Renewable energy targets and other support policies now in place in 164 countries powered the growth of solar, wind and other green technologies to record-breaking energy generation capacity in 2014.
According to REN21's latest Renewables Global Status Report, policymakers continued to focus on adapting existing policies to keep pace with rapidly changing costs and circumstances.
With 135 gigawatts added, total installed renewable energy power capacity worldwide, including large hydroelectric plants, stood at 1712 gigawatts, up 8.5% from the year before and double the 800 gigawatts of capacity reported in the first REN21 report in 2005.
In 2014, renewables made up an estimated 59% of net additions to global power capacity and represented far higher shares of capacity added in several countries around the world. By year's end, renewables comprised an estimated 27.7% of the world's power generating capacity. This was enough to supply an estimated 22.8% of global electricity demand.
The quantity of electricity available from renewables worldwide is now greater than that produced by all coal-burning plants in the USA (in 2013 coal supplied ~38% of US electricity, down from ~50% in the early 2000s).
Solar photovoltaic capacity has grown at the most phenomenal rate (up 68-fold, from 2.6 GW in 2004 to 177 GW in 2014), with strong growth also in wind power capacity (up almost 8-fold, from 48 GW in 2004 to 370 GW in 2014).
Heating accounted for about half of world energy consumption in 2014. Renewable energy supplied more than 25% of final energy use in the heating sector, of which over two-thirds was traditional biomass. Modern renewable energy supplied the remaining third, or about 8% of the world's total final energy use for heat production.
All of which helped the world achieve a sustainable development milestone: In 2014, for the first time in four decades, the world economy grew without a parallel rise in carbon dioxide emissions. Despite the world's annual 1.5% increase in energy consumption in recent years and 3% Gross Domestic Product growth last year, CO2 emissions were unchanged from 2013 levels: 32.3 billion metric tons.
According to the report, the landmark "decoupling" of economic and CO2 growth is due in large measure to China's increased use of renewable resources, and efforts by countries in the Organisation for Economic Co-operation and Development to promote sustainable energy sources.
This is "particularly encouraging," the report says, given the UN's major conference in December in Paris, where countries will announce and / or confirm actions to mitigate climate change, setting the stage for future investment in renewables and energy efficiency. "Renewable energy and improved energy efficiency are key to limiting global warming to two degrees Celsius and avoiding dangerous climate change", says REN21 Chair Arthouros Zervos, who released the new report at the Vienna Energy Forum.
Employment in the sector is growing fast as well. In 2014, an estimated 7.7 million people worldwide worked directly or indirectly in the renewable energy sector
The sector's growth could even greater if not for government policies, including more than $550 billion in annual subsidies for fossil fuel and nuclear energy, which perpetuate artificially low energy prices from those sources, encouraging waste and impeding competition from renewables.
Says Christine Lins, Executive Secretary, REN21: "Creating a level playing field would strengthen the development and use of energy efficiency and renewable energy technologies. Removing fossil-fuel and hidden nuclear subsidies globally would make it evident that renewables are the cheapest energy option."
More than one billion people, or 15% of humanity, still lack access to electricity. With installed capacity of roughly 147 GW, all of Africa has less power generation capacity than Germany. Distributed renewable energy technologies are improving the situation, providing essential and productive energy services in remote and rural areas. For example, off-grid solar PV (which attracted roughly US $64 billion in 2014) has a significant and growing market presence.
However, the growth rate is below that necessary to achieve the Sustainable Energy for All (SE4ALL) goals of doubling renewable energy and energy efficiency and providing universal access for all by 2030.

Other report highlights
New investment in renewable power and fuels (not including hydropower >50 MW) increased worldwide by 17% over 2013, to US$ 270.2 billion. Including large-scale hydropower, new investment in renewable power and fuels reached over US$ 301 billion.
Global new investment in renewable power capacity was more than twice that of investment in net fossil fuel power capacity, continuing the trend of renewables outpacing fossil fuels in net investment for the fifth year running.
Investment in developing countries was up 36% from the previous year to US$ 131.3 billion. Developing country investment came the closest ever to surpassing the investment total for developed economies, which reached US$ 138.9 billion in 2014, up only 3% from 2013.
China accounted for 63% of developing country investment, while Chile, Indonesia, Kenya, Mexico, South Africa and Turkey each invested more than US$ 1 billion in renewable energy.
By dollars spent, the leading countries for investment were China, the United States, Japan, the United Kingdom and Germany. Leading countries for investments relative to per capita GDP were Burundi, Kenya, Honduras, Jordan, and Uruguay.
- Wind: The growth of energy generated with wind turbines resumed in 2014, which marked another record year.
