The principle governing the indices, apart from a regional or global focus, is that some focus on clean energy technologies while others focus on the broader alternative energy transition. Other factors which differentiate the indices are whether they:
The RENIXX World (Renewable Energy Industrial Index) was established in May 2006 and is the first global stock index, which comprises the performance of the world's 30 largest companies of the renewable energy industry whose weighting in the index is based on the market capitalization. Companies must achieve at least 50 percent of their revenue in the renewable energy industry coming from the wind energy, solar power, biomass, geothermal energy, hydropower or fuel cell sector to be included in the index.
Run by International Economic Platform for Renewable Energies (IWR)
Tracking 138 companies the ALTEX Global is the world's largest Alternative Energy Index with an aggregated market capitalization of $1.16 trillion USD [1]. The focus is on pure play companies involved in the transition to diversified low-emissions energy infrastructure. Sub-sectors tracked are: low-emission utilities, renewables, natural gas, energy minerals, hydrogen, and clean energy technologies. The index is rule based and the constituent list includes the top 25 global companies in all sub-sectors except hydrogen where all companies are included.
Run by Bakers Investment Group
Tracking 111 companies [2]. The focus is on pure play companies using a rule based approach which is inclusive in the clean energy technologies sector. Companies are involves in the following areas of focus: alternative energy resources (technologies for solar, wind, hydro, tidal, wave, geothermal and bio-energy); distributed generation technologies; environmental technologies including water and air quality; energy efficiency; and, enabling technologies including electronic, batteries, superconductors and advanced materials.
This index treats alternative energy as a “diversified technology,” according to Credit Suisse [3]. The index comprises 30 companies in five sub-sectors: Natural Gas, Wind, Solar, Bio-energy/Biomass, Geothermal/Hydropower/Fuel cells/Batteries. At the inception date and then at each Rebalancing Date, all five sectors will be capped to 20% to prevent individual sectors from dominating the Index. Stocks selected are major players in their Alternative Energy sectors and/or Alternative Energy activity represents at least 20% of the company’s annual sales.
The DAXglobal Alternative Energy Index tracks the performance of 15 alternative energy companies [4]. Companies which are selected for the index must generate more than 50 percent of their revenues in one of the following five sub-sectors: Natural Gas, Solar, Wind, Ethanol, Geothermal/Hybrids/Batteries. The DAXglobal Alternative Energy Index has a transparent, rule-based structure. The index comprises three constituents each from five the five sub-sectors, with equal sector weightings. Within each sector, constituents are selected on the basis of market capitalization, and of a minimum average exchange trading volume of USD 1 million.
DB Climate Change Advisors, the climate change investment and research branch of Deutsche Bank's asset management business, and NASDAQ OMX Group, Inc created the DB NASDAQ OMX Clean Tech Index. The index comprises 119 companies identified by DBCCA from a global universe of ~4,000, each with at least a third of revenues derived from clean technology within investable geographies and exchanges identified by NASDAQ OMX. Of these, 106 companies have over 50% clean tech revenue, with only identifiable revenue from filed financial statements used for the index. Constituent companies must have market capitalization of at least $250 million as of 12/31/09 and over $1 million average daily dollar trading volume for the three months prior to 12/31/09. Covered sectors include clean energy, energy efficiency, transport, waste management and water. http://www.dbcca.com/dbcca/EN/products_2286.jsp
The S&P Global Clean Energy Index tracks 30 companies from around the world that are involved in clean energy related businesses [5]. The index is based on a diversified mix of Clean Energy Production and Clean Energy Equipment & Technology companies including a number of firms involved in wind and solar. The index uses a rule based approach. The aggregate market capitalization is around US$ 224 billion.
This index tracks 86 companies that concentrate on renewable energy technologies and processes, with an emphasis on clean power and energy efficiency (the latter including both storage and demand-side management)[6]. The index uses a rule based approach to identify companies active in wind, solar, bio-fuels, hydro, wave and tidal, geothermal and other renewable energy businesses, as well as energy conversion, storage, conservation, efficiency materials, pollution control, emerging hydrogen and fuel cells. Diversification is provided by an equal-weighting methodology modified by sector and market capitalization bands.
Run by Société Générale, the Index tracks the 20 largest stocks involved in: Renewable energy (solar, wind and biomass). Energy efficiency (better use of energy generation, which involves industries such as energy meters and superconductors). and Decentralized energy supply (power generation in close proximity to the consumer, involving micro-turbines and fuel cells). WAEX is an equally weighted benchmark, that is the weight of each member is set at 5% on quarterly basis.
Designed and launched as the ET50 in 1999 by Impax Asset Management, the index was re-branded the FTSE ET50 in December 2007 after FTSE Group, in partnership with Impax, took over calculation and management. The FTSE ET50 Index measures the performance of the largest 50 companies globally whose core business is in the development and deployment of environmental technologies (at least 50% of their business must be derived from ET). This includes alternative energy, water treatment, pollution control and waste management companies. FTSE has set up an independent committee of clean technology and investment professionals to govern the research and management of the FTSE ET50 Index. The Chair is Winston Hickox, former Secretary of the State of California Environmental Protection Agency who also designed and implemented the environmental investment mandates for the California public employees retirement fund, CalPERS.FTSE Environmental Technology Index Series
Aligned with the FTSE ET50 Index, this index measures the performance of a broader basket of over 450 global stocks that have at least 20% of their business derived from environmental markets and technologies. Environmental Technology business activities include alternative energy, water treatment, pollution control and waste management.

Tracks the 42 Clean Energy companies on US exchanges: specifically, businesses that stand to benefit substantially from a societal transition toward use of cleaner energy and conservation. Stocks and sector weightings within the WilderHill Clean Energy Index are based on their significance for clean energy, technological influence and relevance to preventing pollution in the first place[11]. The index has six sub-sectors: renewable energy harvesting; power delivery and conservation; energy storage; cleaner fuels; energy conversion; and, greener utilities. Companies in the Clean Energy Index generally will not have their majority interests in the highest-carbon fuels: oil or coal. Large companies with interests outside clean energy may be included if they are significant to this sector. There is a strong bias in favor of the pure-play companies in wind power, solar power, hydrogen and fuel cells, bio-fuels, and related fields; companies in relevant fields such as hydroelectric, geothermal, wave, tidal, waste heat recapture and others are considered with respect to carbon content, the impacts upon marine and terrestrial biodiversity, and degree to which they advance or reflect the clean energy sector. ECO components are evenly divided within a sector to assign weights.
