My Emissions Exchange – Trade your personal energy savings as carbon credits

My Emmissions Exchange is a new market place that enables you to sell reductions you make in energy use as credits to people and organizations that are looking to offset their carbon footprint.  The service works by tracking your energy bills and calculating any reduction in energy use that you manage to make.  Savings that you do make can then be sold by My Emissions Exchange on your behalf or you also have the option of donating them to an organization of your choice.

The first thing to do when you sign up to the service is to set your baseline usage over the past 12 months.  You enter your energy data manually on the site but once you do this you must ‘lock it in’, after which it can only be changed by MyEex staff.  You will need to make copies of your energy bills and send them in to be verified.  The process isn’t entirely fluid, but the verification of carbon credits is extremely important.  False claims of carbon savings, e.g. when people tried to get paid for energy savings that would have happened anyway. This is the concept of additionality and is a challenge for all sellers of legitimate carbon credits.

Its also important that 12 months of data is used to create the baseline so that corrections can be made for seasonal variations.  In other words, if you live in a cold climate you can’t claim you have reduced your energy in the summer just because you are using less heating than during the winter.  In order to actually claim that an energy saving has been made, you need to demonstrate that your usage is lower in comparison to the same month from the previous year.

Much like the service EarthAid we recently reviewed, the next step is to go about reducing your energy usage.  The site provides some tips and resources to enable you to do this.  There is enough information to cover all the important basics which are where the most important savings can occur.  They are also categorized and contain estimates of the amount of energy/monetary savings you can expect from them, which can help you prioritize your actions.

If you manage to achieve savings over the comparable month from the previous year, then comes the payoff.  Once MyEEx verifies your savings they will certify and broker the trade.  And how much can users stand to gain?  Tami and Randy Wilson of Harrisburg, Pa received $17.50 for the metric ton of carbon dioxide that they saved, which would seem to compare reasonably favorably to market estimates.  A recent study from the Environmental Protection Agency suggested prices between $13 and $26 indicating there should be demand for carbon credits available on the MyEEx marketplace. Of course, users also stand to benefit from reduced energy bills.

My Emissions Exchange is a for profit company and currently take 20% commission on trades.  Project manager Paul Herrgesell believes the economic incentive is an important one, saying that MyEEx

“is a system that incentivizes you to save energy on a personal level and aligns with your economic interests”

Ensuring that energy savings are accurate and legitimate is a challenge that MyEEx will have to face.  Verifying actual energy bills seems like a reasonable way to do this, but is still potentially vulnerable to some types of fraud.  However, I don’t consider this to be in anyway insurmountable.  There are many industries which have to cope with an inability to extensively audit at such a granular level.  Instead, researching an appropriate quantifier is all that required.  For example, if you can verify that 1 credit in 100 is fraudulent, then the market price for credits on the MyEEx exchange would just be 99% of the price on the worldwide carbon market.

Challenges aside, My Emissions Exchange is a very exciting prospect with the potential to be an industry disruptor.  I’m really looking forward to seeing how the service develops and how the market at large reacts to what this company are doing.

Hands on with Google PowerMeter and AlertMe

Back since Google PowerMeter was first announced I had been excited to try it out.  Initially PowerMeter was only available from Utility providers that had partnered with Google.  Unfortunately the energy provider we use in our California office was not one of these and we started to consider switching just so that we could take PowerMeter for a spin.  Then Google announced that the PowerMeter service would become available to those who use select energy monitoring devices, the first being the TED 5000.  Great, I ordered one of these immediately, but too quickly to even read the small print which says that the TED 5000 will only work with 2-phase power supplies.  Inevitably, when I checked ours I found it is a 3-phase system and thus incompatible.  Of course, all of this only served to increase my anticipation.

So, when UK company AlertMe was announced as the second device partner, I finally got my chance to try out the elusive service.  AlertMe’s energy monitoring gadget is designed to monitor in real-time how much electricity you are using.  The system comes in two parts, the first being the ‘Meter Reader and Transmitter’.  This consists of a clip that attaches around your main electricity line.  Not an electrical connection though, it simply sits outside the wire’s shielding.  The clip is connected to a transmitter which will send the meter readings wirelessly to the second part of the system, the ‘Nano Hub’.  This gadget will receive these meter readings and via an ethernet cable will send your energy data over the web for you to access 24/7 from anywhere.

