Are the 50/50 by 2020 targets achievable, or are they a toothless tiger?

From time to time the question of targets comes up – should we set any, are they achievable, are they even necessary?

Today 98% of the world’s climate change scientists, Australia’s CSIRO, the British Royal Society, President Bush, Prime Minister Howard and even Mr Rupert Murdoch have come to the view that man-made carbon dioxide (CO2) emissions are contributing to significant and potentially devastating global warming. Something must be, and can be, done.

From my point of view, we need to be setting the sort of targets that will save the planet, and do whatever it takes to meet them. This is where the 50/50 by 2020 target comes from – a 50% reduction in energy use, and 50% of what we do use from renewable sources by the year 2020. Without a doubt, it will cost money to achieve the targets but, on the other side of the coin, meeting the target will allow us as a community to tap into enormous opportunity. Don't forget that unmitigated climate change will bear a huge cost to us all.

There are many things we can do as individuals that make a difference. Some of them cost money and effort, many of them don't. Here are some examples.

NOW (the next 60 minutes)

∑ Put a 50/50 by 2020 bumper sticker on your car and, when you get home, put one on your second car. This demonstrates that you are a part of the community that is willing to tackle climate change and endorse 50/50 by 2020. If you want a bumper sticker, give me a call. If you want a stack of them, I'll send them to you.
∑ Make sure your tyres are pumped up on the way home, this will save you fuel. Drive a bit slower this will save you even more fuel.
∑ When you get home change your electricity over to 100% Green Power which will send a message to government and industry that you are willing to support a clean energy future. Enjoy opening your next electricity bill, turn it over and see that you produced no CO2 from your electricity use.
∑ Make sure you turn off lights you do not need and switch off all stand by appliances at the power point. Have a shorter shower and use cold water for that load of washing.
∑ These simple things will reduce your carbon footprint by several tonnes a year. Tell someone what you have just done.

THIS WEEK

∑ Ring a business that provides you with free compact fluorescent lights and water saving devices. These guys will come to your home and install them for free! You will use less water and hardly notice the change, and you will use up to 80% less electrical energy in your lighting. This simple step will save you money for the cost of a phone call.
∑ Hang out the washing, reduce the use of your clothes dryer if you have one.
∑ Make sure that the dishwasher is full before you set it running.
∑ Only boil the water you are going to use, one cup of water for one coffee. Using gas to boil water produces a fraction of the CO2 that an electric kettle does. Put the lid on the saucepan and save all that heat energy from escaping.
∑ Recycle all you can.
∑ Buy locally produced foods, which will save on the energy embedded in transport and distribution, as well as supporting local employment. Don't buy strawberries grown in California. Buy food that has less packaging. Food is responsible for 30% of a household’s energy consumption. Use re-useable shopping bags.
∑ Drive less, walk more, take a bus or ride your bike. Save energy and money - and feel fitter.
∑ Support businesses that are actively engaged in reducing your and their energy consumption, and rise to the challenge of climate change.
∑ Turn off that beer fridge you almost never use.
∑ Look into buying carbon offsets to reduce your own carbon footprint. You can purchase these and cancel out the CO2 emissions you cause when driving the car or flying. If you are organising an event such as a concert or school sports day, see if you can make it carbon neutral by including credits in the ticket price. The money is used to reduce CO2 emissions through efficiency programs, carbon sequestration and renewable energy projects.
∑ Put a jumper on instead of using the heater.

THIS YEAR

∑ Set in place a long term plan to replace appliances, when they pass their use-by date, with the most energy and water efficient ones on the market.
∑ Check your electricity bills and see that your carbon debt is shrinking.
∑ Plan to Insulate roof, floor and walls which will reduce heating and cooling energy bills. This will save money.
∑ Solar Hot Water can cut your energy use by 30%, and good rebates are available
∑ Install Solar photovoltaic (PV) cells, generate your own electrical power, and qualify for rebates of up to $8,000 for domestic and $12,000 for community groups. Invest in renewable generation. After investing in solar panels for my rooftop, my quarterly electricity bill is in CREDIT.
∑ Installing skylights in those dark rooms and hallways will save energy in the long term
∑ Use Curtains and Blinds with pelmets to save on heating and cooling.
∑ Install Water tank(s) to collect that precious rain water
∑ Plant deciduous shade trees that protect your home from the summer heat and lose their leaves in the winter to allow the winter sun to warm your home.
∑ Vote for a political party that offers a comprehensive strategy on climate change and demonstrates their commitment on acting on climate change.
∑ Buy a smaller more efficient car, use E10 petrol, buy a hybrid vehicle, get a bus pass, check out if a moped or electric scooter would suit your needs, ride a bike and keep fit as well, walk.
∑ Grow your own veges and fruit at home or in a community garden.
∑ Join a climate change organization or Landcare. Talk about it with your friends, write to your political representatives, start a group, join Clean Energy for Eternity.
∑ Use energy efficient design if you are renovating your home. Employ a Green Architect and save energy dollars for the long term. Use low energy materials. Build an energy efficient home and save long term on the running costs.

If most of us did a few of these things, we would be well on the way towards a 50% reduction in the consumption of energy. What about a 50% production of energy from renewable sources? That is more difficult for an unfunded community campaign. Difficult doesn't mean impossible.

Clean Energy For Eternity has had discussions with three renewable energy companies that want to bring their business to our region. They want to come to us because of our targets. We are putting our hand up to say we want to be proactive in dealing with climate change. Exciting prospects include a solar farm, funded by community investment. 30 acres of solar photovoltaic cells could provide 2 megawatts of power, and would be a tourist attraction. A French bioenergy company wants to set up in Australia, and they are looking to start with a pilot project in our region. They feel that our targets can be easily achieved. A wind company wants to start some wind monitoring in our region to determine whether or not a community owned wind farm would be feasible.

Business is coming to us, but making the much-needed change through community investment alone is going to be hard yards. What we would love is some government assistance in reaching our targets, and we will be talking to all candidates before the election about what they can offer us.

There is no simple single solution to climate change. Luckily there are a range of renewable technologies that can contribute rapidly to reducing our global greenhouse emissions. The examples given below are not comprehensive. Every effort counts.

Solar - world-class research at the Australian National University developed "sliver cells" capable of massively increasing the effectiveness of photovoltaic panels.

Wind - projections suggest that wind could rapidly provide a significant proportion of Australia's electricity.  Community-owned windfarms dispel myths and overcome many perceived  problems. The Australian Wind Energy Association has compiled recent international quotes on wind energy and global climate change.

Geothermal - Australia has some of the world's best hot dry rock resources and the technology to provide geothermal baseload electricity in many regions. The Centre for International Economics reviewed Australia's geothermal potential in Sept 2006.

Biomass is any kind of organic matter produced by plants and animals. Biomass energy systems convert this matter to fuel for energy. NSW biomass energy industry is researching the production of energy from: methane gas (eg, landfills and sewage treatment plants); wet wastes (eg, abattoirs, feedlots and food processing); dry agricultural byproducts (eg, sugar cane waste); municipal mixed wastes (eg, household garbage and prunings); forestry byproducts (eg, sawmills and forestry operations).
