15 FOREWORD Renewable power accounted for 70% of net additions to global power generating capacity in 2017, but global energy-related carbon dioxide emissions rose 1.4% in 2017, after three years of holding steady. The increase in carbon emissions was the result of robust global economic growth (of 3.7%), lower fossil fuel prices and weaker energy efficiency efforts. This year’s Renewables 2018 Global Status Report (GSR) reveals two realities: one in which a revolution in the power sector is driving rapid change towards a renewable energy future, and another in which the overall transition is not advancing with the speed needed. While momentum in the power sector is positive, it will not on its own deliver the emissions reductions demanded by the Paris climate agreement or the aspirations of Sustainable Development Goal 7. The heating, cooling and transport sectors, which together account for about 80% of global total final energy demand, are lagging behind. But the news is not all bad. Renewable power generation capacity saw its largest annual increase ever with an estimated 178 gigawatts added globally. New solar photovoltaic generating capacity alone was greater than additions in coal, natural gas and nuclear power combined. And while China, Europe and the United States accounted for nearly 75% of the global investment in renewable power and fuels, 2017 saw significant investment in developing country markets. When measured per unit of gross domestic product, the Marshall Islands, Rwanda, the Solomon Islands, Guinea-Bissau and many other developing countries are investing as much as or more in renewables than developed and emerging economies. These positive developments need to be scaled up for a global energy transition. Corporate sourcing of renewable power is also on the rise. Initially many companies saw the adoption of renewable energy solutions mainly as an act of corporate social responsibility. Significant reductions in renewable energy costs, however, as well as maturing market and policy environments, have made renewables cost-competitive and attractive sources of energy in their own right. As this year’s report shows, corporate renewable energy sourcing has moved beyond the United States and Europe and is now found in countries such as Burkina Faso, Chile, China, Egypt, Ghana, India, Japan, Mexico, Namibia and Thailand. Better reporting is needed to reflect the myriad developments happening at the small scale and in end-use sectors. Grassroots efforts, decentralised solutions, innovation, start-ups, off-grid applications, solar thermal and other activities are not visible when reporting at - the global level, yet collectively they make a significant contribution. These developments offer opportunities for scaling up and further ing the transition in the energy system. Collecting data and tracking the evolution of small-scale solutions as well as how renewables are being used in key sectors such as transport and agriculture must be a new priority. Building on the data, and in an attempt to present an increasingly complex picture in the renewables sector, REN21 has created Advancing the Global Renewable Energy Transition: Highlights of the REN21 Renewables 2018 Global Status Report in Perspective . Like its 2017 predecessor, this document presents the overarching trends and developments from 2018 so that policy makers and others can more easily understand the significance of the latest renewable energy developments. Attention is paid to the uneven distribution of renewables at both the sector and regional levels. The document complements the Renewables 2018 Global Status Report . In closing, I would like to thank all those who have contributed to the successful production of this year’s report. At its heart is a multi-stakeholder network of more than 900 experts who give their time and expertise. They are complemented by the research direction and lead authoring team Janet L. Sawin, Jay Rutovitz and Freyr Sverrisson, the section authors, GSR Project Manager Hannah E. Murdock and the dedicated team at the REN21 Secretariat, under the leadership of Executive Secretary Rana Adib and her predecessor, Christine Lins. Arthouros Zervos Chair, REN21 15

16 ES EXECUTIVE SUMMARY AkzoNobel, DSM, Google and Philips formed a unique partnership to jointly sign two power purchase agreements (PPAs) in 2016 to create two wind power projects – Krammer and Bouwdokken – in Zeeland, the Netherlands. Together, these two wind parks have a total capacity exceeding 140 MW, Bouwdokken Windpark, Zeeland, enough to power some 128,800 EU households. The consortium represents a potentially replicable model The Netherlands for multiple renewable energy buyers to aggregate their electricity demand under a single PPA deal. 16

