Energy Efficiency 2018
…current technology. This delayed action on energy efficiency ends up locking in inefficiencies that mean much stronger action needs to be taken in the future. 2.2 million barrels of oil per day If all countries had adopted the best passenger fuel economy standards. 16% of industry electricity use If all countries had adopted the strongest electric motor standards. $20 billion If everyone had purchased the top 10% most efficient refrigerators. The Efficient World Scenario So what will the world look like if between now and 2040 countries implemented all the economically viable energy efficiency potential that is available? The…

Energy Efficiency Outlook for India: Sizing up the opportunity
This report was produced as part of the Energy Efficiency in Emerging Economies (E4) Programme which is managed by the Energy Efficiency Division of the IEA.This analysis aims to inform government, businesses and other stakeholders about the prospects for energy use in India and the role that energy efficiency improvements offer in the period to 2040. It quantifies the potential energy savings and related CO2 emission reductions, and the associated costs and benefits of policies aimed at exploiting that potential. The report also includes energy efficiency policy recommendations for each sector covered.

E4 Country Profile: Energy Efficiency in India
…scheme, the key policy driving efficiency gains in the industrial sector. The adoption of appliance standards and building codes in some states, coupled with growing energy access and new construction, resulted in policy coverage in the buildings sector of 13% in 2018. In the transport sector, the implementation of passenger car and heavy-duty vehicle standards increased the policy coverage to 6% in 2018. Ambitious plans have also been developed to increase the penetration of electric vehicles. Energy efficiency opportunities Under the Efficient World Scenario, the increase in energy demand could be limited to just 82% between now and 2040…

Railway Handbook 2015
…the Railway Handbook 2015. For this edition, significant methodological improvements were implemented leading to better consistency between the different indicators presented in this Handbook, in addition to updates of the global data, as well as regional breakdowns for those regions that we consider the most relevant from the point of view of transport activity: European Union, USA, Japan, Russia, India, and China. This edition devotes particular attention to the energy efficiency of rail vehicles. This is achieved by providing information on the energy efficiency of trains in different world regions, with a richer set of indicators for the European Union.

Efficient Grid-Interactive Buildings in India
…and variable supply could jeopardise grid stability and increase system costs. EGIBs offer an important solution for optimising electricity use, reducing peak demand and enhancing system flexibility.Applying a structured framework, this report assesses India’s policy landscape and opportunities across efficiency, decarbonisation, smartness, resilience, materials and building-to-grid interaction. It concludes with recommendations for a comprehensive policy package that encompasses regulations, incentives and information. Scaling up the adoption of efficient grid-interactive buildings would enable India to align its fast-growing building stock with national climate goals and international commitments while lowering system costs and enhancing energy security.

Boosting Efficiency in Latin America
…While much attention focuses on securing energy supplies, it is equally important to take a hard look at the role of more efficient and flexible demand in securing affordable, reliable energy. There are several reasons for this. First, one of the fastest and cheapest options for short-term emergency situations is to reduce demand. Second, investments in more efficient technologies and practices can reduce risk over time while improving access to energy services, saving money and supporting efficient, less costly energy systems. Third, managing demand by improving efficiency and making loads more flexible is key to cost-effectively meeting decarbonisation…

India Energy Outlook 2021
…further growth in energy demand and infrastructure is huge India is the world’s third-largest energy consuming country, thanks to rising incomes and improving standards of living. Energy use has doubled since 2000, with 80% of demand still being met by coal, oil and solid biomass. On a per capita basis, India’s energy use and emissions are less than half the world average, as are other key indicators such as vehicle ownership, steel and cement output. As India recovers from a Covid-induced slump in 2020, it is re-entering a very dynamic period in its energy development…

…even amid considerable volatility in commodity prices. These developments have intensified the scrutiny on the returns associated with the Indian RE sector. To shed light on these matters, the Clean Energy Investment Trends 2021 report analyses project-level equity returns expectations associated with plain vanilla assets over the period July 2020 - June 2021 as well those corresponding to select hybrid projects. It endeavours to contextualise these returns expectations by comparing them with those in other geographies and examines their sensitivities to solar photovoltaic (PV) module prices, which are now subject to increased volatility. The report also examines land-related challenges…
