The principle governing alternative energy indexes, 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:

  • focus on pure play companies – that is on companies which are principally engaged in the field of alternative energy and excludes those companies for which alternative energy is peripheral to their main business.
  • use a rule-based approach – that is a clearly defined rules-based methodology, usually overseen by an impartial Index Committee, employing a pre-defined screening methodology ensures that the process is consistent and transparent.
  • are inclusive – that is strives to include all companies that are principally engaged in the field of alternative energy within a given market, a given region, or globally. Some indexes set a liquidity or market capitalization filter while others track just a predetermined number of companies (i.e. the top 15 or the top 20).

Global Alternative Energy Indexes[edit]

RENIXX World[edit]

The RENIXX World (Renewable Energy Industrial Index)[1] 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. RENIXX World is 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.[2] 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. ALTEXGlobal is run by Bakers Investment Group.[3]

Credit Suisse Global Alternative Energy Index[edit]

This index treats alternative energy as a “diversified technology,” according to Credit Suisse.[5] 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.

DAXglobal Alternative Energy Index[edit]

The DAXglobal Alternative Energy Index tracks the performance of 15 alternative energy companies.[6] 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.

NASDAQ Clean Edge U.S. Liquid Series Index[edit]

The Index tracks companies that are primarily manufacturers, developers, distributors, or installers of clean-energy technologies. The QCLN exchange traded fund (ETF) is based on the Index and is sponsored by First Trust Advisors L.P. To be eligible for inclusion in the Index, the security must be listed on NASDAQ, NYSE or AMEX.[15]

Issuers of the security must be classified, according to Clean Edge, as technology manufacturers, developers, distributors, and/or installers in one of the following sub-sectors:

  • Advanced Materials (nanotech materials, advanced membranes, silicon-based materials and alternatives, bioplastics, etc. that enable clean-energy technologies and/or reduce the need for petroleum-based materials);
  • Energy Intelligence (conservation, automated meter reading, energy management systems, smart grid, superconductors, power controls, etc.);
  • Energy Storage & Conversion (advanced batteries, hybrid drivetrains, hydrogen, fuel cells for stationary, portable, and transportation applications, etc.); and
  • Renewable Electricity Generation & Renewable Fuels (solar photovoltaics, concentrating solar, wind, geothermal, and ethanol, biodiesel, biofuel enabling enzymes, etc.)

WilderHill Clean Energy Index[edit]

Tracks the 42 Clean Energy companies on US exchanges: specifically, businesses that can 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.[16] 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.