At the same time, many developing and emerging countries are expanding their deployment of and investment in renewables and related infrastructure. The private sector is also increasingly playing a role in driving the deployment of renewable energy through its procurement and investment decisions. As of 2016, renewable energy accounted for an estimated 18.2% of global total final energy consumption, with modern renewables representing 10.4%. The number of countries with renewable energy targets and support policies increased again in 2017, and several jurisdictions made their existing targets more ambitious. Strong growth continued in the renewable power sector, while other renewable sectors grew very slowly. Solar photovoltaic (PV) i “Heating and cooling” in this report refers to thermal applications including climate control/space heating, heat for industrial use, cooking, agricultural drying, etc. 17

(3.1%), with more than 90% provided by liquid biofuels. Electrification of the transport sector expanded in 2017 – with electric vehicles (EVs) exceeding 1% of global light vehicle sales – and a number of countries announced plans to phase out sales of petrol and diesel vehicles. There are signs that the shipping and aviation sectors also may become open to electrification. Further electrification of the transport sector has the potential to create a new market for renewable energy and to facilitate the integration of higher shares of variable renewable energy, provided that the policy and market settings are suitable. More solar PV capacity was added in 2017 than the net additions of coal, gas and nuclear combined 18

Policies coupling the thermal (heating and cooling), transport and power sectors – and policies increasing the linkages between renewable energy and energy efficiency – continue to emerge slowly. New cross-sectoral integrated policies were introduced in 2017 in several countries, including Indonesia and Switzerland. Renewable energy and energy efficiency also are being advanced in some cases by climate change policies, including under commitments to achieve net-zero emissions or through specific mechanisms such as carbon taxes, the elimination of fossil fuel subsidies, and emissions trading schemes. In 2017, China launched the world’s largest emissions trading scheme, with the first phase of the new cap-and-trade programme focusing on the country’s power sector. Targets remain one of the primary means for policy makers to 57 countries express their commitment to renewable energy deployment. Targets are enacted for economy-wide energy development as have 100% renewable well as for specific sectors. As of year-end 2017, targets for the electricity targets renewable share of primary and final energy were in place in 87 countries, while sector-specific targets for renewable power were in place in 146 countries, for renewable heating and cooling in 48 countries, and for renewable transport in 42 countries. 20

Policies that promote fleets, including city rail systems. grid services, such as synthetic inertia and voltage regulation, as well as enabling technologies such as energy storage, are POLICIES FOR ELECTRICITY increasingly playing a role in the advancement of energy systems. Use of tendering continues to spread, yet feed-in policies Similarly, some policy makers are starting to take a systems view, remain vital in support schemes for renewables. introducing cross-sectoral policies that advance the coupling of electricity, transport, and heating and cooling to provide As renewable power technologies and markets have matured, economy-wide benefits. policy makers have grappled with new challenges related to integrating renewable electricity into power systems. Many countries are moving away from some of the policy mechanisms that served as the foundational elements of numerous renewable energy support programmes. Developed countries have followed the lead of emerging economies such as Brazil and South Africa by continuing to replace feed-in policies with renewable energy tenders. More than 29 countries held renewable energy tenders in 2017. Feed-in policies remain a vital component of many national support schemes for renewables, often for promoting the development of small-scale renewable energy systems. Two countries adopted new feed-in policies in 2017 (Zambia and Vietnam), increasing the number of countries with such policies in place to 113, while rates set under many existing policies were revised. New net metering policies also were enacted in six countries in 2017, primarily to promote rooftop solar PV. 21

As other cost-competitive options have energy-intensive and more service-oriented industries. become available, however, many large corporations have begun considering sourcing options that allow them to play a more active role in adding new renewable capacity to the grid. The information technology sector continues to purchase by far the largest amounts of renewable energy, mainly through wind energy PPAs. Heavy industry, which has a tradition of owning energy-generating assets or holding bilateral contracts with generators, also has increased its sourcing of renewables in recent years. The options available for corporations to source renewable energy depend greatly on the markets and policy frameworks in which they operate, as well as on the nature of their operations and internal capacity. In response to rising corporate interest in renewable energy sourcing, several initiatives have been established to recognise and further support the development and pursuit of ambitious renewable energy goals through various sourcing options. The importance of integrating energy efficiency and renewable energy is increasingly recognised 27