In addition to allowing you access to Google PowerMeter, AlertMe also provide their own dashboard to view your data, which is very functional.  Below you can see the initial snapshot view of whats going on.  You can see clearly your current electricity draw and a calculation of what it has cost you so far for the day.  Your personal cost per KWHr and currency is fully customizable.  The history feature is also quite detailed, you can view a graph of energy use for anywhere from one day to an entire year.  It can also be downloaded as a spreadsheet (csv).  Data is updated every 5 minutes so you can get a very detailed break down of your energy usage habits.  For example, you can clearly see peaks in the graph when your heating kicks in or when you put the kettle on for your morning cup of coffee.

Google PowerMeter – Tracking your energy usage.

Google Powermeter is a new software tool that has been developed to help people track and analyze their home energy usage. The tool will provide a graphical interface that shows, in real time, how much electricity your house is pulling in from the grid. The pictures Google have made public indicate that the software will help you identify how much of your total energy usage is being made by each individual component in your house. Using energy intensive utilities like dish washers and kettles will provide a characteristic spike in your electricity usage so you will be able to identify the electrical footprint of all the utilities in your house. Knowing Google, there will be a few unexpected extras thrown in there as well. It’s currently still in beta but it is slowly starting to become available to more and more people.

Example of Google Powermeter

So why is energy usage monitoring important? Studies have shown that the mere act of measuring energy will actually cause energy usage to drop by an average of 5-15%. This is presumably because many energy saving actions will become very obvious. If you can see in a simple visual format the effect of running a dish washer or dryer you will immediately realize its a good idea to only run them only when they are full.

Why is Google getting involved in this? Google understands that when it comes to the environment the stakes are high and has always set a good example of corporate social responsibility. If each household in America used PowerMeter and got a 10% saving in energy usage because of it that would be the equivalent of taking more than 17 million cars off the road. Not bad for a simple software tool that is relatively inexpensive and simple to implement. The savings for consumers are also huge. One Google engineer in the video below claims to have dropped his bill by 64% and saved almost $3,000 already.

This is exactly the philosophy behind the project. In order to change something you need to be able to measure it. Google is going to arm you with the information you need to understand your energy usage, therefore enabling you to make the most effective changes to reduce it. Google will provide many tips on what you can do to save energy (and money) and the collaboration between users will be very exciting: sharing energy saving actions; calculating how effective each action is based on feedback from many people’s PowerMeter results; detailed aggregate data of energy usage; are just a few ideas that come to mind.

At the moment Google is forging partnerships with utility companies to bring the service to the public. If you use any of these providers, then you should be able to test out PowerMeter right away. In the US the partners are JEA in Florida, TXU Energy in Texas and San Diego Gas & Electric. We are considering switching our provider in our California office to San Diego Gas & Electric in order to take advantage of this. This google map of utility providers that use ’smart grid’ technology is likely to be a good indication of the utility companies that will adopt PowerMeter in the future, as such technology is required to make it work.

Sam’s Household Energy Usage

Here is a real time graph of my household electricity use. I’m sharing this so that over the next few months I can share a few tips on trying to save energy around the home. I’ll be posting a guide on how I got this set-up. In the mean time, here are some interesting things I’ve noticed:

1. We seem to have a raft of appliances around the 2.4 kW mark. The kettle, cooker, dishwasher and dryer all seem to use about this much.
2. Our kitchen lights use a lot of power. 6 small spotlight bulbs managed to use just over 200W between them.
3. Lights use a surprising amount of energy! We have just moved into the house, and all the lightbulbs are the standard power-hungry filament bulbs. So as they all die hopefully we’ll be able to see energy reduce as we switch to energy efficient bulbs.

Use your up/down keys or mouse scroll to zoom in/out. The Home key takes you back maximum range. Double-click on a point to zoom in maximum.

A few things to note:
1. Although I am a full-time partner at PlentyWays.com, and our main office is in Laguna Hills CA, I am currently living in Dublin, Ireland. The wonders of the digital age! Therefore the machine I use to record my 230V house electricity usage is a monitor called CurrentCost. There are similar devices compatible for use in the US, some of which we will review on our site soon.
2. The house is a 2 story, 2 bedroom (+ box room) house about 700 sq ft in total. Just my fiancee and I manage to consume all this power.
3. Heating is gas, but cooker is electric. Shower runs off the gas heated water tank, dishwasher is cold feed. I’m looking around for some gas/water usage monitors and if I find any I’ll add that data too.
