This Why We Need Alternative Energy Sources

Posted by admin on April 20, 2013 in Renewable Energy with 3 Comments

The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician’s world-wide are drafting policies and are making agreements to make greater use of these energy sources.

The first problem is that the fossil fuels are depleting in a rapid rate and are harder to retrieve. The consequence is that we can be facing an energy crisis in the future is we are not careful today. The energy prices will sky rocket and not be available for many individuals or countries. To avoid this doom scenario we need to find alternatives and used them to their full potential. Luckily this is already happening.

The second problem is that the fossil fuels that are widely used today are harmful for the environment. In the early seventies and eighties there were people and even scientist who preach otherwise, but today the negative effects are showing. The earth is warming up and climates are changing. There are parts in the world were there be more rain and sunshine and others parts will be come dryer then they already are. Another negative effect is that the ozone layer is getting thinner which also leads to a warming up of the earth. These two effects compliment each other and make it even more crucial to make another step in a different direction. This step will lead us to the use of Renewable Energy.

Another problem lies in the development of small economies. Because the energy prices for crude oil are going through the roof, these countries suffer even more. Many of these countries need crude oil for their electricity and means of transportation. These high oil prices have their effect on almost everything. The monthly electricity costs for households increase among others like transport cost and prices for basic products. Hence, these high oil prices make it harder for these small countries to grow there economies.

The solution for the above problems can be resolved by renewable energy. Our beautiful planet gives us the opportunity to make proper us of sunlight, flowing water, strong winds, and hot springs and convert these into energy. These energy sources are abundant and free to use. We must be sure that we convert the energy the right way, without causing other problems that can again hurt our environment. Luckily the many efforts by individuals and companies show that this can be done.

Nice Try Kyoto

Posted by admin on April 20, 2013 in Global Warming with 3 Comments

February 16th is the two-year anniversary of the inspired and contentious Kyoto Protocol.

The Kyoto Protocol is an amendment made under the United Nations Framework Convention on Climate Change (UNFCCC). Countries that ratify this protocol commit to reduce their emissions of carbon dioxide and five other greenhouse gases (GHG). Originally introduced December 1997 it went into effect February 16th 2005 with 160 Countries on board.

Of those countries the United States and Australia refused to comply with its provisions. The decision of the U.S., which produces roughly 25% of global green house gases, to bow out has been widely and vigorously criticized.

The U.S. Bows Out

The Bush administrations denial of the existence of global warming and refusal to accept the scientific evidence behind, it has been the most noted reason for U.S. non-participation, however a less publisized reasoning was the U.S. governments view that the Protocol was incomplete.

The Kyoto Protocol calls on the high-income countries and the post communist nations of Eastern Europe and the former Soviet Union to reduce their GHG emissions as of 2012 by around 6 percent compared with the 1990 levels. However given the participation criteria China, the world second largest polluter, and India, although having signed the treaty are exempt from compliance and enforcement penalties.

These rapidly developing countries will soon account for 50% of the worlds GHG emissions. The active participation of these countries is critical to the stabilization of green house emissions and the U.S. contends that letting them slide by on the honor system is a major oversight of the Protocol.

Kyoto Not Enough

Many argue that the wording of the initiative itself is flawed, maintaining that the criteria and measures of enforcement lack clear definition. Also the long-term viability of the Protocols goals has been called into question. Jeffrey Sachs, noted economist, states in an article for Scientific America; “The Kyoto Protocol takes the long-term objective of stabilization of GHG concentrations and transforms it into a short-term target on emissions reductions, with no clear link between the two.”

With the science of global warming moving from theory to fact, many nations including the U.S. have been working on legislation of their own to reduce GHG. Canada a long time Kyoto Protocol groupie reveals that 59% of Canadians feel that the Protocol is only a small part of what each nation should be doing.

In the two years since its enforcement, while there have been marked improvements, even the strictest of participants have struggled to comply. Even Kyoto Japan where the initiative was born has found meeting its commitment a challenge. Carbon emissions in Japan have actually grown more than 8% over its ’90s benchmark and Canada reports that it is 27% above 1990 levels.

Alt vs. Nuke

Countries such as China and India are in prime positions to make big contributions in the battle against global warming. As their economies are blossoming they can make the decision to take the alternative fuel path, in fact the decision could be critical to their continued growth.

The official China Xinhua agency reported on Wednesday [Jan 17th] that rising temperatures in China could reduce grain crops by over a third in the second half of this century, imperiling food security in the world’s most populous country.

While alternative fuels such as hydrogen and bio-fuels are the most touted solutions, realistically their large-scale implementation in most established nations is not going to happen anytime soon. Alternatively many support already widely established nuclear power as a more immediate solution.

The United States generates a total of 15.43 trillion kWh per year using fossil fuels costing $818.7 billion per year. By converting to atomic energy that same 15 trillion kWh of energy can be produced for around $314 billion, a savings of over $500 billion.

