

Liquid Petroleum LP Gas 1960

!±8± Liquid Petroleum LP Gas 1960

Liquefied Petroleum Gas (LPG), also known as propane, is a nonrenewable gaseous fossil fuel, which turns to liquid under moderate pressure. LPG, a by-product of natural gas processing and oil refining, includes various mixtures of hydrocarbons. The type of LPG used as a motor vehicle fuel is a liquid mixture containing at least 90 percent propane, 2.5 percent butane and higher hydrocarbons, and the balance is ethane and propylene. The mixture is commonly called "propane" among general consumers, but motor vehicle operators using the fuel refer to it as LPG. In 1910, under the direction of Dr. Walter Snelling, the US Bureau of Mines investigated gasoline to see why it evaporated so fast and discovered that the evaporating gases were propane, butane, and other light hydrocarbons. Dr. Snelling built a still that could separate the gasoline into its liquid and gaseous components and sold his propane patent to Frank Phillips, the founder of Phillips Petroleum Company. By 1912, propane gas was cooking food in the home. The first car powered by propane ran in 1913. By 1915 people were using propane in torches to cut through metal. LPG has been used as a transportation fuel, mainly in heavy trucks and forklift vehicles, around the world for more than 60 years. On December 28th , 1984, a preventable tragedy in the giant gas-works on the outskirts of Mexico City left 500 dead and public facilities crammed with injured people. The LPG (liquefied petroleum gas) was stored in massive ...
