newables expert, says the sector needed less and less in government subsidies as costs come down. Over the last five years, the price of solar energy dropped by 80%, while wind power’s costs dropped by a third overall. Varro says that offshore wind power – traditionally seen as expensive – was becoming more price-competitive as turbine sizes increase and more efficient construction methods are used. Low interest rates were also encouraging more investment in renewables. Nuclear energy is seen by some as an important ingredient in tackling climatechanging carbon emissions. “Fossil fuels continue to dominate energy supply, but the composition of investment flows points to a reordering of the system” The IEA says the drop in the price of renewables has not been reflected in the nuclear sector – rather, the reverse. And there are continuing worries about nuclear safety and the disposal of nuclear materials. For those hoping for a bright new dawn of carbon-free energy, the IEA report has some sobering news: there are continuing largescale investments in coal – the most polluting of fuels. More than US$60 billion was invested in coal projects last year, most of it in Asia and in Australia. Many of the coal plants constructed are described as sub-critical – severely polluting, and using only basic technology. The continued investment in coal was often due to the lack of the necessary infrastructure to support other, cleaner energy systems in countries such as India and Indonesia, and to the failure of governments to back renewables. Energy spending China continues to be the world’s biggest producer and consumer of coal, although the IEA says 60% of the country’s total energy spending last year was on renewables. The IEA predicts that investment in fossil fuels is likely to continue to fall in the years ahead, particularly in the oil industry. But the energy sector − especially transport − will remain dependent on oil and gas. The liquefied natural gas (LNG) market will grow substantially, and countries in the Middle East and Russia will continue to expand their oil production. The IEA welcomes the shift in investment to renewable forms of energy, but says new oil production needs to come on stream in order to meet international energy demand. Production from oil fields around the world is declining, and Birol says: “Every second year we lose [the equivalent of] one Iraq due to the decline in oil field production. This is worrying from an IEA perspective.” – Climate News Network Acknowledgement: utm_source=Climate+News+Network&utm_campaign =7fec240f04- Fossil_fuels_nosedive9_17_2016&utm_medium=email&ut m_term=0_1198ea8936-7fec240f04-38801077 File:Nellis_AFB_Solar_panels.jpg Jürgen from Sandesneben, Germany