In November 2006 for the first time in its 32-year history, the International Energy Agency (IEA) urged governments around the world to speed the construction of new nuclear power plants. Many countries are leaning that way; China has eight atomic plants under construction and plans to build 40 plants over the next decade.

Nuclear power is cheaper, cleaner (in regard to GHG) and would be a solution to dependence on fossil fuels, but it comes with its own notorious list of problems most notably what to do with tons of radioactive waste. A nuclear solution to global warming seems to equate by making a deal with the devil to save yourself from going to hell.

Too Little Too Late

Despite increased enthusiasms throughout global communities and well-intentioned measures such as the Kyoto Protocol, when it comes down to it we may be looking at a case of “too little too late”. It is clear that we are going to need to take far more aggressive action towards Global Warming, in order to offset the effects of World population growth and increasing energy demands.

Our current actions are the equivalent of pounding laying a railroad with a tack hammer but if it is one thing mankind is good at, it is overcoming hurdles that are in the way of its advancement. Unfortunately we more than often overlook the consequences of our progress.

The question is will human ingenuity get us out of this one and are we smart enough to do it without shooting ourselves in the foot?

Datasafexl: a Brief Overview of Microsoft ® Excel Vulnerabilities

Posted by admin on April 20, 2013 in Environment Protection with No Comments

In this article, we will provide you with a brief overview of the Microsoft ® Excel security environment and examine in more detail the effectiveness of Microsoft ® Excel’s built-in protection features.

Undoubtedly, Microsoft ® Excel’s security environment can prove to be cumbersome even for experienced users. In addition, there are numerous methods which an intruder can use to bypass any security aspect of the Microsoft ® Excel application. Without a doubt, the general consensus is that Microsoft ® Excel’s security environment is weak.

The following protection measures can be employed in a Microsoft ® Excel spreadsheet

  • Password to open the workbook
  • Password to protect sheet contents
  • Password to protect workbook structure
  • Password to protect VBA code

By using a password to open a Microsoft ® Excel file, you are effectively encrypting its contents. Thus, only individuals who know this password can access any of the workbook’s contents.

Even so, the default encryption standard in the Microsoft ® Excel application is very weak and commercial password crackers from websites such as Lastbit and LostPassword can be used to obtain the password and access the contents of the file.

In addition, there is nothing that prevents a user from sharing the password with other individuals.

Subsequently, a spreadsheet developer can decide to protect the sheet contents and workbook structure so that users cannot change any formulae or the names of the sheets for example. Again, a free utility can be obtained from a website by the name Straxx to bypass these protection features within seconds.

The abovementioned utilities can also be easily used to break the password for VBA projects and obtain access to the VBA source code.

Another common technique that Microsoft ® Excel developers like to use, is to hide all sheets when the Excel file is closed. This method forces the user to ‘Enable Macros’ when opening a file, in order to be able to view the hidden sheets.

However, the pitfall with this approach is that users can still open the Excel file by ‘Disabling Macros’ and use an ‘Add-in’ to unhide and manipulate all sheets presented in the workbook.

To summarise, users can obtain and modify all the data in a workbook, even in situations where they are required to use a password to access a Microsoft ® Excel file.

This is why DataSafeXL’s (http://www.DataSafeXL.com) innovative product, “XLSafe” is imperative for your business and your sensitive data.

Solar Panel Installation: an Environment Friendly Access to Energy

Posted by admin on April 20, 2013 in Clean Energy with 4 Comments

The increasing cost of organic fuel and its hazardous effect on environment are opening the door for the massive usage of alternative energy sources. Organic fuel is exhaustible in nature and the the whole globe is worried regarding what will happen when they are exhausted. The most viable solution for this situation is to use Renewable Energy sources like sun, wind and tide to reduce the dependence on organic fuel. With the help of solar panel, you can convert the sunlight into energy to meet your daily energy requirements like heating water and production of electricity.

Solar panels can be installed on the roof of your house and connected to the in-house heating system. Solar panels when designed to heat water only are known as thermal solar systems. The collector of this system is capable of absorbing solar radiation and converting it into heat. After it, the process of heat conduction is done to transfer the heat from the collector to the water tank.

Photovoltaic systems are the solar panels capable of producing electricity. In case of photovotaic solar systems, an electrical field is created by placing a positively charged layer of silicon against a negatively charged layer of silicon. When sunshine falls on this field, electric charge is created. Then with the help of conductors, this charge is conducted to power household appliances.

There are many advantages of installing solar panel. This offers you the access to free and clean source of energy. You can check the environment pollution and reduce your fuel and electricity bills. Now, some of the states in US are offering incentives on solar panel installation. Estimates show that solar panels, within five years of installation are capable of covering the investment on it. It is definitely a wise investment if you are planning to stay in your home for a longer period.
