The Importance of Renewable Energy Resources

Posted by admin on July 31, 2012 in Renewable Energy with 3 Comments


The modern lifestyle depends tremendously on the use and existence of fossil fuels. With levels of these fuels constantly decreasing, we should act now to become less dependant on fossil fuels and more dependent on renewable energy sources.

The decreasing levels of fossil fuels isn’t the only reason why we should begin to use renewable energy. Pollution is becoming a huge problem in many countries around the world, especially the developing world. With carbon emissions at an all time high, air quality can be very low in some areas, this can lead to respiratory diseases and cancer.

The main reason to switch to cleaner energy production methods is the global warming aspect. The more carbon dioxide we pump into the atmosphere, the greater the effect becomes. We can’t just stop using fossil fuels thinking that global warming will go away, but we can slow down and dilute the effects of Global Warming through the wide spread use of renewable energy resources.

There are many natural energy sources out there, but you have to decide which method is best for you, as all of these sources depend on your current environment.

The installation of a solar panel or a wind turbine to boost every homes power supply would be an amazing step forward. Some governments are in the process of supplying solar panels to hundreds of households to test this method of energy saving.

A technology set to be very important in the future is geothermal energy. With geothermal energy, you are able to extract heat from within the earth and transform it either into a hot water system, or if there is plenty of this energy, a geothermal power plant. Huge amounts of money have been flowed into research of this method, especially in recent years, in order to make the current technology more effective.

So there we have the reasons why we should turn to Renewable Energy resources which are more than likely to play a very vital and important role in our future society.

Barack Obama and Global Warming

Posted by admin on July 31, 2012 in Global Warming with 8 Comments


Is anybody sure about the cause of global warming? One thing is certain. The answer to THAT question is NO.

A lot of people would say it is air pollution, and the newest president of the USA seems to think so. Can a new government save future generations from global catastrophe? A market for cleaner-burning fuels might help stop climate change and President Obama’s administration could make this possible. So a number of environmental groups and lobbyist groups hope.

One such special interest group is known as Ceros. This coalition of environmental organizations and investors wishes for Obama to curtail global warming. They figure he could pass legislation to reduce green house gas emissions by 25% below 1990 levels before 2020, and they might be right.

One step in achieving this end is “honest accounting of financial risks that companies and investors face from climate change,” according to Ceros. Another might be dispensing with a system of emissions credits to force this honest accounting instead of providing an avenue for deep-pocketed corporations from easily buying their way out of responsibility.

Who wouldn’t want Barack Obama’s government to take charge in reducing greenhouse gas emissions and rates of deforestation? Is this even the right person for the job? No one person can do it all, of course.

According to Obama, “The issue of climate change is one that we ignore at our own peril. There may still be disputes about exactly how much is naturally occurring, but what we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return. And unless we free ourselves from a dependence on these fossil fuels and chart a new course on energy in this country, we are condemning future generations to global catastrophe.”

This tells us that he has some regard for scientific research, and that he believes we CAN do something about Global Warming. Applying science correctly provides a good start to arriving at a solution. And scientists will play a big role in finding a solution, even if that solution is simply a “wait and see what happens”.

A scientific approach includes taking off the blinders and thinking creatively to arrive at one or several solutions. Focussing on carbon in initiatives such as the National Low Carbon Fuel Standard, which is trying to find “clean” fuels instead of the ones we currently consume, takes the sights off other climate drivers and other greenhouse gases. Water vapour being chief amongst those.

Another example, please…

It has been said that the sun is the only source of global warming. A new energy economy proposed by Obama would rely on Renewable Energy such as solar and wind, both of which depend on sunlight. Other documents have said that extra sunspot activity can reduce cloud cover, resulting in a more heated planet/atmosphere system.

Furthermore, An Inconvenient Truth shows Al Gore putting carbon dioxide as the culprit as far as global warming is concerned. Anthropogenic carbon dioxide. But a credible theory of climate variations points to Milankovitch Cycles, where changes in earth-heating patterns occur in a recurring pattern.

Maybe Obama got in at the right time with his campaign promises and we will see improvements take place that would have happened without anybody’s effort at all. Barack will certainly get the credit, though.

Tree Preservation, Tree Protection, Root Protectiong, Residential in Houston Texas

Posted by admin on July 31, 2012 in Environment Protection with No Comments


Humans have an innate love for trees. We love them for their beauty. Their structural nature-upright, spreading, weeping, columnar, contorted. Their colors-flowering, fruit-bearing, the changing of leaf color, the varieties of bark. We love them because of the way they make us feel. In fact, studies have shown that surgical patients recover more quickly when their windows provide a view of trees. We love trees for the shade they give us. Trees actually alter their environment, improving air quality, harboring wildlife and moderating the climate. Perhaps the most poignant reminder of our lasting relationship with trees is how often trees are planted in memory of a loved one or to mark a significant event.

Little wonder tree preservation gets our attention.

