01 Global Overview

Renewable energy provided an estimated 19% of global final energy consumption in 2012i, and continued to grow strongly in 2013.ii 1 Of this total share in 2012, traditional biomassiii, which currently is used primarily for cooking and heating in remote and rural areas of developing countries, accounted for about 9%, and modern renewables increased their share to approximately 10%.

The combined modern and traditional renewable energy share remained about level with 2011, even as the share of modern renewables increased.2 This is because the rapid growth in modern renewable energy is tempered by both a slow migration away from traditional biomass and a continued rise in total global energy demand.3

Modern renewable energy is being used increasingly in four distinct markets: power generation, heating and cooling, transport fuels, and rural/off-grid energy services. The breakdown of modern renewables, as a share of total final energy use in 2012, was as follows: hydropower generated an estimated 3.8%; other renewable power sources comprised 1.2%; heat energy accounted for approximately 4.2%; and transport biofuels provided about 0.8%.4 (See Figure 1.)

During the years 2009 through 2013, installed capacity as well as output of most renewable energy technologies grew at rapid rates, particularly in the power sector.5 (See Figure 2.) Over this period, solar photovoltaics (PV) experienced the fastest capacity growth rates of any energy technology, while wind saw the most power capacity added of any renewable technology. The use of modern renewables for heating and cooling progressed steadily, although good data for many heating technologies and fuels are lacking.6 (See Sidebar 1, page 23.) Biofuels production for use in the transport sector slowed from 2010 to 2012, despite high oil prices, but picked up again in 2013.7

As renewable energy industries and markets mature, they ncreasinglyface new and different challenges—as well as a wide range of opportunities. In Europe, a growing number of countries has reduced, sometimes retroactively, financial support for renewables at a rate that exceeds the decline in technology costs. Such actions have been driven, in part, by the ongoing economic crisis in some member states, by related electricity over-capacity, and by rising competition with fossil fuels. Policy uncertainty has increased the cost of capital—making it more difficult to finance projects—and reduced investment. (See Policy Landscape section.) During 2013, Europe continued to see a significant loss of start-up companies (especially solar PV), resulting in widespread financial losses.8 On a bright note, the share of renewables in gross final energy consumption in the European Union (EUiv) reached an estimated 14.1% in 2012, up from 8.3% in 2004.9

iii - Traditional biomass refers to solid biomass that is combusted in inefficient, and usually polluting, open fires, stoves, or furnaces to provide heat energy for cooking, comfort, and small-scale agricultural and industrial processing, typically in rural areas of developing countries. It may or may not be harvested in a sustainable manner. Traditional biomass currently plays a critical role in meeting rural energy demand in much of the developing world. Modern biomass energy is defined in this report as energy derived efficiently from solid, liquid, and gaseous biomass fuels for modern applications. (See Glossary for definitions of terms used in this report.) There is ongoing discussion about the sustainability of traditional biomass, and whether it should be considered renewable, or renewable only if it comes from a sustainable source. For information about the environmental and health impacts of traditional biomass, see H. Chum et al., "Bioenergy," in Edenhofer et al., eds., IPCC Special Report on Renewable Energy Sources and Climate Change Mitigation (Cambridge, U.K.: Cambridge University Press, 2011).

Further, renewables operate on an un-level playing field in which energy prices do not fully reflect externalities. global subsidies for fossil fuels and nuclear power remain high despite discussions about their phase-out, encouraging inefficient energy use while also hindering investment in renewables.10 Depending on the calculation method used, estimates for the global cost of fossil fuel subsidies range from USD 544 billion to USD 1.9 trillion—several times higher than those for renewable energy.11 (See Sidebar 6, GSR 2013.)

Electric grid-related challenges continued in 2013. These include lack of transmission infrastructure in some locations, delays in grid connection, and sometimes the curtailment of renewable generation.12 At high penetration levels, variable renewables can pose challenges for electricity grid system operators. A growing number of countries is aiding integration through improvements in grid management practices, improving system flexibility, and modifying existing grid infrastructure and technologies.13 (See Feature, GSR 2013.)

