Reducing Greenhouse Gas Emissions through Energy Efficiency – and Learning from One’s Peers

MD Staff



China, India, Indonesia, the Philippines, Pakistan, and Vietnam are critical for global climate action. Why? Among other reasons, because three-fourths of all new coal-fired power plants to begin operations before 2020 globally will be in these six Asian countries. Fostering more energy efficiency will be imperative in the countries’ efforts to adopt a low carbon energy path.

One initiative that supports efforts to scale up energy efficiency and clean energy – and lower greenhouse gas emissions – in these six countries is the Energy Transition in Asia program managed by the Energy and Extractives Global Practice.

Comprising of knowledge exchange and capacity building on key issues, the program recently held a workshop in Singapore to share lessons learned on energy efficiency, following last year’s learning forum on solar auctions, also held in the city-state. Participants agree that peer-to-peer learning works. After sharing best practice efforts in China, India, Japan, Korea, Mexico, the United Kingdom, and host country Singapore, team spirit and friendships strengthened, along with confidence, productivity and learning outcomes.

By the end of the three-day workshop, participants from governments not only requested follow-up assistance but also to learn more from their newfound friends about conserving more energy. “We were able to advance country engagement with the clients on energy efficiency,” explained Xiaodong Wang, team leader for the Energy Transition in Asia initiative. “Conducive policies that combine mandatory regulations with financial incentives are essential drivers to create market demand for catalyzing investments in energy efficiency.”

Results are already encouraging. China is a leading example. From 1990 to 2010, more than half of global energy savings took place in China, thanks to the government’s ambitious targets, stringent regulatory policies, generous financial incentives, and effective institutions – all of which reiterate strong commitment to energy efficiency. Reducing energy intensity was made a mandatory target, allocated to each province and 17,000 energy intensive enterprises. Efficiency standards for appliances, buildings, and vehicles were upgraded and complemented with billions of dollars of financial incentives in output-based subsidies, rebates for energy efficient consumer products, and compensation for the phase-out of inefficient stocks. All these efforts were monitored across the country.

India also led by example. Energy savings targets – at least for energy intensive industries – were made mandatory with the Perform, Achieve, and Trade scheme (PAT), which also allows the trade of Energy Savings Certificates to achieve targets in a least-cost way. Non-compliance at the end of the three-year cycle incurs a financial penalty. The results of the first phase surpassed targets. The second phase began in April 2017.

Workshop participants from India reminded, however, that these are early years. Following a visit to the district cooling system under Marina Bay Sands – the world’s largest underground facility and its most efficient – S.P. Garnaik, Chief General Manager of India’s Energy Efficiency Services Ltd. (EESL), a joint venture under the Ministry of Power, envisioned replicating such a system in India. But while a policy framework is being prepared to support the use of district cooling systems in rapidly urbanizing India, Garnaik admits that substantial results may take time, as “these are very new concepts.”

In addition to the mandatory output-based target approach in China and India, participants also noted Singapore’s green mark program, which combines mandatory building codes with financial incentives from the government for auditing and investment costs, as a model to emulate.

Indeed, the knowledge gap between participating countries is large. Yet even countries in the ‘nascent’ phase are eager to make progress.

Energy intensity in Asia is highest in Vietnam, with energy consumption by industry accounting for almost half of the country’s total energy use. Current efforts towards energy efficiency are encouraging. Labeling schemes have been established and energy management systems now require energy managers and auditors in large energy users. Indonesia is implementing a similar  system.

Learning from one’s peers can be galvanizing. As Trinh Quoc Vu of Vietnam’s Energy Efficiency and Sustainable Development Department at the Ministry of Industry and Trade explains, Vietnam is eager to learn from China’s and India’s shift to a mandatory target approach. Indonesia’s delegates were inspired by their peers’ experience in expanding pilot programs. The Bank is providing advisory services to both Indonesia and Vietnam in their efforts to scale up energy efficiency.

The workshop also highlighted the critical role of strong government support in developing the ESCO business. ESCOS are energy service companies which design and implement energy savings projects.  Energized by his peers, Trinh is now intent on exploring mechanisms for promoting and incentivizing the ESCO business in Vietnam.

The World Bank Group supports many energy efficiency financing mechanisms worldwide, including through credit lines, risk sharing facilities, dedicated funds, program-for-results (PforR), and development policy loans. Critical to success is a strong pipeline for deal flows, as well as technical assistance.

In India, the Partial Risk Sharing Facility for Energy Efficiency initiative, financed by the Clean Technology Fund (CTF) and Global Environment Facility (GEF) resources,  is supporting private sector ESCO-implemented energy efficiency projects through partial credit guarantees. The proposed new US$300 million India Energy Efficiency Scale Up Operation with EESL is expected to leverage over $1.5 billion of demand side energy efficiency investments across residential and public sectors. Similarly, the China Energy Efficiency Financing Project has leveraged the original World Bank financing eight times over, with a total investment of US$2.6 billion. The project has led to an annual reduction of 11 million tons of CO2 emissions.

Such figures may seem ambitious, but workshop participants were unfazed. Many are confident they will accomplish similar achievements. When learning from one’s peers, who all face challenges in their respective development journey, anything can seem possible.