Over 51 GW of wind capacity was added, representing a 44% increase over 2013 and raising the world total to around 370 GW. China alone accounted for 45% of global additions. Asia remained the largest market for the seventh consecutive year, and overtook Europe in total capacity. However, Europe saw its second highest installations ever, largely thanks to Germany. The United States was the leading country for wind power generation.
Wind power met more than 20% of electricity demand in several countries--including Denmark, Nicaragua, Portugal, and Spain. An estimated 1.7 GW of grid-connected capacity was added offshore-- all in the United Kingdom, Germany, Belgium, and China -- bringing the world total to more than 8.5 GW.
- Solar PV: Rapidly falling costs have made unsubsidized solar-generated electricity more cost-competitive, fuelling the record-breaking 40 GW added capacity installed in 2014, raising total global capacity to 177 GW. The top three PV markets, China, Japan, and the United States, accounted for the vast majority of new capacity. Latin America is the fastest growing regional market. Significant new capacity also came online in several African countries, and markets are picking up in the Middle East. Consolidation among solar technology manufacturers continued, although the flood of bankruptcies seen over the past few years slowed to a trickle.
- Hydropower: An estimated 37 GW of new hydropower capacity was commissioned in 2014, raising the global total to approximately 1,055 GW. By far, the most new capacity was installed in China (22 GW), with significant capacity also added in Brazil, Canada, Turkey, India, and Russia.
- Concentrated Solar Thermal Power: CSP continued a near decade-long run of strong growth in 2014, with total global capacity up 27% to 4.4 GW. Only the United States and India added CSP facilities to their grids in 2014. However, CSP activity continued in most regions, with South Africa and Morocco as the most active markets in terms of construction and planning. Spain remained the global leader in terms of existing capacity. Spain added no new capacity in 2014 due to regulatory curtailment of the Spanish CSP industry, but remained the global leader in terms of existing capacity (2.3 GW).
- Bioenergy: Bio-heat capacity increased by an estimated 3% in 2014. Composition of bio-heat portfolios continued to vary widely by region, ranging from large-scale production in industry (e.g., in the United States) to vast numbers of residential-scale bio-digesters (e.g., in China). Global bio-power production increased approximately 9%, with China, Brazil and Japan leading for capacity additions, and the United States and Germany leading for generation (despite comparatively smaller capacity additions).
Liquid biofuel production was up 9% in 2014, reaching its highest level to date. Although the United States and Brazil dominated overall volume, Asia experienced particularly high growth rates of production. Biofuels production also increased in Europe, although growth was slowed by the decision to limiting the contribution of first generation biofuels to EU national targets. Low oil prices in the second half of the year positively affected some feedstock production, but reduced turnover for some bioenergy businesses.
Trade patterns in both solid and liquid fuels saw some shifts in 2014, with a considerable share of North American wood pellets flowing to Asia, reducing the domination of flows to European markets. The share of traded biofuels destined for Europe continued to decline, while new markets (particularly for fuel ethanol) expanded in other regions.
- Solar Thermal Heating and Cooling: Deployment of solar thermal technologies continued to slow, due largely to declining markets in Europe and China. Cumulative capacity of water collectors reached an estimated 406 GWth by the end of 2014 (with air collectors adding another 2 GWth), providing approximately 341 TWh of heat annually. China again accounted for about 80% of the world market for solar water collectors, followed by Turkey, Brazil, India and Germany.
- Geothermal: About 640 MW of new geothermal power generating capacity came online in 2014 bringing total global capacity close to 12.8 GW. Total capacity growth has averaged 3.6% for the last five years. The largest share of new geothermal power capacity came on line in Kenya.
- Ocean Energy: Harnessing mostly tidal but also some wave energy, generation remained at about 530 MW in 2014. Virtually all new installations were in some form of pilot or demonstration projects.
- Energy efficiency: Overall, energy intensity has decreased in most regions, with the exception of the Middle East. In a growing number of countries, policies have been enacted to improve the energy efficiency of buildings, appliances, industry and transport vehicles, including fuel economy standards, incentives for electric (EV) and hybrid (HEV) vehicles, and public transit.
- A trend towards meeting transportation and heating needs with electricity continued in 2014.
Recommendations, in brief
- Develop stable and predictable policies that can adapt to a changing environment
- Showcase and communicate renewables ability to provide industrial-scale electricity supply
- Create a level playing field to increase cost-competiveness beyond PV and wind
- Renewable power: energy system thinking is required
- Increase support to the renewable heating and cooling sector
- Improve access to finance in developing countries
- Drive good decisions with good data