Tree Preservation: The Killers

The Houston area is filled with a fascinating variety of trees, from the mighty oaks and pines to the miniature ornamentals. Their chances for survival are much greater with some preservation and conservation efforts. This is offer the first part of a large scale landscape project.

Trees face three offenders when it comes to their survival during construction:

• Compaction. The main killer of trees, both during and after the construction of a home or building, is soil compaction. Soil compaction is caused by these culprits: 1) construction vehicles driving over the root zone; 2) construction materials being set down on the roots; 3) soil being piled onto the root zone, which compacts the soil and suffocates the tree by cutting off the exchange of gases in and out of the soil; and 4) continuous walking over the root system. The most common, yet overlooked, cause of compaction is foot traffic-in fact, compaction from foot traffic is the main killer of trees on a construction site. Sadly, people just don’t think it matters.

• Root damage. Root damage can come from a variety of activities, but generally it is due to digging for foundations, swimming pools, landscaping, irrigation systems, drainage systems and landscape lighting.

• Soil contamination. Soil contamination is normally due to construction materials, such as paint, turpentine, lime, cement, or acid, being left or dispensed on and near trees. Over time, these materials leach into the soil, infect it and kill the trees.

Tree Preservation: How to Lessen the Damage

There are many pro-active moves that can be made before and during construction to mitigate the damage to the existing trees on a site.

Preconstruction:

• One of the most commonsensical action items in tree preservation is to fence off the root zone to force people, trucks and materials away from the trees. Be sure to install a fence that cannot be easily taken down or breached.
• Do a deep root fertilization to the trees so that they have as much nutrition as possible during construction. It is important to start this feeding early because the feeding process takes time.

• Install a construction irrigation system to ensure tree preservation. If the existing trees had regular irrigation prior to construction, it is important to maintain that irrigation during construction. Many times, construction can go on for a year or more, so changing the irrigation-or not watering at all-can only worsen the impact of the construction process.

• Construct a path or bridge to reduce the impact of the construction. A confined path will minimize impact on the site, soil and root structure. Paths and bridges can be made of such eco-friendly materials as bark mulch, geo-grids or wood. See bridge below:

• Prune the roots to help tree preservation. If you know a tree’s roots will be cut or damaged due to the construction, yet you want the tree to remain, go ahead and trim the roots beforehand. This measure is much less stressful on the trees than having the roots ripped and torn.

Construction:

• Hand-digging for utilities, electrical, plumbing and irrigation systems goes a long way in tree preservation efforts. All trenches near trees should be dug in a radial pattern to mitigate root damage. See picture of a large pipe installed under tree roots below:

• For areas that are more sensitive, compressed air can be used to blast the soil away from tree roots. This way you can see all of the roots and run your irrigation pipes, landscape lighting conduits, etc. without cutting them. See picture below of tree roots exposed with compressed air:

• For deeper trenches or for Houston’s heavy clay soils, use a hydro-vacuum to expose the roots and navigate around the tree roots without cutting them. In essence, you create tunnels in and among the root system.
• Use root barriers in tree preservation. During construction, root barriers can be installed to prevent new and existing trees from damage due to new hardscapes, swimming pools, outdoor water fountains and landscape lighting conduits.

Post-Construction

• Once construction is completed, trees need another deep root fertilization to promote health. This treatment is especially important when you are headed into the hot months. Houston summers-all by themselves, regardless of any duress trees might be under due to construction-can be very stressful for trees.
• Aeration is another important tool in tree preservation as it promotes root growth and combats compaction.

• Inspect the trees for insect infestations, such as pine bark beetles and bores. Apply treatments as needed. Insects can kill really quickly when Houston’s weather turns hot and the trees are stressed from construction.

Tree Preservation: Why It Matters

Besides the aesthetic qualities of trees, there are some very practical reasons to put time, money and energy toward tree preservation. Energy bills are most notably affected by the presence of trees as the shade they produce helps reduce air-conditioning costs. In this ecologically-aware era in which we now live, green architects tell us that what you do on the outside of your house-like creating shade by planting trees or judiciously using the shade of existing ones-is up to seven times more effective than anything you do on the inside of your house.

Also, it’s been proven time and again that a landscaped and well-maintained yard, including trees, increases your property’s worth. “Trees are of great value to homeowners,” says Jeff Halper with Exterior Worlds. “They are more delicate than many people realize and, unfortunately, construction kills a lot of them. Since trees are such large organisms, it takes a while for them to die. So four or five years can pass before they finally do die and your builder is long gone by then.

“Another important consideration is that most upscale communities have tree replacement rules that require property owners to replace the equivalent tree size if a tree is cut down. For instance, depending on the code, if you cut down a 12-inch tree, you must replace it by using, say, three four-inch trees or two six-inch trees.”

