Does “Green” Sell?
By Claus Schafhalter | November 19, 2010
Activist organization Greenpeace publishes periodically a “Guide to greener electronics”. The guide attempts to rank top electronics manufacturers according to their “policies on toxic chemicals, recycling, and climate change”. I have written about this ranking earlier, it showed Nokia as the greenest company and Nintendo on the bottom of the list.
In October 2010 Greenpeace released their updated ranking, here are some excerpts for some companies including their “green score” (10 is best, 0 is worst).
1. Nokia (Score: 7.5)
2. Sony-Ericsson (6.9)
3. Philips (5.5)
4. Hewlett Packard (5.5)
5. Samsung (5.3)
…
16. Toshiba (4.3)
17. Microsoft (1.9)
18.Nintendo (1.8)
Looking at this list unscientifically I cannot see an obvious connection between sales success of a company and “greenness”. The top contenders do well in the markets, but the low ranked companies seem to do very well too. Microsoft is certainly making lots of money, Nintendo is my son’s favorite. So, is it fair to say that being green is an insignificant factor for overall sales success?
I think so. Availability of a favorite game or ability to play games with friends is important to many kids, sustainability is not. Does this change with the age of the consumer? Apparently not, features and coolness (think Apple’s product line) seem to be more important than qualities like energy efficiency or sustainable practices in production.
There might be exceptions to this observation. Some products sell because they are deemed to be green (think about a Prius Hybrid for a moment). Still, consumers might choose these products more to make a statement than for its green features.
But I do have one hope: What if there is a company that delivers cool and feature rich products made in a very green way? Will this combo sell?

Clean Tech In California
By Claus Schafhalter | October 7, 2010
- Roughly $11.6 billion venture capital have been invested into “Clean tech” since 2006, in the first half of 2010 California’s innovators received 40% of all venture investments for clean tech globally.
- California’ s manufacturing jobs shrank 9% between 1995 and 2008, however green manufacturing employment was up 19% during the same time frame.
- California’s electricity productivity outperforms the rest of the U.S., meaning California produces more with comparable less electricity input.

The 2000 Watt Society
By Claus Schafhalter | September 30, 2010
In 1998 researcher at the ETH Zurich released a vision of a society consuming only 2000 Watts around the clock (48 kWh a day). The Institute for Energy and Environmental Research (ifeu) released an interesting table comparing today’s energy usage in Germany to these targets.
| Area | Today | Target |
| Infrastructure | 600 Watt | 170 Watt |
| Consumption | 1780 Watt | 700 Watt |
| Housing | 1630 Watt | 440 Watt |
| Mobility | 1150 Watt | 450 Watt |
| Nutrition | 840 Watt | 330 Watt |
| Total | 6000 Watt | 2090 Watt |
I did not look up actual energy consumption numbers for the US, but it is save to say that we use much more energy per person in the U.S. than they use in Germany.
Now, if you look at the numbers in detail it becomes very clear that reducing energy consumption to the 2000 Watt level means significant changes to our live style. Say good bye to a single family home, a Hawaii vacation, and cities built into the dessert. So, I am not so sure if a 2000 Watt society can be accomplished.
But is the 2000 Watt target a reasonable objective?
I don’t think so. The problem we have is that we consume the wrong form of energy. Per definition, fossil fuels — the mainstay of our energy consumption — are limited and will be used up at a certain point in time. But let’s look at it from a different perspective:
The sun (our only real source of energy) radiates about 1.37 kW per square meter to the outer atmosphere of our earth. Looking at Germany, about 800 kWh reach the ground per square meter and year. If we also say that we use a solar cell with an efficiency of 15% the typical German could generate about 120 kWh per year and square meter. So, to generate usable electric energy each German would need about 440 square meter solar collectors to satisfy all his current energy needs (6000 Watts around the clock). That sounds a lot, but not out of reach.
The 2000 Watt target would reduce the necessary area to 146 square meters. So, that would make things easier.
However, once we add hydro power, wind, other renewables, and assume increases in energy efficiency of devices, homes and cars, the total shift to renewable is not out of the question using technologies that are available today!
So, what should the target be? Reducing our energy consumption or changing where we get our energy from? Well, it should be both, and we should start to switch now!

