The Global Outlook For Renewable Power In One Graph
By Share Print Energy produced from hydro, wind, solar, and other renewables sources is expected to exceed that from natural gas and double that from nuclear sources by 2016 – becoming the second most important energy source behind coal. Speaking at the 10 th Annual Renewable Energy Finance Forum in New York City last month, International Energy Agency (IEA) Executive Director Maria van der Hoeven said the global outlook for renewables is “robust”, with total renewable generation capacity expected to grow to nearly one-quarter of the global electricity generation capacity by 2018. Ms. van der Hoeven points to two main trends driving the renewables outlook: renewable deployment is expanding across the globe and renewables are becoming cost competitive versus fossil fuels in many circumstances. Led by investment and deployment in China, non-OECD countries are expected to account for two-thirds of the global increase in renewable power generation between now and 2018. This rapid deployment is “mainly driven by fast‐rising electricity demand, energy diversification needs, and local pollution concerns, while contributing to climate change mitigation”, according to Ms. van der Hoeven. China is expected to account for 40 percent of the global growth in renewable power capacity between 2012 and 2018. Although a large portion of China’s renewable portfolio is hydro and onshore wind, the country could have the largest deployment of solar PV systems if financial incentives and a stronger policy push are made. In addition to China, there is significant renewable deployment in Brazil, India, South Africa, and the Middle East. The IEA expects this growth to more than compensate for slower growth in Europe and the United States. COE) for onshore wind is competitive or close to competitive versus new coal or gas-fired plants in Australia, where wind is competitive versus the generation costs of new coal- and gas-fired plants with carbon pricing, and the best wind sites can compete without carbon pricing. In Turkey and New Zealand, onshore wind has been competing well in the wholesale electricity market for several years. Despite the healthy growth prospects, renewable energy deployment is becoming more complex and needs policy certainty to be successful. “To get investment at favourable rates, risks must be reduced and shared. Even for less deployed technologies such as concentrated solar power and offshore wind, technology risk is no longer seen as the main barrier to investment”, Ms. van der Hoeven explained. “The main challenge, the public enemy #1 for investors and the most important barrier to renewable energy deployment is policy uncertainty.” Countries such as Spain , Czech Republic , and Bulgaria have adopted retroactive policy changes that shake investor confidence. In the United States, uncertainty over Production Tax Credits at the end of 2012 provided little confidence for the renewable industry and investors. Reducing incentives for renewable projects is a legitimate policy action as long as the reductions “reflect cost reductions of technologies to maximize benefits to customers and tax-payers.” The IEA Medium-term Renewable Energy Market Report Executive Summary can be found here .

Europe Should Head To The Woods For Biofuels, Report Says
Posted on July 5, 2013 at 10:16 am by (AP Photo/U.S. Fish and Wildlife Service) In the European Union’s quest to reach 20 percent renewables by 2020, it should avoid the temptation to latch on to ethanol and other biofuels that drain scarce land and water resources, according to a government report issued Wednesday by the European Environment Agency. “Biomass from waste and residues from agriculture and forestry offer high resource efficiency whereas the environmental benefits from cultivating crops for bioenergy (‘energy cropping’) are often limited,” the report wrote. IEA: Renewables will surpass natural gas for power generation by 2016 Europe’s renewable targets were established in its 2009 Renewable Energy Directive, which also included a 10 percent target for transportation fuel. And while solar and wind energy have scaled up throughout Europe, reaching that 10 percent biofuel goal will be challenging, especially if ethanol is largely excluded from the mix. European consumption of ethanol grew from 2,000 barrels per day in 2001 to nearly 90,000 barrels per day in 2012, according to IndexMundi, a commodities website. But using corn-based ethanol to meet the biofuel target is being questioned, with critics saying the environment could be worse for the move. “While some bioenergy sources and technologies offer significant advantages over fossil fuel-based systems, others lead to environmental concerns,” the report said. “This is particularly the case where bioenergy involves using agricultural land to cultivate energy crops, since it often results in changes to land use, including expanding or intensifying agriculture at other locations.” Biomass: In 1776, energy was rooted in wood The issue echoes domestic debates over ethanol, with critics arguing that the benefits of ethanol are outweighed by the demands made on scare natural resources, especially water. The Energy Independence and Security Act of 2007 required refiners to blend 15 billion gallons per year of ethanol from corn with conventional motor fuel by 2022. The U.S. is also encouraging the growth of biofuels, and has mandated a target of 36 billion barrels annually of biofuels by 2022 . Continue reading
Second Gen Biofuels Most Efficient Use Of EU Bioenergy
July 10, 2013 | By Barbara Vergetis Lundin Bioenergy should be produced in line with EU objectives to use resources more efficiently, according to the European Environment Agency (EEA), including reducing the land and other resources needed to produce each unit of bioenergy and avoiding environmental harm from bioenergy production, extracting more energy from the same material input, and avoiding negative environmental effects potentially caused by bioenergy production. In 2010, bioenergy comprised approximately 7.5 percent of energy used in the EU and is expected to rise to around 10 percent by 2020, according to EU Member States’ National Renewable Energy Plans. According to the EEA analysis, the most efficient energy use of biomass is for heating and electricity as well as advanced biofuels or second generation biofuels. The research shows that the current energy crop mix is not good for the environment and recommends a broader mix of crops to reduce environmental impacts, including perennial crops which are not harvested annually like energy grasses or short rotation willow plantations to enhance ecosystem services such as flood prevention and water filtration. Bioenergy is often considered carbon neutral, as the carbon dioxide released in combustion is assumed to be compensated by the CO 2 absorbed during plant growth. However, the research shows that indirect land use change can negate any greenhouse gas savings from biofuel production based on energy crops due to the displacement of crop production onto previously unused land, which can lead to the conversion of forests and savannah to agriculture ultimately harming biodiversity and increasing greenhouse gas emissions. “Bioenergy is an important component of our renewable energy mix, helping to ensure a stable energy supply. But this study highlights the fact that forest biomass and productive land are limited resources, and part of Europe’s ‘natural capital,'” Hans Bruyninckx, EEA executive director, said. “So it is essential that we consider how we can use existing resources efficiently before we impose additional demands on land for energy production.” For more: – download the report Read more: Second gen biofuels most efficient use of EU bioenergy – FierceEnergy http://www.fierceene…0#ixzz2YfQfXVKy Subscribe at FierceEnergy Continue reading
