Introduction to Green Careers
Author: Dr Simon Harding
Think Green ! is the brand name for the alternative energy and ecology interests of the Chronos Group of companies. The name arose from members from over 20 alternative energy, including nuclear generation, companies coming together to discuss industry needs in a forum organized by the Chronos Group. Think Green has given advice, recruitment services and payrolling in Russia, Argentina, Poland, Romania, Ukraine, Hungary, Spain, Algeria, Libya, Morocco, Uganda, Angola, Australia, Philippines, China and the USA and via the Chronos Group has over 6000 contractors out in 70 locations. We have been involved in green consulting projects from the Arctic Ocean to Patagonia and welcome challenges !
Another green venture – Coberon Green Resources www.coberongreen.com is a wholly owned subsidiary of the Chronos Group. This entity has over 50 dedicated consultants in 20 countries with a range of experience in the renewable area. But this green area covers much more than energy alone. The main sectors Coberon Green operates in are:
Wind
Windmill farms are sprouting up around the world. Australia, China, India, Europe and the United States are all investing in wind as a leading source of renewable energy. The business of wind not only includes the generation and sale of power, but also the design and construction of wind turbines. Few countries rely on wind for more than a tiny fraction of their power generation needs, but many countries are interested in the possibility. The Coberon Chronos Group works with many clients such as General Electric and Gamesa with a presence in this market. Suzlon has also recently joined our forum.
Water
Coberon Green Resources has fantastic experience in this sector and as our website shows are we have great client references in this key strategic resource area in Europe and the USA. Investors see a clear opportunity to invest in companies that collect, clean and distribute water. The largest water utility company in the U.S. is Aqua America. Another company in the industry, on the purification side, is ITT Industries, which produces water purification systems that help to make drinkable water. To see the power of water, one needs look no further than China’s massive Three Gorges Dam project. This $25 billion structure on the Yangtze River will be the largest hydroelectric power station in the world. Hydropower involves a lot of technology, a lot of infrastructure and a lot of power-hungry customers. Every one of those areas holds potential opportunities for recruiters and the Coberon Chronos Group has been active here for some time.
Solar Energy
As the cost of fossil fuels continues to rise and their availability continues to decline, the future looks bright for solar energy. Two of the leading producers of solar panals are Evergreen Solar and Sunpower Corp, which both develop, manufacture and sell panels and components and will directly benefit from the increased adoption of solar power. Coberon Green Resources has a team of professionals who are dedicated to recruitment in this industry with especial success in Spain, Central Europe and the USA.
Nuclear
Chronos Consulting has a range of references in the nuclear sector including ongoing projects with Areva an active projects in China, UAE, Ukraine, Niger, and France. We have industry experts retained on a full time basis within the group and have completed many complex and remote location projects.
Fuel Cells
On a smaller scale, researchers are working with fuel cell technology to develop an alternative method of powering automobiles. The U.S. government hopes that hydrogen powered cars will be commonplace by 2020. If this technology works, there are millions of cars – and millions of consumers – waiting for it. There are companies such as Ballard Power Systems, which produces cells that can be used in from cars to power plants, and Fuel Cell Energy, which focuses on providing power options to commercial and industrial facilities. Coberon Green Resources can provide cutting edge researchers in this field.
Efficiency
Just about every aspect of efficiency is good for the environment. Energy efficient construction and appliances reduce home energy use and energy efficient cars reduce our dependence on oil. From efficient lighting to creating the paperless office, innovative companies are developing innovative products that maximize the benefit that we get from the resources that we use. Efficiency is the watchword of the day and a developing field that will create the technologies that we will use tomorrow. Some of our clients have done a great job at leveraging efficiency such as General Electric with its Ecomagination business unit. In addition Chronos Consulting has massive experience in the smart grid sector of the energy efficincy arena with project management experience in UAE, India, Europe and USA. This is in fact one of our fastest growing divisions.
Pollution Controls
Reduction is the key term here. From reducing green house gas emissions on industrial power plants to minimizing car emissions, the pollution control industry is on the rise. Every time legislation mandates an improvement in the amount of some harmful chemical that can be released into the environment, the pollution control industry responds. There are companies developing pollution control technologies such as Fuel-Tech and Versar. Coberon Green Resources has excellent references in this area. Chronos Consulting has won a green consultancy bid in the UK. The project involves the restoration and conservation of several miles of waterways and preservation of key habitat woodland tracts. Dr Simon Harding, the Chairman of the Chronos Group comments “we are very excited by this recent development for the group. This is the largest project we have undertaken to date in pure environmental services although we have been involved in the alternative energy, alternative fuels and bio-sector for a decade….” For more information please contact www.chronosconsulting.com.
