What’s the difference between renewable energy and environmental resources engineering?

Posted by admin on October 27, 2012 in Renewable Energy with 2 Comments


Oregon Tech offers Renewable Energy engineering and Humboldt State offers environmental resources engineering. When I look at the differences between these 2, I couldn’t tell so what should I do? I’m a senior in highschool with a 3.6 GPA.

Environmental engineering science is a multidisciplinary field of engineering science that combines the biological, chemical and physical sciences with the field of engineering.
And Environmental engineering is the application of science and engineering principles to improve the natural environment, To provide healthy water, air, and land for human habitation and for other organisms, and to re-mediate polluted sites. It involves waste water management and air pollution control, recycling, waste disposal, radiation protection, industrial hygiene, environmental sustainability.

Renewable energy and natural gas are best friends

Posted by admin on October 27, 2012 in Renewable Energy with No Comments


Solar energy is great. But in a ‘low-on-sun’ country like Belgium, you’re better of with a system which combines solar and traditional energy.

TBWA Belgium’s new commercial shows ever so gently how Renewable Energy and natural gas go together very well, hand in hand, as best friends.

The film was directed by Olivier Babinet and produced by Lovo Films for the Belgian Natural Gas Association (KVBG-ARGB).

Thanks to the people who helped ‘knitting’ it together.

How You Can Convert Your Home Into a Complete Source of Renewable Energy

Posted by admin on October 25, 2012 in Renewable Energy with No Comments


A few years ago Renewable Energy such as solar power and wind power was an impossible dream for the average person. Why? It was very very expensive to turn your own home into a solar power generator. In fact you were unlikely to ever make your money back with the energy savings. But recently all of that has changed.

Both solar power and wind power have become genuine alternative energy sources in the last few years. And the best thing is, you can create working generators and plates/turbines yourself, for very little cost. This means you will be saving thousands of dollars making them, and then thousands more when they are up and running.

Has there ever been a better time to get green? Not only is electricity the most expensive it has EVER been right now, but the planet is also in the worst shape it has ever been. What do these two things mean for you? They mean you should try and generate some of your power (even if you only decide to make 20% of your own power).

It is not hard to get the materials, and as long as you have a good manual to follow you should easily be able to implement your own system and start saving money on your bills. Solar power is ideal for just about any home in America (amongst other countries). Wind power is ideal for higher up (hilly terrain) locations or large flat locations. On top of saving a lot of money or your bills you will find yourself having fun with a great family project.

Global Warming – Modern Chimneys Can Help

Posted by admin on October 25, 2012 in Global Warming with No Comments


Much ado has been made about “solid fuel” heating devices.  A solid fuel heating device is, simply, a fireplace or chimney–a unit in which something is burned and the heat from that fire is transferred throughout the house while the dangerous components of the fire (smoke, soot, etc) are transferred out of the house via a chimney or piping system.  You might consider a fireplace and chimney system to be old fashioned (and a lot of work) when compared to other heating systems, like underfloor heating, which have become popular in the last few decades.  The truth is that solid fuel heating systems can help reduce your carbon footprint and Global Warming.

Here are just a few of the major benefits offered by a solid fuel heating devices:

* Money goes farther with a solid fuel heating device than it does with a modern heating system.

* Versatility is greater with a solid fuel heating device than it is with the other types of heating devices that can be installed.

* The solid fuel heating device offers users more control than some other types of heating devices.

* There is nothing more reliable than a solid fuel heating system. 

These factors aside, solid fuel heating devices are not without risks.  UK homeowners need to make sure that their chimney systems get cleaned regularly or they run the risk of getting carbon monoxide poisoning.  This is because the chimney system is the mechanism by which carbon monoxide and other dangerous materials are removed from the home.  There are many mechanisms that can be built into modern solid fuel heating devices that help to keep the chimneys unclogged and easier to clean.  Inspect these mechanisms regularly and hire a professional to check your entire system on a regular basis.

You can save yourself a lot of worrying over your energy bill when you have a solid fuel heating device installed.  Instead of using power to turn the system on and off you simply need to find something that is safe to burn.  Gas fireplaces are another option as they can be turned on and off with a switch.

Some homeowners use them as a convenient way to get rid of junk mail or other burnable items.  Homeowners like that they have control over the units.  Other homeowners like gas fireplaces which are turned on and off by a switch.

Finally, unlike some of the other types of heating systems which have become popular, solid fuel heating systems do not rely upon electricity for operation.  You don’t have to worry about freezing if the power goes out in the middle of a winter storm.  This means that having a modern chimney can reduce your carbon footprint!

How Does Mining Affect the People?

Posted by admin on October 25, 2012 in Environment Protection with 2 Comments


Mining is destructive to the environment as trees and vegetation are cleared and burned for mining. Natural minerals and metals are stripped from the soil. In fact mining is one of the causes for deforestation. When environment is drastically affected, naturally the people will be affected.

The mining pits dug during land dredging mining remain as stagnant water pools serving as breeding ground for mosquitoes and other water-born insects.People living near such water pool areas have high possibility of getting water-born diseases such as malaria. The gravel, mud, and rocks displaced during river dredging mining disrupt the natural flow of the river. As a result, fish and other aquatic living organisms often die and fishermen find it very difficult to navigate in the obstructed rivers. Sand and gravel mining may sometimes pave way for contaminating the groundwater.

