"At the core of any renewable energy business are people attracted and dedicated to bringing about change; change in policy and change in the ways that we traditionally conduct business. Despite the present bumpy road, we are confident in ourselves that just around the corner things will turn around, we've worked too hard for this to fail; it's in our human nature to succeed."

Dawn, good article. Students at job fairs often ask me where the opportunities are within the clean tech sector. Which areas do you see as best for new grads? For workers transitioning from other industries and trying to leverage their skills into green? What are the job titles/responsibilities in demand today, and as we go forward? Thanks for any insights... Regards, Chris

I admit to Blue-Green colorblindness, but are plumbers, HVAC techs and electricians blue-collar or green-collar? They install renewable energy systems and efficiency improvement equipment during the course of most projects. Perhaps all jobs are a little green-collar along with white or blue.

There seems to be a lot of wishful thinking about millions of new jobs opening up and the transferability of old industry skills. It seems that most of the new jobs will be in construction with some in manufacturing; or they will be low-paying labor in the recycling industry. There will be room for only so many CEO's and engineers.

International Magnates Go Against the World's Trend by Investment in "Solar Thermal Industry"—News Release on Goldman Sachs•CDH•Himin Strategic Cooperation Is Held in Beijing
News release on Goldman Sachs·CDH·Himin strategic cooperation is held in Beijing on Dec. 12th. The first investment from these two international investment organizations is up to 100 million US dollars, actively speeding up Himin's going public. Xiang Huaicheng, former chairman of National Council for Social Security Fund,P.R.C. and former Minister of Finance, P.R.C., said on the conference that, under the circumstance of extensive impact of international financial crisis, contrarian investment to Himin undoubtedly demonstrates the great accreditations by Goldman Sachs and CDH Investments to Chinese solar thermal industry, which braces up Chinese enterprises to a tremendous extent.
According to Wu Shangzhi, president of CDH Investments, two principles are followed in selection of companies to invest, development prospect and the leading position of the company in its industry. "It takes CDH 9 years to trace Himin and make the decision, Goldman Sachs has also spent 5 years." said Mr. Huang Ming, board chairman of Himin Group, industrial vice-president of ISES.

Due to the advantage of fresnel refectors power technology ,it has obtained rapid development.
The coated steel tube is applied to the compact Linear Fresnel power plant for the receiver and the solar air conditioner.
Our company has scale production capacity for coated steel tube, (maximum absorptance 95%,minimal emissivity 9%,keep stable in 300~350℃ ) and been installed in Spain and Australia (twenty years of proven reliability).We can also provide the AR-coating glass and the mirrors.
It's very nice to find cooperator and improve the development of the concentrating solar thermal power together.

This article is good news for this country that everyday is loosing thousands of jobs . Now it will be nicer if everything that have to be manufactured (that goes with the alternative energy industry) could be built in the US. We have become too dependent on China to manufacture everything for us and our manufacturing industry is almost non existent.. So why not build all the wind turbines , blades and towers here along with all the photovoltaic solar panels too.

This is great as long as there is focus on the residential side of the market. For every 1, commercial, grid tied, government subsidised installation available, there could be 1000's of residential installations. This is where the true green collar jobs will be available. Large grid tied systems would require professional labor. I've even seen the Union recently advertising installing solar on tv. Will they take over the market using only their work force, while blocking jobs for those in the private sector? Smaller dedicated systems would seem to be the way to go to create more jobs in both the installation and manufacturing sectors. This also seems to be the right thing to do when considering our aging grid. The recent ice storms in the north east and central US should confirm this. 1000's still without power. This should make us rethink of how we use this technology to benefit the people not the big guy. Small, local, solar powered generating subsystems could provide power for several blocks on a daily basis. Many of these systems could create many jobs.
Larger systems would only be beneficial when the grid is up. The grid itself would have to be upgraded at consumers cost to handle the extra load. And this work would be done by professionals, not unskilled, green collar workers who need the work. And now that the government is putting their two cents in, in a technology that they seemed to show no interest in before, we can only expect the worst.
This technology has been available for many years and has been available to the public for many years as well. Why is it now that the gov. is jumping on the bandwagon? What do they expect to gain? What are we going to lose? Why are all the oil companies buying up the solar companies? Why do they encourage grid tie and do not even bring up private systems? Why is solar hot water never mentioned? Where is the passive design element for free light and heat mentioned?

It is these simpler technologies that will created more job growth than the more complicated systems.
Though this country is starting to get the idea, we cannot let the government and their cronnies make the decision of who gets what and who will install it. This will only benefit them as does all their actions and we the public should know this by now. We do not need them to buy something that is already available to us. It is up to us, the public to make the decision on our own. Increased sales for the public would increase manufacturing and installations, thus creating jobs for ourselves.
Educating the public on these issues should be the priority at this time. If we let the gov. tell the public what is what, we can only assume that they will be lying to us, as usual, to benefit themselves.
Here in MA, our governor, D. Patrick got on the stand and told the power companies to step up their pace to repair the grid from the recent ice storms. Why didn't he go out and help them himself. I am sure he is not even closely qualified to do such work, yet he has the gaul to make the public believe he has some control of how fast someone can install a new power line or transformer. This should be some indication of the wool that is being pulled over the publics eyes by our gov. once again.
Maybe it is best to get our lending institutions on board instead to help small renewable businesses develop. Then maybe you will see job demands increase.
Off the solar subject, the real way to solve unemployment is to finally reduce the work week to 4 days or 30-32 hrs as other countries have done. With the technology we have today, what used to take 2 weeks now only takes 2 hrs. So why are we still working 40 hrs a week? Then for every 4 jobs out there, one new one is created. Then there will be a overabundance of jobs. Now think about how many hrs a week our gov. official work. Their already on board with this idea for themselves, why not us?

