Even under a conservative government, coal-fired electricity has no future and the power of public opinion will force rapid, effective action on climate change, writes Mark Diesendorf.
The Australian Energy Market Operator's determination that 100 per cent renewable energy is feasible carries a hefty credibility, writes Jenny Riesz.
The Renewable Energy Target does a good job supporting wind power, but other agencies are needed to get a diversity of renewables, writes Jenny Riesz.
Australian Energy Market Operator's 100% renewables modelling has been criticised for not putting the figures into context. When done so, the 2050 renewable scenarios are similar in cost to most alternatives, writes Jenny Riesz.
It's an old myth that renewable energy is unreliable in supplying base-load demand, or that it is unaffordable. All we need are effective policies to drive the transition, writes Mark Diesendorf.
A carbon price of between $50 and $100 per tonne would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.
State and local governments have a duty to complement federal climate policy, as they not only have the power but the best knowledge of the field, argues Martin C. Jones.
Australians may be cutting back carbon-intensive activities, but until the government is more transparent about emission cuts there’s no way to check, writes Sarah Waddell.
Australia must stop backing every renewable energy option and make a public choice to back the one with the best prospects, write Elizabeth Thurbon and John Mathews.
