According to
this ABC report worldwide investment in renewables will achieve a record breaking $114b this year.
Despite this, participants in the ongoing UN climate conference in Bali are [depending on their representation]
calling for much more significant cuts and again here [science, environmental groups] or
taking a more cautions approach in consideration of economic and political fallout [trade ministers and other politicians]. The ABC alone is rife with articles from all perspectives.
Of local interest, New Zealand has already sided with the EU in calling for mandatory cuts of between 25 to 40% of 1990 emission levels by 2020. This call was echoed by non-politically affiliated Australian representatives at Bali, but pushed back by Crean and Rudd along with Canada, the USA and Japan.
But this is the beginning and hopefully just some initial posturing for future negotiations. The diversity of perspective and interest certainly justifies why the negotiations have commenced now for an agreement to take affect in a bit more than 4 years. They've certainly got their work cut out for them.
It would seem, again despite the investment sited above, the world needs something with a bigger punch to meet the emission cut targets while preserving economic security.
Nuclear power packs a wallop.