Overall, with some exceptions in Europe and the United States, renewables saw a number of significant and positive developments in 2013.14 Wind power moved more firmly into Africa and Latin America; concentrating solar thermal power (CSP) shifted its focus further to the Middle East and North Africa (MENA) region and to South Africa; renewable process heat fuelled industries from Chile to Europe to India; and solar PV continued to spread across the globe, with most capacity on-grid but also significant increases in off-grid markets in developing countries.

Such developments make it increasingly evident that renewables are no longer dependent upon a small handful of countries. Indeed, during 2013, major renewable energy companies further shifted their focus away from traditional markets in Europe and into Africa, Asia, and Latin America, where strong new markets are emerging in all sectors, both on and off the grid.15

Renewables have been aided by continuing advances in technologies, falling prices, and innovations in financing, driven largely by policy support. These developments are making renewable energy more economical than new fossil and nuclear installations under many circumstances, and thus more affordable for a broader range of consumers in developed and developing countries.16 In addition, there is increasing awareness of renewable energy technologies and resources, and their potential to help meet rapidly rising energy demand, while also creating jobs, accelerating economic development, reducing local air pollution, improving public health, and reducing carbon emissions.17

There is also a growing recognition that renewable energy can expand access to modern energy services in developing countries, both rapidly and cost effectively.18 As more attention turns to issues of energy access, as prices decline, and as new business models emerge, it is becoming apparent that rural energy markets in developing countries offer significant business opportunities, and products are being tailored specifically to meet the needs of these markets.19 (See Distributed Renewable Energy section.)

Increasingly, renewable energy is considered crucial for meeting current and future energy needs. In Latin America, for example, renewables are now seen as a critical energy source.20 (See Sidebar 2.) To achieve a variety of energy security and sustainability goals, growing numbers of cities, states, and regions around the world seek to transition to 100% renewable energy in individual sectors or economy-wide, and many have already achieved their targets.21

SIDEBAR 1. RENEWABLE ENERGY DATA: CURRENT STATUS AND CHALLENGES OF CAPACITY AND PRODUCTION DATA

Reliable, accessible, and timely data on renewable energy are essential for establishing energy plans, defining baselines for targets, monitoring progress and effectiveness of policy measures, and attracting investment. Global data collection on renewables has improved significantly in recent years with more-comprehensive and timelier record keeping, increased accessibility, and better communication among stakeholders. Significant gains have been made over the past decade as governments, industries, and other entities have improved data collection methods. However, there are still large data gaps, particularly in the decentralised applications of renewable energy. The task also grows in complexity as the use of renewable energy increases in scale and expands geographically, making data more difficult to track. A number of challenges remain.

In many countries, renewable energy data are not collected systematically and, where data do exist, they vary widely in quality and completeness. Timing of data releases varies considerably, and reporting periods differ. The time lag between developments and availability of data (in many instances two years or longer) can be a barrier to informed decision making, given the rapidly evolving renewable energy landscape.

Some challenges are technology or sector specific, due to the decentralised nature of installations and industry structure. For example, most traditional biomass is used for heating and cooking in more than a billion dwellings worldwide, and estimates of total quantities are uncertain. Modern biomass technologies have varying rates of fuel-to-energy conversion, and the wide range of feedstocks, sources, and conversion pathways makes uniform data collection difficult. Even the energy from traded biomass is difficult to track because the traded feedstock can have both energy and non-energy uses.

Renewable heating (and cooling) data, in general, present a challenge because of the relatively large number and variety of technologies involved (e.g., feedstocks, energy conversion technologies, distribution) and the distributed nature of the sector. In some countries, there is a misconception that the use of renewable heating (such as solar thermal collectors for water heating) is an energy efficiency measure, and thus developments are not recorded with other renewable energy data. Capacity and output data on distributed heat, off-grid electricity, and other decentralised applications frequently go uncollected or are otherwise fragmented.

