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.

Top 5 Green & Environmental iPhone Apps

These days you can’t go anywhere without stumbling over someone who’s attention is deeply invested in their beloved iPhone.  I’ve managed to avoid this trend so far (I’m an android), but I’ve managed to test out a number of green and environmental iPhone apps on my old iPod touch.  Whether the ubiquity of these gadgets and gizmos is a positive for the environment is a debate we will save for a rainy day.  There’s no doubt that a lot of additional electronic waste is produced, but there are undoubtedly situations where these items can be helpful, e.g. cutting down on travel needs or being used as an alternative to newspapers.  With out further ado, let’s get to it:

CFL Light Bulb Savings Calculator

iphone-1-doneThe CFL Savings calculator is a very simple app that will allow you to calculate just how much money you can save by switching energy intensive incandescent bulbs for CFL ones.  CFL bulbs represent a far more energy and money sensitive option over traditional incandescent bulbs.  Choose how many bulbs you have and your location, which it uses to provide the cost per kWHr and it will calculate your savings.  You can also enter the cost of each bulb and the amount of hours per day you use them.  The app is great as it makes it clear what a no brainer it is to switch to CFL bulbs.

  • Price: $1.99
  • Free Version Available?: No

3rd Whale’s FindGreen

iphone-2-doneFindGreen has been described as Yelp for the environment.  Quite simply it is a guide-book to all the great environmental and sustainable resources that surround you.  The app auto locates you using GPS and with 60,000 listings makes it a breeze to find anything from yoga studios to bicycle shops or organic restaurants in your vicinity.  Features include the ability to submit new listings and rate existing ones.  The ‘green tip of the day’ function is also a very nice touch.

  • Price: FREE
  • Free Version Available?: Yes

A Real Tree

iphone-3-doneThe name really says it all for this incredibly straight forward iPhone app.  Quite simply, when you purchase this app for $0.99, one tree will be planted in the real world.  The tree will be planted in one of 12 countries that are currently fighting deforestation.  All of these countries are located in tropical regions where the climate benefits from tree planting are maximized.  When you purchase a real tree, or one for a friend, the app will furnish you with a ‘virtual’ tree (as pictured) which you can display proudly on your Facebook page.

  • Price: $0.99
  • Free Version Available?: Nope, just buy the tree!

Amazon Kindle for iPhone

iphone-4-doneAnother simple, but effective app.  This app from Amazon allows you to read the books you have purchased for your Kindle, Amazon’s popular eBook reader.  Whilst the small size of the iPhone doesn’t really provide an optimal interface for reading it can be useful for reading a few pages on the go.  The app will sync the page that you are on with your Kindle, so it is easy to pick up just where you left off.  eBooks are set to have a big future in reducing the amount of paper we use and tools like these are important for making that transition.

  • Price: FREE
  • Free Version Available?: Yes

Clear Standards Carbon Tracker

iphone-5-doneThe idea behind this carbon tracker is that it will use the iPhone’s in-built GPS system to track your movements and use this to calculate your carbon footprint.  The limitation here with the iPhone is that you cannot run applications in the background, so you will have to have this app open, or there will be a fair amount of data to enter manually.  If you can get over this hurdle, it’s a great tool to help you reduce your carbon emissions.  It allows you to set monthly goals and motivates you to keep them each time you open the app.

How I created my home energy monitor

My power use

The target

First things first – I’m in Ireland. The UK/Irish power system of 220V meant I had to go for a compatible power monitor. So I was out of luck with all the energy monitors I’d been reading about for the USA (T.E.D. The Energy Detective, Cent-a-meter, Blueline etc). I settled on the CurrentCost in the end, because it had a great community of people developing software.

So I bought a CurrentCost off the manufacturer’s ebay store, along with a serial to USB data cable I’d use to grab the data.

Setting up the CurrentCost is remarkably simple. Just plug the device in, attach the sensor to your electricity supply and you are done. Couldn’t be easier!

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.

Top Ten Electric Vehicles on the market

Electric cars are a very promising technology in reducing the carbon footprint of transport.  Although we are likely to see much innovation in this field in the future, many people do not realize that the technology to produce cars that run on electricity is already here.  Electric cars in general produce far less emissions than the best fossil fuel cars on the market.  Furthermore, if your electricity supplier uses renewable energy sources, the emissions of your electric car will effectively be zero.  So with out further ado, lets take a look at the top electric vehicles which are available now, or will very shortly be in production.

REVA G-Whiz i

REVA G-WhizThe REVA G-Whiz is currently the most popular batter powered electric car in the world.  Manufactured in India, the REVA is a smart 3-door city car that will fit two adults in the front and two children in the back.  A full charge will take around 6 hours and will cost less than $1.50 meaning running costs are an astounding 2c per mile.  The newest version includes higher performing Lithium Ion batteries that extend the range to 75 miles.

  • Range: Up to 75 miles
  • Max Speed: 50 mph
  • Approx: $13,000

Th!nk City

th!nk cityThe Th!nk City is another 3-Door Electric vehicle running on sodium or lithium batteries.  A product of Norwegian firm Th!nk, the City car is available in Norway and European markets with plans to come to the US soon.  It is one of only two crash tested and highway certified fully electric vehicles.  (The Tesla Roadster is the other).  The car is designed so that it can be recycled after it has been decommissioned helping to further reduce its environmental impact.

  • Range: Up to 110 miles
  • Max Speed: 62 mph
  • Price: NOR 212,500 (US $34,000), but US target price is $10-15,000

Smart ED

smart-edAvailable next year, the Smart ED is the first all electric vehicle from SMART, manufacturers of the pocket sized city cars that are ever more popular in Europe, and – believe me – they look even smaller in real life.  The ED follows much the same design as other Smart vehicles, but behind the fuel cap is actually a standard mains plug.  The Smart ED can fit only 2 passengers and will take around 8 hours to charge the batteries to capacity.

