Energy Technology Perspectives 2015

ETP 2015 book cover thumbnailAs climate negotiators work towards a deal that would limit the increase in global temperatures, interest is growing in the essential role technology innovation can and must play in enabling the transition to a low-carbon energy system. Indeed, recent success stories clearly indicate that there is significant and untapped potential for accelerating innovation in clean technologies if proper policy frameworks are in place.

In an especially timely analysis, the 2015 edition of Energy Technology Perspectives (ETP 2015) examines innovation in the energy technology sector and seeks to increase confidence in the feasibility of achieving short- and long-term climate change mitigation targets through effective research, development, demonstration and deployment (RDD&D). ETP 2015 identifies regulatory strategies and co‑operative frameworks to advance innovation in areas like variable renewables, carbon capture and storage, and energy-intensive industrial sectors. The report also shows how emerging economies, and China in particular, can foster a low-carbon transition through innovation in energy technologies and policy. Finally, ETP 2015 features the IEA annual Tracking Clean Energy Progress report, which this year shows that efforts to decarbonise the global energy sector are lagging further behind.

By setting out pathways to a sustainable energy future and by incorporating detailed and transparent quantitative modelling analysis and well-rounded commentary, ETP 2015 and its series of related publications are required reading for experts in the energy field, policy makers and heads of governments, as well as business leaders and investors.

Energy Technology Perspectives 2014 - Harnessing Electricity's Potential

energy technology in ETP 2014Energy Technology Perspectives sits at the heart of the International Energy Agency's work on energy technology and policy. It offers a comprehensive, long-term analysis of trends in the energy sector - and of the technologies that are essential to achieving an affordable, secure and low-carbon system.  

Starting from the premise that electricity will be an increasingly important vector in energy systems of the future, Energy Technology Perspectives 2014 (ETP 2014) takes a deep dive into actions needed to support deployment of sustainable options for generation, distribution and end-use consumption. 

Clean energy through technology

In addition to modelling the global outlook to 2050 under different scenarios, ETP 2014 incorporates the IEA's annual progress report on global efforts to engineer a clean-energy transformation. Moreover, ETP 2014 provides insight on many key questions about the future energy system, including:

  • How much will the transformation to a clean-energy system cost?
  • Is solar the answer to decarbonising the electricity supply?
  • How can technologies help continue to exploit the advantages of natural gas in a decarbonised energy system? 
  • Can electrification have a meaningful impact on transportation, and if so, how?
  • Is energy storage the game changer that many want to believe?
  • What will it take to reach high-efficiency power generation in India? 

Energy and technology guidance for the past decade

Since it was first published in 2006, Energy Technology Perspectives has evolved into a series that sets out pathways to a sustainable energy future in which optimal technology choices in energy production are driven by cost, energy security and environmental factors. .

Tracking Clean Energy Progress 2014

energy technology in ETP 2014Tracking Clean Energy Progress 2014 examines progress in the development and deployment of key clean energy technologies. This Energy Technology Perspectives 2014 (ETP 2014) excerpt tracks each technology and sector against interim 2025 targets in the IEA 2014 Energy Technology Perspectives 2°C scenario, which lays out pathways to a sustainable energy system in 2050.

Deployment of solar photovoltaics (PV), onshore wind and electric vehicles (EVs) is still increasing rapidly, but their growth rates are slowing. Growth of coal-fired power generation exceeds that of all non-fossil fuels combined. Nuclear power generation is stagnating. Development of carbon capture and storage (CCS) remains too slow. These trends reflect inadequate political and financial commitment to long-term sustainability of the global energy system.

Tracking Clean Energy Progress 2014 provides, together with ETP 2014, specific recommendations to governments on how to scale up deployment of these key technologies toward a secure, clean and competitive energy future.

More Data, Less Energy

More Data, Less Energy cover‌The global electricity demand of information communication technology has reached 8% of total final electricity consumption.  This demand is increasing at a much more rapid rate than overall electricity demand.  More than a third of this electricity is used by devices connected to networks in homes and offices.  Most of this electricity is used not to perform any function, but simply being alert in case a signal from the network arrives. 

More Data, Less Energy: Making Network Standby More Efficient in Billions of Connected Devices looks at the rapidly increasing connectivity in a broad range of products, exploring how "everything is becoming smart" and "network-enabled". While consumers are devouring this new convenience and the extra functionality provided by network-enabled devices, the energy waste implications are big and getting bigger.  The book provides an overview of technology and policy options to improve the energy efficiency of network-enabled devices.  ‌

Transition to Sustainable Buildings

Transition to Sustainable Buildings Buildings are the largest energy consuming sector in the world, and account for over one-third of total final energy consumption and an equally important source of carbon dioxide (CO₂) emissions. Achieving significant energy and emissions reduction in the buildings sector is a challenging but achievable policy goal.

Transition to Sustainable Buildings presents detailed scenarios and strategies to 2050, and demonstrates how to reach deep energy and emissions reduction through a combination of best available technologies and intelligent public policy.
