Would you like to improve your knowledge of climate change? Have you ever wished you were better equipped to argue climate change at the dinner table – or when it was raised with friends, colleagues, clients, politicians? Here is the first in our series of ten tutorials on climate change.

The 2012 London Olympic Games made claims that it would be ‘the world’s first truly sustainable Olympic and Paralympic Games, leaving a legacy far beyond the departure of the Olympic Flame.’ So with a day to go before the opening ceremony, I thought I’d find out a bit more about what that means and whether these aspirations have been achieved.
If, like us, you are in NSW and were thinking of installing photovoltaic panels on your roof to generate your own solar electricity, there have been a few changes. The NSW Solar Bonus Scheme, introduced in 2009, provides gross feed-in-tariffs of 60 cents a kilowatt/hour for the solar electricity generated. This feed-in-tariff helps pay off the cost of installation. This scheme has been reviewed and from the end of October 2010 you will receive 20 cents a kilowatt/hour for electricity sold back to the grid.
Wind turbines have historically been limited to rural areas. However, this is about to change as vertical axis wind turbines are being introduced for residential areas. Vertical axis wind turbines look more like an egg whisk than a windmill, the main benefit being that they are unaffected by wind direction so are better suited for urban areas. Residential turbines can be installed on the roof or tower and feed energy into the building through an inverter. Urban Green Energy is about to introduce the vertical axis wind turbines into Australia to provide another renewable energy option for the home.
As Summer ends it is time to think about what you are going to do to keep warm this Winter. Our neighbour who is renovating, gave us a pile of waste hardwood, to burn in our slow combustion wood fire. This would otherwise have been destined for landfill. Fuel pellets take this concept a step further. Fuel pellets created from waste sawdust and other organic materials, burn with greater efficiency and lower emissions than wood, so we were keen to find out more.
Generating your own green electricity, decentralising power generation and removing reliance on power stations is another piece in the energy puzzle. You can now get hold of a green loan and generous government rebates to install photovoltaic panels using the abundant sunshine we enjoy in Australia. But what happens when the sun is not shining? There are a few options including generating electricity in your home from gas with new BlueGen fuel cells which are going to be available in Australia in the next few months. We have done the research for you.
Here’s a really interesting twist on people power. UK-based Pavegen Systems, have come up with a paving slab which can harvest the kinetic energy from pedestrian footsteps and convert it into electricity. The sustainable energy generated can be used for numerous activities including safety signs, lighting and even traffic lights.
