Driving an Electric Car

Tuesday, August 10th, 2010
I was fortunate enough to test-drive the Nissan Leaf this week, and thought I would post some first impressions.

The car itself is very comfortable, and for anyone used to a Prius (or any automatic), it drives exactly like a normal car. The car is comfortable, acceleration is quite quick, and overall the car performs perfectly for city driving – my test drive was relatively short and was city based, but I am sure it would perform perfectly for mid-range journeys as well.

The range is stated to be 160km – certainly more than enough for the daily commute in a city. The car comes with Sat-Nav built in, and the available range is highlighted on the map. Obviously depending on how the car is driven, this range can change, but this is all reflected on the map  in real time so you can see clearly what affect different driving styles have on your range. The car also has an eco-drive mode which reduces the rate of acceleration and hence increases the range.

The manufacturers claim that the battery will be able to maintain an 80% charge after 5 years of usage, and 70% after 10 years. This would reduce the range to 128km and 112km respectively.

The car has several nice power management features – it can be set to only charge between certain hours, so you can arrive home, plug it in and it will only start charging during the hours that you choose. You can also set it to switch on the air conditioning at a set time as well, so the car can be heated up in the morning before you reach it – as this is done from the mains it will not reduce your range for the day. The car can also communicate via a smart phone app so all these features can be controlled remotely, allowing you to check if the car is charged from anywhere you have an internet connection.

The charge time is about 8 hours from a domestic charge point, and 25 minutes from a fast charge point. There are plans for 30 of these fast charge points around the country – for details of their locations, see the ESB’s PDF here.

Overall, first impressions were very good, and I can see electric cars becoming mainstream over the next decade.
I would have some reservations about having one as my primary car, due mainly to thinking if it would be possible drive from my home in Dublin to the family farm in Wexford after owning the car for 7-10 years without having to stop and recharge.

However, for any households who based in or near a city, and who currently have two cars, I can not think of any reason not to get one if you were replacing one of the gas-guzzlers anyway. The last census in 2006 indicated that of the 1,462,296 households in the state 1,173,519 (80.25% of total households)  had at least one car, and 609,270 had 2 or more cars (that’s 41.67% of total households, or 51.9% of households with a car) , so  there is a large potential market for electric vehicles.

The Leaf will be available in Ireland from February 2011, and will cost €29,995 after a government grant of €5,000. With running costs of approximately 1c/kilometre, anyone doing a significant amount of urban driving should seriously consider one, particularly if it was to replace a second car that was being upgraded anyway.

Lloyd’s of London on Peak Oil and Climate Change: Business as usual is no longer an option

Tuesday, June 15th, 2010

Lloyd’s of London recently published a white paper called “Sustainable Energy Security: Strategic risks and opportunities for business (PDF)“.

It would appear business as usual is no longer an option. The paper is available for free online and is essential reading.

The executive summary is worth quoting verbatim:

1.  BUSINESSES WHICH PREPARE FOR AND TAKE ADVANTAGE OF THE NEW ENERGY REALITY WILL PROSPER – FAILURE TO DO SO COULD BE CATASTROPHIC

Energy security and climate change concerns are unleashing a wave of policy initiatives and investments around the world that will fundamentally alter the way that we manage and use energy. Companies which are able to plan for and take advantage of this new energy reality will increase both their resilience and competitiveness. Failure to do so could lead to expensive and potentially catastrophic consequences. (more…)

Decreasing carbon emissions without affecting the quality of life

Tuesday, March 9th, 2010

There are a couple of simple ideas, which if implemented could make deep and long term cuts in our carbon emissions, while maintaining (or even increasing) the quality of life for all.

In no particular order, they are:

1. Immediately Implement a 4 day week (with obvious exceptions for emergency services etc.)

In 2008 Utah,spurred on initially by high gas prices and later by impacts from the global fiscal crisis, decided to do just this. One of the most conservative states in the US (approx. 60% of the population are Mormons) implemented one of the most radical solutions to the problems it faced – a mandatory 4 day week for 80% of state employees. Hours were changed from a 9-5 5 day week to an 8-6 4 day week.The results have been startling. (more…)

Now there’s an App to zap the sceptics

Wednesday, February 17th, 2010

The always useful site Skeptical Science, with its handy list of the most common arguments used by climate change sceptics and detailed rebuttals of them, is now available as an iPhone app.

So next time a discussion occurs and one of the old reliable arguments like ‘it’s the sun’ is trotted out, this app will give you the information needed to rebut the argument, and also allow you to report the arguments used, so skepticalscience.com can maintain an up-to-date list of the most common arguments being used by sceptics.

The highly regarded site is operated as a pro bono public information service by Australian physicist, John Cook.

The handy iPhone widget is available for free from the App Store or  www.skepticalscience.com.

15 Reasons to be (Mildly) Optimistic about COP15

Tuesday, December 8th, 2009

As the Copenhagen conference progresses, I thought it might be worthwhile to take a brief look what’s the various different countries have offered, and reasons why there is some room for optimism about a decent deal being done…

1. The US seems prepared to act, if necessary by bypassing Congress and the Senate. The formal declaration by the US EPA that CO2 (along with other greenhouse gases) is an ‘endangering pollutant‘ means that the EPA can now use it’s powers under the existing Clean Air Act to regulate CO2 as failure to act would “threaten the public health and welfare of the American people”.  It appears that if the Senate doesn’t pass the legislation currently before it the EPA will simply regulate greenhouse gases under existing laws instead. The current proposed cut from the US is approximately 17% by 2020 on 2005 levels. Although not ideal, this proposed cut is a dramatic improvement on earlier obstructionism from the US.

21st Century Swords to Plowshares: From Megatons to Megawatts

Saturday, November 28th, 2009

Currently, hydropower provides 6% of the USA’s electrical power, and solar, biomass, wind and geothermal combined provide 3%.

Dismantled nuclear weapons provide 10%.

The ‘Megatons to Megawatts’ programme was instituted in the 1990s as a means to secure the weapons that both the US and Russsia had agreed to dismantle as a result of arms reduction treaties. What was initially seen as a massive security issue has been transformed into a cheap and plentiful supply of fissile material, and also led to huge financial savings from not having to secure and maintain the warheads themselves, along with their associated delivery systems. The scheme has been very successful – material from Russia’s ex-weapons currently provides 45% of the fuel in US reactors, with former American weapons providing a further 5%. (more…)