Chemicals used during mining process causes pollution to the environment, animals, and people.The chemicals such as cyanide, mercury, or methyl mercury used to amalgamate the metals and minerals extracted by mining are discharged into rivers, streams, bays, and oceans, thus contaminating the water bodies and the aquatic organisms such as fish living within the water bodies. People who consume such contaminated aquatic organisms are prone to serious health hazards. The contaminated water cannot be used for bathing, drinking, cooking, or washing clothes, thus creating water scarcity problem for people living nearby.

The toxic waste from mine tailings flow into either an abandoned mining pit or adjacent forest in the case of land dredging and pollute the river in the case of river dredging. The people who are exposed to the toxic waste from the tailings suffer health problems. They may suffer from skin rashes, headaches, vomiting, diarrhea, etc. Some mining involves the unintentional dispersal of heavy metals, such as lead, into the atmosphere. This can have serious health effects such as mental retardation in children. Asbestos dispersed into the environment during asbestos mining is life threatening for local residents and workers.

People living near mining areas or mining villages are very much disturbed and affected by the impact of mining. Theft, drugs/alcohol, prostitution, rape, cultural degradation and sexual abuse are unfortunately some of the worst problems of people living in mining areas. The poor people who face the health problems of mining cannot afford for a medical treatment, or the people who live in a remote village where a doctor is not accessible remain untreated for their illness.

The mining operators and their families may also face problems. The miners also have life risks when they are working in the mine. The family of small scale miners may suffer from financial and protection problems as the miners leave their family in search of work.

The effect of each proposed mining process on the environmental should be analyzed before granting permission to proceed mining. For example, the mining and use of asbestos are banned in most parts of the world life as asbestos dispersed into the environment is life threatening for people for several years.

Thus deforestation, mineral/metal depletion and chemical pollution due to mining can have unfavorable impact on the environment, aquatic habitats, people, animals, and of course the mining operators . Mining operators must be aware of the impacts of their mining operations, adopt self safety measures and ensure minimum risk to the environment and people.

Clean Water: Tapping the Power of Forward Osmosis

Posted by admin on October 25, 2012 in Clean Energy with No Comments


A recent article in Science Daily describes a process through which a Yale doctoral student and his mentor are reusing and desalinating water.

The world’s water consumption is forcing scientists to come up with creative ways to provide more water for the world’s growing population. The undeniable fact is that we use more water than is available through the hydrologic cycle—the continuous movement of water on, above, and below the surface of the Earth.

The student, Robert McGinnis, and his mentor, Menachem Elimelech, have devised a process that uses the power of osmosis to harvest fresh water from sources that are not normally potable, including seawater and water that is considered dirty. By using low temperature heat, the scientists are able to desalinate water and also remove contaminants. This makes water that is usually unsanitary or unhealthy available for human consumption.

The scientists are using a system they call “forward osmosis.” This draws pure water from contaminated water, using heat to push the water towards concentrated salts. It is relatively easy (for scientists) to remove pure water from concentrated salts. The process uses little energy and effectively produces clean water for consumption.

The low level of heat (energy) necessary to facilitate the changes in the water has the water industry paying attention. It is currently an expensive process to desalinate and decontaminate water. But now, with this new process, clean water is attainable, and uses low levels of energy, making it an affordable and timely process for companies to implement.

Today’s population is a burden on the planet. Our natural resources are diminished. It is imperative to find environmentally sound methods to generate more resources. The forward osmosis process described above provides an encouraging sign that scientists are on the right path, that in time, and with concentration, our population problem will be assuaged by means of smart technology that uses low levels of energy and yields tremendous levels of clean, healthy water.

Whether you are a scientist, industry specialist, or concerned consumer, information about clean water methods are readily available. While the information in this article may pertain more directly to industry and science-oriented people, it has a direct line to the consumer, which, in the end, matters to us all.

BSR Fuels Report; Rezidor Hotels to Reduce Energy; Germany Caps Subsidies- Energy Min 10/17/12

Posted by admin on October 24, 2012 in Renewable Energy with No Comments


BSR has published a new report that analyzes the sustainability impacts of commercial transportation fuels. The report, the first in BSR’s “Future of Fuels” initiative, looks at six types of current and emerging fuels: gas and diesel, natural gas, biofuel, hydrogen and electric power, to determine the fuel that is most efficient. The report also assesses the market outlook for the complete range of fuels.

The Rezidor Hotel Group, parent company of Radisson Blu, Park Inn, and Missoni brands, will reduce its annual energy consumption by 25 percent by the year 2016. Called “Think Planet,” this initiative will reduce energy at Rezidor’s 350 hotels in 70 countries.

Germany plans to cap Renewable Energy subsidies when capacity reaches national targets. The state would end payments to wind and biomass as limits, which have not yet been set, are achieved. The German government is trying to cut the cost to consumers of its decision to phase out nuclear power following the nuclear plant accident in Japan.
