Yet our capitalist system is based on the principle of economic growth - growth that is heavily dependent on fossil fuels and unsustainable practices. Just look at recent events; governments are terrified by anything that threatens economic growth – pouring billions of public money into failing financial systems. In addition, many economists see growth not only as desirable but as essential. They claim it lifts the poor out of poverty, feeding the world’s growing population, supporting the costs of rising public spending and stimulating investment and technological development.

The dilemma is how can we square Earth’s finite resources with the fact that as the economy grows, the amount of natural resources needed to sustain that activity must grow too. I am clear in my conviction that economic growth in its current form is unsustainable. We need a new paradigm that limits (or reduces) the global population, a meaningful shift away from fossil fuels to renewable energy, increasing energy efficiency and the adoption of more sustainable lifestyles. This will require courageous, co-ordinated and global government policies that ensure we don’t use up resources faster than the world can replace them.

Many will dismiss this as a utopian ideology. But isn’t it a utopian ideology to carry on blithely down a path that will ultimately lead to catastrophe? Yes, it will require a new world-view and radical changes but I think we have several grounds for optimism. Firstly, sustainable economies are more stable – whilst growth may be lower than in traditional economies it will be more durable in the longer-term and less volatile. Secondly, the shift towards a sustainable economy would create new opportunities, jobs and greater stability. Thirdly, the potential for conflict between nations is reduced as our dependency on fossil fuels reduces over time. Finally, there is a growing recognition (albeit begrudgingly) amongst governments that the current situation is unsustainable and the mood seems to be shifting from one of cynicism and self-interest to one of genuine commitment to tackling the problem.

The prospect of a truly sustainable global economy, fuelled by renewable energy sources coupled with a stabilised human population and harmonised with biodiversity is an ambitious yet achievable goal. But it’s a goal that requires a re-appraisal of the current meaning of economic growth.

The argument goes something like this; if we rely on fuel imports then we are forever at the mercy of foreign governments. If we re-open the coal mines we can become self-sufficient but our carbon emissions will start to increase. If we take the nuclear option then we are left with the legacy of dangerous radioactive waste. The argument usually then goes on to claim that renewables are well-intentioned but will never provide enough energy to meet all our needs.

There is some truth in this latter point but only if we continue with our current high levels of energy consumption and gross inefficiency. A determined and courageous policy of large-scale investment in renewables coupled with energy-efficiency measures (e.g. legislation to compel manufacturers to remove stand-by buttons from appliances, banning patio heaters and standard light bulbs, etc…) could lead us to a truly sustainable future. It is a vision but an achievable vision.

Living near to a wind farm set in a nature park, we often walk past the windmills. In the seven years that we have been walking this route, we have never seen a dead bird. The noise is a low swirling and humming, which is barely audible.

There is an aesthetic beauty about them too. Not only in appearance but also conceptually in the way they convert a free resource into useful energy, without producing pollution or causing global warming.

How can this be unsightly when compared to chimneys belching out smoke, traffic jams and smogs? And what about the oil that is imported from corrupt regimes, Middle East wars and climate wreaking emissions from what is ultimately a limited and increasingly scarce resource?

We don’t understand this at all.

When I think of dynamo torches I think of big clumsy things, that need continual winding. This torch is the opposite of this . With a new generation 0.5W LED, one minute of winding gives you 20 minutes of light.

Sturdy, and slightly smaller than an average size mobile phone. The torch has 2 light intensities and also a strobe light. The robust dynamo gear tucks neatly behind the torch, preventing it getting in the way.

This is the brightest single bulb LED torch I’ve found to date. Apart from the obvious benefits like never having to buy batteries,or getting cut short in a situation with battery fade, the solid construction of this torch will make it suitable for a wide range of uses: general household use; camping or more extreme uses. (Battery life diminishes quickly in extremely cold environments - no battery, no more problems?).

This torch was perfect at Glastonbury Festival and I have every faith in it for my Arctic Survival Challenge for WaterAid in February 2006.

The Puma Dynamo Wind-up LED torch is available from Ecoutlet.co.uk and other good on-line shops.

I had one of these given to me as a present. They are rather fun, and it has provided an unobtrusive light on a few night time fishing trips over the last few months. Over the summer I have plans to take it camping. I think it’s waterproofness will be perfect for the British summer.

