The Renewable Energy and Energy Efficiency Partnership (REEEP) is an active, global partnership that works to reduce the barriers limiting the uptake of renewable energy and energy efficiency technologies, with a primary focus on emerging markets and developing countries.

Supported technologies

© Climate Tech Wiki - acc and respective owners Ocean energy: Tidal stream

Marine renewables, also known as ocean energy, refers to a broad range of technologies that extract energy from the ocean; this energy can be in the form of ocean waves, tidal movements or thermal gradients.  Marine renewables are, in general, at a relatively early stage in their development and, as such, the methods of converting these potential energy sources into useful electrical power are still highly diversified, with many technologies competing for commercial viability.

Molten Carbonate Fuel Cell in a T-Mobile data center in Munich Fuel cells for stationary applications

Fuel cells make it possible to efficiently convert the energy stored in several kinds of gases, among which hydrogen and methane, into electricity. Although the concept, according to which fuel cells operate, was already discovered in 1839 by William Grove, the first development only started in 1932 through Francis Bacon’s exploratory work. It was only in the early 1960s that significant efforts were put into fuel cell development, when NASA decided that fuel cells were to become the principal replacement for batteries in spacecraft (Bacon, 1969 and Schoots et al., 2010).

Videocon Refrigerator, 3 Star Indian BEE rating Energy efficient refrigerators

Refrigerators are used in households across the world to store food at a temperature of about 3 to 5 °C (37 to 41 °F) in order prevent it from spoiling. This technology description focuses on refrigerators for residential use and on energy efficiency performance only. It does not take into account potential GHG effects caused by the refrigerant.

Flame in a glass furnace (ICG, 2010) Increased glass recycling

Over half of the energy consumption of the glass industry is used for melting in order to form the glass. Adding recycled glass to the raw materials reduces energy use and CO2 emissions. Another advantage is that less raw material is needed. Currently, the world-average glass recycling rate is about 50%. Higher recycling rates are possible, especially in regions where the recovery rate is still low.

QAFCO ammonia plant at Mesaieed (Qatar Petroleum) Fuel switch in the ammonia industry

Ammonia is the main product of the fertilizer industry. Developing countries account for the majority of worldwide production. About 77% of ammonia production is based on steam reforming of natural gas, with most of the remaining production based on heavy-oil or coal-based processes.  A further shift from heavy-oil or coal-based to gas-based processes can strongly reduce energy use and emissions.

Technology policy and financial support

6th Inter-Parliamentary Meeting on Renewable Energy and Energy Efficiency

To assist parliamentarians with coherent, coordinated and comprehensive strategies/guidance for renewable energy and energy efficiency policy at the EU and international level, including strategies against problems such as oil price volatility, import dependency on energy products, increasing energy demand, development policy, environmental policy and agricultural policy.

Amazonia Energy Initiative (Energia da Amazonia)

To design and start the Amazonia Energy Initiative (AEI) aimed at increasing energy access for isolated communities in the Amazon region while promoting productive and efficient energy use.

Breaking the risk barrier for institutional investment in clean energy in emerging markets

To attract institutional financing for renewable energy and energy efficiency enterprises in the emerging markets by developing risk mitigation strategies and financing products through intermediaries such as E+Co. 

Cap and trade scheme for the Mexican auto industry

To provide Mexico's National Institute of Ecology (INE) with a comprehensive economic analysis of its proposed cap and trade scheme for the Mexican automobile industry.

Capacity Building Support for the Implementation of the Renewable Energy Law in China

To support the Government of China to implement the Renewable Energy Law, which came into force in January 2006.

Carbon financing for energy efficiency in Indian SME clusters

To work with one SME cluster as a pilot, involving its local trade association or Chamber of Commerce and the Indian Renewable Energy Development Agency (IREDA) to explore options for financing energy efficiency equipment by pooling the cluster's demand and using a carbon financing mechanism, and then to disseminate this model to other nearby clusters.

China roadmap for 30% renewable energy penetration by 2030

To undertake the preliminary research on the role that RE could have for China by 2030, underpinning a specific RE target such as 30% with a deep analysis of economic development targets, energy resource availability, and environmental factors, as a sound reference for government policymaking.

Clean energy policy and regulation in Tonga

To strengthen the regulatory capacity of the Energy Division (ED) of the Ministry of Lands, Survey, Natural Resources (MLSNR) in Tonga, helping  to operationalise the Renewable Energy Bill of 2008, which is awaiting royal assent, and to assist in the drafting of an energy efficiency (EE) policy, setting the stage for the drafting of an EE Bill.

Cornucopia hybrid finance for renewable energy in agriculture

To demonstrate the value of renewable energy financing as a significant new tool for rural economic development, by using solar water pumps, solar dryers, and biodigestors to help farmers produce high-value products for local and national markets.

Creating a Link between Energy Services and Income Generation using Innovative Financing Catalyst
  • To promote innovations to increase access of energy services to rural poor through a multiple approach focused on income generation, innovative financing mechanisms and service delivery mechanisms.
  • Secondly, the project aims to ensure that more energy services-based income-generating products, new credit mechanisms and creative marketing methods are infused into the targeted markets.
