Solar, wind may be the cheapest sources of new energy

Solar and wind may now be the cheapest sources of new energy supply in the United Arab Emirates, according to a report released yesterday by the UAE Ministry of Foreign Affairs, the International Renewable Energy Agency, IRENA, and Masdar Institute of Science and Technology.
Marking the country's first public comparison of different energy technology costs and potentials, the Renewable Energy Prospects: United Arab Emirates report finds that the UAE could achieve a 10 percent share of renewable energy in its total energy supply – and almost 25 percent in the power sector – resulting in energy system savings of US$1.9 billion (Dh 7 billion) annually by 2030.
"Renewables have decisively emerged from a niche technology to a major component of the energy mix and have been the majority of global power capacity additions for the last three years," according to Adnan Z. Amin, IRENA Director-General. "The dramatic technology cost declines we are mapping present a real possibility to move to a sustainable energy future even in the hydrocarbon producers in the MENA region."
The report, developed by Masdar Institute in collaboration with IRENA and the UAE Ministry of Foreign Affairs, leverages local resource expertise and earlier UAE energy modelling efforts. To create a portfolio of renewable energy options and their associated costs for the UAE Masdar Institute, researchers localised an IRENA energy model and applied the results.
The report cites sharp declines in renewable energy costs in the UAE, as well as rising costs for natural gas as domestic production declines and the country turns to more expensive imported sources, as the key drivers for renewable energy's financial attractiveness. Solar PV costs, for instance, have fallen by 80 percent since 2008, while the cost of new gas supplies in the UAE has grown from under US$2.5/MMBtu in 2010 to US$6-8/MMBtu for domestic production and US$10-18/MMBtu for imports today, even after the recent decline of oil and LNG prices. The report estimates that solar, wind, and waste-to-energy sources are preferable for power generation when new gas is above US$8/MMBtu – making them immediately competitive in the UAE, where natural gas supplies almost 100 percent of power.
The report also reveals that solar costs are poised to decrease even further. In January, the tender for the second phase of Mohammed bin Rashid Solar Park in Dubai was awarded to the lowest bidder for under six cents per kilowatt hour for a 25-year fixed contract. This is the lowest solar price ever achieved worldwide.
"This report is an eye-opener," said Dr. Fred Moavenzadeh, President of Masdar Institute. "It provides policymakers and investors with an objective cost baseline, making the clear case that renewables, and especially solar, will have a much larger role sooner than we ever expected in the UAE and Middle East."
The report is one of the first three country analyses under IRENA's 'REmap 2030' project, which evaluates how the world can meet the United Nations' Sustainable Energy for All goal of doubling the global share of renewable energy by 2030. The project maps how renewable energy can grow in the power, industry, buildings, and transport sectors. Health and environmental benefits are also included in the analyses, and in the case of the UAE, they could amount to additional annual net savings of US$1bn to 3.7bn by 2030.
"The UAE made an early bet on energy diversification," said Dr. Thani Ahmad Al Zeyoudi, the UAE's Permanent Representative to IRENA and the Director of Energy and Climate Change at the Ministry of Foreign Affairs. "We are investing broadly and letting technologies compete to produce the optimal supply mix. As this report shows, there is now a clear financial case for renewables, even before we consider benefits like energy security, emissions, and job creation."
The report notes that solar and wind are still challenged by intermittency, which will require natural gas to fill gaps in output. However, the savings from generating solar power during the daytime, instead of consuming gas, are so great that they could justify 17,500 megawatts of PV in the UAE by 2030, up from around 40 MW today.
