But using rare earths could reduce the per megawatt cost of wind energy and improve its competitiveness through savings on other materials, like steel and copper.

但是，如果在制造过程中采用稀土的话，可以有效的降低每兆瓦风能的成本，并且可以通过节约像钢和铜这样的金属，来提高产品的竞争力。

Same would go for steel and memory chips among older industries, and solar cells, wind turbines and high-speed trains among new industries.

在一些比较老旧的行业如钢铁、记忆芯片，在新兴的行业如太阳能电池、风力涡轮机、高速铁路等，情况也是一样的。

Costs for coal are highly dependent on the cost of gasoline, and the costs for wind are highly dependent on material costs like steel and concrete as wind requires about 10 times the amount of steel, concrete and copper per kWhr than any other energy source.

FORBES: The Naked Cost of Energy -- Stripping Away Financing and Subsidies

The existing structures could be strengthen with the use of peripheral steel beams that allow for high velocity wind to filter through the platform without obstructions.

FORBES: Audacious New Concept Turns Oil Rigs Into Luxury Homes

Cheaper steel and copper should help reduce the cost of making wind turbines.
