As people become aware of the dangers coal and oil present to the environment, more and more are looking at clean solar power. To determine whether it is an option for you, its best to learn a bit about it first. Solar power can have several long term benefits for you.

About Solar

Solar power at its basic is energy created from sunlight. The power can be generated directly from the suns light with the use of photo voltaics, or indirectly with what’s known as concentrated solar power. This is when sunlight is concentrated on a focal point, and the heat generated boils water that turns turbines and generates electricity. Solar power has the potential to generate many thousands of times the total world output of energy. Yet in 2009 only accounted for 0.02% of the total electricity produced worldwide.

If solar power use could double every 2 to 3 years, it can become the dominate source of energy for the century. The biggest solar power plants, are concentrating solar thermal plants, although new multi-megawatt photovoltaic plants have also been created. More and more countries are investing in the bigger photovoltaic power stations, like Germany and Portugal.

More Solar Power

Terrestrial solar power is a predictable and intermittent source of energy, which means even though solar power is not readily available all the time, people can still predict it using a certain degree of accuracy when the energy source will or will not be available. A number of technologies, like the solar thermal concentrators, include an element of thermal storage, such as molten salts.

With the use of orbital solar power collection, the intermittent variable is taken out of the equation entirely. Although the launching of satellites to gather then beam the energy are required, this option will be available sometime in the future. The intensity of the sunlight above our atmosphere makes this type of collection a lot more efficient.

About Solar Energy

Humans have long used forms of solar energy. Secondary sources of solar power such as hydroelectric, wind, wave and biomass comprise the majority of our solar energy usage. Only a fraction of the vast available solar energy we receive is ever used.

Solar powered electrical generation depends on photovoltaics and heat engines. The uses of solar energy are only limited by human ingenuity. Some of the other uses of solar energy include space cooling and heating via solar architecture, solar hot water, solar cooking, potable water via distillation and disinfection, day lighting and high temperature process heat for industrial functions. Solar panels are one of the most effective and basic ways to gather solar energy.

There is no doubting the importance that renewable energy will play in the future. As a planet, our fossil fuel resources such as oil, coal and gas are finite. Therefore, we must search for and develop alternative fuel sources if we are to survive and thrive in the future. There is an additional problem with burning fossil fuels as they increase CO2 levels in the earth’s atmosphere. As we all now know, that leads to a dangerous increase in a global temperature.

Making the search for a clean and renewable source of energy a top priority for the future will help us save this planet and preserve our way of life. We cannot live forever on finite resources and so it makes sense to turn to renewable. The challenge now is to make sure renewable energy is effective and accessible to all.

Much research has been performed in this area and action has been taken. Billions of dollars are being spent in labs all over the world on developing new renewable systems that will help us in the future. When we think of renewable energy we think of something new that is synonymous with innovation and discovery. The truth is that these resources are as old as the earth itself;we just lacked the will power and ingenuity to fully harness all that power. That has changed now. We can view renewable energy has being a new phenomenon due to the wonderful technologies that have recently been invented so as to harness its power. This energy harnessing technology is a modern scientific wonder, but harnessing renewable energy is certainly not a new discovery.

Many years ago it is true to say that we derived energy from different sources. The first humans relied on the energy intake from eating food, but as things evolved through the years the early humans learned how to use various tools to exploit energy potential. They could overcome their limitations with these tools and soon with the development of an agrarian society the humans could exploit agrarian energy. One of the earliest examples of the harnessing of wind power by early humans was the invention of a sail by the ancient Egyptians. This led to an age of discovery as new modes of transport allowed them to travel further and further.

The invention of the windmill in the first century marked a further development in wind power, with the windwheel of the Greek engineer Heron of Alexandria one of the first known instances of wind powering a machine in history. By 1000 AD windmills were used extensively across the Middle East, and spread quickly to Europe. Today, wind power is one of the world’s fastest growing energy resources using non-emission wind turbines to make electricity.

What is CPTED? The official book definition is “the proper design and effective use of the built environment that can lead to a reduction in the fear and incidence of crime and an improvement in the quality of life.” It is simply a goal to reduce opportunities for crime that may be inherent in the design of structures or in the design of neighborhoods. In other words, make your home or neighborhood unappealing to burglars and thugs.

Cities and Counties throughout the country are adopting CPTED ordinances requiring site plan reviews with crime prevention in mind. Law enforcement officers who are specially trained in CPTED are now working closely with Planners, Architects, City Officials, and Educators to ensure the proper design of structures, schools, and neighborhoods. These experts know how the design and use of the environment can control human or criminal behavior and reduce the fear of crime. They used natural means such as landscaping to deter criminals. Access control, natural surveillance, different aspects of lighting and its effects on human behavior, all deter crime.

Many landscape specialists incorporate CPTED into their layout & design of landscapes. Each of the following CPTED strategies are low cost guidelines that they apply to reduce the fear and incidence of crime and improve the quality of life.

1. Natural Access Control guides people entering & leaving a space through the placement of entrances, exits, fences, landscaping & lighting. Access control can decrease opportunities for criminal activity by denying criminals access to potential targets & creating a perception of risk for would-be offenders. Walkways & landscaping should direct visitors to the proper entrance & away from private areas. The design should create a perception of risk for would-be offenders. Walkways should be installed in locations safe for pedestrians & keep them unobscured.