Waste Reduction
One of Coberon Green’s most extensive recruitment activities is in waste reduction. Recycling has become a standard practice for many people in recent decades. Most people are aware that household products such as paper, metal and glass are reprocessed and reused, but they never stop to consider the business behind these endeavors. Of course, these aren’t the only items that are reused; waste oil, vegetable oil, batteries, cell phones, computers and even parts from cars can have a second life. Waste management companies with a large base of recycling facilities may be of interest including companies such as Allied Waste Industries and Waste Management. Coberon Green Resources has superb references in this arena of activity and active projects in Spain and Hungary.
Organics
Our organization in Scandinavia, UK, Central Europe and the USA has extensive recruitment experience in this segment. Organic farms eschew the use of pesticides, engage in sustainable farming practices and sell products that are often healthier to eat. They also engage in animal management practices that avoid the use of hormones and antibiotics, keeping those chemicals out of the food chain and out of the ground and water surrounding the farms. It’s good food – and good business. With U.S. organic food sales reaching $25 billion in 2009, there is a huge market for organic food producers and grocery stores. Some of the biggest organic food companies include Whole Foods Markets , United Natural Foods and NBTY among others.
Summary
At Chronos Consulting we believe in finding alternative energy sources and we have wind, solar, nuclear and geothermal recruitment experience nevertheless the statistics about oil speak for themselves and we need to think how to use oil in the most efficient way . For this we have the sister group Think Oil ! We have a team of oil and gas specialists without peer in the industry whose role is to facilitate the sale and purchase of Oil & Gas Assets, conduct RPO and BPO, staffing, recruitment, payrolling and software implementation and design.

About the Author
Just looking for some general tips on living greener, things such as solar panels, etc, that won’t cost a lot to implement? Of course, solar panels cost a fortune, but it’s an example. Thanks!
Hey Jenny,
I actually just responded to another question of yours too a few minutes ago. I’ve been reviewing “green” manuals lately and found something called “Earth4Energy” – It’s a great guide with detailed information on how to build your own solar and wind power. You can check out my full review of it @ http://renewable-energy-info.com/ – Best of luck to ya!
Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this position?
hey buddy no need to go for a course or so whenever u buy a solar panel a manually comes with it with complete information on how to install a solar panel and you can always go for do it yourself things search on Google you will find the installation way however i can give a basic idea about the same like there would be two major setps one is electrically installation and second is manual also you need to know that you are going for a roof mounted panel or a ground mounted one so for starting Installing a solar panel power station is very easy. There are just a few steps you need to know. First read the information on the solar panels. The information you will require is the maximum wattage, voltage, and amps or amperes.
A solar power system will require solar panels, voltage regulator, and batteries. The most common systems are 12 and 24 volt systems. The voltage regulator needs to be rated above the maximum voltage and current(amps) of the combined solar panels. The batteries will need to be deep cycle and when combined have the capacity to provide the amp hours needed for your situation.
How to Electrically Install your Solar Panels
Each solar panel will be wired to each other in parallel if you have more then one. When you wire in parallel the amps(current) from each panel will add to the total sum of current, but the total voltage stays the same. The voltage must match the rest of your system. For example, if your are using 12 volt solar panels you must be using 12 volt batteries and voltage regulator. Voltage regulator must be rated above maximum voltage and current(amps).
Connect the output from the solar panels to a properly rated regulator, solar panel voltage regulators are rated by maximum voltage and amps, that will shut off the current flow to the batteries once the batteries are sufficiently charged there by preventing damage to the batteries.
The way that you figure the rating needed for the regulator is by adding the maximum amps for each solar panel, this should be listed on the solar panel, and if they are 12 volt panels and they are connected in parallel then max voltage should be around 22 volts. It’s the amperes that is most importance when choosing a regulator. For example, a 50 watt 12 volt solar panel will give you around 3.5 amps max output, your voltage regulator needs to be at least rated above this vcalue. Any less and your going to cook the regulator and possible damage your batteries.
Solar panels are very sturdy, it’s hard to damage them electrically. On the other hand it’s very easy to damage the regulator and batteries. Batteries can explode if connected wrong, so be carefully when working with batteries. Positive to positive and negative to negative.
hope this will help you
Planets are in solar systems, solar systems are in galaxies, and galaxies are in the universe, so what is the universe in? How can something just be here? A theory of mine is mabey the universe is God. Perhaps it is a living thing. Since nothing on earth will ever know the true answers all I can do is speculate. I personally don’t think the answers will be found by math, which was created by humans.
“The universe is nothing more than an atom of a larger thing. An atom in your fingernail could hold an entire universe in itself.”
You got that from animal hour didn’t you? When i first heard that I thought, “cool” but then I thought about it just a little harder and realized that obviously isn’t possible and if it was, what would happen when the life form our universe is an atom of dies or whatever it is part of is destroyed?
