America's first new nuclear plants in more than a decade are costing billions more to build and sometimes taking longer to deliver than planned, problems that could chill the industry's hopes for a jumpstart to the nation's new nuclear age.

"Power generation from hydro, wind, solar and other renewable sources worldwide will exceed that from gas and be twice that from nuclear by 2016, the International Energy Agency (IEA) said today in its second annual Medium-Term Renewable Energy Market Report (MTRMR). According to the MTRMR, despite a difficult economic context, renewable power is expected to increase by 40% in the next five years. Renewables are now the fastest-growing power generation sector and will make up almost a quarter of the global power mix by 2018, up from an estimated 20% in 2011. The share of non-hydro sources such as wind, solar, bioenergy and geothermal in total power generation will double, reaching 8% by 2018, up from 4% in 2011 and just 2% in 2006."

"Following the Fukushima nuclear disaster, Japan is turning to renewable energy, and especially solar power, in a big way. By the end of 2012, Japan had already installed 7.4 gigawatts of solar power capacity, but that's set to double this year, according to analysts at Bloomberg New Energy Finance. This stellar pace of growth in solar power is set to make Japan the second-fastest growing solar market in the world, second only to neighboring China. It will also make the country the holder of the third-largest total installed solar capacity, behind Germany and Italy."

We already know that our traditional thermoelectric power sources, namely coal, are having a negative impact on our planet's climate. But, as it turns out, the reverse is also true - research has found that worldwide warming is reducing the amount of cooling water that can be used in coal and nuclear plants, and this is already causing problems for electrical grids in the US and Europe.

"There have been quite a few headlines lately about the record amounts of solar power getting built in China. In 2013, the country added at least 12 gigawatts of solar capacity - 50 percent more than any country has ever built in a single year. Impressive. But let's also put this in context. China is a massive country and is building lots of everything. And last year it added far more fossil-fuel output capability than it did solar, wind, hydro and nuclear power combined."

But how much can wind farms and solar panels contribute to a solution? Are they really the best option for Australia's energy future? And what part does the media play in the communication of all of this? The Science behind the headlines event (22 May 2012) held by RiAus attempted to answer these questions by combining a panel of scientists with experienced journalists - led by RiAus Programs Co-ordinator James Byrne. Each of the participants' knowledge of their specific field made for a varied and vibrant discussion that covered a wide range of topics. Is the public really aware of alternative energy options?
