Unraveling Urban Household Energy Use Patterns in India

CLASP published a research paper in the ACEEE 2020 Summer Study on Energy Efficiency in Buildings in India. The paper reviews first-of-its-kind nationwide research, carried out in 2018, that encompassed an urban residential end-use survey of 5,000 households and real-time appliance energy use monitoring of 200 households.

Quantifying Lighting Benefits under the RoHS Directive: Calculating the Cost of Lost Time

CLASP recalculated the effects of the Oeko-Institut data for a one-year, two-year or three-year delay, showing significant costs to European citizens in terms of excess energy use, increased pollution, and higher cost to consumers.

Off-Grid Appliance Market Survey 2020

The 2020 Off-Grid Appliance Market Survey shares key insights on the perceived demand for, and impact of, off-grid appropriate appliances using data collected from 133 industry, policy, and development stakeholders. The survey results reflect the dynamic needs of off-grid consumers and aim to characterize the positive socioeconomic impact of a range of household appliances, productive use equipment, and healthcare technologies.

Clarifications on Lighting Europe’s Comments to the RoHS Committee

This report is the third in a series of market and technology studies that consider whether the exemptions for fluorescent lighting should be continued or retired. The report was developed to address issues that were raised by Lighting Europe in two sets of comments they submitted directly to the RoHS Committee and the Commission.

Finding the Sweet Spot: Identifying Affordable Quality Solar Products for the Last Mile

This report brings together the GDC’s findings from 6 months of research on the quality of best-selling non-quality-verified (non-QV) products in Kenya. Through a funnelled field survey and quality testing led by VeraSol, our research identified non-QV products that are close to meeting the Lighting Global Quality Standards while remaining highly price-competitive with leading products in the market today.

Indonesia Residential End-Use Survey

CLASP and Ipsos conducted a first-of-its-kind national survey of household appliance use in Indonesia to provide insights into appliance ownership and usage at the household level to support energy efficiency policies that maximize energy and CO₂ reductions and cost savings for household consumers, manufacturers, and the nation.

Indonesia Market Study and Policy Analysis for Lighting

CLASP, in partnership with PwC, conducted a comprehensive study of lighting products in Indonesia in efforts to characterize the market; inform the development of appropriate and robust fans testing, standards, and labeling requirements; and assess the potential impacts of these energy efficiency policies.

Bulk Procurement Inspection Manuals

In November 2019, Energy Efficiency Services Limited (EESL), an energy service company set up under India’s Ministry of Power, published a series of inspection manuals to guide bulk procurements for five product categories: electric motors, LED street light fixtures, room air conditioners, smart meters, and submersible water pumps.

Assessing Annex III Fluorescent Lamp Exemptions in the Light of Scientific and Technical Progress

This report provides a technical assessment of the exemptions provided in Annex III of the Directive 2011/65/EU of the European Parliament and of the Council of 8 June 2011 on the restriction of the use of certain hazardous substances (RoHS) in electrical and electronic equipment for fluorescent lamp types.

Residential End-Use Energy Consumption and Appliance Ownership Patterns in India

In 2019, CLASP worked with Environmental Design Solutions to conduct a first of its kind pan-India urban residential end-use survey and real-time appliance energy-use monitoring through Non-intrusive Load Monitoring (NILM). The study’s objective was to establish appliance ownership and usage patterns for urban households and develop a framework for data collection and analysis on energy end-use.

Evaluating the Impacts of Mandatory Policies and Labelling Program for Appliances in India

This paper discusses the impacts of mandatory standards and India's labelling program as they relate to market growth, technology improvements, market transformation, and climate change mitigation.

Evaluating Appliance Ownership and Usage Patterns in India

In 2019, CLASP worked with Environmental Design Solutions to conduct a first-of-its-kind pan-India urban residential end-use survey. The study evaluated appliance ownership and usage patterns for urban households and aimed to develop a framework for future data collection and analysis.

Mercury-Free Alternatives to Certain Fluorescent Lamps: A Report to the European Commission’s Committee on the Restriction of Hazardous Substances

The Swedish Energy Agency and CLASP conducted a market and technology review to examine the availability of mercury-free lighting products to replace T5 and T8 linear fluorescent lamps and compact fluorescent lamps which are not integrally ballasted (CFLni).

SEAD Global Appliance Testing Costs Catalogue

Off-Grid Appliance Market Survey 2018

The 2018 Off-Grid Appliance Market Survey report examines the perceived demand and impact potential of household, productive use and healthcare technologies.

Quality Matters

Lighting Global Quality assurance tested a group of top-selling non-quality verified solar products in five domestic markets across Africa and South Asia. All 17 evaluated products failed to meet the Lighting Global Quality Standards for pico-PV products.

Off- and Weak-Grid Appliance & Equipment Technology Summaries

This document is a summary and distillation of CLASP’s research into appliances for which the demand is strong, but which are only available in low volumes and at relative­ly high cost. The summary also identifies early stage technologies which may be disruptive to existing dominant appli­ances.