The universe means, literally, everything that exists. Asking what exists beyond the universe is like asking what continents exist outside the Earth. If we can use reason to divine it’s existence, then it is part of the universe.
People of course speculate. Anything not of this universe is termed “supernatural”. And because the supernatural can not be falsified (proven wrong), then it is not a truly scientific question. So your calling the universe ‘God’ (a philosophical thought that has existed for decades. Google “pantheism”) is purely arbitrary, faith based, unfalsifiable, and thus, not proper scientifically.
As far as knowledge, the acquisition of knowledge and search for the truth has always been sketchy, but it is hypothesized that when we unlock the secrets of consciousness, we will finally have an objective standard for the truth, and that will change our society in profound ways. Possibly, we are on the verge of understanding consciousness, as neuroscientists delve further and further into the brain, unlocking mystery after mystery, we may eventually have a full understanding of how our brain creates ideas, and we can gauge which ideas have a proper base, and which do not.
And your comment about math is conceptually wrong on so many levels it’s hard to count. Man didn’t ‘invent’ mathematics anymore than he ‘invented’ electricity (Electrons have always existed, Man simply discovered them and their uses).
Einstein once wrote that “Mathematics is the language with which God wrote the universe”. Of course Einstein was being metaphorical about God, but the point is that 2 + 2 = 4, no matter how many people are counting.
Even Descartes, who coined the term “I think, therefore I am” and who couldn’t be convinced that anything in the universe except his own conscious mind existed, believed that conceptual mathematics were the only universal constant, the only thing man could truly trust as existing.
I CAN’ T TELL THE DIFFERENCE BETWEEN SOLAR WINDS AND SOLAR STORMS. AND WHAT STARTS A SOLAR STORM/WIND
The solar wind is the stream of particles and radiation continously emitted by the Sun and affects bodies in orbit around it. For example the solar wind produces magnetic and radio interactions with the Van Allen belts around the Earth.
http://csep10.phys.utk.edu/astr162/lect/sun/wind.html
It might also be used to propel a giant sail as a means of interplanetary travel some day.
http://www.electric-sailing.com/
The Sun is a very agitated body, with massive and rapidly changing magnetic fields and mass and radiation movements which can lead to violent eruptions and mass and radiation emmissions called solar storms. Coronal mass ejections can throw out tens of thousands of tons of matter in minutes, accompanied by severely increased levels of emmitted radiation. Increased material and radiation loss from storms of course adds to the solar wind, but the massively increased emmissions during storms can mess up comminications on Earth and even shut down power stations.

http://solar.physics.montana.edu/press/WashPost/Horizon/196l-031099-idx.html . . . . .
http://www.foxnews.com/story/0,2933,478024,00.html . . . . . .
Using the sea as an analogy, the solar wind is the like normal series of waves and swells ever present on the oceans. Seismic storms from earhquakes and volcanos generate the giant waves and tsunamis that wreak havoc where they reach land just as the massive radiation levels of solar storms do when they reach the magnetic and electrical fields around a planet like Earth.
Tsunamis are only dangerous when they reach the lower water depths off-shore and the nature of the wave is forced to change.
When they hit the land the waves are forced to give up their energy the full force of the waves is felt.
In mid ocean there is nothing to interact with and nothing to harm.
Likewise with radiation storms. It’s when they reach a magnetic or electrical field with which they interact that the harm is done.
Human aliens of course from other solar systems that mixed with Earthlings long ago to create different races and religions on planet Earth.
Perhaps we may be descendants from different planets, and there may be less than half of the people on Earth who are true blooded native Earthlings? Wouldn’t this explain a lot?
What do you think?
I have considered that humans on earth may advance technologically enough to be able to travel to planets in other solar systems and galaxies Since our Earth won’t be viable for human life forever, we will need to do that for humanity to survive.
. If that is so, then maybe we will find life forms similar to ours somewhere else in the universe.
And perhaps life somewhere else in the universe has already developed ahead of ours, and those people have had the technology to travel here.
A lot of solar hot water systems claim to also increase the value of your home but provide no real information regarding it. Who would determine this value or how might it be applied to the value of the home? If it does increase does this increase depreciate?
Yes of course it increases the value the real question is does it increase the value as much as it costs to install it. A smart Realtor might be your answer.
I was wondering how many solar cells you would need to power a small toy car. I don’t have a lot of knowledge about things like this, so if you could direct me to any websites or explain it, that would be great, thanks.(:
Well, first you need to figure out what your requirements are going to be, for example lets say 5v. Solar cells are cheap, these ones here are .55v http://www.radioshack.com/product/index.jsp?productId=2062564. You see that metal strip up top? That is the – and on the opposite side that is the +. You need to solder some wire on both ends and that is kind of tedious if you are not familiar with soldering so you can always get one of these. http://www.radioshack.com/product/index.jsp?productId=2131051 The wires are already soldered and it is in a nice little case too so it is protected.
