Energy Efficiency

HEDON (Household Energy Network)

HEDON Household Energy Network is the leading knowledge sharing and networking NGO for household energy solutions in developing countries. HEDON focuses on sustainable energy at household and community level, to improve the lives of people living in poverty while protecting the natural environment and combating climate change. HEDON informs and enables the work of its members through information sharing, learning, networking, and facilitation of partnerships. It also contains various embedded tools, a technology wiki, and discussion forums.

Geospatial Toolkit (NREL)

The Geospatial Toolkit (GsT) is an NREL-developed map-based software application that integrates resource data and other geographic information systems (GIS) data for integrated resource assessment. The non-resource, country-specific data for each GsT comes from a variety of agencies within each country as well as from global datasets. Users will find the GsT helpful in identifying the most economically viable areas for deployment of renewable energy technologies.  

ESMAP Low Carbon Growth Country Studies

ESMAP’s Low Carbon Growth Studies Pilot Project (2007–09), the governments of six middle-income-countries—Brazil, China, India, Indonesia, Mexico, and South Africa—assessed their development goals and priorities for GHG mitigation. The studies considered the additional costs and benefits of lower carbon growth and how to finance such measures. There is no single approach to the Low Carbon Growth Country Studies. Each study is determined by the country—government and local stakeholders—and tailored to the country’s economic circumstances.

Improving the Effectiveness of Climate Finance: Key lessons (EDF)

This paper (PDF) presents an overview of existing practices by summarizing the findings from an extensive survey of various institutions, drawing on the lessons learned from development finance, the public and private activities of international financial institutions and experience with market-based instruments. The paper mainly focuses on mitigation, and it seeks to discern lessons for policymakers by addressing two key questions: What makes climate finance effective? and what tools, methods or systems might improve the effectiveness of climate finance?  


This web-based programme allows technical and non-technical users alike to visualise the effects of climate change. Users can view historic temperature and rainfall maps overlaid with predictions of temperature and rainfall based on the Intergovernmental Panel on Climate Change’s (IPCC) Fourth Assessment Report. Users can review three greenhouse gas emission scenarios laid out by the IPCC with additional data layers from which more detailed forecasts can be drawn. ClimateWizard was developed by the Nature Conservancy and the Universities of Washington and Southern Mississippi.

The Landscape of Climate Finance

In this paper, the Climate Policy Initiative (CPI) assesses the current status of the climate finance landscape, mapping its magnitude and nature along the life cycle of finance flows, i.e. the sources of finance, intermediaries involved in distribution, financial instruments, and final uses. After presenting estimates of current flows based on available data, describing the methodology, and discussing the sources of data, we offer recommendations to improve further data-gathering efforts.  

Investment-grade Climate Change Policy: Financing the transition to a low-carbon economy

The report has two objectives: (1) to contribute to policymakers’ understanding of the factors that institutional investors consider when investing in areas such as renewable energy and energy efficiency, and (2) to set out what institutional investors see as ‘investment-grade’ climate change and clean energy policy that would support significant low carbon, clean energy investment. 

Mobilising Private Finance for Low-Carbon Development

The public sector will have to leverage several hundreds of USD billions of private investments per year in order to enable low-carbon development limiting global warming to 2 degrees Celsius. The authors of this report have studied different tools for leveraging funds, ways to accounting for private funds, and finally whether the ratio of leveraged private funds to leveraging public funds is a good indicator for efficiency.