2. Natural Surveillance is the placement of physical features, activities & people in a way that maximizes visibility. A potential criminal is less likely to attempt a crime if he or she is at risk of being observed. At the same time, we are likely to feel safer when we can see & be seen. The landscaping should be selected and installed to allow unobstructed views of doors & windows. The front door should be at least partially visible from the street. Shrubs & bushes near windows should not restrict full visibility of the property. Sidewalks & all areas of the yard should be well lit.

3. Territorial Reinforcement is use of physical attributes that express ownership such as fences, signage, landscaping, lighting, pavement designs, etc. Defined property lines and clear distinctions between private & public spaces are examples of the application of territoriality. Front porches or stoops should create a transitional area between the street & the home. Property lines & private areas should be defined with plantings, fences or retaining walls. Use thorny plants along fence lines and under windows to deter access by intruders.

4. Maintenance is a well maintained home, building or community, and creates a sense of ownership. A well kept area tends to make someone feel like they will be observed by neighbors or business owners as it is obvious people care about the area. Keep trees & shrubs trimmed back from windows, doors & walkways. Keep shrubs trimmed to 3 feet & prune the lower branches of trees up to 7 feet. Use exterior lighting at night & keep it in working order. Keep litter & trash picked up & the yard neat & free of items that might attract theft.

Computer recycling refers to the practice of salvaging useable components from obsolete electronic devices or safely disposing off electronic devices. It is a practice that each one of us must inculcate because inappropriate handling of discarded computers and other electronic devices can cause environmental hazards.

Studies estimate that over 40 million electronic pieces become obsolete annually. These pieces have constituents such as lead, cadmium, barium, and mercury, which are hazardous to the environment. In a landfill, these materials seep into the ground and then into our food and water supplies. This can cause serious health concerns over a long period.

Obsolete Computers: Environmental Threats Obsolete computers that are simply dumped in the garbage drums are the biggest threat to the environment. The computer monitors have cathode ray tubes containing four to five pounds of lead that contaminates the environment acutely. Besides lead, the computers have many other hazardous elements such as mercury, cadmium, and hexavalent chromium. When inhaled over a long period, these elements cause high blood pressure, liver and nerve disease, blood with poor iron, and even brain damage to the exposed group. This causes great concern, considering several million computers become obsolete annually.

Therefore, we must handle the obsolete electronic devices carefully. Moreover, different Environmental Laws have banned the illegal landfills by the disposals of computers and other electronic equipment. These laws necessitate sending the un-functional computers to a reputable recycler for harmless recycling. The laws also specify the need for regular recycling to avoid such computers from piling up.

There are several methods to deal with old computers. Some of them are as follows:

Give It For Reuse: If your computer is in a decent condition, you can sell it to a company or an individual so that it can be used further, or simply donate it to someone needy.

Trade It In: There are many computer dealers (e.g. HP) who offer trade-in promotions on computers and peripherals.

Auction It: You can sell the computer on eBay or any other auction site. You can also organize a quick garage sale and see if any of your friends or neighbors wants the computer.

Set up a Server: You can continue using the old computer as a server to store and share data.

Salvage Some Parts: You can see which parts of your computers are in good working condition. You can salvage those parts and use them in your new computer.

Go for computer recycling and safe the planet earth!

Environment awareness has increased around the world together with the necessity for better regulations that will allow automotive salvage become a safe environmental occupation. Under law enforcement, automakers should take care of their products from cradle to grave. Carmakers are subjects to great international pressure and urging that all dismantled car pieces, wrecks and carcasses should no longer pile up in waste metal yards, but be reused or recycled.

Is it just metal piling up in salvage yards, which has brought automotive salvage into the spot light? Only partially; as there remains the risk of chemical pollution and infestation due to all the vehicle fluids that pollute the soil, should there be any leakage. Those company owners that deal in car dismantling should follow some general basic environmental security rules when fragmenting cars to pieces.

The best way to minimize spill-over during automotive salvage operations is by evacuating fluids before dismantling and depositing these fluids to safe tanks or containers. Fluids should be immediately removed from all the constituents of the vehicle. If this were not possible, check for leaks, and in case you find any, isolate them and reduce the risk of contamination.

The fluids that result from dismantling automotive salvage should be kept in safe containers or tanks. These should be labeled and inspected on a regular basis in order to prevent alterations or leaks. In case they are deposited outside the salvage yard, they must be equipped with a double protection system from the external environment.

One great advantage that automotive salvage has is that it makes possible the reduction of the production price per component in big vehicle companies that can invest in recycling items or reconditioning them for reuse. Some automakers are also talking about increasing the number of recycling points, where automotive salvage might become the starting point for alternative building materials.

The question that has brought much heated debate is: “To whose expense?” Who pays for automotive salvage that is for dismantling, for reusing, for recycling? The answer to this may be the answer to a whole bunch of environment issues that originate in careless automotive salvage in junkyards.

Managing the automotive salvage yards would dramatically reduce the amount of scrap that fills the land. There are thousands of independent automotive salvage yards owners who need a efficient recycling system as they see the pile growing on their property, as not all of it can be sold or re-used without reconditioning.