The one I linked is 6v though and you need 5v (like I said earlier for example). Since solar panels do not give consistent power since it depends on how much light they get you would need a voltage regulator. http://www.radioshack.com/product/index.jsp?productId=2062599 That is a 5v voltage regulator, meaning no matter how much light the solar cell is receiving it will only put out 5v, unless it is getting less than 5v of course. So it might be a good idea to get two of those 6v solar cells and connect them in series (connect the + to – of the two cells so the voltage goes up to 12v). The amperage may be an issue but this will depend on the load requirement as well, if it is just a small motor those cells should work fine. Send me an email if you are curious how the voltage regulator is wired up. To recap:
1. Find out how much voltage/amperage your toy car is.
2. Buy solar cells for those needs.
3. Buy a voltage regulator for steady flow.
4. Profit, easy as that.
Price of Solar panels Vs Utility – is it really worth going for it?
The current wholesale price of solar panels from China is €0.46 per Watt peak (which means 32 Rupees per Watt peak).
http://www.enfsolar.com/cell-panel-prices
A typical panel is 250 Watt peaks. Which makes the panel €115 / 8000 Rupees. Of course buying small amounts locally will put up the price.
People normally install 2,000 to 4,000 Watt peaks on their home. Historically people install panels to get special tariffs and these haven’t really existed for homes in India. But the price of panels have dropped dramatically in recent years and they are starting to become cheap enough to be interesting without government subsidies, but payback will still be very long.
I want to setup solar panels to run 2 Air conditioner and simple lights. How much would be the approx cost in USD? I want to set it up India. If you’ve more idea about Indian market then thats better.
This means that what you would be powering with solar electricity are things like the refrigerator, the lights, the computer, the TV, stereo equipment, motors in things like furnace fans and the washer, etc. Let’s say that all of those things average out to 600 watts on average. Over the course of 24 hours, you need 600 watts * 24 hours = 14,400 watt-hours per day.
I know that a solar panel can generate 70 milliwatts per square inch * 5 hours = 350 milliwatt hours per day. Therefore you need about 41,000 square inches of solar panel for the house. That’s a solar panel that measures about 285 square feet (about 26 square meters). That would cost around $16,000 right now. Then, because the sun only shines part of the time, you would need to purchase a battery bank, an inverter, etc., and that often doubles the cost of the installation.
If you want to have a small room air conditioner in your bedroom, double everything.
If you want to just power 2 small air conditioners, your look at about $32,000 +installation
Why can solar energy be not used everywhere? Is it very expensive to tap it?
Solar energy is (or was) very expensive, yes. That is changing. current costs versus long term power production are falling, however. At present, the cost is borderline.
However, solar energy alone is not a complete answer. First of all, for the production of electricity, it has some problems. The main one, of course, is tha tit doesn’t work at night. You either need a storage system (batteries) or an alternative source when it’s dark or cloudy.
There are alternatives which, combined with solar energy, can replace coal. Wind, existing hydroelectric systems, nuclear energy, and tidal power are some of them.
Myy point is, don’t fall into thhe trap of fixating on a single all-encompassing cure-all technology. We need a mix of technologies. That’s true today–we use coal, oil, nuclear, hydroelectric, and other sources–a mix of technologies to provide our energy needs. We need to change themix–eliminating fossil fuels and incorporating new technologies to replace those fossil fuels. There is no simple solution.
Now-as to oil–it is used primarily for transportation. In some ways it is ideal: its easy to store and the fuel stores the energy, whichis released when it’s burned.
There are alternatives. The one I think the most practical is to use electric cars. Current technology makes electric cars with performance and adequate range possible at prices comparable to gas-powered cars (once they are produced in large numbers as gas-powered cars are). That’s acutally a solved problem. What we do not have is a way of producing the electricity to power all those cars (without buring oil or coal, which defeats the purpose) at present. For that–go back to the first part of this post.
But we also do not have a practical infrastructure to deliver that electricity to a fleet of 150 millioncars (in the US). That is not a trivial problem. Think of what it takes to deliver a gallon of gas from an oil well to your car. Here’s the sequence. Oil well to pipeline (hundreds of miles) to refinery to another pipeline to atanker truck to an gas storage tank under a gas station and then a pump to take the gas out o fthe tank and deliver it to your car.
And remember, you need tha tinfrastructure so comprehensive that it blankets an entire CONTINENT.
You will need the samme for electric cars (or any other alternative).
I don’t mean to discourage you–this is doable. We DID do jsut that in the early 20th century to make our current system of gs-driven cars possible. But that took decades–and a hellava lot of engineering and research.
But–as to your question–we wil get solar power on a large scale in the foreseeable future. But we will need a lot more. It’s a complex problem–and a big one.
