A new report by the International Renewable Energy Agency (IRENA), the International Energy Agency (IEA), and the Renewable Energy Policy Network for the 21st Century (REN21), Renewable Energy Policies in a Time of Transition, is an unprecedented collaboration that sheds new light on the policy barriers to increased deployment of renewables and provides a range of options for policymakers to scale-up their ambitions.
Since 2012, renewable energy has accounted for more than half of capacity additions in the global power sector. In 2017 alone a record-breaking 167 GW of renewables capacity was added worldwide. 146 million people are now served by off-grid renewable power, and many small island developing states are advancing rapidly towards targets of 100% renewables.
One of the main rationales behind the call for a higher share of renewables in the energy mix is the urgent threat posed by climate change. Of the 194 parties to the United Nations Framework Convention on Climate Change 145 referred to renewable energy in their nationally determined contributions (NDCs), and 109 included quantified renewable energy targets. Air pollution is also a pressing issue, with an estimated 7.3 million premature deaths per year attributable to household and outdoor air pollution. Energy security is another influencing factor, with small island states particularly affected by security issues and resilience in the face of natural disasters. Finally, countries looking to expand energy access in rural areas are increasingly turning to renewables as the most cost-effective, cleanest and most secure option.
But the pace of the energy transition needs to be substantially accelerated to meet decarbonisation and sustainable development objectives. As outlined in IRENA’s recently-released Global Energy Transformation: A Roadmap to 2050, to achieve the two-degree goal of the Paris target, the share of renewables in the primary global energy supply must increase from 15% today to 65% by 2050. Gains in the electricity sector must be matched in end-use sectors such as heating and transportation, which together account for 80% of global energy consumption.
Renewable Energy Policies in a Time of Transition provides policymakers with a comprehensive understanding of the diverse policy options to support an accelerated development of renewables across sectors, technologies, country contexts, energy market structures, and policy objectives, to scale up renewable energy deployment. An updated joint classification of renewable energy policies to illustrate the latest policy developments around the world.
Heating accounted for over 50% of total final energy consumption in 2015, with over 70% of that met by fossil fuels. To increase the use of renewables, a range of policy instruments are required. These include mandates and obligations, which can offer greater certainty of increased deployment; building codes, which implicitly support renewable heating and cooling from renewables by setting energy performance requirements; renewable heat and energy efficiency policies that are closely aligned to leverage synergies and accelerate the pace of transition; fiscal and financial incentives, which reduce the capital costs of renewables; and carbon or energy taxes, which provide important price signals and reduce externalities.
Transport is the second largest energy end‑use sector, accounting for 29% of total final energy consumption in 2015, and 64.7% of world oil consumption. With the exception of biofuels, there is little practical experience of fostering renewables in transport. Policies and planning should help overcome the immaturity or high cost of certain technologies, inadequate energy infrastructure, sustainability considerations and slow acceptance among users as new technologies and systems are introduced. They should also build improved understanding between decision makers in the energy and transport sectors, so as to enable integrated planning and policy design. Removal of fossil fuel subsidies is also essential, especially in shipping and aviation.
Although the power sector consumed only about a fifth of total final energy consumption in 2015, it has received the most attention in terms of renewable energy support policy. Investments in the sector are largely driven by regulatory policies such as quotas and obligations and pricing instruments, supported by fiscal and financial incentives. Quotas and mandates cascade targets down to electricity producers and consumers, but require a robust framework to monitor and penalize non-compliance. Administratively set pricing policies (like feed-in tariffs and premiums) need to continuously adapt to changing market conditions and the falling cost of technology. Auctions are being increasingly adopted, given their ability for real-price discovery, and have resulted in a five-fold price reduction between 2010 and 2016, though auction design is crucial.
A number of countries and regions are reaching high penetrations of VRE in their power systems, and implementing policies to facilitate their system integration. Strategies for system integration of renewables are crucial to minimise negative impacts, maximize benefits and improve the cost effectiveness of the power system. As VRE shares grow in the power system, so do the challenges of system integration.
A wide range of policies have been adopted to support the growth of renewable energy around the world. The nature of those policies in a given country depends on the maturity of the sector, the particularities of the market segment, and wider socio-economic conditions. As this report shows, as deployment of renewable energy has grown and the sector has matured, policies must adapt and become more sophisticated to ensure the smooth integration of renewables into the wider energy system - including the end-use sectors - and a cost-effective and sustainable energy transition.