Heat consumption remains heavily fossil fuel-based. The largest share of renewable heating is associated with traditional biomass for heating and cooking in developing countries, which accounts for 79 some 16.4% of global heat demand. This traditional use of biomass – often in open fires or very inefficient indoor stoves – leads to significant health problems and is often linked to unsustainable levels of fuelwood collection. In developing countries in particular, energy access efforts focus on providing clean cooking solutions ( to replace such practices. See Distributed Renewables chapter.) p Only 10.3% of the heat used worldwide in 2015 was produced from 80 modern renewables, including renewably generated electricity. However, there is increasing appreciation of the role that renewables can play in heating. Renewable energy can serve thermal demand when supplied by electricity, either directly or through the use of heat pumps. Electricity is estimated to account for more than 7% of total heat demand in buildings and industry, with about one-quarter of this 35

However, it is an indication that renewable energy’s share of net capacity additions rose significantly in 2017 relative to 2016. 40

( This is due primarily to the shift in policies from feed-in tariffs (FITs) i For multiple reasons, tender prices may be lower than LCOEs. For example, bids may include annual adjustments, and tender conditions might include the provision of grid connection to developers. In addition, bids reflect expected future rather than current costs. 41

In some cases, countries also are investing in energy storage capacity (mostly pumped storage). Countries leading the way in VRE penetration include Denmark (nearly 53%), Uruguay (28%) and Germany (26%); Ireland, Portugal and Spain also have VRE penetration levels above 206 ( p See Figure 8 and Integration chapter.) 20%. A number of countries and regions integrated much higher shares of VRE into their energy systems as instantaneous shares of total demand for short periods during 2017.

Tendering (also called auction/reverse auction or tender) is a procurement mechanism by which renewable energy supply or capacity is competitively solicited from i sellers, who offer bids at the lowest price that they would be willing to accept. Individual tenders may vary by qualifying technology, capacity offered, etc., and may be evaluated on both price and non-price factors. Net metering is a regulated arrangement in which utility customers with on-site electricity generators can receive credits for excess generation that is fed into ii the grid, which can be applied to offset consumption. Under net metering, customers typically receive credit at the level of the retail electricity price. Under net billing, customers typically receive credit for excess power at a rate that is lower than the retail electricity price. Different jurisdictions may apply these terms in different ways, however. Policy Spotlight: Vietnam Solar PV Promotion BOX 3.

India’s total i All references to ethanol in the GSR refer to bioethanol, that is, ethanol derived from biomass. Ethanol is produced principally from sugar- and starch-containing materials including corn, sugar cane, wheat and cassava. After pre-treatment and fermentation the ethanol is separated by distillation. Most biodiesel is made by chemically treating vegetable oils and fats (including palm, soy and canola oils, and some animal fats) to produce FAME biodiesel. Ethanol and biodiesel are collectively referred to as “conventional biofuels”. While FAME fuels can be used in diesel engines, their properties depend on their origin and differ from those of fossil-based diesel, so they are usually used as a blend with fossil diesel products. An alternative is to take the oils and treat them with hydrogen to produce a hydrocarbon product that then can be refined to produce fuels with properties equivalent to those of a range of fuels derived from fossil fuels such as diesel or jet fuel. These fuels are described as HVO/HEFA and sometimes as renewable diesel. (See, for example, Aviation Initiative for Renewable Fuels in Germany, “Hy - dro-processed esters and fatty acids (HEFA)“, http://www.aireg.de/en/production/hydro-processed-esters-and-fatty-acids-hefa.html.) In addition, a range of other biofuels are produced at a much smaller scale, including ethanol from cellulosic feedstocks, pyrolysis oils, etc. See Liquid Fuels Industry section of the Bioenergy text for further details and references. 72

In a binary plant, the geothermal fluid heats and vaporises a separate working fluid that has a lower boiling point than water; the fluid drives a turbine to iv generate electricity. Each fluid cycle is closed, and the geothermal fluid is re-injected into the heat reservoir. The binary cycle allows an effective and efficient extraction of heat for power generation from relatively low-temperature geothermal fluids. Organic Rankine Cycle (ORC) binary geothermal plants use an organic working fluid, and the Kalina Cycle uses a non-organic working fluid.

