The Green Seen
Several items relating to the business and technology of clean energy and the environment caught our attention this week:
Transmission companies are eying high-voltage underwater cables to carry more renewable power over long distances without having to erect unsightly towers and carve out wide corridors. Toronto-based Transmission Developers proposes to run a 370-mile cable from north of the Canadian border along the bottom of Lake Champlain and down the Hudson River to supply hydroelectricity to New York City. A 53-mile power cable has been placed under San Francisco Bay and an underwater line linking New Jersey to Long Island now carries 22 percent of Long Island's electricity. There are other plans to deliver wind energy from the Hawaiian islands of Molokai and Lanai to Oahu and from Maine along the Atlantic coast to Boston.
The global renewable energy industry gained ground in 2009 despite the recession and a revenue drop in the solar business, according to an annual report from research firm Clean Edge Inc. The overall industry spent $63.5 billion on wind farms and turbines, a 23.5 percent gain from 2008 helped by government stimulus money. The global biofuel business rose 29 percent to $44.9 billion. Solar power manufacturers fell by 20.3 percent to $30.7 billion due to a drop in the price of solar panels.
Solazyme Inc., a South San Francisco-based renewable oil and bioproducts company and a leader in algal biotechnology, was selected No. 1 in sustainable biofuels technology at the 2nd Annual Sustainable Biofuels Market conference in Amsterdam. Solazyme is working on improving the efficiency and sustainability of biofuels production. Since the company's start in 2003, Solazyme says it has produced the world's first algae-based renewable diesel, the first 100 percent algae-based jet fuel and road-tested the first algae-derived biodiesel.
Snack food giant Frito-Lay is going green with what it's calling the first compostable chips bag for its SunChips brand. The bags are made from corn and will break down within 14 weeks, the company says. "In a hot, active compost bin it will definitely compost within that time period," said Brad Rogers, Frito-Lay's North American manager of sustainable packaging. However, there's some doubt that many bags will reach a compost bin. "Few Americans compost in their backyards, and curbside pickup is typically limited to Western metropolises like the Bay Area and Seattle," says Green Inc.