Solar Energy a Reliable and Practical Source

Posted by admin on July 31, 2012 in Clean Energy with 5 Comments


These days we are experiencing a growing awareness to the fact that our energy resources, as they have been used in the last few years, are probably not going to last for long and that the energy markets are exposed to more and more rapid changes, some due to political reasons and others because of the changing climate of the planet.
Solar energy is a renewable free source of energy which is sustainable as it is not inexhaustible, unlike fossil fuels which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. The solar electricity that is produced can supplement your entire or partial energy consumption. Using solar energy means reducing your energy bills and saving money. Also having solar PV panels adds value to your home, they are low maintenance and unobtrusive. Germany is the global leader for solar-generated electricity.
Why choose solar energy?
Australia is the luckiest country in the world. Our geography gives us the opportunity to use the most natural, sustainable and Clean Energy in our homes – the energy from the sun.

Solar thermal applications are the most widely used category of solar energy technology. These technologies use heat from the sun for water and space heating, ventilation, and many other applications.
Solar energy is not a new concept, it has been properly introduced to the global public many years ago and successfully implemented in different parts of the world in different ways, so we can say that solar energy is known to most people, but it is still not as popular as it should be, as a cheap replacement for other sources of energy. The energy of the sun, from its direct sun rays that are projected directly at the earth or by giant wind turbines are free fro us to use, to manipulate for our needs, and this can be done by almost anyone in any place, it just needs to technology and the know-how.

A. Solar Energy
B. Hydroelectric
C. Wind
D. Biomass
E. Hydrogen Fuel
F. Geothermal

And please explain why you picked the answer , for example :

F , Geothermal , this is beacuse …….

Thanks , i need the answer+explaination by tonight .

Geothermal As A Green Energy Source
——————————————————————————————————————————————-

Geothermal energy is energy obtained by tapping heat from the earth itself. This comes from magma and the radioactive decay of uranium, thorium, and potassium.

The downside to geothermal energy is the fact that it is expensive to build. On the other hand, because the earth’s crust continuously decays replenishing the heat, it is still a renewable source of energy.

There are three types of geothermal plants around. These are namely dry steam, flash, and binary.

Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator.

Flash plants take on water at temperatures over 200 °C, out of the ground, and allows it to boil as it rises to the surface then separates the steam phase in steam/water separators which runs the steam through a turbine to generate electricity.

Last, you have binary plants. Here, hot water flows through heat exchangers and that boiling organic fluid is what spins the turbine.

Once power is generated, the condensed steam and remaining geothermal fluid from all three types of plants are injected back into the hot rock to pick up more heat.

Geothermal plants are used operational in different parts of the globe. These are usually located in geologically unstable parts of the planet. You can see some in Chile, Iceland, New Zealand, United States, the Philippines and Italy. At home, two most prominent areas for this are in the Yellowstone basin and in northern California.

If you were to compare the amount of energy collected from geothermal to solar, you still get more from the sun. Despite that, people should still use it since solar energy cannot be harnessed when the clouds block the sun’s rays from reaching the solar panels.

Geothermal energy is a green energy source just like wind, hydropower and biofuel because it is a renewable. By maximizing its potential, we don’t have to worry about the price of oil in the world market when it hit more than $110 a barrel and is now under $40 in the world market.

But that is not the only thing we should be concerned about. We should also do our best to protect the environment given that coal fired and nuclear power plants produce harmful gases and radioactive waste that may cause to people and the surrounding areas.

———————————————————————————————————————————————–

Why Is Hydropower A Green Energy Source?

Why is hydropower a green energy source? It is because we are able to harness electrical power by converting water into electricity.

The use of hydroelectric power or even hydroelectricity dates back to Ancient Greece and China when they installed waterwheels in rapidly flowing rivers to turn millstones and other equipment. Years later, this was used in the New World which is now known as North America to power saws and other equipment.

But the hydroelectric plants of today still use the same basic principles as the historical waterwheel with some variations. The difference is that we use the force of the power to push the turbine which in turn powers a generator thus generating electricity.

To make sure that there is a steady flow of power being produced, a dam has to be built to retain the water. If there is a need for more power, the gates of the dam are opened so water can be released. During non-peak, the gates are closed. To ensure there is water at all times, some dams have a recovery and pumping systems to the water released can be used again.

There are issues with the use of hydroelectricity. Some claim that it poses a problem for fish and aquatic plants on both sides of the dam. Because the flow of water has been altered, the nutrient rich silt which helps crops grow could be affected which is exactly what happened when the Aswan Dam was completed in Egypt.

Lastly, you have ocean thermal energy. Here, you get power based on the different temperatures in the water. For this to work, you need at least 38 degrees Fahrenheit difference between the warmer surface water and the colder deep ocean water. Still in the trial stage, it is used Japan and Hawaii.

Hydropower is a green energy source. It is safe to use and what is even better is that it is renewable.

My answer is : Hydro and Geothermal

How do scientists feel Global warming will affect the ocean levels?

How do scientists feel Global warming will affect the ocean levels? Do you believe Global warming is a reality or not?

Global Warming is a reality and will cause a rise in sea level. The Earth’s average air temperatures as a whole continue to increase, in some places more than others. Some places stay about the same or even decrease in temperaure.
