Ooops… sorry there mate. I thought so at first, but then the “joke” just kept on going....
OK, now for the other questions asked tonight.
Hi Shane,
I don’t get the jump to overpopulation. isn’t over consumption?
We could really oversimplify it and draw up a rough equation that looks something like this.
Earth’s finite resources / population = lifestyle.
So… if you want to fit more and more people on planet earth, and maybe switch to a vegan lifestyle, go for it!? But… someone will have to inform all those extra “consumers” that there isn’t as much to consume.
At some point we’ll have to figure out exactly what the long term sustainable carrying capacity of our civilisation is. It’s an ever shifting equation that changes as technology improves our chances, while environmental problems become more and more serious.
Just keep in mind 1.3 billion Chinese peasant farmers can do just as much environmental damage as 300 million first world American consumers.
also got me thinking about the cost of changing current practice
just wondering how we might prepare for the peak apocalpyse - do you have a recommendation for a car to buy (if any)?
50% of the energy a car ever uses is consumed by the time it is in the car-yard just in making the thing, so I’m not really into cars. I have one, but we are gradually making life changes such as where we send our kids to school etc so that we can live less car dependent lives. So I’m with the Australian peak oil Senate inquiry into this one, that basically concluded a “bit of everything” — including drastically rezoning our cities and upgrading public transport so more of us can walk and cycle and train and tram to work.
I was using E10 fuel - is it worth it - or is there a biodeisel option that is better- what cars does this work for?
It depends on the source of the bio-fuel. If it’s ethanol / bio-diesel at the expense of food, there are serious ethical concerns with that as Andrew Cameron pointed out in his peak oil article.
and in terms of wind farming and solar stuff - how practical would this be for the averge home or is it a lobby governemnt thing or both?
Absolutely both. The future of transport and energy is a diverse and decentralized renewable electric grid. Diverse means you can sell any excess solar power back into the grid, along with some neighbour that might even have a home scaled wind turbine… all feeding into the grid. Both large and small providers, wind, solar, biomass (not crop but crop residue / agriwaste) can all feed into the grid, backing it up from multiple directions. Imagine your suburb all gathering together and building their own local power sources? You can become a part owner in your own local power grid… if NSW legislation changes. It’s happened in Germany and there’s no reason it can’t happen here.
Did you know NSW coal runs out in 33 years? We’ve got to go renewable not just for global warming’s sake, but because we are running out of this stuff!
any dollar estimates on what it would cost me to make some lifestyle adjustments beside token worm farming, getting rid of the plasma and cloth nappies for the kids?
There are tons of little things you can learn to do. If you’re really interested, subscribe to a Greenie tips sort of magazine.
We recently put solar thermal hot water on, and I think the rebate on that is even bigger now. It cost us over $3000 and works really well in summer, pretty well most of the year. Should get the money back in 5 to 7 years through saved electricity, and then the rest is free for the rest of it’s 20 to 25 year lifespan… until the tank needs replacing. It reduces our electricity consumption for heating water, which can be about 1/3 of a home’s electricity use. It’s FAR cheaper that way than rigging up a solar PV system to capture electricity and then convert that to heating water. No way! Just use the sun’s heat directly.
For conscience sake we went with 100% green electricity with Energy Australia, which means our “fraction” of electricity use HAS to by law come from renewable energy somewhere. It costs us about $400 a year extra. I can’t be a greenie activist and refuse that hey? We run a business from home, and so are POWER HOGS! So to be a greenie power hog, I just have to pay for it.
However, I understand in the next 5 years all sorts of amazing cheap solar PV will be hitting the market, and then I’ll probably buy up big (God willing). But even then I’ll still use Energy Australia for the night. Decentralised and diverse mix of power sources and use.
The reality is that our electrons are probably a mix of coal and renewable — whatever’s on the grid. But the money I pay for electricity funds a wind turbine or something somewhere. Not sure what they’d do if EVERYONE suddenly switched to 100% green electricity, and how fast they could implement it, but there are some remarkable new 24 hour baseload renewable energy schemes. Solar thermal with heat storage for overnight, CETO wave power, solar chimney’s, geothermal and huge wind farms up and down the coast of Australia can all pretty much well function as a coal fired power station. Of course, in combination these are unbeatable. If renewables received as many subsidies as oil and coal, we’d be well under way weaning off the foul fossils.
However, despite Andrew Cameron’s great work on Global Warming and Peak Oil, I haven’t seen any serious papers addressing what to do about overpopulation from a Christian perspective. Byron Smith’s cool peak oil article was the closest thing I’ve seen approaching population, but didn’t quite end up covering that topic.