124 04 DISTRIBUTED RENEWABLES FOR ENERGY ACCESS As of 1 February 2018, Aguas Chañar, a water-cycle management company in Atacama, Chile, began using electricity from renewable sources under a long-term PPA with Acciona Energia of Spain. El Romero All the electricity supplied under the PPA comes from Acciona’s 246 MW El Romero Solar power plant in the Solar photovoltaic Atacama Desert and its 45 MW Punta Palmeras wind farm in the region of Coquimbo. The contract power plant, covers more than 70% of Aguas Chañar’s electricity needs across several installations. Atacama, Chile

PAYG has two main approaches: energy as a service approach whereby the customer pays for the electricity provided and does not own the system, and the lease-to-own model whereby the customer becomes the owner of the system after a period of time. The lease-to-own model is the most prominent one. For example, in South Africa, a household is considered to have access to electricity if it is supplied with 50 kilowatt-hours (kWh) per month, while a village in India iii is considered electrified if electricity is provided to social institutions such as schools and health centres and to 10% of households. This refers to the use of inefficient, unhealthy and unsafe open fires as well as rudimentary cook stoves running on solid fuels such as biomass, coal and iv animal waste for daily cooking needs. 126

An estimated USD 310 billion was committed to constructing new renewable power plants (including i without large-scale hydropower, plus an USD 265 billion twice estimated USD 45 billion for hydropower projects larger than 50 MW). This compares to approximately USD 103 billion that in fossil fuels and committed to fossil fuel-fired generating capacity and nuclear combined USD 42 billion for nuclear power capacity. Overall, renewable energy accounted for about 68% of the total amount committed ( p to new power-generating capacity in 2017. See Figure 51.) i This number is for renewable power asset finance and small-scale projects. It differs from the overall total for renewable energy investment (USD 278.9 billion) provided elsewhere in this chapter because it excludes biofuels and some types of non-capacity investment, such as equity-raising on public markets and development R&D. .

147 05 SOURCES OF INVESTMENT Most renewable energy projects are financed either on-balance- sheet by a utility, by an independent power producer or other investor, or by non-recourse project finance that is largely made up of debt from banks. Generally, non-recourse debt finance for Renewables made up projects takes the form of bank loans. In 2017, on-balance-sheet INVESTMENT FLOWS financing by utilities and energy companies was up 2% from 2016, to USD 121.5 billion, and non-recourse project finance decreased % 68.2 4%, to USD 91.2 billion. of g lobal investment i jumped 67% to a record In 2017, global issuance of green bonds in new power capacity USD 163.1 billion. The strong growth in green bonds was related to a leap in the volume of asset-backed securities issued (mostly linked to residential solar PV systems in the United States), to growth in green bond issuance by sovereign governments, including those of France, Fiji and Nigeria, and to a jump in issuance by non-financial corporations. In addition to commercial banks and bond issues, the other major source of debt for renewable power assets is borrowing directly from the world’s large array of national and multilateral development banks. Aggregate figures for development bank lending to renewables in 2017 were not yet available at the time of publication. Among those that had published data in early 2018, the European Investment Bank provided finance for renewables totalling EUR 4.7 billion (USD 5.6 billion) in 2017, up from EUR 3.9 billion in 2016. Institutional investors such as insurance companies and pension funds tend to be more risk-averse and therefore are interested in the predictable cash flows of a project already in operation. Nonetheless, in Europe, direct investment by institutional investors in renewable energy hit a record in 2017, totalling USD 9.9 billion, up 42% from 2016. i Green bonds include qualifying debt securities issued by development banks, central and local governments, commercial banks, public sector agencies and corporations, asset-backed securities and green mortgage-backed securities, and project bonds. 147

