Just wanted to add the following image which compares the amount of tonnes of CO2 per hectare that is avoided in terms of crop usage and cover. This further puts emphasis that going down the biofuel route will get us nowhere in terms of emissions reductions.
In brief:
"...reforestation would sequester between two and nine times as much carbon over 30 years than would be saved by burning biofuels instead of gasoline."
"You get far more carbon sequestered by planting forests than you avoid emissions by producing biofuels on the same land"
Just have look and see what some researchers have been up to.
The have created a computerised race between five virtual dinouars, a human, an emu and an ostrich. Apart from the fun and curiosity, let me increase that awe to highlight the findings arising from this study:
In a recent post, Time to blog, I mentioned how I had the chance of going to Swansea, Wales for a 4-day planning workshop. I managed to secure a place and will fly off to Heathrow Airport on Sunday 2nd September. From there, the guys from the planningsummerschool will be there and take care of me for the rest of my stay in Wales.
Excellent.
I shall be coming back the following Saturday mid-afternoon. I shall go home change, grab my bag and drive to Gozo. Baanisuu and all our friends will be there. I shall stay there for I day.
In a few words, it transpires that growing biofuels is likely to have a worse effect on the environment than using fossil fuels. Here's and extract from the article posted on The Guardian:
Increasing production of biofuels to combat climate change will release between two and nine times more carbon gases over the next 30 years than fossil fuels...
Biofuel policy is rushing ahead without understanding the implications...
Reforesting the land would be a better way to reduce emissions...
As always we are looking to quick fix methods without realising the implications of such actions. Policymakers and world leaders should take note of such studies since they have set targets on switching to biofuels. So what should we do?
...the emphasis should be placed on increasing the efficiency of fossil fuel use and moving to carbon-free alternatives such as renewable energy...
Most of us would love to run our homes on solar power - if only it wasn't so unreliable, cumbersome and expensive. But thanks to a pioneering factory in Wales, those objections may not apply for much longer. Guardian Unlimited