Energy output data are challenging to estimate accurately for a variety of reasons, including variability in local resource and system conditions. Where renewables are part of hybrid facilities (such as biomass co-firing, CSP-fossil fuel hybrids), output is often not broken down by source, resulting in over-or underestimation of the renewable component. In addition, declining efficiencies of existing stock and retirement and replacement of ageing capacity need to be accounted for, but these are seldom reported and therefore are often subject to estimation.

Many national and international entities do not report data sources and assumptions underlying their statistics. Some data are aggregated under the "other" category, which may or may not include non-renewable products. Other datasets are not publicly available. Methodologies and assumptions (including what is counted and how) can differ markedly among sources, creating inconsistencies and uncertainty about data robustness.

Formal (government) data may command some premium in the hierarchy of data, but informal data are also critical for establishinga more comprehensive view of the global renewable energy sector. The challenge is to effectively bring together data from various institutional and individual sources in a consistent, systematic, and transparent context. Several national, regional, and international initiatives have been formed to overcome gaps and improve the quality of renewable energy data, in part by systematically relying on a broader array of both formal and informal sources. These include the Global Tracking Framework under SE4ALL, projects underway at IRENA, regional initiatives in western Africa and the MENA region, and ongoing work by REN21 with global and regional status reports.

The collection and processing of renewable energy statistical information can be seen as burdensome; however, inconsistent data collection efforts hamper governments' capacity to make informed decisions. Experts agree that systematic and enhanced reporting is critical for increasing financing, establishing policy priorities, and improving energy planning over time.

SIDEBAR 2. REGIONAL SPOTLIGHT: LATIN AMERICA AND THE CARIBBEAN

Increasing interest in renewable energy in the Latin America and the Caribbean (LAC) region is reflected in ambitious targets and policy support, which have led to rapidly growing investments in renewables, beyond the traditional hydropower sector. By early 2014, at least 19 countries in the region had renewable energy policies, and at least 14 had renewable energy targets, mostly for electricity generation. (See Table 3 and Reference Tables R12 to R15.) For example, Uruguay aims to generate 90% of its electricity from renewable sources by 2015, while Grenada targets 20% primary energy from renewables by 2020.

Renewable energy already meets a substantial portion of electricity demand, with hydropower accounting for around half of the region's total installed power capacity and the vast majority of its renewable power capacity. Especially in Central America, the need for a diversified electricity mix to reduce vulnerability to a changing hydrological profile is driving interest in other abundant renewable energy resources. In Brazil, hydropower expansion is expected to become increasingly constrained by environmental sensitivity and the remoteness of much of the remaining resource. In the Caribbean, countries are aggressively pursuing the deployment of renewables to reduce their heavy reliance on fossil fuels, and thereby increase their economic and energy security.

Despite having an average electrification rate of almost 95%, one of the highest among the developing regions, energy access remains a challenge for the LAC region: an estimated 24 million people, primarily in rural and remote areas, still lack access to electricity. Some countries have achieved virtually 100% electrification, while others have far to go. Renewables can play an important role in achieving universal access to modern energy. Solar energy is abundant across the region, which is also home to nearly one-quarter of the world's geothermal potential, and wind resources are world class in Argentina, Brazil, and Mexico. By one estimate, non-hydro renewable energy has the technical potential to meet more than 50 times the region's current electricity demand.

While the region's hydropower sector is relatively mature, the vast potential of non-hydro renewables is now beginning to be realised. Wind power has experienced the fastest growth in recent years, with Brazil and Mexico leading the way. With about 1 gigawatt (GW) of geothermal capacity, Mexico is the world's fifth-largest geothermal power producer, followed in the LAC region by Central America, with a collective 500 MW of capacity. The solar PV market, while increasingly important in off-grid and rural areas, has experienced a shift in focus from small domestic applications to large-scale power plants.