To be honest, while the Sun Jar is a fun gadget it doesn’t give off enough light to be anything, other than an ambient light. But what’s wrong with that, after all that is what a tea light does, and it does give off 5 hours of light from a full charge.

Sun Jars are available in a number of countries including the USA and UK and come in 3 different light colours, blue, orange and white.  Try searching for ‘Sun Jar’ using your favourite search engine.

Summary: A solar gadget which makes a good eco talking point, but could be improved if the manufacturers used recycled glass.

The first thing and best thing is to upgrade your memory. Before buying new memory check what kind of memory is in your computer/laptop so you don’t buy the wrong memory and also check your computers manual to see what the maximum size of memory your computer can handle. If you are unsure what memory you need try asking a someone that knows about computers or try a local computer shop. There are many places you can buy memory from places like local dealers to hundreds of online places like tigerdirect and newegg or E-bay.

Next you should get the latest patches, drivers, security updates from Microsoft or if you own a mac make sure that you run software update. Also make sure that you download other drivers that were not downloaded by Microsoft or Macintosh that you may need which can be downloaded directly from the manufactures web page. Next you should remove programs that you rarely use or never use by accessing add/remove programs by going to Start>Control Panel>Add or Remove Programs and also you should remove any unwanted files that are taking up unnecessary space. Next thing after downloading updates and removing unwanted items is to defrag your computer. If you have never defraged your computer in a long time it could take a few hours depending on your system and hard drive size. To accessing Defrag click Start>Programs>Accessories>System Tools>Disk Defragmenter and choose the drive you want to defrag.

Next monitor should have the brightness on your monitor turned down all the way or down enough so you can still read what is on your monitor. If you are still using a CRT monitor you should go out and buy a Energy Star flat panel monitor and properly dispose of your CRT monitor at a nearby recycling program that takes CRT monitors (some places will take your CRT monitor for a small fee).

Also make sure that your computer is plugged into a outlet strip and make sure that you turn off the switch when not using the computer and turn it on when you do use your computer (Your computer still uses power when not turned on). Lastly if you use window 2000, XP or Vista your computer should be able to use hibernation. Hibernation makes your start up time drop dramatically and extends the hard drive life span. For more information on how to configure this XP users, Win 2000 users. For windows vista it should be already enabled by default (I’m unsure about hibernation in vista since I have never used vista).

1. It takes 30 years to get your money back. Of course it depends where you live, what type of system you have and how much energy you use. Here in California, 6-8 years is more the norm. Plus, don’t think of it as getting your money back, think of it as an upfront cost that then provides you something for free.

2. If there’s a main power cut in your street, you will still have electricity. No, this isn’t normally correct, almost all systems are “grid-tie” systems. This means you receive power from the national grid as normal, and your solar panels send any electricity generated to this grid, essentially using the grid as a battery. If there’s a power cut then you will not be able to receive any power from the grid or your solar installation.

3. The electricity company will pay you for any extra energy you produce. This isn’t usually true. Your solar installation will, at times, be generating more electricity than you are using so your electricity meter will start going backwards. Over a 12 month period, if you have generated more electricity than you have used, you will NOT get any money for this, therefore it is very important to size the system you have to the amount of electricity that you use. Else you will be paying to build a bigger system than you can benefit from.

4. The government will give you massive rebates. Once again this depends on where you live and what current rebate program is in effect. It’s not uncommon to get 50% or more back in rebates and tax credits, however you should investigate this and apply before you order anything. It’s usually calculated on a per watt basis.

5. My condo owner or Home Owners Association won’t allow it. In California it’s against the law to restrict the installation of solar panels. They can make demands on how it looks, position etc, but nothing that will add more than 15% to the cost. It’s likely to be similar wherever you live - the government want you to pay to create your own energy!

6. It’s difficult to install, and looks ugly. No, it’s actually relatively quick and simple (less than a week depending on the size), but there are hundreds of companies that are licensed and will do it for you. As to whether it looks ugly, well, that’s in the eye of the beholder!

In a recent research published by the Energy Saving Trust they’ve calculated that if one mobile phone charger per household in the UK is left on standby, the energy wasted is enough to provide the electricity needs of 66,000 homes for one year.

Those of you with a plasma TVs, take notice…
