Last week I wrote about Green: Net, a green IT and tech conference being held March 24 in San Francisco by the good folks at Giga:Om's Earth2Tech. They made a call for submissions from startup companies that are using the web, cell phones, wireless networks and software to combat global warming and got a big response.

The window for submissions closed on Friday, and Earth2Tech has announced the 10 best entries who will make a presentation about their business at the Green: Net conference.

Here are a couple that caught my eye. Head over to Earth2Tech to get the full list.

Farmsreach is a beautifully designed site that will help connect farmers and the people that buy food — restaurants, stores, distributors and institutions. Anything that can bring some of the efficiency of scale and distribution that comes with large-scale factory farming down to the small- and medium-sized local farms is a good thing. I'm going to track the development of this one.

Wattbot is a website that will build a detailed profile of your home, its energy use and the most cost effective ways to deploy renewable energy systems and boost efficiency. Their site then shows a list of products you can buy from their list of service providers to achieve your greener home goals. They even offer financing options and build financial models showing monthly savings and the return on investment. They even throw in a little social networking for kicks.

Swing over to Earth2Tech and see the other eight green startups that will be hitting the stage at Green: Net in March.

Shea Gunther is a podcaster, writer, and entrepreneur living in Portland, Maine. He hosts the popular podcast "Marijuana Today Daily" and was a founder of Renewable Choice Energy, the country's leading provider of wind credits and Green Options. He plays a lot of ultimate frisbee and loves bad jokes.