  • Range: Up to 68 miles
  • Max Speed: 74 mph
  • Price: Approx < $20,000

Tesla Roadster

tesla roadsterThe Tesla Roadster is without doubt the cream of the crop of electric vehicles. With a stunning design and performance to rival some of the best fossil fuel powered sports cars, the Roadster is truly a break through vehicle that demonstrates that you don’t have to make cutbacks on quality if you want to go electric. It combines a 0-60 mph time of 3.7 seconds, with an efficiency that is up their with the best electric vehicles – achieving a breathtaking 120 miles per gallon equivalent (mpgge). The only drawback would be the over $100k price tag, however the Silicon Valley company behind the Roadster is planning a more accessible sedan version known as the ‘Model S’, which will cut the price in half.

  • Range: 244 miles
  • Max Speed: 125 mph (electronically limited)
  • Price: $109,000

Toyota Prius (Hybrid)

priusWhilst not technically a fully electric vehicle, the Toyota Prius with its hybrid engine deserves a mention here.  The greenest vehicle by the world’s largest automaker is an important milestone and a very advanced specimen of technology.  The hybrid engine means the car will run on fuel but will also use advanced techniques such as regenerative breaking (which captures a vehicles kinetic energy whilst breaking) to charge an onboard battery.  When the battery has sufficient power stored up, the engine can switch to EV mode, whereby it is propelled purely by electrical energy.  This hybrid engine results in 54.7 mpg rating, although the 3rd generation models will bring this up to 60.3 mpg.  Its no surprise to learn that worldwide sales of the Prius reached 1.2 million in early 2009.

  • Range: ~ 600 miles (Petrol)
  • Max Speed: 112 mph
  • Price: $21,000

Lightening GT

lightningThe Lightening GT is in a similar mould to the Tesla Roadster. The British made Lightening features a sleek design and a 0-60 mph time of under 4 seconds. A killer feature is its fast charging lithium-titanate battery which, given the right high capacity power source, can charge in 10 minutes. On standard mains power this would be more like overnight. The lightning GT is a 2 seat convertible and is available to order now for 2009/2010 delivery in the UK and is set to reach the US market ’soon’.

  • Range: 188 miles
  • Max Speed: 130 mph (electronically limited)
  • Price: £120,000 / ~$200,000

Mitsubishi iMIEV

imievThe iMIEV from Mitsubishi Motors Company is due to start production in 2010. It can fit four full sized adults but has a greater efficiency than the G-Whiz, getting around 100 miles from 16 KWh and has an impressive top speed of around 80 mph.

NICE Mega City

nice-mega-cityThe Mega City available from NICE (No Internal Combustion Engine) is a french made 2-seater city car.  NICE also have a large truck version, the “Mega Mutitruck” and a pickup style version, the “Mega Worker”.

  • Range: 60 miles
  • Max Speed: 40mph
  • Price: ~$20,000

Vectrix Scooter

vectrixThe Vectrix was the first high powered electric scooter available on the market. Its great design and 0-50 mph in 7 seconds made it very desirable. The company unfortunately went in to liquidation earlier this month and won’t be able to continue existing in its current form. However, Vextrix scooters are still readily available second hand and the technology could be given further life if a suitable company swoops in to buy the remaining assets.

  • Range: 65 miles
  • Max Speed: 60 mph
  • Price: ~$9,000

Oxygen Cargo Scooter

cargo-scooterThe Cargo Scooter is a Dutch Made Electric Scooter that has been picked up by Domino’s Pizza to equip their fleet of delivery vehicles.  Taking only 2-3 hours to charge, it is adept for traversing short distances quickly, cheaply and environmentally.  It is available now in both European and North American markets.

  • Range: 50 miles
  • Max Speed: 28 mph

Clearly there are very good options for fully electric vehicles on the market right now and even more in the near future.  It is exciting to think that the technology is still in its infancy and there are further gains and innovations to be had.  There are many advantages to driving electric cars over their combustion engine equivalents.  No more trips down to the pumps, electric cars all work off standard mains electricity that we have at home.  No more remembering to check the oil level in the engine, electric cars don’t require the stuff.  No more shouting over the sound of the engine, electrical engines are near silent.  Some even worry that this may be a safety hazard as people can’t hear the cars coming down the road.  It would be trivial however to add an artificial sound and it would surely be engineered to remain as quiet as possible to those within the vehicle.  Also bear in mind the running cost of an electric vehicle is far less than a petrol/diesel powered vehicle.  Take a look at the following calculation for a demonstration.  Note that it does not include various subsidies and reliefs that you can get for driving an environmentally friendly vehicle, which are only likely to increase further in the future.

The average American vehicle does 20 miles per gallon.  At $2.80 a gallon, this is around $0.14 per mile.  As noted above, the G-Whiz costs around $0.02 per mile.  The average American drives around 12,000 miles per year, which will cost $1,680 in your gas guzzler, or around $240 in your G-Whiz, giving a massive saving of $1,440 a year.  The car will pay for itself in no time.

Now imagine a more extreme case: You drive a gas guzzler that manages 13 mpg, fuel hits $4 a gallon again and you drive an amount towards the upper limit of the US Average (say 15,000 miles per year).  In this scenario your car costs around $4,615 a year to run, compared with the same $240 for your G-Whiz!  A truly amazing difference.

Update: Just stumbled across ZapWorld as well, who seem to do a range of electric vehicles. If anyone has any knowledge of them let us know in the comments.