Also important for renewable energy integration, particularly for high shares of VRE, are recent developments in software controls and power electronics that are enabling wind plants to supply the inertia currently provided by large spinning turbines (found in thermal and hydropower plants) to help stabilise grid electricity. This ability to provide “synthetic inertia” – responding to rapid changes in frequency by delivering a power boost, generally after a large power plant has gone offline – is helping to overcome 57 some of the integration challenges facing VRE. Wind turbine manufacturers have continued to improve their synthetic inertia technology and are testing second-generation 58 Hydro-Québec TransÉnergie was the first grid operator systems. to mandate (in 2005) that new wind farms had synthetic inertia 59 Grid capability, and such requirements appear to be spreading. operators in Brazil, in the Canadian province of Ontario and in the US state of Texas have adopted mandates, and Europe’s i “Ride-through” is the capability of electric generators to continue operating during short periods when there is a drop in voltage, and thereby to “ride through” the dip. 153

In moderate climates, heat pumps generally are counted as air conditioning equipment, with a side benefit of dehumidification or provision of hot water. In cold climates, the heating service is much more important, and thus heat pumps are counted as heating equipment, with cooling and dehumidification considered welcome byproducts, from European Heat Pump Association, personal communications with REN21, November 2016-March 2017. 161

The definition of large-scale hydropower varies by country. 2 Final energy targets by 2020 for all EU-28 countries are set under EU Directive 2009/28/EC. The governments of Austria, the Czech Republic, Germany, Greece, Hungary, Spain and Sweden have set higher targets, which are shown here. The government of the Netherlands has reduced its more ambitious target to the level set in the EU Directive. 3 The Chinese target is for share of “non-fossil” energy. All targets include nuclear power. 4 Kosovo is not a member of the United Nations. Note: Historical targets have been added as they are identified by REN21. A number of nations have already exceeded their renewable energy targets. In many of these cases, targets serve as a floor setting the minimum share of renewable energy for the country.

De facto sub-national targets have been set through existing RPS policies. 6 Mali’s target excludes large-scale hydropower. 7 Nigeria’s target excludes hydropower plants >30 MW. 8 The Russian Federation’s targets exclude hydropower plants >25 MW. 9 Thailand does not classify hydropower installations larger than 6 MW as renewable energy sources, so hydro >6 MW is excluded from national shares and targets. 10 The United States does not have a renewable electricity target at the national level. De facto state-level targets have been set through existing RPS policies. 11 RPS mandate is for investor-owned utilities (IOUs), which are utilities operating under private control rather than government or co-operative operation. 12 RPS mandate is for co-operative utilities. Note: Unless otherwise noted, all targets and corresponding shares represent all renewables including hydropower. A number of state/provincial and local jurisdictions have additional targets not listed here. Historical targets have been added as they are identified by REN21. Only bolded targets are new/revised in 2017. A number of nations have already exceeded their renewable energy targets. In many of these cases, targets serve as a floor setting the minimum share of renewable electricity for the country. Some countries shown have other types of targets (see Tables R3, R4, R5, R6, R9, R10, R14). See Policy Landscape chapter for more information about sub-national targets. Existing shares are indicative and may need adjusting if more accurate national statistics are published. Sources for reported data often do not specify the accounting method used; therefore, shares of electricity are likely to include a mixture of different accounting methods and thus are not directly comparable or consistent across countries. Where shares sourced from EUROSTAT differed from those provided to REN21 by country contributors, the former was given preference. Source: See endnote 8 for this section. 191

Therefore, national targets and data for India do not include hydropower facilities >25 MW. 2 Pumped storage plants are not energy sources but a means of energy storage. As such, they involve conversion losses and are powered by renewable or non- renewable electricity. Pumped storage is included here because it can play an important role as balancing power, in particular for variable renewable resources. 3 Nigeria’s target excludes hydropower plants >30 MW. 4 The Russian Federation’s targets exclude hydropower plants >25 MW. 5 It is not always possible to determine whether municipal solid waste (MSW) data include non-organic waste (plastics, metal, etc.) or only the organic biomass share. Uganda utilises predominantly organic waste. 6 Investor-owned utilities (IOUs) are those operating under private control rather than government or co-operative operation. Note: All capacity targets are for cumulative capacity unless otherwise noted. Targets are rounded to the nearest tenth decimal. Renewable energy targets are not standardised across countries; therefore, the table presents a variety of targets for the purpose of general comparison. Countries on this list may also have primary/final energy, electricity, heating/cooling or transport targets (see Tables R3, R4, R5, R6, R8, R9, R14). Source: See endnote 10 for this section. 198
