General Electric sharply increased its revenues from environmental goods and services last year, and more than doubled its future order book from these businesses.

The company will announce on Wednesday that revenues from products and services gathered under its Ecomagination brand, for environmental products, rose from $6.2bn in 2004 to $10.1bn in 2005, and the company’s backlog of advance orders, mostly to be fulfilled in three to five years, has risen to $17bn.
