Alternative energy. Trash to treasure. Green is the new black. Green is the new red. Organic foods go mainstream. These are just some of the catch phrases buzzing around the planet. From flowers and cotton to food and fashion, eco-friendly is where it's at these days.

Yes folks the world is going green and now is the time to cash in and start your own eco-friendly green business. Want to know which green businesses are best? Look no further. We've got the scoop on the top 10 green businesses to start in 2007. Go green and make some green. It's only going to get greener, er, better from here!

1. Natural and Organic Foods
   Natural and organic foods are hot commodities despite the naysayers who don't believe it's any better for you than conventional foods. Even Wal-mart's selling organic foods these days. If they can, you sure can.

2. Organic Clothing and Accessories
   Eco-fashions made from organic and dye and pesticide free fibers (think cotton), and sustainable fibers like soy silk and bamboo fiber are catching on. Even famous designers are cashing in.

3. Natural Beauty and Personal Care Products
   Ever heard of mineral makeup? It's a natural beauty product containing no dyes, perfumes, or any other artificial substances--and it has caught on like wildfire. With more studies cropping up every day about how soaps, body washes, shampoos, and makeup contain substances that are not good for us, the market for natural skincare and other products has risen dramatically in recent years.

4. Green "Home Depot"
   

   Home improvement continues to be a big trend, but more people are demanding eco-friendly building products that are formaldehyde-free, made with renewable resources like bamboo or cork, and use recycled materials to make floor tiles and other eco-friendly products.

5. Organic Flower Grower
   According to a group of California flower growers, 2007 is going to be the year that the public finally catches on to organic or "green" flowers. Organic flowers are grown using sustainable practices and without pesticide, look just as good, cost about the same, and smell even better than conventional ones.

6. Hydroponic Herb Grower
   Hydroponic herbs are grown in water using fairly simple equipment, no soil required. You've probably seen hydroponic herbs at the supermarket, those really fresh and healthy looking basil, oregano, and parsley still in their pots. Think health conscience consumers who want fresh produce and you've got your target market.

7. Eco-friendly House Cleaning Service
   Nowadays who doesn't hire a housekeeper or use a cleaning service? Beat the competition with a housecleaning service that only uses non-toxic, people, pet, and eco-friendly cleaning products.
8. Household Recycling Units
   Kitchen waste, garden waste, plastic bottles, cans, and cardboard all take up space in landfills—and we're running out of room. Capitalize on the need to recycle by selling self-contained household recycling units that crush and compact plastic and metal, or composters that turn kitchen waste into compost for the garden without any odors.

9. Green Rental Car Agency
   Green rental car agencies rent "green" cars like the hybrid Toyota Prius. The corporate environment is getting greener with every passing year. Who rents cars? Business people. What better way to show that a company cares about the environment than to make a "green" car rental a priority?

10. Residential Wind Power Generators
    This may not be the "coolest" business idea on the list (no pun intended), but the potential for growth is enormous. Residential wind generators capture the power of the wind and turn it into electricity for home use. Consumers can save money while saving the planet. And, in some municipalities, electric companies will even buy back any extra electricity that's generated by consumers.
