) -- China, the world's largest producer of carbon emissions, could also become a global giant in the fight for green energy through solar power.

Economies of scale have helped to reduce the costs of solar energy production, and China's massive workforce may soon be supplying the globe with cheaper solar solutions.

The U.S. and China, who both stand at the center of the

climate talks

in Copenhagen, will be looking to cut emissions while trying not to compromise growth.

The pressure is on developed countries, like the U.S., to cut carbon emissions and

implement alternatives

. China, which is able to produce these technologies at increasingly cheaper prices, could become a key player in the global implementation of solar power.

, focus specifically on the development of solar energy worldwide.

Both TAN and KWT track companies that derive their revenue from the solar energy industry and related products and services. Both funds also are tied to the success of solar in the U.S. and China. When it comes to country allocation, more than 55% of TAN's portfolio is allocated to solar firms in the U.S. or China. More than 56% of the firms that comprise KWT's underlying portfolio are in the U.S. or China.

Both TAN and KWT share top China-based holdings like

Trina Solar


. All three of these companies have helped to contribute to China's 30% share of the global market for solar panels, since all three firms export most of their products to the U.S and Europe.

China's ability to produce solar panels at a cheaper point has contributed to two phenomena: a 30% drop in world solar power prices, and an increased focus in countries like the U.S. to produce innovative products with unique technology to distinguish theirs from the influx of panels from China.

One U.S.- based solar energy provider that had managed to stay a dominant player in the global solar energy market is

. Both TAN and KWT count FSLR among their top components. First Solar uses cadmium telluride to convert sunlight into electricity, while more than 85% of solar panels worldwide are higher-cost silicon-based models. Since FSLR closely guards its unique, low-cost process, imitators abroad have been unable to replicate its technology.

The dominance of U.S.-based solar energy firms like FSLR prove that countries need to be both cost-efficient and innovative to succeed in the solar energy business. While China may be able to reproduce existing solar technologies more cheaply, innovative companies in the U.S. and Europe will still

stand a chance

in this competitive business.

While China will continue to argue that new international energy agreements should make fewer demands on emerging economies, it is indisputable that most of the world's carbon emissions will come from these emerging markets in the future.

As the Copenhagen talks continue, and pressure is put on both emerging markets and developed markets to curb carbon emissions, the firms that comprise KWT and TAN could benefit as a result of compromises.

Whether the companies that make up KWT and TAN are producing solar panels for their own country, or exporting them to emerging or developed markets abroad, demand for the least-expensive and most innovative solar technology will continue to grow.