Economic value of energy efficiency can drive reductions in global CO2 emissions

MD Staff



Ambitious energy efficiency policies can keep global energy demand and energy-related carbon-dioxide (CO₂) emissions steady until 2050, according to a new report by the International Energy Agency. Perspectives for the Energy Transition: The Role of Energy Efficiency shows that despite a near-tripling of the world economy and a global population that increases by nearly 2.3 billion, end-use energy efficiency alone can deliver 35% of the cumulative CO₂ savings through 2050 required to meet global climate goals.

Global energy demand grew by 2.1% in 2017 according to IEA estimates, more than twice the growth rate in 2016. At the same time, global energy-related CO₂ emissions increased for the first time in three years, as improvements in global energy efficiency slowed down dramatically to 1.7%.

“Among all energy trends in 2017, the one that worries me the most is the slowdown in energy efficiency improvements,” said Dr Fatih Birol, Executive Director of the International Energy Agency. “The rate of improvement that we saw is around half of the rate that is required to meet clean energy transition goals.”

IEA analysis in Perspectives for the Energy Transition: The Role of Energy Efficiency demonstrates that on top of a wide range of benefits including cleaner air, energy security, productivity and trade balance improvements, there is a compelling economic case for energy efficiency. But, without further policy efforts, these benefits are unlikely to be realised as less than a third of global final energy demand is covered by efficiency standards today.

Realising the full potential of energy efficiency will require a step-change in investments on the demand side of the energy equation, rising to USD 1.7 trillion per year through 2050, the majority of which is for energy efficiency and the electrification of transport. On the supply side, the focus is on reallocating investments towards renewables and other low-carbon technologies such as nuclear and carbon capture, utilisation and storage.

While the scale of the demand-side investment required may appear challenging, fuel cost savings over the lifetime of most technologies are larger than the investment required, which implies a strong economic benefit that arises from energy efficiency investment. Although there are still many low-hanging fruits that can pay back their initial investment quickly, payback periods are often too long to attract investment from consumers and businesses. Effective policy frameworks are needed to overcome economic and non-economic barriers to energy efficiency and to incentivise adoption of more efficient technologies.

Perspectives for the Energy Transition: The Role of Energy Efficiency demonstrates a compelling economic case for energy efficiency as being essential to make the energy transition affordable, faster and more beneficial to all. The IEA recommends that governments adopt a strategic approach to energy efficiency, supported by well-designed efficiency policies and a strong focus on implementation and enforcement.

Report: Powerful New Policy Options to Scale Up Renewables

MD Staff



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.

Key areas of focus:

Heating and Cooling

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.

Power sector

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.

System integration

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.

Better information needed to improve gender diversity in the clean-energy sector

MD Staff

Recognizing that the energy sector lags when it comes to gender diversity, the Italian Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) and the International Energy Agency (IEA) brought together over 80 experts from governments, industry, academia and other organisations for a day-long workshop last week to discuss ways to improve data on women’s participation in the clean-energy sector.

Only limited data on the participation of women in the energy sector is currently available – data that will be critical to building a better understanding of how to make the sector more gender balanced. Without better information, reaching the goal of gender equality by 2030, set under the United Nations Sustainable Development Goal (SDG 5), will be impossible to reach.

Participants shared experiences on data collection and methods of assessment to analyse gender diversity as well as employment opportunities offered to women by the clean energy transition. The workshop was held under the Clean Energy Education and Empowerment Technology Collaboration Programme (also known as the C3E TCP), which seeks to promote higher participation of women in the clean-energy sector.

“The extraordinary and recognised capacity of women to handle complex and multivariable contexts, their openness to innovation and their responsiveness to environmental issues constitute an important asset for the energy transition” said Massimo Gaiani, Director General for Global Affairs of the Italian Ministry of Foreign Affairs and International Cooperation.

Four key messages emerged from the discussions:

1)    Participants recognised the importance of collecting more detailed gender disaggregated data, but stressed the need to clearly define what information was needed and why;

2)    Quantitative data should be supplemented with qualitative information to identify key barriers for women pursuing careers in the energy sector and to develop more targeted solutions to overcoming these challenges;

3)    While comprehensive data is limited, a significant number of national and international efforts to collect information and promote gender already exist and there is opportunity for the Clean Energy Education and Empowerment Technology Collaboration Programme (C3E TCP) to collaborate with other leading institutions working on gender diversity to help build and disseminate knowledge;

4)    Finally, the increased engagement of men to promote and support women’s advancement into leadership roles is critical in meeting gender equity and should be fostered.

The meeting also included a dialogue with leading Italian energy companies on a proposal to adopt a common pledge to take action and commitments to achieve gender equality by 2030 (SDG 5). Led by Sweden and Canada with support from the IEA, this new campaign will be launched at a side event to take place at the next Clean Energy Ministerial meeting in Copenhagen on 24 May.

Companies recognised the valuable role that women play in driving innovation and sustainability. Francesca Magliulo, Head of Sustainability and Corporate Social Responsibility of EDISON S.p.A Italy said, “Edison supports this initiative, our experience shows that inclusion and gender diversity creates new capacity to offer innovative solutions to new markets and new customer communities.”

Participants also confirmed that the current momentum to advance and accelerate progress on gender equality represents a tremendous opportunity. While the workshop focused on building knowledge and improving data, Elisabeth Marawba of the Department of Energy of South Africa stressed that “we also need to pay attention to the empowerment of women as business-owners and investors and not just focus on the employment aspects of women in clean energy.”

The C3E TCP and IEA will work together to expand data and indicators as well as undertake analysis to help fill the knowledge gap on gender diversity and women’s empowerment in the energy sector.