Energy And Power
By Claus Schafhalter | September 23, 2010
In an earlier post I was writing about electric cars and their batteries. I talked to a couple of people and I witnessed one seemingly wide spread confusion: What is “energy”, what is “power”, what does “Watt” stand for and how is this different to a “kilo Watt hour”.
Let me try to explain:
First, most of what I write today is based on the SI system (“Metric System”), with one (confusing?) exception.
But let’s start:
Energy:
Energy is the capacity of a physical system to perform work. Energy comes in different forms, i.e. mechanical energy, electrical energy (for instance stored in a battery), heat energy, and so on.
The SI unit of measure for energy is 1 Joule (1J).
1 Joule is the energy expended in applying a force of 1 Newton through a distance of 1 meter ( 1J = 1 Nm ).
Power:
In physics, power is the rate at which work is performed or energy is converted, i.e. energy per unit of time (second).
One Joule per second equals one Watt ( 1 J/s = 1 W)
And here is the confusion:
To describe power we often use Watt or kilo Watt (1000 W). A 100 Watt light bulb uses power of 100 Watts (100 Joules per second).
To understand how much energy we use in — say, 1 hour of using the light bulb, we just add the “hour” to our power: Energy used for our light bulb in one hour is 100 Wh (Watt hours), or 0.100 kWh (kilo Watt hours). As you can see, kWh is widely used, but regrettably not an SI unit of measure, and this is where I think a lot of confusion comes from.
So, the bottom line: If you use power of 1 kW (10 pieces of 100 W light bulbs turned on) for an hour, you just used energy of 1kWh (kilo Watt hours).
(The correct SI expression would be power of 1 kW for 3,600 seconds equals 3,600 kJ energy used).
Does this help?

When Disaster Hits Home
By Claus Schafhalter | September 16, 2010
On September 9 2010 a high pressure natural gas pipe ruptured and sent a fireball into the sky a few hundred meters away from my house in San Bruno, CA. At least 4 people died and many homes were damaged and destroyed. When I took my boys into the car and evacuated our house I saw black smoke coming our way. There was also an eerie orange glow behind the smoke. This was less than 15 minutes after the initial blast, and at this moment everyone thought that an airplane went down causing the fire. It was a reminder of the risks we incur using fossil fuels to drive our standard of living.
As I have written earlier I am critical continuing to use fossil fuels as the main source of our energy. But as a person used to the benefits of modern society I do also know that we cannot shift our energy production from fossil to renewables over night.
I am convinced that two things have to happen:
1. A long term shift to renewable energy sources accompanied by a much more efficient use of the energy produced.
2. A short term focus on safety to ensure that our current energy production and distribution system is as save as possible.
In 2010 we had a few wake up calls showing us that we need to rethink our behaviors, processes and methodologies. BP lost Billions of Dollars when their oil well in the Gulf of Mexico blew up. Comparably little money would have been necessary to prevent the accident from happening in the first place, if the risk and its consequences had been taken seriously.
Similar things can be said about the San Bruno gas explosion. It becomes more and more evident by the day that PG&E knew about the risk of these gas pipelines running through densely populated residential areas. But short term it is cheaper to take an elevated risk and hope that nothing happens. Mid and long term this is almost certainly the wrong decision, but if no bad incident happens just long enough then executives and shareholder can cash in on short term profits, while their successors will have to struggle with the consequences of unaddressed risks.
The day when the disaster hit home made me think. Why is it so difficult to change things before something happens? Why is it so seemingly easy to change things after something bad happened? At least four people died on that day in San Bruno. In the days and weeks after the explosion the Public Utility Commission, State and federal law makers come up with proposals to enhance inspections, replace old pipes, and enhance technologies meant to lower the risk of another blast.
What will need to happen that we take the risk of burning fossil fuels as the main source of our energy source more seriously? And will we be able to change before something really bad happens?