Mr Mayrand, Are you saying that it is OK to have thousands of grid-connected, residential Solar PV systems that are not installed by professionals? I hope not. Even though solar PV electrical technology is quite simple it is not fool-proof and one fool can hurt a lot of people and cause a lot of damage.

You are correct that the unions, particularly IBEW, are training extensively for many types of renewable energy systems. They already install most of the nation's solar and wind systems based on KW capacity or dollar value. Utility scale projects will likely remain the predominant domain of union electricians or large open-shop contractors. Union contractors currently have a very small share of the residential market which would increase if large residential PV market finally opens up. Well-trained, professional craftspeople both union and non-union, will install the RE future. Renewable energy technician is not a skill set that stands apart from traditional craft skills.

Frankly, most American homes and lifestyles are not efficient enough to justify Solar PV.

Dennis, I am not talking 1000's of grid tie systems. I am talking 1000's of small residential systems that are not grid tied, or small solar powered stations that can be dedicated to a small area. Though these systems may not cover the total demand a home has, these small systems will reduce the load put on the grid and reduce a homeowners electric bill at the same time. Most of these type of systems are already installed by homeowners who have done their homework, so it may be possible to train and educate non professionals to assist in these type of installations. Then if everyone has some type of backup, and the grid is down for one reason or another, they will at least have some power to get by until the grid is up and running.
Or at least solar hot water for domestic hot water and heating with very little power.

agree that Solar PV should be distributed and off-grid where the value per kwhr is much higher. Matching a Solar PV DC source with a DC water pump is an easily scalable, high value application, particularly in third world countries. I completely agree with the basic ability and care exercised by a homeowner who "does their homework" as being satisfactory. I provide, as do many others, training sessions aimed at non-professionals to facilitate their projects. As an electrical inspector, I have seen a full range of quality or lack of; from contractors and homeowners alike. People who are going to live with their electrical work are usually careful to do it right.


Solar water heating should be on every American home roof and plumbed into its hot water system.
Solar PV? Perhaps not.

If we want solar PV to play a significant role in the nation's energy mix then thousands of Megawatt scale arrays must be built. Global installation of solar PV in 2007 was about 3.5 Gigawatt nameplate and produces the equivalent output in MwHrs as one typical nuclear power plant. Not trivial but not significant either. Manufactured panel output is rapidly increasing, expected to triple in 2009. Supply is expected to exceed demand for the first time; prices will drop. Even if the demand and financing are available, will there be enough installers ready in 12-18 months? Probably not.

Hypothetical example:
If it takes 2 experienced workers, 8 hours to completely install a 1 Kw solar PV system; and each worker costs exactly $20/hr;
then the labor cost/ Wp is 320/1000= $.32/watt
16,000 manhours needed for ( 1000 one KW) 1 Megawatt system

Can 8 people install 1000 rooftop systems in one year? Maybe? or not

If 8 workers can install 1 MWp in 8 weeks(I know they can) (2560 manhours); and each worker costs exactly $50/hr;
then labor cost/Wp is 128000/1000000= $.128/watt

Utility class PV installations are much less expensive to install than residential projects

Dear Dennis,

Agreed. Economies of scale will always mean larger centalised installations are cheaper than distributed (rooftop) systems IF the distribtion/network system costs are ignored. One needs to factor the capex/opex cost of installing large capacity (possibly long distance) high voltage distribution systems and the corresponding letdown/substation station costs. In addition you have to factor in the "in"efficiency or power loss that occurs in long distance power lines. I haven't seen a good, fully detailed cost comparison of large vs small PV power systems. However I wouldn't be surprised if neither the large PV power station or the individual rooftop option were the cheapest. I reckon it would be somewhere in between. Large enough to support a small community or a few hundred/thousand houses and hence have sufficient economy of scale, but small enough that it can be located close to (within a few miles or less) of the users to cut down the distribution, power loss and letdown costs.

Surely someone has produced a nice curve/data on this already??

Watt's Law states that power loss in a circuit is equal to the load in amperes times the resistance of the conductor in ohms. P = IsquaredR
The more current you push through the circuit, the higher the losses.
Conductor resistance is directly proportional to conductor temperature and length. Conductor temperature is directly proportional to load. Capacitive and inductive reactance are also important losses related to frequency. Lots of variables so simple charts may not be helpful. See "anti-islanding" studies for more information.

It is sometimes assumed that the flow of electrons in a conductor is at about the speed of light. There are other ways to understand electrical current but if this is true then a simple generalization is that an electron produced by my PV system will travel about 1500 miles in the first half cycle (120th of a second) and return to my inverter in the second half cycle. It does this 60 times per second. How do you tell where your electrons are used? If you use the grid for storage or backup then you share in the total distribution losses because you added to the current on the system.

It is often said that electricity takes the path of least resistance, this is not completely accurate in that it takes all available paths with the most current on the path of least resistance and less as the resistance increases. Only resistance matters for the DC part of the system but the AC part is affected by impedance which is a vector quantity of resistance and reactance.

Reduce your consumption to match your production, use DC directly and stay off-grid if you want to avoid transmission losses. The connected load in your home determines your system impedance. Transmission system impedance is made stable and controlled by capacitors and inductors.