In the heating sector, renewable energy applications for domestic, commercial, and industrial use are gaining ground. Solar thermal collectors for water heating are spreading beyond Brazil, one of the world's top markets. Chile's mining industry is actively installing solar thermal systems (parabolic trough and flat-plate collectors) to meet its heat energy needs in remote locations. Solar food dryers are used for processing fruits and coffee in Jamaica, Peru, and Mexico.

Over 80% of the LAC population lives in cities, and the region is urbanising at a rapid pace, with increasing demand for transportation. To meet this demand while slowing the growth of fossil fuel consumption, several countries are promoting the use of biofuels. Biofuels account for 13% of transport fuel in Brazil, and their role is growing in several other countries. Brazil, Argentina, and Colombia lead the region for biofuel production.

Several countries have adopted feed-in tariffs, public competitive bidding (tendering), tax incentives, and quotas to drive deployment. The use of public competitive bidding has gained momentum in recent years, with Brazil, El Salvador, Peru, and Uruguay issuing tenders in 2013 for more than 6.6 GW of renewable electric capacity. Eight countries had net metering laws by year's end, with pilot projects operating in Costa Rica and Barbados.

An improved environment for renewables is attracting new national and international investors. Although Brazil experienced a decline in new investment in 2013 forthe second year running, others in the region sawsignificant increases, with Chile, Mexico, and Uruguay committing over USD 1 billion each.

Manufacturers are seeking growth opportunities in the region. While the larger economies-Brazil, Argentina, Chile, and Mexico-are the front-runners, manufacturing of renewable energy technologies, such as wind turbines, is spreading across the region.

Differences in electricity market structures and regulations have constrained efforts to integrate electricity markets regionally to date, and lack of transmission infrastructure has delayed the development of some projects. Lack of awareness about renewable heat technologies and their potential is impeding their expansion. In addition, the relatively low level of energy demand in some countries—such as the Caribbean nations—makes it difficult to support local industry and can preclude the potential to benefit from economies of scale. Despite a number of near-term challenges, the region is demonstrating unprecedented growth and presents significant opportunities for expansion.

As markets have become more global, industries have responded by increasing their flexibility and developing global strategies and supply chains.22 In 2013, manufacturers continued to diversify products to increase product value, and many advanced further into projectdevelopmentand ownership. Many renewable industries saw a rapid increase in worldwide demand for construction and engineering, consulting, equipment maintenance, and operations services.23 Several industries had a difficult year, with consolidation continuing, particularly in solar energy and wind power. But the picture brightened by year's end, with many solar PV and wind turbine manufacturers returning to profitability.24

Global investment in renewables declined again in 2013, largely due to falling system costs and policy uncertainty.25 Still, renewables outpaced fossil fuels for the fourth year running in terms of net investment in power capacity additions.26 Further, 2013 was a watershed year for renewable energy financing, with the development and enactment of new financing structures that provide access to low-cost money through capital markets.27 (See investment Flows section.) Projects (particularly wind and solar PV) changed hands at record rates during the year, reflecting in part a growing interest in renewable energy asset investments among pension funds and other institutional investors that anticipate solid long-term returns.28 Innovative financing mechanisms, such as crowd funding and risk-guarantee schemes, continued to expand and spread across China, Europe, and the United States, and are increasingly targeting off-grid projects in Africa and Asia.29 A range of actors continued to actively engage in the financing of distributed renewable energy projects for isolated regions of the developing world.30

The impacts of all of these developments on employment numbers in the renewable energy sector have varied by country and technology, but, globally, the number of people working in renewable industries has continued to rise. (See Sidebar 6, page 60, and Table 1, page 63.)

26 Global investment in fossil fuel power capacity was USD 270 billion; however, most of this was to replace previously existing capacity, and investment in additional fossil power capacity was an estimated USD 102 billion. This compares with USD 192 billion for renewables not including hydro plants larger than 50 MW, and at least USD 227 billion if all hydro is included, from ibid., pp. 30-32.
